From your logs from exlink i am pretty sure your NAND has some problems whether boot partitions or kernel possible are unreadable. Thats why tv goes to bootloop.
Hello again. Only the NAND (oneNAND = KFG1GN6W2D) would be damaged?. The eMMC (eMMC = SDIN502-2G) is fine?

Hey,

I have tried yesterday to downgrade my TV

Model: Ps51D6900
firmware: 1025
DNS IP: 46.101.161.175

But somehow it's not working ;( .... also an OTN reset I have performed

Has anybody an advice for me?

PS: Does anybody has the 1016 firmware for the MSTAR model?
Is there a chance to upload it into the board?

Hi,

New here, first ever post

I've tried today, without success, to downgrade the firmware on my TV

TV - UE46D700
Current FW is T-GAPDEUC 1033.2

Instructions from page 1 of this thread followed
DNS set to 46.101.161.175 on TV
OTN is enabled

I've attempted to change the firmware from Menu>Support>Software Upgrade>Online

I get the message No Software to Upgrade Currently

I've tried multiple times and get the same message each time.

Can anyone suggest what I'm doing wrong please?

That's exactly the same I did but my TV got frozen (and bricked) in the third attempt of downloading.

Hello again. It seems I find someone in my country which do technical TV repair service with a working mainboard for a D6100 (his screen is broken but his mainboard is fine). So maybe we can finally do the job. Does anyone know which programmer could be useful with the KFG1GN6W2D chip and where could we fin its datasheet please? I've been looking for it but I wasn't successful. Thanks in advance.
