What problems you have?? I dont understand, i'm use nightly from 18.07.2014 which i'm ported from i9190 and it work fine..
Please provide clear description of the problems..
my main problem
after 11july build...my network keep on disconnecting if i want to use mobile data with dual sim.
if i dont use mobile data...network works fine.
on wifi...mobile network is fine.
although single sim with mobile data works fine.
i am searching for the cause.
anyway
i am uploading daily builds from today onwards on androidfilehost.
i will update the link soon.
by the way...
the new stock 4.4.2 from SER region has some striking differences than 4.2.2
first it has no telephony-msim.jar in framework folder. (generally dual sim qcom phones are based on CAF sources so it has msim.jar everytime )
second it has new ril named libsec-ril-dsds. (seen this in galaxy grand2 duos with 4.2.2)
may be samsung has modified the CAF source heavily and made its own dual sim ril.
i dont know if this ril will work with cm sources or not.
but i will try to use and report back soon.
