If you are looking for a good Android 4.2.2 on the T-Mobile Galaxy S2 SGH-T989, certainly give the latest Rootbox ROM a try.
Based off Android 4.2.2, the RootBox ROM brings you the best of AOKP, Per-DPI Xposed App Settings (run apps in Phone/Tablet mode), and also additional RootBox settings that complement the AOKP ROM Control settings.
Even though this is a “ported” version, it’s a still very solid build in my opinion and one of the best Android 4.2.2 ROMs you can run on your T-Mobile GS2.
So, if you want the latest Android 4.2.2, give it a go this weekend and let me know what you think!
