I recently bought the international version GT-I9300 simlock free running android 4.1.2 build JZ054K I930000XXELL4 . I researched how to root my device and I successfully did so using the Samsung GS3 Toolkit v7.0 selecting the 4.1.2 build JZ054k I9300 ELLA.
While many folks use the nightly builds of CyanogenMod there are a select few who prefer a more stable release, myself included. Those few will be happy to know that CyanogenMod has released M7 build of CM 11. The monthly snapshot — said to be more stable than the nightly builds — is derived from the May 22 nightly branch as opposed to the newer May 31 branch.
Those of you who have been looking to get some Jelly Bean lovin’ courtesy of the CyanogenMod team will be all smiles at this news. The CM team has officially announced the final CM10 stable builds are being released for a handful of devices at this time.
