[ROM][CM12.1][UNOFFICIAL][2016-03-20] CM12.1 for Galaxy S4 VE (GT-I9515)

[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.​

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

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 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.

I have the 9515l and when I call, I hear the sound noises with cm 12.1. But the fix you showed is only for 9515, is there anyway I can fix my 9515l?

You should try different basebands for i9515L. You can extract them from firmware downloaded from sammobile.

What if I just flash the baseband you posted on your first post? There is no way it works?

I have the I9515LUBU1BOC4 which is the one that came after flashing cm 12.1. I tried the 9515 baseband but, as I told you before, I couldn't and I don't know how to try flashing other baseband, so I haven't try anything else.

Thank you sombree but I still have noises during call. Sometimes only on loudspeaker. Sometimes even on handset. Is there a way we can find out what's the problem causing this issue?
