Flash Changelog

0.17.3

2026-11-02

freemkv Flash

• Support the audited BDR-212U 1.01 to BDR-213U 1.02 crossflash with a guarded startup-record conversion, verified drive-data backups, and a saved temporary-firmware recovery archive.
• Preserve startup settings and refuse unvalidated persistent-record conversions, including when the hardware-family check is bypassed.

0.17.2

2026-11-02

freemkv Flash

• Preserve original hardware settings across supported Pioneer firmware changes, including the reviewed UD02/UD03/UD04 adaptations and returns to OEM firmware.
• Fix Pioneer recovery being incorrectly blocked by a settings check for a different hardware family.
• Show settings guidance when a Pioneer firmware change has no reviewed settings mapping.
• Add Save Log after successful operations.
• Give the macOS Flash window more vertical room.
• Report ordinary and hardware-dependent firmware routes through one planner, including exact original-hardware checks in the firmware finder.
• Keep the existing hardware-family filters unchanged.

0.17.1

2026-11-01

freemkv Flash

• Improve Pioneer crossflash compatibility checks.
• Fix valid modified MediaTek Current firmware being rejected during flash planning.
• Fix MediaTek recovery handling in boot mode.
• Improve diagnostic logging for failed or blocked flash and recovery attempts.

0.17.0

2026-11-01

freemkv Modify

• Repair UHD disc-information handling, geometry and capacity calculations in supported classic MT1939 firmware, and apply source-validated UHD repairs to older MT1959 firmware. Preserve native UHD handling in newer MT1959 firmware.
• Fix Modify skipping supported features because of drive-model capability labels. Detect support from validated firmware instructions, and report settings on already-modified firmware from its verified installed support record.
• Clear stale authentication when Encryption changes from Off to On or OEM, including when settings are reset.
• Correct the host setting values for maximum read speed and region-free DVD responses. Region-free reports DVD RPC-1; Blu-ray region forcing is not implemented.
• Validate modified outputs for 123 OEM firmware inputs in software. Physical UHD reads, layer transitions and settings persistence still require hardware testing.

freemkv Flash

• Allow matching Pioneer BDX-PR1ML and BDR-211M SAT 8801 platforms to share a hardware family. Preserve all other hardware evidence, raw register values and the existing settings requirements.

0.16.2

2026-11-01

freemkv Flash

• Fix the supported BDR-UD02D 1.00 to BDR-UD04 1.14 conversion being rejected on UD02FAN units. Flash and Recovery now select this conversion by the certified firmware pair, without requiring a factory product code.
• Preserve the required live mechanism setting, firmware integrity checks, verification and rollback. The certified converted firmware can return to stock UD02 1.00; native UD04 to UD02 remains unsupported.

0.16.1

2026-10-31

freemkv Flash

• Use consistent stage terminology in flashing interfaces and bridge classification.

• Use prepared stages for direct and intermediate firmware updates, including downgrade markers, startup settings and receiver-specific transfer formats.

• Prepare recognized Pioneer Kernel-handoff bridges from firmware evidence, retaining the installed Normal for the bridge before writing the requested target. These new bridge routes still require physical hardware qualification.

• Validate the complete sequence before writing, verify each stage, and retain completed-stage information if a later stage fails. Show bridge requirements consistently in Flash and Recovery.

• Consolidate MediaTek direct and packaged-intermediate execution while retaining existing receiver checks, transfer encoding and verification behavior.

0.16.0

2026-10-31

freemkv Modify

• Expand media conversion for supported classic MT1939 and older MT1959 firmware, with per-image Speed, Region, Encryption, HRL and Unrestricted settings. Refuse incomplete conversions and unsupported firmware layouts.
• Preserve boot settings and private media identity across supported startup and reset paths, with stronger checks before producing modified firmware.
• Reduce firmware analysis and creation time while preserving generated output.
• Physical UHD reading is not yet confirmed for the newly supported conversions. Some authentication differences remain unresolved. Hardware reports for BH16NS48 1.02 and ASUS BW-16D1HT running WH16NS58 1.V9 are pending.

0.15.4

2026-10-30

freemkv Flash

• Add a narrowly qualified BDR-UD02D 1.00 to BDR-UD04 1.14 route. Flash checks the exact firmware, original-hardware evidence and live calibration before offering the write. Other UD02/UD04 combinations remain unsupported.
• Recognize additional complete Pioneer factory records and improve OEM backup capture guidance when a raw drive dump cannot be reconstructed as a flashable backup.

freemkv Modify

• Expand exact-image MediaTek modification support and report available features and boot settings for each firmware image. Experimental MT1939 UHD conversion is not included in this release.

