Hp Probook 450 G7 s# SCD0348W35 had a locked BIOS. Bought BIOS and EC chips off Ebay that were supposed to match this machine - the 450 G7. Flashed in the BIOS on chip i bought using a CH341. BIOS unlocked next boot. Some error to contact HP. Entered BIOS and reset to system defaults and rebooted. Machine worked fine but every cold boot the contact HP message popped and everything else worked as fine. Assumed the error was from EC chip not matching BIOS that i just flashed in. So i flashed in the EC that was supposed to match from the EBay chip i bought and instant brick.

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 😝

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,...
