Update rooted SM-T715 - Galaxy Tab S2 Q&A, Help & Troubleshooting

My rooted SM-TT715 is running (stock) Android 5.0.2. When I search for updates in settings, I get a message (analogously) that my device was unauthorized modified. Also SmartSwitch reports no updates for me. What's the best way to upgrade? Is there already an Android 6 out for the T715, or just 5.1?
Thanks a lot!

[Q] [q] samsung galaxy s 5 will not unroot.

Hello,
I have a samsung galxay s 5 running on android 4.4.2. its model number is samsung-sm-g900a. I rooted it 6 months ago but decided to unroot it when the lollipop update came out, so i would be able to get the update. I used odin and downloaded the samsung galaxy s5 stock. I have tried twice to unroot my phone but after i go through the process and download root checker on the play store, i find that my device is still rooted. Any suggestions would be greatly appreciated.

The downgrade to nce file should work fine, ive used it multiple times and been unrooted. You can load the lollipop update prerooted thlugh if you want to do it that way, which a guide for is in general.

I'm running the pre-rooted lollipop on an at&t S5 and works very well. If you unroot and get the official OTA update, you'll be stuck unrooted until someone finds a way to root again.
If you use the pre-rooted file you can go back to KitKat if you don't like the new Lollipop.

SM-G800F - Samsung Galaxy S5 Mini - Update after rooting?

Hello!
Is there a way to update your device through the official updates of Samsung to the newest updaate?
I rooted my phone using the "Root Samsung Galaxy S5 mini SM-G800F using Odin" guide on AndroidMTK. (Search it on google, first link it is probably) but now it says even after unrooting that I have modified files on my phone and making it unable to root.
I want to download the OTA Updates because it contains Android 5.0, doesn't matter if I have to unroot because I don't like my rooted device anyway.
Is there any way?
Please help.

I found that the device will update OTA regardless of root. Root is broken after the update, but that's all.
The message about having a modified system only appears when no update is available. If there is an update, it will start downloading and install.
Others may be able to confirm/deny this behaviour, but that's how it worked for me.

Running rooted 5.1.1, how to upgrade to 5.3.2 for Alexa (5th gen Fire tablet)

Hi! I have a 5th gen Fire tablet running 5.1.1, rooted with the Supertool, lock screen ads turned off.
I'd like to get Alexa. I understand that Alexa is available in firmware 5.3.2.
I see here that 5.3.2 can't be rooted but can be downgraded to 5.3.1, which can be rooted. So I think 5.3.2 is the version that I want, rather than 5.3.2.1, to preserve the option to root in the future.
What is the process to upgrade my tablet to 5.3.2? Based on experience with other devices, I would expect that I'd need to do some combination of unrooting, factory reset, clear data and cache, etc.
But I'm reading the instructions for restoring stock firmware here, it looks like all I need to do is an adb sideload in stock recovery. Is it really that simple? No need to do anything else?
I'm assuming the result of that will be a fresh install of 5.3.2 with Alexa, and then I'll want to use the Supertool to install the Play Store.
Can anyone just provide a quick confirmation that I have this right? Thanks for any help!
5.3.2 isnt rootable, OTA updates will probably be an issue unless you can block auto updates.

Yep. You'll probably want to hold off if retaining root option (and ability to flash a custom ROM) is more important than Alexia. Might also consider grabbing a refurb Fire 7 from Amazon (<$30 USD) and running Alexia on that pup. Best of both worlds...albeit with additional cost and hassle of dealing with 2 devices.
Thanks for the heads up about OTA updates. I figured I could just ignore OTA updates and stay on 5.3.2. But is that not the case? Will Amazon automatically update 5.3.2 to 5.3.2.1 without my approval?
Sorry for the very basic questions. I've been happily running 5.1.1 (rooted, OTA updates disabled by Supertool), so I hadn't considered the problem of a forced update.
Or is there another way to get Alexa (custom ROM, for instance)?
Thanks again!

Yes, it will automatically update as soon as it can. And unfortunately, updates can't be disabled without root, so 5.3.1 is the newest you can safely obtain without locking into the terrible 5.3.2.1 situation we're in now.

how to upgrade from 4.4.2 DynamicKat to 5.0+

Hey guys! I'm tryinig to upgrade to a 5.0 device. I've got several apps that are not supported on 4.4.2.
I'm currently running: DynamicKat 7.1 NH1
Safestrap I've got on here is version 3.75
Baseband says NC2 at the end.
It's the AT&T phone, SM-N900A.
I'm trying to get to 5.0, while still having a rooted phone. I think the only real "feature" I ever used was tethering that the stock image didn't support... as well as a few apps that require root.
I've been looking through forums for a few hours... I keep thinking I find what I need to do, but it's really confusing. I see warnings that "you must be on a 5.0 bootloader!" or "You must be at this baseband!". It seems like I'm not sure which set of instructions I actually need.
Thanks in advance for any help...

How To Prevent Android 10?

It took me a long time but I have finally gotten things settled down and working adequately on my new 405QA with Android 9, root w/Magisk, etc. I read here <https://www.theandroidsoul.com/lg-v40-update/> and elsewhere there may be an Android 10 coming. While for some that may be great news, for me it isn't. I need to rest and recover from the migration from my old Samsung Note 3 with 4.4.2!
So the question is: how do I 100% avoid any new Android OS updates from being (a) downloaded and (b) installed? In developer options, I have turned OFF "automatic system updates". But I fear this is not enough.
On my old Samsung, rooted with SuperSu, this alone seemed to prevent OS updates. But somehow I wonder if using Magisk and all will make preventing updates a bit different. What is the best way to handle this?
Thanks!
So, what you have done already is enough. Also, for a number of carriers you only get OTA if you are with the original firmware so if you cross-flashed your phone to unlocked US kdz, it is unlikely you would get any OTA updates even if you didn't disable in developer options. Any further options, you'd need to be rooted (which you are), disable/freeze both 'Software Update' apps and 'Fota Update' app. Titanium Backup is the best to freeze these.

Thanks. Have not cross-flashed but I have used Magisk debloat to deal with fota and software updater. I feel better/safer now. Cheers
