Help! Bootlooping out of the blue for NO reason - Essential Phone Questions & Answers

So... For no explainable reason my phone has gone into a bootloop, simply from me attempting to restart the phone.
Details of anything I can think of that might be related are below. I need a genius to help me A) figure out WHY this happend, B) help me figure out if there is a way to (non-destructively) get out of this bootloop (i.e. NOT having to do a factory reset), and / or C) tell me if there is a way that I can perform a full system backup using ADB, Fastboot or Odin with a phone that can't get past recovery or bootloader without going into an endless bootloop. I'm not a lazy guy and normally take the time to research problems and figure them out on my own, however at present this is my only activated phone, it's almost 11pm, I have to be up and out the door at 6am tomorrow, I will be judging competitions all day and will not have any opportunity to do anything about this until late tomorrow... In the meantime, I need a functioning PH1!!
My PH1 is the Sprint variant and I have not rooted it nor have I unlocked the bootloader. The only thing I have "done" to the phone is to sideload the latest OTA, NMJ32F (the day it came out, over a week ago, and it's functioned perfectly since that update). My phone has been in use throughout the day today with no difficulties. I went into a building with very spotty service for several hours this evening. On the way home, I noticed that I was stuck in 3G service, despite being in an area I know has good 4G/LTE coverage. I also noticed an unidentified icon on the status bar, a rectangle, which was located (I believe) to the right of the battery icon. It looked like a rectangle, perhaps representing a screen, or a phone? IDK. The other item of note is that I did sign into the guest account on my phone so that my daughter could use the stopwatch for timing competetion events without tampering with anything. She didn't drop it or get it wet or anything along those lines... she used it to time events, returned it to me in perfect shape. I logged out of the guest account, back into my account, rebooted to try to get the phone back into 4G service, and boom, I'm stuck in a frigging bootloop for no apparent reason.... And I'm about to lose my mind over this.
I CAN get into download mode and into recovery mode by holding the appropriate button combinations when it loops, but from there whether I power off and power on again or whether I select reboot from recovery menu, it continues to loop...

Well folks, still strange, still unexplained, but I had to bite the bullet and factory reset, just can't afford to wait. I'm still open to any thoughts on what might have gone wrong though I suspect we'll never know. This phone has been a bit buggy from day 1, things like BT randomly shutting off, VoLTE wouldn't stay enabled, etc... Hopefully this is the last time this happens. Still love the phone though!

So I am running O beta rooted and last night this happened to me. I ended up going into fastboot and starting OS through there and I had no issue with the reboot bootloop. However, last night I went to bed with a phone @ 75-80% and woke up 6 hours later with a dead phone. Charged and rebooted this morn and everything seemed normal today. It was super wierd

Had to return mine for this very reason. Less than a week in service and went into boot loop. The reboot happened after it lost all battery power (corrupt filesystem?). Several factory resets did nothing to fix it. Removed the SIM. The phone was also fully charged. Did not try ADB as it was brand new and a return was the safest easiest option.

Any issues since factory resetting? I'm having the same issue. Not sure if i should just return the phone or not.

I am stuck with the same problem, and this is my second phone already. This one doesn't stay on long enough even for an attempt to factory reset. I will send it back again, but I have no hope. Time to cut my losses and move on. Going to Pixel. And I sooo wanted Essential to succeed!

interesting.
If it's your second phone, have you looked at what applications you install?
The probability of getting two bad phones is pretty slim unless there is a major manufacturing flaw.
Not saying it can't happen, but it would be unusual.

Could it be due to Encrypted Data partition?
It once happened to me on a Huawei Mate 2 which I encrypted data and battery dead, then bootloop.
If that's due to corrupt encrypted partition, there seems only other recovery mode can help you get some files back.

Phone won't stop vibrating...

