[Q] Unique Nexus One power up issue - Nexus One General

Hi Moderators,
Please feel to delete or move this thread, if you find it repetitive. Apologies for starting a new thread.
Hi All,
I have a unique issue with my Nexus one. Sometimes it fails to reboot and then does not start even pressing power button multiple times. Sometimes it starts but then screen does not come up after the display time expires. Whenever it is ON, power button works good, ALWAYS. When it goes into the weird state, I am not able to put it in recovery mode as well. Whenever, I am able to put it in recovery mode, power button ALWYAS works good. Also I have seen that sometimes, even after boot-up it is not able to detect the SD card even when battery is at around 30%.
I have tried all the methods I could find related to "Nexus One power issue" here on XDA as well as via Google search. Sometimes the "remove battery multiple times while plugged into AC" works but at times it also does not help either.
I visited the local HTC service station. The guy there showed me that the small strip of Litmus paper on battery and phone has turned reddish. For normal phone it should be white. This indicates that phone was in contact with something acidic in nature. I tried swapping batteries with my friends and colleagues, but no luck. I have replaced the power button strip of my phone which seems to be trouble some as per the discussions here.
I have tried CM7.x, RCADS, MM super hybrid, eVil's desire port and of course stock 2.3.x ROMs. All seem to have similar issue one or another time. I have also tried Amon_RA's 2.2.0 and 2.2.1. Somebody told me to try with CM6.1 which I will try now if I am able to boot it in recovery.
My warranty is long gone, BTW. Also I bought my phone from US and it is not possible for me to go there again in near future. This issue cropped up approximately 3/4 weeks back. I have default radio.
Having said that, does anybody know what could be the issue with my phone? Has anyone faced such an issue?

Hi Moderators,
Apologies for posting this thread in this sub-forum. I forgot that question threads should be in Q&A section. Having said that, if its not too much to ask, can you please move this thread to Nexus One's Q&A sub-forum?

Just update d firmware wit any of the ones which r available here...m pretty sure this ll solve yor issue as I think its related to software not hardware...

Thanks a lot for your suggestions. I somehow manage to put my Nexus one in recovery mode by pressing power + volume down buttons multiple times. Then flashed the radio 5.08 on it. I already have CM 7.x ROM.
With this combination, my phone is working good so far. The power down issue would have reoccured by now. So it looks like my issue is resolved. I will use it for 24 more hours and come back if I am able to hit the power down issue again.
Once again thanks for the suggestions. As usual, XDA rocks. Had been experiencing this since good old Windows Mobile + HTC Touch days :-D.

I tested my Nexus one for past approx ~36 hours. In this time, I was hit by the issue mentioned in this thread twice.
Out of those 2, 1 was probably caused due to a soft reboot as I was able to get some output from cat /proc/last_kmsg but could not save it for sharing. The other one did not had last_kmsg entry so I am not sure what caused the phone to go haywire. The battery charge was ~30% when I booted it next time.
Now, I am on CM 7.x stable + 5.08 radio + Amon_Ra' 2.0.0 recovery and I explicitly have wiped the cache and Dalvik-cache via recovery. Since then, phone seems to be working OK. I will keep this thread updated if I am again able to get into the "Not able to power-on with power button" issue.

[Q] CM7 dual boot on NC: The screen will start to move on its own

I found that every so often my screen will either start to move on its own or will no longer accept my finger press's. I can fix it by hitting the power button and then turn it back on and it will read again. is there a way to fix this so I don't have to press the power over and over again?
I've had this same problem with my Nook Color (which is about a year old). I solved it by installing a newer version of the ROM I was using. If you still using the stock software that came with the device try doing a factory reset as this problem seems to have evolved and wasn't inherent to the device. Good luck!

Well odd thing I was messing around with Themes this weekend and the problem disappeared. it doesn't move like it was, but now I find that some of the more intensive games seem to slow down a bit now. Doesn't happen often but enough. Hopefully all this completely disappears once ICS is stable

ICS LOCK/STANDBY power button doesn't turn on screen !

