[Q] Unrooted Evo won't boot - EVO 4G Q&A, Help & Troubleshooting

My friend has a completely unrooted, stock Evo. I'm not sure about the hardware version, and I hope it doesn't matter.
They were texting and using navigation with the phone plugged into a car charger, when it turned itself off and now won't turn back on. After a battery pull, it'll boot to the splash screen, but then shuts off again. After that, it doesn't boot at all.
I've tried getting it into fastboot, but I'm not incredibly familiar with the Evo. So far, no luck.
I have a rooted Incredible, so I've tried all the little tricks I've used to fix my phone.
So, any ideas? Bad hardware, bad software? Get it replaced?

My last Evo (I'm on my third one) was unrooted & would do something similar. At first it would just reboot itself, but then the screen would freeze & flicker and I would have to pull the battery then try to boot it up. Sometimes it would take 10 or so tries, but after it would boot up it would eventually do the same thing. At first doing a factory reset would fix it but then that stopped working.
If it's similar to my issue then it will have to be replaced. If your friend has insurance then they'll replace it for free since it isn't user damage. Until they get a replacement, try booting into fastboot & selecting reboot from there instead of just powering it on. That worked for me a few times.

I had tried the fastboot reboot, but it wouldn't even get that far.
Turns out, the navigation and texting had drained the battery faster than the car charger could charge it. After a full charge overnight, it's booting up fine. So it was fortunately a very simple problem.
Thanks for the reply, though.

[Q] Phone won't turn on

Last night I had dropped my phone from about a foot on a sitting-swing and it hit the ground. I have the black case from the sprint store on it. After that I attempted to turn it on and it just got stuck on Samsung loading screen with the genocide 2.0 logo below it, it then proceeded to be stuck there and eventually rebooted, this never seemed to end. When I attempted to plug it in to charge it the battery charging icon appeared but just has the loading symbol inside of it frozen, after many battery pulls and attempted clockwork-recovery boots failing I decided to go to bed. When I awake I went and tried to turn on my phone which immediately booted up into clockwork recover, fearing for my phones safety I backed everything up on it and then rebooted it. It seemed to work fine! It came on flawlessly and worked well. Throughout the day the battery seemed to drain extremely fast and then eventually died, having just gotten home I have found that the same thing is happening and it won't even charge.
Re flash the ROM then flash journaling on zip right after you flash the ROM then re boot & download you're apps fresh cuz you're data might be corrupted! Hit the thanks button if I've helped in any way! ;-)

I flashed back to stock rom to see if it would turn on, same thing happens, and I don't know if this is significant or not but when my phone boots up the buttons light up, then turn off, then back on again and stay on until the phone reboots itself or the battery is pulled.
EDIT: I have a strong feeling it's my physical battery that is causing the issues because it was working completely fine earlier yesterday.
Try booting in safe mode by holding power and the physical menu button until the phone gets to the lockscreen... Im curious to see if it helps because safe mode might help us get out of soft bricks? I wanna test this theory...
No it does not work, just get stuck at the Samsung loading screen. I don't honestly believe this is a software brick either because of the way it's acting, as I said in my above post I believe it's the physical battery and will probably be going to get it replaced soon

Help! My nexus won't turn on

Few weeks ago my phone just died. I mean, it just shut off completely. It booted up and all my apps were crashing - swype, terminal, chrome, skype, everything. I reinstalled them, and no issues since.
So today My phone kept disconnecting from 4g and not able to keep a signal. So I figured it was time to wipe cache and wipe dalvik. I rebooted into recovery, wiped both.. everything OK.
I turn it back on, I see "Google" then the screen goes black and that's it. Nothing happens. No notifications, I left it like this for a good 20 minutes thinking it would appear. Nothing. Dead.
Any ideas on what's going on with this thing? I can't not even tell you how sick of this phone I am getting. It's great when it's working or when the battery isn't dead.
My rom is TeamBamf (latest)
Any ideas?

You might have to fastboot back to stock

Or unroot. And reroot. It usually fix all the problems.
I can boot into fastboot mode, I can access it through ADB but nothing works. I guess my only choice now is to do a backup in CWM and then restore stock. The USB port is in bad shape. I was holding off on taking it to Verizon for a replacement because I want to get the replacement, sell it, and get the S3.
What would of caused it to shut off like it did and make all my apps randomly crash?

Phone won't turn on after rebooting to recovery...

I was going to update to latest AOKP, I selected reboot to recovery, phone turned off and never turned back on. I can't get into recovery mode either this is very odd any ideas?
This is very strange because this should not cause a hard brick... when I selected reboot to recovery it seemed like it froze for a second, but though it was just in the middle of restarting, then it just shut off. Why would that cause this, only thing I can think is maybe my battery drained... I have it hooked up to a charger right now. But like I said I can't get the phone to do anything.
Same thing happened to me with Galaxy Note from AT&T, I've been looking in several forums about this, but since the phone is not even charging the battery or booting, I'm loosing hope.
This suck ass