Posting here to see if more exposure would help.
Was wondering if anyone has run into this problem?
The phone was fine, rooted and everything, for a month give or take. Then all of a sudden, today, it started acting weird.
It was fine in the morning and everything, was able to use wifi, check emails, and stuff.
Then BAM, I tried to make a call, it didn't go through for the first 20 seconds or so. Then connected and a message kept popping up saying Phone is stopped or something during and after the call.
So, I restarted the phone. It restarted fine and everything, got past the 2 Samsung screens. Then hit the T-Mobile screen. and has been stuck on the T-Mobile screen for ~30 minutes now and just keeps vibrating.
It's getting quite hot, both front and back.
Any advice? Stupid Samsung making this a closed system so can't pull out the battery.
Can't even turn the phone off, only able to get to Download screen.
Weird problem.
Is there any way to pull the data and stuff off the phone at this point?
I'm thinking of going the factory reset route and do that to see what happens and see if it will fix the problem. It would probably not retain root am I correct and I would have to re-root again?
I could get into download mode and recovery fine.
I have had this issue on both at&t and t-mobile firmwares, but only while rooted.
Best thing to do is to re-flash the stock firmware again(or go to a different firmware if you'd like) but this is the reason I'm currently avoiding root. It soft bricks about a month in and is an easy fix but its annoying.
Was wondering about that too (flashing the stock firmware). But, will it wipe everything I had on there? Will any of my txt msg's and photo's or summat be lost to the ether?
Stupid question, I know, but had to be asked.
Thinking about flashing stock firmware and rooting agin for the sake of being able to do it again lol.
Well, if you flash stock, it does factory reset. That's why I have backups lol all I have to do is log into my Google account and everything is there.

Did you have security log or security update disabled as that updates and causes weird after affects.

These two threads describe exactly your issue and solution - http://forum.xda-developers.com/verizon-s7-edge/help/g930t-updates-unroots-overnight-t3426636 and http://forum.xda-developers.com/tmobile-s7-edge/help/rooted-weeks-rebooted-stuck-t-mobile-t3425814
I had the same problem, twice I had a rooted device totally lock up and had to re-do everything. But after disabling the security updates as advised, I'm currently going on two months without a problem.
Hope this helps!

Galaxy Note 4 constant freezing & restarting!

Hi there,
So my galaxy note 4 is having some serious problems for the last couple of days and it's really starting to bother me. I've tried doing everything I can find online so far but to no avail I've had no luck at all. Basically, my phone constantly keeps freezing and restarting. It will crash for quite a period of time then restart itself, crash and restart. It probably crashes and freezes about 80-90 times a day? More if I'm trying to use it of course (It also resets itself when not using it).
I've tried everything, bought a replacement (genuine) battery and not fixed it. Got to the point where I seen online about doing a factory reset so I backed everything up to my computer, started the factory reset and when I was going through the setup of logging into google and samsung account, it continues to crash and freeze all over again. (It crashed & restarted whilst retrieving my apps from google, thus I had to reinstall my apps again manually after I finally got it setup again).
To make matters worse, I cancelled the insurance cover last month and only a few days ago this started happening. I've not dropped the phone or damaged it in anyway, screen is completely perfect too. It just constantly crashes and restarts on it's own. Get a phone call and it crashes, using google maps, crash. It's beyond unusable now. I still have 4 months left of the contract before I'm due an upgrade and I really don't think it will last me that long.
Can someone PLEASE help? Suggestions would be so helpful!!!
Thank you!
P.S Phone isn't rooted, only using Nova Launcher prime.
Sounds like your battery is on its way out. Have you tried a new battery?

Earlier in the week I had an error I've not seen before. Phone restarted and went to black screen sort of looking at a recovery screen with android logo and in the centre of the screen was the message
"Kernal Panic" with some information on the top. This only has happened the one time and hasn't happened since. Took the battery out and restarted again...

How do I go about doing either of these....
Still happening and it's driving me insane, It won't last me until the end of my contract (January)
Its rebooting 80-90 times in ONE day? Good god! Have the phone turned off then. Unnecessary pressure is being put on the phone mate!
Factory Reset isn't going to solve it anyway, its for tiny problems. Your system is somehow messed up badly.
Do what the above member said. Flash a stock ROM via Odin. But before that you need to completely wipe the phone. To completely wipe you need a custom recovery like TWRP. So flash it now, root the phone, then reboot into TWRP and use the Advanced Wipe section to wipe everything (external SD not needed), then reboot the phone in Download mode, and flash the latest stock ROM via Odin.
You are now part of a large group of us having the same issues. Several things have been tried. One thought is that the motherboard is faulty. Replacing it would be expensive. Download the app "wake lock" and set it to partial_wake_lock. Don't ask me why it works, but it does. Apparently the phone goes nuts when the screen tries to go off, the partial lock keeps it from crashing. That makes the phone usable, hopefully a permanent solution will become available. ;( The only time it goes nutty again is if the battery runs down and when I restart, the app is not running. Going back to the back and setting it to partial has allowed me to play games, etc for extended periods of time and no problems. It shouldn't be that way, and I really suspect the marshmallow update and then security update screwed it up, it was fine before that.

