What is the main thread?

I'm trying to install TWRP on a P585Y, but having no success. Won't boot into TWRP on Android 6.0.1, 7.0 or 8.1. I get thin with and coloured stripes down the length of the screen with a black background.

Thanks.

The only thing is to wait the dev to upgrade your twrp. If you want to root your tablet, just use magisk.
[Samsung Galaxy Tab A series Guides, News, & Discus] funinagg:
going to try it out this weekend now that warranty is over.

do i have to reflash original firmware?

i have not done anything yet so this sm-t580 just has the OTA samsung updates. n no other mod.

any other advice?

the main reason i am doing it to make sd card the default storage where all new apps install. and remain there after any auto update.

adblocking, bloatware removal n generally faster r helpful ofc.

thanks.

Advice=Be Fearless, have fun, be ready to be challenged, learn something, and get things closer to what you want. Hard to brick this hardware. If your goals are to try something, learn something, it is hard to go wrong.

Rooted and running 8.1 I'm having only one difficulty. When the Tablet is on (doing nothing/idle) it won't charge. If I turn it off it charges. I don't get this one. In Developer Settings the USB Configuration stays on MTP even after I tap charge. Anyone got an idea why?
[Samsung Galaxy Tab A series Guides, News, & Discus] funinagg:
thx :) i have sm-t580. tho i did get stuck on first step. as the poster just above me. all i get after flashing twrp via odin is vertical lines. blue then purple then almost nothing. so twrp i used is wrong? i used the one posted in this tread op. tried two older twrp version too. didnt work. also tried booting into twrp with and without cable attached. none worked. now i can not get it to boot normally to OS. plz help.

can i skip twrp all together? if yes then how do i used odin to flash magisk, custom rom and gapps? thx
[Samsung Galaxy Tab A series Guides, News, & Discus] Nimueh:
Install the other TWRP, OMNI6 - or follow my guide HERE. Just replace your wifi version with my lte version when downloading the files. There is a newer OMNI6 out too, you can find it HERE.

It worked for me and I was new to all this Samsung crap, so I'm sure you'll work it out too. Good luck :fingers-crossed: :)

And no, you do need TWRP - but the OMNI6 version works flawlessly :good: :cool:
[Samsung Galaxy Tab A series Guides, News, & Discus] funinagg:
thx again Nimueh. i dont see md5 for those files? ok to install without checking md5?
[Samsung Galaxy Tab A series Guides, News, & Discus] Nimueh:
My device didn't explode and is still running great ... you'll survive :laugh:
[Samsung Galaxy Tab A series Guides, News, & Discus] funinagg:
ha ha. OMNI was a critical piece of information.

i am more comfortable with adb route from pc from nexus and oneplus days. but had some issues there (not 1.0000).

tho it did work ok with sending files to tab from pc. and then installing from OMNI TWRP (got 1.000).

now onto "hi there" screen.

only thing left is to learn how to use both tab storage and sd storage properly. first try failed. when i tried to format card as internal storage it went into a bootloop. took the card out for now. ideally i want apps that shd be fast on internal storage n other that can be slow on card. but if i had to choose one, they wud all be on card becos of more space means more apps
[Samsung Galaxy Tab A series Guides, News, & Discus] Nimueh:
I've never used my SD card as internal simply because that makes it pretty useless. I tend to switch the cards between devices or even use them on my PC and if they're formatted as internal that's no longer possible. But as external my cards have always worked on every rom :)

So I can't help you there, but I'm glad you got the rest sorted :highfive: :)

Having the Right Android Version

In order for this tutorial to work, you must downgrade the version of Android on your device to 7.0 (Android N/Nougat) first. At the time this response was written, TeamWin hasn't developed a working version of TWRP for Android 8.0 (Android O/Oreo) yet.
[Samsung Galaxy Tab A series Guides, News, & Discus] mhd_atzh:
Did you find out any way to only root in only Android 8? And did you upgrade to Android 8?
[Samsung Galaxy Tab A series Guides, News, & Discus] bankheaddaniel:
I didn't find any way that worked [on Android 8]. Downgrading to Android 7 (Nougat/N) was the only [I found] to obtain root access to the device.
[Samsung Galaxy Tab A series Guides, News, & Discus] webzo:
Ok, this is useful information.... Mine is at Android 8.1. How do I downgrade to Android 7?

