    Re: Ue55mu6172uxxh, bn94-12438k

    And now try to re-read the contents of this spi flash on the programmer, most likely there will again be FF at the beginning of the dump.

      Yes, lotas, now when I read the binary, its exactly the same, like before your fix. Does it mean something? Is it fixable?

        You correctly need to set the status register (0x88, 0x42)

          Thank you lotas, for keeping helping me. But sadly, it looks like my programmer can not set status registers ( EZP2019+ ). I have to stop now, get better programmer, and then report back.
          For now, thank you a lot for help.

            So, once again, I have to thank you. I got new programmer - XGecu TL866 PLUS - and I can change even status register with it ( my old one, EZP2019+ couldn't do it ). After flashing your foxed dump, TV is working again.

            // if I can ask - how to know, which block protect bit should I set, if I have similar issue in future? I don't repair TVs mainly, but from that few pieces, what I fixed ( with eeprom issue ), I have never changed status register, and it worked anyway.
