I have an ideapad 3 14II05 81WD with a system password lock , I can still use the laptop OS (win 11) but I was planning on using USB boot for linux and recovery …
This video below shows an Idea pad (8th Gen Intel ) System BIOS password being decrypted from a BIOS dump https://www.youtube.com/watch?v=IhRw7ePhLKs. I was hoping the same process would apply with my Ideapad, unless someone has a better idea?
In theory then, I need to dump the BIOS , then decrypt the system BIOS password via Hex Reader … I do have a CH314 SPI reader … Though I wondered if doable via software …
I have used Intel FPT before with Skylake Coffeetime Bios Mod , so I revisited the guide here [Help] How to dump bios to file - #2 by Lost_N_BIOS
I understand the FPT version needs to match the ME version for the laptop . So I downloaded the relevant FPT included in the ME tools ( version 13 as the ideapad Me Version 13.0 xxxxx rev something )something)
However when running the FTP tool ‘FPTw.exe -bios -d biosreg.bin’ I am getting ‘Error 51 Could not access PCI device’ ’ Error 64: Failed to initialize SPI interface.’
I had tried the 64 Bit version , but I get the same error …
Can anyone suggest anything else to try before I de-solder the BIOS chip ?
TIA