Also, after the downgrade and TWRP+root, I guess there is no going back to Android 8...
[Samsung Galaxy Tab A series Guides, News, & Discus] starbright_:
Thanks for this very beginner friendly how-to.

What I am wondering is about this that differs from what I used to do:

"e. SuperSU (get latest version) https://download.chainfire.eu/supersu

f. ashxy's Dm-verity and force encryption disabler https://www.androidfilehost.com/?fid=24591000424951049"

For e) I would guess this is only one way to get root. If you install Magisk later one this is not required, right?

About f) - now idea what it is needed for, can someone please explain?

Ongoing saga of my SM-P580 . . .

1st post: couldn't get the install to work. In boot loop, please help. :confused:

2nd post: redownloaded all the files and did reinstall . . . WORKED! Yay!

Today: problem again . . . :rolleyes:

I have a tablet case that will shut off the screen when I close it. When that happens the tablet locks up. Just get a black blank screen. I also can 't power down or restart the tablet using the power button; I end up doing the power/vol down/home key thing. I press and hold them til I get the blue warning screen, then press the down volume to restart. I've been powering down the tablet every time I am finished. Am I missing something? I also got an alert that TWRP app has to be updated . . . ? I haven't found any info about that; I don't want to mess with it cuz I'm sure I would screw things up. :confused::(. Any suggestions would be deeply appreciated. :crying::confused:
[Samsung Galaxy Tab A series Guides, News, & Discus] JR1979:
So I got this all done on my SM-P580 with Android 8.1.0. It boots up fine. I got Magisk in there and running and added the ExSDCard Access Enable module. But I am not seeing my 1218GBB SD card as internal storage. If I try to format the SD card it does not have an option to format it as internal storage. It just refers to it as portable storage. I've looked all over reading about it, trying to figure out what is wrong. Can anyone tell me what I am missing here? Thanks in advance. I really appreciate it!

TWRP restore : failed to mount '/system'

Hello,

I have a Galaxy Tab A 2016 SM-T585

I have used ODIN to flash your [2x1]MOD_SM-T585XXS6CTC3_with_twrp-3.3.1-1-gtaxllte_and_patched_boot_with_disabled+dm-verity,+forced+encryption+disabled_without_CSC : no problem.

I have installed magisk 20.4 : no problem.

I have made a backup : no problem.

Then I tried to restore this backup : it ended with "Failed to mount '/system' (invalid argument)" and "No OS installed".

What should I do ? Thank you for your advice
[Samsung Galaxy Tab A series Guides, News, & Discus] JR1979:
Thanks. I finally got it working a while back. I thought I posted an update but I don't see it. I documented what I did but of course cannot find the document! :( I'm actually currently trying to upgrade to a 400GB card but that's not going well. It seems like the maximum capacity for an SD card on this tablet is 256GB. So I put the 128GBB card back in and now the table wants nothing to do with it either. :(

Dug this tablet out of the drawer to root and ROM for my kids. I've downloaded all the appropriate files and installed the ones that need to be installed. I'm getting stuck trying to install TWRP. I put the tablet into download mode, by holding power, home, and volume down at the same time. I select AP on Odin. Then I push start. I get a log of 0 completed/0 errors. I don't think that Odin is seeing my tablet. What could I have done wrong?

If anyone is still subscribed to this thread I would love some noob help :)

I'm no stranger to rooting and flashing, but haven't bothered recently on my Samsung devices.

But my SM-P585 always runs into storage issues, so my main goal is to try and format my 256gb card as internal storage.

