    Hi. A recent Bios automatic update was installed to my PC, the install went smooth, but failed on the final restart. It turns on then off. I found on this forum a post by user Simonise, of making folders Hewlett-Packard/BIOS/Current, and I put inside the F0A bios bin and sig files. Is this the right version to flash? Is my 4gb SanDisk Cruzer FAT flash drive compatible? Or is there another method of flashing? Please share your recovery methods here. Thanks!

    No luck with method 1. I kept Hewlett-Packard/BIOS/Current and only renamed 68AZZ.bin to SMC.BIN. Should I rename the efibios.sig file? Or keep it as 68AZZ.sig? Anyway, same results as last time I'm afraid. I don't have a desktop also. Please help, if it is even possible XD

    You are the only one suggesting that method... It seems that these bioses are quite unreliable when it comes to flashing. I have a music cd in the cd drive, but it wont open. Do i need to open it up and remove the cd drive?

    I tried that. Again, 10 seconds and then boot off. Do I need the USB in? I tried both anyway and no.

    (says to use older bios as newer would not recover) best to grab the .bin and .sig from Previous folder as i mentioned.

    if all fails have to desolder chip and program in a programmer then solder back on.
