This is a community forkable ROM, so feel free to use for your own projects as long as you give me credit!
Official GT-P5113 OTA with root, busybox, deodex, init.d, zipalign. ALL files from OTA are present. (Look, even those pictures and video are there!)
The point of this ROM is not to be small, but to be completely 100% stock and used for other projects, thus it has 0 debloat and is big (but no different than any other Stock Samsung OTA).
Use a custom recovery. I prefer TWRP. But there's also CWM.
Wipe Data/Cache/Dalvik Cache (Factory Reset) the installer automatically wipes System, but you can do that too if you're nervous.
Flash the zip on a 5113! People who know what they're doing say it works on a 5110 too!
If there are issues booting make sure you have the Jellybean bootloader installed. This is from the CM10 thread, I didn't make it.
