Hey all.
Been having problems with a Nexus One that crashes at seemingly random times.
I have been unable to pin it on anything, and am asking your help.
It appears to be independent of the Rom installed, whether there is an SD card present, or whether its connected to a USB cable or phone charger.
Any help would be greatly appreciated.
Phone Info:
Nexus One (AT&T model)
Radio: 4.06.00.12_7
Current Rom: Enomther's TheOfficial Nexus1 - v2.12.2
Provider: Rogers (BC, Canada)
Logcat output attached as screen capture image.
This has been reported by a few users. I sent mine in for repair and got it back not repaired - they couldn't replicate the problem.
My case has been escalated which means a HTC guy called and asked me a few questions and then told me to wait for an email (a few days ago).
I believe my problem started when I seriously overheated it ... driving with navigation on, 3g downloading maps and traffic data, car charger plugged in all on a very hot day on a very hot dashboard. This was the first reboot and they got more and more often after that. Now I can't run anything for more than 5 minutes if 3G or wireless is on (in 'Airplane' mode I can run for quite a while without a reboot).
mine was doing the same thing.
getting progressively worse until the phone was basically unusable earlier this week.
I was running CM6 at first when it started happening.
installed the newest nightly and it worked better for a bit then got even worse.
uninstalled the stand alone version of gmail from the market and it worked for a couple hours and then kept rebooting on me.
finally i did a factory data/cache wipe and installed a rooted stock rom and things have been working PERFECT for over half a week.
I had the same issue. first reboot happen when i had nav running plunged in then after a few months utube , browser etc would restart my phone. it didn't matter which rom i used or stock. I sent it in and they fixed it. i had issues with htc but it got fixed.
Yup, same here, strange thing is it isn't a complete reboot. Hard to explain but what happens is i'll touch the phone and then it will immediatly go to the CM6 boot logo, then immediatly to the lock screen, (which I have disabled) then to my normal desktop. Total time elapsed maybe 5/6 seconds, wierd.
A normal reboot usually takes about say a minute or so. just started happening 3/4 days ago, and happens maybe twice a day at most, some days not at all. Probably wait until Cyanogen includes 2.2.1 into 6.0.0 stable then reflash.
Ive been having the same problem for about a week now, but I'm still using stock, not rooted. Its weird, because its a really fast reboot. It goes to the Booting X, for about 6 seconds, then it boot up just fine. I cant understand it.
this really sucks
I am keeping my ATT nexus one around for gingerbread but these random reboots are really killing me....I use the phone for five minutes and it just reboots by itself....The phone runs really well for those five minutes...Ive done five factory resets but it is still just doing these phantom reboots.... Anybody find out anything more about this...or know a fix....the phone is not rooted and it is clean stock froyo...so please help or keep talking about it so htc will address this issue lol which i doubt since this phone is starting to become ancient....(cant wait till nexus S) =P
With regards to the original problem posted, I believe I've managed to diagnose it correctly.
The problem lies with faulty heat distribution. The phone would crash and reboot more often in times of great stress:
charging the phone (heats up the battery)
running many applications at once (heavy system load)
navigation (heavy dataand gps traffic, image processing)
This coupled with the fact that changing the OS did nothing to remedy the problem solidified the notion that the problem was hardware based.
Given this, I contacted HTC Nexus One support and had the phone repaired.
Note: HTC will honor the warranty and fix hardware issues for an unlocked Nexus One. With software issues, you're on your own (for obvious reasons).
This is exactly what my phone is off to warranty for. I experienced this with every rom tried. I wipe my phone completely and put stock froyo on only to see the exact same behaviour...so at least I'm not crazy
The tech told me it was a hardware problem so that is a bit of a mind ease.
It seems Nexus One and Desire are really similar: HTC Desire rebooting on its own.
P.S. It's a problem with faulty motherboard, if you're within warranty, it should be replaced.
I also have been pleasantly experiencing this issue with the nexus one, so i sent it for repair at HTC and they have said it is an issue with the motherboard and it has been replaced, it is now in the post so I will update this post when I receive it to whether the problem is resolved. Hope so was driving me crazy!
The log did not capture the error. In most cases its a software issue, not hardware. (has happened to me too, not recently though)
Well an update as promised.
I received my N1 back after UPS had finished not dispatching it due to "Adverse weather conditions" and the issue is GONE!!! I know a week isn't really a long time to trial the device but this was happening several times a day.
HTC replaced the motherboard.
My advice to anyone having this problem, is to send it to HTC for repair (dont be worried about it being rooted/custom ROM etc mine was and because its a known hardware issue they really aren't bothered about it.)
It took two trips to HTC for them to finally address the issue. They did fix something (they didn't say what) and the problem is gone.
I believe it was the motherboard because Swype Beta decided that it was a new phone and not the one I registered (so it would not install).
The ICS update finally appeared in France for stock Note.
It appears the update was pulled shortly after because a lot of users bricked their Notes in the process.
Moral of the story: don't update as soon as you see an update, but wait...
Samsung really sucks at software development.

