Upload that software for me, and or show me help/about. It may be OK for that chip, but I am not sure (especially due to next >>)
Please show me image of this BIOS chip, I can't find that ID in google. Unless it's this one >> XM25QH128A << I think so, this is XMC 25QH128A general ID
For that chip, these are only ones I know that work for sure, with ID's as mentioned >>
ASProgrammer and choose W25Q128FV ID, otherwise all writes will fail
Also colibri with ID EN25QH128

And really, we'll never know if that software is OK to read or write, until you dump and then until you write, then close program, open it again, read/verify/save and then compare that file in hex vs what you wrote (if it's a match then it's OK to write to this chip)

Make sure cable is not stretched out, and try to make it slip/pop off least you can, the more that happens the quicker it wears out ability to grab a chip.
The cheap clips only work so many times before the roughness that lets the fingers grab wears down and flattens out, then you can't grab anything.

Yes, hopefully new clip will work better, treat it gently once it arrives. Best clip is Pomona 5250, but it's $15-18 and you have to make your own cables, or use Dupont cables

Tried all the software but although the flashing process was successful, when comparing data after flashing it, it was still identical to the original data i had dumped.

I gave up after a week of trying. Sent it back to Acer. Thank you for the support though. I have sent you a private message with a download link to the software, and should you find it a useful addition, feel free to repost!

Thank you all for the support.
