It's 7.0 out of the box, and it's WiFi security patch, device stability improvements, new or enhanced features, and further improvements to performance. I'm assuming it's stuff that won't affect rooting/TWRP in any way, but it doesn't hurt to ask, ya know?:)

Alrighty I think I did it with no problems at all, MB are not zero and everything looks good so far! Will have to check it out more after work to make sure though. Also, I've been seeing that Netflix won't work with this but only with Magisk?

I've moved a number of apps on my T580, from internal storage to external SD card.

What happens to those apps, if I restore a backup made with TWRP?

Will the device boot fine, but I'll have to either delete or re-install those apps?

Any selection in TWRP that I can make, to backup the apps I've put on external SD?
[Samsung Galaxy Tab A series Guides, News, & Discus] lewmur:
I can understand putting audio, video and photos on external sd, but why apps? The internal storage is magnitudes faster than external and even with a 16gb device there is plenty of space available for them. The only way I know of that space becomes a problem on internal storage is if you make the mistake of putting your backups there or store HD movies on internal.

I know "apps2sd" was a lifesaver on an old 4gb tablet, and the first thing you did in setting one up was to move everything you could to the SD. But on a 16gb or above? Why????? :confused:
[Samsung Galaxy Tab A series Guides, News, & Discus] stonypass:
Probably should have said "Games" as that's what I moved.

A number of the racing games are 2-4gb each once you get additional tracks etc downloaded.

Newbie here and in need of some tutorials with questions answered:

Is there a way to do this and do Root External 2 Internal SD? My internal storage is basically full. I'll do the adoptable storage thing as a last resort. But I'm not really sure how to do that. I'm pretty sure the tablet needs to be rooted to do that, (I know it needs to be rooted for the root external thing) because format to internal doesn't show in the settings of the external sd card. And is XInternalSD basically the same thing as Root External to Internal.

Guys i have question after i rooted my devise can i uss the reset to factory settings? Should i run into any trouble?

---------- Post added at 08:06 AM ---------- Previous post was at 07:37 AM ----------

Also how can i unroot and remove the twrp?
[Samsung Galaxy Tab A series Guides, News, & Discus] scoobysnack:
This tut would have saved me a ton of time. I tired 2 tablets then soft bricked one installing TWRP. I could not get root no matter what I tried. I got the idea to formate the dates to see if that would clear the errors, that did the trick. If I would have used the search function I could have saved 3 hours :)

Hello!

New to Samsung devices here! I've been reading the OP guide but I prefer Magisk over SuperSU. Am I right to infer that I just need to flash the magisk package and not SuperSU in step 5? Do I still need to flash no-verify?

Thanks!
[Samsung Galaxy Tab A series Guides, News, & Discus] flroots:
I performed the steps indicated by the OP on my T580 and it worked fine except that after rooting I now have a 6-9 second delay after entering the security pattern. That delay did not exist prior to rooting. I tried all steps using superSu v2.82 and v2.79 with same results. Any ideas what's happening? BTW, I get the same delay when using PIN and password security.
[Samsung Galaxy Tab A series Guides, News, & Discus] krakout:
So I tried to follow the guide, but got stuck at 5a. In short, switching from Down+Home+Power to Up+Home+Power doesn't seem to do anything, the device always boot into the white-on-black screen with "Galaxy Tab A" on it...

T580 with 7.0, tried both TWRP 3.0.2.0 as in the guide, and 3.2.1.0.

Any help, anyone?

Thanks!

[EDIT] Seems like I fixed it by flashing twrp-3.2.1-0-gtaxlwifi.img.tar, not gtanotexlwifi? Still rebooting though, we'll see...
[Samsung Galaxy Tab A series Guides, News, & Discus] klaberte:
Yes, just install Magisk in step 5g, as directed in https://xdaforums.com/showpost.php?p=73719123&postcount=82

I believe that no-verity is still required.
[Samsung Galaxy Tab A series Guides, News, & Discus] krakout:
Thanks, I just did. And from reading around what no-verity is required (to disable re-encrypt on each boot?) I decided to go ahead and flashed that, too. I didn't get Magisk Manager when it finally booted, I thought it came with the flashable zip? Anyhow, gonna hunt the apk now :) [EDIT] no, it's there, I just didn't see it :D :D

