Removing Install System Update - E 2015 Q&A, Help & Troubleshooting

I'm getting Install System Update page / application appear on my device. I still haven't updated to 5.1 because I'm afraid it will break my tethering. How do I get rid of this screen? I'd prefer to do it from the phone and or through adb, since I don't have a windows computer handy.

I think somehow the update was forced. I kept it at bay for months. then one day, it seemed to update itself. Thought there was a method to block the System Update screen, but can't get any help here.

No data from WiFi or cell signal, might be SU problem

As the title says, I have no data from my home WiFi or 4G from the cell signal, despite them being shown as connected.
I noticed it just a few minutes ago. I was looking into Voodoo RootKeeper because I haven't updated to the latest OTA update and I've been wanting to soon, it was mentioned that SuperUser should be fully updated for it to work. While looking through SU settings, I noticed the option to set SU as a system app, so I did it. It rebooted and just before finishing the boot it had a message saying something about configuring apps (similar to what you would see after an update, I believe). Once it finished I was going to update some apps that needed updating and Play said it had no connection, checked Chrome and it was the same story. So here I am.
It is rooted, also has an unlocked bootloader (which is why I've waited so long to do the OTA). I haven't updated since I got it at the beginning of December last year, so the current version I'm running is 4.1.1
Any help is really extremely appreciated; my smartphone becomes a dumb phone without any networking, dumb phones make me sad :crying:
Edit: I fixed it, somehow. I temp-unrooted with Voodoo, tried to complete the OTA update (failed because of recovery or something), re-enabled root after update, and then I had data back. Leaving this post here in case someone comes across a similar problem.

[Q] Any way to not get Lollipop pushed OTA to stock unrooted S5 on KitKat 4.4.2?

Hi all,
I just got an S5 today and it has KitKat 4.4.2. I accidentally clicked on the "Software Update" button in the "Settings>About Device" page and it started downloading Lollipop OTA. I couldn't find any way to stop the download. I have no intention of upgrading to Lollipop any time soon, so now I'm stuck with nearly 1GB of wasted space and an annoying nag to update.
I've been looking through this forum and it seems like the only ways to get rid of the nag and clear out the downloaded update require a rooted device. I prefer not to root my device so I'm wondering if there's any way to get rid of the nag and the downloaded OTA update without rooting. Do I pretty much have to do a factory reset?
If factory reset is my only route, will the OTA update just get automatically pushed back out and downloaded to my phone in a few days or weeks? If so, there wouldn't seem to be much of a point in doing a factory reset if the update will just come back. Any ideas or advice would be greatly appreciated.
Regards,
John

In my case, disabling "Software updater" or something similar in Application Manager stopped the auto update (you can verify by tapping on "Software update" in settings again and nothing should happen).
Thanks for taking the time to respond. The post you linked was one of the articles that I looked at previously. The suggestions in the post seemed to only be applicable to rooted devices so I wasn't really able to use them. But thanks for linking it nonetheless.
In the Application Manager, I see two "System Update" applications. One can be turned off but other can't so I guess by default that that will be the one I'll stop. When I try to turn "Software Update" off, it gives me a nasty warning about stopping a system app and causing instability. Has turning off that application caused any instability on your device?
Also, all of these suggestions deal with how to prevent the OTA from downloading, but do you know of any way to get rid of the update and free up the space once it's already downloaded? I accidentally downloaded the OTA update and I'd like to remove it and have the phone not download it again. Will I have to do a master/factory reset in order to get rid of the update?
Thanks again for your help.
That nasty warning appears every time you try to disable ANY app, not just this one, and I've disabled a bunch of default bloatwares without any side effect. So you can just go ahead and disable it. As for the downloaded update, I would suggest using a file manager to list all files in the internal storage and sort by size, it would likely be the biggest file.
Thanks for the advice, Master 619. I tried using a file manager, as you suggested, but the file is not showing up. I'm pretty sure it's because my device isn't rooted and that file is in a protected area so I can't get to it. I'm figuring that I'm just going to have to do a master reset and then disable the "System Update" application.

