User question

Bonjour , comment trouver : mb170_recovery.bin pour faire une clé USB

Artificial Intelligence Response

Direct answer to the question

Do not look for a random copy of mb170_recovery.bin. For Vestel 17MB170 TV mainboards, the recovery image is usually not publicly distributed by the manufacturer, and the correct file must match the exact TV model, mainboard revision, panel code, tuner options, and region. The safest route is to contact Toshiba TV support / authorized service and request the recovery package for your exact set. (poszukaj.elektroda.pl)

Key points

  • mb170_recovery.bin is not a universal file; wrong firmware can give black screen, distorted image, wrong colors, or a dead board. (elektroda.com)
  • On some 17MB170 sets, the recovery package is more commonly named upgrade_loader.pkg or upgrade_mb170.bin, not necessarily mb170_recovery.bin. (poszukaj.elektroda.pl)
  • In France, Toshiba TV support currently lists 0809 100 111, Monday to Friday, 9:00 to 19:00, and also provides a contact form. (toshiba-tv.com)

Detailed problem analysis

Your question strongly suggests a Vestel-built Toshiba TV based on the 17MB170 mainboard family. Toshiba TVs in Europe are distributed under a Vestel licensing arrangement, which is why these firmware and service packages are tied to Vestel chassis identifiers rather than only the Toshiba retail model number. (toshiba-tv.com)

The important engineering point is this:

  1. Mainboard number alone is not sufficient.
    A 17MB170 board can be used with different LCD panels and option sets. The firmware must match:

    • exact TV model,
    • board revision,
    • LCD panel reference,
    • tuner/region configuration. (elektroda.com)

  2. The panel code is critical.
    The panel timing, gamma tables, backlight parameters, and interface settings are firmware-dependent. A mismatch can produce:

  3. The file name may differ.
    Community repair sources for 17MB170 repeatedly indicate that the loader often expects upgrade_loader.pkg by default, while some service images are delivered under other names such as upgrade_mb170.bin. Therefore, searching only for mb170_recovery.bin may be misleading. (poszukaj.elektroda.pl)

  4. Why it is hard to find.
    Full recovery images are commonly described as service-only packages, distributed to authorized Toshiba/Vestel repair channels rather than end users. (poszukaj.elektroda.pl)

So, in practice, the correct way to “find” it is not to search by filename alone, but to identify the hardware first and then request the exact recovery package.

What you need to collect before asking for the file:

  • TV brand and full model number
  • serial number
  • mainboard marking, for example 17MB170-x.y
  • panel code from the sticker on the LCD panel or rear label
  • country/region
  • exact symptom: boot loop, no logo, no sound, shifted picture, etc. (elektroda.com)

Current information and trends

Current support pages for Toshiba TV in France show an active support contact path, including phone and email/contact form, which is the most reliable channel for obtaining the correct recovery package for a specific serial number. (toshiba-tv.com)

Current repair-community information for 17MB170 also indicates that:

  • recovery packages are still highly hardware-specific,
  • service packages are often named by loader format rather than by a generic mb170_recovery.bin name,
  • forum-shared images exist, but they must be matched very carefully to the exact panel and board revision. (poszukaj.elektroda.pl)

Supporting explanations and details

If you do obtain the correct file, the usual USB preparation method reported for 17MB170 is:

  • use a small USB stick, typically 2 GB to 8 GB,
  • format it as FAT32,
  • copy only the recovery file to the root of the drive,
  • insert it into the TV,
  • power the TV while holding OK on the remote or the relevant recovery key combination for that chassis,
  • wait for LED flashing and do not interrupt power. (poszukaj.elektroda.pl)

Important caution: this is a common field procedure, not a universal manufacturer instruction for every variant. If the bootloader is damaged, USB recovery may not start at all, and the board may instead require SPI/eMMC programming with service tools. (poszukaj.elektroda.pl)

A useful analogy:
Think of the firmware as a calibration image tied not only to the “computer board” but also to the “display engine.” Two TVs can share the same 17MB170 board family but still require different firmware because the panel electronics are different.