as tu une source s'il te plait merci
Samsung france facebook page for the source.
SFR update and XEF for the short time i spent there.
i'm in the same case except that i'm booted and running( for me was a FOTA update, wich installed nicely except with a "failed " message after the fist boot), but the phone cannot be mounted by any ways under windows now ( even with drivers reinstalled ).
But some seems to be blocked in bootloop
Epic fail on this one, especially just before a week-end.
I'm one of the lucky few that got it to boot - sigh come on Samsung!
Managed to upgrade to ICS with 'failed to upgrade firmware' warning.
Missing S Note application, not sure whatelse it might be missing.
You can manually install S Note app by looking up apk file.
Search 'S Note app xda' from google if anyone having similar problem.
Kies 2.0 is recognizing phone as well. I can link screenshot if anyone need for w/e reason if it may help them.
Also, battery drainage problem still there i believe.
Tried the infamous aeroplane mode method, not so sure if it helped:
1. Turn off touch sound and screen lock sound from setting->setting
2. Turn on aeroplane mode
3. Switch off phone
4. Take out battery for 10sec
5. Boot and wait till everything loads
6. Turn off aeroplane mode
App called 'Play Movies' was installed along with ICS, but it gives 404 connection error for 'movie rental' section.
Other than that, Note is running really smooth with ICS.
Firmware version shows up as PDA:LQ3 / PHONE:LPT / CSC:LP1 (XEF)
Wasted time trying to download this so-called update

When I see that, I'm happy to install safe custom roms...
It's a shame for such a company to provide such crappy roms...
Well I am one of those who got stuck on the infamous Samsung logo...
Stock Note, purchased in November, never rooted, 2 GB updates via OTA since November, CSC XEF.
Yesterday morning I got the upgrade notice, did it OTA and on rebooting stuck on Samsung screen...
As an idiot I had been waiting for the "official" ICS ROM.
Thanks Samsung, lesson learned.
Many phone manufacturers will tell you to stay away from custom roms to avoid bricking your phone but to brick your device when updating on an OFFICIAL stock rom after receiving a notification is definitely UNBELIEVABLE !!!!! What is Samsung doing to this expensive device - after the EMMC Bug episode where many people have bricked their Note, now we have another update problem!
Samsung's reputation will take a hard punch with these things if the press writes about this. I think most people who bricked their Note will be fed up and avoid Samsung's phones in the futur.....

