Re: Dell Latitude 7400 Bios Password
I downloaded this file for someone else which was a few pages back who was in same situation as me. I have changed the ME region to my extracted one and rebuilt it, am I good to go? if so sweet, if not i'll wait on a patched one...

Re: Dell Latitude 7400 Bios Password
Thanks very much for the tips.
I have now managed to dump UC5, I have attached WSON version and a non WSON version as the programmer software detected multiple, I wasn't sure which too choose so did both.
If possible, could I get the correct one done please? Thanks very much again....Leave a comment:

Re: Dell Latitude 7400 Bios Password
Sorry for another comment, does UC5 need to be removed from the board to be read? spotted there are holes in 4 traces that connect to the 2nd bios, is this maybe the reason software cant detect it? reading other section of bios also?
ThanksLeave a comment:

Re: Dell Latitude 7400 Bios Password
I think my board has 2 bios chips, I read on here UC5 was the one to be read and that is the chip that isn't detected using my programmer and software, any help and advice be great thanks.
EDIT: Managed to dump UC6 and attached, still not able to dump UC5...Last edited by MYWARUK; 08-09-2023, 05:43 PM.Leave a comment:

Re: Dell Latitude 7400 Bios Password
I'm using a TL866ii Plus and using Xgpro v12.60, everything is making a connection, tested with a multimeter, triple checked all connections going to correct pads but the software can't autodetect the chip nor if I select the chip its detected, any suggestions on alternative software? I get "Pins Detected" but checked ID is showing 0x 00 00 00
Chip is a Winbond W25Q64JVIQ
Thanks

Re: Dell Latitude 7400 Bios Password
Hello,
I have been given a Dell 7400 i5 with a locked BIOS password.
I have dumped Mac BIOS's before but I am unsure which one is the eeprom on this motherboard.
Once dumped, what else would be needed please?
Serial number is DYN7733-8FC8
ThanksLeave a comment:
