[BOUNTY][REQUEST] HP Envy X360 Ryzen 2500U 15-bq2xx BIOS Menu Unlock / TDP increase

[EnumC]

Hello everyone! I encountered some issues with trying to unlock my BIOS file and I would greatly appreciate some help. I was able to change the menu options from "Default" to "User" in AMIBCP and export the flash file. However, I have hit a wall when trying to flash the image. In HP's recovery page, the software refused to flash due to "signature verification failed - Unable to find BIOS signature file". I am not sure on how I can create a valid signature file with the modified image. Next, I tried to use AFUDOS and AFUWIN (5.09.02.1384). Each produced error such as: "Firmware does not have flash support" and "46 - Error: Problem getting flash information". I would greatly appreciate it if anyone can verify my modified image and provide some instructions on how I can get this image flashed to the EEPROM. In addition, my end goal is to be able to potentially increase the TDP and unlock some menu options for memory frequency. If there's an easier way of unlocking TDP, please let me know.

Thank you!
