Question Faster way to unroot sm-x200 - Samsung Galaxy Tab A8 (2021)

I am rooted and running a rooted stock rom. I have no need for the tablet to be rooted and I want to go back to stock to see if it has gotten any better than it was when i rooted. I am currently downloading the stock firmware but it is seriously taking forever. Is there a github somewhere with the stock firmware someone can point me to.

You can try using Frija to download the firmware directly from Samsung's servers. Other than that, Sammobile is your best bet, but downloads are pretty slow.
Either way, once the firmware is downloaded, extract the files within it and use Odin to flash.
As for whether it will be better....Probably not. Samsung loves to stuff bloatware into their firmware, and the Tab A series are low end devices. I have a Tab A 8.0 that I ended up running an AOSP GSI on, and it's still slow as frozen snot.

Recently installed the latest version of Samsung's firmware - X200XXS2CWD2. After debloating, you'll be able to speed up the system.
However, that doesn't even come close to the increased performance you'll gain by flashing a GSI. The only problem is finding one which works well with this device

Lollipop 5.1.1 on T715?

OK I'm a complete newbie here. I bought the 8" S2 International unlocked version from Amazon and will take it to AT&T to activate it tomorrow. It's on 5.0.2 and is not seeing any OTA updates. Does anyone know if there's a way to get 5.1.1 OTA? If not, does anyone know if Samsung has commented as to whether they'll release 5.1.1, or even Marshmallow, for this device or will I have to go to a custom ROM?
Also, is there an absolute beginners guide to this site? I've been reading through the threads and keep seeing terms like odin, twrp, and many others that I don't know what they mean and I'd like to figure out.
Thanks.

i just received the same device yesterday and so far, it's working just fine on at&t: including data full phone features (i wasn't aware that this version of the Tab S2 had a full fledged phone). i inserted my nano sim from my dual-sim note5 and the S2 configured everything automatically. also, i didn't see an OTA when i checked yesterday and there's nothing at sammobile.com which is where one can generally find firmware (stock ROM) for Samsung devices. any custom ROM right now will likely be 5.0.2.

Odin = Windows based application used to flash firmware to Samsung devices.
TWRP = a custom recovery that - once your phone is rooted (similar to admin privileges on windows pc) - allows one to flash a custom ROM or other components/features not on a stock device. you can also create backups/nandroids of your device so you can restore your device if something goes wrong (similar to resorting a windows system image to a new hard drive). always, always backup when trying things out. tutorials are here, but sometimes not easily located via search. :good:

Just purchased N910T - has COD6 firmware, should I root now or upgrade first?

End result I would like is TWRP and custom ROMs. Not new to flashing but I just received the phone today and am used to the open world of the Nexus 6. Seems there are a few guides on here for both older and newer firmwares, the phone I got has COD6 on it right now. What's my best course of action? I'm thinking the newer roms need the newer baseband but I want to make sure I can get TWRP on there. Thank you in advance.
Odin to latest firmware and start from there. You decide to root or not. Here https://forum.xda-developers.com/no...firmware-galaxy-note-4-n910tuvs2eqb1-t3569911
Keep in mind once you upgrade past 5.0.1 there's no going back....5.1.1 will be the lowest you can go..I prefer 5.1.1 but that's just me

Best or easiest way to update android version?

I'm using a SM-T710 running 5.1.1 that's been rooted. I've been on the same android version for years, and now some of the apps I use for my business are starting to run into issues. I'd just like to update the most painless way while still maintaining root. Is there a higher version that still runs well without any drawbacks like hardware not working?
If you want stuff work at least as good as possible and don't plan to tinker a bit... Your device was updated up to Android 7, but not when /system rooted. You need to load the firmware yourself and Odin flash it or do a reset with Samsung's softwares to the newest official one.

Need help with flashing firmware on Note 9 (noob question)

I have Note 9 (SM-N960U1) unlocked in USA. I am currently on AT&T.
I seem to have many dead spots inside my house so want to enable wifi calling but found out that I need to flash carrier specific firmware on my phone. As I am complete noob, have some questions:
1) What does flashing a firmware does? Pros? Cons?
2) I am currently on Android 10 (One UI 2.0 Build QP1A.190711.020.N960U1UEU3ZSL2). If I flash a new firmware, will my phone be downgraded to a lower version of Android?
3) If answer to @2 is Yes, how will I get latest Android updates? Will it depend on Samsung or AT&T?
4) Last but not the least, HOW THE HELL I FLASH THIS FIRMWARE?
Any help will be a great help. I have a interview on Friday so don't have much time to get this fixed.
TIA.
1) Flashing is a way to manually install or update firmware or operating system through the bootloader. This provides a way to restore the devices operating system during an emergency or failed OTA Update etc. The cons of this however is it is quite easy to mess up your device if you don't know what you are doing. And Flashing different firmware that is not originally meant for your device easily carries this risk. The bootloader is what tells your device how to boot the operating system and happens before any user interaction knock on wood you theoretically corrupt the bootloader or somehow mess it up you are left with a 1000 dollar doorstop. Im not sure how a carrier's firmware would react on an unlocked phone. I personally wouldn't risk it but it's up to you. I'm pretty sure that other users here have tried it you should look around and do your research. Remember this would not only be changing Android this would also change the CSC and Modem.
2) Android 10 has not yet been released for the Note 9 so I would assume that you are on the beta. You would need to factory reset and downgrade to Android 9 before flashing ATT's firmware.
3) Carrier's handle OTA updates. However im not sure you would even receive OTA's anymore.
4) You need to use Odin3 and get the firmware from somewhere like sammobile.
In conclusion I personally would advise you to contact ATT with your problem. Considering your interview tomorrow if something did for some reason go wrong you most likely wouldn't have time to fix it.

You have SM-N960U1 with One UI 2.0? Did you just buy it used? You are on bootloader 3, so you cannot flash another firmware with bootloader less than 3.

GO Back To Basics

Hi there, I will keep this as short as possible and jump straight to the topic.
I have been using various custom ROMs for the past two years- some were excellent and others not so good. Despite the awesome Exynos 7870 community and devs that provide many superior ROMs, I decided to go back to the Stock ROM since I am planning to resell my device. With this glorious purpose, I installed the stock firmware from Sammobile with the help of Odin 3.14.1. I experienced nostalgia going back to android 8 from 10 (was using A7 Port from Astrako before).
It worked and everything seemed fine until I opened Samsung Pass and to my surprise it said that my device was rooted and I could not use Samsung Pass. Not that I care using it anyway but it is the root that bothers me more. I thought I had completely gone back to stock after installing the stock firmware then why does the root still persist.
I need help un-rooting my device and get a 'completely stock' experience.
Please help!
Your device is as stock as it gets when Samsung pass says your device is rooted it is not actually rooted it is just that Knox was tripped the first time you rooted your phone and so the app thinks your phone is rooted unfortunately there is no way to undo this since know is an e-fuse.