0.15.3

2026-10-25

freemkv Flash

• Explain MediaTek firmware read restrictions before Flash, Backup and Dump. Explicitly rejected backup reads are an expected limitation, with no firmware write, rather than a generic connection failure or automatic report request. Incomplete diagnostic dumps remain clearly unsuitable for restoration.
• Show DVD region reset counters and lock state only for RPC-2. RPC-1 reports region-free status without presenting its zero fields as exhausted budgets.
• Correct disconnect classification, unsupported-comparison severity, backup reconstruction limitations and no-backup guidance after a personal review of every error catalogue entry and the operation/confirmation boundaries.
• Add the shared, compiled-in settings adaptation framework and independent original-hardware checks. The production profile registry is empty: supported firmware transitions and website crossflash decisions are unchanged. Synthetic tests cover exact matching and UD02-only stock-return prerequisites.

freemkv Modify

• Show only relevant region information when inspecting a drive after applying Region-free. No firmware hook behavior changes in this release.
• Align website feature listings with each exact image’s Modify capability report. Engine family and native UHD support no longer imply an available UHD/BD modification. WH16NS58 1.V9’s unavailable combined control is no longer advertised as supported.

0.15.2

2026-10-25

freemkv Modify

• Allocate injected MediaTek code outside integrity metadata and preserve integrity-table descriptors and unused slots. This fixes the reproduced WH16NS58 1.V9 corruption during modification.
• Modify now signs and verifies generated firmware automatically. The CLI command is freemkv-fw modify INPUT [OUTPUT]; existing create scripts remain compatible.
• Treat an already-enabled modification as a successful no-op, and apply the classic MediaTek HRL change independently when raw-read patching is unavailable.

freemkv Flash

• Reject overwritten MediaTek integrity-table metadata before flashing, even when stored region hashes match.
• Include the exact firmware inputs used by an update in diagnostic archives and maintainer emails, with filenames and SHA-256 hashes. Missing inputs are recorded explicitly.
• Check for a newer stable release at startup and explain confirmed updates. Failed update checks leave normal use available; automated reports pause until the app is updated.
• After a verified flash without an attachment, ask whether a diagnostic report is needed. Report submissions require a description, which is included in the maintainer email.

0.15.1

2026-10-25

freemkv Flash

• Give clearer guidance for corrupt firmware files and updates whose required settings have not been validated.
• Distinguish the factory product code from the installed firmware model, and label the factory test date accurately in drive details.

0.15.0

2026-10-24

freemkv Flash

• Keep prepared recovery firmware through confirmation and check the connected drive again before writing.
• Show reading, writing, restart and verification progress across supported drives.
• Explain incomplete firmware and operation failures in the selected language, including whether anything was written and what to do next.
• Verify Pioneer updates through firmware readback and startup while reporting Kernel, Normal and startup results separately.

0.14.5

2026-10-24

freemkv Flash

• Let Recovery explicitly bypass a confirmed Pioneer family mismatch with a translated risk warning and a fresh five-digit confirmation. The override applies to one Recovery attempt; regular Flash continues to enforce the family check.
• Identify Pioneer and MediaTek drives from validated protocol responses, including supported OEM-branded hardware, while preserving transport errors and unsupported-command details.
• Verify Pioneer firmware through exact Kernel and Normal readbacks and startup evidence, and report each result separately.
• During Recovery, an unsupported-media readiness response can proceed to the existing target identity and exact readback checks. The response alone never counts as verification, and normal Flash readiness checks are unchanged.
• Separate exact content, filename, version direction and hardware-family evidence in firmware comparisons.

0.14.4

2026-10-23

freemkv Flash

• Show CLI drive information in grouped, aligned sections using the same identity and capability fields as the GUI. Keep native transport traces in diagnostic logs instead of flooding the terminal.
• Accept standalone BIN files and TAR packages for MediaTek in both Flash and Recovery. Pioneer updates continue to require TAR packages. File pickers and validation now share the same backend format rules.
• Use pioneer-optical 1.0.2 to analyze compressed and uncompressed firmware consistently for hardware families, UHD capability and Kernel ABI requirements.
• Track Pioneer FE9F interface setup as a family signal, including explicit zero-valued register initialization writes.
• Restore matching between BDR-S08 and BDR-S11JX SAT 8800 firmware whose equivalent servo rows were stored in different regions or orders. Distinct SAT 8801 board evidence remains separate.
• Reject unresolved compressed firmware evidence instead of scanning compressed bytes as instructions. Hardware-family catalogs use the new pioneer.hardware.v3 scheme.

