All,
See that the new AT&T update for the 850 G3 came out...I'm currently rooted via towelroot and nothing else. Tried downloading the update, rebooted, installing process and failed. Said I was rooted. Booted me back to normal. Anyway to unroot myself without wiping everything?
Nope, you pretty much have to flash back to stock via the top file which will wipe EVERYTHING including the internal storage. The better question is why do you want the att update. If you are absolutely desperate you can try the root cloak xposed module, that may or may not trick the updater into attempts to flash but may also brick your phone.
I just tried this and it didn't work. I the below method last night but the LG Flash Tool keeps failing and giving me the error "cannot change to download mode". I saw there were some issues when using Windows 8 so I"m going to try and put Windows 7 on my old laptop and try again. If not I will try another computer with Windows 7 already installed.

Just took my device out of the box today and it kept bootlooping through the intial setup. I finally got it setup and it's still randomly rebooting. I've factory wiped, updated to the latest rom version OTA, reflashed that rom manually. If the phone is in recovery or bootloader the device doesn't reboot. So it's got to be a software thing I feel... Anybody else seen this before? Keep in mind it was bootlooping even before I got my google account setup so it's not software loaded to the phone.

Don't bother with troubleshooting. Bootlooping on the FIRST boot is never a good sign. Return for a new device. Storage could be corrupted or something strangely particular like that.
Galaxy s8 on Verizon, a standard update notice kept appearing past few days, finally installed it. The minute it finished, it is now in an endless restarting loop. The phone does unlock and show my homescreen. I can get into it, but I only get about 10 seconds to do stuff then it freezes/restarts. Tried Clear Partition Cache in the recovery mode. Tried Safe Mode. No luck.
When I rush over to Settings>Software Update, and click it, it says "Software update in progress"....so it makes me think it is the remnants of the new software update completing itself, and that causes the rebooting. The final stages perhaps? Is there a way to CEASE that the second I unlock my phone? To stop all the background stuff.
Or maybe wouldnt make a difference. Any ideas besides factory reset? Way to revert back?
Wanted to backup a few recent pictures first.
A factory reset is the last resort to fix this.
Maybe it's theme related. Try toggling the button layout (settings -> display -> navigation bar) a couple of times.
If you have substratum installed, try disabling it.
If you want to back up your pictures;
Have you tried accessing the phone using a computer? Either just through a file explorer or by using ADB? To use ADB, you may need to get into settings -developer mode
I tried plugging into a computer, but I only have about 10 seconds, so I dont get enough time to access the files. I get into the phone drive on windows Samsung Galaxy>DCIM> CAMERA> ...then it reboots.
Developer mode is already enabled. Can ADB be used while on the recovery mode screen? I can access that command line looking screen as long as needed.
But accessing the phone normally like turning it on and unlocking the screen would not work, I would keep losing the connection when it reboots.

Try downloading that same version of Odin flashable stock firmware from the internet, the same version as the update that you received, then flash that via Odin. As long as the update does not upgrade your bootloader or your binary, it will not wipe your user data(pics).
But first....
If you can get to the homescreen and unlock the device, don't touch anything else once the device opens, just connect it to PC and retrieve your photos from the internal storage, then factory reset the device.

I dont know what version the update was that caused it or how I would find out. But I ended up getting it fixed.
I just downloaded the most recent version firmware from SamFW.com, and used that one. The First flash, the phone was worse! It was now stuck at the samsung logo looping. I flashed it a second time, then it worked! Phone back to normal and backed up my pictures. I had used the home CSC file too, and none of my user data was wiped. I thought it was supposed to wipe that, got lucky
I assume once that OTA update comes back and tries to install, I may have this problem all over again. I can't go forever without the security updates.

I had tried that a couple times, it lasts about 15 seconds then restarts. Not enough time, I would get to the DCIM folder but before pics loaded, it froze and restarted.

The most recent version that you downloaded might be the same update. The OTA updates and the Odin flashable updates are the same thing, the OTA update is just more automated. Flashing the same version as the OTA update via Odin, yields the same results. I think the Home CSC is the one that doesn't wipe user data. I think the Home CSC is intended for users that intend on keeping the device and using it in the same region/network and the other CSC is intended for users that want to sell the device or use the device in a different region or if you have a custom ROM and custom recovery on the device and you want to restore to stock. I could be wrong though.
If you do get a prompt for an OTA update, backup your data then factory reset the device then allow the device to update. That should prevent any further issues with updating via OTA.

Okay, I see.
Well when the phone did boot back up normally after the 2nd flash, there was a pop up that said software update unsuccessful. So I'm not sure if the same OTA update actually updated per se. But yeah, next time Im ready, I've got everything backed up!
Thanks so much!

I always prefer updating via Odin instead of OTA, it is much better and less chance of issues such as bootloop or random reboot. These are the issues you were having. I actually suggest using Odin or Smart Switch on PC the next time an update is available. Or, on older devices, use Odin or Samsung Kies to update. OTA is frequently unreliable, it commonly causes bugs, especially if the update is a newer android version than what is already on the device, it usually causes conflicts due to user data from your previous system apps and user settings conflicting with the new system because of differences between the older system apps and the newer system apps or differences in settings in the older system conflicting with changes in how the newer system settings are handled. Systems don't like using system data that was created by another system when there are differences between the two systems.
Another method that can be used is if your manufacturer/carrier releases a stock update.zip that can be flashed via stock recovery, they are made specifically for flashing via stock recovery ONLY, they are not the same as the stock firmware file that is flashed via Odin. These can be downloaded to the phone's internal/external memory then you boot into stock recovery then factory reset/wipe cache in recovery(backup data before wiping) then you can flash the update.zip. Alternatively, you can flash the update.zip without resetting/wiping(this is called a "dirty" flash), in theory, a dirty flash is useful when you don't want to wipe data or lose data. But that comes with a chance of causing bugs, as you have discovered for yourself during your update process.

KB2007 Tmob 8T+5G
Rooted unlocked all has been well.
For the last couple of OTA I have uninstalled Magisk to restore the boot partitions and taken OTA without issue
Root once more all is well
With this latest OTA11.0.8.10.KB09CB I uninstalled Magisk
but fail on the OTA
Couldn't update installation problems
Fails immediately I don't believe it performs a download
Any thoughts?

***********************************
Deleting what I considered bloatware(Native Oneplus apps) was the cause of the issue.
My solution was to perform a full restore using MSM recovery tool.
No issues taking OTA thereafter
Exactly the same problem, I wonder if it's related to the fact that it's rooted or it's universal
Well i unrooted and could not take teh update.
im thinking of switching to another regional ROM to get updates and apply them myself
When you were rooted did you uninstall some bloatware (like Chrome, community app etc...)?
I just completed a restore via the MSM tool.
Most awesome app.
Looking at all the bloatware I am quite sure I removed apps.
Which is a good reason to be the cause of the issues.
For years I've been doing OTA updates and using Magsik, patching the boot image, etc. I'd like to think I halfway know what I'm doing. Every so often because Oneplus keeps changing the way their damn updates work the OTA fails, bootloops a couple times, and I just switch the active slot back to the working one and try again. Well this time updating from the OOS 13 December update from the original October OOS 13 update, I got the bootloops, switched the active slot, and when it booted up all my data was gone. No warning, no prompt. I did NOT tap wipe data or anything in recovery.
Did something change yet again? Is the software really going to wipe data without warning just from a failed boot?? I'm blown away.
So I guess be careful doing OOS 13 updates. God forbid you make a mistake and it'll wipe your data...
For years you've been learned the purpose of backup...
