Hi! I have a HP Pavilion 14-v066br notebook and would be great to have the Advanced tab unlocked, mainly to change fan speeds and processor voltages.
As the title says, this bios is RSA signed/protected.
I own a CH341A programmer and successfully flashed stock bioses on this notebook but I lack the knowledge to crack the security.
I write this in hope there is someone who wants to take this challenge. All I can do is flash and test the modded bios.
Here is the latest bios from hp: ftp.hp.com/pub/softpaq/sp92501-93000/sp92961.exe (I don't mind if there is a need to use an older version)
Board ID is 02280

Thank you!

Last time i checked...still the so called NEW (2016 up) RSA versions, hadn't have any successful advances on bypass, and its not for lack of testers.

Oh... I didn't realize that only some specific bioses with rsa check could be modded.
Apparently changing uefi varstores is also not possible. Just have to forget about it, unfortunately.

Anyway, thanks for answering!

Does anyone try to patch EC firmware for return success of rsa sure start reading? The firmware itself loads from spi rom on boot. So that’s possibly to bypass.

@Sweet Kitten Sorry for citing you out of nowhere, but can you take a look at this bios?
I am willing to be a tester if it is of your interest.
