UPDATE : LeEco Le 2 x620 / x620 Pro / x625 Pro baseband – imei repair

Here we are again, for another unbrick/rescue mission.

This time we will unbrick our LeEco Le 2 x620 / x620 Pro / x625 Pro series from so-called “Red light” brick. If you flash a wrong ROM using TWRP, your phone will have no sign of life, only a blinking red light when you plug USB cable and some Mediatek ports under your device manager (if you have drivers installed).

It was much easier for old MediaTek series like x600 or x500 from LeEco to flash an SP Flash tool ROM, but after Helio X20, things changed — there is secure boot protection and we can’t just flash like a regular MediaTek SP tool ROM. We need different “download agents” and a certain authentication file to bypass this protection. This guide works for both unlocked and YES for locked bootloaders. And there is a Youtube video that you can watch if reading can be confused sometimes, this is a tricky guide, but the only complete guide that will answer all your questions.

And there is a Youtube video that you can watch if reading can be confusing sometimes, as this is a tricky guide, but the only complete guide that will answer all your questions. There are less pictures in this guide, but the video shows every step, guide is written in the same timeline as the Youtube video.

Downloads: Flash tool , Rescue Rom

Let’s start.

Double click “flash_tool.exe” inside the x620_flash_tool folder. Choose “MT6797_Android_scatter.txt” in the ROM folder LeEco_x620_SP_Rom if you see an error, if you don’t, do it as the first step by clicking “Scatter-loading” tab right of the window. Next, click “Download Agent” above and choose “DA_PL_HIGH.bin” from “secureboot” folder in the flash tool program folder. Press CTRL + Alt + S to open “Authentication File” section in flash tool and browse to secureboot folder again and select “auth_sv5_letv.auth” file. Untick “recovery” and “boot” images from the list and make sure you have “Download only” selected. If you try to flash recovery and boot partitions too you will see an error like this:

Make sure your phone is completely off. Press “Download” (green arrow looking down), then just plug the USB cable without pressing any other button on the phone.

A new device will be found under device manager, use this driver to setup manually MediaTek Preloader VCOM USB port by selecting the inf file inside the driver folder.

Flashing will start like in the picture, if not, ignore any error, unplug the USB cable, press download again (green arrow looking down) and plug back USB cable in.

Wait until flashing is done, you will see a green “OK” sign showing its done.

Now, unplug the phone from PC. Next, we will flash recovery and boot partitions individually. We need to change download agent from DA_PL_HIGH.bin to DA_BR.bin as the first step here. Again, they are in the “secureboot” folder inside the SP flash tool program folder. Press “CTRL + Alt + V” to open “Write Memory” tab under “Window” menu above.

After you select “Write Memory” a new tab will come up looking like this:

We will flash boot image first, (the pictures are for recovery image flashing, don’t get confused, both will be flashed same way, only files and hex values be different) from “File Path” browse to the ROM folder and select “boot-verified.img” file.

Change the value in the “Begin Adress (HEX)” to “0xf900000” (copy paste from here), leave “Region” as “EMMC_USER”. Click “Write Memory” above (phone is unplugged and off).

Now this step is important: Press Volume + button on your Le 2 and plug in the USB cable, keep pressing Volume + button until flashing is done.

Keeping Volume + button constantly will open our desired MediaTek Preloader VCOM USB port, if you don’t, MediaTek USB port will open and flashing will give an error, if you keep pressing Volume + this will trigger Preloader port to open.

Look at the pictures to see port name.

From “File Path” browse to the ROM folder and select “recovery_stock_works _after_brick.img” file. Change the value in the “Begin Adress (HEX)” to “0x8000” this time (copy paste from here), leave “Region” as “EMMC_USER“. Rest will be the same as is described above.

Press Volume + button on your Le 2 and plug in the USB cable while phone is off, keep pressing Volume + button until flashing is done.

That’s it, now it’s time to power on our bricked Le 2 phone. Next guide will be Baseband and imei fix if you had lost them during brick.

LeEco Max 2, might be the best buy for the money you spend as for 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 being 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.

STEP 1:

This rescue operation is not only for hard bricked Max 2’s, you can use this method to return of 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, it’s 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.

STEP 2:

Unzip FlashOne 1.9 file that you have downloaded anywhere you want and double click the “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, the 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

After decompressing is done, the actual flash procedure will start.

If you get an error like this, just put your phone into EDL mode again by pressing both volume buttons and power buttons (hear the USB unplug and plugged sound), then click the 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 power itself and reboot, 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.

STEP 3:

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”. The 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, it’s multilanguage and Google preinstalled.

See you in the next guide.
