[Q] Galaxy TabPro 10.1 T520 unroot - Galaxy Tab Pro 12.2, 10.1, 8.4 Q&A, Help & Trouble

hello,
i want to unroot my device and restore completely to stock and having hard time finding any tutorials on how to do it. Im running 4.4.2 stock rooted rom build# KOT49H.T520UEUAND1.
my specific questions is where do i get the stock original firmware for USA Wifi version, how to install it and how do i take off my TWRP custom recovery and restore it to stock.
Im not new to the whole rooting and unrooting deal as ive done it with numerous smartphones with no problems just i dont want to mess anything up with my tablet. a simple guide will be satisfactory thanks!

Go to sammobile.com. Click on the Firmware Tab and search for your model. If you are in the USA, use the cellular South firmware. Download it. Unzip the file. Use Odin to load it on your tablet (if you need instructions, let me know). It will wipe your recovery and unroot the tablet. You should also factory reset before and after loading. You will be back to stock

hey thanks man!

Thanks, I had same question.

Flash stock rom - Keep Root & CWM

Hello, I am currently rooted and have CWM 6.0.4.3. installed. I'm on CM11 but want to go back to stock.. Is there an easy way to keep root and go back to stock. Want stock for a few functions that ROMS dont seem to be offering but can keep root and CWM ??
Thanks.
Which phone do you have? You could try flashing a pre-rooted stock ROM via Odin. Then use Odin to flash CWM.
Bt its better to firstly install ur stock rom and then again root it as it takes no longer than 5 mins

Ok perfect, thats what I was looking for. Phone btw is S3 - d2att - SGH i747) Sounds good to install the stock rom and re-root.. I'm sure its here but I have searched everywhere to find a tutorial on this and I cannot find a straight answer.
Would you mind giving me the steps or pointing me to a thread that explains how to and has the files in need to download ?

Do you know if there is a step by step on this somewhere ? I dont mind going back to complete stock.. I can just re-root and flash CWM after.
OR
Maybe you could just answer the bigger question : the reason I want to go back to stock is I need to use MHL/HDMI which CM11 doesnt support. I dont want to go back to stock, I would rather even go to another ROM that supports mhl/hdmi.. but if I have to go to stock, than so be it.?
Were you running the stock AT&T 4.3 ROM before you switched to CM11?

Yes, I bought the phone new and was running stock, Canadian Rogers version and had changed to CM10, then to 11.

Since you installed a custom recovery, that would have tripped the Knox counter which voids the warranty. It's not a problem if the phone is working properly.
Did you update to 4.3 or did it come with 4.3?
You may be better off installing a pre-rooted ROM.

It was quite some time ago but I believe I was on ICS 4.0.. and switch to CM from there. Im not worried about the counter for warranty, that's expired on my unit anyways. I just want to be able to use MHL/HDMI function.. so if fine with flashing pre-rooted.. or stock.. or a different ROM that support MHL/HDMI. Can you recommend the easiest route ?

I asked about 4.3 because the 4.3 bootloader cannot be downloaded. Flashing via mobile Odin will not touch the bootloader or modem.
You could try a pre-rooted rom and then flash a custom recovery via Odin.
I use Philz Touch from here: http://goo.im/devs/philz_touch/CWM_Advanced_Edition/d2att

Ok thanks, I will do that. 1 thing I'm not quite sure of is the bootloader situation ? In the first tutorial there is a note : Flashing a prior bootloader can hard/soft brick your device. How do I know ?
I see the steps as:
Extract tar file you downloaded.
Use Odin, put phone into download mode [with phone off, hold vol. down + home + power ], connect to computer and open Odin.
once in odin click the PDA field and select the tar file
Leave Auto Reboot and F. Reset Time checked.
click start and when done let phone reboot.
If you just want a stock, rooted phone with no custom recovery, no plans to flash custom roms, etc. then you can stop HERE.
For my situation, is it just that easy ?
Before flashing, verify the version of your bootloader.

OK I have made an effort to go read and figure out how to find out what version of bootloader on my own.. But i cannot find ? Any chance you know... And could help?
You mentioned your have the i747 and Rogers. Do you have the AT&T s3 (i747) or Rogers/Bell/Telus s3 (i747m)?
What is the most recent stock ROM you had on your phone?
Hey. I got the i747m. As for what was the last stock ROM I had, can't say. I know when I bought the phone it was ICS and I had received and update to jellybean.. But them went to cm10. The tutorial I followed told me had me back everything up, which I did. Have it in a file somewhere on my comp, would that tell me ?

If you are flasjing back to stock you should flash back to the same baseband/bootloader that came stock on your phone.
I'm looking for a stock rooted zip for the sasktel i747m (MF1) that i can flash in CWM....I need to go back to stock to fix a data issue that ive encountered through flashing these new d2lte builds...

I have not seen a stock mf1 ROM that can be flashed in CWM. You could use mobile Odin to flash back to stock and then flash Philz Touch via desktop Odin later.
OK, so back to my question.. If I have the i747M and bought the phone with ICS.. does this help.?

Hey there Audit, Sorry to bother you again, I just dont know how to move forward from here and neeeeeed some help.
I have been reading for days and days have not found a straight answer for my issue and I dont want to just go ahead and start flashing when I dont know if its the right method ?
I dont know how to get back to stock from where I'm at, I dont know how to figure out what bootloader I have (you asked me)
I have found a couple links on XDA that I can follow, I'm just not sure if they apply to my situation ?
This is a pretty detailed response/tutorial, but I dont know if I can just go ahead with this or not ?

