I am trying to read the BIOS chip installed in a Dell Precision 3571 so I can remove the administrator password. Processor is a 12th gen i7. The service tag ID is 7QV7VL3 (8FC8).

So far, I have not been able to read the chip. I have done this a few times on older 8FC8 BIOS chips and have not had a problem. The BIOS chip is an XMC XM25QH256CXIQ (U2502 marked on the board). I am using a T48 (TL866-3G) programmer and a pogo pin probe for the WSON8 chip. The programmer auto ID is identifying the chip correctly but the ID check comes up FF FF FF. It should be 20 40 19. Pin detect is OK....
