I noticed a strange problem with my Nexus 5. It starts to hang or restarts on its own. Sometimes go in to continuous boot loop. I could not differentiate why it would do that. Sometimes it worked flawlessly for hours. Then I realized that when it's charged off my computer USB power it works smooth. It works fine for sometime. But after few minutes of idle time or quick usage session freezes the phone and it re starts and keep going to boot loop, even after wiping cache. After a few attempt to wipe sometimes it starts without external power help. However, when attached to USB power it just starts without any issue.
I have done factory reset a few times. Unlocked my phone and also installed TWRP with Pure Nexus. The behavior hasn't changed much.
I think this is hardware issue. Could be a battery.
Can anyone provide a detail on how I can find issue?

As of last night my tab 2 (p3100) has been playing up, have it running a pac rom, not updated in a while but all was working fine. Now when I do get it on, it lags a lot on home screen, can only really access anything for about 30 seconds before its practically unusable. When I try to power off or reboot it begins the process but ends up freezing, only way I can get it properly off it to plug it in to charge and then hold power for ages. Then getting it on again takes ages. Only thing I recall doing prior to these issues was installing the peel remote earlier that day, maybe just a coincidence but after that it all went wrong. I've just tried a factory reset and data wipe, seemed to initially solve the problem but after a few mins back to the same issues, any ideas?

Try flashing another ROM, like CM 10.2 or one of the stock-based ROMs. Make sure to wipe data, system and cache before flashing. If the issue still persists, try restoring a backup that you know worked.
Will give that a go, thanks.
Hello all,
Today my Verizon S6 (on CleanRom 1.5) started to keep rebooting. After it boots, I can use the phone for less than a minute until it reboots again.
Here's how it began to happen today, if it helps.
- I didn't plug my phone to a charger last night, and when I woke up the phone had like 0%~1% battery. The phone died soon after I picked up the phone.
- At the same time I turned on the phone, I connected it to the stock charger.
- I used it for like 1-2 minutes, and the phone seemed to get confused whether it should die again or not (at 0% battery level)
- Then the phone decided to die again, and keeps rebooting itself.
My guess is something related to booting, initializing, or battery might have gone wrong. Also the soft button lights get never turn on.
Now I cannot use the phone really, as it dies like 30 seconds after I swipe the lockscreen.
- I tried to boot into safe mode, it didn't help.
- I wiped cache partition, it didn't help either.
The last thing I would like to try is to odin CleanRom again (or factory reset) but I would like to try other things first because I cannot even backup the data as it keeps rebooting. Odin will wipe all the data in my phone.
Any help or suggestions guys?

The OE2 tar file shouldn't wipe your phone as it is not a full wipe tar. I don't know if your phone would do it with it's reboot problem but a dirty flash of clean rom shouldn't wipe your phone either. However, a reboot during the middle of either of those would not be good. Flashfire does seem to be able to keep a phone from rebooting once it gets going or at least it has for me when I have been caught in a bad way before.
Problem Solved!!!
Thank you Tulsadiver for your suggestions. But is it okay to do odin without wiping anything?
I almost gave up after struggling several hours and thought about doing a factory reset, but the problem is solved now.
I found it weird that the soft key lights never turn on, so I thought that there might have been something wrong with the power management. So I turned the ultra power saving mode on (fortunately the phone didn't reboot before I did that), and it didn't reboot itself. I turned it back off then now the problem is gone!
I am happy with it now, and this might be one of the things to try if you experience a random reboot.
Please help my phone is confused like it is blinking lg logo but not getting on. In charge it gets on but in few seconds it gets off.
I think you are in soft brick state for some reason.. Did you try to do anything prior to this situation?
How did that happened? Similar issue happened to me, heres my post from other thread:
My H955 suddenly rebooted and it keeps on bootloop. It turns on fully and after 10-30 seconds (the hotter it gets, the less time it stays booted up) reboots again. After I left it to cooldown, there was error that root is gone or smth like that, and I had to agree to EULA and terms&conditions but the phone rebooted again. Maybe some kind of update was pushed in or whatever. This is the first time for me to happen. I have not installed new apps or mods on my phone like in two weeks.
Btw, seems like this is soft reboot, because there is no sounds and it didn't asked for SIMs PIN. I guess it has something to do with xposed..
I have used this method http://www.hard-reset.mobi/lg-g-flex-2-hard-reset/#to do factory reset. It seems to work, however phone still reboots. @mnshkpr8 try this to do factory reset, maybe this will help you.
Later I will try this http://forum.xda-developers.com/g-flex2/help/to-unbrick-g-flex-2-ls996-t3286105
Hi. I have similar problem here.
My phone wont pass LG logo if without charging on, the phone keep booting.. And if i charging on the phone just works fine, but if i plug out the charger the phone just turn off and restart again. Mine still using stock rom. Any suggest ?
This happened to me today as i edited one system file so I could get any app on split screen, I used flashtool and flashed the same kdz in normal mode, It flashed and everything is normal again.
any solution to this?
I'm a serial lurker here and hate to ask for help, but want to reach out (and finally start hitting thanks).
My N5 was on MMB29S 6.0.1, SuperSU version 2.65 for root, xposed v79 (gravitybox, APM+, snapprefs), and ran perfectly fine up until a few weeks ago when I started having issues. Apps would sometimes FC, and (not always right after) system would hang and then reset. Sometimes the screen would go black but notification light still would blink.
Upon reset, it would either (a) get stuck at google screen and bootloop or (b) get stuck at some point during the boot animation. If the phone did start, it would usually work for a variable amount of time - minutes, hours, but usually not more than a day. Other times, the phone simply would not start and required a slowly increasing amount of time to boot while holding down the power button, sometimes not even booting at all. The phone would sometimes be unresponsive to holding the power button for up to 12 hours before the phone booted up again. Not saying I help the power button that long, but tried frequently over that period of time.
Over the past few days I've taken to troubleshooting in the ways I could think of and what I've read here on xda (I can link to any of the threads if you are curious) and the rest of the web. I started by disabling xposed, restoring stock boot image and removing root, and have since flashed completely to stock MMB29V and have followed the advice of @audit13 to even flash the userdata.img file and perform a factory wipe before booting the phone for the first time.
Nothing works. Even after being bone stock now there are still random resets, with the power button having to be held down for quite some time to power back on (if at all). The only difference is that it hasn't been getting stuck on the boot animation when it does power on.
I'm a bit sad, and realizing that this is probably the end of the line for my venerable Nexus 5, but any help/suggestions are welcome. Thank you in advance!

Could be a power button issue that's causing the resets? Have you tried removing the motherboard and quickly pressing and releasing the power button several times in a row using more pressure than normal?

I have yet to try that, but will try that in the next couple days. Might not get to it tomorrow as I have an upcoming exam.
I'm not completely sure if that's it though since the system seems to hang/freeze before powering down, but I can give it a shot. Thank you for the idea!

As a last resort I could try that -- how do you think that would solve my issue? Thank you!
Maybe a battery problem? I'm just guessing at the different things that may cause a boot problem or resets.
Under a variety of circumstances (charging, safe mode, plugged into computer, etc.) I have tried to use my phone but whenever it is turned on to any degree, it consistently restarts itself after a couple minutes.
At this point, I don't even care if I need to buy another phone; if I can fix this? Awesome! If not, I really just want to save my data.
It is not in a boot loop - it functions fully with no error until it restarts.
EDIT: I found some suggestions about wiping the cache partition (I believe that's the wording) but that didn't help at all.
EDIT2: Development; the phone stays on as long as I constantly touch the screen