I followed a guide I found that tries to force-enable to the option via ADB, but even though I experienced no errors, it appears to have had no effect on the storage options.

Any advise on how to actually achieve this before I frisbee the tablet out the window?
[Samsung Galaxy Tab A series Guides, News, & Discus] BajaBlast4Life:
Do a trade in to Samsung and buy a new Tab S6 or S7 with 128/256/512 GB of internal storage + mSD card.
[Samsung Galaxy Tab A series Guides, News, & Discus] lewmur:
Do you understand the reason Google stop supporting apps on the SD card? First of all, it is a security risk. But MUCH more important, IMO, is that the SD card is very, very slow compared to the internal RAM, physically attached to the SoC. If you root the tablet and do a serious debloat of the apps and make sure all of the DATA is transferred to the SD card, then you shouldn't have a problem of running out of internal storage. The only exception to this that I have seen is games that stupidly insist on their DATA, not just the app itself, be stored in internal memory. Personally, I have no sympathy for people who buy a tablet and expect it to be a highend gaming device.
[Samsung Galaxy Tab A series Guides, News, & Discus] PRGS3:
I mostly use the tablet for reading and browsing, so I would have hoped that the speed issues wouldn't impact me that much.

That said, I reckon I'll go the root and de-bloat option (assume via Titanium?) and see where that gets me before I embark on the internal storage route.

In the event I do, is it still possible on 8.1 or do I need to downgrade to 7?
[Samsung Galaxy Tab A series Guides, News, & Discus] BajaBlast4Life:
It takes like 15 minutes to open an app if you use a slow m-SD card and about 3 minutes with a fast 90 mb/s read & write m-SD card.

You're better off with flashing a debloated Stock rom (if it exists for your model). I have the one with the S pen, the original Samsung rom left me with about 2 GB of free space. The debloated rom left me with over 10 GB of free space!

You have to downgrade to Android 7.0 in order to flash TWRP and root. You can do it on Android 8.0/8.1, but you get a black screen after TWRP on the device. It's very difficult to get out of the black screen because you can't see what's there. You have to know what you're doing in order to get it to work on Android 8.
[Samsung Galaxy Tab A series Guides, News, & Discus] PRGS3:
I don't mind downgrading to 7 because I really only use the tablet for basic stuff.

But...where do I find a debloated stock rom? I also have the S Pen model (P585)...if same as yours do you still have a link to where you downloaded it?
[Samsung Galaxy Tab A series Guides, News, & Discus] mordantly:
Last I checked, there were no aosp based roms with s pen support. I'm still on a debloated deodexed N rom.
[Samsung Galaxy Tab A series Guides, News, & Discus] klaberte:
I too am a fan of AOSP, but the S Pen is what I needed. So, while I would have preferred someone doing the work of creating a ROM for this Tab, what I ended up with was Stock ROM with root, which allowed me to freeze or remove whatever I wanted. I also tried a few launchers, until the unit felt fairly de-Samsung-ified. And with perfect S Pen support. (I still strongly endorse using Write 3.)

My suggestion would be to read and try a few debloating posts.
[Samsung Galaxy Tab A series Guides, News, & Discus] BajaBlast4Life:
I don't remember, since I flashed it back to the stock rom and was going to give it away to someone, but they changed their mind.

[Samsung Galaxy Tab A series Guides, News, & Discus] klaberte:
From my memory, the only steps that should be computer OS specific are those that provide the proper USB drivers for Samsung devices and using a tool to flash specific software (ROM, TWRP) onto the tablet. I'm sure there are good options, perhaps even the one you suggested.

Just checking in to report this is still valid in 2023. Installed flawlessly on a *No OS* sm-t580 (2106) using

T580UESSCTL1 (XAR) (android 8.1)

TWRP 3.7.0_9.0 gtaxlwifi (current at time of reply)

SuperSU (as linked in OP)

No-verity-no-encrypt_ashyx.zip (as linked in OP)

Installed error free in one pass *ONCE I USED ODIN 3.13.1* Using Odin 3.13 is a must due to the format the firmware was compressed with or something like that (yeah not using it is a deal breaker, ODIN 3.12 just hung for almost 20 min. asked google why, updated, and down the road we went...) A development that came well after this guide was authored i'm sure.