totally agree... it would have been good for them if they silently provide fix for the emmc bug... staying on GB has become the best solution to all this crap..
I have to say that I'm glad to hear of this. At least it's not just me!!!
My French note got the update yesterday and although it's not hung up or bricked, it certainly has huge issues. Running so hot and battery discharging even when connected to PC by usb. Using wall charger is barely keeping up with the drain even when not using phone.
Have done battery pull and cache wipe twice. No change. Factory reset, nothing either.
Swype not working. Premium suite totally missing. Really disappointing.
Probably not worth waiting for them to figure it out. Downloading UK version now.
I left my note on overnight under the following condition.
Wifi off
Bluetooth off
Data off
Auto rotation off
Gps off
Silent mode on
Power saving off
Between 1am and 10am battery % changed from 81% to 79%.
Quite satisfied with standby drainage.
I just did aeroplane methid as i mentioned on page 1.
Not using any battery save apps.
However when using apps such as dolphin browser, s note, s memo, there seem to be heavy battery drainage issue.
Charged fully then used the browser for approx. 30min and it was on 90%.
Hey guys..
I've owned all the Samsung Galaxy phones from the S+ right up to the S4 and I've flashed firmwares over all of them with generally no problems at all.
But lately I have a constant issue that has been plaguing my Galaxy S 4 (i9505) phone since I flashed the 4.3 i9505G (GE Edition) ROM over my phone.. (have since moved to OMEGA v12)
The phone just randomly reboots whenever it seems to feel like it.
It could be whilst taking a picture, it could be whilst using google maps, it could be whilst installing an app from the app store or just scrolling across the screen. It's basically rebooted through anything and everything and I've tried pinning it down to something but every time I think that I've got it sorted out. It crashes again whilst doing something else.
1 thing however has got me stumped. The phone has NEVER crashed whilst plugged in. If I keep the phone plugged in, it's never ever just rebooted on its own for me. Which got me thinking that it could be a faulty battery or some sort of voltage issue.
Coming from the 4.3 GE Edition ROM there are other people experiencing random reboots. But now I've just flashed over OMEGA v12 and right after flashing (I did a full wipe of course first) the phone rebooted whilst typing in my Wifi access key. After the reboot I was able to set my phone up and I did a reboot myself, then I went to the app store to add an account and the phone crashed AGAIN.
I'm totally over this issue with my phone. I paid a small fortune for it and I cannot rely on it at all. So I absolutely need it to work. I've had issues on 4.3 GE getting Mobile Data to work. I've had issues with it crashing and I'm just done with all of this.
Do you think that my phone is already broken? (It's barely 3 months old) Do I need to get it replaced under warranty? Can I even get it replaced under warranty, is there a way to even get my warranty back or reset the flash counter etc?
I'm just so confused guys I thought maybe it was my battery, and that my battery was faulty because I had battery percentages dropping and jumping around like mad. For example 15% battery left would actually have the phone turn off... and reboot at 0%. Then the light wouldn't go green for 'Fully charged' and the phone would sit on 99% or 100% but still not say 'charged'. In addition I could swear I had lost more than 10% of my charge in the blink of an eye etc.
I just bought 2 new batteries but they will take a week to get here.. and if the phone is still rebooting (and it isn't a voltage/cut out issue with the battery) then should I assume it's a hardware issue and that the phone needs replacing? Or could it just be a bad flash or something? The phone has at least a 2 year warranty. I don't want to replace it after just 3 months when I haven't even so much as dropped it once.
My recovery is PhilZ 5 Touch 6.0.4.0
I always check MD5 sums before flashing and do a full wipe:
- Wipe Data/Factory Reset
- Clean to Install a New ROM
- Yes
- Then Flash the new .zip file etc.
What on earth could be wrong with my phone?
I'll happily provide any more information, as I honestly cannot handle this happening and I have no idea what my problem is...
Thanks incredibly much for any help at all, what-so-ever.

I can only give you advice on some of the smaller issues that you mentioned. I haven't had a problem with reboots at all (i've flashed all manners of ROMs too, including the GE), so I'm guessing it is hardware related. You should get it replaced (if it still is messing up with the new batteries).
As for warranty, yes you can claim it back on warranty. To be doubly safe, restore it to stock: http://forum.xda-developers.com/showthread.php?t=2265477
Use Triangle Away: http://forum.xda-developers.com/showthread.php?t=1494114
Also FYI, rooting does not void warranty: http://matija.suklje.name/rooting-and-flashing-your-device-does-not-void-the-warranty-in-eu (assuming you are in the EU, not sure about other countries) (gosh i've posted this a lot today).
Thanks a lot buddy I am in the EU definitely and the phone is purchased from the EU. I am actually about to flash it right back to stock now to see if it stops the rebooting issue. I will just have to live without custom roms for awhile and such. If it still keeps crashing I will wait for the new batteries. If it still keeps crashing again after I get those. I guess all that is left to do is render myself without a phone for a week or two and have it repaired...
I wouldn't worry mate it sounds to me like a definite battery issue

Hi leijonasisu,
I've stumbled across your post after having experienced more or less the same issues as you. After trying many custom ROMs in the last few weeks, the phone has barely been useable for more than a few minutes until it randomly reboots. At which time, I must start over with the whole flashing process. My question is, did getting a new battery resolve your issue? Or did you just trade the device back in?
many thanks

