HP 830 G10 Bios Identity Data Recovered while unlocking

[volinakis]

Hi, I need some help with HP EliteBook 830 G10
S/N: 5CG3444X0X
ProdID: 8Z5G7EC
Can't find motherboard ID, SPS is N44544-601

I am trying to unlock it, did all modifications in main bios to put it in MPM mode, after writing new bios at 1st boot it appears a message:
"Bios Identity Data Recovered
The Bios has recovered its identity data from Embedded Controller due to data mismatch"
and it won't start in MPM Mode. Someone please help me to disable this "Bios Identity Data Recovery", I don't have a clue where it is.
Attached main+EC.
Thank you in advance .

I think so, there's no traces of chipsets being desoldered. And it boots ok in windows, with all drivers installed. I will try to downgrade the bios if it allows me (maybe I'm lucky and Bios Rollback is enabled) because I unlocked a x360 830 G10 (basically the same bios platform, V70) but it has v1.04.00 while this one has the newest update, 1.05.21. I see also EC has different versions, I hope it will downgrade EC too.

If somebody has EC bios chipset backup from 830 G10 or 840 G10 please post it here, thank you.

Managed to solve it, found a EC ver. 51.2B.00 which allowed me to enter in MPM Mode. Thank you all for your opinios.

Hi, I need help unlocking this bios. I have tried to patch the main bios based on the x360 version files to put in MPM mode but got the " Identity Data Recovered" message just as volinakis mentioned.
