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.

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

Received update last night... But...

Phone has been updating since last night and it's now morning. Any idea what the update is and if I can just do a battery pull? I need my phone today and I don't know if this update froze my phone or what...

Mine was in download mode this morning too, thought it was odd. Waited a bit and then rebooted since it didn't seem to be doing anything. Phone appears to be alright...?

I'm guessing it's the mediahub update.

NEVER do battery pull from download mode (not good for any mode tbh).. REGARDLESS OF CONNECTED STATUS...
This is how **** gets corrupted.. simply hold power for approx 10 seconds, phone will abort state and reboot

Oh yeah definitely, like Doug said. Hold power button to reboot. I've never done a battery pull on this phone.

Good to hear, but as doug mentioned above, should one really pull their bat in this situation?

If it's in download mode, but stuck I suggest plugging into PC and Odin a stock tar just to be safe. You'd hate to lose download mode due to a bad flash, just in case.
Sent from my SGH-T989 using xda premium

The download mode of the phone I believe backs up boot to ram before flashing, so holding power and forcing abort I do believe restores this if modified, shouldn't be able to loose odin/DL mode or recovery even from stuck OTA..
Unless your a n00b and battery pull, ehich in this case you deserve a paperweight anyways

What was the update? Media hub or something else?

Yes, It was my nephew's s3. He was blindly flashed it, now He asked me to help him, and I am asking any one in here know how to get it power up and into download mode.

I think that flashing the wrong radio version could fry the whole thing dead permanently.
However, if you can get ADB to recognize the device you may be able to get it working. See if you can get adb to recognize the device at all, if you can there may be hope.

Sorry many that have flashed international have been hard bricked if they can't return on. Mskip has a toolkit but if it won't turn on then it's hard to flash though.

Does any screen come up? If it's hard bricked, just bring it to the store, and show them. They'll probably try a new battery, and if they can't boot it up, then they may replace it.
Worst case, they say they won't replace it cause you messed with it, and you're back where you started.

Cause the USB dongle will put you straight to download mode. From there you can flash the proper ROM.
Anyway, if you can't get in to download mode, can't boot up to anything, and especially if ADB can't find your phone, then you might have just gotten yourself a very expensive paperweight.

I did the same thing, quit wasting time, you need a Jtag service period, if you can't get into download mode, Odin and Adb IS NOT going to work. It will not see the device. Go into device manager, if you see this QHSUSB DLOAD, you are seriously bricked, only Jtag can help it. The usbjig will NOT work with this issue, I have tried.

This is the correct answer, Jtag or return are the only options.

Just bought a S3 from Craigslist -- May be bricked?

Hi,
I just bought a Pebble Blue S3 from craigslist without checking it out properly. (I know, shame on me). The phone is in physically mint condition, the water damage tab is not red and there are no signs of dropping.
The phone's screen does NOT turn on. When I hold the power button to have it load up normally, I can hear the T-mobile jingle and then a constant blue indicator would stay on the top left corner.
I have tried flashing it back to stock through download mode (Power, volume down, and home --> volume up mode) and it seems to make no difference to the screen's issue.
Flashing it back to stock might have made it worse because I can't even access the phone's internal memory through USB anymore.
Any help towards fixing my screen would be great!
Thanks.

So out of curiosity how much did you pay for a phone that you did not check to see if it turned on?
Sent from my SGH-T999 using xda app-developers app

I paid $250 for it, came with original box and accessories. I thought it was too good to be true, and it seems that way. At worse I can probably break even and sell it as-is.

Is the battery low?

What does windows report it as in device manager?
If you can get to download mode it may not be hard bricked.
You could flash twrp recovery with idin, then boot recovery and try flashing something from thrre.
Also twrp has a builtin file manager so you can try to see if you can find sny problems that way. (Look for logfiles)
Are you sure its an SGH-T999?

I was able to access download mode by clicking around in the dark.
Positive it is a SGH-T999, before I flashed the stock PDA in ODIN, Windows Device manager would list that. How do I flash TWRP? Do I need the screen to do it?
Oh the battery is fully charged.

Here is the thread for TWRP. But you get to download mode by starting with the device completely powered off, then pressing the volume down, home and power button at the same time until it powers on. I dont understand what you meant by "I was able to access download mode by clicking around in the dark"

Button mashing I guess?
And just fyi, to boot recovery from power off
Hold volume up, home and power. When you see blue text flash on top of the screen release.
Also, flashing recovery in Odin will trip the flash counter. Prob doesn't matter considering the situation, but just so you know.
Sent from my SGH-T999 using xda app-developers app

If you can get the phone in download mode, odin back to stock. Then boot into recovery using power +home + vol up and do a factory reset. This step is important. I borked my phone with a bad jb install and using odin on its own doesnt completely reset the phone. Using the factory reset fixed this in my situation

By saying I'm able to access recovery mode, I got in by basically doing the sequence of buttons, without seeing any display on the screen. I know it is in download mode because it reads on ODIN.
No matter what I click or what mode it is in, the screen is still completely off. Sorry for the confusion.

I've had Samsung service my SGS1 that I bought off Kijiji while it was still within its one-year warranty. It doesn't just apply to the original owner, just call them and tell them it was a gift, they'll ask for the phone's IMEI, and then they'll be able to tell if it is still within its warranty period.