Which version is your note 4? verizon? att? tmobile? sprint? etc united states variant? other country? This helps find out if others that are having the same problem are on the same setup as you and more importantly tells me if I'm likely to have a problem with mine getting ready to come. :laugh:

80-90 times in one day is probably being generous. I've not actually counted how many times it restarts but If I need to use my phone I can guarantee it will be restarting a couple of times. Driving using navigation *Crashes* Inbound phone call *Crashes* get text message *crashes* all followed by the phone restarting. Practically unusable.

I'm gonna give this a go and hopefully it'll help! Thanks for the advice. Funnily enough, for a couple of months the phone has been prevented from the screen going off. I get a text or a notification and the screen would stay on until I hit the power button to turn it back off. Get a text in the middle of the night and I'd wake up to a boiling hot phone the next day, almost too hot to even keep in the hands. This literally frustrated me beyond belief and had to get a new battery and all sorts of complications. Also you mention the android update which made me think, I NEVER had this issue before I installed the security update for 6.0.1 - I put my money on something really stupid that's sincerely knackered my phone for certain!
While upgrading a phone, especially for major upgrades like from LP to MM, OTA method should always be avoided. You MUST do a clean flash of the ROM, otherwise you are bound to have problems. 80% of time people complain because they didn't flash the ROM cleanly, so whatever you want to do now, do it, but if it doesn't solve it (very likely it won't), then kindly flash the ROM via Odin after a full wipe. And if even that doesn't solve it then its hardware.

Thanks for letting me know your version. Hopefully it wont affect mine since mine is US Verizon. But out of curiosity have you checked for even the slightest sticky button? I've had phones where a button started to get tacky and would cause it to keep the screen on or go on and off like what you're saying. May not even feel like a sticky button. Do they all click very responsive? or do any feel like they have a dull thud experience?

The volume rocker and power button feel really loose but this isn't really something new. Something I have noticed is when I take the cover off the back, the battery barely stays in itself. If holding screen upwards and battery cover off then It doesn't hold the battery which made me possibly think that perhaps the battery does not situate properly and doesn't deliver enough power (or too much) but this was just one of my theories into why the hell my phone is acting this way.
Edit:
Forgot to add I'm running the security patch 01/08/2016

Are you able to wedge a folded small piece of paper between the bottom edge of the battery and the phone to make the battery fit tighter? I mean it's not good to have a loose battery. But I can't see how that would cause the screen to stay on. If anything I would think it would cause the phone to shut off or reboot.

Let me know how it goes. There are other threads about same issue. Most of us have tried reflashing, wiping everything, custom roms, going back to stock, trying to downgrade, taking out the sim card, taking out the sd card, not having both in at same time, brand new battery, I think even putting the battery in the freezer momentarily, etc. etc. Nobody seems to have had any real luck with it, except those who were under warranty and got a new phone, or are capable and wiling to exchange some hardware. I just find it odd that it happened all of a sudden after updates and recently to many people.. Still, I keep coming here hoping someone will have great news. Mine started with marshmallow, but definitely got worse with the security update.

Aside from the previously proposed wake lock solution, members in the T-Mobile Note 4 threads have experienced limited success with a downgrade to LP from MM.
From my reading, these issues seem to be common across all Snapdragon models, not to say it Exynos is excluded (I don't frequent Exynos threads).

I tried that and it didn't work for me. The only surefire solution is a replacement device, but even then there's no guarantee the device won't start acting up in the future.

this is the issue I'm getting...I did a complete data wipe using twrp...now stuck on this screen...cant even push files...device not recognized in adb or fastboot mode....
what to do...??

