NEED BIOS FOR HP EliteBook 840 G5 6050a2945601-mb-a01

[soter]

Seri no 5CG8398HZ3
There was a security code, the leg broke off while disassembling the 256 one, I could not save the software inside, I bought MX25L25635FZ2I-10G instead of eprom and wrote the files by downloading them from the internet, but it does not trigger.
I would be happy if you could help. Thank you.

Can`t see the marking code the IC picture is too blurred. Check if a schematic is available

ic code sic534, base datasheet is for multi phase vrds for computing, graphic card n memory, is stiil work if this ic not present? during update bios is program stored in ssd?, btw thankyou bro

this was burned on a regulator ic i cleared that after this is not turning on after we put it on sleep until i reconnect battery .

Your main bios backup is only 65 bytes ,bad bad bad. Sometimes the endpoint error can be fixed using a patch script https://www.badcaps.net/forum/troubl...security-error

Thank you for your reply,You are right,the bin file is not clean,I tried this file from poste #2 which is clean,now the laptop works showing manufacturing mode ,the fan spins full speed, and late display.and no more security device Problem message.
Any i dea please

Enter the DMI info with HP Bios Config utility BCU and update the bios

Did you check the bios with ME Analyzer before flashing it ? ,i`ll bet the ME firmware was Initialised. The ME firmware should have been cleaned first , there are some guides if you want to have a go at cleaning it yourself https://www.badcaps.net/forum/troubl...22#post1622422
If you`re going to use a bios from any intel machine check first if the ME is Initialised (Dirty) or Configured (Clean)

For the endpoint error try the endpoint patch script at post #2 https://www.badcaps.net/forum/troubl...security-error , it will clear the NVRAM
