[Galaxy S 4 i9505 Android Development] sombree:
Hi guys!

I've succefully ported CM12.1 to Galaxy S4 Value Edition (GT-I9515).

I strongly recommend to perform a backup of your current rom before installation.

To all people -

do not try to update rom manually with jfltexx nightlies

- i9515 is jfvelte!

Valid updates are only in my threads (at least for now).

Remember - after every update you should wipe your cache and dalvik cache.
