Hi
I have a problem with my Galaxy S2 where it's in a constant reboot loop and the only way to stop it is by taking the battery out.
I'm sure that if I do a factory reset it'll go back to normal.
The problem is, I can't back anything up because as soon as the phone boots up it restarts.
Is there ANY other way to back up my photos and videos etc?
I have NOT rooted the phone
Cannot find any solutions online
I'm currently having this problem too. A couple of days ago it kept rebooting in a loop. I took the battery out and left it for a while, then let it charge. It seemed okay afterwards. Now today it keeps rebooting, and the past couple of days it has refused to charge the battery because apparently the battery was "too hot or too cold" (don't quote me on that) so I'm very confused. Just now though the battery was about half-charged and it still went into the reboot loop.
Something else you should know is that like the OP it has the stock OS on. It isn't rooted or modified. I don't want to factory reset it because I have spent so much time customising it (with apps) and it would be a pain in the ass if the problem still existed afterwards. One thing I must ask the OP is, did you recently get a 64GB MicroSDXC card for your S2? I ask this because I did a couple of weeks ago and it's been working fantastically and was said to work fine with the S2, but I'd like to explore any possible reason this reboot loop is happening.
Thanks.
Edit: To confirm I deleted the cache and this didn't help. I don't want to hard reset...
I've just done a factory reset - I hadn't realised that it only affects my apps and not my files.
The phone is ok now.
Okay, so, I know I am not the only one with this issue. At the same time I know not ALOT of people have this issue. Lets get right down to it, I bought a Note I717 from someone who claimed that it was stuck in a bootloop. Well, I turned it one when I got home after doing a factory restore and it came on and stayed on. I thought I had fixed it until the battery died.
Symptoms:
Boots up fine
Stays on for around 2 minutes
Freeze then Reboot
Happens every time. I have tried to restore stock firmware, have tried custom roms. Have rooted it, unrooted it. Battery holds a charge and is perfectly fine. Power button is NOT stuck.
There have been 2 times I have got it to come on and stay on for like 12 hrs then it will freeze and cut off, then start the rebooting sequence all over again. Anybody think they can help me out?

whn i had a similar issue, the answer turned out to be that i was overclocking. if you are overclocking/undervolting it can cause random reboots.
The other day, my phone died midway through a call. When I tried to turn it on, the 0% sign showed up meaning it was completely dead. I had to urgently make a call so 30 mins later, I held the power button again, turned it on, and the phone went to the white HTC screen and then turned off. I finally got home and connected to my phone to my charger after. I let it charge for a bit then turned it on. I knew something was wrong when my phone was hung on the red Verizon boot logo for a while. Minutes later, it went past the Verizon logo and a pop-up appeared that said optimizing app 1 of 44. I thought this was odd because I already got the MM update about 2 weeks ago and since it updated, I never saw that message ever until now.
Once my phone gets past that and finally boots to the homescreen, I realize that a lot of things have gone wrong. First, I got signed out out of all my accounts (Whatsapp, Spotify, Instagram, Facebook, etc). On top of that, my call history was cleared, all my text messages were cleared, and all my contacts that were saved on my phone storage were gone. In addition, I also had to re-update a lot of apps including the HTC ones that you have to upon the MM update. Finally prior to those whole thing happening I had 10.7gb of free space. After this episode, I lost exactly 1 gb of storage and only have 9.7gb free.
I don't understand what could have caused this or why I lost all this data on my phone. Moreover, it doesn't seem like anything was deleted but my phone is just not reading anything that was already there.
mine just did this exact same thing after shutting off from a drained battery. It's like the data partition or whatever got wiped. Right now trying to log back in to everything and set EVERYTHING back up again. This sucks.

i came here for the same thing. mine happened around the same time. only thing i can add here is that my storage is almost maxed out on the phone. makes me wonder if that had something to do with it. but then this happened to two other people around the same time. very weird.
The exact same thing happened AGAIN! I was at the gym listening to music and texting some friends while my battery was at 15%. Went from 15% to 10% in a matter of mere minutes and then from 10% just shut off. Couldn't charge it until I got home so I just kept it in my pocket. Got home about an hour later, put it to charge and then turned it on when battery hit about 10%. Same damn thing, got stuck on the Verizon boot logo and then the dreaded Optimizing Apps message showed up. Once it finished, I was logged out of all accounts, updates to system apps were gone, and widgets/BlinkFeed were gone/reset. And just like last time, suddenly 1GB of storage was gone.
Literally un-freaking-believable. I dreaded that it would happen when my phone shut off and yep, my fears were right. Going to do a factory reset once I backup everything. From there, I am debating whether to replace the battery or replace my phone. While it sucks that it happened to you guys as well, I am somewhat glad its an HTC issue and not just an issue with my personal phone.
Same thing happened to me at 40%
This was recently brought up in the viper rom thread, could be of help.

