[GUIDE][BOOTLOADER UNLOCKED]Unlock LG X Power Bootloader

[Thesansee]

Hy guys, I worked with my LG X Power for a few days and I want to share what I found.

Note1: My device is the K220, so the procedure could be different or may not work.
Note2: If you follow this part you will lose all your data and the warranty, so.

You have to install ADB,Fastboot and appropriate drivers. After that follow the instructions:
1- Enable the "Developer options" menu on your phone: navigate to Settings -> About phone -> Software info, then tap the Build number entry seven times
2- Go to Settings -> Developer options, then turn on the "OEM unlocking" option and "USB debugging"
3- Open CMD from the start menu and type adb start-server. Now on your phone will pop up a windows that ask you if you want to allow USB debugging -> tick on “always allow from this computer” and click “ok”
4- Type the following command on cmd:

adb reboot bootloader
fastboot oem unlock

5- Now on the phone you should see a message confirming if you'd like to unlock your bootloader, press power up button to confirm
6- If you can’t unlock the device with the command of point (4), but I reccomend to do in any case, you could type:

fastboot flashing unlock_critical

7- When completed, to check if you are done type “fastboot getvar all” and at the line bootloader unlocked it should be “yes”.
8- Reboot the devide with “fastboot reboot” or long press power button + volume down
9- When boot up it should tell you that an hard reset have to be performed -> do it
10- Join your unlocked bootloader!

With the Europe version LG K220 work fine... I also ported TWRP and I'm building the AOSP from source (The guides will arrive soon). Unlocking the bootloader is the first step :good:
It should work for LGK220TR K220K K220DS K220 K220DSF K220Z K220T K220dsz because the source code is the same.

Just now did....problem is LS755 cannot boot into a bootloader like gsm models.

Simply cant get into any fastboot mode, but thanks for trying.

At the moment I've found only one method to temporary root, but after the reboot process the device will brick and you have to restore it, so it isn't very friendly. There are some problems to gain the root in our device: the bootloader has lz4 compression instead gz, so the systemless root is a bit tricky to apply ( I've tried also Magisk with no success). In second place there are tons of security control that verify if the bootloader has been modified or not (if yes it will not boot).
I'm working to sort out a final solution, but remember: don't try to flash or modify because you will brick the device!! ( I've found a method to unbrick, so I'll write something soon :good: )

Where can I download TWRP for K220?

Where can I download TWRP for K220?

Sorry for the long time, but I've been busy with work. Here you could find the kdz file. When you have downloaded the right version for your device you could follow this guide for porting the recovery. When you have finished the porting you could boot with fastboot temporary and make some change (for example I modified the build.prop). I've tested it with my lg k220 and I finally booted into TWRP.
note: don't try to flash the ported TWRP and don't try to flash root permission, our device use different compression, so it won't work (already tested).

Han podido rootearlo ya?

Yo eh intentado todos los tutoriales que e visto y no e podido :crying:

Any luck building AOSP?

Root via Magisk?

Has anyone tried root with magisk? The beta version 13.6 does not need custom recovery to install because it can be installed via adb

 

[losoollenos]

A mi no me funcionó, hice todos los pasos sin error y me estaba entusiasmando pero mi k220ar no arrancó, daba un aviso de error y se apagaba unos segundos después al intentar bootear.
El bootloader se desbloquea perfecto, yo creo que no debe faltar tanto para el root.....

I am just curious, is unblocking the bootloader necessary, to boot into recovery via adb (without flashing it)? As long as it can be restored to its original state without the bootloader status "relocked", so I won't void my warranty, I can help with testing

From what I read (or understood) it is necessary to unblock whether or not :good:

Hi all. Someone discovered that the LG X Power and the LG Fiesta LTE are the same device, according to the FCC. Can anyone here help us determine if we can use the root method here on that device? Any help would be greatly appreciated!

The Fiesta is with snapdragon ... anyway x power still resists root

Hmm, I see. So for now we must wait...

Great work. I may help testing when TWRP or aosp available.