0.14.3

2026-10-23

freemkv Flash

• Allow raw dump attempts on Pioneer REC drives and other valid Pioneer hardware identities previously reported as Unknown. Actual read coverage depends on the drive; unreadable regions remain recorded in the dump.
• Offer Save raw dump when an OEM backup is unavailable or a backup attempt fails.
• Submit a completed dump or backup with diagnostic logs and session history using Submit Dump or Submit Backup. Uploads require browser approval.
• Recognize 32 additional Pioneer SAT firmware images when reconstructing OEM backups. ATA, SCSI and REC OEM backup construction is not yet supported.

0.14.2

2026-10-22

freemkv Flash

• Include servo coefficient evidence when matching Pioneer hardware families, including boards that previously skipped it. This separates firmware patterns formerly grouped together, including SAT 8000 versus 8680.
• Use pioneer-optical 1.0.1 for both firmware selection and receiver family gates.
• Report flash failure milestones and localized error outcomes consistently across frontends.

freemkv Modify

• Preserve specific integrity-verification guidance and report background worker failures in diagnostic logs.

0.14.1

2026-10-21

freemkv Flash

• Ask whether to proceed when a backup cannot be made, including the normal read restrictions on many MediaTek drives. Choosing Yes still requires final confirmation before flashing.
• Require a Current firmware file when the drive cannot provide its installed firmware automatically. Flash and Recovery show the same controls for the selected drive.
• Translate operation forms, confirmations, results and error guidance in all 29 UI languages. Diagnostic logs remain in English.
• Show concise errors with a next step, while keeping command details and full failure causes in diagnostic logs.
• Put View Log, Save Log and Submit Report together in one row, and remove repeated operation labels above the tabs.

freemkv Modify

• Add a saved language preference and translated controls, startup settings, results and error guidance in 29 languages. Diagnostic logs remain in English.
• Restore missing Raw Read patching and HRL/encryption startup options when modifying WH16NS58 1.V9 firmware.

0.14.0

2026-10-21

freemkv Flash

• Add a saved language preference and initial translations for common controls and menus in 29 languages. Translation of operation details and error messages is still in progress.
• Show the correct application version in macOS app information.
• Fix misleading Pioneer errors for unrecognized MediaTek TAR files. Invalid packages now report a package error before any write.
• Let MediaTek Flash use a selected Current firmware file when the drive blocks automatic detection. Read from drive remains the default; failed detection now explains how to select the installed firmware.
• Give Flash and Recovery matching firmware-selection layouts, with Read from drive selected by default in both desktop forms.
• Make MediaTek Recovery consistently use the Current firmware file you select and report when it does not match the drive.
• Clearly distinguish a blocked precheck from a failed update, and show when no firmware was written.
• Explain incompatible hardware using the installed and target firmware models, with technical identifiers kept in diagnostics.
• Make Pioneer previews clear that passing package checks still requires a drive compatibility check before writing.

freemkv Modify

• Fix firmware creation and editing startup settings for WH16NS58 1.V9 and other affected firmware.
• Explain when an input is already modified and a clean OEM firmware file is required.

0.13.4

2026-10-20

freemkv Modify

• Choose firmware startup settings in the desktop app or with the CLI’s repeatable --default FEATURE=VALUE option. The selected settings apply every time the drive starts.
• Reset startup settings to the standard defaults: unrestricted disc access On, with HRL, encryption, speed and region at OEM behavior.
• Reopen newly created BIN or TAR files to edit their startup settings. Older modified images still require their original OEM source.
• Switching or reselecting an image now reloads that image’s settings, so choices from a previous file cannot carry over accidentally.
• Unsupported settings are explained before creation. Use --dry-run to preview the result without writing an output file.

freemkv Flash

• Preview Recovery’s planned transfers, including any temporary firmware and restoration steps, before confirming a write.
• Flash and Recovery results are easier to follow, with a concise status and direct View Log and Submit Report actions.
• Save session history and operation logs automatically. Detailed errors remain available for viewing and export even when file logging fails.
• Cancel a report submission, and avoid indefinite waits when the reporting service is unavailable.
• Fix Pioneer Recovery downgrade preparation for the reported WX1DM 0000 to S12JX 1.03 case. A failed restoration is reported explicitly.
• Fix preparation of the MediaTek INTM to 1.V9 transition while preserving the drive’s boot region. Physical-drive confirmation of this transition is still outstanding.
• Improve recognition of Pioneer-based PLEXTOR and TEAC firmware and avoid false revision mismatches.
• Clear stale results when the selected firmware or drive changes. Incomplete verification and temporary firmware states are reported clearly.