Looks like it's better to restore to Samsung stock firmware first then start again from there,
But this will upgrade the the Knox bootloader also.
Stock firmware can be downloaded here, www.sammobile.com/firmwares
I fixed this ages ago. It was a battery issue, I'd bit my bottom dollar that it would be a battery issue for anyone else too, I've read a lot of stuff online about people who have gotten bad batteries with theirs. Swapped to 2 third-party and apparently larger batteries and never had an issue and never looked back.
Sorry for not replying back much sooner but I forgot about the thread.
Try another battery and if within a day or two you get no reboots then toss the bad battery and enjoy your phone! The thing is the battery (due to voltage issues) can make it look like it's the OSes fault when in actual fact it's just a faulty battery and voltage issues.
same problem here.. s4 randomly reboot..
I got the same problem.
The phone reboots every few minutes on me when i want to take it out of standby.
Sometimes it works for a few hours and sometimes it just reboots itself every few minutes or it reboots when i want to do something.
So ur all saying that a new battery could solve my problems ??

Hi, the OLD problem WAS caused by the faulty batteries batch (easy to recognize - the battery serial no was beginning with BD code).
Now, more frequently it is resulting from KNOX related issues.

Only one option then: read the ROM-specific threads, loo for feedback posts. If ROM would cause random reboots, you can be certain that it will be written there.
Same issue with gt i9505, random reboot, earlier i had gt i9500 that was flawless with all rom n root n with everything, but i bought gt i9505 and its random reboot like in every 30 to 20 mints, im totally pissed n disappointed ? plzz help....

Interesting will have to give this a go, also the battery option.
For months I was running on Lollipop custom ROM, the developer did an upgrade and then the SIM card removed error started. I went back to the old version was keep getting the SIM Card removed error. A few days ago went back to Original ROM for NZ 4.4.2 and I still get the SIM Card error and now the phone just reboots randomly.
Hello everyone,
I've had my note 4 over two years now and out of nowhere problems started happening after second MM update, model SM-N910F was freezing and restarting and sometimes was not able to boot normally and got mmc read fail.
I'm reading a lot about this problem in other forums and here, so hope someone could help about this issue.
No Success:
I tried anything from removing sd card, removing sim card, changing the battery, resetting the device, cleaning the cache, flashing the room through odin, flashing the rom with pit file and doing a re partition (Didn't tried Nand erase).
Success:
The only way that I was able to fix the freeze issue was by installing app called Wake Lock and enabling PARTIAL_WAKE_LOCK.
But using Wake Lock has its disadvantages. First of all you need to run the app all times which its not practical and second it wipes your battery because it keeps device and processor awake.
Please join this thread anyone who has similar issues with the aim to fix or bring the phone to an usable state again.
I also purchased my GN4 about 2 years ago and just recently got this error. This is really fishy. Wouldn't be surprised if it was Samsung trying to screw over all the root users and get us to upgrade to newer models.

Yes, I'm on the Canadian SM-N910W8 model of GN4.
I've been using the Wake Lock app for a few days now and it works perfectly, if you can get the phone to boot into homescreen that is.
For instance, when the phone shuts off due to low battery or an inevitable crash, sometimes getting the phone to boot up is a real pain in the ass because it doesn't boot up correctly most of the time.
However, one odd fix I've discovered is to put your phone and battery in the fridge for about 2-3 minutes and let it cool down completely. And then magically your phone will boot up properly to homescreen again. Activate Wake Lock and you're pretty much good until the next time your phone shuts off and can't boot. My phone will NEVER boot up to homescreen if it is even slightly hot in temperature. In order to boot, it needs to be cool.
I am highly confident that this is indeed a hardware issue, instead of a software issue. The mainboard fails to read memory properly which probably indicates that the mainboard needs to be replaced. I however cannot afford to do this so I hope that I can last atleast 2-3 years of my GN4 surviving through Wake Lock. :crying:

I really don't think it's an hardware issue but even if so, why this started to happen immediately after the update and why it only happens when the device goes to sleep or when we power on the device.
I also noticed the change on bootloader fonts and interface after the update. I'm suspecting that the problem is there.
Does any one has any thoughts about this?
It's a hardware issue. It's a bad nand issue in fact. You can find Reddit posts a mile long about it.
Anyways it will slowly get worse over time. Had to replace the main-board in my SM-N910W myself.

