Device rebooting over and over - AT&T Samsung Galaxy Note 4

I was checking my phone to see if there was a way to Sim unlock the phone from the service menu and once I didn't find the menu needed I was about to exit the service menu. As I was exiting the service menu I believe I turned something on or off not. Now my phone Note 4 AT&T reboots over and over. Any ideas what could have change or what I need to do to correct the issue?
Thanks

Well, pull the battery put it back in and hold volume up, power and the home button, once the screen comes on release the power button only. Use the volume keys to navigate and go to clear cache and hit power once, let it do its thing and than reboot the phone. If that doesn't work follow the above instructions and instead of clear cache do a factory reset.

Tried both wiping cache and factory reset. After factory reset, the phone tries to apply the android updates but doesn't finish as the rebooting is still occurring.

If it's under warranty take it back and get a new one.

I tried turning on art and it kept rebooting but that's not what you did. Anyways maybe try flashing a the stock firmware through odin? Or down kies and there may be a repair mode

Crashing after 5.0.1 update?

I just updated via the update in settings to 5.0.1, and now my phone keeps crashing after 1-2 minutes. Even when there isn't any apps open and its on idle, it keeps crashing. I've tried to restart it, close all apps, and turn it off for a few minutes, and nothing seems to work. Has anyone else had this happen?
Do a factory reset.

It crashes before it shuts off to reset. I'm going to take it in to best buy tomorrow and have them look at it
There is a key Combo you can use to go into the recovery mode and do a factory reset from there. That is all Best buy will do. I think it is hold both volume keys down while holding the power button then let go when it starts and it will start in recovery then do the reset from there. Mine did the update fine with no issues so far. Hopefully it stays that way.
Power unit off and try to boot in safe mode by holding down volume down and then hold down the power button. When it starts to boot, release the power button while still holding the volume down. Once it boots up then try a reset.

910V stuck on bootloop

I have a 910V which stuck in bootloop, I flashed the stock 6.0.1, 5.1 firmware, using Odin, both of them loaded fine, so far I haven't seen any EMMC error or any other errors using Odin, I can go into recovery and I can do factory reset, but as soon it goes past Samsung logo it restart again. I swap batteries, there is no Sim, SD card in it, I don't have EFS backup. I also tried this N910VVRU2BOG5_VZW2BOG5_Verizon_USA_v5.0.1_Repair_Firmware still no go.
I am having the same issue, stock verizon, never rooted, no new apps installed / no reasons for boot loop... itll go as far as the verizon logo then immediately restart over and over again
using ODIN v3.12.3, I tried the following, all loaded none fixed the problem:
N910VVRU2CQI2_N910VVZW2CQI2_N910VVRU2CQI2_HOME.tar
N910VVRU2CPF3_N910VVZW2CPF3_N910VVRU2CPF3_HOME.tar
N910VVRU1BOAF_N910VVZW1BOAF_N910VVRU1BOAF_HOME.tar
N910VVRU2BPA1_N910VVZW2BPA1_N910VVRU2BPA1_HOME.tar
in odin I uncheck the restart in the options tab
then start...
once done I turn phone off completely. Start phone with Power Button, Home Button, Volume +, then itll say installing then go to the menu -> Select in this menu "Wipe Cache Partition", then factory reset wipe, then I pull the battery and turn on. goes to boot loop every time...
then i tried this : https://forum.xda-developers.com/note-4-verizon/help/verizon-note-4-flash-odin-t3470166 POST #4 - still didnt work
tried many many things just gets to the verizon logo and restarts...
using odin to flash firmware only - dont know if anything else will help. open to suggestions...
Maybe you could try booting in safe mode.:
Put the phone in download mode.
Once in download mode, hold all buttons at once and keep holding them (power, volume up+down, and home). It will take you to a menu, one of the options is safe mode.
Once in safe mode you can install apps using adb install. If you can do that, then you can run the apps by starting their main activity.

Phone freezes then acts like it restarted

Mostly happens through the night while charging but happened today while using it. This began after updated to June stock update. Is this happening to anyone else?

Just wipe the phone and reinstall a stock image from Google. If (for some insane reason) you haven't unlocked your bootloader, do a factory reset (you will lose all your data) and it'll work like brand new again. To do a factory reset, power off your phone and hold in the volume down + power buttons until the bootloader screen appears. Using your volume up and down buttons, choose Recovery from the list of options and click the power button. On recovery screen with broken android, hold down the Volume Down key, and while holding it down, click the Power Button. You have to try this a few times to get it to work, but it will unlock a menu of options, one of them being to do a factory reset, wiping system data and userdata and the cache.
Yes my bootloader is unlocked and I'm rooted using Magisk. I was wanting to avoid wiping everything bc it's a pain to set things up again. Is there a way to run a logcat and figure out what is causing it to crash? Not sure if that is possible seeing that it happens so randomly. It all started when I flashed an ota with twrp...I usually don't update that way so I'm guessing something went wrong with that. I have since updated again using the full system image and removing the -w from flash.bat but still getting the same problem.
Thanks for responding.

Verizon LG G8 Startup issues

About a month ago I shut my G8 down overnight while I charged it. The next morning when I pushed the power button to to turn it back on it would not turn on. I kept pushing the power button trying to get it to power up. After about 10 minutes of no luck my wife found info on line to hold the volume down and power button to force it to boot up. I did that and it started back up, but like an idiot I did a power down and restart to see if the phone fixed it's self, which it did not so I had to do the volume down & power button to get it to boot back up. A few week later when I forgot about the start up issue I powered down the phone and when I went to boot it back up it would not work with out doing the volume down & power button. So I started looking online for other people with the same issues and one forum I read suggested to get in to the recovery menu and wipe the cache. When I did that I got a screen saying error with an image of an android laying down, then the phone booted up. the only operation issue I have notice with the phone is it seem like the battery is draining a little faster since this issue started. I had the same startup and cache wipe issue when I tried it today. I am running stock software (G820UM10h) with October 2019 security software, Phone is not rooted. Does any one have any idea of what it is doing?

Go to settings, search backup, use the LG backup. Then connect to computer with file transfer (which should be automatic) then navigate to the LG BACKUP folder and move the file in it to your desktop. After resetting, move it back in to the LG BACKUP folder and restore from settings. I know it sounds complicated, but it really isn't; you only have to click like 4 buttons

Question Please Help me ever since the update!!! SM-F926U1 XAA

Since the update my galaxy z fold 3 doesn't play sound full screen or I cant hear anything out of my speakers unless I fold the phone anyone know how to fix this I installed the Software again and it didn't work I'm completely clueless on this factory reset it and nothing I know its a software error also when i open the phone the screen sometimes is just pure black any ideas or suggestions id greatly apricate it
Try this:
Clean cache in recovery mode​To clean the cache in Recovery mode, follow the steps below:
Power OFF the phone
Press at the same time Volume up + power button
release the volume button when your Samsung Galaxy Z Fold3 vibrates
Navigate with the volume buttons, find Wipe Cache Partition , confirm with the power button
Choose Yes
Then find Reboot system now
This is where you can do a factory reset as well (Wipe Data). However, I would start with wiping the Cache (twice) and see how things work. Last resort, Wipe Data and reset, but be sure to back everything up!
^ Try that suggestion first. It's meant to reset everything so the phone starts fresh, like out of the box.
If that doesn't work, reach out to Sammy/your carrier about the warranty.
