if you have sigma box or other supported box you can write OEM info using XML flash file or board software
your problem will be fix
if you flash usin OTG its not help because it not change anything in your build number
just flash using test point or write OEM info (UNLOCKED Boot-loader) in fast-boot

dont forget for write OEM info you need XML flash file or Board Software of your phone model