Well a new motherboard was the only thing that fixed it for me, replaced under the 2 year warranty but I had to wait a while for parts. What is interesting is that the phone is much faster, the battery life much better than when it was new. Also it now barely gets warm using google maps - before it got quite hot. It would be very interesting to find out what percentage of Note 4's have been going down with is problem - mine was a fairly early one - was Samsung rushing to beat Apple two years ago and a bad batch of parts used? I don't know -we need some answers on what is the problem to be sure.
Just a personal experience and thus advice, please don't keep flashing bunch of stuffs every other day. The more your eMMC gets used more chance of your phone getting messed up. This is how my Note 3 died, kept flashing this and that, and did the same on Note 4 too, but have now stopped. I don't know whether there's an endurance rating on these eMMCs used or not but this is what I think, I could be wrong, please quote me in that case.

Wow, that sounds promising. I'm sending mine for replacement, and although I'm not getting a new MB installed, hopefully the incoming unit will be similar in performance to yours.

Your reasoning sounds plausible, but my phone suffered similar issues and I only flashed my unit 2-3 times in the 14 months I had it.

Galaxy S5 Reboot loop

Hi all,
My galaxy s5 is stuck in a reboot loop. It started doing this today around 12:18pm and I can't get it to stay on long enough to back up my data. I took it to AT&T and they basically did nothing but tried a different battery and booted into safe mode. Neither of those options worked. I took it to best buy and the tech installed the latest updated and flashed the ROM (I believe). Still didnt work. She believed the issue was with the battery but didnt have any new ones there to test so I went to batteries plus and tested a brand new battery, still is rebooting. I am home now and just wiped the cache in recovery mode, still not working. Is there anyway at all I can get this phone to turn on long enough to backup my data? Any other commands I can try to clear whatever is causing this? I was not using my phone when this happened. It died at 15% which I didnt make too big a deal of because I know the battery has been weakening, but when I charged it up for a bit then turned it on, this problem started. When I turned it on, I had a text message coming through and then it restarted. As I was able to get it on for a bit that same text kept coming in over and over again so I thought maybe something with the messaging app and I disabled that all together but the problem remains. I hope someone can help me out here. Thank you.
SOLVED: Samsung Galaxy S5 Reboot Loop
I figured out a workaround and I take full credit because this creative solution was no where to be found on the internet nor did AT&T, Samsung or Best Buy offer any other alternatives aside from wiping the device. This is what I did:
I booted back into Recovery mode and looked through the logs for any indication of what was happening. My assumption was that it was a driver error and so scrolling through the logs I saw an error that said something like fail psy battery. I immediately think maybe its the drivers for power so I thought I'd see how it would respond if I put it in Ultra Power save mode. Thankfully the phone stayed on just long enough for me to put it ultra power save which did work. The phone stopped the reboot cycle it was stuck in but I still was not able to back anything up since the Ultra power save disabled the USB drivers and port. I let it charge up overnight in ultra power save and said I would try regular power save mode in the morning to see if that would also work but this time allow me mass storage access. Well, that worked! I put it in power save and I am backing everything up now as I type. I've got all my pics and now just letting samsung switch do its thing to perform full backup. YAY! I WIN! Hopefully this helps someone else that may have this problem and have tried everything else that is recommended for solving this issue.

Don't really get it, what cause the boot loop in the first place? And you are flashing back to which rom?
I don't know what caused. I wasn't using the phone when it started. I hadn't downloaded any new apps and I wasn't messing around with the OS or system files. The phone battery died at 15%. I plugged in the charger and disconnected when it was at about 28%. I powered the phone on and there were a number of text messages coming through from my friend I was going to lunch with. I opened that message and noticed the text was duplicating itself then it rebooted. Each time I powered it up and got in for a bit that same text was coming through or trying to over and over again. So, I don't know what caused it but I have all of my data backed up and I am going to wipe it now.
Also, the Best Buy tech flashed the ROM so I am not sure which version or anything like that.

