[Android General] acartix:
Finally got root on the Pixi4-4034

Hi everyone,

yeah I finally managed to root the alcatel Pixi 4-4 (4034) (3G MODEL). It was really tricky and there are quite some issues you have to deal with.

Therefore please read carefully my instructions and remember I am not responsible for any inconvenience, do it at your own risk.

First of all you have to unlock the bootloader and here comes the first problem. On the Pixi4 this operation leads to a sotfbick because the unlocking process deletes completely the data-partition. The phone can't boot anymore and ends in a bootloop.

To resolve this problem you must reflash the phone with SP-Flash-Tool. After reflashing the bootloader remains unlocked so that you should be able to continue with the rooting process. The second problem is that I could find only one working ROM for flashing. It is for the 4034X, my phone was a 4034D (dual SIM), after flashing I had an 4034X what means that my Pixi became a single-SIM phone, I can live with that.

Here are the necessary steps to obtain root on the Pixi4

1. UNLOCKING BOOTLOADER

- Go to settings -> about phone -> hit many times on "build number" till developer message appears

- Enable "OEM unlocking" located in developer options.

- Switch also "USB debugging" on

- Open the command prompt window (cmd)

- Connect the phone to the PC

- Boot into fastboot-mode by typing "adb reboot bootloader"

- Confirm the debug authorization window on the phone, check "always allow from this computer" (afterwards phone should boot into fastboot, otherwise retype the command above)

- Unlock bootloader by typing "fastboot oem unlock"

WARNING: this deletes the data-partition leading in a softbrick and bootloop,

you have to reflash the phone afterwards to continue rooting!

- Confirm the unlocking with the volume-up key

2. REFLASHING THE PHONE

- I found only this working firmware for the 4034X on this page like described by jh3141:

- You have also to use the scatter file described by jh3141

- After loading the scatter-file in SP-Flash-Tool you have to link the missing img-files in the SP-Flash-Tool-Window

- If you flash the 4034X firmware over an 4034D you will end in a single-SIM phone instead of a dual-SIM.

- After flashing the phone will boot again so that you can continue with flashing the twrp-img.

3. ROOTING THE PHONE

- To root the phone you have to install the twrp-image, the one for the Pixi 4034 you find it here:

- Download and untar the file at the bottom of the page: twrp-3.1.0-0-4034.tar

- Open the command prompt window (cmd)

- Connect the phone to the PC

- Boot into fastboot-mode by typing "adb reboot bootloader"

- Flash twrp by typing "fastboot flash recovery twrp-3.1.0-0-4034.img"

- Download Super-SU "SR1-SuperSU-v2.78-SR1-20160915123031.zip" from

https://download.chainfire.eu/1003/SuperSU/

and put the zip-file on the phone (external or internal storage)

- With the phone switched off boot into twrp by holding power and volume-up keys togehter

- In twrp go to "Advanced" -> "Terminal" -> Type the following code:

echo "SYSTEMLESS=true" > /data/.supersu

- Go back and choose "Install" -> flash the Super-Su-file (SR1-SuperSU-v2.78-SR1-20160915123031.zip)

- Reboot and you’re done, you have root and super-su on the PIXI4

- If you want to uninstall system-apps proceed to the next step.

4. UNINSTALLING BLOADWARE APPS

- You can’t uninstall system-apps directly from the Android-OS,

if you delete the apps with some uninstall-tools it’s strange but the phone will reinstall them after a reboot.

- To succeed you must uninstall the apps in twrp

- Be careful, uninstalling the wrong apps will end in a bootloop or bootfreeze and you will have to reflash the phone starting at step 2.

- Boot into twrp -> go to "Mount" -> check "System" -> go back and choose "Advanced" -> "File Manager"

- In file-manager navigate to the appropriate app-folders and delete the .apk-files

- IMPORTANT: before rebooting you have to wipe the dalvik-cache

- Go to "Wipe" -> "Advanced Wipe" -> CHECK ONLY "Dalvik / ART Cache"

- Confirm wipe and reboot

I personally like the Pixi4-4034, it’s a very small one that is very useful as second phone especially on holidays :).

Have fun.
