this is a little after the fact but i was wondering if it's something i should be concerned about using one of those cheap $10-$15 CH341a SOIC8 spi programmers found on amazon to flash a 3.3v bios chip?
the programmer is advertised as 3.3v but actually show as 5v on a meter. i only ask because recently i used one to pull my legion 5i laptop bios > mod > flash back to rom, the first time i did this worked no problem but when i went to do it again a day later after some changes the laptop wouldnt post (just power light on 5-10 seconds and then off 5-10 seconds and on an infinite loop until battery is pulled).
so i tried again but noticed the SPI programmer also didnt work (on any chip), this has me thinking both the programmer and the laptop stopped working at the same time. i ordered a new functioning programmer+clip but even my original bios backup will not boot, same power loop issue. the flash finishes and verifies
