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.

Later update…the OS still not booting.
I tried to apply again twrp (multiple versions)
WHen pressing vol+ and power, it keeps connect/disconnect from USB – no twrp.
If press vol- and power, if gets the recovery prompt, and that’s it.

Any suggestions guys?

Any idea how to flash a newer version? cannot start android OS to do the update, nor the TWRP to flash it from there.
Can this be flashed via adb fastboot?

Thank you for your fast response.
I tried to copy the zip, but it say that there is no enough disk space..
It seems that I copied over and over roms into /SDCARD/, after flashings, the zips dissapeared, but from 12GB free disk space, twrp only shows 778 MB…

If I flash another rom, will the imei work?

This is a life saver.
It was stuck in a loop, showing nothing on screen.
Now after following the procedures, it boots, but it blocks at android.
I will take the steps again, maybe I’ve done something wrong, or I should wait a bit more(Already 10 minutes)

However, I got a step fw. THANK YOU !!!!

Hello again,

I never succeeded to write the IMEI. Maui worked, said uploaded, but it was still blank when checking.
So after many roms, I decided to format it again, and try your tutorial.
I went to format whole flash (inlcuding bootloader)

Now when I connect it to the PC, i only get in device manager the Mediatek USB, not the VCOM like I used to.

I cannot do anything at this moment(i am getting an error status brom cmd startcmd fail.
If it’s possible, it would be much appreciated a hint.

Thank you!

Regarding the IMEI, do you have any idea?
Even if it’s uploaded with maui, in os at 06# said blank

IMEI WORKS.
For other that have the problem:
I found an official ROM (FULL_S2_PLUS_S2_PLUS-CN-FN-HEXCNFN5902606141S-5.9.026S.zip)
Patched via stock recovery, by copying the zip as update.zip. Didn’t worked via twrp.
After using the official recovery, used maui and worked.

ty all and good luck with yours.

Thanks for the tutorial, I followed all the steps and I managed to revive my Leeco Le2 X620, but I follow the procedure to recover the baseband and the IMEI and it does not work. My phone’s camera does not work either.
Please help me with these problems.

Hi. Thx for this great post. I successfully unbricked my phone second time with this post. Just a note: My Phone was in boot loop, using DA_BR did n ot work at write memory stage. I used DA_PL_HIGH at write memory stages and it worked like a charm! Thanks.

FOr devices in boot loop, it may be hard to connect to device. It disconnects regularly. Holding power button until application detects and starts communication helped me.