Thanks again!
[Samsung Galaxy Tab A series Guides, News, & Discus] opasx:
thank you so much for the step by step approach, while I am not a complete idiot, I needed it explained simply and it worked first time.

also with twrp and the swipe issues, I learned many tablets ago that just sloooooowly dragging your finger across (giving the slider to catch up to the fingers position) works every time.
[Samsung Galaxy Tab A series Guides, News, & Discus] opasx:
weird issue, unsure if it's known or just me, I can not access sd cards from apps but included file browser and twrp both see it fine. I thought I might have received some dodgy cards but they all work on PC, phone, other tablets, I went back to stock rom and sure enough all work. I might not be searching for the right terms, so all help is hugely appreciateed.
[Samsung Galaxy Tab A series Guides, News, & Discus] JeepinxJosh:
This has happened to me also... it happened when I rooted my J7 also... both used ashyx no verify and su method through twrp... I did end up fixing it on my J7 but for the life of me I can't remember how.... I think I ended up re flashing some part of the rom/firmware but I can't remember exactly... has anyone else figured it out? I know they did in the J7 prex threads I just can't find it lol....

But this seems to be a common problem... and I have yet to see one answer on here...
[Samsung Galaxy Tab A series Guides, News, & Discus] stonypass:
I believe that's due to some versions of superSU, search this thread for details as it's mentioned in it numerous times. I'm running that ROM btw, and I highly recommend it.

I was all set to root my new tab a, but honestly, I'm not spending 9 hours to download something I can download in 12 seconds, just to give some ****s 12 bucks. I'd rather just ignore the ****ing ads.
[Samsung Galaxy Tab A series Guides, News, & Discus] JeepinxJosh:
I put it on and loved it all the customization was great especially when you add magisk instead of Supersu. I would have kept it but he got rid of the Samsung account option and I can't even manually install it.. well it installs but the rom ****s it down so it won't open... I use my Samsung account for backup and settings and a lot of stuff... so I tried ultra slim... good rom too... still no Samsung account option. I guess I'm either gonna have to go back to stock and use some debloater by myself since magisk has some cool modules I think thats the way I'll go...

And fyi... since swapping magisk in I didn't have to use supersu or the no-verity script and I got no lag delay at all....

---------- Post added at 01:36 AM ---------- Previous post was at 01:33 AM ----------

No magisk will do all that for you.... just make sure you flash it before you boot up or you get forced encryption and will have to start all over... I just did this and magisk is deffinitly the way to go. No lock screen lag

hi i have samsung smp585 and i did every thing but now my tablet is not going past the reboot it been an hour what do i do
[Samsung Galaxy Tab A series Guides, News, & Discus] Winston Churchill:
Thanks for the tutorial.

I'm actually on the Galaxy Tab A 8.0 inch T380....but this was very helpful to a newbie to TWRP. The tutorials online here for my model were crappy and landed me a) first with being unable to flash TWRP and b) only official binary error.

I got a response that I shouldn't follow third party tutorials and instead should follow the TWRP tutorial for the model. I said I did, it's the one you wrote and in EVERY. SINGLE. STEP you got the button options wrong. Literally EVERY COMBO. So this one helped me get it right.

Because the TWRP for my model (or any) tutorial didn't include the March 2018 security updates, I then got "only official binaries allowed"... error on reboot. And there it stayed!

What I had to do on my T380 (which I only recently got - not a 10 inch, the 8 inch Tab A) - it might help if these updates have been rolled out to your 10 inch devices earlier this year and you find yourself stuck on the "official binaries" error.

If you have that error, flash stock ROM again.

Unlock Developer Options

Wait 7 days again for OEM unlock to appear in the Dev Options menu

Flash TWRP etc.

Once you've set up your tablet again YOU CAN'T REBOOT IT FOR ANOTHER 7 DAYS until OEM unlock shows up again or else you'll get that "official binaries" error.

Also did the following mods to my system in ES FIle Explorer while waiting out the 7 days to do my first reboot since root:

>Find the file build.prop. Find the setting ro.security.vaultkeeper.feature=1 (browser or text search). Change the value from 1 to 0. Then save the file.

>Next, delete the RLC folder found in /system/priv-app/Rlc

Thanks for the help.

Question about SuperSU

Is SuperSu actually required to be installed for TWRP to work and/or to have a custom ROM?

I am using AndroidPay/Samsung Pay on my devices and I do not want to loose that functionality by having the device rooted... So can I skip installing superSU?

Thanks!
[Samsung Galaxy Tab A series Guides, News, & Discus] lewmur:
No, it isn't necessary to root your tablet to use TWRP and custom ROMs. Though a few ROMs do have builtin rooting. If they do, they'll give you a way to remove it.
[Samsung Galaxy Tab A series Guides, News, & Discus] Quoddity:
unlock bootloader

This is a excellent guide, I'm just wanting a slight clarification surrounding the bootloader.

I've only unlocked 3 android devices, and I've always used adb/fastboot to unlock the bootloader and install TWRP.

This guide mentions only enabling "OEM unlock" in the settings: is this how you unlock the bootloader in these devices? I don't know why, LOL, but I am expecting more steps.

Do I need to also do the typical "fastboot oem unlock" via a terminal command?

I have an SM T-580.
[Samsung Galaxy Tab A series Guides, News, & Discus] klaberte:
Thanks Quoddity.

No need to use fastboot oem unlock, and just making the change to OEM unlock in the developer settings is all that is needed to unlock the device.

I prefer to use ODIN, as it is the go-to tool for working with Samsung devices, especially for installing base firmware and specific partitions (e.g. recovery). It is because of ODIN that Samsung devices have the reputation as "hard to brick". No matter how much you messed up your Samsung, all you need to do is get the device into download mode (using the key combination) and re-writing the whole device firmware with ODIN. While this will not reset the Knox, it will put the device essentially into factory reset condition. There may be other tools that accomplish this, but ODIN has yet to fail me.

Getting original firmware from updato is easy, but will take a long time (for me, up to 12 hours), so it is a good thing to get "before you need it".

Let us know how this whole thing works for you. Just make sure you have the right model number for both your firmware and TWRP. I'll be interested in hearing your outcome.
[Samsung Galaxy Tab A series Guides, News, & Discus] milaremi:
I'm guessing that the most current retail versions of the Wifi Tab A (10.1) (2016) have some kind of kernel rework that's blocking TWRP from loading via the ODIN method. I've been at this for 2 days now on the tablet I just purchased at Costco and I've followed this guide religiously (Thank you for posting it)!

Once ODIN installs TWRP (3.2.3.0) successfully and I move on to section 5, - PWR+HOME+VOL_DOWN, then immediately +VOL_UP at the blank screen - the tablet goes into some strange blue stripes and then transitions to red/yellow artifact lines and locks up. Only a reinstall of the original firmware (again via ODIN) gets me back to stock but multiple attempts at various TWRP versions has so far been unsuccessful...sigh.

Any input or insights would be greatly appreciated!
[Samsung Galaxy Tab A series Guides, News, & Discus] Quoddity:
thank you for your kind reply.

Just a follow up question:

I have the SM-T580, as stated in my settings.

But at the firmware site: "desktop.firmware.mobi", it gives two different devices for my model and I cannot seem to see the difference in my settings.

For SM-T580, i get:

gtaxlwifixx	gtaxlwifi

gtaxlwifizc	gtaxlwifichn

Is one US and the rest International or something like that?

I'm in Canada, if that helps.
[Samsung Galaxy Tab A series Guides, News, & Discus] klaberte:
What specific tablet model do you have (Settings->About Tablet)?

This sounds like a deeper issue with TWRP, as opposed to an issue with the guide. I suggest, once you find your tablet model, you go to:

https://xdaforums.com/galaxy-tab-a/development

and search for the official TWRP thread there.

[Samsung Galaxy Tab A series Guides, News, & Discus] Quoddity:
This worked great and took very little time! Thank you!

I have one issue though:

SafetyNet did not pass.

(I have root)

I imagine it is the custom ROM, but the I just want to ask, is the no-verity file up-to-date as specified in 1f?

