Download Custom TWRP 2.8.7.0:

https://mega.nz/#!NQg0iaTK!T1ySN6vD8Mpk6f76ms0mK_pELGHrSUuF2-puqUsa-Fs

1) Once downloaded, un-RAR and find filename "recoverye.img".

2) Rename it to "recovery.img".

3) Ignore the "MT6752_Android_scatter.txt" file. You may need this file if you were to flash via SP Flash Tool in the future.

And here is the tough part!!! :eek: Flash "temporary" TWRP via ADB commands (risk is yours):

1) Reboot PC.

2) Repeat disable Windows 8 driver signature check above.

3) Disable any firewalls and anti-virus.

4) Turn on device > goto to Settings > Display > Sleep > change to 10 minutes.

5) Settings > Developer options > ENABLE debug mode.

6) Connect device to PC. Watch the Windows/Desktop taskbar for driver installation, if any. Wait for driver(s) to finish install in the PC.

7) Launch Windows Explorer.

8) Goto directory where you un-RAR the TWRP earlier.

9) "Shift" keyboard + Right-click anywhere > Open Command Window Here

10) In the DOS prompt, type "adb devices". You should get "List of devices attached...(a series of numbers)...Unauthorized (or device)"

11) On the device, enable "Always allow from this computer" > OK.

12) In the DOS prompt, type "adb reboot bootloader". The device now shows tiny "FASTBOOT mode....." text at the bottom left corner.

13) In the DOS prompt, type "fastboot flash recovery recovery.img"

14) In the DOS prompt, you should see "OKAY" status. On the device, you should see "OKAY" status as well.

15) Turn off the device by hold-down Power button for 12 seconds.

16) Disconnect device from PC.

17) Take out the device battery.

18) Wait for 30 seconds. Check the micro-SD card is inserted properly into the slot.

19) Put back battery.

20) Hold "VOL UP" + "POWER" buttons.

21) After you see "Ulefone" logo, release "POWER" button but KEEP holding "VOL UP" button.

22) You should see TWRP screen. If it asked to replace stock recovery, choose "No replacing" option (I'm not sure what is the phrase, but there is a grey box/button to tap). This is important step to ensure in the future, any OTA updates can be done via TWRP.

23) Install SuperSU ZIP.

24) Wipe Data, Cache and Dalvik.

25) Reboot.

26) First time reboot after flashing will take around 10 minutes. So be patient.

27) You can now reboot back to TWRP to do Nandroid backup (highly recommended!).

28) After Nandroid, goto Google PlayStore and install "EFS IMEI Backup" app to backup your IMEIs.

29) Keep all backups in safe place and sleep tight.
