Hello XDA community,
I would never post on here unless it was a last resort. I tried everything with this phone to have it rooted. I rooted successfully in Android 10, 11 all of them worked, but all of them failed over the same issue after a few days which ill describe below. On TWRP + Stock Root Rom, the logs read something about "android telephony". This time around the logs (Adb logcat) is huge and I can't find what causes the bootloop. I am sure it could be fixed somehow.
I Installed Lineage OS 18.1 successfully. In all root roms (phone is dual sim) and even in normal rom, after 2-3 weeks the phone will crash and enter into bootloop. On LIneage OS 18.1 it started after 2-3 days.
Strangely this seems to be related to using express VPN (not sure why). Pressing reconnect on this software causes always the first bootloop. From there on phone repeats the bootloop every time it's rebooted, non stop. It restarts itself and bootloops again.
I have tried installing every rom there is available including root official rom. Nothing fixed this problem.
I am to where i will definitely provide financial compensation if anyone can really help me find out what this is and stop it. I cannot send the phone to OnePlus as they will not provide help over these matters.
I Need liberty of root user without all the harassment of the bootloop.
Now the phone is at LineageOS recovery and lineageOS 18.1 build. It WORKS in safemode, but it bootloops only in normal mode. There is nothing I know to do to stop it.
So I have access to every other function except the normal use of the phone.
Please advise.
It's one of the apps running in normal mode. Seek and destroy... obviously it runs at start up, that should help narrow it down.
Thanks for the help, but I have attempted this to no avail. I have removed all user apps but still the issue persists.
This has also happened on every rom I installed, after about a few days or weeks.
Could it be some remote command is used to terminate the handset? How can I diagnose what is happening?
What if you reflash without Google apps?

I have tried, it was without Google Apps to begin with.
I am going to repeat same process and see if the next one bootloops too.
The strange bug occur when VPN connection was activated/deactivated. AFwall was also enabled, running as admin. Then this persist even when I uninstall all apps through safemode ADB.

Hi,
I am reading from time to time here at xda about random reboots issue with ZUK Z1, so here is my short story.
I am the user of ZUK Z1 since last year at the time there was only COS12.1 and CM12.1 available. The phone was working great for the first few months, no single random reboot, even with heavy usage and tons of root tools like xposed framework, greenify (with exp. mode), amplify and other experimental tools etc. Rock solid stability, CM12.1, ZUI, COS12.1, no matter which one.
Some day, somewhere beetween feb/march this year I started to see occasional random reboots, sometimes once a week and sometimes three times a day. After the last one of this random reboots, the phone refused to boot. No recovery mode, no charging screen, no fastboot, even no access to qualcom recovery port for use with QPST and QFIL tools.
Tried to drain the battery and charge again with no success, tried to soft-restart by power button - no success. The thing that helped after phone sitting on desk for next three months, was to dissassembly the phone and reconnect battery. After this, the phone boots up again, bot the random reboot issue is back, no matter CM12.1, CM13 or COS12.1
And now the questions time:
The question is, is this a software issue after some of the updates or hardware issue?
Are there users with the random reboots problem with the newest firmware?
How to debug and catch this random reboot on the logs without ADB connected to see what is going on?
What have i done to fix the issue:
- reflash phone many times with different versions of COS12.1 and CM13
- flash fresh .zip from recovery
- flash directly from fastboot with official COS images the support page
- fsck, partirion check for errors, etc.
- formated phone by QFIL tools
- tried to track the problem from logs, but so far no value information are stored after reboot
What i am going to do:
- install ZUI 1.6 to verify that the issue comes back
- as much as i can, use the device with ADB logcat connected by cable, to catch the occasional reboot
- recompile kernel with enabled options to store crash reason after reboot ( kernel pstore feature or last_kmsg )
I am in the same situation as you, investigating....
Please update your results, very interested to find if software or hardware problems....
Thank you.
Carlos
Are you restoring apps after you flash your phone? If so, try not to. Just install basic apps you need and see if problem persists, since Google restores app with it's data.
Phone rebooted in recovery, so I think it's a hardware problem.
Phone is traveling to China again.
After what perio of time your problems started? I have my z1 for 2 weeks and it works perfect. I keep it on heavy usage for a few hours daily.

Hello,
I'm in the same situation !
My phone randomly reboots and also freeze (have to do an hard reset).
Have you find any solution ?
I am also having this issue... I will probably send it for the warranty. I have tried a few different roms, even restored back to CyanogenOS and the reboots continued...
I got mine since October, haven't had any reboots so far.
I'm running the latest update from cos without root or custom rom.
Seems like a hardware issue to me, I have tried everything software side.
same issue
I'm also having the same issue,any fixes??
Random reboots just stopped happening on my device a week ago. Before that I was trying different ROMs and flashed different versions of TWRP but the reboots were still happening. Then the reboots just stopped from happening and now everything is working perfect. I think it is a hardware fault. Probably some electronics (cables or what not) on my device are now having contact but were not having it before, I don't know. But if you are experiencing rebooting issues, just send your phone to the repair.
Any fix to this?
Whenever I do dirty flash, my zuk z1 random reboot twice a week. It is highly recommended to do a clean flash if you want to avoid random reboot.
Clean flash = No random reboots. @sebeqone
Hello people of the world,
after reading a lot of posts here I still can't fix my phone's issues, so I need to post. Bear with me...
I have an N910F which was entirely stock and functioning without problems. Two days ago I accepted the official update. After that, the phone regularly lost connection to the mobile net, froze, and restarted. It would work for a short while until it froze and restarted again and again. When I tried to use the camera, the live picture was completely distorted. The phone crashed and has then gone into a bootloop.
I pulled the battery, did a recovery start and wiped the cache. No difference. Factory recovery next, no difference.
I have since tried several stock and custom firmwares, always taking care to follow instructions and use the correct bootloaders, modems, etc. TWRP is working.
When I flash a stock firmware, it will go into a bootloop. With any custom ROM, it will crash during startup (logo) and switch off.
Any help would be greatly appreciated!
Protect the eMMC?
So, after more reading I began to suspect that the eMMC had moved on to the valhalla of electronics. Sent my phone to service where my suspicion was confirmed. Luckily, they were able to replace the chip without having to put in a new board.
Is there any way to prevent this kind of failure again, or at least make it less likely?
Yes this is a known issue after latest update you could you install only one application called wakelock so that your phone doesn't reboot and CPU keeps awake

