T-mobile OTA update g960usqs2arf4 fails - Samsung Galaxy S9 Questions & Answers

I have T-Mobile Galaxy S9, not rooted. Recent OTA update g960usqs2arf4 fails to install. It boots into the flashing screen with android logo, the progress bar gets to 30% and then it says "Error". I tried wiping cache partition but it did not solve the problem. I really want to avoid factory reset ... Maybe I can install it via PC?

Still stuck at this. It attempts to update roughly once a week and always fails and sends report to Samsung. Any suggestions?

Recovery update & Firmware update question

Hi Everyone,
every time i boot my note 7 to recovery, it says "installing system update",for about 30 seconds, then fails and lastly goes into recovery. I have never seen this in my previous galaxy phones, i also never attempted to update the device.
1) Why am i getting this? does this happen anyone out there?
2) Does This phone automatically update without my consent??
My phone contains the PH1 firmware, and i do intend to update as i want to root this device, i also flashed ATT firmware i still get this "installing system update" and then fails, then recovery
currently keep the phone offline out of the fear of auto updating.
3) How do i get rid of this??

installing system update error loop

I have an unrooted stock Samsung Note 8 that got an OTA update and is now stuck in a loop trying to install it but always ends up showing error after the install apparently fails.
This was never rooted and it was just factory reset prior to the update, and the update was something small like 7MB or something. I think it is on android 4.2.something. I can get it into Odin mode but since it is completely stock I am not sure if that will be enough. I am guessing I will have to figure out how to connect it to a PC and flash new firmware but it has been years since I have done anything like it and don't even know where to begin.
I hope a good soul in this forum has enough patience to point me in the right direction.
Thanks,

"Error occurred while updating..." Think I have bricked while attempting to downgrade

"Error occurred while updating..." Think I have bricked while attempting to downgrade
Please help.
I was attempting to root and SIM unlock the SM-G925T. It was already on Nougat 7.0 (and November 2017 security/patch).
CF Auto Root would not work. Neither did an attempt to manually flash TWRP (although attempting one of those two tripped KNOX).
I thought I'd downgrade to Marshmallow and then re-attempt root/unlock. Downloaded "G925TUVU5EQC2" from gsm-firmware and tried to execute via Odin.
I am left with a permanent blue screen with that "!" reading I need to use Smart Switch's Emergency Recovery. That, btw, does not work either (and neither does re-attempting after reinstalling device drivers from within SS).
Could someone please suggest what I should do? Pressing and holding power/home/vol- keeps taking me back to this blue screen. Unable to get to the recovery or anywhere for that matter.
Ok, so... Despite not seeing any other screen, I went ahead with reflashing the Marshmallow ROM via ODIN. Worked this time and the phone rebooted.
Interestingly, now, my unlock request was approved by the Device Unlock software (didn't need to use other means). However, I am stuck on Marshmallow and the device won't update to Nougat (get the error "phone not registered", despite it being unlocked). Hilarious. But at least the phone is functioning now.
Followed the same ODIN method and flashed the latest 7.0 image (Nov 2017 patch). Thankfully, it retained the unlock. Not sure if it can upgrade (I don't see the "not registered" error) but I won't know till there is a release.
Briefly got an annoying "com.sec.vsimservice stopped working" error - booted into Android recovery, wiped cache and did a factory reset. Working now!
Had already tried rooting this version (using both CF Auto Root and TWRP), but in vain, so not harbouring hopes now. Will get back to it later.

Moto z2 force t-mo update failed

Hi, I was rooted Magisk and twrp installed, I kept getting a notification of an update but just kept ignoring it. About the same time my phone started dropping signal all the time so I thought it might have something to do with the update. I went back to full stock 27.1 . When I try to get the update it downloads it and when it gets ready to install it says working in the background it shows a progress bar for a sec then pops up a screen telling me that something went wrong and update failed and nothing was changed and i just click ok. I get no type of error messages or any thing explaining what the problem is. As of right im not rooted or any custom rom or recovery installed just bootloader unlocked, SO what did I do wrong and how do I fix it???
When you say you went back to stock, do you mean you factory reset or you went as far as doing the flash-all?

Click to expand...
Click to collapse
I did the flash-all...
I too did a flash all after installing the OTA, now I can't install the OTA anymore.

Software update broke my phone? software not authorized by AT&T message

I received a notification for an update today, so I went ahead and did it. It completed one cycle and then rebooted and began a new cycle. At 30% the android mascot fell over and the update failed. This continued for 10 minutes or so. I then shut the phone down after a reboot and it went to a boot loop getting to the Samsung/Android logo. I read that going into recovery mode could fix the issue with a wipe cache and restore, only, trying to get into recovery mode gives me a blue screen with an message saying "software not authorized by at&t is installed on the phone".
I bought the phone today and did not do much except mess with the streaming apps. I did not try to root or install custom roms and I believe the error is due to the update not completing. Is there a way I can fix this or should I just take the phone back to at&t and get a new one? As I said, I bought it today (technically yesterday I guess).
Thanks in advance for the feedback and advice
Try flashing the latest firmware from sammobile or updato.com or use the samfirm tool from XDA (fastest) and ODIN 3.13.1 to flash it
Use CSC and not HOME_CSC
Flash all 4 parts together
This will not void warranty or trip knox
