    I have MX25U12873F and I do exactly what is written above, but software in Step- 3. shows it is already unlocked, but I still can’t erase it.
    When I click read it works (it take 3 minutes), then I follow above steps for unlock, then I click erase and it shows success (it takes 5 seconds), but when I click read again it shows “disconnected”.
    I plug-out CH341A and next plug-in it again into USB and click read, it shows a lot of 00 or FF, but in half of data there starts random symbols like 63, AC, 1D.
    When I chose BIOS file and click write it will work (it takes 4 minutes), but verification shows difference and motherboard won’t start (Gigabyte Aorus X370 Gaming 5).
    I use CH341A with 1.8V adapter and Clip, I checked with multimeter and all pin have connection.
    Can you help ?
