LeEco X820 Max 2 Unbrick Guide


LeEco Max 2, might be the best buy for the money you spend, just above 200$ you get a Snapdragon 820 power house under a 5.7″ 2K screen in a very well crafted metal unibody. 4GB Ram is more than enough for all of us. LeEco’s bootloaders are easy to unlock and beeing a popular phone there are many developers who are developing or porting custom roms. Here we open the door to custom rom world. To be able to flash a custom rom ( or even a stock rom, we will do it in this guide) we need a custom recovery first and that custom recovery is Twrp mostly. These things are not so hard on paper if you are an experienced user. You just need to read carefully all the steps and use right files of course. What if something goes wrong ? You can end up with a hard bricked phone in your hands that can’t boot anymore, no sign of life. Why ? Because you messed up your phones boot partitions or its partition table. That failure can only be fixed if you have service rom of your model. I mentioned in my Xiaomi unbrick guide, for some models these roms are very easy to find, all “fastboot” roms for Qualcomm Xiaomi models are also service roms with all necessary key files to unbrick in them. For phones like LeEco Snapdragon models that service roms leak after a couple of months. Today we will learn how to unbrick/rescue our dead LeEco Max 2 X820’s that we finally have service rom in our hands.

Files to download :

  1. Max 2 Service Rom (don’t unzip)
  2. Flash Software
  3. Qualcomm Drivers

We won’t be using Qfil Qualcomm flasher this time, we will use a program called “FlashOne1.9”, i don’t know the developer of this software but a very big thanks to him that it makes flashing much easier than Qfil, it still uses inbuilt Qfil of course but with less clicks and easier GUI.


This rescue operation is not only for hard bricked Max 2’s, you can use this method to return o a stock “unlocked” developer rom too, your phone is booting but stuck at the logo or for any situation that you want to fix. Thanks to LeEco we can open our service/EDL port very easily with a key combination (even dead brick). Just press volume + and volume – buttons together while powering up, phone will get into EDL mode. After that step 1 is to install our Qualcomm QDLoader 9008 driver, its a signed driver so no need to disable driver signature of Windows OS. Just double click driver package,


choose WWAN or ETHERNET in this window, it’s not important which one to select, and finish the installation. You should see your Qualcomm QDLoader 9008/EDL (emergency download) port after under “ports” tab in your device manager. It is COM27 in my example.




Unzip FlashOne 1.9 file that you have downloaded, anywhere you want and double click “main.exe” inside the folder. First, choose  “Qualcomm – flash dead phone” from the drop down menu next to “Flash type”.


Then click “Refresh button” next to “Select Device”, your 9008 port will show up.


Next we will browse for our Qfil/service rom by clicking “Select File” and choose the rom file you have downloaded before, no need to unzip it, flasher will do it.


After everything is set up under “Settings” we are ready to click “Flash” button.


After you click flash button FlashOne will start to unzip the rom, this will take minimum 10 minutes or more depending on your PC’s power, so you are free to go and make a coffee in between, or your cup of earl grey if you are a tea guy like me 🙂

flashing2After decompressing is done actual flash procedure will start.


errorIf you get an error like this, just put your phone into EDL mode again pressing both volume buttons and power button  (hear the USB unplug and plugged sound), then click flash button again, choose “not to unzip” the rom file this time because it’s already done.


Done ! Wait for about 10-15 seconds after you see this message, if your x820 won’t powers itself and reboots do as the message, long press power button to reboot it manually.

Your Max 2 will boot with a developer version of EUI, with an unlocked bootloader.



After your phone boots, you will see that its storage is abnormally 9.71 GB, to fix this just factory reset your phone choosing the option “Format Virtual SD card”. File system will be restored to normal values.

STEP 4: (Optional)


“Official TWRP 3.0.2-0 for LeEco Max 2 x820” , download this custom recovery and Snoop05’s “adb setup“. Install adb and fastboot to your system if you haven’t done it before, choosing “Yes” in every step including “install device drivers” too.

Put your Max 2 into fastboot mode while pressing volume “-“ and powering up.

