Device management on the fritz after failed OTA update.

I seen this subject discussed but never really saw a answer, seems like everyone resorted to re installing firmware which I would like to avoid if I can.......
so, Ran into some trouble today trying to trying to do the 3e recovery mod today and had to reinstall stock firmware (using odin and gtg). Got root access and was up and running. I went to updates just to see if anything was there and a update started and completed. the phone rebooted and was on the white and red update screen for about 4 secs and the phone rebooted again. When it Got back to the home screen and got a message saying the update had failed. since then device management will not stop popping up. it stays in the task bar and if you use any process that needs it, the failed update screen pops up again and DM crashes and restarts itself. the message in the taskbar says "connecting to DM server" like its trying to get a update. how can I stop this without resetting the phone?

it shouldn't be a prob after you flash a new rom on it.
If it really bugs you, you can try freezing it or remove the update manager pak with TiBu

S6 (SM-G920W8) Sent for Warranty

I have sent my S6 in for warranty if anyone would like to know anything about how my experience is with samsung let me know.
Yesterday my S6 froze and started boot loop couldn't access the stock recovery I wasn't able to power down the device so I had to let it die. I was only able to get to download mode knox wasn't tripped. After hours and hours trying to fix the phone I was able to get kies to install the stock firmware to the device after everything was done no errors the phone restarted and no matter what it still didn't boot still couldn't access recovery or power down the device. What I did notice though in download mode Odin said "System Status: Custom" But the Binery is still "Samsung Offical" it had changed after I tried to save the device with kies. I am unsure if "System Status: Custom" will effect my warranty.

if you can get it back into download mode, then look for the knox code and if it changes from 0 to 1 or says 0x10000 instead od 0x0000 or anything changes besides 0 (0x000) your phone has identified that the system was faulted by the flash and therefore your warranty is now void because the knox security system has changed from the original setting. If it says custom most likely it has detected as well that the system was flipped but because you said it still says samsung official they may let it slide. But im not sure what that means i believe is that the phone is an official samsung and that the flash was an official samsung code but it wasnt the original code on the phone. Sometimes a flash on the phone will change the imei so that could mean why the phone is now custom, More than likely though the repair person will have to flash your system anyway and if that doesnt work then your motherboard isnt being read by NAND and you probably need a replacement, i have been up solving mine and calling eveyr technincian store, repair person, and customer service since my phone did what yours did about 3am this morning. Ive got no sleep had about 3break downs and sadly i think it needs to just be professionally checked. My NAND keeps getting a write fail and nothing is passing over to my phone. i can still get into the recovery mode to perform factory resets and cache wipes but it says dm-veridity verification failed and even after multiple factory resets and cache wipes and accidentally hitting the adb button it has led me no where but a continous boot. My phone is only 12days old. Samsung will cover it because i didnt knock my warranty or show evident of any faulting with the OS. The phone had done a update to a new firmware and once that finished i did a factory reset from the phone settings and when i went back to wipe the cache the phone shut down and since then hasnt been able to go past the logo SAMSUNG GALAXY s6 screen powered by android. So as upset and dissastisfied as i am with the phone, i definately appreciate all the youtube videos, forums, repair technicians, and customer service advice i got today. I have definately learned more than i needed to know lol and downloaded about every type of odin available and both firmwares for the lollipop 5.1.1. for samsung galaxy and the original 5.02 the 5.02 got the farthest in download until it shut down because of the written fail and then again because of COM port, but the other one didnt even get past system configuration so i guess something needs to be looked at immediately. If you know anything please do respond back to this message before i send mine off thanks a bunch lovelies:good::good:
my phone is a samgun galaxy s6 with model SM-G290P (sprint), i was originally on android 5.02 i guess but i got the phone activated in stores so when it was given to me from the moment i had it i was on 5.1.1. , i also noticed that my phone goes through odin mode easily but wont connect to the computer i have installed the smart switch, uninstalled after it failed to work with kies, i have installed the mobile drive individually and it picked it up on odin but wont pick it up on smart switch. I do know that if i can locate my s/n number then i can just plug it into smart switch to do the factory flash but i cant locate the s/n number being my phone is turned off. i tried the DEC,HEX AKA IMEI, ICC ID, RS UNDER THE BARCODE, AND none of these codes seem to be a valid s/n number. if someone could assist me with that i would be TREMENDOUSLY GREATFULLLLL!!! ALSO BEFORE i could just click my power button once and the phone would come on now i have to slightly hold it a few second for it to even show the logo.i have also noticed that if i charge my phone the phone loops otherwise if i go to download and cancel and then power on the device manually then it shows the logo once and then shuts off. so hurt you guys!

