Hi, have you got working finally? I have the same elitebook and looking for a patch.
Hi! I have 840 G2. Same bios version M71_1.31
The goal is the same - to improve bios with NVMe support. But when i flash modded bios , it gives me 502 error - checksum is bad and automaticaly launches Bios Recovery.
Can anyone help me at least successfully flash the bios?
Is there any information of guides about generation of checksums/flashing HP BIOS and so on?