This is a really good tutorial. Many thanks. But all these years later I must ask how does one back the tablet up before starting?

I ask because my data partition is not mounted and showing 0mb. Obviously I could wipe the data partition(TWRT is installed) as a solution but then how would it it be a nandroid backup?

Perhaps I'm not seeing something here any advice appreciated .

Thanks
[Samsung Galaxy Tab A series Guides, News, & Discus] cliffhanger54:
Does anyone have a solution or am I a complete noob? I need to root a sm-t580 but must backup before beginning or at least that's the advice.

How can one when I can't mount data - because of encryption? Use Helium? That looks deprecated. Advice?

Thanks
[Samsung Galaxy Tab A series Guides, News, & Discus] Uluru25:
1. some custom recoveries support encryption of /data partition (but personally I wouldn't try to get a data backup via the recovery)

2. save all (personal) data when the ROM is booted (to the external SD-card or to your PC)

3. if you want to save also apps and their data, you could try tools like Migrate.

[Samsung Galaxy Tab A series Guides, News, & Discus] klaberte:
Perhaps I'll add this to the guide. Formatting an SD card in an android device before using in said device is a good general practice.
[Samsung Galaxy Tab A series Guides, News, & Discus] klaberte:
How so? I'd be interested in hearing your experiences.
[Samsung Galaxy Tab A series Guides, News, & Discus] the gladiator:
I believe you’re referring to the second point as the first point is a technicality.

I never had a Samsung smartphone/tablet (and, probably, for this reason I'll never have); I'm only telling what I keep on reading on many Italian forums. Unfortunately!
[Samsung Galaxy Tab A series Guides, News, & Discus] Tromatic:
Thanks very much! THIS is the sort of simple guide that keeps dopes like me out of trouble. I would add on thing, though. For some reason (something I did)

I had tripped the FRP boot protection and the tablet would not boot. After flashing the stock ROM and booting to the start screen then rebooting to flash TWRP the flash was blocked again by the FRP protection. I had to go through the process to sign in with google before it would let me continue. Perhaps you could add that as a fix or troubleshooting guide if someone has a similar problem.

Does that make sense?
[Samsung Galaxy Tab A series Guides, News, & Discus] klaberte:
Yes, you are right. The second point.

Of course it is your choice, but you will have to weigh the likelihood of needing warranty support vs the advantages of root and recovery. Like I said, Odin makes it quite unlikely that you will break your tablet via software or configuration. Odin offers a "back to factory" option that I wish all brands offered.
[Samsung Galaxy Tab A series Guides, News, & Discus] klaberte:
I'm happy to add some instructions on FRP locks, but honestly I've never encountered them. It seems like you would want to disable them in step 2b. If you can find some instructions, please let me know and I'll add them.
[Samsung Galaxy Tab A series Guides, News, & Discus] Alex_the_boy:
Hello guys,

How about future FOT updates? Will they come after custom recovery and root installed?

If so, should I install TWRP and root again after each update?

Ah, forgot one thing, I've installed twrp-3.1.0-0-gtanotexlwifi.img.tar the newer version. Is this ok?
[Samsung Galaxy Tab A series Guides, News, & Discus] klaberte:
Sorry for the delay. In general, any kind of messing with recoveries, rooting, etc. has the chance to break over the air updates. However, xda is usually pretty fast at incorporating the updates that come from the manufacturers or Google. You just need to look for your preferred ROM's thread to update to the latest and greatest.

If it is just a ROM update, see the instructions of 7a. It is also a good idea to wipe the Cache and Dalvik Cache whenever you make any change; they get rebuilt as soon as they are needed.
