Now the issue is that I flashed my sister's Acer Aspire 5620's phoenix BIOS to the latest version of 3234.wph, the original BIOS that came installed was 3219.wph version(you may check the BIOS file if required- link). I used the WinPhlash utility to do this. Since updating to the new BIOS, the notebook does not boot to windows and shows the dreaded blinking cursor, it only boots if Load Defaults is selected in BIOS. And this step has to be performed every time to boot, it does not boot during a restart also.
When I tried to rollback to the old BIOS using WinPhlash, it doesn't allow and gives message that the notebook has the latest BIOS version and the old one will not be installed.
So please advise me how to flash the old BIOS file back, maybe using another bootable USB key flash method or how to resolve the blinking cursor scenario in the first place. Of course, I did this update without consulting Acer .
Thanks in advance....