Moto Z Force - Restart Loop

I'm having this issue on my 2 week old Moto Z Force.
I actually noticed a similar issue on a display model in Verizon but chalked it up to just that.. a display model in Verizon and I carried on with my purchase.
I've had a few experiences where it randomly reboots and then it's good to go again. Seems to happen more frequently when the phone is in high use, so I suspected an issue with RAM being full? The restart seems to take place at the same part of the startup animation every time.
TODAY - phone was in pocket while I was on a call for work and I felt it vibrate on a consistent interval. When off the phone, I looked at the phone and it is in a restart loop. The only thing I can do at this point is hold the Volume Down key to get into BIOs (through the rebooting loop) and then I have the following uptions:
1) Start
2) Restart Boot loader
3) Recovery Mode
4) Power Off
5) Factory Mode
6) Barcodes
7) BP Tools
8) QCOM
9) Bootloader Logs
If I sit in this menu inactive for awhile it will timeout and just shut the phone off until I turn it back on and then the loop resumes. I'm beginning to think I need to go with option 5 here... any help is appreciated...
No new apps were recently installed. I barely used my phone the morning when getting to work besides charging it to 90+/- % on my way in.
First I buy a hand grenade of a phone, forced to return, and now I buy a phone that is actually showing me a big issue (it is getting hot too). I'm going to let it sit off before trying a Factory Mode. :crying:

Thanks Steve. Any suggestion on where would be best? I would have thought the Q&A would be accurate...
I have had this phone for just over two month and have not had any similar issues. I assume that you've already tried options 1, 2, and and 4. Have you also gone into recovery to see if you can clear the cache?
I would personally return it as broken, but I save everything important to my SD, just in case this kind of thing happens.
I had this very same issue. I did a hardware replacement with Verizon and the new phone works great.

Awesome! Glad to hear that it worked out for you. Fingers crossed they don't give me a refurbished model (again, mine was 2 weeks old) and that I have the same luck as you.

I have tried all of the options at this point and none of those work. I can't even get into recovery. Every option does the same thing... reboots, reboots, reboots, etc.
New phone should be here tomorrow. I've got the good old run around on this one though and I'm not happy about it with Verizon and Best Buy. Best Buy's return policy is 14 days and I ran into issues on day 16, no exceptions according to them and off to Verizon I go where I had to purchase a temporary flip phone for the week my phone has been out of commission.
I'm in need of a new SD card before I put anything on there, it has been flaky. The only thing I care about on my phone is the media (photos, videos, and music), all of which are on Google. The crap thing is that now I need to spend another X hours putting all my apps, passwords, etc. on it to my liking. Just did this when moving to the Note 7, then Moto Z Force, and now again with the replacement. Starting to get annoyed.
Update - when switching to the replacement device I found the issue followed to the new phone... Meaning the issue was with the SD card or the SIM card. Found it was an issue with the SD card after switching between the two phones and experimenting. Unreal. Who would have thought?!
I will be formatting the card and keeping this thread posted on if that resolves it or if it's time for a new card (as I mentioned above).
I am very hopeful with your post. My phone has been going crazy with the rebooting mode for two days now. I brought it into Verizon yesterday but all of a sudden (of course) it started working. Now today its gone back to rebooting, over and over and over again. 2nd day in a row I am going to waste my lunch hour and run to Verizon. This time I will ask them about a new SIM card. BTW... I just got a new (refurbished) less then a week ago.

I just fixed my Moto Z Play by removing the SD card... for the second time... -_- I've had a previous issue where my phone rebooted as part of an update and it stopped seeing my previous SD card. After checking the SD card in various other systems, I found the SD card was completely shot. After some digging online, there is apparently an issue with the new Moto Z's that if your SD card isn't fast enough (somewhere around 85-90+ Mb/s)m, the Moto Z will slowly start to eat your SD card until it fails and causes issues for your phone. In this case, my second SD card failure was that my phone went into infinite booting loops until I removed the card. -_-
This card lasted longer, mainly I think due to the fact that it was larger and faster then my previous one, but it looks like I will need to get a new fast card.
Anyways, I hope this helps you or anyone else who comes across this thread.
About 2-3 weeks ago, the same thing started to happen to me, after that, phone started to act crazy...
-Bluetooth connection was working but glitching,
-Overheat (bottom of the phone) then started reboot in loop (until at start I'm able to turn off wifi). Did everything your supposed to do, clear cache, forget network, deleted my latest app, reboot, reboot in safe mode, remove sd/sim tray... the issues we're still there...
-After a few days of repeating all those steps (or don't know what I did), I finally got rid of the oveheat reboot loop when the wifi is on. But can only see and connect to 2,4g network, no 5g (doesn't see any) and no Bluetooth (turns on, but doesn't see anything), every other device in house works and connect like they should.
-the setting app, and the phone app started to be slow (freezes for a few seconds before the system ask you if you wanna wait or close the app, I choose wait and the app unfreeze)
-Ive tried the rsa (repair system assistant) from verizon without any fix
-finally decide to go for the factory reset. It fixed the freezing issues, works like a charm, but still no 5g wifi nor Bluetooth...
Is there a driver update possible for this ? Or because of overheat it might have damage the device...
I have the phone since September, never had any issues, went through all update, force droid edition xt1650-02, build ncl25.86-11.5, nougat 7.0 (wish verizon would update to 7.1.1 anytime soon), since its gsm unlocked, I'm using it on a Canadian network (Fido)
thanks for this thread. It was able to help me diagnose my wifes phone. The SD card she has been using since her DROID CHARGE (2011!!!) finally bit the dust in this phone. I swapped it out for a new Sandisk micro sdxc uhs-I up to 80 MB/s card class 10 and it booted. funny thing was she was not even storing pictures on the card.

