Need a backup rom with BMM preinstalled
Hello all!, I've accidentally lost my cid.img and my phone only boot up to the known error screen. The phone is on stock retail.BR jelly bean. What I'm looking for it's a rom backup with bmm preinstalled as the tittle said. I'll try to make .img files from the backup and flash those files through fastboot xd. Another question: If I flash the system.img, I need to flash boot.img and radio too?
Any help would be appreciated
Edit: phone: xt-910, stock jelly bean (flashed through rsd)