I recently wiped all of my phone (factory+cache) and installed the latest 4.0.3 official update from SAMSUNG.
I also enabled the FULL DISK ENCRYPTION while doing this.
I am now waiting to decrypt it to see if this problem persits if I turn the encryption off.
The problem is that if I leave my phone locked for a few hours/minutes it randomly won't turn on the screen again, when I press the power button.
A hard reboot (holding) fixes this everytime. But this is not a fix, we all know.
It never happened on Gingerbread 2.3.5.
I am beginning to suspect there's a bug in the ICS firmware, although it's 4.0.3, it could slip through.
It's hard to say what's causing the trouble. I have connected the phone to USB now. Waiting for the symptom to show again. I assume I can get a good logcat.
adb shell logcat > logcat.txt
So I'm waiting for an error / event of POWER button at this moment, and will keep logging till it produces the same error again.
Regards,
That's called the black screen of death. It's an ICS bug. For now, rebooting seems to be the only solution ice seen on xda.

I can't believe this ! Is this a SAMSUNG or an Android/ICS problem ?
My version is:
4.0.3
IM74K.XXLPQ
Any custom ROMs addressed this issue or how can you avoid this on ICS? Is the only solution to go back to Gingerbread ?
Hi guys, hope your well.
I am having a similar issue too. I am on Hydrogen AOKP Rom, and I get exactly the same. However, apart from just the blank screen, my phone gets extremely hot too.The only way to get it back on is to remove the battery. Very annoying!!
I cant seem to figure what it is. I have tried to search here on XDA for the resolution but to no avail. Could it be the Kernal? The Modem? Tweaking via SetCPU? or a combination of all? Atleast if I could get pointed to the right direction that'll be a start! lol
Are you guys getting the overheating problem too?
Its a bit like continual posting in the wrong forum nobody knows why ??

No overheating (yet) you can help if you can keep logcatting through usb cable till it lock/standby freezes and your screen won't come on when pressing power ..
Install SDK + Drivers, write in commandprompt:
adb shell logcat > save.txt
Wait for the error / freeze where screen won't come on.
Then paste here or upload somewhere might contain a lead to a solution!

Nah!
It's there on all the kernels. I myself am a Siyah user.
I moved back to GB for this weird and terribly serious issue, but that time i didn't know it was a common problem.
This is ICS' best feature for sure.
I really CAN NOT believe how this issue is NOT yet known well and haven't brought in to front line. Google knows about it and yet I haven't seen any official statements about it. How ****in unbelievable or not perhaps? Google way?? Well **** it.
Utter Nonsense. What i wonder is, really, does any Android user actually use the phone but show off only??
I can almost reliably reproduce this problem.
I'm on ICS LP7 stock XEU version. When I have downloads running with Ttorrent, there's an almost 50% chance that the screen will not turn on once it goes to sleep. The phone is not frozen as my downloads continue to run; just that nothing is being shown on the display. If you hold the volume down button you will feel the phone vibrate to tell you it went into silent mode, which means the phone didn't freeze. After about a minute or so if I try again everything will work as normal, until I put the screen to sleep again.

Do the logcat as I provided the correct command to extract it to a file.
Then do your torrent thing, and make it crash- so we can debug !
Used to happen, since I installed latest hydrog3n-ICS rom (13-05) never had those again!

Hi,
It happened to me as well after the ICS update and I tried to plug the AC charger to see what happens, and surprise...the screen turned on .
It's not a fix (especially when away with no accessories) but it's better than nothing, hope this helps; also you should try plugging the USB cable. Tell me if it helps.
Thanks,

Yep,I mean under volting, you need to look your kernel, and I think it doesn't work fine because your kernel has under volting so much.

[Q] Does anybody have this issue?

