Need help with my Galaxy S10+ (AT&T SM-G975U) - Android Q&A, Help & Troubleshooting

Recently, I had to install the United States Android system ROM (unlocked) in order to unbrick my phone. However, I am now unable to update my phone. The AT&T apps still work. Also, my phone will just randomly freeze and restart. Sometimes, apps will stop working and constantly crash and I will have to restart my phone. How do I install the factory version of my phone's software so I can download updates?

My Samsung Galaxy S3 won't auto update my apps

EDIT- IT WORKS NOW I HAD TO FACTORY RESET MY PHONE.
I've recently noticed that my phone is not auto-updating and notifying me when there is an update, even thought I have set it to auto-update and ticked the notification box. I found out I had updates when I clicked "My Apps" in play store I had several updates just waiting to be updated which were 2 or 3 days old. So I ended up updating them manually, I also found out that it only updates my apps automatically when i restart my phone. I've tried searching this(tried it in google as well) but no luck. Can someone please help me as I don't want to check for my apps regularly or restart my phone.
Thanks in advance.

Samsung Galaxy S3 resetting

Good afternoon all,
I have recently updated my Samsung Galaxy S3 via kies to Android 4.3. I couldn't do the update over the air as it was rooted. I had to go through and root my phone again through Odin and again all that went fine.
However since doing this I have had to restore my device 2 times as it shuts down every now and then and I find I 'lose' some apps...mainly games, which I find annoying. It also wipes any saved text messages.
At first I thought it was only losing apps that I'd downloaded through other means (i.e. not Play) but it appears not. I still have the apk files stored on the phone and have tried to re-install them but I get a message of 'app not installed'
Can anyone tell me why this is the case? As I have previously said it has only been since updating to Android 4.3. Not sure if it is due to rooting my phone (i'm guessing not).
Any help will be greatly appreciated
Chris

Please use the red report button and ask a mod to move the post.
See multiple posts re OTA and root problems.
Suggest factory reset if that does not fix then flash stock 4.3 through Odin .
I know that I can't do OTA updates... My problem is that the phone will restart, without warning and when it reboots I have lost all my text messages and a few apps. Trying to reinstall the apk files gives me the error 'app not installed'
I have tried factory reset both through the recovery mode and the system settings, but nothing resolves it.
My phone is rooted and runs Android 4.3 which was updated through kies.
The apps it loses are games so that's not a major issue... It's all the text messages.
I have a very similar problem, phone always shuts down and restarts on it's own. A couple of times it has lost some apps but usually it just starts up again fine but it's very annoying. Sometimes it gets stuck in a boot loop too.
A Google search for random reboot or random shut down brings up a lot of results but no solution's, so it seems to be a common problem. It's not just the stock rom either as it still does it when rooted and running other roms.

[Q] Help with Galaxy S3 softbricked by android update

Hello everyone,
I'd be grateful if anyone can help me out with a problem I'm currently experiencing with my Galaxy S3.
The phone basically won't boot. It powers on fine, goes through the custom logo (for my network provider, Three) and then goes into the Samsung logo. There it stays, unable to boot.
What I think has caused this is that Three notified me of an over-the-air update to Android 4.3 from Android 4.1.2. I downloaded the update, and ran it, but I don't think it completed successfully and so the phone's firmware is probably now corrupt.
I sadly didn't take a backup and would really like to get the phone working again without losing text messages, apps, app data and so on.
I've looked at various options. I have the correct stock ROM/firmware for the phone (H3G version of 4.1.2). I could use Odin, or I could probably install Clockwork Recovery and use that. But I don't know exactly what I'm doing and in particular, how to keep my app data.
Any advice greatly appreciated.

Trouble with Galaxy S4 i9500

Hello.
I have a Samsung Galaxy S4 i9500. I got it about 2 years ago. About a year after purchase I rooted the phone to install a backup software, but I did not know that rooting would disable software updates and when I found out that S4 had gotten the Lolipop update but my phone wouldn't show anything for two months, I decided to install the "original" Lolipop from Samsung. I found it on a website which I do not remember anymore.
Well here's where the problem starts - Apparently my phone was from Korea and it was imported to India. As a result of me installing an OS made for India on a Korean phone, the SIM wouldn't work and the OS ran very crappily. I got the SIM unlocked by an operator but the OS just sucks really bad. It gets stuck very often, apps close randomly and they behave as if they have been relaunched every 5-10 mins. Sometimes if I'm playing music the player will stop mid-track and I have to press play again. The menu and homescreen also do the same thing, keep behaving as if they have been relaunched every few minutes or every time I unlock the screen.
Any idea what I can do to fix my phone? I'm ready to go back to a previous version of android if that means a smooth, non-annoying experience.
Check your actual version of the stock rom from sammobile.com. Download the correct stock rom and re flash through Odin
Thanks, but I just ended up installing CyanogenMod and gotta say I'm more than happy with it :3

Galaxy S5 SM-G900V Samsung Account Lock: No WIFI to Choose at the Wizard WIFI Screen

I bought this phone which was freezing up. I thought that a firmware upgrade would do the trick. However, there was a Samsung Account of the phone and I was not aware of. The phone goes to the first set up screen, asks me to connect to WIFI but there is not WIFI providers to choose from. I click in the refresh WIFI list and the phone asks me to turn on WIFI. However, I do not have access to the WIFI on/off switch due to Samsung account lock. After a couple minutes the phone would again freeze up. Sometimes it restarts or it would simply stay in a black screen. I have to remove the battery and start the process all over. I have tried re-flashing via ODIN . I update the phone via Verizon Software Assistance to the latest firmware Marshmallow G900VVRU2DPF4. But I downgraded to G900VVRU2BOE1 Lollipop 5.0 firmware now. I also tried removing the account by flashing the modem.bin file but I get stock in the same spot. Guys, please help!
