Re: Dell Latitude 3420 Bios Password unlock

The file of the friend Lapfix is perfect, it must have indicated that in addition to the password he also had absolute activated... what programmer are you using?

im using ch341a programmer and the spi chip is a winbond w25r256jv

Re: Dell Latitude 3420 Bios Password unlock

i tried bin file that you unlocked but asprogrammer is freezing/hang-up.
isolated the problem by trying the original bin file and the password unlock only bin file with no problem.

Re: Dell Latitude 3420 Bios Password unlock

@lapfix, sir, is there an option besides desoldering the chip and have it reflash by programmer? if none, then i have to do it all again byflashing with your new uploaded bin file for my bios chip.
