An official release of BlissPop ROM, considered to be a stable custom version, is now available for the international Galaxy S3 model, I9300. If you wish to experience all the customisations of BlissPop ROM with Android 5.1.1 on Galaxy S3, check out our installation guide below.

Points to remember

• Before following the installation guide, create backup of all important data of the phone using custom recovery.

• Enable USB Debugging on the phone to connect it with the computer and use Android SDK with it. [Navigate to Settings>> About phone. Tap on Build Number several times until a message appears saying 'You are now a Developer'. Now enable USB Debugging Mode by navigating to Settings>> Developer Options.]

• The Galaxy S3 should have above 80% battery charge to avoid power off during the process which could damage the device.

• The phone should be rooted with the latest recovery system installed on it. Also, it should have an unlocked bootloader.

• As the BlissPop ROM is in development stage, bugs are highly likely.

• The BlissPop ROM works with Galaxy S3 I9300. Flashing this on any incorrect variant might brick the device. Therefore, verify the model number of the device.

• After flashing the ROM if the device gets stuck on booting animation or experience boot loop then perform wipe cache partition and wipe dalvik cache for a few times before rebooting the device.

• Once the ROM is installed, users are advised to give 10 minutes to the ROM after the device boots up for the first time for better user experience.
