[Solved] JVC LT-55K880 Dump needed - Stuck at a specific channel.

Hello to everybody
I have a JVC LT-55K880 TV (Made by Vestel) , which powers on at HDMI1 but does not respond to any further commands either from the remote or the tv multijog.
SMPS voltages are ok, so I assume that the firmware has corrupted.
Could you please provide me with a working dump file so I can flash it with a programmer (RT809H)?
Thank you in advance.

MODEL: JVC LT-55K880
MAINBOARD: 17MB130S
PANEL: VES550QNDL-2D-N11

Try to program the spi, if it doesn't work the problem could be in the nand

Thank you very much for your reply. I just flashed the board but unfortunately it keeps doing exactly the same as before.
Do you also have the file for the NAND? I could find a working NAND to replace the old one if I also find the file.
Thank you again for your help.

Not at the moment, however I will ask my contacts

Finally I managed to fix the tv for those still interested.
Download and unzip files from this link https://www.dosyaupload.com/kxMK into an empty usb stick, formatted as FAT32.
Put the stick on the tv and plug the tv on the mains while holding the "ok" button of the remote.
After you notice the led blinking quickly release the ok button, and it's a matter of 2 minutes or 3 to boot the new firmware and be back to life.
The only drawback is that this firmware is for vestel, so if you have an other variant e.g. JVC (like me), you will need a new remote.
Enjoy!
P.S. especially thanks to @yokoono from https://tavsiyeforumu.com/ for the firmware
