Hi, I need help to unlock bios passwords on two laptops, same model. I tried with hp unlock tool “HPUnlocker.ry”, with “HPUnlocker_v1” and “RCUnlocker_v_1_0” (this is not working with files bigger then 16 mb) without success. Several times checked procedure- no mistake. Using programmer Xgecu T76 PRO. Every time password is still there.

Model is HP Probook 440 G9

1. s/n is 5CD2278SSX, ProdID is 6Q887ES#UUW, MoBo model is DAOX8SM8H1 REV H

1. s/n is 5CD2278SS7, ProdID is same - 6Q887ES#UUW, MoBo model is same - DAOX8SM8H1 REV H

Or, if somebody can give me advice where to find some working...

Well, should write and what happends...Desoldered UC2 and UC6 and all was ok. Conclusion-is not bad contacts, but seems that soldered cannot be readed. Thanks....

I am, several times. And i tried with same programmer and adapter on other laptop (latitude 5420) and all was ok. I know that is the same model, but is not same problem. This was a reason for new threah. Thanks for correcting me....

Hi, dell latitude 5430, mobo LA-L591p, bios ...8FC8, i5 12th gen. On introducing screen, with dell logo is written "secured with dell safebios"
Programmer is xGecu PRO T76, newest software and programmer firmware. I use adapter to read bios chip winbond S25Q256JV (8x6mm) with great success in reading and unlocking with python aplication for previous model latitude 5420.
But...
Now, i try to read bios from UC2 winbond S25Q256JV (8x6mm) with same programmer and same adapter, and programmer is recognized chip as correct model, but as "device ID is 00 00 00 00 00"...
