Sir… in which post of yours from last 7 days, did you mentioned or asked for any file/tool linked to the forum past user Lost_N_BIOS Guru (Retired) ???
I only see a request for a similar adapter for Asus like the one linked for MSI header…
Care to explain the post #774
Now regarding your flash attempts, verification is not done with the app/device… JFYI…
Desolder the IC and check it outside the PCB, if still fails it may be damaged.
Just an update.
I fixed the x370 pro.
I used a dump of another x370 pro, edited the dump with the only data I could retrieve from my sticker (the MAC address), and flashed with external programmer.
Next time before doing anything I need to save the bios first.