Is there any reason at all why it is happening I mean for the nand issue. I don't like the answer that is motherboard fault and we should replace it, which probably means replacing the phone. Is there anyone who can see deeper into the motherboard to find the issue. I also insist that this started to happen immediately after the second MM update.
I still have an IPhone 3G from 2008 and never changed anything on it. Isn't that ironic ?

It was a Bad batch of nand chip that started to go bad after a year or two. Note 4s started to drop like flies before April.
I think your in the 1st stage of Loss and Grief. 1st stage is denial.
If thats so than Samsung should repair our phones under warranty and not tell us we have to pay for the repair coz we installed custom roms.

Yes, I'm on the Canadian SM-N910W8 model of GN4.
I've been using the Wake Lock app for a few days now and it works perfectly, if you can get the phone to boot into homescreen that is.
For instance, when the phone shuts off due to low battery or an inevitable crash, sometimes getting the phone to boot up is a real pain in the ass because it doesn't boot up correctly most of the time.
However, one odd fix I've discovered is to put your phone and battery in the fridge for about 2-3 minutes and let it cool down completely. And then magically your phone will boot up properly to homescreen again. Activate Wake Lock and you're pretty much good until the next time your phone shuts off and can't boot. My phone will NEVER boot up to homescreen if it is even slightly hot in temperature. In order to boot, it needs to be cool.
I am highly confident that this is indeed a hardware issue, instead of a software issue. The mainboard fails to read memory properly which probably indicates that the mainboard needs to be replaced. I however cannot afford to do this so I hope that I can last atleast 2-3 years of my GN4 surviving through Wake Lock. :crying:

I've already swaped a few main-boards. Ive even put a international exynos n910c main-board in a broken canadian snapdragon note 4 and its works perfect.
If anyone needs help just pm me.

I would be more interested in understanding how come so many Note 4 devices started acting up around same time mark...
This is definitely a hardware problem with the motherboard. Mine started giving the same symptoms 2 weeks after the 6.01 upgrade. Wakelock made it stable but after Samsung replaced the motherboard it is so much faster and no issues at all. I wonder if this is a faulty NAND issue whether the 6.01 upgrade and the way it manages memory could have triggered it. Certainly strange but it need Samsung to fix it.
I am also having same problem.
I was using custom rom and it was working fine without any lag or freeze suddenly one day my Note fall from bed to ground and since then it is not working properly i thought its the ROM so i reverted back to stock MM rom flashed via odin.
Reset everything erased everything but the problem remains same.
At present i am on stock with hardly any apps just FB and whatsapp.
But my device is so slow and keep lagging and sometimes it becomes very hot and restart itself.
I dont know what to do now. i m on 910 G snapdragon.

Sorry to hear that, as for now jut install wake lock and enable partial_wake_lock so you can use your device until it fails completely
Mmm. I was thinking to root my phone (4month old still under warranty ) i think i changed my mind after reading this ?. Thank you guy's for the warning

Same issues, I downloaded the wake lock and so far so good.
I have the same issue also guys and it started a week after updating to Marshmallow.
Phone worked perfectly fine for 2 years prior to this. So I highly doubt its a hardware issue and more likely a software/firmware problem.
Phone seems to have issues whenever the screen is asleep (hence why the wake lock app seems to help with this problem although not a proper solution)
I'm hoping Samsumg can release a patch fix for this as I truly love my Note 4 and would like to keep it for some time yet.
have anybody tried going back to Lollipop?

I was thinking about that! but I saw on other threads people downgrading with no success.
This happens only when I install any custom rom...the phone works fine with x720 5.8.018s version...anything apart from that device will shut down every 2-3 minutes ...very strange behaviour ...any one has any idea ?
any custom rom , android 6 or 7 , AOSP or stock based, it will boot fine and after initial setup , it will work for 3-4 minutes and then suddenly device shuts down. .. when i boot it up again , same thing happens, in one minute shuts down.
if i flash 5.8.018s stock rom , everything works fine....and it doesnt shut down...
After device bugs, my phone finally was restored into x720 stock ROM (i have x720). On boot it worked below 1 minute and reboots. I had to do clean data. Also booting x720 ROM into x727 is not too good idea. Maybe you should try to do more wipes?

