Signal goes between full and none for no reason. topic

I recently have had an issue, and this only occurs on CyanogenMod (11 & 12). Basically, I'll be using my phone normally, but I'll notice my signal will go from full bars to no service every 30 seconds or so, it seems. That interval is to give you an idea. This issue does not occur on any other ROM that I've used (Cataclysm, PA, Rastapop, Stock, so forth). I've tried adding my APN as a fix but didn't seem to do anything. Information:

Sprint MVNO (Ting), running barebones CM, no gapps.

I'd love to get this solved, if anyone has ever figured this out. I've searched on Google and have seen no resolution, but have seen other's with the issue.

G3 Restarts for no reason after the Lollipop update. topic

Been Using G3 for the past 5 months. Faced tonnes of issues with over heating, restarting, etc.
But I thought all would be resolved with the Lollipop update.
Unfortunately, that's not the case here. I just updated to Lollipop last night and faced 3 inappropriate restarts in less than 24 hrs.

Any Suggestions or remedial measure is welcome guys. Using a stock and Unrooted device for now.

I got the rooted and the CWM recovery installed but for some reason, it didn't topic

I got the micromax a311 phone rooted and the CWM recovery installed but for some reason, it didn't appear to have installed the SU Binary.

When I boot the phone, it says "Unlocked" but it doesn't have the usual "Tampered" word. I used the Root Checker app and it says its not rooted .

Any idea how I can manually install the SU Binary?

Model Micromax a311
version 4.4.2
build number 4.4.012.p1.14110.a311

please help me
