Brick TV after Firmware Downgrade?

[Trin]

Hello from Germany,

i have an UE46D6500 TV and had the latest T-GASDEUC 1021 firmware running.
So i decided to downgrade the firmware to be able to use SamyGo following this thread: viewtopic.php?f=22&t=4199

So I installed the T-GASDEUC 1013 firmware and now my TV restarts after maybe 30 secends automatically and the RC only responds for a few seconds.
The time is too short to do much, i just managed to do a factory reset but nothing changed.

I also unplugged everything and now i have no idea what i can try.
Is there a way to reinstall the firmware or do i have to call the service and change the mainboard?

Please help
Trin

somtimes this happen, apologies. You can't repair tv at home, if tv under warranty, call service.
