Help a novice please - have ROOTED Samsung Galaxy Tab Pro 8.4 (SM-T320) - Update?

I just received a used Samsung Galaxy Tab Pro 8.4 (SM-T320) - and discovered (not known to me before purchase) it is Rooted.
When I went to do an Update via standard Settings>about Device - it refused returning tablet modified.
also it had the App SuperSU (free) installed) which asked about permission on a couple of Apps I used.
I have absolutely no experience of Rooted tablets,
and currently have no idea how the tablet was rooted, and what with.
So I am seeking your patience and some advice about this, please.
Is there a way to return to the Stock installation?
If so, how to I check that this is possible?
Or should I keep the Root?
If so, how do I update the tablet?
eg: how do I check what, or if any, custom ROM has been installed?
or
which custom ROM do people advise I install?
Thanks for any advice.
Vincent

Just back up your valuable data and storage contents and flash stock via Odin. And I believe at this time point the updates are not of much importance, so if you're on KitKat you might as well ignore that if you can't spare time for backups.

Thanks for the reply.
Funny that was starting to be my take too.
Either leave it rooted as is - since it really is just KitKat 4.4.2 - but with more ability.
Or later when the spirit moves perhaps upgrade via a custom rom.
Thank you.

@vincent. I have the same tablet as you and I prefer to run the latest OS which is Marshmallow. As you state you are already rooted so you might as well try out a custom ROM. I recommend Resurrection Remix ROM by Vasumit and the XDA thread can be found here. Latest update to ROM is here. You will also need to install gapps. I recommend Banks Dynamic Gapps 6.X.X found here. Give it a try, I'm sure you will like it. ROM is buttery smooth and Vasumit updates it often. :good::good:

Thank you so much for your encouragement and suggestion.
Even though I have used Android on tablets and phones for years -
I am still a n00b when it comes to Root and Custom ROMs
I have heard of the more famous ROMs like CyanogenMod etc -
what makes Resurrection Remix ROM by Vasumit better than CyanogenMod
in terms of features and/or support please?
How easy (or not) are custom ROMs to undo?
Many thanks,

Personal opinion below: most AOSP-based ROMs have equal or slightly better support than CM because the team behind them is much smaller, but they might die out one day because of the same reason. CM maintains a huge number of devices and is the basis of many, so it's not likely to disappear soon. Also, CM is usually among the quickest to get to a new Android version while others usually sync from CM and start from there.
As of features, others are guaranteed to have more than CM. CM doesn't like adding features these days.

Do: Flash TWRP, make a full backup of your stock ROM, full wipe and flash the new one.
Undo: Full wipe and restore the old backup, or if you decide you don't want your data, use Odin.

Thank you very much for the very helpful reply -
this was about as good as I was hoping for -
really appreciate all the help I am getting here, thank you.
It will take a bit of time for me to get my head around the information - as it is all new to me -
and I want to proceed with care/caution so I don't end up bricking my tablet.
Gratefully and thanks,

Hey!
you could look at it this way, most of the people here have a hard time just ulocking the device and rooting it, not that yours is already done, might as well right. along with the proper research, your device could be one hundred times better, the stock OS of the tablet isn't that good (lets face it.) and with the current technology, it will have a hard time keeping up because the OS for this device is not that efficient (personal opinion). Anyways, it's still up to you to do it or not. Cyanogenmod has released the nightly version of Marshmallow 6.0 for this device. maybe you could check it out!! ^_^

Yes, thanks for the encouragement.
Seems ironic that I had done lots of look-sees (not quite research, but close) about rooting devices - and I actually now have one
(it was just unexpected on this Samsung Galaxy Tab Pro 8.4 (SM-T320)).
As you see I've decided to keep it rooted and am actively looking at which ROM to flash -
currently I am leaning toward the more conservative approach of doing the CM (CyanogenMod)
and rather than deciding between the snapshot CM-12.1 or the nightly CM-13.0....
perhaps I should just wait for a snapshot CM-13.0
(" and we’ll have a quality approved SNAPSHOT for CM13 sometime Jan." of course it is now Feb - so maybe soon?)
Thanks,

Don't wait for snapshots - they are just forked from nightlies at a certain timepoint and aren't more stable than nightlies. Just backup and flash a nightly, and if anything you feel unstable, restore the backup and/or wait for that to get resolved. I personally don't see anything disturbing aside from wonky external SD support (which is a universal bug across all 6.0+ ROMs).
P.S. The "Thanks" button is there - use it

The issue is mainly with how to use SD card as external storage (as on older Android versions), not with the new "adoptable storage" feature. That we don't have a definitive solution yet.

