Hey,
i downgraded my ue40d6500 from 1021.1 to 1013.7.
downgrade was okay. but after restart my tv reboot all the time. every 10 secounds. i had programms and watch tv. but it reboots after that downgrade all the time. so i can't do anything. what happend? did i bricked my tv?

hope you can help and maybe have a solution for me.

is there a way to upgrade firmware without to turn on tv?

best regards

edit: so i have reboot loop after downgrade

Yes, your downgrade went not fine and i think your TV needs to be transported to Service for mainboard replacement... I hope it is still under warranty.
Nothing to be done at home by yourself.

Apologies.

yes it is still under warranty.

but i don't know what went wrong. i could start the tv and watch tv... but just 6 or 7 secounds and then the reboot starts...
is there no way to flash back old firmware or something? or flasing firmware via pc?

None can guarranty the online upgrade function of samsung TV is not buggy. It is! And this is why such problems are covered by warranty.

No, here is no known method to get your TV alive using software way. Theoretically - jtag might help, practically - we are almost on zero knowledge about jtaging samsung tv`s. Just only mainboard replacement.

okay. thank you for your support.
so i will contact samsung now. hope they will not ask why i have such an old firmware.

Will report back what they did.

Best regards
