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.

Working:
  • bluetooth
  • wifi
  • nfc
  • camera
  • RIL
  • IR
  • sensors
  • portable wifi hotspot
  • wifi 5GHz
  • MHL
Not working:
  • ?

Known issues:
  • Last second of whatsapp messages is cutted Solved!
  • Possible issues with bluetooth headsets Solved!

OK guys. I proved this rom on my 9515l (Latin version) and its working and I find it really smooth. It's awesome and the only trouble I've found is a little battery drain

To people with sound issues during phone calls: try changing your baseband to different version, even the one from 4.4.2 ROM and preferably from your's network operator's ROM version - for example i have no sound issues on baseband taken from last PLAY (my network operator) 4.4.2 - I9515XXU1ANH5.
