How to Install TWRP 2.7 Recovery: TWRP 2.7 works only with the Android 4.4.2 KitKat powered Huawei Ascend P6. You must have installed Android ADB & Fastboot drivers on your PC. Get the Fastboot folder using the guide. Once done with the ADB and Fastboot installation, download TWRP 2.7 Recovery.img file. Rename the downloaded file to boot.img. Enable USB debugging mode on your Huawei Ascend P6 and connect it to your PC. Now open the Fastboot folder that you created using our ADB & Fastboot guide. Press and hold the shift key and then right click on an empty area inside the Fastboot folder, now click on “Open Command Window Here”. Now in command prompt type “adb reboot bootloader”. It should reboot your phone into the bootloader mode, now push this command in command window “fastboot flash boot boot.img” This will quickly flash the TWRP 2.7 recovery in your device. Once done, reboot your device. Boot into recovery by pressing Volume Up or Down Key as soon as you see the Red LED while booting up your phone. You should see the TWRP recovery interface now. That’s all with the recovery installation on the Huawei Ascend P6.
