Reboot loop after booting

Can anyone suggest a troubleshooting method without a factory reset. This is what I am experiencing:
Everytime I reboot the Sensation will boot up and go through the normal process. About 3 or 4 minutes it will just reboot. Often when this happens I note that I don't have to re-enter my pin (a clue?). This rebooting will go on repeatedly but eventually (if I leave the phone alone) I will at some point end up with the phone up and running.
There are no random reboots, it is only this situation that causes the problem and it's obviously some point 3 or 4 mins into the process that is causing the problem.
I've noticed that if I reboot to recovery and then select reboot from there it is usually successful.
I am s/off via wire trick method, and rooted. recovery is 4 ext and I am still on stock rom.
I'd like to find out what is happening at the point of the reboot, is there a good way to do this?

Hi,
Have you installed a new ROM recently?
Did you fully wipe the phone before you did this?
If not,try re-installing the ROM you are on.
No wipes.
You will not lose settings or data.

What I noticed is that the problem didn't exist when rebooting from ADB or fastboot either.
Anyway your suggestion so far looks promising. I've tried a normal restart from the phone and a battery change both of which would usually end up with the rebooting problem. Both of these tests haven't caused it so I'll keep testing but thanks for the suggestion.
What is does the Dalvik cache do and how would this have caused this kind of problem? I'm interested in the whys. The problem appeared soon after installing a couple of things as I remember and I did try to backtrack without much success.

No I've not installed any Roms, I'm on stock.

Revived thread - as it's happening again
I'd like to revive this thread - perhaps I should post a new one but since it's here ...
This problem has returned with a vengeance. It took me about 3 hours of fighting to get this phone to stop rebooting. It seems clearing the dalvik cache isn't a solution anymore (if it was in the first place).
What I've observed is that if I take the sd card out it doesn't reboot. When the card is in I have several shortcuts on one of my home screens which often will not refresh for ages (ie. android icons for anything moved to sd card). When the icons start to appear the reboot will happen shortly after. All the time I'm waiting for this to happen the phone is very sluggish.
I don't think this is an incompatible sd card but maybe it is, however, if I can get this to stop rebooting then all is ok till I attempt another reboot.
Ideally I'd like to track this down to find out if there is an app which is misbehaving. Are there any tools that can help me do that.
Any suggestions would be most welcome.

Backup all your data and do a factory reset
This problem might be due to 3rd party app as you phone without sd card dosent reboots
Might be some of ur app is seriously miss-behaving
After a factory rest install each app n check ( I know it's time consuming)
Hit thanks button if you find me helpful

Yeah hoped to avoid that for 2 reasons. 1) It's a bummer 2) I won't know what the problem was / is.
I did do a factory reset after backing up data via my recovery. It seemed to be ok but I had nothing on SD at that point. I loaded a couple of apps and moved them to sd and it still didn't happen. The I restored the data and it was back to the same problem.
I may have to go with your suggestion but I'm going to lose some data as I can't back up selectively (so it seems).
Is there a logger I can use that starts at reboot. If I could find out exactly what it's doing when it decides to reboot I might nail the app?

hi
greetings
to find the problematic app might go tough you will have to install each and every app and check after that
try installing all the trustworthy apps before eg. file manager,fb,twitter,gmail etc then check once again ,after that install single app at a time

[Q]Phone rebooting (PAC ROM)

I'm on the PAC ROM. Always worked great, with some minor issues. Today, I received a message on Whatsapp and, suddenly, trying to open it, both from the notification drawer and from the app drawer, caused phone to reboot. I tried killing the process from settings, it rebooted before loading all the running apps. After that, I've not been able to run anything without causing a reboot. Why is that and how can it be solved?
EDIT: I understood it is Smart App Protector's fault: every app works fine except that and all the locked apps. Trying to uninstall or stop it causes the phone to reboot, as well. Any idea on how to solve this?

Try wipe data/factory reset.
if the problem remains unsolved:
re-flash your rom (clean flash).
you can backup your data through recovery.
regards

Thank you very much, it works now. But Google Play is stuck on the loading screen... Any solution to avoid reflashing?
EDIT: Nevermind, it is magically running again.

