For Sprint Note 2, there is a ported version of Ditto Note 3 ROM but WiFi is broke and a lot of things are beta, please wait 1-2 weeks until the ROM is more stable. For Sprint Note 2, you can install the Verizon R3Ds ROM on and simply add Sprint 4G LTE APN.
UPDATE: Please do not try installing Verizon R3DS ROM on Sprint Note 2, it seems like the APN method only works for other Galaxy phones like S3, S4, S5, and Note 3 but not on Note 2.
All of these custom ROMs support Galaxy S5’s new “Ultra Power Saving Mode”, which can give you gobs of battery life. On full 100% battery life, you can get 14 days/2 weeks of battery life! That’s probably unheard of in other smartphones out there but it is possible with the Note 2 now, thanks to custom ROMs.