I did all the wipes i could , cleaned all kinds of data... it was US version 5.8.018s originally and i tried to flash Omni ROm first , and other ROMS , all had same issues, so i thought going back to the stock US rom , but since US version of 018s is not available anywhere, i went to chinese version , and it works perfectly , no reboot/shutdown...... I have used number of phones and installed 100s of ROMS , i have never faced soemthing like this...i hve even used leeco pro 3 before, with all custom roms and no problems.

Ok update...i downloaded x720 021S and 023S and updated using in build update option..(local update) , and it worked, 23S is working without any shut down...so i guess, it is problem only with roms flashed thru TWRP

Usefull information, thank you very much.
Nearly the same problem here: My X720 is only rebooting sometimes, but more often switching off directly (vibrates one time and switches off). While the phone is in that status, the battery is discharging. I can only reboot the phone by holding the power button for about 10sec or to TWRP. Two times I was rebooting the phone and some (not all) settings were restored to default - reflashed the rom... Another time rebooting the phone it hangs in the booting display, did not get it booted completely again - reflashed the rom.... Very strange behaviour and don't know why this happens.
But for about the last month, the phone is only switching off and I can reboot and use it for an unspecific time.
That all happens with several ROMs - currently I'm on ResurrectionRemix 5.8.5. This is the most stable custom rom I have tested, but anyways the phone switches off in irregular periods. Sometimes the phone is about a day alive, sometimes only a few hours, sometimes below an hour. When I'm playing HQ games I think the phones switches off much faster, but not sure.
I'm also not sure - I do not have used the stock rom really long after I get this phone (was CN 5.8.018s I think) - but my feeling is, that the phone was definetely more stable with the stock rom.
Now after finding this thread, I will give the stock rom another try. Would you be so kind as to describe the process of going to the stock 023S a bit more in detail? First flashing the 5.9.021S for the x720 ROM throught TWRP and after that using the build in update option (rename file to update.zip into root folder)?
Thanks!

You do not flash a 21s update twrp that may brick you.
You have to go stock and flash with stock recovery.

Does anyone completely solved the shutting down issue on x720? I remember the same issue with the stock rom when i was getting the phone (5.8.018). but this rom could have been a shop rom, cant remember.
For me it seems that the issue happens more often whenever the phone uses more performance. Playing HQ games let the phone shut down after about 1-3min. doing nothing on the phone, it remains for about a day. Weird behaviour... will try to flash the stock recovery via fastboot and then a stock rom (no shop rom). hopefully it will improve the behaviour or even better solving the issue.
Sounds like a hardware issue. As for me, I have a couple of screen issues--I usually have my LeEco Pro3 Elite connected to a charger, and I sometimes don't use it for long stretches of time (say, 8 hours) because I have another phone as well. Once in a while, during those times the screen refuses to turn on. Sometimes the fingerprint scanner wakes it up, other times I have to straight up reboot the phone using the power button (I have to keep it pressed for two whole minutes for it to wake up the phone). Pretty annoying, dunno why it's happening. Could be a loose screen cable.
Now, if your phone is shutting down every few minutes no matter what, it could be a battery issue. I say this because I had a similar issue with an old iPod Color from 2005. The iPod would shut off every few minutes even when plugged into a charger. I changed the battery and it stopped shutting down.
Hopefully it's not a motherboard issue because replacing a phone's motherboard is never easy.

I don't think gameplay should affect the phone negatively at all. Especially a phone with a Snapdragon 821, a 14nm processor with efficient cores, for crying out loud. I play Fate Grand Order, a pretty intense 2D online game with 1080p graphics for 5 hours straight on my LeEco Pro3 Elite (Snapdragon 820) without it heating up at all.
Again, seems like a hardware issue because no phone with a Snapdragon 821 or 820 should be doing that. Especially while gaming.

