Previously I had a problem with my Moto Z randomly rebooting and some functions like battery stats or WiFi not working. After some time almost all these issues disappeared(I don't know why), except WiFi which still doesn't find any networks. I tried booting into safe mode, wiping cache partition and factory reset, but nothing helped. I'm running android 7.0. Is there any way to install previous software version/completely reinstall current one without voiding the warranty? I think this might help in this case - otherwise it must be hardware issue and I have to send my phone to repair anyway.

Hi, I'm having a curious problem with my S3 and I've been unable to solve it. I watched the "noob" video and tried searching these forums as well as a google search with various combinations of the wording for my problem. Nothing matching my issue turned up, I hope I didn't miss anything.
I recently bought a S3 second hand (yes, i know, i should have known better). It was rooted and running some kind of custom ROM when I first turned it on, but I was willing to deal with it until I double checked the procedure for getting it back to stock and starting again myself (nothing against the original rooting and flashing, just like to know exactly what I'm running).
When I purchased the phone I obviously checked that all of the main things worked - calling, texts, mobile data, wi-fi etc. I get home and connect to my home wi-fi and start checking things out and setting stuff up. The phone randomly rebooted. I carry on after the reboot and about 10 mins later, another restart.
To cut a long story short, there is something wrong with the wi-fi. If I turn off wi-fi in the settings menu and reboot, everything works great. No crashes, no reboots. If however I enable the wi-fi about 50% of the time it will crash while wi-fi is activating. The other 50% of the time, it will crash as it goes into the screen lock (either via timeout or pressing the button).
I've re-flashed to it's stock version of Android (using the 'Samsung GS3 Toolkit and Odin), same problem. Anyone got any ideas?
Thanks in advance
You can try updating the modem and RIL to the right version for your country, search in general forum. If it still reboots then try with another wifi source - I've seen some routers cause problems on client machines.
If you do a factory reset when you flash the modem, plus you have the latest stock ROM on board, then any remaining problems are probably hardware.
Test it fully after the factory reset, before you add any apps etc.

After much experimentation and flashing of various files to my phone I have further narrowed the problem. I've still not solved it, but getting closer I feel.
After a clean ROM flash it works like a charm regardless of how much i use the wifi etc. It's only after the first reboot that the trouble starts. It will begin randomly restarting. If I perform a factory reset from recovery mode, it works again, but starts resetting again after a reboot.
Any ideas?
So,
I bought this phone on the day it was launched, its been more than 3 months and had no issue with the device. I rooted the phone , experimented with Xposed and other apps but for the past few days i was experiencing this strange problem. Cellular network was not running on my phone, i changed the sim, swithed the devices on/off several times , did everything i could do in the os, changing the mode to 3G from LTE and vica versa, etc etc .. but still no luck. The cellular network sometimes comes and goes. Then i opted for last resort which was to factory reset the phone, after resetting it the cellular network worked but i don't know if this is a permanent solution. If you have anything to add please share.
Regards,
Saransh
Sorry nothing much to share but i suspect you install some apps or did something to your rom so the network screwed. My suggestion is you nandroid backup every week (at least) so you can revert back when something happened.
Tried factory reset
I have tried factory reset but still having this issue. Maybe it's a hardware issue. I don't get it , everything was working fine few days ago then all of a sudden this **** happened.

Maybe exposed screwed something. Get a microsd card with whatever rom you want in it. reboot to recover and try full format. insert the microsd after then flash a rom. see if it works
Rooted my phone with sudamod rom, Everything is working fine.
After my tablet is on for a few hours it makes a weird sound with any audio output. I thought it was a lollipop issue but after flashing marshmallow image the problem is still there. I'm on stock and unrooted. I've tried factory resetting after every update, clearing cache, deleting user data, etc...Not sure what to do next. I'm thinking about relocking the bootloader and contacting HTC before my warranty is up. You guys have any ideas what I should try? The only temporary fix I have is powering it off and on. thanks

