Help please!! I just bought a secondhand HP Probook 440 G8 and it has a password in BIOS. What can I do?Comment

Buy an SPI programmer to extract the bios file then use RC unlocker to unlock it.
There are many types of SPI programmers, but the cheapest is CH341A (cheapest but not best ).

Hi. I am trying to unlock the bios password on a 440 G8 laptop using CH341a and needle cable probe (not having to desolder chip) but no success. Seems to have read the chip (EC ROM GD25B256DYIG) correctly but once unlocked with RC Unlock and rewritten, not working. I have also learn that BIOS password is not stored on SPI ROM (Winbond 25Q256JVEQ) but on EC ROM. Please, need some help. Thanks in advance.Comment

I'm requesting a bios .bin for 2 of my hp Probook 450 G3's. Both of which I had forgotten the bios passwords. I stupidly flashed both of them with firmware "made" by the RCUnlocker software and I guess I shouldn't have. The last thing I did was flash both of them with RCUnlocker-fw thinking it would 100% work and left my programmer etc behind and won't have access to them for another 2 days so I figured I'd create a thread to see if I'd be so lucky that someone might have a working file laying around š
Laptop number 1:
Model: HP ProBook 450 G3

Hi, my laptop wont boot at all
With original bios no POST, only LED lights
With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
Some issues
A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
B- If updated from 500LN version 203 to 300, the battery stops being recognized
Things I tried
1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble... -
Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.
Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...
