hello dear admin, do you know what is the difference between BN41-01660A and this B ? Will it fit?

Honestly I don't know. Sometimes the versions are similar and compatible, but sometimes they are not.

I tried this dump on 3 different NANDs for UE40D5500RW with BN41-01660A main and it's not working
(edited) on by board there is absent ZR1312 resistor. In photo from google I see that it must be.

I set 1k resistor, but there is no changes. Also I looked into photoes, when this TV comes to me from another master and there was no resistor in that position. But I write dump into NAND and TV was working 2 days. After that I get TV back and flashed agin, then I put USB firmware and press upgrade, after that TV is always restating. Could there be a problem with SPI or Onenand?
 That resistor is connected to pin 16 CLE, how TV could worj without it 2 days?
 Also I think SPI is not touched in this chassis during USB flash. About Onenand - I don't know.

Very strange situation, but i think the problem is some sector of memmory with defect.
I cant find other issue after read your feedback.
