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.
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 guys,
I have my new phone bought on ebay (I forget the exact seller because was a friend of mine who bought it, i am overseas in Cuba) and from the beginning some icons are not painted correctly.
The thing has gotten worse since the phone restarts for no apparent reason and no matter what I am doing. Originally it came with the ZV8 software version , but i have permanently the notification for a downloaded update to install. So i do it and now i am with ZV9 version and has maintained the same problems.
I need any help you can give because i can't return the phone to US and here there is no official warranty service from LG that i can use.
Thank you and best regards.
I had a similar problem with my G Flex 2 after it updated to 5.11. It would randomly reboot and restart with optimizing apps almost every time. It did this at least twice a day. It would also have issues installing apps sometimes saying there was no storage available. When it did install apps sometimes they would crash when opening them. Eventually after resetting and erasing my device four times the issue went away. I read that sometimes this can be caused by a bad battery. See if your device stops crashing when it's plugged in. If it does it's probably the battery. If not try resetting it a few times in a row and see if the problem is still there.

Hi probaina, thanks for your answer!
By chance yesterday analyzing what happens I thought it could be a battery problem, because when reboots occurs and I watch the battery use log sometimes I find out that the percentage of battery drops for no reason. For that reason yesterday I left the battery ran out completely and then pluggin the phone on charge overnight in the hope that this would solve the problem. But today it has restarted twice already. I'll try what you say to keep the phone plugged in to see whether the problem occurs and I will keep you updated. Once again thank you for your time and response.
Best regards!
PS: Sorry about my english, is a work in progress!
I have seen this problem online with the Edge, but no solutions other than changing the device out. Hoping someone can tell me whats going on here.
I bought this phone from Sprint on 10/7/16 and didn't have any issues until 11/7/16 (1 day out of the time for me to add insurance to get it replaced).
On to the issue. It restarts every 2 min, if I allow the screen to turn off. If plugged in and charging, it just shuts down and freezes. Have to do a soft reset to get it up and running. I have no to date done 4 factory resets, and didn't install any new apps and pulled out my Micro SD card as well. All the pre-installed apps are up to date, as well as my firmware, profile, hell even my prl is up to date. Still happening.
I have been able to stop it by turning in the "Always on Display" that shows the date, time and battery percentage. It seems to have stopped the problem, but lets face it, that's not a fix. Its a bandaid over a leaky pipe.
Anyone have any suggestions? I have called Samsung and they said I can send it in, but I don't have a backup device at the moment. I sold my Note 3 when I bought this phone. I know I can get a loaner phone from Sprint, but I don't want to pay for it.
Thanks in advance.
PS - Non rooted phone.
My Nexus 6P was recently broken but my GF (on accident lol but still she's lucky I love her. If it had been anyone else, like one of my guy friends, I prolly woulda had to hit em haha j/k)
Anyways, borrowed a friend Acatel 4060a IDEAL. He dropped it off last night. I then factory reset it and all that, hooked up my google accounts, downloaded WoW - Hearthstone and my Drastic DS emulator, and everything was fine. Then this morning I was bored and figured I would see about if this cheap POS is rootable. Which it is, and I proceeded to do so. Everything worked fine the whole morning, til bout 45min ago, I was leaving to run up to the AT&T store to get a SIM card so I could hook it up to my account, and on the way out the door I reset it cause I just had finished updating some apps in the play store. It then became stuck at the Bootlogo. So I then did what you always do in this case, try taking the battery out and the SD Card, then putting just the battery back in, see if that works. Didn't. Tried just resetting it a few more times, and let it sit for like 20min hoping maybe it was just taking extra long. Nope. So I then booted into the stock recovery wiped the cache and did a wipe/factory reset. Still nothing, still stuck. Tried a couple more times. Still nothing. And this phone apparently doesn't have a download mode, so I can even plug it into my laptop cause it can't make a connection obviously without being in download mode, or fully booted into the OS. I am at my wits end.
I'm hoping one of you fine peeps might have a suggestion of something I could try that I perhaps have overlooked or didn't know about. Learn something new every day right So please HELP ! lol its gonna be at almost 2 more weeks til I get paid and will be able to afford the Insurance Deposit for them to send me a replacement Nexus 6P, and I got way too much going on right now and I can't go two weeks without a phone.
I'm All Ears !

I'm assuming you used Kingroot to root it? It's a common issue for Kingroot to cause a bootloop.
Typically, this is fixed by re-flashing the stock firmware but you have to get it to connect to PC to do it, and that's only if the stock firmware is even available.