Official Lineage Os Builds start flowing.

The Robin is the second device with Official Lineageos Builds available.
Go to Lineageos.org
Downloading now
Installing

https://download.lineageos.org/ether
To save some trouble, here's a link to the Nextbit Robin builds.
How's it running for ya?

Literally right after i flash back stock for the nougat beta.... XD

First impressions? Like Gps and fingerprint (no detection when unlocked?) are working correctly?

So... which version should we download? Experimental or Nightly?
Edit: Ok, Experimental builds are made for upgrading from a CM 13/14.1 build to Lineage. You can try it, but there's no guarantee that it will work. So the correct answer to my question is... Install Nightly. (And i will in a few minutes )
Btw, i was surprised our beloved Robin was one of the few first to have support from LineageOS. Thanks LineageOS people! :good::highfive:

Nice video! Definitely cool to see how the ROM runs in realtime. To me, it seems a little rough around the edges compared to stock, so I'll wait for a milestone build or something. Videos like this are super helpful, though, so thank you!

I most say Its not perfect, and it is technically not a first release, however this is definitely a BIG step on the right direction :good:

Best Nougat rom for Nexus 7?

I am looking for a ROM that runs android nougat. I have a rooted device but have never installed a custom rom on it. Right now, it is just running 6.0.1 MOB30X, the latest update on stock. I want to upgrade to Nougat, but I don't really know what options are available. I want to keep my device close to stock android, like it already is. So, if someone could tell me what ROMs are available and which ones are the most popular and best?

If you want to keep close to the stock android the closest is the official lineageos build. All others have added features which may or maynot affect batterylife and performance.

LineageOS or AOSP will get you what you want.

In my experience no version superior to "Android 6" works well "out of the box" with full working applications of estreaming like youtube, netflix, etc .. and sometimes problems with root, my recommendation if it will be "Android 6" is still better Stock rom. Neither lineage nor much less AOSP and any derivative.

Newbies to all these updates and ROMs releases. I spent a good amount of time dumping various ROM.
I tried Lineages, Droid, Resurrection Remix. I think ASOP is Lineage?
All the ROMs above works well but I could not get gapp to going. Keep saying wizard error when starting up. Gapp is basically play store.
I tried that mini gapp bean and the open gapp 7.1 pico. They both fail during start up. It was trying to run the google apps wizard and keeps failing.
I ended up with Nitrogen-OS-flo-20170316 ROM. Let this ROM flash first than, reboot, go back in recovery mode and flash the Gapp 7.1 pico. This was the only way I can avoid the wizard failing during startup. Everything works except Latest netflix app failing. Get the apk from mirror apk and make sure you get the older apk version 4.2. Don't get the newest 5.x netflix release.
Resurrection Remix ROM looks cool. It's suppose to be faster than Linage.
Since everything is work for me with Nitrogen. I'll stick with nexus 6 Nitrogen for now.
or until someone prove me wrong. Or know why I am having all sort of issue installing Gapp pico on Resurrection Remix, Linage, or that Droid version.

I am not sure if Android 6 or marsh mellow is the best. After I flash with Nougot. It's a lot faster. Loving it.

Hi guys, I just bought a Nexus 7 and i updated to latest official 6. Then i find out OTG Support doesnt have support for exFat, only FAT32. If i try to do Nougat, will it gain exFat support for OTG?
Also can anyone take my nexus 7 and do it for me for like $20-$30 as i am completely illiterate on all of this...

This depends on the rom or kernel as much as whether it is Nougat. LineageOS supports exfat and has clear instructions on how to install it.