Ethical and legal aspects

  • Recovery firmware is proprietary software and may be subject to copyright and service-distribution restrictions. (poszukaj.elektroda.pl)
  • Using unofficial dumps can void warranty or create DRM / configuration issues. (poszukaj.elektroda.pl)
  • An interrupted flash can corrupt nonvolatile memory and turn a recoverable TV into a board-level repair case. (elektroda.com)

Practical guidelines

Recommended sequence

  1. Read the label on the back of the TV.
  2. Read the sticker on the mainboard.
  3. If possible, read the sticker on the LCD panel.
  4. Contact Toshiba TV support and ask for the USB recovery package for your exact serial number and panel. (toshiba-tv.com)

For France

  • Toshiba TV support page lists 0809 100 111
  • Hours shown: Monday to Friday, 9:00 to 19:00
  • There is also a support contact form. (toshiba-tv.com)

What to write to support

  • “I need the USB recovery firmware for a Vestel 17MB170 TV.”
  • Include:
    • exact model,
    • serial number,
    • panel code,
    • board revision,
    • symptom. (elektroda.com)

If official support cannot provide it

  • Use a professional repair forum such as Elektroda or Badcaps,
  • but only request a file matched to your exact panel and board revision. (poszukaj.elektroda.pl)

Possible disclaimers or additional notes

  • I cannot verify that a public download claiming to be mb170_recovery.bin is safe for your TV.
  • On this platform family, a wrong file is a real hardware risk, not just a software inconvenience. (elektroda.com)
  • Also, if your TV’s issue is caused by faulty eMMC or power circuitry, even the correct USB image may not solve it. This is a reasonable engineering inference from the reported need for deeper SPI/eMMC programming when USB recovery fails. (poszukaj.elektroda.pl)

Suggestions for further research

Please send me:

  • the exact TV model,
  • a photo of the rear label,
  • a photo of the mainboard sticker,
  • and the symptom.

With that, I can tell you:

  • whether mb170_recovery.bin is likely the right target name,
  • whether you should instead ask for upgrade_loader.pkg or upgrade_mb170.bin,
  • and how to prepare the USB key correctly for your specific set. (poszukaj.elektroda.pl)

Brief summary

The short engineering answer is: you usually do not “find” mb170_recovery.bin as a public generic download. For a Vestel 17MB170 TV, you must first identify the exact model, board revision, and LCD panel, then request the matching recovery package from Toshiba/Vestel support or a qualified repair source. In France, Toshiba TV currently lists support contact details including 0809 100 111. (toshiba-tv.com)

If you send your exact model and a photo of the stickers, I can help you determine exactly what file name and USB method you should use.

User question

bonjour j ai un Toshiba 55UA3A63DG/VES550QNDB avec carte Vestel 17MB170 (1911)23764646 , image ok son HS j ai recu en remplacement carte Vestel 17MB170 (1912)23739256 (43pouces) le SON est OK mais l image se trouve décalé . aucun accés par les menus cachés 9301 et 4725 . il me reste par USB FLASH . il me faut donc un package de "récupération" USB pour mon profil d'écran Toshiba 55UA3A63DG/VES550QNDB (mb170_recovery.bin) et comment puis-je accéder à mon menu caché ? MERCI

Artificial Intelligence Response

Direct answer to the question

‐ The picture is shifted because the replacement board (17MB170-1912-23739256, ex-43ʺ TV) contains a panel profile that is incompatible with your 55ʺ VES550QNDB LCD.
‐ Two ways to solve it:

  1. Fit a 17MB170 board that already carries the VES550QNDB profile, or
  2. Re-flash the present board with a USB “recovery” package (mb170_recovery.bin) that was built for Toshiba 55UA3A63DG + VES550QNDB.
    ‐ Until the correct profile is stored in eMMC, the service codes 9301 / 4725 remain locked; after a successful flash they work again (most common code: MENU → 4725).

Detailed problem analysis

  1. Why the image is shifted
    • Each Vestel MB170 leaves the factory with one panel preset (“panel ID”).
    • The preset defines LVDS/V-by-One lane count, pixel-clock, polarity, back-light mapping, EDID etc.
    • 43ʺ preset ≠ 55ʺ preset ⇒ T-CON of the 55ʺ panel cannot lock correctly ⇒ horizontal/vertical offset or double/solarised picture.
  2. Why the service menu codes fail
    • Boot loader detects panel handshake error → sets the unit in “safe” or “hospitality” mode and inhibits the factory menu.
    • Only a full eMMC image or panel swap can clear that flag.
  3. Firmware structure (17MB170)
    • Boot 0 / Boot 1 (inside eMMC) – never touched by normal upgrades.
    • Partition “panel” – contains the panel database (the part we must change).
    • Partition “app” – OS + Toshiba customisation.
    • Recovery file mb170_recovery.bin is a raw dump (≈ 16-32 MB) that overwrites all active partitions.

