Phone keeps rebooting randomly without power connection - Lenovo ZUK Z2 (Plus) Questions & Answers

I'm sorry if this has been asked before, but I couldn't find a definite answer anywhere. So my Lenovo Z2 plus which is rooted and was flashed with Flyme OS. I was playing pubg and halfway through the game, my phone rebooted. I thought maybe my battery drained but I tried to reboot anyway thinking that atleast it will boot up to show 0% battery, but it didn't. After plugging it in, it would work again for sometime then randomly reboot. And when I would reboot it myself, it stops right after the logo.it only moves further if I plug in the charger. So if it's a battery problem, why does it always reboot at that precise moment. And when it reboots randomly, it's not even hot - the screen, the back, anything. Sometimes it works for hours and would suddenly stop, sometimes it works only for a few minute after unplugging. There's no specific app that triggers this. I even changed the ROM to AEX 5.8, and the problem persists. Is it genuinely a battery problem or is it related to bootloader or anything. Because it does not reboot while in twrp. Any help would be appreciated

Bro I'm facing similar problem.
Did you get any solution?
Mine also started with PUBG.
My phone gets hot first and then keeps rebooting, so I switch it of and wait 10 mins .
I even clean flashed AEX 6.6 Rom, but it still persist.
Now if I use my camera also I can't click a single picture, it just starts rebooting again and again.
Please help me if you have found any solution.

Okay, so guys - I am using POCO F1, Started having this same issue yesterday, on the internet, I found - this is a hardware issue, and the solution is to get a new battery,
So I went to the Xiaomi Service center, Their engineer said the same, this is a dead battery issue. So I bought a new battery - and the phone is working fine.
so Final Solution = Get New Battery

LG G3 D855 shutsdown on its own

Hello,
So I bought a G3 the day before yesterday and yesterday was my first day with it, and for that first day my phone had shutdown twice on its own. The first time was when my phone was lying on the bed and doing nothing, it had around 50% battery and was not hot or anything.
The second time was this night i don't know when, i have put my G3 on the charger and went to sleep i woke up and it had shutdown.
I didn't made factory reset when i got i from the box which i will when i come home from work and hopefully this will fix it, but does anyone have a problem like that? If is something serious i will be disappointed to return the phone.
p.s. My previous phone was galaxy s2 and had this king of problem only with custom roms and kernels, but i have not put anything on the G3 yet, except activating the developers options and had switched it to ART and the first time the phone had shutdown i thought that the art was the issue and switched it back to dalvik, the second time though was on dalvik.

I have the exact same problem. The past few days when I go to bed and wake up in the morning, the phone has shut itself off. I haven't rooted or installed any custom roms.
I would advise you both to take a factory reset, only install apps you need for a few days and see if the problem persists, if it doesn't install your apps back one by one as it may well be a particular app causing the reboots.
If you still get reboots after the reset and with no apps installed then you may have to take the phone back to swap it.

Yes as I said in the first post the factory format and hard reset will be the first thing that will be done as soon I am at home. About the apps i have pretty much basic apps (facebook, messenger, soundcloud, etc) all from the market except smashhit of which i have the apk and installed from the internal memory.
Except those apps I have 2 mp3s and some wallpapers and nothing else, becouse when i got my phone it was late on the evening and i had no time to do anything else. So the phone is pretty much out off the box and I was verry frustrated when the secound shutdown happened, becouse i tought the first was from the ART runtime.
Anyway today I will have more time to spend on the phone and we will see what will happend.
p.s. The phone does not reboots, just shuts off.

Is it definitely off or is the phone just stuck on a black screen? It is quite common on some devices when something is not quite right for the kernel to be unable to wake the phone up, the phone is still technically on but stuck in deep sleep.
does holding the power button for 2 seconds turn it on? or do you have to hold it for say 7-8 seconds?

It is definetly shut down around 2 seconds(the normal time to hold the power button to turn on) it turns on and work perfectly and does not show anything suspicious in its behavior, it's super fast, not laggy and etc, may be a little high on ram consumptions but with this havy skin i think it is normal or could not be normal idk, the ram consumptions go from about 1,2GB the lowest i have seen to up to 2,3 the highes i have seen.
Anyway about the shut off think yes defenetly 100% sure it is off, it happend again a while ago and i thoght the same thing may be it si deep asleep even i had chacked the weather 10 min ago and call myself from a friends phone and the operator said that the phone is off or i am somewhere without network covarage.
i got same problem. it turn off it selft and black screen even battery still 70%. rmust remove the battery to restart again, ealy bad. huft

