This is for x722 only

Hello, I've made this thread in order to clarify some users and to avoid possible bricks.

Obviously if you have your bootloader unlocked you don't need to unlock it again, you can check like that:
Code:
fastboot oem device-info
Results unlocked should be like that:
Code:
(bootloader) 	Device product name: [le_zl0_whole_netcom]
(bootloader) 	Device tampered: false
[B](bootloader) 	Device unlocked: true[/B]
(bootloader) 	Device critical unlocked: true
(bootloader) 	Charger screen enabled: false
(bootloader) 	Serial console enabled: false
(bootloader) 	Serial hw output enabled: false
(bootloader) 	Display panel:
If you have :
Code:
Device unlocked: false
It means your bootloader is locked ofc

Bootloader unlock

Downgrade to 01D Rom
In some EUI roms you don't have to downgrade to 01D rom, but if you don't know if your rom can be unlocked or if you wanna feel more confortable and to avoid problems, is better to downgrade
-firmware WIXCNFN5802005041S (see Settings > About Phone to confirm whether you're on this firmware or a different one... if you're on a different firmware on 20s, you don't need to downgrade)
-stock 26s (if your x722 came with 26s, you need to downgrade to 01D)

you can find the file here: Download
Basically:
Attetion!!! This update is to be used in the official recovery, TWRP will hard brick, don't flash it with TWRP
  • Put update.zip file inside your sdcard
  • Reboot to recovery
  • Click on install update, and 01D rom will be installed
  • Now you can reboot to fastboot mode and unlock your bootloader
  • In fastboot mode type
    Code:
    fastboot oem unlock-go
    To make sure bootloader is unlocked you can check with:
    Code:
    fastboot oem device-info
  • Now, under "Stock 20S unlocked" folder you'll have a stock rom, cleaned, unlocked and friendly to root, you can intall in fastboot by opening flash.bat

Install TWRP

Please make sure you have bootloader unlocked
  • Download TWRP: Download
  • Put phone in fastboot mode, place twrp image inside your adb folder and type:
    Code:
    fastboot flash recovery twrp-3.2.1-0-zl0.img
    That's it, you can boot directly to twrp by typing:
    Code:
    fastboot boot twrp-3.2.1-0-zl0.img
    You might have to press the 'power' button twice before touch is enabled in TWRP

Root
Please make sure you have twrp installed and bootloader unlocked
  • Download magisk here: Magisk thread
  • Reboot to recovery(twrp)
  • Flash magisk
  • That's it

Things you shouldn't do
  • Don't flash official stock roms with twrp, it will brick your phone (hard brick)
  • Don't flash x720 roms on x722, it will brick too
  • Be careful about the modems you flash, it can mess up with your bands

1. You can unlock the bootloader and flash TWRP on 20s, provided that your ROM firmware isn't WIXCNFN5802005041S, which is the stock 20s ROM, I believe.

2. You cannot unlock the bootloader and flash TWRP on stock 26s. This will cause the bootloader to be permanently locked, and you'll only have access to fastboot mode. The only way to fix your phone would be to use Qualcomm's 9008 mode and a QFIL file for the x722... which doesn't exist.

3. Anyone who downgrades their ROM to the 01D ROM can unlock the bootloader and flash TWRP. It's just that if you're on a vendor 20s ROM, you can do so without having to flash 01D. Some users may flash 01D over their 20s vendor ROM to be safe, but this is not a necessity. The 01D ROM is really only for anyone on LeEco stock ROMs. Which very few of us are on, because third-party sellers almost always load their own ROMs on the x722.

If you not sure about what you doing, ask for help, better than get your phone bricked, cheers

Glad that someone finally made a thread about it! Maybe you should emphasize (like in bold text) that you absolutely should not attempt to flash TWRP on Geekbuying, Gearbest, Banggood, and other vendor ROMs, because a lot of people here don't seem to understand that you absolutely have to flash Batyan's developer ROM first... I sure didn't, lol.

Please help

Build Number is: WIXCNFN5802001232S

5.8.020S

LEX722

When you say to transfer the update.zip to SDCARD, do you mean the internal storage? Any particular folder?

Fastboot not working

EUI VERISON: 5.8.001D (Dev)

BASEBAND VERSION: MPSS.TH.2.0.c1.9.1-00032

3.18.20-perf-g00cf2f0
[email protected] # 1
WED JUN 14 17:23:24 CST 2017

Build Number:
WIXCNFN5800106140D

So, I go into the file (with the phone in fastboot mode) and I double click on the bat file with all of the Chinese symbols and then it just reboots and doesn't give me the option of doing the following:

"In fastboot mode type
Code:
fastboot oem unlock-go
To make sure bootloader is unlocked you can check with:
Code:
fastboot oem device-info"

I'm a bit lost and a very beginner. Could I have some guidance please :)

EDIT: Battery is only at about 20%, think I read somewhere it needs to be a minimum of 70%. Going to let it charge up while I go to bed. I'll try again in the morning and let you know

Well, clearly you don't know how to use fastboot xD
Install fastboot and adb: https://forum.xda-developers.com/showthread.php?t=2588979
Then open cmd and type : cd C://adb
Then: fastboot devices
Then: fastboot oem unlock-go

    same problem, twrp-3.2.1-0-20180108-codeworkx-zl1 won´t work even after 5 trys and wildly pushing the on/off button a lot of times.

    which one workes for you?