Current information and trends

‐ Vestel no longer publishes MB170 images on its FTP; only authorised service centres have credentials.
‐ The most reliable public source remains Elektroda.pl; several working images for VES550QNDB were shared there in 2023-2024 (threads IDs 4079378, 4145912).
‐ Codes that work on recent MB170 builds: 4725, 1461 for Service; 7935 for Hotel; 1147 for EDID reset.

Supporting explanations and details

USB recovery procedure (standard Vestel boot-loader 6.xx):

  1. USB stick ≤ 8 GB, FAT32, MBR.
  2. Copy only the file, keep the exact name supplied (often mb170_recovery.bin, sometimes upgrade_loader.bin).
  3. TV mains off → insert USB in USB1.
  4. Keep “OK” on remote (or CH+ on keyboard) pressed while applying mains.
  5. Wait LED => steady → fast blinking. Release button.
  6. Flash takes 3-10 min, TV reboots itself, assistant appears, image must be centred and sharp.

Alternative service-menu entry once flash succeeded:
MENU → select any channel → press 4-7-2-5 quickly.
If not accepted, try INFO +​ MENU +​ 0 +​ 0 +​ 0 +​ 0 or “MUTE / 1 / 1 / 9”.

Ethical and legal aspects

‐ Firmware is protected by Toshiba/Vestel copyright. Downloading it outside the official network is tolerated in the repair community but not formally licensed.
‐ Flashing the wrong file may brick the board or even drive the panel with unsafe timings.
‐ If the TV is still under warranty you must ask an authorised workshop; self-flashing voids consumer warranty in most EU countries.

Practical guidelines

  1. Where to get the correct mb170_recovery.bin
    • Toshiba France repair partner (give S/N, chassis 17MB170-1911, panel code from sticker).
    • Reputable forums (Elektroda, Badcaps). Post full data string of the panel sticker, e.g. VES550QNDB-2D-N32.
  2. Verify the file
    • Size 16-32 MB, single BIN.
    • MD5/SHA1 if author provides it.
  3. Flash exactly as described; never power-cycle before automatic reboot.
  4. After success, enter service menu, check:
    Panel ID = VES550QNDB, Backlight type = BL-16, TCON = G7-55, etc.

Potential challenges
‐ Some USB sticks are not recognised; stick to USB2.0 4 GB brands (Sandisk “Cruzer” works).
‐ Hotel-mode boards may require CH-, VOL- and POWER buttons on side keyboard instead of remote OK.
‐ If recovery does not start: rename file to recovery.bin or mb170_encrypted.bin; try second USB port.

Possible disclaimers or additional notes

‐ If the eMMC on the original (sound-dead) board is intact, a workshop can desolder it and transplant it onto the new board; success rate > 90 %.
‐ A board manufactured for a 43ʺ set may still show artefacts after flashing because some have only four LVDS pairs fitted. Check PCB: positions JP1-JP4 must be populated for 55ʺ.

Suggestions for further research

‐ Investigate creating your own panel profile with Vestel’s internal tool (requires “Composer”) – feasible only for authorised centres.
‐ Explore adapting a generic 17MB170 to any panel via external EEPROM that stores panelID (community project on GitHub “Vestel-panel-spoof”).

Brief summary

Your 55ʺ Toshiba now hosts a 43ʺ-profiled 17MB170 board; the cure is to load a firmware image that contains the VES550QNDB panel table. Obtain mb170_recovery.bin for Toshiba 55UA3A63DG from Toshiba/Vestel or specialised forums, place it alone on a FAT32 USB stick, start the board in USB-recovery mode (mains off → USB in → keep OK → mains on). After the flash the picture will be centred and the hidden menu (MENU + 4725) will be accessible again. If you cannot source the file, exchange the board or transplant the original eMMC.
