Is it that difficult to realize you are on custom ROM, sh it can happen, why not wipe and flash stock kdz to rule out your fears of hardware issues.

When I was still in stock rom i still had this problem but it doesnt come out so often. So id say yes, its hardware problem right?

Well flash stock kdz, wipe. No kernel or mods.
If still happens than yes hardware

It's seeming that it's the kernels that are killing our fone. It's the 1 common denominator

Find a different cm10 compatible kernel and flash it through cwm or through Odin.

What is the name of the ker el you flashed. And link possibly.

Have you tried going into recovery? Maybe there is still cwm? Since your flash back to stock seems to have been unsuccessful.

Just had a thought. It's easy to get stuck on boot when you flash back to stock without wiping.
If you can wipe it/factory reset that could solve you're problem.
And it'll boot up.
It's confusing cause it looks a lot like your phone not booting cause of the kernel

Yeah just take the battery out and get into android recovery by pressing volume up, power, and home button. Then wipe/factory reset and reboot system.
^^^^ just like the gentleman said. Reboot into recovery and factory reset it. It should boot up after that.

Recovery isn't there, any way I could do it from adb?

If you can get into download mode, reflash the stock tar in Odin again or just flash the cwm or trwp recovery tar and reflash a different kernel
Sent from my SGH-T999
Here is a link to Odin-able recoveries that you can use. I also agree with the others that this is probably a mismatched ROM/Kernel that is preventing you from booting up. The only problem I foresee is that you Odin'd a stock image, so now you are not on CM10 anymore. Now you'll have to find a TW kernel that you can flash, like Morfic's or I think Ktoonez has one too. But you can ADB push the kernel to your SDcard so that when you flash the recovery above, you should be able to then go in and find your kernel and flash that.
What I suggest first is to Odin one of the recoveries (TWRP is what I use) and then once that is done, go in and Factory Reset and try to boot it up. If it works, great. If not, then you may need to move on to pushing a kernel and flashing that.
Volume up + Home + Power takes you to Recovery.
Have you tried that?

Tell people what worked so that it can be documented when it happens again and I can link them to something they didn't search for themselves.

Yes but when you flash stock rom using odin everything is original and you wont get problems with your phone. Perhaps on your other phones you flashed costum roms that werent stable.

SWAP?

I have a tmobile black s3 which is in 100% condition with excepetion to it gets hot for some reason upon to much use. I also have a white att s3 which has a cracked screen. I need at&t so im wondering, is it possible to swap the inside of the white and put in the black? Im hoping someone knows so I can find someone to do it.
My guess would be yes you could do that. For the heat problem though, if you are using stock build UVDMD5, either try Odin flashing the LJC firmware, or.Just flash the LJC modem.

WELL WHEN IT WAS STOCK IT GOT HOT. NOW IM ON WICKED V10 http://forum.xda-developers.com/showthread.php?t=1804260 AND IT STILL GETS HOT..I DONT KNOW WHAT THAT LJC OR UVDMD5 IS.
It's the build number. Refers to the firmware. Check what baseband it says you're on. If it's the UVDMD5 one, go to the modem thread and flash a different one and see if it helps

Heres my info..doesnt match anything u mentioned
Ok, I'd suggest making a nandroid then factory reset and test. If it stops heating up.then there may be some old or corrupted data causing a process to hang. If it still happens you can restore the nandroid and try a different kernel. Otherwise see if there are any other reports of the same thing in the Rom thread.

You'll still be on your custom Rom, but it'll wipe everything so it'll be like you freshly installed it.

Flashing without wiping can help, but not usually. It's the data separate from the Rom that usually causes problems.

[Q] Android is upgrading message after every boot

Hello, I was just wondering if anyone knew a fix for the android is upgrading, optimizing apps # of # message thats been popping up after every boot? I'm on LG Optimus G Pro e980. My bootloader is unlocked so could I just flash the stock rom with CWM? and maybe that will put it back to normal because factory reset isnt doing the job completely.
ICS did it and now Jelly Bean is going to do it.
I wonder if at all you'll find a solution, because I don't think you'll find one.
Oh ok

What.... It's your kernel it sounds like. Did u flash a custom kernel?

I'm running the kernel from hkfriends and cwm recovery
