這個是網友整理得安裝步驟(英文沒很難就不翻了)
* Download new safestrap
* Download ROM
* Download GApps
* Download SuperSU
* Boot into stock ROM/slot.(ps:ss的話確定可以刷在slot1，不想太冒險的比較建議)
* Open up SafeStrap
* Uninstall recovery
* Close SafeStrap
* Uninstall SafeStrap
* Install new Safestrap apk (downloaded earlier)
* Open new SafeStrap (should say 3.75 on bottom-left)
* Install new recovery (very important)
* Once this is done, it should have a button to "Reboot to recovery". Click this.
* After rebooting to recovery, create a new slot (or re-use existing one, your choice).
* Install ROM, Gapps and SuperSU. This will take a while
* Reboot. This will also take a while.
