Yotaphone 2 Upgrade

This is the Yotaphone 2 YD206 with Qualcomm Snapdragon 801 CPU, 2GB Ram & 32GB Rom, 3G UMTS & 4G LTE, 2.4GHz & 5GHz Wifi, NFC, Q2 Quick Charge & Qi Wireless Charge. It has two screens: a 5 inch full HD amoled and a 4,7 inch always on e-ink screen.

I’ve upgraded the YD206 Android 4.4.3 to a YD201 with Android 5.0 by unlocking the phone, and use Yotaflasher to flash the latest Android Lollipop version RU1.1.134 and radio firmware S01_003_3034_CN1_M05.

Also tried Marshmallow 6.0.1, but the EPD looked washed out and battery life sucked, so  reverted to the Lollipop 5.0 again. 

Improved battery life by installing TWRP, rooting the phone and installing SuperUserSU so I could install No Frills CPU Control to set Min speed to 300Mhz, Max speed 1267 MHz with a Conservative Governor. Finally installed Greenify with root acces to doze every app that should sleep.
