finallyy successfully got it 2.1, today i tried flashing some other BIOS the pho.rom file that came with the rar that you gave. So i most likely flashed the wrong bios file (508.rom). However, i did have a problem though, the awd873 too at boot didnt work for me for none of the files. So when i tried updating the PHO.ROM using WinFlash, it actually worked and it read it correctly. Boot still shows v5.07 but i dont care much since it says here 2.1. Im gonna try adding the HP certificate and try activating. Thank you !
