Samsung epic won't boot past b/w samsung screen

I'm not sure if I'm posting in the correct place as this is my first time, so I apologize in advance if not. As my the title states I currently have a samsung epic 4g that will not boot past the samsung screen. The phone is not rooted and was running stock software. This phone also will not load a recovery menu as it will not boot past the samsung screen (and yes I'm aware of the redundancy). I have tried flashing older stock files using odin and I get a successful read with no errors, however when the phone resets post flash it will still not boot past the samsung screen.......PLEASE HELP I am at my wits end and open to suggestions. Thanks

Best I can say to you both is get a stronger cable if your not already using one and if you do have a cable other than the oem one then try leaving the battery out of the phone and hold the power button for about a minute to let the capacitors discharge then let it sit with the battery still out for about an hour :/ if you don't mind me asking, what happened to the phone before the issue started?

Try to Odin with the battery out.

Its possible to odin without the battery in? How does it populate the com and do you put it in download mode first then pull battery or just plug it and let it fly?

Thanks for the replies. I am trying "the duce's" advice first, no luck yet. She had went to take a picture of the "beautiful sky" last night in the hot tub and dropped it. I immediately took the battery out and when we got to our apartment took the hair dryer (on medium heat of course) to it. I then put the battery in and turned it on and it worked! Until she decided it needed a restart and it hasn't came on since...

Ok so I just tried to flash with odin with battery out I did put it in dowload mode after plugging it up....I removed the sd card as well. Now it boots to the samsung screen but the difference is that now the red led stays lit and the capacitive keys on the bottom row do as well. Any suggestions?

In that case, I would make sure every last bit of moisture is out of the casing by leaving it covered by rice over night.... it might be short circuiting :/

That's just odd :/ I honestly haven't a clue as to what may be going wrong.... at least you made some progress with the capacitive buttons lighting up and your notification led is lighting, usually that's a sign it'll boot

Get this....never got it to boot using odin or by completely discharging the capacitors but on a hunch changed out the lcd this morning and boots right up. What the heck, does anyone know why this worked? Haha very confused now even though the issue is resolved.

Must have been some kind of failure mode for hardware check then. I had the same thing with my airbag switch in my truck. Airbag light came on because the stupid bulb in the switch was blown. Almost cost me $35 for a switch instead of $1.50 at Radio Shack.

Has anyone been able to boot into safe mode(hold power button and capacitive menu button) after the phone not booting normally?

im rooted and finished flashing one of the roms, now it seems like its stuck on boot screen.... do i just leave it on? or do the whole flashing process over again?

You can try a reflash, restore your previous nand backup and try again, or Odin in a prerooted ROM and start from there. But if it goes more than a minute on SAMSUNG you are done. After flashing the S will take a few minutes (or whatever boot screen the ROM has) while it rewrites Dalvik cache.

My epic is doing the same thing. It was stuck in recovery menu when I pulled it out of my pocket. Rebooted and stuck on sanding screen.

I figured out what I did. I installed wrong kernal... noob for me lol

Bricked my phone. What do?

So I was playing around with different kernels and whatnot but it froze while I was flashing back to stock. I pulled the battery and tried to reboot the phone but only the blue LED came out. Anyone know how to solve this issue or am I screwed?
I tried getting back into download mode but only the blue LED notification light turns on.

As a last resort try a USB jig. I wouldn't mod a Samsung without one.

There are several OG Epic tricks you can try. Try removing battery and SD card and plug phone in to PC and see if it powers to download mode.

You can try saying you got some random message that an OTA update showed on your phone and you accepted it and it screwed your phone up. Just a thought coming out of left field

I had the EXACT some problem last week. I went to the repair center, said the phone was plugged in at work, we had a power surge, and afterwords the phone wouldn't turn on. An hour later...BOOM, new phone
I then went on amazon and purchased a usb jig and kept my phone stock until it came. lol

Every rooted owner should spend the 2 bucks on a USB jig. It's not the holy grail, but it's one more tool in your belt to potentially get out of a frustrating and time consuming situation.
I bought mine from here and got it pretty quickly considering where it came from ...

It will potentially force your phone into download mode from an "off" state when you otherwise can't so you can connect to Odin and get your phone's system restored.

I forgot to mention letting it sit when I mentioned this to someone else (or was it here?) about pulling battery and SD card. Also repeatedly press or hold power button with those out to purge any remaining juice in the phone. This stuff sounds crazy but ask any former OG Epic owner.. some of these tricks have brought phones back from the dead. There isn't a pinhole under the battery cover below the camera is there?
That last part was an OG Epic inside joke but the rest is worth trying

Phone will not charge!!

