Smartphone owners LeEco Le 2 (X620 model) are often faced with a situation where official support for the device from the manufacturer is terminated, leaving the gadget on an outdated version of the operating system. The Chinese company LeEco initially used its own shell EUIbased on Android, which was not always optimized for the global market and contained a lot of pre-installed Chinese software. Updating to newer versions of Android becomes a necessity not only for the sake of new functions, but also to ensure data security and compatibility with modern applications.
The process of upgrading the software on this device can take two fundamentally different paths: installing official updates through the built-in menu or manually flashing it to custom assemblies. The first method is safe, but limited to versions released by the manufacturer, while the second provides access to pure Android 7, 8 and even 9, but requires certain technical training from the user. In this article we will analyze both methods in detail so that you can choose the best option for your use case.
It is worth noting right away that LeEco Le 2 it is based on the MediaTek Helio X20 processor, which imposes certain features on the procedure for unlocking the bootloader and installing recovery. Before proceeding with any actions, it is critically important to assess the current state of the battery and the availability of a backup copy of the data, since any manipulations with the system partition carry the risk of losing information.
Preparing the device and checking the current version
The first step before any intervention in the operation of the system is a thorough diagnosis of the current state of the smartphone. You need to go to the Settings → About phone section and write down the current build number and kernel version. This information will be needed to select a compatible firmware file, since the wrong version can lead to a cyclic reboot or complete failure of the device to turn on.
Be sure to free up space in the internal memory. To download and unpack update packages, the system requires a minimum of 2-3 GB of free space. If memory is full, transfer photos and documents to your computer or cloud storage. Also make sure that the battery charge level is at least 60% so that the data recording process is not interrupted due to a sudden power outage.
⚠️ Attention: Before starting the procedures, be sure to enable USB debugging in the “For Developers” menu. Without this item, the computer will not be able to correctly recognize the device in ADB mode, which will make it impossible to install drivers and transfer firmware files.
Download and install universal ADB and Fastboot drivers on your computer, as well as specific MediaTek (MTK VCOM) drivers if you plan to use deep firmware mode. The lack of correct drivers is the most common reason why the computer “does not see” the phone when connected with a cable, which blocks the entire update process at the very start.
☑️ Ready for firmware
Updating via the official EUI menu
The simplest and least risky way to upgrade is to use the built-in shell update mechanism EUI. This method is suitable for those users who want to remain in the LeEco ecosystem and do not want to obtain root access or change system partitions. However, you should understand that the company’s servers may be unstable, and the latest available versions may be quite old.
To start the scan, go to Settings → About phone → System update. Click the "Check for updates" button. If the server detects a new assembly, the system will offer to download it and install it after a reboot. In some cases, the update may not arrive over the air (OTA), then you will need to download the firmware file manually from the official forum or archive and place it in the root of the internal memory.
If you downloaded the update file manually (usually an archive with a .zip extension), select the "Select" option in the update menu file" or "Local update". Specify the path to the downloaded archive. The system will check the integrity of the digital signature: if the file is damaged or not intended for your regional version, the installation will be blocked with an error message.
If the automatic update does not find the new version, try changing the region in the phone settings to “China” or “Global”, then repeat the check - sometimes servers update asynchronously for different zones.
After confirming the installation, the phone will reboot into recovery mode and will begin the process of applying updates. The screen may turn off and on several times - this is normal behavior. Do not touch the device until the desktop appears. The whole process takes from 5 to 15 minutes, depending on the volume of changes and the speed of flash memory.
The transition to global and custom firmware
Many users LeEco Le 2 are trying to get rid of the heavy EUI shell in favor of pure Android (AOSP) or light builds based on LineageOS. This radically changes the behavior of the device: Chinese software disappears, autonomy and performance increase, current versions of Android appear that the manufacturer no longer produces.
To install custom firmware, you must first unlock the bootloader. In the case of MediaTek processors, this is often done through special utilities or asking for an unlock code, although for LeEco there were often exploits that allowed you to do this without waiting. After unlocking, you need to install a custom recovery, most often used TWRP (Team Win Recovery Project).
Stability| Firmware type | Android version | Installation complexity | |
|---|---|---|---|
| Official EUI | 6.0 / 7.0 | High | Low |
| Global ROM (Port) | 6.0 / 7.0 | Average | Average |
| LineageOS | 7.1 / 8.1 / 9.0 | High | High |
| Resurrection Remix | 8.1 | Medium | High |
The installation process is as follows: copy the zip archive with the firmware and Google Apps package (GApps) to a memory card or internal storage. Boot into TWRP mode (by holding down the volume up and power buttons). Perform a complete data reset (Wipe) by selecting the Dalvik, Cache, System and Data partitions, but do not touch the Internal Storage if the firmware is there. Then, through the Install menu, select the firmware and GApps archives in turn and confirm the installation by swiping.
Why are GApps needed?
In pure firmware (AOSP, LineageOS) there are no Google Play services for licensing reasons. Without installing the GApps package immediately after the firmware, you will not be able to log into your Google account, download applications from the Play Market, or use synchronization of contacts and calendar.
After installation, be sure to format the data (Format Data) by entering the word “yes” to remove encryption that may have remained from the previous system. This is a critical step, without which the phone may boot but will constantly ask for a password or get stuck at the logo. The first startup after custom firmware lasts longer than usual - up to 10 minutes.
Installing TWRP Recovery and working with Fastboot
The key element of successful flashing is the correct installation of the recovery image TWRP. To LeEco Le 2 you need to download exactly the version of the image (.img) that is adapted for a specific model (X620). Using an image from Le 1s or Le Max will result in the touchscreen not working in recovery or an error in mounting partitions.
