[Q] Epic powering itsself off! help? - Epic 4G General

Hey guys just wanted 2 start out by teling you that I am using dk28 and the newest viper rom. My phone had been working just fine until the other night. Then all of a sudden every time the screen times out the phone will power off. In order for it to power back on I have 2 pull the battery. The weird thing about this though is if the charger is plugged in it will not turn off.
I have already tried reinstalling the rom after a full wipe of the phone. I have also tried a different rom. Should I flash back 2 stock and see if this continues? If so can anyone provide a a link for the files needed in odin to do so.. thanks in advance!

[Q] Phone wont power on, or boot to download mode or recovery

I'm not sure what the heck happened. Flashed cwm to my sph-l720t and all was groovy. I was able to install CM 11 and update to the latest nightly. A few minutes ago the phone just powered off and it won't come back up. The battery is fully charged.
I can't power it up in any way with out having to take the battery out for a few minutes. After that I get one shot at powering it on or entering recovery mode.
If i hold vol down and the power button it enters the download mode but then shuts off. The same thing happens with recovery mode and booting normally.
Any ideas?

Try replacing the battery. Maybe borrow a friends battery just to test if that's the problem. My phone used to power on fine and almost full battery. It would shutoff suddenly so when I powered it on again it would show the battery still almost fully charged. This happend a few times and sometimes I noticed the battery level would drop for example was at 87% it shut off, powered it on and now showed 42%.. I replaced the battery and everything was A okay

Thanks for the reply. Unfortunately I've tried this already. Still no joy.
So I ended up bringing the phone to sprint. They said it was a software issue and gave me a new one. He also said there was a bad update or something but i wasn't on a stock rom so i'm not sure how true that is.
On the last device I rooted and installed clockwork mod using flashify. I then restored my backup of my old sph-l720 (non triband) and it worked for about a day then at some point it died and was stuck in the position mentioned in the OP. Does anyone thing that the phone bricked because of my restore method or because of some weird circumstances on sprint's end? I want to restore but don't want to brick it.
If that backup came from a non tri-band l720 S4, that is what happened to your l720t. Do not restore that backup to your new one if it is a l720t

Power won't turn on after flashing Alliance ROM. HELP PLEASE!!

So I had Alliance ROM on my phone to begin with and I downloaded this http://www.alliance-rom.com/communit...able-nd7.9054/ and installed it in safestrap recovery mode. After the file was finished installing the phone turned off. (I thought it was going to restart and well that never happened, The phone doesn't even turn on. I've taken the battery out and tried to power it on, I've tried taking the SIM and SDCard out and turning it on. I've left it plugged in and charging and tried turning it on, I'v plugged it into a computer and tried it that way. Nothing that I have tried has worked. If anyone can please help me get this working I would HIGHLY APPRECIATE IT!! I use this phone for work and to keep in touch with my Daughter. Thank you ahead of time for any ideas that may or may not work.
First thing, the link you posted doesn't work. There's dots in the middle. Second, if it won't even boot to the Galaxy S5 screen before the boot animation that could be one of two things. A. It installed a custom boot loader not meant for your device that could be fixed if you could boot to download mode, which you can't. Or b. your phone is physically broken and you'd need to take it to Verizon to get fixed. Right now it's probably the second, but I have little clue as to the ROM you installed.
This has been pretty much answered for you in your other thread. You put a rom meant for note 2 on your S5 , probably not going to be fixable. But your ONLY chance is to get the phone into Download mode. Then odin a stock S5 ROM. No longer any need to panic you have brick so...At this point remain calm and move slowly so you don't make another mistake hope you get lucky.

S4 bootloops on every rom, even after Odin stock flash.

Hello, I am having an issue with my S4.
I was having random reboot issues and my rom was quite old (omega 30 or something) so I decided to update my phone. I flashed stock from odin, then installed TWRP again and tried flashing roms. Roms previously would boot up to the point where I would setup android and then reboot. Now my phone seems to reboot almost directly after the "Samsung Galaxy S4" logo. Some roms have let me boot into the android setup but once the Mobile Network seems to try to connect, the phone reboots right away.
I have tried flashing 3 different stock roms thru ODIN and they all have the same issue. I have tried clearing cache/data in recovery but it hasnt helped.
Does anyone have any suggestions or advice? Thanks!
Might be a power button issue. A friend had a similar problem. The phone would boot and work for some time and then turn off.
At some point it just wouldn't turn on anymore.
It was the power button.

Thank for your reply!
Just curious, if it was the power button, wouldnt my phone also restart in recovery and in download mode? In both of those modes, there is no issue. I'm worried that I flashed a modem incorrectly some time in the past and that could be casuing me issues. If the stock rom passed in odin, shouldnt the modem be working correctly?

Stock roms have modems and bootloaders included. So it must be something else.

It's very odd. I have no problems getting into recovery or download mode, but absolutely anything I flash will not boot with any reliability and not for more than a few seconds. I was able to flash Omega 42.1 and that worked for about 30 minutes yesterday and then began bootlooping as well.
I have no ideas.
I hate when people solve their problems and don't follow up on their own threads so here I am to post my solution.
Turns out my battery was slightly swollen and causing the battery to disconnect and make the phone restart. I noticed this after a bunch of various testing with the phone plugged in and unplugged. The phone would work fine plugged in but within a minute of being unplugged it would turn off or reboot.
I purchased a new battery and have had no problems at all since, everything works great. When I compare my swollen battery to the new battery, you can see it is slightly swollen but hardly noticeable if they are not side by side.
Anyway, for anyone reading this thread in future, my solution was to replace the battery which had swollen.

Phone turns off after screen turns off.

Hi Guys,
I need help, I have a Note 4 SM-N910P (Sprint unlocked), For past few days I'm having a problem with my phone that when the screen turns off the phone turns off too and I can't turn it back on by pressing the power button or any other button. I have to take out the battery and then turn it back on.
I was using Custom ROM, so I thought that it may be causing issues. So I flashed my phone with the stock ROM, I made sure I wiped out all the caches and system files... but it the same issue.. The phone works perfectly fine till the screen is on. But the moment it turns off the phone just won't open.
Currently using Stock Marshmallow 6.0.1
Please help..
Thanks,
Asim

Battery?
Sent from this galaxy
Does it work fine in Safe mode? If yes then some present software might be the cause

Nope.. I have two different batteries, tried both of them and still the same issue.
Even when i restart my phone it does not restart. I have to take the battery out and then wait for few minutes and then I reinstall the battery and turn it on.. Sometimes, it goes in download mode and i see a message that says "normal boot failed".
