选择

n2g47o

然后要准备的东西有

1.上面的系统包

2.twrp

3.supersu

下载解压完成后，进入bootloader，然后./flash-all.sh

adb push SR5-SuperSU-v2.82-SR5-20171001224502.zip /sdcard

adb push de.robv.android.xposed.installer_3.1.5-43_minAPI15\(nodpi\)_apkmirror.com.apk /sdcard/Download/

adb reboot bootloader

fastboot flash recovery twrp-3.3.0-0-bullhead.img

然后如果失败的话就在本地进行fastboot替换就可以了。

然后再常规刷入即可。

# settings put global ntp_server 1.hk.pool.ntp.org
