    Hello everyone,


    I am new on this forum and I need he
    lp to resurect my HP 650. Somehow I've flashed wrong BIOS and can't resurect it using USB stick and UEFI.

    HP 650
    Seria
    l number: 5CB2273Y0M
    Insyde bios sticker: B046 (8263)

    I've took apart my
    laptop and found inside Winbond W2580BVSIG and using Willem programmator I've read this flash into .bin (dump attached).

    hxxp://4shared.com/rar/FSeHxdt0ba/w25q80b_orig.html?

    On HP website there is BIOS update but inside this update is bios update but in .fd format and I can't convert it to .bin using Andyp too
    l :////

    It wou
    ld be good if someone can merge new BIOS with mine so I can flash it back to chip :(((

    Thank you

    I've found that phoenixtool can decode version F12 and I've even tried to flash it to chip, but same again.

    Do I need to merge my origina
    l dump from chip to this one and how?

    Thank you

    Tnx urie, quala, mazzif... I've tried all those options but without success.

    I think only hope is to flash dump directly to chip with eeprom programmator but I don't have working dump in .bin format :(

    Tnx

    Tnx redroad.

    I've downloaded dumps and will try it tommorow and I will post results...

    Tell me... do you know, I have 4 files here:

    F35_BID01859_EC.bin (1 MB)
    F35_BID01859_Main.bin (4 MB)

    and

    F35_BID01858_EC.bin (1 MB)
    F35_BID01858_Main.bin (4 MB)

    What is EC and what is Main? What file I should write? Dump from Winbond W2580BVSIG is 1 MB then I guess I should write EC... but what to do with "Main". On motherboard there is one more Winbond flash 25q32BVSIG... maybe I should flash larger one here or...?

    Thank you

    I've found out that EC stands for Embedded Controller and MAIN is BIOS so I guess I have to flash both chips and then both of them will be same version.

    I will post results soon.

    And now everything is ok :D dumps are good... I've flashed main (4MB) to winbond w25q32 and EC (1MB) to winbond w25q80 and laptop is up and running :D

    There is just 1 error message every time I power on laptop like there is no serial number and laptop model but I can continue start up by pressing Enter :).


    Thank you everyone :)
