AOKP for Xperia Arc and Arc S — Installation Guide

The fad lately among custom ROMs has been of experiencing the stock AOSP Android experience as found on Google’s Nexus phones, and AOKP is probably the most widely developed AOSP ROMs these days. AOKP provides you with good performance, and a gazillion customization options via the inbuilt ROM Control mod. And now, AOKP is finally available on the Xperia Arc and the Arc S, thanks to an unofficial port.

However, the ROM is in the alpha stage, which means that is in its early stages and may not be completely bug free/have some issues in it. Reporting any bugs and issues you encounter in the official development page (linked below in step 3 of the installation guide) will help in improving the ROM faster.

Read on to find out how you can install AOKP ROM on your Xperia Arc/Arc S.


This ROM and the guide below are compatible only and only with the Sony Xperia Arc and Arc S, model number LT15i/LT18i. It’s not compatible with any other device and may render an incompatible device unusable. Check your device model in Settings » About phone.


The methods and procedures discussed here are considered risky and you should not attempt anything if you don’t know completely what it is. If any damage occurs to your device, we won’t be held liable.

How to Install AOKP ROM on Xperia Arc/Arc S

  1. This procedure will wipe all your apps, data and settings (but it will NOT touch your SD cards, so don’t worry about those). Backup your Apps and important data — bookmarks, contacts, SMS, APNs (internet settings), etc. This Android backup guide would help you.
    Important! Don’t forget to at least make a backup of your APN settings, which you can restore later if your data connection does not work after installing the ROM. Use the backup guide to find out how.
  2. Important! Your Xperia Arc/Arc S must have an unlocked bootloader. You can unlock your bootloader officially → here.
  3. Install ADB on your computer using the guide → here. This is required to flash the requisite kernel on your phone. (Skip if you already have ADB installed on your PC).
  4. Download the latest version of the ROM from the official development page.
  5. Download the Google Apps package, which will install the required Google apps like Market, Gmail, etc, which aren’t included in the ROM itself.