I've had bootloops happen a couple of times for different triggers, and I still run the phone stock since release date with no updates ever taken. This has worked to correct the issue for me a couple of times. Give it a try:
Let your phone get down below 5% battery life, then plug into the turbo charger. Then fool around with whatever triggers the reboots.
Eventually the phone will not restart because the phone's battery needs to charge a little. When phone charges beyond 10% try to turn the phone back on, and see if boot loop persists. If it persists drain below the 5% battery life and try again. Usually, when I have fooled around with this scenario two or three times the bootloop has corrected itself.
Hope this works for you. Good luck.
Thanku, I will definitle give it a try .... and i am updated to nougat all updates till date installed...
Still restarts.... its been a month... without solution..

A couple of weeks ago, the restart loop happened to me again, and my usual tinkering while connecting and disconnecting Turbo Charger wouldn't work. So I did some research on "stuck power button" or "power button not working".
I did the following:
I blew with my mouth over the power button (kind of like puting your lips in position to whistle)
I also gently tried to clasp the power button using a pair of tweezers, but couldn't. Instead I just kind of lifted/tugged-on the power button from the top and bottom.
I feel like I didn't really do anything, but the phone has been working for over a week now. Maybe pure luck.
Its weird, this made me think it is a hardware issue, but somehow the phone reacts as if it were software related.
Give it a try. Hope you have some luck.

Strange instances of multiple reboots!

This is really starting to get on my nerves now. Ever since I got my new S10+ from AT&T, it's occasionally done this thing where after I reboot the phone, I unlock it, and it briefly says "starting phone" on the home screen, and then will mysteriously do a quick reset, where it skips the AT&T logo and jingle, and just shows the Samsung splash screen , then takes me back to the lockscreen and it's usually fine after that.
However, Just now I decided to reset my phone, like one should do periodically, and it did the strange double reset after unlocking... Then when I unlocked it, after the "starting phone" message I tried to open a browser, and BAM! Quick reset again! Unlocked, let it start up, tried to open an app, BAM quick reset again after the screen briefly shifted from landscape to portrait mode (even though I was still holding it long ways in landscape position). Its never done this before and I'm getting concerned. It's never randomly reset while using the phone, this only happens right after a reset.
Any ideas? I've already tried wiping partition cache after big updates, doing soft resets. I'm worried that I'm going to have to end up resorting to a factory wipe, as others suggested I do when I was having battery drain issues on the ASD3 firmware, possibly because of restoring everything from a backup of my last phone when I got this one. Because supposedly restoring from backups from AT&T, Google or Samsung has caused all sorts of problems for people. I really don't want go wipe everything and spend hours try to get it all back on here manually if i don't have to.

Had an issue with this early on but seems to have been fixed at some point, I'm I'm exynos though so probably not much help!

Dang... So it does appear to be an issue experienced on both Exynos and Snapdragon variants. I wonder if there is or will be a fix for this. I've been asking around and haven't gotten many responses about this problem at all. I'm concerned because it seems to be getting worse than when I first got the phone.
I'm having the exact same problem. Sometimes it goes through quick reset, full reset, a couple more quick, then back to the Verizon logo, then starts up. Opening an app at that point usually does another quick, then full, then everything works. Glad I'm not the only one, but I haven't found any solutions either.

Mine does the same. Unlocked bought directly from Samsung. I don't reboot the phone very often so it doesn't bother me that much.
