    Hello, this morning I had to upgrade my BIOS to the latest one but I found out that I was viewing a different model. Now when I bootup my laptop, all I see is a black screen with a flashing white line.

    How can I recover from this error? I've been trying out several "Crisis Recovery Methods" but they don't work. I've used all key combos for boot-block but only Winkey+B makes three beeps. Maybe I'm doing something wrong? I put the right BIOS.wph in there too. I also did a CMOS reset and nothing happened. I bought a $41.99 external usb floppy drive because of this!

    Can someone help me recover my dv2745se pavillion? My warranty has expired already. :(

    I unscrewed the HD cover and unplugged the CMOS battery and left it there for 20 minutes and plugged it back in.

    I tried your method #1 on how to recover and it didn't work. I've downloaded another phlash and another script and it still didn't work. I run the script and it formats my floppy. I plug it in my laptop and power it up while holding Winkey+B and it beeps 1 long and 2 short and then the floppy drive reads again and stops. I wait a few minutes and nothing happens. One method I tried had different beeps, 1 long and 2 "high-pitched" beeps but nothing happened still.

    Which version of Emergency Crisis Tool are you using?

    In my case, I download it from here

    The size of your bios is 1 MB, please make sure you have the correct one.
    Win + B also work for my model.

    @rief: Thank you very much! The link you provided works great! :D I ran the script, plugged in my floppy, held the buttons, and it started up with 1 long and 2 short beeps again and then it became high pitched beeps and after about three minutes it works. :D

    This is for my reference incase anything like this happens to me but when you power on the laptop and hit Win+B, did you take your battery out?

    Do you actually see the menus for Phlash? or was it just a blank screen as the flashing proceeded?
