Upgrade Motorola Atrix 4G to Ice Cream Sandwich Via Unofficial MIUI 4

February 29, 2012

We’ve already heard of the news rolling out that the Motorola Atrix 4G won’t be receiving Ice Cream Sandwich anytime soon. But, word has come out that the Atrix 4G is getting some developer love with a brand-new unofficial MIUI 4 port for the device.

This unofficial MIUI 4 port for the Motorola Atrix 4G may yet be the best alternative that you could have while waiting for the official update from Motorola. As you may already know, MIUI 4 is based on CyanogenMod 9 source.  MIUI 4 is loaded with a heavily themed UI with tons of customization and various options exclusive to the ROM that is not normally present on stock ROMs.

The only downside of MIUI 4 ROMs is that they are not completely stable for daily use yet, as CyanogenMod 9 is still under heavy development.

Some of the known issues of this unofficial MIUI 4 port for the Atrix 4G are as follows (verbatim quote from developer):

  • First boot takes little long
  • Media scanner can’t scan sd-ext
  • USB mass storage can’t mount sd-ext (But able to access in file manager)
  • MIUI Theme seems to not working correctly sometimes.
  • Data not working.

If those bugs don’t scare you, read on to find out how you can install MIUI 4 on your Motorola Atrix 4G.


  • Rooted Atrix 4G with ClockworkMod Recovery installed
  • Fully charged battery or at least 70% of battery left
  • Backup of your personal phone data


  1. Download the MIUI 4 ICS ROM here and save it to your computer.
  2. Connect your phone to your computer via USB cable.
  3. Copy the downloaded MIUI 4 ICS ROM file to the root of your phone’s SD card.