Your battery needs to be reset. Hold down POWER + VOLUME (can't remember if it was up or down. takes about 10 seconds)and let it keep resetting and keep holding it for 3 minutes. then let go.
It'll fix your battery so that it drains to 0 instead of 13, but it doesn't fix the weird pseudo-reset problem. It's a known issue and many people are struggling with it. My advice is to set EXTREME POWER SAVER to auto-on at 10%, and if you ever see it that low, just turn it off yourself until you get a chance to charge it.

Same thing has been happening to me since the MM upgrade. Before that I had NO issues with my battery so I find it hard to believe that my battery is the problem.
After the third time of this happening I finally decided to to a factory reset. This did not help, phone continues to die anywhere between 15% - 30% and revert some of my settings back to stock.
This is driving me insane as I rely on this phone for personal and work use.
Decided to call HTC support today, I did not expect a solution but wanted to make sure it was reported. Of course they had no idea and claimed to have never heard of this issue.
I am guessing that since the M8 is over two years old we wont be seeing and fix pushed out for this issue. I really like my phone and dont want to upgrade at this time.
Finally somewhere where people are actually having the same issue. I've tried factory resetting the phone, doing a fresh install of the OS (with firmware recovery tool) all with no avail. I note lose all my settings and app configurations every time the phone dies, shuts down or restarts. I hope there's a fix, otherwise it looks like a custom rom is the only way.
Has anyone tried wiping the dalvic cache? I can't get into the recovery on my phone so I can't try it, but heard I it might help.
Had the same issue last week
I was at about 20%, phone shut down. I plugged it in to charge, went to boot it up, and it got stuck on the Verizon bootup screen.
I waited a while and did a hard reset, and it came back on, but was completely wiped. So I had the same problem, which is a real pain, because I use the GOOD app for work, and each time that re-installs I have to get a new PIN. And I have had to re-install the app a few times in the past month for a variety of reasons...

I feel your pain. I use Mobilepass for work and every time my phone resets it deletes my token and I have to request a new one.....
Here is what I did two days ago that seems so far to be working for me. I calibrated the battery. I have tried this in the past but could never get the calibration to work properly. Each time I tried I had the phone plugged into the charger. This time I didnt and the phone went through the battery calibration process like it is supposed to.
Since I have done this my phone will stay on until it gets to 8 or 9% and then shut down but when i charge and turn back on all of my setting are still in place.
To calibrate the battery I held the up volume, down volume and power button (all 3) for a full 2 minutes without the phone being plugged in. During this time the phone will start and get to the HTC splash screen then shut back off, start again to the HTC splash screen then shut off, repeat, repeat, repeat.... after 2 minutes release the buttons and let the phone boot up, plug it in and let it charge to 100%.
I hope this helps,
This happened to me today. I let the battery get a little lower than usual last night, around 13% before shutting it down and plugging it in for the night. Turned it on this morning and it booted up normally. Didn't lose any apps or data, but every time I did something on the phone it gave me those little hints like its a brand new phone. I went to settings and it says it was factory reset at 6:46 a.m. this morning (about the time I turned it on).