Debloater Preventing Phone from OTA Update

Hello all, I'm having a slight problem, I noticed that AT&T keeps trying to roll-out a new software update, however, my Galaxy S6 Active will download it fine, and then when trying to install the update I get prompted with the message "The install cannot be completed".
I thought at first this must be due to an application that I had disabled, but unfortunately it was not the case as I enabled every blocked app, and yet I still got the same error.
8 files still remain disabled even though I tell Debloater to "unblock" all and they include the following (I have tried countless times to enable these files with no luck):
ContainerAgent2.apk
EmergencyLauncher.apk
KnoxBBCProvider.apk
KnoxKeyguard.apk
KnoxShortcuts.apk
KnoxSwitcher.apk
KnoxTrustAgent.apk
KnoxVerifier.apk
I even performed a hard factory data reset, and these apps still remained blocked. I just want to be able to receive OTA software updates. Any ideas on what I can do? Thanks.
Install the original firmware via Odin.

Losing root after every security update

I am having some issues with the G9 I am working with. I have root using the latest Magisk. But every time a "security update" installs and reboots the phone, I lose root. So I go back into fastboot and reflash the boot img. That solves the problem. But it is a minor nuisance I am trying to workaround. I have tried searching for days, trying to figure out how to STOP system updates. I installed a root service disabler and disabled a few different services.
I still cannot seem to figure out what service is downloading updates. I have already gone into Developer Options and disabled automatic updates. And there was an update waiting that I kept paused. Last night I got the popup reminding me about it. And it was supposed to "remind me later". But instead installed it in the middle of the night.
I could care less about opinions on whether or not to allow updates. I would just like to know what service or file I need to cripple to get it to stop. I want to decide if or when something runs on my phone. Any ideas? Android 9.
And you will lose root after update, it's normal

If you are using a G9, not a G9 Pro, could you please link me to the stuff to root it?

G695U No longer working after the April 2020 Patch

Last week on Thursday, I allowed Verizon to install their Software Update 21 (April 2020.) It made it as far as the going through the optimizing apps and then was stuck in a boot loop. The phone would be usable for about a minute, then would freeze, and then reboot. If I clicked on the System Update option in settings, it would say that a system update was in progress. I chatted with Verizon, and they ended up telling me that the only way to stop the update was to do a factory reset, which I am doing everything I can not to do that as I don't want to lose my data.
I changed it into maximum power mode and it did stop the update for that time being and I was able to use the phone, texting, etc. This allowed me to at least connect the phone to my computer to backup all of the directories. After many reboots, on Friday it finally stopped doing the update and gave me an error which I think was 410. It thought it was updated, though did show as failed. When checking for updates, it said it was the current version. Twice I was able to get the phone to stop by freezing when going to the app and stopping some programs (sadly, I was not able to remember the exact combination that worked) which allowed me to use the phone like normal. All this while, I was uninstalling a large amount of the apps that I had installed hoping that would minimize whatever may have been causing the problem.
Went to each of the google and samsung apps, stopped, disable, and reverted them all back to factory defaults. Guess that was a bad idea, from then on I received an error as soon as the phone started which caused it to go directly into recovery mode. I chatted with samsung and they thought it might be a hardware issue. I still think it is related to their software update, so not a hardware issue.
By using Odin, I loaded the firmware from March 2020, and when it rebooted, it did go as far as optimizing the apps, though anytime it booted up, it would never get past the white verizon loading screen. It took me hours before I discovered that Odin was failing to load the firmware on the phone as the Windows 10 laptop only had USB 3.0 ports which don't always work with Odin, and ended up being successful using my old Windows XP laptop as the USB 2.0 ports worked fine. After a bit hanging on the verizon loading screen, it would reboot and never went past. I have been able to load the March and April 2020, though none of them will ever get past that white verizon loading screen. I did see something say that in loading TWRP, I could possibly do a full backup of the phone which is what I would like to do.
One time I only loaded the AB file for a different version than I had loaded, and it was the first time it went beyond the white screen, only to tell me that the verification failed and it would need for me to do a factory reset. I was able to reboot the phone without actually doing the reset.
I have read many posts here and the forums on androidcentral, and with so many things, I really needed to post to get guidance from people here that can point me in the right direction for any other things that I can try. As you have read, doing everything that I can to get the phone working by keeping my data. Any help would really be appreciated.