If you have to remove the battery to get it to restart then its not actually shut off, its just stuck in deep sleep! which is usually caused by a bad app.
Yes if you have to remove the battery the problem is different, i just have to push the power button and it boots right away after it have shuted off by its self........
i didnt have this issue with my 855. but i did a factory reset after i got the phone just for the hell of it
So it's reset time i finally have some time to the some staff on the phone so hopefully everything will be fine. I will post if this fix or not the problem to inform the other people in this thread.

did you have any luck with the problem? I have the same issue, performed a factory reset and restored, hopefully it will fix too..
Hi all!
I have and have had the same problem and think I've pinpointed the problem to Google Search but can't 100% confirm it yet. I didn't do a factory reset when I got the phone and it shutdown during the night. I did a factory reset, made sure it got enough time to update everything properly. Problem was gone and worked fine. HOWEVER, the phone kept asking me which home screen I prefer at random times when I hit the home button. With random I mean like 4+ times per day. I searched the net and found a threat saying that a guy with a G2 solved the problem by removing Google Search updates. So I decided to do just that and get the factory version back and the questions disappeared but guess what, the phone shut down the following night.
Any takers or might this just be random? Note that it was working fine for three days with the updated Google Search and shutdown the first night after the downgrade.
So I did hard reset and so far so good the phone had not shutted down itself, and I updated everything which need to be updated (mentioning this for the guy with the upper post). So far so good I will keep you in touch if something goes bad...

The problem will be resolved?
I suggest take it to your dealer and get it replaced asap. I've seen lots of returned phones(my job at XXXXXXX company ) with the same issue, and as long as the defect is reproducible the dealer will give you a new phone. If it's outa replacement period then they'll probably repair it.
aaaaaaaaaaaaaaaaaaaaand shut down again but this time it took quite a bit time longer to shut off by its self so i tought the problem was fixed, but it's not, so i am going to the store which i buy it from to replace the device.....
Does this also happen with the korean models?

Random Reboots?

I was just wondering if anyone else has an issue with their Note 4 rebooting randomly with no external input. This started happening with the Android 6.0 update both on the download from here and the AT&T official release, Any Ideas? I've already purchased a new battery due to a separate issue, any idea?
I had the same problem. The phone would freeze and randomly reboot. Sometimes the system crashes and asked me for the typed-in password (not fingerprint). Sometimes when I charge the phone, and unplug the power cable, the charging led stays lit and the battery has to be pulled. I decided to switch the battery with my wife's Note 4 and see if the effects remained. So far I haven't had any problems after switching the battery, so I believe the battery may be the cause of all these issues. I'll keep you updated on the issues.
I'm back. The battery replacement didn't fix the reboots. I think my phone's hardware is permanently damaged. :crying:

its something completely different to this topic
I've been having the same issue, started about 2 weeks ago. phone would start being sluggish then if I continue tapping on screen, it'll reboot. At least once I saw it go into recovery & reinstall firmware(?). Another time it just sat at the bootloader screen waiting for software download or something till I took out the battery. Most likely it's a software issue related to 6.0 update or updates afterwards. taking out the SD card helped a bit.
but basically got annoyed & upgraded to LG V20 today. Coincidentally, there was another person at the AT&T store with a Note 4 having the same issue.
Mine just rebooted twice on me a while ago, first is emergency calls only now the reboots then what. And yes the slow charging is a problem too. MM got serious issue dam att

use wakelock its an app u get it from play store.it makes ur cpu always running.some how it fixes the problem of random reboots. dl it and set it to partial lock (the 5th option)
Same problem. Just started a few weeks ago. REALLY frustrating having to enter my password every 3-4 minutes. NEVER buying another Samsung, too many damn issues with this phone.
My reboots tend to happen once the phone goes below 60% battery. It's fine above 60%. Once it goes below 50%, the reboots tend to happen with any intense network activity. The phone will often go from 50% to 22%. I forgot what the 30's and 40's look like. I will try the Wakelock app.
Ugh. I posted about this a few weeks ago. It's started happening more frequently and will occasionally go into a boot loop or show 0% battery even though there's a charge.
Has anyone found any solution? I haven't tried wiping / resetting but I'm getting close to trying it.
Here is a cautionary tale for you. My completely stock, unroooted phone started acting the same exact way. On the 4th or 5th battery pull (to fix a frozen screen) it just crapped out. It's totally unresponsive. Deader than a door nail. Tried everything. The download mode, discharging by power button depression/battery removal, etc. Adb shell command does not detect it. Nor Odin. Computer throws up a qhsusb_bulk error when I plug it into pc. I have NO CLUE how to fix it & I am desperately seeking a solution. Please proceed wisely with your oddly acting phones & don't let this happen to you.

