[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] bANONYMOUS:
I was running the SGH-i747M with CWM 6.0.4.7 and testing out some 4.4.2 ROMs, I got another phone to play with now and I gave this one to my girlfriend but she doesn't like nightlies so I was trying to install a 4.2.2 or 4.3.1 stable ROM and they won't work. I read online that it might be due to the CWM being too new because it's support is for Android 4.4.x. So I downgraded CWM and that didn't work either. I ended up convincing her that nightlies aren't that bad and shes currently running Carbon but she hates flashing the new nightlies so I do it for her every few days or so. I've noticed though that this phone is acting up really weird since I tried to downgrade CWM and then install the current one again. Sometimes it reboots at random, I gave the phone to her with BAM 2.0 RC2 (I know, shame on me), and that was horrid, so I tried CyanogenMod and that was "okay" but she said it's boring and she wants more features, so I switched it to Carbon because that's what I'm running on my SGH-i317M and she seems to like that, but it's still acting really weird.

When I was using the SGH-i747M while I was waiting for the new display to come in the mail for my SGH-i317M, I was running BAM and the only thing was it was a battery hog, and ocasionally I would get a "blame tyler" error for some things but it was never repeatable, I switched to Carbon and I was running completely stable on the nightlies, I used it for my day to day and not one problem, after switching over to my SGH-i317M now running CarbonROM, still flawless, not a single problem, fast, good battery life, signal strength is always good, but the phone I was on, running the same ROM, is now glitchy as hell and she's talking about getting an iPhone 5S now.. guys you gotta help me here, I just got her to give up her iPhone 4 for this S3 I gave her, I need this phone working, it is a critical situation lol.

The camera app will take one picture, then the screen will freeze and when I close the app, it opens right back up with the same picture, when I completely close the app, it opens up saying can not conect to camera and the only solution is to reboot the phone. It randomly reboots on it's own some times, the battery doesn't last more then a few hours (between 2 to 3 hours depending on use and when I was using it on Carbon, I got 30 hours off of a single charge once, but the average was around 20 hours of use before it would die) and she was telling me while she's on high brightness but never full brightness, the phone gets really hot so there's something wrong from when I flashed an old CWM using Odin, and then flashed it back to the current one.

So how can I do some kind of full wipe everything and make everything better procedure? Does this exist yet? Is it a real thing?

I'm thinking some kind of recovery wipe, completely wipe everything except the boot loader so I can install a fresh copy of CWM using Odin, and then some kind of AOSP ROM that's stable but I think she likes Carbon now so we might just stick with the nightlies as long as these random force closes and random reboots stop, and the camera works, I mean, you can't instagram without a camera, so that makes this phone nearly useless for her. One picture, freezes, reboot the phone, opens picture from gallery, then hipsters it out, then shares it.. not exactly the seamless method she was looking for lol

Please help guys, I really don't want to see another iPhone laying around the house.. ugh..
