Alcatel Pixi 4 (4)(5)(5.5)(6)Unlock Bootloader, Root & TWRP 3.0.2-0

DISCLAIMER:

Rooting your phone and using custom Recoveries and ROM's have risks and may result in bricking your device, and has nothing to do with Google or the device manufacturers. In case of any mishap I am not responsible if you brick/ruin your phone in any way.

Basic computer skills are required and minimal knowledge about the phone and phone utilities also.

Make sure that whatever you do, you are doing it at your own responsibility.

Requirements

ADB/Fastboot drivers (Install system wide)

Backed up contacts, apps or any other personal information. I recommend Super Backup

Windows PC, not tested on Linux but should work too.

All files in the attachment below respective to your device. They are not flashable zips, extract them to get your files.

TWRP Pixi 4 (6)- Here

TWRP Pixi 4 (5)- Here

Unlocking Bootloader

- Power on device and boot into Android.

- Connect the device to PC through cable.

- Go to settings -> about phone -> hit 7-8 times on "build number", congrats, you're now a developer!

- Go to settings -> developer options -> hit USB debugging and press OK on the popup window. If the connection is working, one more popup is going to appear asking you to allow the connection, Tick the box "always allow from this computer" and press OK.

- Enable OEM unlocking also located in developer options.

- Open the command prompt window and check if the device is working properly by typing "adb devices". The serial number of your device should appear, so everything is OK!

- Now, boot into fastboot typing "adb reboot bootloader". The device is going to reboot and boot into fastboot mode, waiting for command.

- For the bootloader to be unlocked, you have to type "fastboot oem unlock". A warning message regarding bootloader unlocking should appear on the device, waiting for an answer. Press the volume+ key and the bootloader is now unlocked! WARNING! ALL DATA ON THE DEVICE IS GONNA BE WIPED, so backup your files before.

- Wait for the wiping of the device to be finished and then you're ready to install the twrp custom recovery!

Flashing TWRP 3.0.2-0

Specific Root for Pixi 4 Plus Power (5023)

For the Pixi 4 Plus Power (5023), you cannot flash the recovery using the commands below, you have to first boot the recovery with fastboot boot twrp-3.0.3-0-5023.img. Then make a backup of ALL your partitions then you root with this SuperSU. After rooting, reboot to the system and install a root explorer and go to the system partition and remove this file "recovery-from-boot.p". Copy the TWRP recovery (see attached post) to your sdcard/external, install flashify and flash the twrp-3.0.3-0-5023.img to get permanent root.

- We must be in fastboot mode once again. You can either boot holding power button & vol down while the device is powered off, or type the command in the adb terminal "adb reboot-bootloader" while the device is connected to PC and is booted into Android.

- Assuming that you are in fastboot mode and the device is connected to the PC, you open an adb terminal and type "fastboot flash recovery recovery.img". Because fastboot is installed system wide you can open a command window from where ever the recovery.img is located and flash it.

- Congrats! You now have your twrp custom recovery installed.

- Now if you would like to make a FULL TWRP backup before rooting then kindly do so now, no turning back after this :silly: .

Rooting with phh's SuperUser

- Download the zip file from here and copy it your internal storage or external storage.

- Reboot to TWRP recovery via vol up and power or typing "adb reboot recovery" in the command window.

- Go to Install, then find where you placed the superuser.zip file, tap on it then swipe to flash it.

- Reboot your device then install this app. Enjoy root :D
