Phone stuck on boot screen

My Epic Touch is stuck on a constant boot loop, just showing the sprint screen over and over. I'm unsure what to do to fix this. I read to restore a factory rom, but unsure if such a thing exists or not...
Can anyone help me?
? Not enough info..............................................?

[Q] SGS3 Won't Boot [But Vibrates]

It's weird...whenever I try to do any of those things, the screen will turn on for a moment [the backlight, no logo or anything comes up] and then after about a second immediately turns off....I tried injecting a rooted version of the stock rom with Odin into my phone, but I kept getting strange error messages like TouchWiz isn't working and some other android process isn't working.
[That didn't work, so I decided to try a different method. This is where I ****ed up, because I forgot to go back to stock rom...]
Anyways, after that, I tried to use the SGS3 Toolkit [if you search sgs3 toolkit xda, it'll come up] and I tried to use that to root. I went to "rooting options" and i selected option number 3, the all in one. I got to the point where it mentions your phone must be in USB debugging, and now nothing comes up when I try to start the phone..but it vibrates whenever I hold the power button long enough [as if it was working normally]. I can't get into download mode right now, either...
How do I reverse this and go back to stock? Please help...thank you so much.
EDIT: It's weird...whenever I try to do any of those things, the screen will turn on for a moment [the backlight, no logo or anything comes up] and then after about a second immediately turns off....
I'm basing this answer based on how I understood what you said...
But, if you're already rooted, then hopefully you've made a backup before installing another ROM. If you have a backup, then put into recovery and backup.
I wasn't already rooted, I was trying to root it. I can't get into recovery.

Can you get into download mode? By holding Volume up, home up and power.

Was your phone plugged in when you tried get get into download mode? if so, try unplugging it and give it another shot. the s3 can be kind of funkysometimes.

Same thing, no dice :[
Plug it into the computer and see if anything shows in device manager.
I hate to say though, I think you may be bricked....
Unless anyone else can think of something to try?
Sorry man...

Also you can try safe mode. Doubt it'll work but I just learned how to do it so thought id suggest. Hold volume down + power.

Have you plugged into the computer and checked device manager yet? What does it say?
I think if it says something like qhsusb that means its bricked.
I'm hoping someone can verify that though since I'm going by memory.

No it should even if it's hard bricked. Maybe the pc isn't recognizing it

Well, I sent it back to T-Mobile and said hey it doesn't work. Let's see if they say anything about it. They sent me a new one, though
I'm having exactly the same problem with my T-Mobile Galaxy SII T989 running Open Kang AOKP JB Jelly Bean. After reading this thread, and another related thread (http://forum.xda-developers.com/showthread.php?t=1679492), my less than scientific observation is that pressing/massaging/jiggling the power button seems to bring the device back to life. At least until it flakes out again. The posts in this thread were a big help. I was going to ditch the ROM, which would have been a shame. Thanks.

Ok, I don't deal a whole lot with phones. Mostly tablets. I'm just answering your post to remove the fear that's going through your mind right now. Good news is, your phone isn't bricked. Its just stuck at a boot loop. I'm familiar with the app you're talking about. Before you rebooted the phone, it should have made a back up. Find it, by hooking it up to your laptop. Or, if you remember the name of the font that was on your phone, originally, you can get into your phone via laptop, and try to reinstall your old font.
Hope this helps a little bit.

You should be able to push a file using Android SDK. If you don't have it, you can get it here. http://developer.android.com/sdk/index.html
This will help you to push files to your phone, in your case, the font file. I guess you could always send an email to JRummy, the developer of ROM Toolkit Pro, and see what he recommends. That may be an easier route to go.

[Q] [Help?] R800at Stuck in bootloop

I had just received this phone, and I haven't modded anything. When I got this phone, it was stuck in boot loop, and I have no idea what the previous owner did to it. He said it was a battery issue, but the battery charges and holds a charge. The phone boots, makes it to the ATT screen, and reboots. I have no idea how to boot this phone into recovery, or if it even has one (which would be pretty crappy on Sony's part if it didn't.) Is there any way this can be fixed? Also, I tried downloading flashtool and it's not compatible with my version of Windows 8 (Eval copy :/ ). Am I out of luck?
BUMP
Need help ASAP.
See if you can get into recovery by either spamming Vol up or the back button when you turn the phone on.

Is your phone rooted or stock
Sent from my LG-E973 using xda app-developers app
I had a weird issue similar to this over the weekend. One minute my phone was fine then the next minute I tried to wake it and the screen wouldnt come on. I even held the power button down (to turn on or off) and nothign was happening. I was like "W....T....F......?!?!" I was pretty nervous as I LOVE this phone. I couldnt think of anything to do and I couldnt plug it into a PC or charger since I was at a bar with some mates. Long story short...after a few attemps to just keep pressing the power button down lol it finally started up from a reboot.
Very weird indeed....everything has been fine since and I am running stock.

To add, do you have the latest update?
Is your battery calibrated?