[Q] SPH-L710 reboots in recovery Battery, power button issues possible

I have read the other posts regarding the rebooting issues of the Sprint Galaxy S3 variant, but I seem to have a touch more difficult problem. My phone constantly resets and seems to be getting worse. It now will reset in the middle of recovery. I was able to wipe the cache and dalvik and then it started resetting even more frequently in recovery and made reloading the rom impossible. It even resets in the download screen. So it makes it impossible to use Odin and other applications. If anyone has any ideas let me know. I have a few possible options that I am pondering. The following is what led up to this if you need some background:
A week ago, I noticed that my battery suddenly was not charging when wifi was on. I turned it off thinking it was some glitch and reset the phone and plugged it in to charge. It said it was at 100 % some hours later. then I turned it back on again and within a couple minutes, it said it was at 22%. So I hard reset and then plugged it into the wall, but it was still not charging. I had go somewhere,so I plugged it into the car charger and enabled fast charge. I turned on my data and all the sudden it rebooted, lost my wifi password, but when it came back on, it was charging properly. So I thought it was just some odd glitch. Charged properly for days.
Then I noticed the phone starting to randomly reset maybe once very other day when texting. I was actually going to put on a new rom tomorrow thinking maybe my old one had become corrupt. Then it suddenly increased drastically tonight to where it was starting to reset constantly. I thought maybe the button was stuck, and pulled off my otter case to make sure it wasnt being pressed down oddly, but it continued. Then I went into recovery and was able to wipe the cache and dalvik before it got really bad and now it won't even let me stay in recovery for any length of time. I almost got a rom loaded when it reset and its been resetting faster than ever. Becoming unresponsive to button presses as well. Even when I could get into the recovery, it would keep showing "swipe screen to open," as the power button was apparently continuing to activate or the phone was trying to reset itself. And yes, I have tried a battery pull several times and then tried to get into recovery, only to be booted out right as I see the recovery screen if I get there.
So that is my problem. I can't flash odin or anything else as the phone just keeps resetting. Part of me thinks to get a new battery and try to see if that doesn't solve my issue, as maybe the battery is causing the phone to reset? But part me is also thinking maybe the power button has gone sticky suddenly? It won't charge it seems as the red light will not come on and it keeps resetting before the battery charging icon can even come up. Any help or advice would be appreciated. I am leaning towards the battery going bad suddenly and shorting out the phone. I now have the battery, which last I saw was at 48% (It was charging when this happened), out of the phone and am waiting till morning to hopefully pick up a new battery. But I would appreciate any insights into this issue.
Thank you very much
Same issue
I'm having the same issue described above with the S3 constantly rebooting. I can get into download mode but it restarts a few seconds into the flash. I have tried a different battery but that did not solve the problem - I am also thinking it's a power button issue... any suggestions?

I just had my phone replaced for same reason ( Thank god for insurance) Download mode would last about 5 seconds, Recovery would do the same. I managed to get a stock restore with flash counter reset to boot as i was walking into the Sprint store for the techs to look at this lol.. Same exact thing happened on my S2. Power button is done. If you have INS call and get it replaced (Took me about a week for new phone)
I read some post on possibly using Samsung Kies to flash a new ROM, but that was for the international version. I would be curious if anyone has ever tried this or if its possible to replace the power button with a part replacement? I have ordered an S4 but this time I will make sure to use the home and left touch pad more often to unlock the phone and save wear on the power button. I wold still be interested f anyone has found a fix for this.

So after looking around, I am pretty convinced this the power button,as people describe on this question. If you don't have insurance, I see there are selling replacements or you can pay someone to replace and fix the power button fairly affordably on ebay. I might go the second route, as I want it fine right and the man had a 100 percent rating positive, and I dont really know what I am doing lol. Thanks everyone for your answers.

Phone Turning off by itself.

So I have this weird issue with my HTC ONE M7 for a few days now. It would turn off by its own when I was using it but I'd just turn it on and it will work again. I thought it may have something to do with a bad app or the rom might be acting up. Anyway I ignored it since turning it on was a minor inconvenience and I needed my phone functional. Today whilst using GPS, the phone suddenly went dead on me. Every time I boot it up, it passes the initial HTC screen but then doesn't boot into android. The screen goes black and the phone turns off by itself. I went it recovery, wiped dalvik and cache thinking it was an app causing a boot issue but that didn't help. The problem continued. I already had a backup so I went ahead and tried restoring it. It worked the first time. But the phone still won't boot. It would turn off automatically. Then I tried reflashing it with the backup. This time the phone would just turn off as soon as the restore process started. I finally got tired of it and decided to reflash with a new rom. The flash went fine. But lo and behold the same issue again. Boot animation and then black screen with the phone completely turned off.
I thought it might be the battery so I plugged it in to my laptop USB. It booted but when i was setting up android, it would just shut down again. Then I connected it to the wall socket thinking the phone will get more juice. This time around I was able to set it up. With the phone connected to the wall socket all was working splendidly. Please note that during all this time the phone was at 100% and there were no drastic falls in the battery levels.
As soon as I disconnect the phone from power, any power intensive operation shuts it down. I have been in recovery mode for 2 hours now and the battery hasn't even dropped by 3%.
So the question is, What the hell is going on? Is it the battery, is it phone's hardware or is it a software issue? Any help would be greatly appreciated. Cuz if it's something that can't be fixed, I have to start thinking about getting a new phone then. THANKS so much for bearing with me! Cheers!!

if you are s-off i would suggest doing an RUU and starting fresh. Its hard to pin point a problem without having the device handy and trying some things. The RUU will let us know if its a software problem or if its going to be hardware related.
Hey thank you so much for replying. I am s-off. But would going back to stock re S-On my phone? And how do I do RUU? Thanks again.

Do not s-on! Just run the ruu eye dottat made
Installed RUU. The problem is still there. The phone can stay on for hours in recovery without a charger but as soon i want too boot into android it shuts down. It only boots up if it's connected to a charger and that too a wall socket not a usb hub cuz it goes some way into the boot process and shuts down half way. I am pulling my hair out here. Dunno if it's the battery or the mother board.

If ruu still has issues. It is motherboard or battery. From the symptoms, it sounds like battery as the phone needs to have some juice to fully boot the phone before being able to run off the charger.