I have the same issue and have found no fix for it thus far.
Tried Safe Mode?
Life is poker, risk being happy
Thanks for the suggestion, issue still happens in safe mode for me.
Contact HTC/Google it looks like hardware problem if its still apears in Safe Mode
Life is poker, risk being happy
In my case it happens in Marshmallow but flashed a week ago a 5.1.1 ROM and all seems ok. Anybody has a clue to fix it?
Hi everyone,
I have a moto E 1st gen with OS 5.1, suddenly one day it decided to not recognize the sim card and won't connect to Wifi either.
I took me some time but i could solve the problem, I did factory reset, I wiped the cache; it didn't work. I took it to service to get the simflex replaced, it didnt work, they checked other hardware parts, they couldn't solve it.
I did another factory reset in the meanwhile the phone began behaving weird;it would restart a lot and all apps began to crash.
I decided to go the hard way and flashed 4.4 through the computer.
Good news: SIM card and WIFI working again, yeiiiii!
bad news: OS boot, ask me for the language and a wifi and all the initial stuff; apps keeps on crashing a lot until the device reboots a minute after; and it ask me for the initial configurations again. and it does this again and again and again....
I checked on internet and all pages says that the app-crashing problem is usually a cache issue, the solutions are wiping cache or doing a factory reset; but I already had, several times.
someone told me the rebooting could be a power button issue, since the device had been opened a few times maybe the button got damage; but It won't explain why apps crash like crazy.
I'm out of ideas now, if you have an idea what could it be, comment below please and thanks.
Flash all partitions of your device with the factory images of your device, then wipe userdata partition and cache partition, dont forget that you need flash the 3 partitions of system sparce chunk, and erase the modemst1 and modemst2
I flashed manually; didnt use a flashfirmware.bat that I downloaded somewhere; and the phone is like new. thanks
Hi all,
Last night my phone started to randomly reboot itself, even in Safe Mode! It's now to the point where I can't even login -- I enter my pin, the 'Phone is starting' overlay shows for a while, and then it suddenly reboots. I haven't installed a new app for at least 2 weeks at this point, and the reboot was happening before I updated my apps. After updating, things seemed to get worse maybe?
Is there any way I can salvage my phone or do I have to hard factory reset via hardware buttons?
Its called bootloop. you need to flash your phone to fix this problem and flashing can fix all the software issues of your device.
I was afraid of that... Just a bit worrying that it happened randomly when running stock.
Ok, thanks!
I had same issue when ran android 9 in 2019, however, I fix this issue by doing a clean flash. Yes, you will lose everything, so make sure you do a backup via google.

If you didn't add an app or update that caused it either the boot load got corrupted or it's a hardware issue. The flash memory should not spontaneously get corrupted unless it's defective ie a hardware issue. However anything is possible... quantum physics.
More than likely it was a poorly written app or update that caused it. 3rd party launchers and power management apps are prime suspects. It may take a week or more to manifest its self as a boot loop. Any signs of system lagging or instability should be taken seriously as they are the only warnings you may get before a boot loop*.
A virus or rootkit** is another prime candidate.
Do a factory reset now. Be wary of which apps you load and avoid any updates until the system is know to be stable. Then add apps and updates one at a time. Updates many times aren't really needed.
Over a year ago I had 2 back to back boot loops on my Note 10+... yes, and 2 factory resets and full reloads.
The prime suspects were as I mentioned above. Neither one was reloaded after the 3red factory reset. A year latter that 3rd reload is still running fast and stable. Fun times
**if your Android version is 9 or above a factory reset will purge any virus or rootkit as long as you don't inadvertently reintroduce it. Be careful what apps you load and what you download.
If the Android version is 8 or below, they are suspectable to a nasty rootkit that requires a firmware reflash to purge. Pie and above are not.
1. For me, it was also itself rebooting, only while phone were in pocket / case. So do not use any of them (searched on reddit forum, was exactly same topic)
2. Maybe sim ejection tool is not correct be inside, don't often open and close it
