Root worked fine for some time and then suddenly fell into bootloop - Samsung Galaxy S7 Questions and Answers

Hey guys, just wondering if anyone has an explanation for this.
I have T-mobile Samsung Galaxy S7 G930T and had working root for quiet some time until one day some apps started to crash. So I thought I would try clearing app cache and rebooting. Thats when the phone fell into a bootloop and got stuck on the Tmobile logo. I was able to boot up with factory reset but still would fall into bootloop again when restarted. So I redid everything by going back to stock and reroot. Now everything seems to work fine but I was just wondering why that happened? I mean its not like I'm getting bootloop while rooting but all of a sudden after its been working fine for quiet some time. I wouldnt want it to happen again since its a hassle setting up everything.
I am on the latest PIA firmware and could it be google and samsung security are catching up? I think there were rumors where your google accounts could be blocked for rooting which seems highly unlikely. Many are also rooted on PIA firmware but I havent heard of anyone mentioning this. Anybody care to explain to this noob?

"Unfortunately, SDM has stopped" HELP!!

Hello all. I rooted my S3 on Verizon a few months back, but the method I used did not work so I ended up unrooting it and factory resetting it. After that, I noticed that when I went into my setting to check software updates, it freezes for about 4-5 secs and I receive a pop up that says "Unfortunately, SDM has stopped" and since then I cannot figure out how to fix it so I can get the updates. I am now currently rooted and on 4.1.2. Any and all help would be much appreciated, thanks!!

Anyone? I could really use the help here.
Do you have sdm froze in titanium back up? If so, UN freeze it.
If not. You may have factory reset and/or refresh your rom.

That's a negative, ghost rider. Titanium says it wasn't frozen, but I froze it and unfroze it anyways and still didn't fix it. Also did a factory reset when I first noticed the problem and today I re-installed the stock rom. Talked to verizon and all they could tell me is that I more than likely need a new phone since it's still under warranty. I mean if I can still get the update using Kies, that's fine. If not... then I might take it in.
Is it possible to uninstall the SDM.apk and reinstall it? If so, do you think that would fix the issue?
I don't know.

[Q] Can Only Boot to Recovery

About 30 minutes ago my phone was working fine, the last thing I remember doing was sending a text. A few minutes later I look down at my phone and notice it is in recovery. At this point I'm confused wondering how it got there, but figure it's whatever and reboot into system. It reboots back into recovery and at this point I'm kinda freaking out. I do a backup, wipe, and restore from a backup ~2 weeks ago. Again, rebooting just causes my phone to go into recovery.
Earlier today there was a notification on my phone about an update but I just ignored it as I didn't have time to deal with it. I assume that it automatically was applied and that is what caused this problem.
edit: If you have this problem, try this: http://forum.xda-developers.com/lg-g3/development/fix-stuck-custom-recovery-trying-ota-t2907508
Same thing just happened to me.
I turned off OTA from earlier today and also removed the notification using AppOps and now I can't boot to anything but TWRP

Was coming here to say this worked - I was already doing this.
I'm back up and running again.
Not sure wtf caused the issue - I didn't take the OTA and have been fine on the phone all day until just now

I was the same - the zip file fixed my issue - didn't have to start over
Gotta love XDA.. i was getting ready for bed.. saw a bright light, it was my phone. Same thing as mentioned. only rooted and bumped. Have been denying the OTA. Even did the hidden menu trick, but still got notifications for some reason. Flashing the ZIP showed success; trying to restore my back up now.

Once you flash the zip you shouldn't need to restore. I just clicked on reboot system and was back in

Well i had to restore the newest back up, because I restored an old back up to see of it would reboot correctly. All works fine now. Still very weird.

I mean I still have Root and TWRP, I might have factory reset in my panic last night before finding the fix above. Probably the cause of losing all my apps and data
ATTT Forced UPDATE
It would appear after cruising the forums this morning that ATT forced an update to all users last night. It happened to me and many others like yourself. even people that had turned off updates in the hidden menu. It is total crap and not to happy about it obviously. good thing it sent me into a boot loop, and @autoprime zip fixed me up, even though i was back up on stock rooted, I took this opportunity to move over to the PoweruserV1 international rom to attempt to keep this from happening again. Luckily our DEVS are getting development moving and soon this will be a thing of the past....
I froze Software Update with TB and did not get auto updated last night and have not gotten any new nags today. I did try to update yesterday and got the stuck in TWRP thing and flashed the fix to get back working.

whats the name of the apk to freeze? Thanks
Just adding to this, that it was 'forced' onto me as well, and also sent me to soft brick loop (TWRP), so I'm having to use the get out of jail thread. THANKS LG!! YOU GUYS ROCK!!! (#[email protected]%&*!!!!) This is the LAST time I trust another corporate BS liar's announcement that they care about the 'community' and are going to try and be nice 'from here on out'. Moving forward, it will be NEXUS and nothing else for me.

