Root Qiku Q Terra 808 (CP8692_I02), unlock bootloader & flash TWRP recovery

[Zauq]

Hello Friends,

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.

Root Qiku Q Terra 808 (CP8692_I02), unlock bootloader & flash TWRP recovery

I want to change CP8692_I02 to CP8692, because i want up firmware android 6 Chinese Version

You can change the same in buid.prop once you're rooted however you would not just be able to flash and boot Andoird 6 Chinese firmware on your device. I have tried the same but it does not work.

Thanks! It's interesting method, but a little bit risky.

Not at all if you ask me as I have been playing with my device for past 8 months or so. I did hard brick my device at several occasions but was always be able to recover it. During those hard brick the device goes into fastboot mode on it's own or one can press and hold power key & volume up to force the device to go into fastboot mode which it always does.

To recover the device from hard brick it needs to be in fastboot mode whether locked bootloader or unlocked bootloader. If the bootloader is locked then the official tool can flash the stock firmware and boom... The device will be Alive again. Incase of unlocked bootloader it's just the matter of flashing the firmware .imgs through fastboot mode:good: or if you've taken backup in TWRP then just boot TWRP and restore your device.

One warning though... Do not try to flash any other OEM's firmware as I am not sure what would be the outcome as I have only tried our device OEM's firmware. Yes can try porting other custom rom to our device as it only involves flashing system.

I would love to help you but I hard bricked my device about 2 days ago while playing with emmc_appsboot.mbn . As you know to recover the device we need rawprogarm0.xml, patch0.xml etc and the stock rom doesn't contain any of the said files.

Fortunately, I am in touch with another Qiku user and I have already written to him about your requirement. I have also requested to him to respond to you on the xda forum itself. Let's wait for his response.

Besides, I was wondering if you know any ways to get the rawprogram0.xml, patch0.xml etc from a working Qiku for recovering my hard bricked device?? or any other method which can help?. Can Qdart tool help in anyway??.

I have searched Qiku Chinese forum but unable to find the required files.

Any help would be much appreciated :fingers-crossed::fingers-crossed::fingers-crossed: !!

 

[shubhamverma27]

Sure i ll send those files to you in a day or two!

 

[Zauq]

Help! l have qiku terra china after flash qk8692_l02 rom it is boot normal but l reflash to china qk8692_m02 so it not boot, black sreen, no led, only fastboot work. Help me !

You mean you had a device QK8692_M02 and you flashed QK8692_I02 and booted normally but when you tried to go back to your QK8692_M02 it hard bricked??

Well my friend I am afraid but now you need to reflash QK8692_I02 to use the device and you might not be able to go back to your Chinese OS now. There was a similar case where this gentleman from Russia did the same thing to his Chinese Qiku device and he was not able to go back to Chinese OS now. There is something with the QK8692_I02 OS I guess.

I was able to boot v109 of Chinese OS on my QK8692_I02 and the v109 rom & the instructions are there on the given download link. I was in process of being able to use Chinese OS on my QK8692_I02 when I hard bricked my device . Now I need emmc image of Qiku to unbrick it and then I can continue my research and might be able to give solutions to the issue.

Let me know if you could get me that emmc image it would be just 200-300 mb file and the same you can upload it on google drive.

Yes! You can use follow method:
1. Create a new APN
2. If you see on network icon is E not 3G that not support my EFS model(8692_m02) for you. So you can try a qcn file from same model.