    What another? Does it have filename, version?


    Ok, With twrp-3.2.1-0-20180108-codeworkx-zl0.img DIDN'T WORK.


    The version which worked is twrp-3.1.1-0-x2.img, which you can get from here:
    https://forum.xda-developers.com/le.../twrp-recovery-multi-tool-zl0-lex722-t3702703

    Hi peeps. Do you have the below phone stats? If so, you can do what I did to unlock your bootloader, install TWRP & Magisk, and then install the ROM of your choosing. (I installed Paranoid)

    ROM:
    5.8.020s stable
    Android version:
    6.0.1
    Kernel Version:
    3.18.20-perf-g00cf2f0

    Build number:
    wixcnfn5802001232s release keys

    Begin by connecting your phone to the computer in debug USB mode. Then install the driver for your phone if you don't already have it.

    Driver:
    http://adbdriver.com/upload/adbdriver.zip

    Once your phone is recognised, leave it connected to your computer, power it off, then start it up in fastboot mode (vol- and power button)

    We will now unlock fastboot and install TWRP.

    Download this package:
    https://drive.google.com/file/d/1O3B...ew?usp=sharing

    Extract the above package to your desktop. Run the BAT file inside. The file does all the work for you, just read it carefully and it guides you through checking your bootloader and unlocking it if required.

    Once it's unlocked, install TWRP by continuing to follow the instructions in front of you. I used the FIRST option for TWRP - I did not use the 2nd option (called BlueTWRP I think)

    TWRP will be loaded onto your phone. At this point I decided to do a complete phone back up just to be safe.

    You will now install Magisk. Simply download the latest version from:

    https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445

    and place it in the root of your phone.

    Then you will go to INSTALL > and then select the Magisk file. After it was installed I carried out a wipe (cache, dalvik) and then rebooted my phone.

    Now you can go and install your desired ROM.

    I installed Paranoid Android. All I had to do was drag the ROM file to the root of my phone along with my OpenGapps package (http://opengapps.org/ - ARM64, ANDROID 7.1) then boot into TWRP, carry out a factory reset, then flash the rom and then the Gapps, then wipe the cache/dalvik - and finally reboot the phone.

    As you can see, no upgrading or downgrading or any other messing about on MY particular build of phone.

    Good luck!

    But Batyan says



    ???

    https://forum.xda-developers.com/le...ent--and-mods/stock-eui-5-8-20s-x722-t3680624

    In any case, it might be safer to just update to Batyan's ROM instead of doing it from a vendor ROM. What with fake 26s (while showing 5.8.20s) some people are getting on new phones and all.
    Batyan published that because he thought he was presenting the 20S ROM.

    Actually Batyan published a package with two ROMs, a fastboot via 20S that comes in most terminals, and another official one that is 01D, a developer ROM, that does not work well and is good for little, but that has the advantage that being official, can be installed from another official, and that is why it is important, since it can be installed from the stock 26S, and having no problem to unlock the bootloader serves as a bridge.

    Actually if there was another official rom that allowed unlocking bootloader would also serve, only that there is not.

    The rom 01D is not for daily use, and the only reason to install it is to try to unlock the bootloader and not leave you for having an official Rom like the 26S. If you do not have that ROM or the one I mentioned above, it is a waste of time to install 01D.

    Actually you do not run any danger when unlocking the bootloader. It leaves you or does not leave you. The danger is what you do next with an unlocked bootloader (how to install twrp in a 26S Stock).

    By the way, nobody mentions that when unlocking bootloader the data of the telephone is erased, so to make copy before.

    Greetings.

    I can not access the phone's storage from my computer when the phone is in TWRP. That sucks because I want to wipe everything and install some custom rom.

    Tried so many drivers and so forth for the past 2 hours and it still doesn't work
    Some x720 owner had the same issue and solved it by upgrading TWRP. But we only have one TWRP version for the x722...

    OK, I solved it finally. That was a pain in the ass. Windows kept installing Leeco drivers which needed to be deleted first. Only ADB was working properly initially.
    If anyone has the same problem with no MTP in TWRP:

    In the Device Manager select update driver (for the unknown MTP device with yellow exlamation mark). Windows automatically had that "MTP USB Driver" under "Portable Devices". Here is a tutorial:
