Rooting and Fixing Samsung Galaxy Tab E (SM-T560NU) (and fixing -504 issue)

Disclaimer: I know this should go in the correct subforum for my device, but I'm having trouble navigating this site, altogether. I only see subforums for a handful of devices. So if there is a better place for this thread, I apologize
Oh, where to begin. My wonderful girlfriend got me this tablet back in october, since i said it'd be nice to have a linux based tablet so i wouldn't have apple telling me what i can and cannot do with my device (she saw that as a hint, even though it was more social commentary, but I'll take it). Anyway, I found the 16GB limitation problematic, so I decided to root it so i could use some sort of sshfs app to create a slow multi-terabyte harddrive space to steam small files (like music) from. Seeing as i had the thing for only a week and it's kind of expensive, even for a nurse, to buy for me, i chickened out and made due with a small 8GB microSD card which i just happened to have laying around.
Fast forward to a few days ago, I ordered from Amazon a 128GB microSD card (also from samsung), and decided to try to make due with that. Only to find out (and, if you're able to help me you've probably met the following issues yourselves) that the seemingly largest apps refuse to let you move them to external storage. Even better, there's some apps like Star Wars KOTOR (2.5GB) that say they let you move them, but in reality they stay on internal storage and create empty folders on the external medium. And then many apps cannot write and read to and from SD cards (like DOSbox Turbo), for reasons that completely stump me (which leads to me having to move dos games back and forth when i want to play one that saves). I then read about this wonderful feature called "Adoptable Storage," and promptly go through all sorts of things to try to enable it, only to find out that, since I have Android Version 6.0.1 from Samsung, that feature was disabled by them. After using the email support to berate them (they don't have a suggestion box), decided to try to come here and figure out how to properly root this device and figure out how to solve my space issue (I have 128GB of space that I need to use, but have no idea how to use it for what i need to use it for). By the way, a small shoutout to Samsung support, despite my very terse response, there clearly was a human being at the other end and this human was very, very civil and said that they'll pass it on as feedback (I got the impression that the employee either had the same issue or at least wanted me to know that there have been alot of complaints about this issue).
Anyway, now that that wall of text is over, this is how far i've gotten.
I know that XDA is reliable, they've had problems in the past with malware, but it was unintentional and the ship has been cleaned. I don't know about anywhere else, so the rooting instructions i find elsewhere i assume are probably correct, but i don't know where to get files for the process that i can trust, outside of XDA (and i'm having trouble finding the files i need, here).
I have a nice little article from techbeasts.com ( techbeasts.com/install-twrp-and-root-samsung-galaxy-tab-e/ ), but I don't know where their downloads came from and how many people checked them out for windows and android trojans and such.
So...
1. Is that article accurate for android 6.0.1?
2. Are those files safe (free from corruption and viruses)?
3. If they're not safe, where can I get safe files?
4. I like to develop programs, and I want to be able to develop apps for android as well. Once rooted, how does one test how their app would work on an unrooted device to ensure the app follows the "proper procedures?"
5. How do I deal with apps that are root sensitive? The point of all this is so that I can keep using my apps, so if they all break because i'm rooted that defeats the purpose.
6. Other than having to be careful with what i do (I've used Linux for years, and I occasionally like to code in assembly), that it voids my warranty, and that screwing up can make for a really bad day, is there anything else that I should know? This is, indeed, my first touch screen device outside of Nintendo products, because my V3xi is fine for me as a phone.
EDIT:
7. Forgot the most important question: How would I go about getting adoptable storage working on this device once it is rooted?
Forward: Given the nature of my question, the URL is absolutely necessary. After I've gotten my "10 useful posts" I'll fix the URL for future viewers.
EDIT2: Decided to take a chance. Ran into some issues finding the "stock firmware" which I ended up having to do. For those that have problem getting TWRP to stick, you gotta flash the stock firmware of the version you have currently installed. I tried to flash the original that it came with, which, for some reason, it didn't like at all.
Oh, and don't turn off OEM mode after everything's done. I assumed that after everything was installed it wouldn't second guess it and i could safely turn it off for added security if any app went rogue or something. Nope, must keep it on, so do regular backups. Turn off auto-updating, etc. I hear there's some sort of app that lets you "update safely." Not sure what it is, but unless you *NEED* it, don't do it.
And as a bonus note (so it shows up in the archives), some apps didn't install right (either google or the app developer's fault, but these apps weren't tied to this process [pokemon go and just about all the final fantasy games]). The kicker about this is is that you will not notice this UNTIL you uninstall the app, and reinstall it. Deleting the data before uninstalling the app will make it unstable. To find the data, i used
Code:
du / | grep "pokemon" > pokesearch.log
, since i knew that there should not have been a pokemon related directory on my droid at the time, since i needed to reinstall pokemon go because it was acting really fruity. Deleting the folders (actually, the last entry contains the rest, so it's easier just to delete the last one) allowed me to avoid the -504 issue (not to be confused with 504).
Code:
[email protected]:/data/data/com.termux/files/home # cat pokesearch.log

We can talk here for the benefit of the community. Any problems you might have should be documented for the sake of the community. But, yes, the -504 error i mentioned above can only be solved through root, so, yes, i was successful.

Tablet just updated itself after I tried to root it .. MM 7.0.1 but I didnt ask it to

I disabled automatic updates (from settings and google play, 'cause it's in both places) to prevent this problem. There might be a new firmware for the tablet, but i'm sticking to this version. I'm not sure you can downgrade after you upgrade, though. You can take a shot, though, if you're not afraid of loosing data. I doubt this process will brick as long as you can get the official firm ware on backup incase something goes wrong.

Now it seems impossible to root without pc

What is com.android.cts.priv.ctsshim?

After playing around with AR for all trying to get AR+ on Pokemon go and eventually giving up I'm curious on what this app is on my phone? Couldn't find a answer from a quick Google so I guess here is the next best thing.
Kinda of scared to give it root permissions as it's name doesn't sound familiar to any app I have installed. Any advice?

It's a system app that is present on many Android devices, including our Axon 7. You will find it in pretty much any ROM you flash, stock or custom. I don't know what it is or what it does, but it's not dangerous, don't mess with it. It shouldn't be asking for root permissions, that does sound a bit fishy. You may have recently installed an app that is masquerading under this name and now wants root access. Don't grant it. I would look more deeply into what you've installed to see if any of it might be malicious.

I agree with the user above. Its weird that it even has the possibility to be granted root permission. If its a system process, it should already have all the necessary permissions it needs.
Oh btw. I think for AR+ in pogo you need ARCore by google. Our device is not officially supported yet. But since there is cam2 api in oreo, that might change in the future and google could very well add it to the list of supported devices.

look. Download MagiskHide props config module, change the fingerprint to Pixel 2 XL, then download ARCore from apkmirror. It'll work, I just don't know if it works with pokemon go.
I used Measure and Lens (don't know if lens needs it tho)

Thanks man, at first safety net was being hit but a quick reboot later and now everything is working fine. I'm going to do more research into what this is. As I'm sure I haven't downloaded any suspicious apps.

Ok so after some testing it seems like AR Core 1.5 works but is unstable asf, and ARcore 1.4(latest) does not work as the app must be using 1.5 only, it comes up with the "This device is not supported" but seeing that safety is working fine, i assume its looking at the ARCore and seeing its not running on a "supported device" although it does work on 1.5 (sometimes, if im not taken straight to "Not Supported"). Not too sure about this magisk module tho as some reboots come up with a negative safety net

Found on internets:
"The CTS (Compatibility Test Suite) shim is a package that resides on a device's /system partition in order to verify certain upgrade scenarios. This is intended to facilitate the compatibility test that vendors run to ensure their hardware will be compatible with the Android OS. "

@evilKabab: if what you're saying is true, then I'm considering deleting this app from my phone. I generally don't use GApps, and don't care about SafetyNet. Thanks for the info.

its a shimmy hackers tool.
used to encrouch in space.
my ex and his circle are remotely damaging all aspects of my life personal and professional family and financial.
they have pop ups stating i cant use messages internet apps socialmedia or ANY thing that uses data or space urging me to delete files or apps as soon as i do, it encrouches and takes up that space.
ive got an s10 started with 13 pages of apps 1500 svreenshots and 900 photos and crap tons of vids
after a couple months of this i am left with 3 pages of apps (mostly factory apps) and no space for photos
and it still urges me to delete.
this is because i have evidence of too much on my phone

Same here I have 1000s of files and screen shots an pencil an paper notes

Galaxy Core Prime LTE (SM-G360F) How for can i get android?

