Hi first sorry for my bad english i have a big problem with my hp laptop,my leds are flashing 2x times and the screen is black ,so its the bios failure, i´ve tried everything what i found in this and other forums, but with no success my bios is not uefi so I put all files in root PlatformName=3635 PlatformName2=3636 PlatformName3=3637 PlatformName4=3638 PlatformName5=3639 PlatformName6=363A it works only with 3639.bin, when I take other names it suddenly shutoff, with 3639.bin it beeps 2 times fast and then for a minute all 10 sec , no restart or something else, screen remain black and 2 leds are flashing 2xtimes what I tried: alle platformnames with .fd,.rom,.bin, also A.bin new ram, gpu reflow hope you can help me regards
i believe u have to put files in Hewlett-Packard\Bios\Current and in previous try holding all 4 arrow keys to do recovery
u say its not UEFI yet in diagnostics of the laptops dload page shows UEFI .. it is UEFI but not encrypted
i thought this because of andy´s tool i didn´t get dec and rsa so its uefi but not encrypted, but how to recover it now ?
not sure.. ive never had success with non RSA .. i use .sig file and works. try a 0 in front of numbers on filename. ask hp forums ?
I have connected the hdd to a working computer , found a partition with hp_tools, there is only a hewlettpackard/systemdiags folder with cryptrsa.efi, SystemDiags.sig, SystemDiags.s09, SystemDiags.efi is this helpful ?
thank you for your help, I posted also in hp forum but nobody answers bios chip is a winbond 25x16avsig, should I buy new one ?
they take at least a day to reply, if they even do. u could get a usb spi programmer and try to recover chip by making a backup.bin then we merge bios with a hexeditor and flash fixed.bin to see if it works. or u can try a bios chip from ebay, much easier.. if it works (%10 chance it might not be right bios in chip but they tend to fix the issue with second chip)
thank you for your help !!! bought new bios chip from biox fix and it work now, but I get a error message on startup Product Information not vald The following product Information programmed into the systemboard is missing or invalid Systemboard(00A)-Product Name Product Configuration Product Serial Number Product Number Enter-Continue Start Up how to delete this message ? regards
need DMI tool for that board like NBDMIFIT 1.19 all the info is under battery .. except GUID which is a randomized number/letter or maybe hotswap bios (to change chip while in dos ready to swap and flash) and flash old ?