I am having a real problem here whenever i plug my phone into my wall socket or computer it will charge for about 5 seconds then say battery disconnected. I am on phantom hackers blazer rom v 3.7 and this just started happening yesterday when i installed 2 mods a battery icon and social hub. I restored because i thought it was one of the files but i still cant charge. Any advice would be greatly appreciated, thanks.

Anyone? I thought it may have been a software issue so I did a full data wipe, wiped everything and installed calkulins 2.8 and it is still doing it. Now sometimes it wont even recognize the battery when I try to charge it when the phone is off. Do you guys think its a failing battery or the phone? I should also not that the phone has always been extremely sensitive like if it I hit it by accident or drop it from even a couple inches it will reboot.

Night want to take it to sprint if it has always had issues

Well if you do have insurance they will charge you, but what you might want to tty is using a different charger.. my charger broke the other day (it wasn't charging my phone ) and i grabbed my old HTC charger. Hope this helps..

Ya I dont but I am taking it back to sprint later today to see what is going on. I am pretty sure it is either the battery or a loose connection somewhere in the phone because like I said in my earlier post this thing has always been extremely sensitive like if I accidentally put it down hard or anything it will reboot. Also like I said in my other thread it likes to reboot randomly when just in my pocket too. I also noticed whenever I try to run titanium backup it reboots 99% of the time before it finishes.

Well the thing is I can transfer stuff flawlessly on it. I took it to the sprint store the guy played with it for 2 hours and told me there is absoluetly nothing wrong with it so I dont know what to think. It has been running good ever since I got it back. I knew that would happen though as soon as ya bring something in to get it fixed it works flawlessly! The guy gave me a new charger idk I did try numerous chargers and they all said battery disconnected but this one actually does seem to be working so we will see what happens.

Battery Issue and random reboots

My Brothers phone is Rooted and its currently using the JoyRide 4.1.1 ROM. But as the title said hes having issues with the battery and getting random reboots. He said he would charge the phone to 100% and in one hour it would go down to 15% then shutdown. He would also be using the phone and just randomly the phone will shut off, and the only way to turn it on is to connect it to the Charger.
I'm wondering if he needs a new battery? should he go back to fully stock before going to the store?.. and how can i get him back to fully stock?
I've search but can't find a clear answer.

[psa] leaving recovery on too long results in hard brick

THIS HAS BEEN VERIFIED BY ME, AND JOKERSAX HAS TOLD ME ABOUT TWO OTHER DEVS WHO HAVE HAD SIMILAR RESULTS
This is a public service announcement saying that if you leave recovery (I left TWRP on overnight while restoring a nandroid) on too long, under certain circumstances not yet completely determined may lead your device to a hard brick. This has happened to 3 people so far, and want to avoid anymore issues with this.​
For more details on what happened I was flashing a V5 test build of my rom im working on adding aroma too where I got another syntax error to fix. It was about 11:30 at night, so I just started restoring from a nandroid, threw the phone upside down, and knocked out. When I woke up the next morning I checked the device and it was off in recharge mode- nothing too big. I then tried to boot and it ended up flashing the notification light and softkeys repeatedly, and did nothing else. I was able to get it into download mode, but LGNPST kept timing out. Then after trying several times with it timing out it wouldnt get into download mode. I then tried to just get anything to light up, and left it on the charger for several hours, and then gave up that my device was hard bricked. No data remained. I had to go to best buy and wait about an hour and a half for them to get me a new device. I hope everyone can avoid this happening to their device. It is a slow, but sure death reported by a few people.​

And to think I left my phone in recovery. for about 2 hours =x scared to even boot to recovery now

If youre phone boots it will be fine. I left it for about 8 hours or so.

This must be what happened to my first LGOG, I feel asleep running a backup. When I woke up it wouldn't boot. Thank goodness for Geek Squad coverage.

Does anyone know if this problem exists with clockwork too? I already fried a phone just making a simple backup using TWRP.
I'm using CWM now and made a backup and flashed a rom and my phone survived.

My phone also gets really got while in recovery mine also overheated exactly like the OP but mine came back to life I left it alone for a few hours then put it on the charger and finally got into download mode then recovery and restore. We definitely need to do something like timeout where after 10 minute the phone shuts off or something. Not sure it is possible but I like ranting lol

Only thing that could heat up the phone like that is the cpu core running at max.or spiking to max very very rapidly. Basically the soc with all the chipsests are not going into a sleep mode. I can see why all the data was gone and or damaged. I've seen something like this with other electronics.

I have not left recovery on long enough to experience noticeable overheating myself. I wish I knew how to fix the recovery myself though. Also as for making this a sticky (I read half the posts through email, and might have got this thread mixed up) mods are kinda inactive, so it will be hard for us to do.

I have heat up while playing games or streaming music, or leaving it at the lockscreen too long. Maybe undervolting it can fix it? IDR if joker's test kernel added it or not.
