I tried with parallel port adapter with various program but it doesn't help. I know juuso also tried with some pricey jtag cable with same result. I believe, we need some specific JTAG hw or sw for this board(s).

Hello. I have a similar problem than erdem_us on his first message. My television UE32D6100 was bricked when I tried to downgrade the firmware using 46.101.161.175 as a DNS server IP address (viewtopic.php?f=22&t=4199&start=270#p100850) so I would prefer to repair only the damaged components in the mainboard instead all the entire mainboard. My chips where the corrupt firmware is located are the same than erdem_ua (SDIN502-2G and KFG1GN6W2D).
I've been looking for the Internet and I found other people in a similar situation than me. For example:
https://www.plcforum.it/f/topic/210322- ... nt=1540519
I repeat the same question as before: wouldn't be possible to extract that BGA chip, reprogram it or replace it with another new BGA chip (same model) in order to avoid all the mainboard replacement? I've found firmware dumps in some russian pages like http://tel-spb.ru/remont-tv-lcd/samsung. It seems that these files were extracted using some programmer. In fact I think in other russian forums are talking about this (http://www.kenotrontv.ru/forum for example). The problem is I can't understand (read or write at this momment) in Cyrillic alphabet. Anyone has more information about this possibility please? Thanks in advance.

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.
