My Epic keeps shutting itself off. It only happens while the screen is off and the only way to turn it back on is to remove the battery, put it back it and hold the power button.

Also, I'm getting issues with the WiFi. Sometimes the color of the bars changes on the status bar. It turns white, when it's supposed to be green. When it's white, everything but YouTube works. It tells me that there was a problem when the network. When it turns green, I get no issues.

I just recently began using Cyanogen on my Epic 4G. I'm actually using the Nighly Build 29 right now, but it also happened with cm7.2.0 RCO version.

Anyone else get the same issues? Any solutions?

You must of had a bad flash some where and some thing is messed up i reccommend flashing back to stock useing odin and then reinstalling CM from stock that should solve ur issue cuz i am on nightly 29 with no issues and have had no issues for a while specialy random restarting that is a sign of a hardware or software issue.

That sounds like a problem we used to have a few months ago with a ROM (SRF 1.1 or 1.2, IIRC).  The phone was "going into a coma," so to speak, meaning it was deep-sleeping (= good), but then not waking up or responding to button presses (= bad).

Some people's phones had that issue, some didn't.  The only way to know was... well, to have it or not!  (I did.  Weak-ass phone...)

The fix was to raise the base clock frequency to 200 MHz, rather than 100 MHz.  You may be having the same issue, though you'd be the first I've heard of with CM7.  Go to [Settings] > [CM settings] > [Performance] > [CPU settings] > [Min CPU frequency] > 200 MHz ... ...(o) and see if your phone stops going comatose.  If that's not it, I have no idea, but keep reading...

This is actually a feature of CyanogenMod.  CM is much more honest about the quality of your wireless connection, both WiFi and cellular, than many stock-based ROMs, because CM, unlike Sprint, wants you to know when you have poor service!

White = not connected (some say to Google servers, but it may just be the internet in general).

Green = connected (again, possibly to Google specifically, or maybe the internet in general).

Leave RC0 behind, it's 99% obsolete.  Instead, the Nightlies are almost always very stable, and of course the newer they are, the more bug fixes and features they have.   Occasionally a Nightly will introduce a bug, but the devs almost always squash those in the next Nightly or two.  I'd use the latest release unless you personally discover issues or you read of many others having issues with it.

If my solution to your first problem doesn't work, I recommend you

-- a. Check your DL of CM against its reported MD5 sum, and re-download if there's a mismatch.
-- b. Just download a different version, and check the MD5.

-- 1. Perform any pre-full-wipe backups you deem necessary.
-- 2. Reinstall, and be sure to wipe Cache, Dalvik, and /data partitions before flashing, then again afterward (/data is not usually necessary, but since you're having issues it is recommended.)

Good luck, I hope this helps: I just spent like 40 min writing this in Tapatalk!  (As opposed to ~10 on the desktop.  We need formatting buttons, Tapatalk devs!)

Yes. I had the same issues so I moved to CM9. It's much better even though it's an alpha.
