Re: Dell Latitude 5420 Bios Password 8FC8

try. 1st screen press F2, disable Absolute, save (Apply), restart. 2nd time write service tag, save, restart, then press Alt+L to exit Manufacturing. For me worked this way.

Worked! Thank you very much!

What model is your programmer ? ,a CH341A (and what software version) or EZP**** , and are you using a clip ,a pogo pin adapter or have you desoldered the chip

i use As Programmer, because i found SPI (WINBOND W25R256JV) only in this programmer. i use a clip.

The chip is WSON 8x6 ,the clips only work with SOP8 chips. You will damage the chip using the clip. Solder wires to the solder blobs or gold pads.Your other options are to buy a WSON pogo adapter or desolder the chip and solder it on an adapter board.
