I have still allways the same Problem with rooing from my P8 lite. I got today a new update with EMUI 4.03. After the update I got the message that my phone is rooted and it is dangerous. Root checker basic shows the message "Sorry! Root access is not proberly installrd on this device" SuperSU shows the message "Root undetected" Phone does not boot past Huawei logo, I get a black screen and then after a minute or so it reboots; Pretty odd, since I've done this on two other phones of the same model and the process worked without any issues. TWRP 2.8.7 does not boot on the phone (black screen and reboot to Huawei logo) TWRP 3.0.2 does boot. Press and hold the Volume Up and Power buttons simultaneously for about 10 seconds. 3. When the Huawei logo appears on the screen, release the buttons. 4. You should now see the Rescue Mode menu. Use the Volume Up and Volume Down buttons to navigate, and the Power button to select. 5. Choose the “Wipe data/factory reset” option. U5kG.
