basedtechI have posted a thread similar to this, but obvious the flashable framwork version 7.1 keeps on ending up in bootloop.
But no worries cause with this tutorial u can get it installed on Infinix X551 XUI 1N3.1. but you can try this on other device running lollipop 5.1
NB: Doing this is on your own risk, BASEDTECHPORTAL will no be held responsible for
any brick or bootloop.
In order for u to do this, you must have root acces nd custom recovery runing on your mobile.
