Galaxy S2 i9100G Gets Jelly Bean Update with Codename Android ROM [How to Install]
Among the two variants of Galaxy S2 (i9100 and i9100G), the G-variant seems to be drawing more developer attention with a constant rush of custom Jelly Bean ROMs.

Among the two variants of Galaxy S2 (i9100 and i9100G), the G-variant seems to be drawing more developer attention with a constant rush of custom Jelly Bean ROMs in recent times. Yet another Jelly Bean custom ROM, Codename Android, has been released for the i9100G model.

Thanks to XDA senior member Samyam2002000, the Codename Android ROM ports Android 4.1.1 Jelly Bean update with advanced features like butter smooth interface, enhanced notifications, Google's advanced voice recognition assisted search, improved browser and more to Galaxy S2 i9100G. It also harbours a few built-in performance tweaks as well as customised settings for changing different aspects of the interface.

Despite the rich feature set, the Jelly Bean update may include a few untested bugs or broken features, as it is not an official Samsung release. Besides, certain native features on Samsung's stock ROMs may be unavailable or partly functional.

Here is the complete list of known bugs and broken features found with this update, as stated by the software developer:

  •  FM radio is not supported
  •  Surfaceflinger: short screen flash after CRT-off animation
  •  External storage cannot be mounted or accessed on PC (however, the same is accessible through file manager on phone)

Prerequisites

  • The ROM and the installation instructions are applicable for the Galaxy S2 i9100G model only and will not work with i9100 or any other device. Verify your device's model number through Settings > About phone.
  • If your Galaxy Ace is already running on a stock Jelly Bean ROM or CyanogenMod based Jelly Bean ROM, then you could skip installing stock Android 4.0.3 XXLPQ firmware and ClockworkMod recovery on your phone. Otherwise, please do install the software packages before continuing with the Codename Android ROM installation steps.
  • IBTimes UK advises users to backup apps, important personal data and settings (bookmarks, contacts, SMS, APNs and other internet settings) to avoid data loss while installing the Jelly Bean update.
  • The instructions provided in this guide are meant for reference purpose only and do not cover any warranty claims involving device damage or issues arising out of using this firmware update. Users are advised to proceed at their own risk.