Did it reset your ringtone and notification tone settings? Thats what it always has done to me.
I would just like to say that the same thing happens to me as well on my HTC one m8. Battery suddenly dies, now even at 25%, even after a calibration which is just a temporary solution, and when I turn the phone again, SwiftKey settings erased, everything went to stock, messages and contacts are preserved, but the apps start updating itself even though they are not allowed to and I have to manually set a lot of things. It is a total confusion and I literally can't believe HTC allows themselves to not issuing a fix for this disaster.
Was it cold?
Same issue. With mine it seems to be when it gets cold. I was skiing today in 20F but inside my pocket this really shouldn't be an issue. It has turned itself off and refused to restart several times when it has been used to take pictures in cool weather (I live in western OR, it doesn't get COLD, by cool I mean <35F but >20F, usually > 25F). This is the third time it has totally screwed up the phone when it has happened. On another occurrence it reset under normal conditions too. I'm getting pretty sick of it as it is quite a process to get all my VPN tokens reset, get all the apps back etc. Of course it waited until the warranty was out to start acting up.
This time is especially bad, the phone will not restart properly and important processes just constantly flag as stopping so that I can't even get past the initialization screen. It looks like I will have to do a full factory reset. If anyone from HTC is reading...Not acceptable and I won't be buying another phone from you.
Unfortunately I've reached the point where I wouldn't be surprised if it is a programmed planned obsolescence function, but whether or not, this is really annoying behavior.
Sorry to hash up an old thread but I put up with this crap for 5 months before I finally punched and broke the screen out of rage during an important business tech support call when I was at the clients location trying to service their security equipment, it was so embarrassing having to tell them I have to come back especially since it was a remote location.
Mine would wipe contacts, texts etc regularly. I ended up installing Super backup or something and saving my backups on google drive and just restoring everything everytime it happened.
I decided to fix up the phone and replace the battery, broken charging port and smashed screen and unlock bootloader and root but flashing superSU didnt work, got stuck in a bootloop. Anyways through all this I wiped all the caches (including Dalvik cache) flashed the correct stock rom and did the battery calibration and that seemed to have solved the random shutdown and memory leaking issue.....but I guess I wont know for a while.
I have a HTC One 610, and like every once in a while it well automatically reset it self whenever I am in the middle of a text message, on facebook, or even sending an email on phone. Its getting annoying when my cell reset its self.
what needs to be done to it? and should I do.

try a factory reset
I know its old but people are having the same issue still so I'm gonna paste this everywhere i find this problem.
There is a Modified stock rom named "Android_Revolution_HD-One_M8_53.1" and its almost the stock M8 without bloatware and so much more stability improvements. So hear me out and flash it with a custom recovery (i did it with twrp) and it seems to be working fine so far. Give it a go before you trash your -still so good- phone to the open seas.
Well, this issue is still happening. my phone has been doing the same for about a week now. ive made several attempts to reset the battery and had to reinstall back ups every time its happened also. the only difference i think now is that its happening at 90% instead of the usual 15%. ive been following instructions to hold volume up, down, and power (with the phone off) for about 2 minutes and then letting go. i have my extreme power saver set to come on at 15% but Im not even getting that low before it shuts off and resets. i have however noticed that recently that if you plug the phone on charge after it first dies you can avoid the phone resetting.. this may be a fluke but its allowing me to deal with the battery problem now without the loss of my data, contacts, etc.
This is exactly the reason why HTC One M8 is the last HTC phone I will ever purchase. Imagine the hassle of phone factory resetting on its own. Horrible.
Hi everyone, i know the title seems like it's just a trival matter, but trust me it's not.
The phone was bought new in August of last year (2015).
The story so far: I've been using sultanxda ROM for over 6 months without any issues, but i decided to test a different ROM, so i downloaded Darkobas rom and GAPPS, the ROM and Gapps installed fine but when i started the device and i was doing the initial configuration the phone rebooted by itself. It happened about 3/4 times and after that the phone had entered a bootloop. I tried to reflash the ROM and gapps, but the phone was restarting during the flash in TWRP. I decided to go stock Cyanogen OS, so i did a clean fastboot install of cyanogen OS. Everything went well the phone was working fine, but a few hours after installation the phone was randomly rebooting again, i decided i'll live with it and wait and see if it goes away by itself.
The phone was rebooting 2/3 times a day, during different acitivities so it was hard to pinpoint what might the issue be (even when locked in my pocket with all apps killed). After a few days of usage it just went straight to bootloop, after that i had issues to even install a rom (even via fastboot), because it would install everything fine and then it wouldn't start properly and would be in a bootloop (straight after installation).
I also tried the Bacon Root Toolkit installation as well as formatting everything and wiping everything. But even with the usage of Bacon Root Toolkit the random reboots happened.
So i installed an older TWRP recovery, i wiped everything re-formatted the phone to F2FS (was EXT 4 b4) and installed a F2FS compatible ROM (can't remember which one), after that installation everything seemed to work fine, but after a day or so the random reboots came back to haunt me again. So i reformatted the phone to EXT-4 again, installed stock cyanogenmod via fastboot (the 4.4.2 version), and updated it to 6.0.1 via OTA (during the course of a day or so, but even when the phone was on 4.4.2 i had a random reboot once), and the reboots returned ( i tried many different solutions, even the command line in TWRP "make_ext4fs /dev/block/mmcblk0p15"). I had NO IDEA what might be causing them but i thought that maybe the processor is ****ed and it's overheating, i returned to sultanxda rom (with the underclock to 1957 mHz).
After returning the phone booted correctly after a clean install via TWRP, but now it's rebooting again, and sometimes it happens 4/5 times in a ROW, sometimes it doesnt even reboot, but goes to black screen and I have to push the power button for 6 + seconds for it to reboot.
I've tried the stability test, or running antutu a few times in a row to verify if maybe it's the processor's/RAM's fault, but the phone didn't care, it rebooted randomly (sometimes 6/7 antutu runs in a row and nothing happened, sometimes rebooting in my pocket with all apps shut down). I've tried different launchers/messing with WiFi options/turning off the proximity check/turning off the trust agents nothing seems to make a difference. At this point I'm at a loss of what to do so i came here to ask for any advice. Is there any way to check if the phones internal memory is corrupted in some way ? I've tried searching for some apps but nothing turned out.

