LeMax 2 TWRP Recovery and Bootloader Unlock Guide

[Linux User]

You need to have a custom Recovery on your phone if you want to install Custom ROMs. Also you need to have the bootloader unlocked on your device to install a custom recovery. TWRP is such a popular Custom Recovery available for many devices including LeMax 2 which is brought to you by Developer HostZero. This not officially supported by TWRP yet but the developer is going to make it official very soon.

DISCLAIMER:
Installing custom recovery on your device requires the bootloader to be unlocked and may VOID your warranty and may delete all your data. Before proceeding further you may consider backup of your all data. Understand the fact that you are the only person responsible for everything that you do with you device.

If you blame me for the disaster that happened to your device then I will simply laugh at you.

I have a brand new LeEco Le Max 2 (X820) phone. I wanted to root it. Following the directions here, I managed to install TWRP. Here is where I ran into trouble. I was not able to install the superuser program because I was unable to access the internal storage of the phone (internal storage 0MB). For that reason I was not able to back up the current system. I researched the topic, I found out that if I wipe the internal storage, I would have access it. So I wiped internal storage, but now the phone will no longer boot, it is stuck on boot up logo page. I do not have a back up of the existing system. But I am not attached to it. I am happy to migrate to a new version. Any help would be greatly appreciated.

Dear shibaa987:
Thank you for your reply! I feel so relieved you answered. I am completely new at this. I am terrified that I would do something dumb and make things even worse.
Since I can no longer boot into android, how do I transfer ROM onto the phone?

[Linux User]

Hi Ian,

Few question(s):
– Do you have TWRP installed??

If NO then you would need to install the TWRP first on the phone to proceed further.
If YES, then do the following to get it connected to a PC:
– Select Mount and Enable MTP (If you see as Disable MTP on the below right side button then no need to do anything)
– Now connect the phone to a PC (Windows PC is recommended) with a USB cable.
– Now you will see the device’s storage on PC and you can transfer the required files.

I hope you won’t find any difficulties executing the above. Feels free to Send a message if you want any help. :)

Thanks for your reply. Yes I have TWRP installed. That was how I was able to wipe internal storage, resulting in an unbootable phone. I have decided to try LineageOS you recommended. The instructions says to “Wipe data factory reset, Cache partition, Dalvik Cache and Format the System partition.” I am a little concerned with that because wiping internal storage is what got me into trouble in the first place.

As you have already wiped everything off the phone, you should not be concerned of this anymore.
Now you just copy the ROM and GApps file to the phone via TWRP MTP mode and then flash the ROM and GApps and then boot the phone.

It’s that simple. If you still get into trouble I am here to help you out. :)

Thanks, shibaa987! For my education, what can be done with an encrypted phone? Since internal storage is not accessible, there is no way to install a ROM from it. I don’t think push or sideload will work either w/o access to storage. Is the only option available wiping internal storage?

Ok, if the phone’s data partition is encrypted, then you need to format the data partition. Note that format is different than wiping the partition. I believe after formatting the data partition it should be decrypted.
Now, you either copy the ROM file to the storage or do a sideload, and it should work.

Please do let me know after doing that !!

[Linux User]

Thanks! That seems to have worked!
