You have to dump the second chip (16MB), and use this this dump with RCU.

Hi there!
I got myself with this laptop in a bag in pieces...like a Lego or something...
From the motherboard are missing the two BIOS memories and two mosfets from the input power line.
The mosfets are not a problem...the BIOS chips are...i know the bottom one, near EC chip, is 25Q128JV and the one near RAM is 25Q256JV. Both wson8 package...I have these on other boards...

I have all data on stickers :
Model : HP Probook 650 G4
Prodct ID : 2GN04AV
SN# : 5CG8490STJ

I wish to know if i can bring this laptop to life with brand new virgin dumps and it is someone to make this dumps from scratch...

Thanks!

Test and report

Thanks!
The EC chip content ?
I find content on other threads but my MB serial is different from theirs...mine is 6050A3028501-MB-A01(A1).
Can i wrote that EC in the EC BIOS chip ?

[Mr.Nobody]

Update:
Tried both files and the laptop is not coming on at all...
I use this dump for EC BIOS.
Thank you for your time...