Thanks for the information.
Could be possible... If I'm shaking the phone like a cocktail-mixer, it feels something loose inside it and this could be the battery of course which could be not fixed correctly. But I am sure, that this issue has also something to do what is happening on the phone currently. Sometimes I am going to bed and the phone does not move for 8hrs, it simply lays on the table. In the morning, it is shutted down. Need to hold the power button for about 10sec to restart the phone (usually hold 2sec to power on). Sometimes (not really often) it warm-starts automatically.
I think this could be also a memory issue or internal storage. Yesterday I was playing a game (Bowling by Jason Belmonte) and after 3min, the phone hung up, display remains on, no reaction on pressing the hardware buttons, waiting 5min... nothing happens. So I pressed the power button 10sec, phone seems to reboot normally, but it take a bit more time in my oppinion. Now after entering the pin, some phone configurations were resetted to default, but not all. Playing this came, it sometimes happened, that the phone switches off (with one vibration). Rebooting with a 10sec press and it runs again normally. This time phone hung up and some configurations were resetted to default. WTF?
Today I have played Hmmsim 2. Phone hung up again, pressing the power button 10sec, phone begins to reboot, but rebooting never finished (waiting for about 1-2hrs). Long Press power button (10sec) to try to reboot again - same behaviour, never ending ROM loading screen. Wiped to factory via TWRP and the phone reboots again, but all configurations lost, like freshly installed rom. OK, whatever, using the google backup for apps and so on... when installing the apps in the background, the phone reboots about 3-4 times, app installations not finished. Cancelled and shutting the phone down to TWRP, where I am now...
What I will try to say is, that whenever the storage or memory is used to much or something like that, the phone begins with that behaviour.
And now I am thining about what to try next. I think I will try to flash the stock recovery via TOOL ALL IN ONE then flashing a stock rom like 5.9.023S.
I am still not sure of a hardware issue...

The easiest way to tell is if the issues were occurring before you flashed TWRP. Were they? This is why you always wait a couple of months before modding your device. Otherwise you'll be stuck in a loop of doubts. By this I mean you'll be convinced that the issue has to do with your custom ROM or kernel rather than your device's hardware, but you have no way of knowing for sure because you never used the phone enough on stock firmware.
I was like you... my unmodified Zenfone 3 had a screen flicker issue and a headphone jack issue that I was convinced was a Nougat problem. I upgraded from Marshmallow to Nougat immediately after getting the phone. After a lot of research and posting threads on the Zenfone forums, I realized I had a hardware issue on my hands. The screen had to be replaced for the flickering to stop, and the headphone jack had been gimped to 0.3v by ASUS for some reason. I quickly sold the phone and got my LeEco.
Here's a thread I made on XDA about my screen flickering issue. It's a hardware issue: https://forum.xda-developers.com/zenfone-3/help/ze552kl-screen-flickering-lowest-t3660643
I've learned some important things from that experience: it's easy for your brain to trick you into thinking you've got an easy-to-solve software issue on your hands, when in reality you've got a hardware issue. You need to start making arrangements for a replacement device and get video evidence of your problems to show to the seller ASAP. Because that behaviour isn't normal. Now I hope you do have a software issue on your hands that the stock firmware will solve, but who knows. Be prepared for anything.

Thank you very much!
I am sure that the phone was doing the same on stock rom, but maybe fewer times. I have flashed a stock based rom now (Turbos mini 5.9.023s) and the issue still exists, but now the phone reboots normally more often than going into edl mode (emergency mode). I have found an old thread here on XDA and the issues described there sounds nearly the same. Finally the user in this thread also had hardware issue.
I believe also in a hardware issue, but I am still not sure. If I am looking to other threads regarding similar problems, there is always some regularity in the behaviour or the reported issues. In my case these rebootings (usual reboot or reboot to EDL mode) are definetely very unregular. On the TURBO Rom, these reboots happen definetely more often when the display is off and the phone sleeps. On the TURBO Rom, playing games seems to be helping lasting the phone a bit longer, the completely differnce to ResurrectionRemix Rom, where the phone was lasting longer when doing preferabely nothing. The issues are so inconsistant and this is making it hard to believe, that this is a hardware issue. Why the hell is the phone behaving different on every ROM - if it's a hardware issue, the occurred problems should have some regularity.
As I didn't have an OTA update option on the stock rom, I'd found out that this could be a "shop rom" (5.8.018), which is not the best choice nor for the first month(s).
I'm from Germany and I do not really want to return the phone to china or east asia for repairing (bought at banggood). This could take a very very long time. Changing to a new one could be also difficult because there are hardly any more devices out on the market and I need to return it for the change too.
But I am slowly at my wit's end and before these issues are making me more and more crazy, I will accept a problem with the hardware.