Yup, this is because Google play have to update itself and change interface directly after each data wipe

Help: Nexus 5 Rebooting randomly and going into bootloops

16 GB black Nexus 5 on ART with stock recovery, stock kernel and rooted using CF's autoroot and bootloader unlocked. The phone was running perfectly for the past 3 months.
Now it has started to randomly reboot all the time and goes into bootloops which take a while to recover from. It seems that the power button is super sensitive. Even touching it mildly brings up the power off option. After reboot the phone went back to Dalvik runtime from ART.
I've been running Dalvik every since. I've uninstalled most apps. But the phone keeps on rebooting again and again just randomly in the middle of tasks. After this the phone goes into a boot loop until it boots successfully. It's almost impossible to use the phone right now, because the reboots just happen more and more frequently.
I've tried wiping the cache, uninstalling apps etc. Nothing has helped.
Any suggestion? Thanks in advance.

Sounds to me like a hardware issue-as if the button is partially depressed at all times. You could try popping the back off and blasting around the button with compressed air. Another option would be to RMA.

Thanks for the quick response. I don't want to mess around with the hardware of the phone. I think I will go the RMA route.
Do you have any suggestions in terms of the best way to backup the phone? Do you think a factory/data reset of the phone might help before RMAing?

I'd factory reset just as a precaution as your phone probably has some personal info on it

Yes. I will definitely factory reset before RMA.
Any idea on the best way to backup the phone content? Should I flash all system files for factory reset or just use the phone's menu?
Thanks.

Upload photos, music and videos to drive, dropbox or to your computer with usb. Then depending if you're rooted or not helium or titanium backup for app data. Me personally I'd just flash all files cause it doesn't take long to do so. Good luck and hopefully your new Nexus gives you better luck

Sounds like it's a hardware issue with your WiFi/Network chip

bricked (?) with "phone is starting"?

this morning, my gps wasn’t working and i did a reboot, since then my phone won’t start anymore. originally: bootloader unlocked, twrp installed, magisk as well.
after typing in the security pin, it was stuck. i assumed there was some problem with that, so i went into twrp and deleted those lock settings files, reboot, now i’m at "phone is starting" after each reboot now and i can access settings and basic stuff, but no home or anything, and tapping on system update tells me that the app is not responding ("settings keeps stopping"). booting into twrp asks for a pin which does NOT work anymore (neither my original one, nor 0000 or default_password).
i used magisk uninstaller (sideloaded), and reflashed what i assumed was an OTA-zip from the oneplus website, so i’ve got stock recovery installed now (bootloader still open), but otherwise not much changed - after booting i can basically only access settings (from the quick settings bar), nothing else works.
i ASSUME it has got something to do with not being able to decrypt data anymore. i also assumed i can just reflash the 2gb-zip from oneplus and that would include a fresh system/boot img and deleting those lock files from twrp would remove decryption, but i guess i was wrong.
other that formatting data now .. any recommandations/suggestions? any help would be greatly appreciated. :/

could be stock launcher is frozen or disabled?
it did this to me, even if I had another launcher.

thanks for your guess - but, no, not disabled, i can see it in the list of apps. the only app "disabled" was the oneplus gallery, switched that back on, no effect ..

tried that, didn’t work. and even after a "factory reset", starting from the "hello!"-page from scratch, everything stopped on the next page ("just a sec ..") - so i guess there was something seriously wrong with my data partition. not sure why though.
after formatting data (and crying during those few seconds) it "worked" again, now, and fortunately i had some kind of app backup at least, but ..
yeahwell.

very strange
maybe the restricted. XML file was stuck
no point trying since you formatted

four hours later, fresh setup - it’s starting to happen again, sudden "hangs" and "phone is starting .." out of nowhere, then "system ui is not responding", force reboot, .. working right now, but there’s something really fishy and i’m starting to assume it’s a hardware thing.

I'm having the same issue after rebooting to fix gps/mobile data issues. Any other solutions?
