    Buy this one, maybe you can find it in EU stock too to get it quicker. Never use clamp, it is unsecure, simple wire out from the mainboard to the programmer with short wires, thats all. For future use xou can buy an 1.8V adaptor too (for other EEPROM), itt is cheap also.

    Well, that is cheap! I work daily with electronics so this is kind of a piece of cake. We do have eprommers at work but those are quite old, over 10 years or so.

    PLEASE, report if you try fixing it!

    Here is video of the operation: https://www.youtube.com/watch?v=GLv7jiStHyk

     

    But yes, with wires… Ordered the flasher, now we wait.

     

    But one thing, please tell me that the “jumper.rom” and “JUMPER10x.P8.WP313R.NHNAUHN02.rom” are the same file? I flashed the latter one.

    It is the same, just for easy type at UEFI prompt for flashing. I think no w10 supoort, just W7 x86 or amd64. Use the oldest 1.18 software package, newer are pain in the ass, at least for me never worked other versions.

    Ok, good. Still I don’t get it why it didn’t work… V5 worked with V4 bios but V4.5 laptop failed.

    Maybe another mainboard revision, with programmer you can play with .rom files to find the right one, if you have the original dump to restore if failed.

    Elnec is a great programmer if you can get the updates.

    Wow, never did the wiring so precise 🙂 Maybe the wires are too long, this can disturb the flashing process.

    It reads! And checksum doesn’t match with the “jumper.rom”…

    This is getting exciting!

    And problems… Reading works, erasing works but when I flash then verify fails. So flashing doesn’t work like intended. Maybe too long wires…

    Does not matter, I never do verify beacuse of fail. Erase chip, flash it and should be fine.
