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.
Boot your device with the stock OS at least once and check every functionality.

Warning: Make sure that you can send and receive SMS and place and receive calls (also via WiFi and LTE, if available), otherwise it will not work on /e/OS as well. Additionally, some devices require that VoLTE/VoWiFi be utilized once on stock to provision IMS.

Updating firmware

If you are installing from LP (5.x) stock MIUI, nothing needs to be done.
If you are installing from KK (4.4) stock MIUI, you will have to update the device’s firmware.

To find your model number, “Open “Settings”, navigate to “Phone Info”, and take note of the model number below the “model” header:
- Devices with model numbers 2014811, 2014812, 2014817 2014818, 2014819, and 2014821 should download the firmware labeled wt88047.
- Devices with model numbers 2014813, and 2014112 should download the firmware labeled wt86047.
Sideload the firmware file downloaded from the link in the Downloads section

Tip: Sideload requires actions in two places to be done. One on your phone in the TWRP UI and secondly on the connected PC which should have adb enabled. Also note the sideload process while running may stop abruptly around 50%. The console would show a message Total xfer: 1.00x. This would mean that the transfer has successfully completed.
- On the device in TWRP,
  
  select Advanced, ADB Sideload, then swipe to begin sideload.
- On the host machine, in the console , start the sideload of the package by typing
```
 adb sideload filename.zip
```
Tip: Change the filename to the name of the file you downloaded

Installing a custom recovery

Connect your device to your PC via USB.
On the computer, open a command prompt (on Windows) or terminal (on Linux or macOS) window, and type

 adb reboot bootloader
```
Once the device is in fastboot mode, verify your PC finds it by typing

 fastboot devices
```
Flash recovery onto your device

 fastboot flash recovery recoveryfilename.img
```
Replace the recoveryfilename with the name of the recovery image you downloaded in the previous section
Now reboot into recovery to verify the installation
- With the device powered off