If you are sure you have the Rogers i747m and you have never loaded a stock Rogers 4.3 ROM onto your phone, you could use desktop Odin to flash a pre-rooted 4.1.2 ROM from here: http://forum.xda-developers.com/showthread.php?t=1739426.
Flashing the pre-rooted 4.1.2 ROM will return the phone to completely stock, wipe out all installed apps and data, and you will have root. I do not recommend flashing the Rogers 4.3 pre-rooted ROM from the link.
Once you are able to boot into the phone and set things up, you can flash Philz Touch from Odin which will give you a custom recovery on a rooted stock 4.1.2 ROM.

Question about downgrading from Kitkat to Jellybean on Galaxy SIII (SGH-I747M)

Before I start I will say iI did check out the search function for more than one hour and felt pretty lost amidst the technical discussion going on. I'm still reading about Android and learning so your help will be greatly appreciated.
I bought a Samsung Galaxy S3 (SGH-I747M) soon after its launch in Canada. It came with Jellybean and after a while I updated it to Kitkat using the "check for updates" area in the phones settings.
My question is basically is out possible to root the device after I updated it. Or is it possible to go back to Jellybean and then root it from Jellybean?
I have tried to flash the stock Jellybean ROM onto it and it just doesn't work at all. Odin loads stuff for 5 seconds and it fails.
Other than going back to Jellybean is there any way to Root my phone if it's on Kitkat now? I'm not concerned about warranty etc due to age of the device and it would be gone already anyways.
Thank You!

Once you are on KK, you cannot downgrade the bootloader so don't bother trying to downgrade to JB using firmware from sammobile.com. Do this may brick your phone.
Does your phone have a custom recovery? If not, you could try flashing Philz for the d2lte and install supersu from recovery.

No it does not. Thanks I'll try that. How do you install super so froom recovery and would i get root access?
Thanks so much!!!
In order to flash supersu, you will need to install a custom recovery onto your phone. Doing this will automatically void your warranty.

[Q] Help Can't flash Stock rom different carrier.

Hi there. I have a very simple question. I bought an AT&T version Tab s 10.5. I have tried Googling all over the web for this issue but I can't find a solution. I am very new to flashing roms. I have done it in the past but that was much easier back then. Last time I flash a rom was on a Google G1. Anyway the model of AT&T Tab S is T807A. I am trying to flash the Tmobile stock rom T807T on this tablet. Is there anyway I can do it? Odin fails at NAND write. Please someone help me out. I don't want to flash a custom rom. Just replace the AT&T rom with T-Mobile Stock rom. Thank You.

Att locks it bootloaders. That means you can only flash firmwares from att only. Sadly you can't install Tmobile rom on att
So what about T-Mobile? Is it's bootloader locked too? So I won't be able to install Custom FW on my AT&T Tab?
That means you can only flash att firmware on your att tab s. And Tmobile firmware only on a Tmobile device. You can install a custom FW on att tab for now
Gotcha. Thank You so much for your help. I am not so good with installing custom rom any guide you can reccommend. A forum sticky or post I should read where it tells me how I can install firmware. I don't care about the Knox warranty.
Made a big mistake tried to root the device realize couldn't. Now I am getting the error about device needing to connect to Kies 3 to fix firmware. Unfortunately Kies does not support this AT&T device so I am out of luck. Any idea or anyone know if I can find AT&T stock firmware and just flash it with Odin? Thank You

Try factory reseting in recovery. If that doesn't work then your out of luck there's no firmware for att. Sorry
Just go into recovery and wipe the cache. Factory reset will probably do it too.

Need to reinstall SGH-I467 4.4.2 update...help?

Ok. Got a Note 8 from a Pawn Shop for $80. However, I think that it has some software issues and I want to reinstall the stock 4.4.2 and eventually get root without using KingRoot..
Is it possible to wipe and start fresh from Kies? Or should I use ODIN? I downloaded an update.zip, but I'm lost when it comes to Odin.
Any advice would be appreciated.
Thanks
I'm afraid there's no way to do that, not without odin flashable 4.4.2 image. All you can find is 4.1.2 flashing which would corrupt the bootloader and put your device in soft-brick.

brand-new t999, stock 4.1.2 MD5, upgrade to 4.4.x? Please advise...

hello all, i have a fresh out of the box T999, firmware ver 4.1.2, kernel ver ends w/ MD5. i need to upgrade the firmware on this phone to 4.4.x so i can run the Amazon Flex Delivery app on it, and am kinda confused as to what the proper route is to get there from stock 4.1.2... im reading about 4.3 adding Knox, tripping 'Modified' switches, etc and really just need to know what the upgrade path is and proper order. im familiar w/ using Odin and custom recoveries, but also read that just installing a custom recovery on this phone will trigger it into modified mode in a permanent way. dont care about being rooted, i dont even think the Amazon Delivery app will run on a rooted device.
any advice or info would be greatly appreciated, thx in advance all..
The last official update to the T-Mobile Galaxy S3 was Android 4.3. If you want 4.4 or higher, then you're going to have to flash a custom ROM. If you aren't comfortable flashing ROMs, then you'll need a newer phone.
I suggest using Odin to flash the latest ROM to your phone, install the app, and see if it runs.
