Dell Latitude 7400 Bios Password

[rex98]

Hello can you help me unlock my bios password for Dell Latitude 7400.

item number:BBTHK13-8FC8

1st boot, press F2, write service tag, disable Absolute, save (Apply changes), restart. 2nd boot press Alt+F to exit manufacturing mode.

Hello!

My machine is in manufacturing mode. I enter the service tag, but it does not record it. Alt+f does not exit manufacturing mode. The service tag field is empty every time it is switched on!

Since I looked at the file W25Q256JV@WSON8_unlocked.bin you made a mistake with the offset address.
00048900 = 2400 FCAA 5900 0000 0000 00FF 35B2 2AA6
00048900 = 2400 FCAA 0000 0000 0000 00FF 35B2 2AA6
Instead of FCAA 59 you changed FCAA 59 to FCAA 00.
You changed the 59 to 00 that would explain your problem.

Re: Dell Latitude 7400 Bios Password



Only flash this file. In the first boot , you have to go into bios setting for disable all the security options , avoid activate " Computrace " and " Absolute " features.