ALSO WHEN MY PHONE IS OFF I CAN SEE THE BATTERY IS CHARGING RIGHT NOW IT IS AT 82%, sorry for the caps i was typing and reading the phone. On the recovery mode update using ADB is disabled apparently and so is the option to update using external storage the apply update from cache is deprecated too and also when i started having a problem when i hit the power button home button and the volume up it showed the little android man died now it shows he is ok and up right like normal but the dm-verity verification failed still , I AM ABLE TO SEE EVERY LOG IVE RECREATED IN RECOVERY UP UNTILT EH VERY FIRST CACEH WIPE I DID THE DAY AFTER I RECIEVED THE PHONE. IS THERE A WAY I CAN TAKE THE IMAGE OR INFO FROM THIS TO REFLASH THE PHONE MAYBE?!!?!?:highfive:

Have patience. Your S6 willbe fixed soon by Samsung.

PROBLEM!!! my galaxy s6 is stuck in a boot loop.

i have not used my phone in any wrong way. i did not install a custom rom or anything. no root. randomly in my evedy day normal usage of my phone, it started to restart. and the the problem got worse and worse. for a few minutes, i will be able to use my phone but then my phone will restart and be stuck restarting. most of the times i cant even go into recovery mode. it restarts again when i get to that. i already reseted my phone, and i wiped the partition.
i have a samsung galaxy s6 SM-G920W8 telus/koodo 32 gb. i got the battery replaced by samsung but that didnt work. i noticed that after a few hours, my phone stops restarting when it reaches to 10% battery life.
WHAT DO I DO?? YOU GUYS ARE THE PHONE EXPERTS!!

You might want to try re-flashing the firmware. If that doesn't fix it, then you probably have a faulty device.

i tried reflashing but now i got "there has been an error updating the softawre. please use smart switch to recover" or something like that. and my phone is not supported by smart switch..... and when ever i try using odin, i always get NAND write error.i have a telus locked phone, 5.0.2 or 5.1.1 firmware. it is the latest odin and i have the drivers and i tried several solutions but that didnt help with the NAND write error.

Have you tried the original LATEST firmware from SamMobile? Using the original cable? The latest version of Odin?

latest telus/koodo version i can find for my galaxy s6 SM-G920w8 is 5.0.2. i only use my origional usb cable. i always get nand write error. my version is 3.10.7 of odin.
phone: SM-G920WZKATLS
locked to: telus/koodo
firmware: 5.0.2
i tried a 5.1.1 update too but that didnt work. i tried a rogers one but i still got nand write failure. on my s6, it says "
system rev. check fail device: 2 binary 1"

Ok...make sure you enable developer options...and enable OEM unlock....also go to security settings and make sure Reactivation lock is disabled or unchecked. ..then try flashing the firmware and it should go through just fine

i managed to flash a rogers firmware using the samfirm software but my phone is still restarting multiple times

My sister had a Galaxy S4 that would randomly reboot once in a while. Over time it became more frequent until it would barely finish booting before it would restart. Eventually it stopped turning on altogether.
Before it died completely, I tried different firmware versions and three different batteries and no change. I even took out the motherboard and put it in another S4 and it still wouldn't boot. Put the other S4's motherboard into the broken phone and it worked just fine. So it was something on the motherboard that died.
Sounds like a similar issue with your S6. Fact is, if a full wipe and firmware flash doesn't fix it, it's a hardware issue and there's nothing we can do.

Software Update Failed Message After Root

I was following this guide https://forum.xda-developers.com/ve...-to-notes-root-install-xposed-unroot-t3411039 on rooting my galaxy s7, I've never done any of this before so I was expecting to mess up.
I did everything it said everything seemed to work fine, but after odin said it was successful, the phone rebooted and continued to reboot over and over again not starting up. I put it back in download mode and tried to flash back to stock and odin gives me a failed message. Now my phone says "Software Update Failed"
newbie at this, pls help

Phone stuck on blue error screen

I accidentally deleted a photo and wanted to retrieve it. I found some software called DrFone which seemed to do something to my phone, I kept getting a security alert and I could no longer update my software because it had now apparently been modified. I have never root my phone and when I downloaded apps to check if it had been, it said status unroot.
I tried to manually update software with smartswitch and then my phone went to a blue error screen saying 'An error has occurred while updating the device software. Use the emergency recovery function in the Smart switch PC software'. I tried this but the recovery didn't work. I can only get to the download screen (all button pushing combinations wont work). I have also tried odin but that didn't work. Can my phone be fixed?
