1. You have to be in nougat, install the rollback to marshmallow creating on your MicroSD a folder named dload and inside this folder put the UPDATE.app, install with the 3 button combo or from the engineers menu, the change from l09 or 29 to al10 is only secure from android marshmallow..

2. Install the rom B100 with the 3 button combo, if you have an unlocked bootloader it will relock, you must have to unlock the bootloader many times here (2 or 3)..
