The S3 users can now rejoice as a new CyanogenMOD-based Android 5.0.2 Lollipop custom ROM has been released for Samsung’s 2013 flagship smartphone, Galaxy S3 GT-I9300. The new custom ROM is CyanogenMOD CM12 series Beta-1 version which has been developed by a XDA Developer forum member who goes by the moniker, JustArchi. The other contributors for this release include arter97 and Moster2, who are both senior members.
The Custom ROM has a size of 223.9MB and is based on the Android Open Source Project 5.0.2 Lollipop. Keep in mind that this is an unstable and experimental Beta-1 CM12 version. There are some issues that still need to be fixed. The features of this MOD which are functional on the Galaxy S3 are updater script, kernel, OpenGL for CPU rendering, MALI blobs for GPU rendering, HWComposer, Rotation, Camera, Wi-Fi, Bluetooth, Sensors, NFC and GPS. Vibration and Radio Interface Layer is also applicable.
For the first step, you need to download the CyanogenMOD into your PC. After this, you need to connect your Samsung Galaxy S3 to the PC via USB cord. After this, place the Android 5.0 Lollipop zip file into your phone’s SD card storage. Keep it in the root folder. Your device must be rooted for this and ClockworkMod Recovery Tool should be installed.
Turn the device off and connect to PC. Perform the usual Recovery mode sortie by pressing, Home, Power and Volume up button together. Clear your phone memory after entering Recovery Mode. Then, clear cache memory by selecting the ‘wipe cache partition’. Go back to ClockworkMod recovery and select ‘advanced’ and press ‘wipe dalvik cache’ option.
Install the zip from SD card after returning to main recovery screen. Once, this is done, enter the installation process. After installation, go to ‘+++++ Go Back +++++’ and re-start your device through ‘reboot system now’.
