Hello Friends:cowboy:,

At last I figured out how to unlock bootloader, root & flash TWRP recovery !!

To achieve the above you should have some basic knowledge of adb, fastboot & flashing.

The usual warning... Try the following on your own risk, don't blame me if your device is dead, burnt or you lose your job because your boss couldn't contact you on your dead cell phone :laugh:.

Lets Begin !!

1)	Download & install ADB-setup and Qiku Download Assistant.

2)	Go to bootloader, switch off your phone and press and hold volume up button while connecting usb cable. When you see bootloader press volume up again to enter fastboot mode.

3)	Go to device manager and you should see “Android or unknown” with a yellow exclamation mark under “other device”. You have to manually install fastboot driver here, just google it how to do it. You to have

go to C:\Program Files (x86)\Qiku\adb and select QK_ANDROID_ADB to install drivers.

4)	Unzip the firmwares zip files.

5)	Now to unlock bootloader we have flash the following firmware 6.0.018.P2.160720.QK8692.CPD but we have to force close Qiku flashing tool when flashing is at 1-2%. To do that open task manager on your pc before flashing and end Qiku flashing when the flashing is 1-2%.

6)	Disconnect phone from pc and reconnect while pressing & holding volume up if you see completely black display it means now you have unlocked bootloader. Always refer to the device manager in your pc if your device is in fastboot mode as you would not see anything on the device display once you flashed the above mentioned firmware.

7)	Go to the folder where you have the TWRP custom recovery. While in the folder press shift and right click and select “open command prompt here” from the menu. Copy “fastboot -i 0x1EBF flash recovery Qiku-TWRP-recovery.img” without quotes and paste in the cmd and enter.

8) Once Qiku TWRP recovery is flashed successfully lets boot the same from bootloader. While in the folder press shift and right click and select “open command prompt here” from the menu. Copy “fastboot -i 0x1EBF boot Qiku-TWRP-recovery.img” without quotes. Your device should boot in TWRP recovery.

9)	In the TWRP recovery on your phone go to advance and select adb sideload and start the same.

10)	Go to the folder where you have the SuperSu.zip and open command prompt here. Copy “adb sideload UPDATE-SuperSU-v2.78-20160905010000.zip” paste in the cmd and enter, without quotes.

11)	Now if you wish to lock bootloader again then select reboot option in the recovery and select bootloader. Go to the folder where you have the emmc_appsboot.mbn file and open command prompt here. Copy “fastboot -i 0x1EBF flash aboot emmc_appsboot.mbn” without quotes and paste in the cmd and enter. This will lock the bootloader and you can always unlock the bootloader by following above mentioned instructions.

13)	Copy “fastboot -i 0x1EBF reboot” in cmd and enter. This should reboot you phone.

14)	If everything went well you should see supersu app in the phone. You can also check by an app called root checker from play store if you have successfully rooted your device.

When you have the unlocked bootlader there would be no display when you're in fastboot mode hence you have to check in device manager to ensure that the device is fastboot mode. Plus while booting or rebooting there would not be any boot animation but only the boot sound. This is due to the unlock bootloader.
