Oh my, ashyx, are you telling me you have missed all the gems in this thread??? :p Have a look at post #780, #782, #797, #825 or some more of those from our "bro" DeHAWK. :cool:

Wait a second, what have we here (post #783)? Turns out you have seen one of them X files before, right? :cyclops:

OK, jokes aside, DeHAWK seems to be not the only one who is onto something. Take a look at post #851 for instance. What do you make of it? I mean, there is no such thing as mystery in software, only anomalies and even those can be reduced to some flaw or unpredicted condition. It is either that or those lucky ones have somehow managed to get their hands on devices without the hardware knox counter which normally would not have passed the quality tests and left the factory.

The X Files, Season 1, Pilot

Section Chief Blevins: Are you familiar with the so-called X-Files?

Scully: I believe they have to do with unexplained phenomena.

Section Chief Blevins: More or less. The reason you're here, Agent Scully, is we want you to assist Mulder on these X-Files. You'll write field reports on your activities along with your observations on the validity of the work.

Scully: Am I to understand that you want me to debunk the X-Files Project, sir?

Section Chief Blevins: Agent Scully, we trust you'll make the proper scientific analysis.

I fully agree with everything you have just said there about root etc. The world seems to be more controlled by corporations rather than by governments or legitimate regulations these days. That is the only explanation I can think of looking at what Samsung does or Sony with their latest release of XZ1 and similar devices where you will find yourself with a deliberately broken camera when you try to use the otherwise official bootloader unlock mechanism just because Sony would not stop whining about all the intellectual property they have put into their camera postprocessing software that needs DRM protection so badly. Hey Sony, have you actually tested your piece of crap little brick of a phone called XZ1 Compact with the same old design yet a shiny new price tag which could normally buy you a decent second-hand car??? And speaking of intellectual property, I think they have spent all of it designing yet another fancy DRM feature which got broken a couple of months later (in your face!). Only my good old web cam from back in the last millennium used to make better pictures. Right, I think I digress ... a little.

As for Magisk vs. SuperSU, the latter has certainly been around a lot longer and it is considered the number one classic for all the good reasons. However, despite all its compexity and "deep roots" as you put it Magisk to me is currently the 'pole sitter' simply because it can handle Safenet so nicely (among other things). If only they managed to come up with an xposed module that would not break their Safenet cloak (and some other modules for good measure), I would have the best setup on my device ever.

Still looking for some answer clarifications to these, thanks! There are multiple non-Galaxy Tab S3 XDA forum threads that are either outdated and/or give contradictory information - It would be better to know what's relevant to this Galaxy Tab S3-device series.

Have you tried flashing either version?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] esgie:
AFAIK, Samsung encryption - which is entirely different than the "standard" encryption used by Android - is not supported at all, neither by TWRP nor any other custom recovery, on any device. Or - at least it wasn't, a couple of months ago.

Hm, or maybe I am wrong and the situation has changed? Hope so, in the past I have left my S7 /data partition encrypted and now I am stuck with stock kernel and no access to /data via recovery, and also without the possibility of starting from the scratch as I cannot afford enough time to configure all my 200+ apps again...
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] sirscrubsalot:
This is how you can restore stock recovery-firmware-kernel if ever needed to restore.

Posting this for anyone who needs part of the answers to at least restoring back to stock firmware + stock kernel + stock recovery - it's from a self-post in the Q&A Tab S3 forum (I had to troubleshoot a kernel for this that would not play any sound through external speakers + youtube lag when headphones are NOT USED (with headphones, this is working fine) - perhaps someone has time to share their thoughts to improve the community support and development of this Tab S3 series.

[SM-T820] How to go back to stock firmware-recovery-kernel? NO SPEAKER SOUND-YT LAG:

https://xdaforums.com/gal...mware-t3701952

Thanks to [MENTION=3002995]joemill[/MENTION] for taking the time in sharing these steps -

To save time, you can do the same steps outlined above if you want to straight restore to AQI2 without doing the normal system update but I am sure it'll help if anyone needs to roll back to an earlier non-AQI2 firmware version. This was for the XAR-US SM-T820 Wifi edition.

Note: There are obviously still a few unanswered parts to the main question (a + c + d in quote above from me) asked and it still would be good to know these to at least be better in properly reporting and testing out other modifications to this device
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] w0rdie:
Yeah, Odin throws up on it.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
Not enough details.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
You make a full backup with TWRP before modifying. You don't need a stock backup.

