    OK everything is clear, there is no way the chip to get damaged because of this, you just interrupted the update, and it turned out to be the cause of the issue, but that doesn't mean the chip is already defective.

    The laptop doesn't realy turn on.
    The keyboard illumination and power button briefly turn on, then everything shuts down.

    I'll try to desolder it tomorrow.
    If i get succesfull reads, schould i flash the bios posted in the beginning of this thread?

    Thx for the advice so far
    Oops my mistake - I did not read the whole your first post because of the obviously smaller archive, thought the goal was unlocking but that doesn't change the meaning of what I said, the chip very rarely happens to defect, the much more likely cause of your problems is what I already told you.

    BTW what do you mean by "corrupted in a bad flash" - during the Windows update, or something else?

    isn't the fact it starts reading a sign the spi communication is ok?

    Can the reason be it hangs, it is corrupt?
    No, if it was "corrupt", the laptop wouldn't turn on.
    It's just the crappy chinese clip doesn't make a good contact at some of the chip legs, or/and the cable has become unsoldered on one of the pins (the cable is also thin and crappy), that's why.

    Edit; You have to read the chip, then erase it, then program it with the patched dump, then erase it again and program it again with the original dump. I just don't see how it's going to happen with that crappy clip...

    Maybe it's time to put in my signature - "Do not touch the 25Q80JV chip"
