[OnePlus 3] Unlock Bootloader, Flash TWRP and Root

OnePlus introduced the all new OnePlus 3 to the world just a few weeks back. The OnePlus 3 is the 4th addition to the OnePlus family and comes with some serious innovations on-board. OnePlus has ditched its previous plastic-sand build and turned the phone into metal giving it a whole new premium look and feel. OnePlus 3 carries a Snapdragon 820 CPU under the hood which is accompanied by a whopping RAM of 6 GB. The internal storage starts from 64 GB which might become a standard for the flagship smartphones of the year 2016 following the footsteps of OnePlus. There is no external card slot in this smartphone, 64 GB of internal storage is quite enough for that matter. OnePlus 3 is powered up with Adreno 530 GPU, which might be a great choice for Android gaming geeks as well.phpnblzg9

    I followed a similar guide without doing t he backup. After installing SuperSU I got stuck whenever I boot up regular into the loading screen. I tried doing a wipe and factory reset but still can’t past it now. I didn’t put the SuperSU into the TWRP folder. Any other suggestions?

    • @slaineded:disqus Flash stock firmware for the time being to fix your device first, and follow the method properly afterwards.