My nexus 4 was bought about one month after it was released .
I didn't have this issue in the first three months ,but recently ,about in the past one month ,it occurred kind of frequently and randomly.
Here is the issue:
I lock the screen and leave it there without using .When I am ready to use it ,I cannot awaken the screen even after I press the power button several times, both short and long press ,as if my phone was powered off ,even though I know its power is still 50 percent or so. After a series of random press ,I give it a long press ,then it gets rebooting .
I have been searching on the internet and many Nexus 4 users have this issue ,however, nobody can tell exactly what causes this problem .Some say it is caused by snapdragon batteryguru and some say the battery is not firmly installed .
I don't know whether you guys have ever come across this issue ,what is your analysis about it and how you solve this boring problem...
Glad to see that I can find solutions here...
My nexus is running original android 4.2.2 and is not rooted.
sleep of death. long press (10-20 seconds) powers off/reboots the phone. can be caused by phones software, undervolting and apps.
i haven't got any issues like this, have you installed a rom? if you have try another rom, also remove battery guru as suggested

SlimBean 4.3 Screen Wake on Standby

***TL;DR***I know now that 4.3 has this bug and it is something we will deal with. I understand the causes, but the problem is buried in the kernel vs the ROM, you can still read my semi adventure but I wanted to make this edit to save you time if you think I found an answer. Overall WIFI is a huge trigger for screen wakes along with shotty or chattery reception.***
First off SlimBean is pretty much the best ROM I've dealt with, so many options, faster then I've ever experienced, and sharp looking. I've been sharking around these forums for 2 years afraid to ever make a name and post due to my lack of knowledge. I love the search options for finding answers that this forum offers to visitors and I've surely used it to root an old AT&T Atrix 4G and now my current DD the Glacier. Now I feel as though I have a little bit of sense of what the heck I am doing and would like to share my path to figuring out how to make SlimBean 4.3 work for me. Who knows maybe this may help some people that have similar problems.
The problem::: On a SEMI clean install of [UNOFFICIAL]SlimBean 4.3 \\ Nightly \\ 22.08.2013 I noticed the Glacier in standby would suddenly illuminated with light although the screen was black. It was enough to light to catch my eyes as I was starting to fall asleep. I ignored it until morning then paid attention to it happening all day at work on and off constantly with the WIFI off and just mobile network, then mobile network off, reboot, nothing seemed to help and I couldn't bare the thought of the phone's screen just on all the time.
After reading threads about HTC's possibly having bad screen made from Taiwan I was in disbelief that it was the Hardware as coming from a year old version of MIUI, I never had a problem with the screen. Leading to the idea it must be a software issue / user issue in which I must of rushed the install of the ROM or it's a quirk in 4.3.
Prior to reinstalling the same ROM, I went with trying other similar ROM's finding [UNOFFICIAL] Carbon 4.3 \\ Nightly \\ 26.08.2013 literally was just released, also a super customizable fast ROM. Everything went smooth until I played music through headphones and the illuminated black screen was back. Now I'm definitely convinced it's the software so I move on to the source code of these ROM's ev_glacier-nightly-2013.08.27.
Ev_glacier-nightly-2013.08.27 Had no screen wakes after 2 hours idle on mobile network only. I wasn't in a location with WIFI as I believe a network with a lot of information chatter may be causing these standby black illumination wakes. Back to SLIM.
SUPER clean install. 1) Format SD card completely 2) fresh download w/ checked md5 of Slimbean 3) Full Wipe "wipe data factory reset" "wipe cache" 4) format/system & format/cache manually just in case 5) Clear Dalvik 6) And fix permissions since although I believe it has no point but it's just so easy to click just in case. Probably doing things double.
Here I am now.. Slimbean is back and nothing but the .zip has been installed along with updating Nova Launcher. I am waiting to reinstall GAPPS so I can first isolate this problem within the ROM itself. What I am noticing is on just mobile network 2g/3g/2g+3g I do not get the phantom wakes, but with WIFI on it so far is only happening about 20-30 seconds after the phone drops into Standby and at least now it's not long lasting, just a few screen black flashes and it's gone. The entire 20 minutes or so I've been typing this, keeping an eye on the screen it's been quiet. Progress is being made.