[ROM] [Unofficial] [LOS15.1] Lilly's LineageOS CookieJar

Hi everyone!
This is just my corner where I drop the builds of Lineage-15.1 that I personally use. They do contain a few smaller customisations, like a custom kernel and other goodies that I personally need. I'm posting this here in case somebody finds them to be useful.
Nooby Disclaimer:
I'm not a developer and just because I've got a thread here, doesn't mean I fully know what I'm doing when modding or building ROMs. What I publish is used by myself personally and thereby tested as daily driver. If something still breaks and your phone doesn't survive the smoke test, that's your problem and not mine.
Builds will mostly cater towards my needs if I have any special wishes with the hopes that the changes are useful or interesting for someone else as well (won't be too deep changes I think).
Some info/bugs specific to this build:
SELinux defaults to permissive
Make sure you tell OpenGapps to keep LineageOS Snap installed, Google Camera crashes.
Fails SafetyNet Test, don't use if you need that to verify.
OTA Support (Can somebody confirm that it works?.). The Updater should notify you of a new version.
Other than that, there's not much to say about it. It's LineageOS 15.1, what more could you wish for?

I'm going to ignore the passive-aggressiveness and just go ahead and argue that with time that my builds will deviate a tiny bit from vanilla Lineage here and there, be it only tiny tweaks and goodies like Pixel Navbar, kernel with Kali Nethunter support and OTA support. Besides, I wouldn't expect a 14.1 thread to contain Lineage15.1, now would I? Fss.

No need to get snippy. Just commenting that I've been running builds for weeks now bringing up 15.1, and there's 40+ people in the hangouts group I made. I can't stop you from releasing builds or building from my sources (and nor do I care to), just letting you know that it's incorrect to say nobody's been building unofficials.

Sorry, I do apologise, but your comment did sound passive-aggressive even after reading over it multiple times. My point still stands though.

Not sure what you are asking, but I had to override the build type branding to NIGHTLY in order to have the OTA server working. Just flash it over the old version. If you're using twrp and it doesn't want to flash, I'll have a Lineage recovery here, flashing that and then flashing the update using the lineage recovery always worked for me. http://tf2glados.dynv6net:8080/LineageRecovery/
Otherwise, just update TWRP. I tried it with the latest TWRP version just now and it works.

Hello, thank you for working on this.
I flashed it yesterday and had an issue with mounting USB to my windows computer.
It worked on the first boot, and I was able to pull down the notification bar and tell it to transfer files. However on subsequent boots it did not give me such an option, although rebooting to recovery with the cable plugged in the same way mounted the device in my computer.

I haven't had any issues with that and I wouldn't consider it a build-specific bug, but I might be able to help you anyway. Plug in the phone, go to developer options and tap on "Select USB Configuration" and set it to MTP. That mostly fixes hiccups with USB modes for me. Otherwise, try replacing the cable if you're using the original Nextbit one that came with it. Mine became really unreliable soon after buying the phone, so I replaced it with a better (USB 3.1, even) cable and now it just works.

Short note here, my Raspi server died on me again, so sorry for the dead links again. Buuut I'll be home soon, so I can get around fixing the Pi and the downloads will be up again just in time for a new build.

Enjoying the new build so far! Pretty good for me.

sm-t800 best rom

Hi guys I have a sm-t800 and the official rom is old and outdated , what's the best Rom to use to bring some more security and speed to the tablet ? And maybe get rid of all the bloatware from Samsung ? Any recommendations ?

It seems like you don't have a whole lot of choices. There is the stock MM 6.0.1 ROM or LineageOS. In my experience, LineageOS ROMs tended to have more visible bugs and hardware support issues, but then I haven't touched LineageOS ROMs for more than a year. You can certainly try both. The stock ROM has lots of bloatware. While you can't delete a lot of the apps, you can at very least try to disable almost all of the superfluous apps that come with the Samsung ROM. This improves the performance (not just CPU, but also battery) and frees up the valuable storage space.

Thanks Akopps I have installed LineageOS and it's nicer without all the Google spy software and Samsung bloatware, installed Aptoide on it for apps and works ok so far. The only thing that seems to be an issue so far is the fingerprint reader

FP Reader never worked for me satisfactory, regardless what ROM. I would also recommend:
[ROM] [AOSP] [7.1.1] [OFFICIAL] LiquidDeathOS - SM-T800 with deathly adiutor + tools on board, in case you are into tweaking. it is the best combination of function+lightweight in my eyes.

LineageOS has been working well for me on my ST-800

I really like this OS and until last week, I've had no issues. I started getting a flashing red board around my screen and response of my bluetooth keyboard has been slow. I ran the latest update but it is still happening. I'm going to check in with LineageOS to see if there is a fix.