If your issues were occurring from the moment you got the phone, you know it's a hardware problem. Your seller sent you a defective phone and you should at least try fighting for a partial refund. If you paid through PayPal, open a dispute. If you paid with a credit card, ask for a chargeback. Now, the shop you bought it from might ban you for initiating a chargeback, but it's probably worth it. Or you could just cut your losses and move on. Maybe donate your phone to a dev who wants to try something crazy. :good:

Oh snap, it's a Banggood phone? I bought my x722 from Banggood. No glaring issues other than the screen one so far, but this does worry me for the future. How long have you had it?
This is the problem with Chinaphones. They're cheap, they've got good specs, but you can't guarantee quality. Especially with now close-to-defunct brands like LeEco. If you're still okay with Chinaphones, get a Xiaomi next. Probably the most reliable Chinaphone brand out there, next to Huawei. And try to buy from an official source. I heard The Solution Shop in Europe sells Xiaomi phones for cheap (?). And always remember to record your unboxings and document all issues from now on.

Admittedly I'm not sure at all if this issue was already present after starting the phone for the first time. One of the first things I have done during the initial setup wizard was using the integrated data transfer app by LeEco (scanning a QR code with the old Xperia Z, downloading app to transfer data to the x720). This app establishes a Wifi direct connection between both phones to transfer the data like apps and other stuff. This transfer process takes at least 6-7 hours and during that process I am sure that the phone was not rebooting a single time. Maybe a specific app or background process of an app causes this irregular rebootings. I have not testet this. I have installed the most common of my apps also using different custom ROMs later.
On the current ROM (Turbos mini 5.19.023s) I have now looked into the last_kmsg.log file severel times after the phone was hard-rebooting (not to emergency mode - the phone is switching down to emergence mode really rarely since I have flashed the stock based ROM) to debug for a kernel problem and the power off reason seems to be ""Triggered from PS_HOLD (PS_HOLD/MSM controlled shutdown)". In the log file I could also find some "kernel panic" entries. So I have a little gleam of hope that the issue is not a hardware problem. I have to test a bit more with the stock recovery/ROMto gain a better knowledge of the issue. I think I will post this into the ROM topic to ask a developer.

Finally - I got it working without any problems now!
Happily it seems to be not a hardware issue. I have flashed the Grossoshop ROM and Recovery via a provided .bat file. This .bat file has flashed the recovery first via fastboot, then the ROM via fastboot. This Grossoshop ROM was based on 5.8.018s I think. Then I have updated TWRP Recovery to the latest version via TWRP itself (flashed the new image). Then I have flashed Mauro's 2.2 (which is based on 5.9.023s) and it is running great! Super performance, no extrem battery drain, no reboots, all is working (except the chinese design downloads as I cannot create a Leeco account from Germany). But now I'm satisfied. :good::laugh:

Another time rebooting the phone it hangs in the booting display, did not get it booted completely again - reflashed the rom.... Very strange behaviour and don't know why this happens.
But for about the last month, the phone is only switching off and I can reboot and use it for an unspecific time.
Thanks!

My x720 has done the same to me a couple of times now, Vibrates once and turns off and I have to hold the power button for a few seconds longer to turn it back on again which is odd.
The battery was charged over 50% % 70% at the times it happened and I wasn't even using the phone, It was just sat on the table in front of me.
I didn't have any problems at all until a few days ago when it first shut down.
I'm using Oreo - AICP 13.1 from here - https://forum.xda-developers.com/le-pro3/development/rom-aicp-13-0-pro3-aka-zl1-x727-x720-t3698058
The problem now is I don't know where to start troubleshooting When I get time I am planning on a clean wipe and fresh install of AICP again to see if that solves the problem
When using this ROM does your phone heat up a lot.

Did you manage to fix the problem somehow?