0.13.3

2026-10-19

freemkv Flash

• Fix the preflight refusal reported when changing a Pioneer BDR-207M from 1.60 to BDR-PR1ML 1.30.
• Prepare the drive’s startup setting for the target firmware in both Flash and Recovery. A failed setting change stops before firmware transfer.
• Recovery from an already-running loader continues without attempting settings commands that require normal drive operation.

0.13.2

2026-10-19

freemkv Flash

• Prepare Pioneer startup settings for compatible firmware changes, including the reverse transition.
• Report the last observed readiness and identity when a drive does not return to normal operation after Flash or Recovery.
• Recovery from an existing loader no longer attempts unsupported persistent-settings commands.
• Physical-drive confirmation of the supplied S12JX/WX1DM transition remains outstanding.

0.13.1

2026-10-19

freemkv Flash

• Complete paired MediaTek updates through restricted intermediate firmware, rechecking the drive before the final transfer.
• Select an optional Current firmware reference and its TAR member in MediaTek Recovery. A stale reference is rejected when intermediate firmware is already running.
• Report limited verification when a drive cannot provide protected readback. Write failures and readback mismatches still stop the operation.
• Recognize additional Pioneer-based drives without relying on an exact product-name list.
• Restore supported Pioneer backups with missing signatures and accept the reported WX1DM 1.01 backup layout. Original backup files are preserved.
• Show whether selected firmware is likely OEM, user-provided or of unknown origin. This information does not establish compatibility.

0.13.0

2026-10-16

freemkv Flash

• Improve MediaTek Flash and Recovery preparation for drives running normal firmware, intermediate firmware or their boot loader.
• Improve diagnostics when Recovery preparation fails.
• Fix Pioneer transfer preparation when a package includes a replacement Kernel.
• Keep tabs and controls accessible when a drive’s profile is unsupported or unavailable; each operation explains whether it can proceed.
• MediaTek Recovery remains experimental and requires physical-drive validation.

0.12.5

2026-10-16

freemkv Flash

• Add experimental MediaTek Recovery, including drives that cannot supply a Current reference or rollback backup.
• Accept MediaTek release TAR packages, including declared intermediate-to-final updates. Stop if the intermediate firmware does not start correctly.
• Accept standalone BIN files for Flash and Recovery. A BIN writes only the supplied image; it does not add intermediate firmware.
• Add package to wrap a BIN as a single-image TAR.
• Choose transfer encoding automatically and refuse unknown or conflicting receiver information.

freemkv Modify

• Modify firmware inside MediaTek release TAR packages. Preserve the intermediate image and write the changes only to the final image.

0.12.4

2026-10-15

freemkv Flash

• Allow valid MediaTek intermediate firmware as the source or target of a compatible update.
• Improve failure messages when a firmware identity, readback region or restored backup cannot be verified.
• Keep drive-reported model, revision and serial information available when other metadata cannot be read.

0.12.3

2026-10-14

freemkv Modify

• Stop with a clear message and no output file when an image has no applicable changes. Already-modified images are identified explicitly.
• When only some modifications apply, show which succeeded and why the others are unavailable.

freemkv Flash

• Correct the displayed MediaTek generation for affected LG and ASUS drives. Existing backups with the older label remain usable.
• Explain when a MediaTek drive does not expose enough firmware for backup. Add the read-only dump --read-map diagnostic for support.
• Report drive-command rejections accurately, instead of describing every rejection as a connection failure.
• Fix Pioneer Kernel transfers that could fail while recovering between the BDR-205 and BDR-206 families.
• The CLI can proceed without a rollback backup when the drive hides its firmware and the operator explicitly confirms the risk. This option is unavailable in the desktop app or unattended operation.
• Back up MediaTek drives already running freemkv firmware even when their stock firmware did not expose its flash.

0.12.2

2026-10-14

freemkv Flash

• Restore compatible Pioneer cross-model updates that 0.12.1 incorrectly refused, including BDR-UD03 to BDR-UD04.
• Keep normal Flash refusals for firmware that requires a different receiver encoding, and direct those cases to experimental Recovery.
• Recovery re-encoding remains unconfirmed on hardware.

