For Badcaps Readers, Please note that I am hopefully going to present this same message to Lenovo to see if they have any insight to the matter as well and figured to share the entirety here for clarification. The System is out of warranty as it is but does have the option to have it extended.

Hello!
I'm trying to remove the bios password of an Lenovo ThinkCentre M75q Gen5
Unfortunately i cant find many resources about the Gen5 or the bios chip.
Bios chip is XMC 25RU256CXIQ.
SN is GM0QDZ77
Let me know if there is an issue with the attached bios dump, as this is my first attempt and i dont have a wson8 clip
Would be great if someone could decrypt the password from the dump, but if thats not possible i can attempt to flash the chip (hoping my crappy solder job works)... -