Same issue. Just got off the phone with Samsung support, all possibility of having this particular phone with this particular issue sent in for evaluation has been suspended. Translation, they know it is an issue and will not stand by the changes they push to their products (latest OS). I am researching the prospect of legal action since THEY pushed the new OS against my request. Shouldn't that affect the warranty or coverage? Consulting my attorney friends as we speak. Will let you know. I am not sure how WakeLock will help, it is not going to sleep, it is repeatedly power cycling through a kernel process until the battery overheats or it reboots.
Same issue
Since Marshmallow, my 910A will get sluggish or freeze, shut down, sometimes reboot and sometimes just brick (temporarily). Sometimes--more often in recent days, I get a "dll_mmc read fail" message and the target that says do not stop downloading. No matter what I've tried--factory and soft resets, cache clearing, battery pull, replacement, and SD card switch, contacting AT&T and Samsung rep--it doesn't seem to change. This is a daily issue and becoming more frequent. Any suggestions or do I just need a new phone? Thank you.

Lg g3 endless bootloop with new battery

Hi, my phone suffered from bootloop and according to the tremendous posts about this problem the answer was always laying in buying a new original battery, which i did but still the bootloop continues, may open for a few hours then bootlop again,
if anyone could help that would be appreciated because i'm giving on the phone now
mines doing the same thing with the original battery..
interested in the answer before i outlay for a v20.
---------- Post added at 11:24 PM ---------- Previous post was at 10:33 PM ----------
I had a bit of a hunt around and i noted that the phone has an issue with the WiFi.. so i disabled the WiFi and Bluetooth in the settings
as a precaution i ran some tape over the NFC and Qi battery charging connectors, blocking these connections.
if this solves the problems.. ill be outlaying for a new phone soon.. ill wait for the G6 to come out before considering the v20
ill post back in a week if i experience the same issues.
looks like this did not fix the issue.. i will try a custom ROM tonight to see if it fixes the issue..
i am wondering if the battery is the key here, it is possible that the software is seeing the battery voltage and when it drops below a certain volt the OS automatically shuts down the phone to protect itself..
as i only see the boot loop when i am launching particular heavy load apps. and i don't see this happening when the battery is at 100%

some interesting points here.
Do you have a reboot (phone restart) or a bootloop (phone try to restart but it never pass the boot screen)?
Have you noticed temperature issues?
If you have already tried return to stock and the problem continue it probably is a hardware failure.

before with the old battery it started to freeze and restart then it got worse, it closes and bunch of bootloops then open then 2 minutes and bootloop again, until it permanently bootlooped ,so i bought new original battery from lg store and the phone opened first time then 5 mins later it restarted then bootlooped once again, thing is, by the new battery it opens sits for an half an hour or less then bootloop, with the old battery it never passes the lg logo.

Hi , I have the exact same problem and i thought changing battery is the solution but i got my new battery today and everything was fine at the begining but later when the phone tried to update some apps again it turned off .
I had this issue suddenly few days ago after install some apps or some updates .. I am hoping it is because of software issues and can be fixed after factory reset.
(phone able to start when it is colder , so i tried to put it 2 min in freezer and it started but just tried one time , i dont know just coincidence )
I tried to update my firmware to 6.0 MM , so nothing change.
Looks like nobody able to solve this problem. Now my phone is just garbage

It is even better now because I opened up my phone and heatsinked the cpu .. I am still using lower cpu freq but even works without cpu adjustment after heat sink .. Now using 1.5 ghz just for incase.
(Still sometimes turning off itself when charging) Would be even better with heat sink pad i guess
I had heard that adding a 0.5mm thermal pad to the SOC makes its run a little cooler, but i do seem to think the battery is the main culprit, the main problem with getting a replacement battery which operates within the same tolerances.
downclocking the cpu to 2.0-2.2ghz with a fresh battery and adding a thermal pad on the SOC seems like the best solution..
I have since upgraded to a v20.. so hopefully it doesn't happen with that phone..
Some old original baterries have an issue that swollen a bit and the phone starts rebooting itself. But I don't remember from which year the good ones are manufactured.
Try testing with a generic battery (as I do) to see if that's the issue.
If you still have the battery's warranty, claim it.
I got a new battery, then charged it fully, then added an empty SD card to back up the data. Connected to a fast charger., otherwise it is not enough power to keep it on, causing a bootloop. The phone must be cool, not powered on for some time (overnight, in my situation).
I was able to back up the data., my main goal. I have heard others being able to fix it, and it works for some time, but soon enough this trick no longer works.

Note 2 keeps restarting everytime!

