The S3 have sd-card and removable battery (possible to better battery in future), thats enough to buy it instead of One X
This ROM is based on MoDaCo Custom ROM FR17 EXT4 with some changes I made, removed the most LG crap and added some Google apps.
Apps in system/app dir:
Stock Google Apps:
Calc,Phone/Contacts (Gingerbread), Desk Clock, Email, Gallery, Ginge...
You know you're rooted when you got your brand new S3 but did not even bother enjoy Stock ROM for 10 min and flashed Custom ROM right away :D
battery mod here for those who want it:
after you flash it, fix permissions just to be safe.
It's not a hardware limitation and more like a software optimization, could probably be solved by porting stuff back from the S6 ROM to the Note 5 ROM.
then why don't you do it then?