Just so it's clear, I didn't flash the firmware (optional step 3), and I installed the "lineage-15.1-20180501-UNOFFICIAL-gtaxlwifi" custom ROM (before Magisk)

Then at 5g, I installed the latest Magisk instead of SuperSU, and afterwards, I installed the no-verity file as indicated in 1f.

I have already tried reinstalling Magisk and then the no-verity again, but there was no change.

thanks again.
[Samsung Galaxy Tab A series Guides, News, & Discus] klaberte:
Odds are your issues aren't with the guide, but with compatibility with your ROM. As such, you would likely get more traction on threads devoted to your particular ROM.

If you want to do some troubleshooting here, please clarify if not passing safety net is actually causing actual issues. Are you able to use apps that usually do not work if root is detected? Have you configured Magisk with Magisk Hide and Core only?

Also, please consider retrying the setup, but with the original stock ROM (not a developer ROM). If things work in that case, then you can decide which path is more promising (sticking with the stock ROM or working to clear up any issues with your preferred ROM).

In any case, please come back and let us know how things resolve for you, as it will likely be helpful to future readers.
[Samsung Galaxy Tab A series Guides, News, & Discus] Quoddity:
Since this thread is for the Guide, I will simply state again that it worked great, and many thanks for it.

My issue had nothing to do with the Guide.

I was able to get my device working more fully with a different ROM & different open_GApps.

(RR-O-v6.1.0-20180815-gtaxlwifi-Unofficial & open_gapps-arm-8.1-nano-20180829)

SafetyNet still does not pass, but my error message apparently has something to do with Magisk right now; and, I can make purchases, so... it's really not an issue for me.

Also, the no-verity file in 1f (5h) worked fine. I can add that some apps will not gain root access without flashing the no-verity file as described in 5h. (for me, Titanium Backup wouldn't work without it, but a root detector did.)

Hey Guys,

I am really struggling to find a TWRP image that works on SM-T585 (Non S-Pen, LTE variant).

Any that I try end up with the same outcome - when I boot into recovery I think it boots ok (I can communicate with it over ADB) but the display is scrambled/just vertical lines).

It's not a physical display problem as the display works fine when booting to system.

So far I have tried various versions of the gtaxlwifi twrp, some versions i found on this forum supposedly for the T585 variant, but so far none of them work.

I'm beginning to wonder if I am doing something wrong. Any help is much appreciated :)
[Samsung Galaxy Tab A series Guides, News, & Discus] milaremi:
Hi there. If you've got a recent iteration of your SM-T585 with (probably) the latest firmware from Samsung, check out this thread:

https://xdaforums.com/galaxy-tab-a/...fficial-twrp-gtaxlwifi-galaxy-t3437666/page29

The graphical artifacts are a telltale sign of recent firmware not meshing with the latest TWRP. Many of us with the latest releases of these tablets are waiting for a TWRP fix from *Ashyx*. Once that new TWRP mod has been released (based on the latest Samsung firmware), come back to this thread and try again. This guide is rock solid.

Good luck and please let everyone know when/if it works!

Hi,

and has stopped there for well over an hour. What recourse do I have when this happens?
[Samsung Galaxy Tab A series Guides, News, & Discus] klaberte:
This suggests a problem with odin, or a mismatch of the twrp software with your model tablet. Please confirm whether you can odin other firmware with you computer. Can you flash original firmware in step 3?
[Samsung Galaxy Tab A series Guides, News, & Discus] mr_sprinklzzz:
I did do step 3, and I flashed the firmware. Quick question: when you say original firmware does that mean I should grab the earliest version of the firmware available? Because I think I grabbed the lastest version instead.

Hi again!

I successfully rooted my device after a little trouble (mostly do to not following the instructions carefully enough).

However I have a problem. Ultimately the point of rooting this device was to get Viper4android working, however after trying and failing, and doing some research it seems as though Magisk might be a better option over SuperSU.

I uninstalled SuperSU via it's app, however when attempting to flash Magisk via TWRP it gives me an error. This might be because I might not have clicked yes on the "restore stock boot image" options when unrooting SuperSU.

Do you have any experience switching between root tools, or any insight into why Magisk is failing?

Thanks again!
