Hey guy's I have a Samsung Galaxy S4 I337M version running Android 4.3 standard Telcel load. The phone is rooted but everytime I flash any rom on it, it looses sound and sometimes wireless. Gummy is what I wan't to use. Is there anyway I can backup the kernel here on my stock load and restore it on gummy 4.4 when I flash it ? Can the kernel of 4.3 work on 4.4 ?? If so how do I do it ?? Thanks....
