Update Xperia Neo MT15i / MT15a to Android 4.1.1 Jelly Bean CM10 Custom Firmware

• Last modified: Android Tips

Sony doesn’t seem to have any plans to roll out the latest ICS software update or Jelly Bean to Xperia Neo MT15i / MT15a, but it can now be updated to Android 4.1.1 Jelly Bean custom ROM. You can easily install Android 4.1.1 Jelly Bean CM10 on Xperia Neo MT15i / MT15a with the tutorial given below. You need to have ClockworkMod recovery installed from before.

In this tutorial, we will tell you how to update Xperia Neo MT15i / MT15a to CM10 Android 4.1.1 Jelly Bean firmware with complete steps and instructions. Make sure you backup all your data as given in the tips below, because you will have to wipe all your data from ClockworkMod recovery later in the instruction steps. Let’s get on with the tutorial now.

What’s Not Working:

  • Lots of features. This ROM is still WIP (work in progress).

Make sure you have installed all your USB drivers for the Sony Ericsson Xperia Neo to connect it with the computer. Download Sony Ericsson Xperia Neo USB drivers! Apart from just the USB drivers, there are a few more things that you need to take care of.

1. You need to enable USB debugging mode. This helps to connect your Android phone with the PC. See here: How to Enable USB Debugging.

2. Your phone battery should be 80-85% charged. If your phone goes off suddenly because of battery, during flashing ROMs or installing mods and updates — your phone might go dead permanently. See here: How to Check Battery Percentage.

3. Backup all your important data that you might need as soon as your flash a new ROM, or make a backup for just in case, you never know when anything might go wrong. See below on how to backup data:

4. Your phone should be factory unlocked. Additional instructions for locked Android devices will be added in the tutorial for unlocking devices.

UPDATE: Android 4.1.2 is now available for this Android phone. You can download and read the full tutorial here!