It is called Software Update in TB. I only have it frozen since last night so hopefully this does the trick...it also removes update option from settings FYI.
Anyone else have this happen again last night? Phone was fine at 5am, woke up at 8:30 to recovery. Flashed the same zip and now it's all fine again.
Freeze software update with titanium backup so your phone doesn't try to install the update agian
wow att and their updates f*** with everything, currently having a locked s4 with old firm of mf3. i plan on upgrading my device but on the fence with all this lock down bs. switching to tmobile seems like a decent option...... so confused and undecided

How to stop lollipop from installing automatically?

I have just noticed my G3 is taking the ota without asking for my approval. How can I stop it from doing it again? Thanks in advance.
Secret Menu
I went to the dialer keypad and typed in 3845#*850#, the 850 is my model number. Change it to your model # and secret menu will appear. Tap on WLAN settings and it will show OTA updates and pick disable. That's it. Worked for me.
Did that but the phone will still try to install. The reason I know is because my phone will be boot looping in twrp. At first I thought I did something crazy until this morning I saw a message saying phone will install update and will reboot in 10 seconds. Good thing is that I have the boot loop fix zip file in my sdcard.
I kept having this happen to me as well, even after disabling the option in the secret menu. I ended up installing the 855 minus 5 ROM.
I actually had that happen as well. My whole system was gone and stuck in twrp. I downloaded the copy of the 10f stock file and the zip fix file. Thought everything was good, then the update popped up again in the notifation bar, so I made a backup in twrp and tried disabling notifications. The next morning it started to auto install and it failed. Stuck in twrp again, ran my backup then disabled notifications again. Haven't seen the update again in the notifications. Hopefully it won't come back.
Using TiBu, I disabled/froze com.leg.lgfota.permission and Software Update and I have not had any issues.

So I tried Titanium Backup. Couldn't figure out how to do it. I also noticed I couldn't send or receive MMS pics. Did some searching and on Google Play, there is an app called Disable Service. Download the app, open it, click on system at the top, scroll down to Google Play Services and click on it. Scroll down to SystemUpdateService and uncheck the box. I also went down to software update and unchecked all 3 of those boxes. Restart your phone and you're done. I also re enabled the setting in the secret menu. Now my pics come through again and the update disappeared when I restarted the phone.
Can the OTA be undone?

This may be a dumb question but I had something similar happen and I'm desperately looking for a way to reverse things. My D850 was rooted, still stock but tweaked to PERFECTION, and I was under the false impression that the OTA checked for root and wouldn't proceed, so when I got the notification that the update was available I dismissed it and didn't think about it. Next morning I woke up to find the OTA happened without any action from me and of course I lost root. The phone is now really sluggish with numerous nuisances and I hate it. AT&T really f'd up my perfect G3. I chose not to factory reset or clear the cache as some have suggested to improve performance. I guess I was hoping that with everything still installed there might be some hope to regain root.
I'm reading about people going back back and flashing zip files but I don't get how it's being done. I did not have a custom recovery installed but I did have a backup with Titanium, although I obviously can't get into that now without root. The really odd thing is that Softcard still thinks it's rooted and won't run. Anybody have any ideas?
Thanks,

I'm afraid you wont be able to go back to rooted kitkat without having to clean install as there is no root for Lollipop yet.

Hey aybarrap just curious if the TiBu freezing has held up. Took your advice and did the same. Just curious if you've had any issues so I can be on the lookout.

I have NOT received a single nag or download for OTA. I have had these frozen for over two months without seeing any issues in the phone's operations. In fact I waited 10 days after the 10f was released before installing and had no issues.

Voicemail issue after 6.0.1 update

Hey all, after the marshmallow 6.0.1 update for my Vzw note 5 my voicemail is not working correctly as it had before. I am getting this error of the picture attached.
The phone has been restarted multiple times, not sure what to do here. Any help is appreciated.
Thanks!
try resetting the phone and fresh install of marshmallow.
^ yeah I figured that would be a last resort, not into resetting my phone and was hoping for another work-around... Been out of practice of resetting since this phone is not exactly root friendly it was easier when I would reset and flash monthly lol.

S6 reboots when locked

I have a HUGE problem. Everytime i lock my phone or it locks itself, it turns off or reboots.

As far as I can tell it is not. It happens on fresh installs as well as backups :/
I think I finally got rid of the problem by restoring from an old backup through Switch.
Been 30 mins and no reboot yet.
Will come back after work with results from the day.
Update: back to rebooting.
Doesn't happen when an app is playing music/radio (Spotify etc)
Is there any way to get back to 100% stock?
Had to use twr to get out of bootlooping.
Or a link to get a working custom rom.
SMG920K is my model. Swedish version.
