The LeTV LeEco Le 1 Pro is an excellent phone that comes at a very low price. Some retailers are selling the phone for approx. £150. However, the phone does come with a few problems.
The phone comes bundled with an old YouTube app which refuses to update to the latest version. The phone has malware where apps are installed in the background and ads are served in the Chrome browser.
At the time of writing there was no official ROM available. Now a official ROM has been released. It can be found in this post. Installing the official ROM is the easiest way to fix the malware and app problems with the phone.
The TrustGo App from the Google Play store pointed out that the Ant Keyboard bundled app contained the malware. The YouTube problem can be fixed by uninstalling the bundled YouTube and installing the latest YouTube from the Google Play Store.
The phone had to be rooted to remove the YouTube and the malware app Ant Keyboard.
The following instructions will root the LeTV Le 1 Pro USA version only. However, rooting can brick your phone, so if you do go ahead it will be your responsiblity. Rooting also invalidates the warranty of the phone. You will also be able to unroot your phone at a later date and reinstate your warranty.
The following assumes that you are using Windows 10.
Rooting the LeTV Le 1 Pro USA Version
Install TWRP
TWRP will allow to root the phone. First it needs to be installed.
In order to install TWRP, you need to connect the phone to the PC
Lets prepare the PC before we connect it
Install Java JDK 8 using Chocolatey
Open an administrator command prompt
Type cmd in the search, right click Command Prompt and choose Run as administrator.
Copy and paste the following code into the administrative command prompt window to install chocolately
@powershell -NoProfile -ExecutionPolicy Bypass -Command "iex ((new-object net.webclient).DownloadString('https://chocolatey.org/install.ps1'))" && SET PATH=%PATH%;%ALLUSERSPROFILE%\chocolatey\bin
Install and configure JDK 8 by pasting the following code into the administrative command prompt window.choco install jdk8
Download, install and configure android studio using the defaults in the setup
Download Android Studio
Launch setup and accept the defaults
In the final screen select lanuch Android Studio and then finish
Choose the configure dropdown and then choose SDK manager
In the SDK manager, check the Google USB Driver from the SDK Tools tab and choose OK
android sdk manager google usb driver
Close the administrative command prompt and then open a new administrative command prompt and type adb. You should see the adb command returning help. This means that adb driver is installed and ready to go.
Download the latest version of TWRP onto the PC using this link
Rename the downloaded file to recovery.img
Now it is time to prepare the phone before we connect it to our already prepared PC. If your phone does not boot into android then you can skip the whole of this #4 section and move on to #5 (TWRP) section below.
Go to settings and then about on your phone. Unlock developer options by touching the build number several times.
Android : Settings -> About
Go to settings, developer options and enable USB debugging
Android USB Options
Connect the phone to the PC
In an administrative prompt check the phone is connected correctly by typing
adb devices
You should see a device under adb devices
Download SuperSU and use the file manager to put in the root directory of the phone
Lets flash TWRP into the phone. You should not lose any data, but if you have data on the phone you should make a backup just in case.
We need to boot into fastboot. On the PC, open an administrative command prompt and type
adb reboot bootloader
If your device does not boot into android, you can go into fastboot by switching off your phone, hold the down volume key and then press the power button.
Once in fastboot you should see a small picture of a penguin in the middle of the screen. To check that the phone is connected, in the administrative command prompt type
fastboot devices
You should see your device listed
In the administrative command prompt make sure you are in the directory of the recovery.img file and type the following
fastboot flash recovery recovery.img
Once the recovery is flashed type the following and hold the up volume key to restart in recovery
fastboot reboot
You should now be in TWRP. In TWRP there may be an option advanced or settings to install SuperSU. If the option is not there use install to install SuperSU (downloaded earlier) from the root of the phone storage.
Once installed you can reboot into android and following the instructions in the SuperSU app.
Once the installation is complete download the RootChecker app from the Google Play store and check if the device has been rooted.
Fixing the problems with YouTube and removing the malware
Install Easy Uninstaller, Stubborn Trojan Killer and Malwarebytes Anti-Virus from the Google Play Store.
Uninstall YouTube and Ant Keyboard. I uninstalled Cantonese Keyboard Language and Mii Browser as well as I was not using these. If you start getting errors, simply reboot your device.
Download and install the YouTube app from the Google Play Store.
Run the Stubborn Trojan Killer and remove any found trojans.
Run the Malwarebytes Anti-Virus and remove any found viruses. Run the privacy scanner and follow the recommendations.
Once you have successfully completed the above steps then your device should be malware free and completely usable.