Pretty much the whole point of a custom RECOVERY. The clue is in the title.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] mocsab:
Thanks for this - I was able to ROOT my T820 Tab S3 (US Varient) and all is working well so far - except - occassionally when I boot up - I get stuck in boot loops for some reason. The only way out is to clear cache and davlic - and sometimes to restore the initial backup I made when I first flashed this.

I want to start over and would like to flash the stock firmware - but can't find any for United States. All the firmware I have found is listed for other countries.

As this does not have a Modem - I wonder if that matters or not? (on my S7 Edge G935F) I can flash any firmware from other G935Fs regardless of the country - but I didn't know if that was possible here?

Any suggestions?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jonathonalexander:
To flash stock firmware for the UK, I used something called 'SamFirm' which finds the firmware on the samsung servers, it gives you four files in a zip, with those files you have to use the latest ODIN to flash. You can try and see if it also has the US firmware.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] mocsab:
i csnt find us firmware there or anywhere. can i flash firmware from othrr countries?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Knight1314:
I had the same problem. You can just do what I (and jonathonalexander) did, which is to download SamFirm and get it through there. You'll need to put a check on the Manual option and specify the following values:

PDA: T820XXU1AQBB

CSC: T820XAR1AQB9

PHONE: T820XXU1AQBB

I had to do this because Auto did not work. XAR is the region code for USA. Download and flash in Odin.

Edit: sorry, I meant to add that I'm in the USA and this worked fine for me. Unzip the downloaded file and flash the parts in Odin.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] mocsab:
I did exactly what you said and there was no file found using the information you offered.

I found and downloaded the Sam Firm and installed on my PC - then I entered the Model T820 and Region XAR and the three file names you gave - Copied and pasted into the correct fields - and each time I tried I got an error saying no file found. Actual Message was Could not send BinaryInform. Status code 200/400.

If you were able to download this - can you just post a file on your GOOGLE DRIVE or in a drop box or something? If that isn't possible, Any other ideas would be appreciated....

OH - and thank you for the help you have offered so far - even thought it hasnt worked yet, I do appreciate the attempt...

Just think how much time and effort you'd have saved if you'd just spent a few minutes making that all important backup with TWRP first. :rolleyes:
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jonathonalexander:
Ashyx . Do you foresee any danger from him flashing a firmware from a different region ? Just for the sake of interest
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
Not really. At the worst part of the firmware may refuse to flash such as hidden.img, but you don't need to flash the CSC anyway.

I usually just flash whatever is latest regardless of region.

The other consideration is the modem, different regions different frequencies, but that doesn't matter on a wifi device.

Sometimes there can be issues with some countries not using certain wifi frequencies that can cause an issue, but nothing that can't be easily solved.

In any case its still not too late to make a backup before flashing.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] mocsab:
I am not an idiot. I have a backup - I always make a backup - but I also ALWAYS want a backup of the stock firmware in case the SD Card becomes corrupted or something unexpected happens. I have been around long enough to know that even using OFFICIAL TWRP software, you can have issues restoring backups and it is always the BEST Practice to have a standby stock firmware handy in case you need it.

I am just trying to be practicle. But thanks for sharing....
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
Nobody said you were an idiot. No idea why you had to declare you wasn't. ;)
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] mocsab:
Sorry, I guess I was overly defensive by the comment that seemed to infer that I would have been better off if I made a backup. (I was only saying the original request was made for safty reasons - and that I had made a backup.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jonathonalexander:
Simply freezing apps works just fine although my OCD wants them removed. Root fully functional. Thanks for providing this.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] elchmartin:

Flashed twrp again, now it's there and settings are saved. Very strange. But i'd still like to thank you for the support! :)

Sadly my problem with the two mentioned modules on magisk still exist. Even through off topic: Any idea what this could be caused by? Flashing or installing isn't working but a manual flash of a nun magisk exposed zip is working fine.

how to restore stock kernel + stock firmware/recovey = answered here in this comment.

"Posting one answer that I tried and found it to work for question a) - restoring stock kernel if you flashed a custom kernel"

1. Extract "boot.img" file from AP-firmware "tar file" that matches my device (I used 7zip) and copied to external microSD card.

2. Restoring back regular stock kernel: booted to twrp > flashed boot.img via "install image to boot partition" > rebooted and noticed a bootloop with the galaxy tab s3 powered by android screen > turned off > went back to twrp > flashed "Boot image patcher-no-verity-no-encrypt_ashyx" (I already did this initially after flashing twrp through odin, not sure why it had to be done again) from my microSD card again > bootloop gone and boots up to system again > stock kernel now appears in settings-about tablet.
