Install /e/OS minimal on a Wingtech Redmi 2 - “wt88047” (beta)

The instructions in this guide will assist you to install /e/OS on your wt88047. Please read through the instructions at least once before actually following them, so as to avoid any problems later.

It is important that you know that downgrading Smartphones on OS versions greater than the /e/OS OS version you plan to install, can cause instability or at worst brick some devices. We recommend that you check your current OS version, before attempting the installation.

It is advisable to flash your device only if you know what you are doing and are ok taking the associated risk. All /e/OS builds are provided as best effort, without any guarantee. The /e/OS project and its project members deny any and all responsibility about the consequences of using /e/OS software and or /e/OS services.

Requirements

• If required take a backup of all important data from your phone on an external storage device before proceeding.
• Do not take a backup on the same device as some of these actions will format the device and delete the backup.
• A guide on backing up with TWRP is available here
• Ensure your phone is charged more than 50%
• Check that adb and fastboot are enabled on your PC. If not you can find the setup instructions here
• Download all the files and images mentioned in the download section below before starting the installation

• Make sure you have a working data cable to connect your device to the PC. There are cables which are only for charging and do not transfer data.

• Enable USB debugging on your device. You can find the instructions here
• Make sure that your model is listed in the Smartphone Selector. Check the model supported. Where available, information on the model supported should show as a pop-up when you hover the cursor on the Device name. The model number supported should be the exact same.
