Install Sony Xperia U ST25i Android 4.0.4 ICS AOKP Custom ROM

Installing Sony Xperia U AOKP ROM?  Yes, now we can install the latest Android 4.0.4 Ice cream sandwich ( ICS ) based AOKP ROM. This after market firmware is an AOSP version. Like other open source ROM, this one doesn’t include Google applications and Sony’s apps. You can install all the necessary Gapps using this post zip file. Unfortunately it is hard to install Sony’s some apps with the AOKP framework. Although you can install media player and several apps.

Android Open Kang Project (AOKP) firmware has more option to customize. User can adjust all most all the things. Different colors for notification area icon, custom navigation button, different boot animation and many more cool features. It has the Nexus and CyaongenMod 9.1 user interface, because all of them are AOSP.

Like most of the custom ROM, this AOKP has its own kernel. Most of the cases it uses the CyaongenMod kernel. Therefore your Xperia bootloader unlock. After unlocking bootlaoder, the user receives some advantages as well as disadvantages. Overclocking, custom kernel installs are some of the advantages. Although it will erase all the user data and DRM keys it’s a big drawback.  This is not AOKP team official releases, it build by the Xperia kang project team.