0.12.1

2026-10-14

freemkv Flash

• Refuse Pioneer updates that the installed firmware cannot receive or that would make the saved backup unusable.
• Add experimental Pioneer Recovery for supported same-hardware firmware transitions that normal Flash refuses. Physical-drive acceptance of the re-encoded firmware is not yet confirmed.
• Allow compatible MediaTek cross-model updates within the same hardware family. Different or unknown hardware families are refused.

0.12.0

2026-10-10

freemkv Flash

• Fix MediaTek backups on MT1939 drives, including LG BH14NS40 and BE14NU40, that previously failed with an unrecognized boot page.
• Identify known OEM firmware in backups, Inspect and Compare. Reconstructed backups are labelled separately.
• Refuse raw drive dumps as flash inputs when their boot page would not start the drive.
• Show corrupt MediaTek integrity data as invalid, and improve chipset information.
• Use a native desktop interface on macOS, Windows and supported Linux systems.
• Save the pre-flash backup before asking for final confirmation. Cancelling retains the backup and writes no firmware.
• Require an explicit risk acknowledgement before enabling the confirmation button. Enter and Escape cancel the dialog.
• Make Recovery available for recognized receivers even when normal drive classification is unsupported.
• Improve comparison results by separating expected per-drive differences from unexpected firmware changes.

0.11.2

2026-10-09

freemkv Flash

• Show DVD regions 1–8 when the drive permits all regions, and distinguish an unset region from a selected region.
• Show the original product code, factory date and country of manufacture when available.

0.11.1

2026-10-08

freemkv Flash

• Expand drive information with firmware identity, media capabilities, DVD region counters and supported Quiet Drive/PureRead information.
• Make capability details easier to compare and hide unsupported or unknown rows.
• Show current and saved Quiet modes together, and keep diagnostic log locations visible.

0.11.0

2026-10-08

freemkv Flash

• Add a separate Pioneer Recovery tab and recover command. Normal Flash continues to require its backup and compatibility checks.
• Remove flash --force; use Recovery for supported drives that cannot complete a normal update.
• Recovery accepts a Current firmware reference or an explicit read from the drive. Unsupported drives are refused before update commands.
• Recovery reports success only after normal drive identity and readiness return. This does not establish byte-for-byte readback, and the reported PR1ML recovery remains unconfirmed on hardware.
• Add Inspect for firmware files and captured drives, plus Compare with text and JSON export.
• Explain unsupported files and incomplete analysis without entering update mode.

0.10.9

freemkv Flash

• Fix Pioneer pre-flash backups that failed on drives with restricted firmware reads, including the reported BDR-212 case.

• Report failed OEM restoration instead of claiming the drive is working.
• Mark incomplete dumps clearly and stop recovery reads when the drive disconnects.
• Distinguish a refused update, a transfer failure and an update whose completion could not be verified.
• Include more available diagnostic information in Pioneer dumps; missing optional logging does not fail the dump.

0.10.7

freemkv Flash

• Identify drives using the names shown by the operating system, including Windows drive letters, so identical drives are easier to tell apart.
• Select a drive by its OS name or device ID. Numbered entries from list are no longer accepted as selectors.

0.10.6

freemkv Flash

• Save MediaTek backups as 2 MiB BIN files in update format, with per-drive settings and calibration replaced by factory contents. Raw dump output still contains per-drive data.

0.9.2

freemkv Modify

• Fix an incompatible-medium refusal affecting a triple-layer UHD disc on BU40N 1.00.
• Combine Blu-ray and UHD acceptance under the Unrestricted control. Existing hosts using the former UHD control remain compatible.

0.9.1

freemkv Modify

• Improve generation of firmware modifications. Existing hardware-validated 0.9.0 images do not require replacement for this change alone.

0.9.0

freemkv Modify

• Combine the former AKE and Bus controls into one Encryption control. Use freemkv 1.7.5 or newer with this firmware.
• Fix a drive starting with bus encryption disabled when configured to retain OEM behavior.

0.8.3

freemkv Modify

• Separate reset actions for saved settings, creation-time defaults and OEM behavior.
• Reset to OEM now clears saved freemkv settings. On the next startup, the firmware’s creation-time defaults apply.

0.8.2

freemkv Modify

• Keep Blu-ray and UHD acceptance enabled after restarting the drive, using the defaults selected when the firmware was created.
• Remember deliberately saved OEM-behavior settings instead of treating them as an empty configuration.

0.8.1

freemkv Modify

• Add support for additional MT1939 firmware variants, with feature availability reported per image.
• Add saved settings and reset controls for speed, region, disc acceptance and encryption-related features.
• Improve matching across supported OEM firmware variants.
