Looking for a good AOSP custom ROM with latest Android 5.1.1 and root? Then check out Dirty Unicorns ROM, which comes with a load of customization along with the latest Android 5.1.1. Now, this isn’t for everyone, this is for those of you who want to run AOSP ROMs (What is AOSP?) on your Note 3 and run the latest and great Android OS. Of course, you can always use the backup and restore feature of CWM or TWRP recovery to try out the ROM and restore to your current ROM.