Thanks! I had read about that.
Got my phone back from service today, they had flashed stock 5.0.1. After checking that it worked I flashed RR 5.8.4 and installed Wake Lock Powermanager. I searched for a comprehensive tutorial on what the settings do and which to use. Right now I set it to PARTIAL_WAKE_LOCK (4) but I'd like to read more about it. Any tips on that?

installing power wakelock and setting up on partial wake lock is enough.if you get trouble in starting your phone remove its battery and put your phone in refrigerator for five min.and try to start your phone.this problem also related and happens after the latest update
Hello everybody,
To introduce my problem, I explain the situation. I buy a V20 H990DS that I tried to root but with no succes. In my trial, I do some many fatal error like erase boot and aboot partitions.
I send my phone to after sales services and they repair my phone. They changed the motherboard and now, I'm with a v20 H990N.
The first startup, i get some many application don't work and literrally crash like gallery, camera etc... I do a factory reset and upgrade the firmware with LG BRIGDE to Oreo. Everything passed good and I start use the phone (no apps installed, just testing). But, some app start crashed but less frequently.
So, I decided to root and tried another stock firmwares. But each times, I have some app crashed. My last crash, in the configuration start step, is about the EULA app and crash at the end of configuration which has the effect to restart the start configuration and you can never finish the configuration.
I tried different kernel, too, like mk2000 or DOTS but same thing.
I tried different custom rom, too, like resurrection or lineage (for h990ds) but each time, I have errors during installing zip in TWRP.
Actually, I'm in TWRP 3.2.3 like recovery, DOTS like kernel and I will try the latest Oreo zip root flash.
Have you encountered this kind of problem too ?
Thanks for help !
Hey,
I have been using the ColtOS rom based on Oreo 8.1.0 for quite sometime now. I had it rooted with Magisk too. I have the latest version of TWRP installed (version 3.3.0). I had no problem until now where it just randomly tried to reboot after I ended a call. It did reboot fine once, but it was when i ended a second call that it got stuck in a bootloop.
I have tried everything, clearing the cache/Dalvik , wipe data and system and flashed three different Oreo ROMs, uninstalling Magisk. However, I can only go as far as the set-up screen after the new ROM boots, after which it goes back to rebooting itself endlessly.
I seem to have exhausted all my options, any kind of help to restore my phone will be greatly appreciated.
Thank you.
I have found out that I can flash new ROM and even set up the phone by logging into Google, only when I connect my phone to my laptop. It even installs all the previous apps and data and thats it. It reboots to the lockscreen and when I try to unlock it, it reboots again. And this is all only when I keep the phone connected to my laptop, otherwise,it keeps looping into the bootscreen logo.

So I've finally got to upgrade from A10 to A11. I was unable to follow the guides for doing local upgrades, because of my previously mentioned "No changelog" and "System Update Installation Failed" message the moment you selected the upgrade package. I tried multiple downloads and verified hashes, this wasn't a corrupted download. So I ended up having to Wipe data to get to a stock A10 and then upgrade using local upgrade. That was Sunday. Since then, I've rooted, restored my apps, lived happily on A11....for about 1-2days before I'd wake up a bootloop. The phone would just be sitting on the spinning Oneplus logo without me knowing why we got here. Even stranger, I had NoLimits installed, so I should be seeing that instead of Oneplus.
Attempting to fastboot boot any of my boot images still keeps me in a boot loop, not much to do other than to wipe and try again....So wipe, on A11 stock, root, restore apps and go on my way....Worked great yesterday. again all apps were restored, things were working, no issues. And then I woke up this morning to find issues with Facebook app (images not loading). Okay, whatever, something may be corrupt, just wait for an update from them. Multiple apps in Playstore need an update, great...do those. But then Oneplus Gallery refuses to update...hmmm. Catlog/Logcat refuse to open with insta-crashes. Facebook nolonger has the corrupt image issue, it just insta-crashes.......uh oh......maybe a reboot?.....rebooted and then stuck on NoLimits bootscreen for about 2 minutes....after 2 minutes it reboots and I'm back to being stuck on Oneplus boot image.
So I'm out of ideas now. about to wipe and go back to A10, because I can't for the life of me find a connection to all of this and its getting tedious to restore apps (especially 2fa apps).
Any help would be appreciated.
Hi!
I have had annoying bootloops when making a call.
It connects to a call and then boom, goes dark and reboots by its self. Very annoying.
I have 2 SIM cards on use, dont know If that matters.
Iam suspecting the network connection change during call -setting has something to do with it...
Hope there is an update coming soon to fix this.
Yea I have 2 sims as well (TMo and GoogleFi) so that's an interesting point. We finally now have dual-sim (US/Glo).
I'm currently testing out how long i can go with my current setup: Just A11 + Root + NoLimits....wait about 2-3days, then try LuckyPatcher (best way I know to remove ads), 2-3days, and then continue testing other ideas).