Unzip twrp to any folder you want, go to that folder, right click holding down “Shift” key on your keyboard and choose “Open command window here“. Type :

fastboot flash recovery twrp-3.0.2-0-x2.img  (copy from here and paste to command window > right click > paste )


and press enter. Reboot your phone into recovery while pressing volume “+” button and long pressing power button till it reboots. You will see TWRP screen, thick “Never show this screen during boot again” and “Swipe to Allow Modifications”. That’s all folks. You are ready to flash any stock or custom rom to your LeEco Max 2 now. Here is the latest 5.8.019S (Stable) official rom, its multilanguage and Google preinstalled. See you in the next guide.

Hello friend, I thank you for your prompt response. however just to give you more information attached the legend that comes out in the flash program. just at the end, and this is repeated on many occasions:

11:17:47: INFO: NOTE: There were WARNINGS!! Repeated here, but please see log for more detail
You provided a contents.xml which specified ‘E:\backup_datos_cel_stefany\LeMax2_x820_QFIL_androidbrick\.\devcfg.mbn’
However searching through –search_paths found ‘E:\backup_datos_cel_stefany\LeMax2_x820_QFIL_androidbrick\devcfg.mbn’
This is a FEATURE to allow you to override contents.xml mappings
If you DID NOT WANT THIS behavior, use –forcecontentsxmlpaths

I’m sure it’s a software problem, since one day it was stopped for a while and then restarted and stuck in the logo. and then in the attempt to turn it on, without wanting to get me into mode Hs-usbQDloader9008

Hi friend. I know there are many things to do, but you think you can help a young man desperate to recover his Leeco Le Max2 ….

I explain my situation:
about 2 days ago my cell phone went out and did not fire anymore, I followed your tutorial to the letter, but after FlashOne finished its process, my phone still did not turn on.
I would greatly appreciate your help, because I do not know what to do anymore.

Merhaba Osman bey,
ROM dosyasını flashlayamıyorum, manifest.xml dosyasının eksik olduğuna dair bir mesaj çıkıyor. FlashOne 1.9 ve 2.0 sürümleriyle ayrı ayrı denedim, değişmedi. ROM dosyasını 2 defa indirdim ve indirdikten sonra da winrar ile kontrol ettiğimde ve FlashOne klasörü içindeki decompress edilmiş klasörde de gerçekten böyle bir dosya olmadığını gördüm. Ne yapmalıyım?

Hi first I would like to thank you for your work that has saved many users, according to I would like to ask for help to save brick LEX722, we know that the device is SN820, today there is an X720 that theoretically works for x722 but in practice it does not work, you could edit the files so that it works in this model if it can save many X722

Hi. I have a Leeco Le Pro 3 X722 (Elite) totally like a brick when mistakenly installing a rom for Le Pro 3 X720. It does not turn on in any way and the pc, windows 10 Pro, only recognizes it in the device manager, in Ports (COM and LPT), like Qualcomm HS-USB QDLoader 9008 (COM4) and in no other place. I’ve been looking for a solution for a few days but unfortunately I can not find anything that suits me.
I need help.
Thank you.

Leeco Ben% 1 ulaşır yanıp zaman benim maksimum 2 onu x829 olur ve hücre yeniden soruyor, ne çalışması için ne yapabilirim?

ahmet kaptanoğlu

Merhaba. Le max2 x829 model cihaza sahibim. Daha güncel bir rom yüklemeye çalışırken telefonumun mavi ledi yanıp açılmamaya başladı. Buradaki adımları tekrar tekrar denememe rağmen oneflash her seferinde %1’de kaldı. Bunu farklı bilgisayarlarda da denedim fakat her seferinde %1 de kalmaya devam etti. Şu an aygıy yöneticisinde telefon gözüküyor fakat mavi ışık dahi yanmıyor. Telefondan hiç bir şekilde çalıştığına dair bir emare alamıyorum. lütfen yardım edin. Gördüğüm kadarıyla başkaları da %1 hatası almışlar. Bunun nedeni nedir çözümü nedir lütfen yardımcı olun. Qfil ile manuel olarak yapmayı önermişsiniz ama onun da nasıl kullanılacağını bulamadım.

Would love your thoughts, please comment.x