Now I have thoroughly read up on and used Better Battery Stats, Wakelock detector, and Greenify to help isolate problems prior to the clean install and am waiting to install any Google apps (play store) up until tomorrow so I can pay more attention to my phone and make sure it's just a WIFI wake lock causing the screen to illuminate black. Also was toying with the idea of installing 3.0.64 kernel. I'm curious as to see if it's not just the WIFI wake lock, but all wake locks that actually wake the screen. Once I'm ready to install the play store I'm going to start combing through the device using these fantastic guides and the aforementioned apps...
[GUIDE] The Total Newb's Guide to Wakelocks ::: [HOW TO] Fix Your Skyrocket's Battery Life ::: [GUIDE] Insanely Better Battery Life When Idle
My goal with this long post is to share my experience and also commended these developers on these awesome ROM's. I will post much shorter updates on how I fixed or found the exact problem. Mainly after searching I saw similar issues but not this direct "random black illuminated screen" problem. Thanks, and be sure to call me out on anything contained in this post.
the waiting game
At 9 hours from 100% charge, I'm at 40% battery with on 1.5 hours of screen time. I went through all my settings and disabled all sounds and haptic feed back. I have yet to install any apps and am running off the bare bones of just the ROM. WiFi & 4g mobile data were on all night with the screen flashing only if I used it then locked it with the power button.
Thinking I can live with these timeout 2-5 flashes, I start browsing the forum from my phone, put it down to get ready for work, look back at the phone as it is flashing black screen rampantly on it's own. Then it holds the black screen for a solid minute or two.
WiFi chatter wake lock must be doing this... Reboot to recovery - wipe dalvik - wipe cache - reboot phone. Now to test just 4g network, flash happens on first screen lock, but not as rampant. Hmmm. My next step will be to wait for full battery drain / charge then I want to try the kernal I mentioned above. 3.0.64 kernel.
Funny stuff
Realizing the Kernel I wanted to flash doesn't work with 4.3, I hope at least some of the 86 people that viewed my post got a laugh. Even the older version of SlimBean causes the random screen flashes and the screen on while charging even with the ROM settings for such off. WiFi seems to be the greatest cause. It's as if wakelocks are actually being represented as screen flashes since the kernel is so powerful.
I just don't want to use the CM ROM...
I'm going to dig around the forums further and type in different key words of my problem just to make sure I didn't miss someone already answering this question. Slim has all the functions I always wanted out of my droid and I'm dead set to make it work...or just live with screen flashes I guess.
Hope this is a comedy for someone.
only other link
I've found on the issue I have.
http://forum.xda-developers.com/showthread.php?t=1148057
Non-Stop ROMS
1) SlimBean 4.2 & 4.3 Both have this black screen flicker / black screen wake / black screen on while charging.
2) Carbon 4.3 Had it black screen on while listening to music / black screen constant while charging
3) Evolve 3.3 based of 4.3 seemed to work fine, but I wasn't a fan of the larger Icons and screen, similair to CM 4.3 so I didn't leave it long enough to test...
4.3 CM 4.3 black screen wake almost constant / black screen on while charging... also didn't last long to really test everything.
I am down the river if I want this to just go away. I have installed all these ROM on a completey clean formated SD card each time
I'm sticking with SlimBean as it has the looks and reacts like I expect my phone to. After doing some more searching and after a little time has passed for more 4.3 development there may be a kernel that will work better for me.
Oh here is another dead end I've found... http://forum.xda-developers.com/showthread.php?t=2185747&page=3 [KERNEL] Fixed the flickering screen problem,CM10,CM10.1,SENSE3.6 4.0 4.1 That goes no where...
wifi
WiFi is the biggest culprit for the random screen wakes. I've just been living with it since I dig the slimbean 4.3 ROM so much. Thought I might pop back on here to make some closure. I worked on removing some apk's from the already minimal gapps I installed and will soon start a separate thread on just that. As long as after searching I don't find the same info I figured out.
I think you've got the screen flicker bug.
Try flashing the .69 kernel, it claims to stop the flicker.
Also I know it's got something to do with the WiFi. I know a little about it though.