Connect the phone to the PC in Fastboot mode. To do this, turn off your smartphone, then hold down the volume down button and connect the USB cable. The Fastboot logo or text should appear on the screen. Open a command line on your computer in the ADB tools folder and enter the command to test the connection:
fastboot devicesIf you see the device serial number in response, the connection is established. Next, enter a command to temporarily load the recovery (without writing to memory, which is safer for the first test) or permanent recording:
fastboot flash recovery twrp_image_name.imgImmediately after executing the write command, you need to put the phone into Recovery mode, using the volume buttons to navigate through the bootloader menu. If you just reboot your phone the normal way, the stock recovery may overwrite the installed TWRP and all your efforts will be in vain. This is a feature of bootloader protection on some versions of the software.
⚠️ Attention: Never use the command
fastboot oem unlockat random without checking the specifications for your specific version (region) of firmware. On some global versions of LeEco this command works normally, but on Chinese ones it may require a special code or may not be available at all without deep intervention.
In the TWRP environment, the interface is controlled by a sensor. If the touchscreen does not work, try flashing the image of a different version of TWRP or use the volume buttons to move the cursor (this is supported in some builds). Make a complete backup of your current state (Nandroid Backup) before any further actions - this is your insurance in case of failure.
Solving common problems and errors
The update process does not always go smoothly, especially on devices with expired support. One of the common problems is “bootlap” (cyclic reboot), when the phone constantly shows the logo and reboots. This usually means a conflict between the files of the old system and the new firmware or an error when installing GApps.
To solve the problem, boot into TWRP and clear the System, Cache and Dalvik partitions again, then reflash only the firmware file without add-ons. If this doesn't help, the boot partition may be damaged. In this case, you need to find and flash a separate file boot.imgcorresponding to your firmware version using the command:
fastboot flash boot boot.imgAnother common problem is VoLTE or camera not working after installing custom firmware. This is because MediaTek drivers are proprietary and depend on the kernel version. In such cases, it is recommended to look for specialized builds where these problems have been fixed by the community, or return to stock firmware if the call functions are critical.
Returning to stock firmware (Stock ROM) is the only guaranteed way to restore the functionality of all hardware functions (camera, sensors, modem) if the custom firmware is unstable.
If the phone is no longer detected by the computer at all (black screen, reaction only to charging), perhaps you have “bricked” the device. For LeEco Le 2 there is a recovery method through BROM (Boot Read Only Memory) mode using utilities like SP Flash Tool. This mode allows you to write the firmware image directly into memory, bypassing the bootloader, but requires removing the back cover and closing the contacts on the board (Test Point) to enter this mode.
Optimizing the system after the update
After successfully installing a new version of Android, it is important to properly configure the system for maximum performance. Go to the developer settings and disable or reduce the scale of window animation, transition and animator duration to 0.5x. This will visually speed up the operation of the interface on old hardware LeEco Le 2.
Check the power consumption. New cores may control the frequencies of the Helio X20 processor differently. Install battery monitoring apps and see if there are any processes that are “waking” your phone from sleep mode. If necessary, use apps to freeze unnecessary software, but do this carefully so as not to disrupt the operation of system services.
- 🔋 Battery calibration: After flashing, the charge percentage readings may be incorrect. Discharge the phone before turning it off, charge it to 100% when turned off, then turn it on and use it normally until the next full discharge.
- 🛡️ Security: If you have received root access, install an access manager (Magisk or SuperSU) and configure the rules for issuing rights. Do not give superuser access to dubious applications.
- 🧹 Cleaning: Remove the remnants of old applications that may have migrated from the stock firmware. Use a file manager to search for folders with the names of previous shells.
Regularly check for updates to the installed custom firmware. Developers often release security patches and bug fixes. Subscribing to thematic threads of the 4PDA or XDA Developers forum will allow you to keep abreast of the latest changes for your model.
Frequently asked questions (FAQ)
Is it possible to update LeEco Le 2 to Android 10 or 11?
Officially - no, support stopped with Android 7. Unofficially, there are ports of Android 9 (Pie) that work relatively stably. Versions of Android 10 and 11 exist in the form of experimental builds (GSI), but on the Helio X20 processor they can work slowly, with camera and call errors, so they are not recommended for everyday use.
What to do if the IMEI and network disappeared after the update?
This is a serious problem that means damage to the NVRAM partition. You can restore it only if you have a dump (backup copy) of this partition made before flashing. If there is no backup, you will need to contact a service center to record new data through the box, since restoring IMEI programmatically without the original data is extremely difficult and sometimes impossible.
Is it safe to unlock the bootloader on LeEco?
The unlocking procedure itself is safe for hardware, but it automatically erases all data from the phone (reset to factory settings). The main danger lies in the user's incorrect actions after unlocking: flashing an incompatible recovery or firmware can lead to the need for complex recovery via the SP Flash Tool.
Where can I download reliable firmware for LeEco Le 2?
The most reliable source is specialized forums such as w3bsit3-dns.com (LeEco Le 2 thread) or XDA Developers. There, files are checked by moderators and other users. Avoid random sites with firmware, as they may contain viruses or modified images with malicious code.
Will the warranty remain valid after the update?
Since the LeEco Le 2 smartphone has long been discontinued from production and official sale, the warranty issue is in most cases irrelevant. However, if by some miracle you have retained the warranty, then any flashing, especially with unlocking the bootloader, will officially void the manufacturer's warranty.
