Why does the chip read reads all FFFFs ,did you erase the chip.What model is your programmer and software version.Are you using a clip.

Thank you for replying, yes I tried to flash it and after it didn't work I tried a few more times, accidentally erased it and the backup got lost on a wipe, careless on my part, After I read it, since it was erased, it showed all FFFFs, I have a I am using AsProgrammer version 2.0.4, I wanted to get another working bios to flash it and have it running as it was before.

Really started now (PW07TSR2) 03.2024 you won't find a BIOS for this unless someone would download something like that from their notebook.
What was the reason for reading the BIOS with this bad CH341A junk?

I bought it from a girl in FB maktplc, she advertised as "it turns on but locked, for spare parts" it was an unlock project, it is locked still, but it will not turn on because I found out , after reading many threads, I screwed with the programming in the PC dontroller chip, I had some free time and I thought it would be a good way to spend it, but project is not going well at all. I guess I have to wait and see if anyone has same model and is willing to upload a dump of the EC chip
