Guys, i made the flash yesterday with the modified BIOS. Then, my notebook wasnt turing on anymore. So i wanted to fix it with the original BIOS, but then i had a lot of trouble to make it, thats why i want to help for people like me:
First, you have to go to your model name on the original HP web, and download the so called "BIOS Update Unified Extensible Firmware Interface (UEFI)" than, install it, and choose USB option. Now you have your USB prepared. (some people say it has to be at most 2 GB).
Second, you have to download the original BIOS. At that point i ahve to say, that for my model, there are several BIOS option at the HP web, first is the normal bios. (and old versions) But we need the so called : Winflash blbabla Bios, which contain the only BIOS that worked for me. So download it (F.08). Once downloaded, unzip it with WINRAR. Now you have a folder with the original BIOS. Rename the .fd file to .bin.
Third, download the Phonix Mod v.2.11, install it, and aply it to your .bin file. Now you will will have a xxxx.bin.dec file and a RSA.SIG. Copy these two to Current folder of your already prepared USB stick, then rename xxxx.bin.dec to xxxx.bin, and RSA.SIG to xxxxx.SIG (the same as the previous .bin file). Example:
01439.bin.DEC --> 01439.bin
RSA.SIG ----> 01439.SIG
FOURS, unplug everything (batery, power, USBs), then, plug the power cable on, and then the USB stick. Now, turn on your computer, everything should go just FINE
) IT IS NOT NECESARY TO PRESS WIN+B or ANY OTHER BUTTONS (G62 models)
ENJOY YOUR OLD BIOS