Hi guys. A relative asked me if i can repair his note 2. I think his network was locked and the phone keeps restarting everytime. I flashed a new firmware on the phone. The one I use on mine..XXUFNG1, and also I went into recovery and clear data and cache after flashing. But still the phone keeps rebooting everytime. Why is that and how can I fix this?
Note : It's not bootloop or anything. You can switch on the phone, use it for like 5mins and then it freezes and restarts itself. And it goes on like that. Sometimes it doesn't restart also and you can use for more. But most of the time after 5mins, it restarts.

Hi..thanks for reply. I tried another battery in it. The one I use myself. But it still restarts. I don't know if the phone was dropped or anything though. The relative just told me that it needs to be unlocked. Do you think it's software related? Or something is damaged in the phone?
Since it is running a stock ROM and still behaves this way after a factory reset, I think there is a hardware problem.
I might have a similar problem. I copy from another thread:
Hey guys,
I like this rom so far. But since 2 weeks I got an issue.
My phone randomly turns off, atleast I guess that's what happens. Sometimes the "notify" LED is on permanently but the display won't go on. To start the phone again I have to put out the battery and put it back in.
My battery is randomly empty pretty fast even if I just let the phone turned off. This happens like every 5 minutes.
I already bought a new battery but the problem hasn't changed.
What to do now? :>

I like the phone. It's over 5 years old and runs like the first day. Except it DOESN'T wake up anymore after a short time when the screen is off. I can press the power/home button as many times as I want and wait for 5 minutes, screen will still be off. Only way to "wake" it up again is to put the battery out and in again.
Currently I don't have enough money to buy a new phone and I can get a new motherboard for 25$. But I'm not sure if this will fix my problem.
I'm not even sure if this is the ROMs problem since it worked with all earlier versions of this rom perfectly and even the latest release worked for weeks/months.
Click to expand...

As long as I leave the screen turned on the display/phone won't go off and I can use it as always. Even the battery don't drop drastically then.
It might be exposed to moisture tho. When I take a hot shower I'll leave it on the window sill and the room gets steamy.
ROM: [7.1.2 r24] LineageOS for N7100 [Unofficial] - Version from 08.10.2017
GAPPS: Open Gapps ARM 7.1 Aroma - 03.05.2017
Baseband: N7100XXUFND3
Ril and other stuff I don't know where to check.
Some years ago I had the SDS and the motherboard was changed without the EMMC bug.
Sometimes my phone only charges in slow mode too.
I try a clean install and newer pico gapps now. Maybe it will solve the problem. I'll reply then if it worked or not.
[EDIT]
Since my phone was low on battery I turned it off completly and put it on the charger. After an hour or so I wanted to look after it.
The green charging light stays on and if I want to turn the phone on nothing happens. The light stays on even after removing the charger.
Seems like a hardware, not a rom problem? Will changing the motherboard fix this?
[EDIT 2]
Quick update. I fully wiped/factory resetted and clean installed newest version of this ROM + newest mini pico GApps. Still the same problem. Gonna try it with another ROM/kernel now and if the problem persists it's a hardware fault.
[EDIT 3]
Fully wiped again and changed ROM+Kernel. Still the same problem.

Device stuck in loop.. "Mi Logo" then battery icon.. this keeps repeating.

Friends,
My redmi note 5 pro was 50% battery and it suddenly turned off. After that when power connected no response. Connect via USB and Mi Logo appears first, then the battery icon with a flash symbol in middle. This repeats continuously. Some help, please ?
The phone is not rooted. Still in warranty period. No recent update. The last update was 1 month ago. No glitches after that.

Seems like your battery is dead, try charging it for some hours.
Any solution. I'm also having the same issue.

Woh.. its been a long time, though I am still using the same phone. ?
Try a hard reset first, if it doesn't help run to the service center. Don't worry about your data, service technician can easily recover it.
Back then My phone came into contact with sweat moisture and it fried few chips on the mother board.
Fluid damage is not covered under warranty, yet they gave me 50% discount. ?
All the data was restored afterwards and the phone still working fine.?
Hope you will find a solution soon. ?
Hey, it might be a bit late but i found a solution: i charged my phone for a few hours in fastboot mode (volume down + power button). Then turn it off and on again.

Same issue here. Any help will be greatly appreciated!
I was also facing the similar issue yesterday. Actually my phone fell down while charging after that it's started behaving like that and I kept on charging for 2 hours and tried to switch to fastboot mode still no luck and after that I left the phone idle for sometime witout charging and I gently pressed all the edges of my phone and tried fastboot mode and it's started working.
I know the solution which I gave looks silly but it's worked for me
