I TRIED THE DUMP YOU SEND BUT NO DISPLAY BUT I EXTRACT ME FROM IT AND USE WITH MY WORKING DUMP AND NOW DISPLAY IS ON AND SURFACE LOGO IS SHOWING WITH A YELLOW BAND ON TOP OF DISPLAY NOT BOOTING AND NOT GOING UEFI SETTINGS. All file to sait no work....
Greetings everyone... I'm new to the forum, however I took the time to read the entire thread to avoid asking unnecessary questions. I did a UEFI dump with the intention of unlocking the password and after getting help on another forum this happened: After flashing the new file it never turns on again, then re flash original file and it doesn't turn on either. Definitely the problem is not the IC, it's good, neither is the soldering. You might think it was a bad copy even though you did it with three different programs and they were all the same. The flash was done with AsProgrammer_2.0.3a from CH341A with 3.3 Volt mod since CH341A Programm and NeoProgrammer couldn't unlock the write or maybe I didn't know how with those. SP4/1724 / W25Q128 - I5/8Gb/128Gb Any suggestions that might help would be welcome?
Ch341 programmer is the cheaper and time to time have problem to read/write bios chip did you unsolder chip form motherboard and read it? or did you read it with clip? did you verify after you read it?
Greetings and thanks for answering... 1- Ch341 is the only thing available to me unfortunately. 2- First unsolder chip, then read and write. 3- I verify with the three programs mentioned above before to compare the copy with the original and after flash the new and compare.
