1) Flash Patched File
2) First boot will delay a few minutes
3) IMPORTANT: Go to BIOS F10 Setup and reset to Factory Default (first main page tab)
4) Restart and enter BIOS
5) 2nd boot restore security settings to defaults

Hello every one in BADCAPS.
Here is a solution to unlock Elitebook 840 G9 :
*Make a backup of your BIOS (main).
*Flash ROM circuit with unlocked BIOS of an other 840 G9 (same motherboard model, in my case 6050A3417601-MB-A01)

*If you have problems (MPM, late boot...) flash ROM circuit with your backup.
*Enjoy

I spent the last few days trying to unlock it! However, when I tried to remove the EC bios, I messed everything up! Some resistors moved out of place and I'm not sure about their position and their values.
Could a friend of mine send me a photo of this area (photo below) and, if possible, the value of the resistors in red.
Thank you in advance for your help!!
