Looking to revamp your Galaxy S4 with the latest and great Android OS?  Tried TouchWiz Lollipop and disappointed?

Well, if you are in town for the latest Android 5.1.1, you can grab the latest CM12.1 ROM for your Galaxy S4.

For GT-i9505, T-Mobile SGH-M919, Verizon SCH-i545, and Canadian SGH-i337M, you will be able to enjoy the full Android 5.1.1 CM12.1 ROM.  For AT&T and Sprint S4, you can try the CM12.1 with Android 5.1 ROM as fully-compatible Android 5.1.1 version is not out yet (but still almost identical).  For GT-i9500, try Euphoria OS ROM instead!

With latest Android 5.1.1/5.1 brings a ton of performance improvements.  One of the biggest improvements I saw was with battery life, you can expect much longer battery life and I found my phone didn’t heat up as much when playing games for long time.  There are many other improvements to performance and overall OS so this is definitely worth the upgrade.

Also with latest Lollipop, you will be able to use your 32GB+ microSD cards as it now has full exFat support unlike KitKat AOSP ROMs.  So, definitely check it out this week(end) and do let me know what you think!

To install, reboot into recovery, make backup ROM, wipe data/factory reset, install ROM, install Gapps, install SuperSU, and reboot.  (If for some reason you end up in a bootloop or get force-closed keyboard error on boot, reboot into CWM recovery, go to Mounts & Storage->format /system.  For TWRP, go to Wipe->Advanced Wipe->Wipe /system.)
