DCPhoenix and OEMinfo?

[gascat]

ive been working with various devices and generally have success but in some cases im still having issues, DCPhoenix says you can drag and drop your own OEMinfo file to flash but whenever ive tried this i just get an error saying "Not an oeminfo file" is there some sort of conversion i need to do first as i can be 99% sure theyre real, good OEMinfo files. also while attempting to debrick a mate 10 pro that i killed while attempting to downgrade ive noticed that you cant actually modify the region of the oeminfo you select from the list, eg if you select BLA-L09 the device will have C652 (hw demo) no matter what you enter into the boxes, likewise the L29 variant will always remain C605 (hw la)

is there a thread/repo of created oeminfo files anywhere or does anyone know how to convert a standard oeminfo so that it will work with DCPhoenix?

Make sure files that you drag/drop are .img format.
