I am using 4.42 on my rooted i9300.
my mobile goes to boot loop too many times.
like i got a call ... once i am done and cancelled the call, my mobile restarted and went into bootloop.
Had to take out the battery and put it back to get it working.
this happens at different times with different cases.
one more thing i am facing is -- FCs sometimes with play-store, sometimes with facebook and sometimes while playing games like fifa 14 or real cricket.
downgraded my i9300 back to 4.41 with gapps-modular-mini-4.4.4-20140708. lets see if i face the same issues now.
Also currently downloading 4.43