flash this solved my problem http://forum.xda-developers.com/oneplus-one/help/fix-brickloop-audio-fx-fc-efs-corrupt-t2879061
Flashed the persist.img the problem still occurs. 15 minutes after the flash the phone shutdown, black screen.
Your phone battery is dying...replace your phone battery and all the problem will go away....random reboot a couple of times and then goes straight to bootloop is a sign of a dying battery....trust me i know this cause it happen to me before and i'm sure you have the same problems....
this problems will get worst when you can only boot into your rom while your phone is connected to the charger and goes straight to bootloop when you disconnect the charger....

Shouldn't the battery meter go crazy after reboots or something ? Well i guess i'll try this, the battery is not a costly component. Are there perhaps any bigger batteries than the original one with bigger backs ?

Nope...the battery remains like normal but random reboot will happen more regularly until bootloop....
Not sure if there is a bigger battery but there is one thread here that show one battery with 3600mAh and don't buy OP2 battery as it is not compatible with OPO...

Ok thanks for the help, will report back with new battery.
Switched the battery, the random reboots still happen, decided to do a clean flash, after wiping the phone in TWRP during the flash of GAPPS the phone rebooted itself and is in a boot loop currently.
Ok so the reboots stopped, it was a battery issue, but now i have a problem with battery indicator it's stuck at 50 % all the time and the phone does not show when it's charging (no information, no LED color), but the battery is being charged because when i shut it down and connect the charge and battery level (which shows when the phone is off) increases.
I've tried to use it untill it shuts down then i charged it while it was off for 6 hours, but after turning it on it still showed 50 %. I've also deleted the batterystats.bin using TWRP but it still did not help. Any ideas how to make it show the correct % ?

told you it was a battery issues but look like you have another battery issues here...try disconnect the battery from the motherboard for 1 minutes before connect it again and do offline charge for atleast 30 minutes....after 30 minutes reboot the phone and look at the battery percentages...if its goes above 50% then you have solved your problems....if it doesn't then you might bought a bad battery....you need to contact the seller that sell you the battery and asked for replacement....
Well unfortunately after changing the battery for a second one (the random reboots started again on the new one) the issue still prevails, so i'm currently writing a ticket to oneplus in hopes of some help.
Thank you iPusak Gaoq™

You Sir iPusak Gaoq™ are amazing. I 've searched for 2 whole weeks and no one was able to zero in on the issue.
After reading your post, I changed my battery. 3 days back. Till now my phone is as good as new.
I cannot thank you enough. I tried everything from recovery to rom to stock.
Thank you Thank you thank you.
What peace of mind now !!!!!!!
You can try this it solved my problem without changing battery :-

For about 5 months my phone will randomly restart. It doesn't seem to have any rhyme or reason as to what app I'm using when it does it. It started just once in a while, then a few times a week, to every day and then multiple times a day. About 3 months ago I cleared the cache as my first "fix." Didn't work. About 1.5 months ago, I hard reset my phone, but restored my settings. I thought that worked, but less than a week later, the rebooting started again. So then last Thurs, I hard reset and did NOT restore any settings and basically set my phone up from scratch. the next day, my phone reboot, and every day since and today when I woke up my phone on the charger was off and wouldn't turn on (with 100% battery on the screen) until I essentially "soft reset" it. It has since rebooted 2 more times today.
I have a lot of apps on my phone, many that aren't used regularly. Booting into safe mode is the last suggestion ATT had but how in the hell do I figure out what is causing the problem??? Also, has anyone else had this issue and waht was the reason and solution?