I see you all over the place when it comes to Glacier threads. Today at work I was searching around for a download link. I read through a ton of other ROMS threads hoping it was buried in the comments somewhere. So far I only turned up and old thread with a dead link and a couple of other threads you mentioning to other people to download the .69 KERNEL which I am guessing the full version number is 3.0.69, if it's not then there may be my first problem in finding the link...
*edit
this is the main thread I keep finding, you have so many other kernels on there

I have a little idea about the screen flicker.

All the Kernels in the Glacier Bible page you have been keeping up seem old. I'm nervous to try one since they obviously seem like they won't work. I'm game to try what ever and post on here my progress so if anyone else stumbles upon the issue they can guide their way through it.
I've been searching "kernel 3.0.69", "kernels 4.3 roms", "jb rom kernel", "4.3 jb kernel", sometimes including the term "glacier" or "MT4G" with little to no luck between XDA and just google itself. I always just find ROMS that just mention the kernel but have no downloads.
Reading your older posts I see that youve already tried the kernel.

I tried 3.0.64 kernel, not this mysterious .69 kernel you have mentioned. If you have a link or mirror of it I'll be glad to give it a go.
___________________________________________________________________________________________________
Found how you added the 2 kernels to the Bible page, I just flashed .64 again and I'm nothing but bootloops. I'll give .62 a chance since now I'll have to re-flash Slim.
___________________________________________________________________________________________________
make the double bootloops with either of those 2 kernels. I waited like 5 minutes, restarted the phone to see if it would boot and it just stayed on the slim splash screen. Of course I wiped dalvik and cache before installing either.

Oh yes, I head that already downloaded on the SD but the name CM_SENSE made me think it was a ROM not a kernel. The .66 kernel link is dead, but the .58 flashed & works but there is still the flicker on 4.22 SlimBean. 4.22 is so lame compared to 4.3. Even if there wasn't a flicker on 4.22 I don't think I'd keep it. Those big ICONS are just too much. I think that's why I like Carbon also. Anywho...
My addiction to messing with my phone is always in conflict with work. As if I don't have enough problem solving to deal with outside of cell phones.
I am going to try out the recovery I see in your signature, Recovery : 4EXT 1.0.0.5 RC8, just to see if it makes a difference. If you have the same phone without the same problem I must then eliminate the different variables to find the true problem. I found a "how to" and am either going to put in the time in a couple of hours or tonight. Then I'm going to start the rounds of testing ROMS / KERNELS all over again and I'll post my findings here.
I appreciate the back and forth, I actually got a can't thank anymore message because I used up my 8 yesterday~
Living with it
I've been just living with the screen flash. The ROM is just to sweet to give up. At some point if there it a completely stable 4.3 I may upgrade.
On a regular work day I don't have any available WIFI, so I toggle it off then reboot the phone every morning. I usually get a random screen flash everytime I manually lock / turn the screen off and that's it. With WIFI on I get random flashes at random rates and for random lengths.
Playing music invokes these random black screen wakes also, I've stuck to my old blackberry as my MP3 player...I know that statement seems extemely wrong and against all sciences, but the 9780 bold works perfect as a music player. They had the long-press song skip in the volume button well before anyone added it to Android.
If ever I find the correct ROM / KERNEL combination, or someone else figures out the problem and I find it, I will post it here. This winter I am going to get more into understanding & compiling roms + digging through code so maybe I'll find it myself...ha!

leeco pro 3 x727 shuts down after few minutes

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.
Their threads already on this.

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:

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.

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.
