Hitachi 50HAK5350 17MB170E - bootloop after failed update, full recovery firmware?

SavageVandal 627 15
Best answers

How can I recover a Hitachi 50HAK5350 17MB170E TV stuck in a bootloop after a failed update, and is there a compatible full recovery firmware?

The thread does not provide a confirmed full recovery firmware for this Hitachi 50HAK5350, but one reply points to a latest firmware file from Gaborxx that may work after registration; however, you should first verify the difference between MB170 and 170E because flashing the wrong firmware could brick the mainboard [#21927569][#21928674] Before reflashing, another suggestion was to try a reset or service mode procedure [#21926515] The only concrete hardware note added was that the set uses a V500QNDT-2D-N41 panel, while the questioned firmware mentioned VES500QNDH-N2-N45, so compatibility is uncertain [#21928104]

    Hello. I need a full recovery firmware for my Hitachi 50HAK5350 TV 17MB170E VES500QNDT-2D-N41. Can anybody help me?

    What is the problem with the TV now — stuck on logo, bootloop, no standby, black screen, or failed update?
    Bootloop and I think this is for a failed update. Recovery mode not helped.
    Can you provide the full label information from the back cover/mainboard, including serial number, chassis/version, and current software version if available?

    I try it several times, but the TV turns off and on at random times. That's why I try to make a force firmware update because it is my last chance before I change the main board. If anyone has got the correct firmware, please send me the link.

    I don’t know what the difference is between the MB170 and the 170E (SM attached), but
    - after registering at Link , delete the batches
    - apparently this latest one (from Gaborxx) works

    I have got this firmware but will the remote controller work too? The firmware is for Daewoo TV and mine is Hitachi. VES500QNDT-2D-N41 is my TV screen main and the firmware has got VES500QNDH-N2-N45. Is this compatible?

    "I don’t know what the difference is between the MB170 and the 170E"
    Well, for a start, they might have different processors, and flashing the wrong firmware could ‘brick’ the motherboard
    "That’s why I’m trying to force a firmware update."
    How do you plan to do that???
    "I’ve got the firmware, but will the remote control work as well?"
    "Install it and you’ll find out what works – and what doesn’t."

    Now the only question is how to change the boot logo, because this firmware is for Daewoo and mine is a Hitachi. Does anyone have any idea how to change it?

    Yes, there’s an idea to change the logo,

    According to the service manual, the 17MB185 has one type of processor, but the reality is quite different...

Topic summary

✨ The discussion concerns a Hitachi 50HAK5350 TV with Vestel 17MB170E mainboard and VES500QNDT-2D-N41 panel that is stuck in a bootloop after a suspected failed firmware update. Recovery mode did not solve the issue, so a full recovery firmware was requested. Suggestions included trying service mode/reset procedures, contacting another forum member for firmware help, and checking related MB170/MB170E firmware sources. A firmware from a Daewoo set was eventually flashed successfully; the TV booted and the remote control worked. After recovery, the remaining issue was how to change the boot logo back from Daewoo to Hitachi, but no direct root-based method was available in the thread.