Hi
New here so dont kill me yet
My bank decided that their wallet app now for some reason need 6.0 as the minimum so my stock 5.0.2 does no longer qualify
bye bye google pay which was a much used one for me, so i wonder if can root/jailbreak (whatever the term is) and get at least 6.0 ?
anything past that is just a bonus
and if i could get rid of the all the bloatware would be nice
my only concerns are if the phone and sms apps are there and the play store

is not something about that a stock android that have not been modded by the phone maker looks very "slim" and "shaved" ?
i would not mind that

i even tried to root the damm phone so i could at least try to spoof the android version, all guides using the cf-auto root and odin failed, and all the guides says the same thing but uses slightly different version of odin
getting to download mode is easy enough and enable developer mode and usb debugging is also not a problem
yet it fails at the very start of the file transfer, so i guess i can just give the bank the middle finger salute and uninstall gpay and their wallet app
strange enough their app for transfering money and paying bills etc do not require android 6, nor does the gpay app, and yet they insist that requiring 6.0 for their wallet app makes it sooo much more stable and secure
morale so far: do not reformat or update apps unless you are forced to with your arm twisted to the back

Google Device

My OnePlus 6T has recently been detected as a Huawei P20 Pro, o would like to know if there's is any file in my device that might be modified to be displaying the right information (Sorry for bad English)

Quick update to this issue, the module "SafetyPatch v3" was the issue, not sure what causes to change the device

The goal of this module is literally to change the phone ID, to enable Play store services to give clearance to the device and to consider it as a valid registered phone in Google database (to pass Safetynet and Google Pay controls)
There should be instructions in the module description to change the phone ID. Or simply remove the module as it's probably not necessary to run it.
Considering the fact that it's nearly a one year old module without any update I think you really should remove it.

I have it disabled, but I downloaded because my device fails the cts profile test and I don't know if it has any impact with any app in my device

Use this one
Magiskhide props config
Well maintained, completely tunable even if it seems more complicated at first glance

I'm gonna check it right now, thanks!

why developers are not focusing more in sailfishOS?

I was just wondering why sailfishOS has still really bad apps.
and why is not developers are doing more apps for this amazing OS?
just wondering

it's very simple: no market.
In general you make apps to earn money. perhaps you'll find some developer or group of developers that will port a popular app as a hobby, student project, or simply because they are using sailfish and want an specific app.
so basically, if there is no market, there is no money. therefore no apps

Actually I have just bought xperia 10 plus to move away from toxic android ecosystem (from google to all the app junk), after I have figured out that I could delete 90% of application on my android phone and I would never miss them.
If you are using sailfish phone, you have an option to run apks there is no real need for native applications. Quite frankly in last few years I could hardly find any application that was something that "I have to have". All the really needed applications were added to the first smartphones: email, gps, browser, sms, mms, calls, video player, music player, camera, contacts, text editor, sound recording... and I am already stretching it with last two, I cant remember when I have last time wrote high volume of text on those tiny useless on screen keyboard or had a need to record some sound.
There is one app on android which I will need (access to online banking) and I hope it will work, it didnt work even on my previous android until I have reversed it and change some code to stop verifying for root and safetynet, so it should work here too.
Everything else is... more a toy than useful or actually some security application to prevent all others doing something that you don't want, from rolling ads to stealing data. I am waiting for this mobile application market to slowly collapse, there is no more value in it except maybe games. Everything else is just wasting time in the least constructive way.
And not having market is a huge bonus, if you check sailfish apps (jolla store and openrepos) you will find that you have everything you need for having a great phone, made by enthusiasts not people that want to become rich. And no one is making useless junk as, as valthunder said, there is no market. And this is fine. Actually great.

Great to read about your decision!
For banking apps that require Google Services you could try to tweak your Sailfish Alien Dalvik with Signature Spoofing and a GServices replacement like MicroG.
The SafetyNet replacement here is the DroidGuard Helper that should be installed alongside GmsCore.

Naah, I am having my own "cracked" apk build from previous phone, I have removed all checks to root and safetynet and it works fine, no need to change it. Since the app is just front end for web interface it works since forever, I have also removed version matching with server. Took a day or two but worth it
But I have one question: I am trying to integrate xposed framework (last version as there si no boot/recovery img to try with magisk) into system.img (8.1). And same goes for su. Is there any "official" way how to do it without unpacking system.img, adding binaries, repacking it...

Following all things sfos quite closely i did not witness anyone get xposed framework to work. (at least no public report) That might be due to sfos users generally are not Android wizards. The matter might still be a low hanging fruit to anyone with deeper knowledge
Whenever rooting/xposed/su is brought up, much more competent guys then me hint at Alien Dalvik just being an AOSP tailored to run inside LXC on non android kernel plus filesystem integration, Intents integration, shared clipboard etc.
quoting my friend olf:
"Jolla uses many modern measures to confine the Android container: at LXC level, with cgroups, firewall rules, SElinux policies etc.
You may configure additional measures at all these levels, it is just a Linux machine and you are the administrator!"
So maybe what you want to achieve practically is even possible using a whole set of different tools then available in Android?
And yes, my vague explanation hinting at me being a simple user having no clue and just putting things together from forum posts is a correct observation
