Dear Blaze Tech and others

I broke my W25Q256JV bios (phisically) from HP EliteBook 840 G5 6050a2945601-mb-a01
May I ask for BIOS for serial number 5CG013DSCM ProdID 2FA66AV please?

I tried adjust bios bymyself to change Serial Number with HEX but still I have issue CPU fan spins at maximum speed.

hello everyone, mistakenly i have read the main bios instead EC chip. now my laptop is working but keyboard is not working properly i think because of the main bios corruption. can someone send me the original main bios file for W25Q256JVEQ chip? in this model EC chip is located under the motherboard which is 128MB chip. in 256MB does not include security things like bios passwords and all. bios password i removed successfully from the 128MB chip by searching active on hxd file but after that also keyboard is not working properly and when i use with bios password it worked very well.i tried to reprogram with the backup that i mistakenly read for 256MB but the issue still appears. maybe i have not read it properly. unfortunately here i can not upload the attachments it says i am not allowed to attach bin file extensions. S/N 5CG922701G PROD ID 2FA66AV. i connected external usb keyboard also but issue persisits. please help me with it. thanks

For those who need a clean BIOS (no passwords, factory defaults, without DMI) for the HP EliteBook 840 G5 (6050A2945601-MB-A01):

Since nobody here could help me, I turned to Wrong Chip on YouTube (link below). Here's my experience for others facing similar issues:

1. These BIOS files work—I successfully flashed both by CH341A (modded from 5V for 3.3V!) by Neoprogrammer on Windows:
   • 32MB chip (W25Q256JVEIQ)
   • 16MB chip (W25Q128JVPQ)
2. My W25Q256JVEIQ BIOS was corrupted (physical damagel). You can use my files, but they do NOT include DMI data (you have mine attached for serial 5CG013DSCM)
3. DMI Solution: Wrong Chip provided my DMI data, which I injected using the method shown in this video:
   • HP Manufacturing Program Mode | WHY it Happens & How to LOCK it
     https://www.youtube.com/watch?v=ucZ-nn1aEt0
4. Boot Failure? Another reason my laptop wouldn't turn on was accidentally removing the 22-ohm resistor. If your motherboard is unresponsive, double-check all resistors!

Reupload 2x missed packages to flash as new BIOS
