There are a lot of custom ROMs available for Xiaomi Redmi 4A but you to install them, you need to unlock the bootloader first. This post has all the instructions and files needed for you to unlock the bootloader on Xiaomi Redmi 4A. We will be using the official Mi Flash Unlock tool for this tutorial.

Backup and Other Important Tips

Always backup your important data that you might need after you install a new custom ROM, an official software update or anything else. Make a backup for just in case, you never know when anything might go wrong. Read: How to Backup Android Apps, Text Messages, WhatsApp, Call History.

Samsung users can also back up data using Samsung Smart Switch to your computer. Smart Switch helps to move data across different Android devices i.e moving Samsung Galaxy S7 Edge backup data to Samsung Galaxy S8.

If you already have a custom recovery (ClockworkMod, TWRP etc.) installed on your phone, we strongly recommend a backup using that as it creates a complete image of your existing phone set up. [Tutorial: How to Backup Android Phone using TWRP]

A few more optional tips that you should remember:

1. Having problems connecting your Android phone to the computer? You need to enable USB debugging mode. See here: How to Enable USB Debugging — for Gingerbread, Ice Cream Sandwich, Jelly Bean, KitKat, Lollipop, Marshmallow and Nougat.

2. Make sure your Android device is charged up to 80-85% battery level. This might help you: How to Check Battery Percentage. Why? Because, if your phone goes off suddenly while installing a custom ROM, flashing an official firmware update or installing mods etc. — your phone might get bricked or go dead permanently. No one wants that, right?

3. Most of the tutorials and how-to guides on Team Android are for factory unlocked Android phones and phones. We recommend not to try our guides if your phone is locked to a carrier, unless we have specified the carrier name or device model.

4. [IMPORTANT] Copy all the backup files from your SD card to your computer as internal memory will be wiped clean while unlocking the bootloader.

If you are a developer and would want to unlock the bootloader, we recommend doing that before you set up the Google Play Store, install apps or anything on your new phone because the security feature in Android clears out everything from your phone when unlocking bootloader of the phone.
