Hi, try this.....depend of the version of Android​ your use...

Recovery for T580 Wifi (Android​ 7.0) Nougat:

https://www.file-upload.com/htol8nltkhol

OR

Recovery for T580 Wifi (Android 8.1) Oreo:

https://www.file-upload.com/fanzem7veprz

You need to use the v3.13.1 of Odin and flash recovery in the AP field.

What I did was I pushed via Odin the newest TWRP with out reboot then force it into recover with physical buttons... Then I completely wiped every partition then flashed newest October Oreo.[/QUOTE]

Did not work. stuck at step 9 as described.

Did not work, tried for Android 7.0 (which is the present ROM) with Odin v3.13.1, same as above.

Also file-upload is a popup nightmare, please use something else next time.

Other options?

blue lines on twrp

I have the same problem with a Samsung Tab A sm-t580, I have tried different versions of Odin/Twrp to no avail. Its rooted I had to install a different version of busybox to get Titanium backup root access. The red/blue lines still persist after installing twrp (pass) with Odin and a "cannot do nornal boot invalid kernel length" if I use the Twrp app. However once in blue line state I reinstall CF Auto root and it puts back the standard recovery and I can boot up again.

Hey [MENTION=4899305]ashyx[/MENTION], as I tried to explain in my post (#517) your twrp fix from post #407 didn't fix the issue for me.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
You still get the lines in TWRP?

Which firmware build are you running?

---------- Post added at 06:18 AM ---------- Previous post was at 06:17 AM ----------

TWRP doesn't work for P580 at the moment. Root however is still possible via Magisk.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] MajorBoobage:
Indeed, as I explained in my post:

T580, Android 7.0, kernel version 3.18.14-13839138

Build Number: NRD90M.T580XXU3BRF1

Not using an SD card.

Tried your TWRP from post #407, as well as other versions suggested by a couple users, no success.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
You seem to be the only one with this issue.

Are you sure your bootloader is up to date for Nougat?

Why not just update to Oreo?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] MajorBoobage:
I made no changes to the device, I tried to flash your Nougat version of TWRP straight out of the box as soon as I turned it on for the first time.

Should I update to 8.1 OTA through the stock ROM, and then try the process again?

Or should I flash what is found in your post #454 using Odin?

If so which Odin version?

One of the main obstacles for me is trying to collect bits and pieces from this 550+ post thread is a bummer, I wish there was a way to consolidate this into a guide, like the first post is supposed to be, just up to date.

Much appreciated.

I flashed (Odin) your twrp_3.2.3-2_sm-t580_oo_141118.tar onto my sm-t580 and It worked, I now can go back to vanilla LineageOS builds. Thanks a lot, Merry Christmas.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
That's for Oreo, so it's up to you if you want to update.

Not sure if it will work on Nougat.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] hanspampel:
Did you check if the ext. sd card doesn't spit out the message 0MB? Did you check if MTP works, so you have connection to PC in TWRP? This is the current state of affairs. Of course TWRP works, but without access to the ext. SD card and USB connection it is useless for me. You are on oreo?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
I agree with the sdcard issue, though I'm not sure why as nothing has changed config wise, but I'm looking into that.

However according to the recovery log MTP is working OK.

Whether this connected to the sd card not mounting I dont know, but I would at least expect the internal storage to mount once its formatted.

Would anyone be able to post the output of:

ls -laR /dev/block > /sdcard/block.txt

While booted to twrp.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Wild_Duck:
Does SD card work with TWRP

After successfully installing TWRP and booting into it I did a wipe of everything except the microSD card and installed the files from there. There where no problems.

Hope its the right one.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] MajorBoobage:
I had a similar issue, I tried to use an 8gb SD card instead of 128GB, and I formatted it to FAT32 instead of ExFAT, that helped and TWRP was able to mount the SD card. Try maybe that helps.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] hanspampel:
I dont want to format my ext. sd card cause it works with the omni twrp out of the box. And still no mtp in twrp. Btw. did you tried to reboot to twrp again? If so, do you have to format sd card again or does it now works every time you boot into twrp?

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] MajorBoobage:
You only have 1 card? :D go buy a 4gb card for $2 so you can install the things you need instead of waiting days for a fix which may or may not work...
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
I have no connection whatsoever to TeamWin. They are responsible for maintaining and updating the mainline source code for recovery.

You may not realise, but most builds of TWRP are compiled by other devs like me and not actually by TeamWin themselves which can then be submitted for official support.

I have many, many builds of TWRP for many devices, which I haven't submitted for official support.

I could, but I do not like the convoluted submission system. Basically to'ing and fro'ing of emails after contacting one of the team on IRC.

I have asked several times for a proper submissions page to be created which I would be happy to use, to no avail.

All I can say is if you're in any doubt of using anything compiled by myself then just stick with official builds.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] hanspampel:
Nope, still the same.

I have a 64GB sd card. There are my twrp backups, my ROMs and other stuff i dont want to have on internal storage. And im having a working twrp recovery with omni kernel. But it would nice if the official twrp with oreo kernel would work.;)

Hi,

I've paused the Oreo update and still on 7.0.

Which way is easier to do?

a) update to Oreo and then try to install TWRP

b) Install TWRP on 7, and then wait for a Oreo zip to update

Thanks

Wow. Thank you all for the time and work put into this project. It's quite a bit of info to take in and I'm pretty tech savvy (not a pro) by any means.

I read through this whole thread but didn't notice a step by step for a noobie rooter on how to root a T580 running Oreo 8.1

If I missed it could someone please supply a link or if anyone has the time would be able to write up a step by step on how to root a T580. Because my brain is fried from everything I read here.

Charging while T580 is OFF boots into twrp

Got T580 with Oreo 8.1 and twrp_3.2.3-2_sm-t580_oo_141118 + formatted /data + FAT32 SD card.

No issues (e.g. red-blue lines, fs mounts, SD card). Everything on rooted Oreo and twrp backup/restore works.

Appreciate, trust and use ashyx's twrp-s for t350 and now t580.

However got into a new [for this thread, reported on other devices] issue after used up all battery juice.

Attaching a charger while T580 is OFF wakes it (boots) into twrp.

Suggestions/thoughts anyone?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
Probably because you powered off from TWRP.

POWER off from the OS and you should be fine.

Hi,

I used Odin 3.12.3 and TWRP 3.0.2-0 on Android 7, T580

I turned off auto-reboot in Odin and flashed. Odin shows green passed and log say all thread completed success.

However, the device remains on and showed "Downloading". I long-pressed power button, or combination of home/volume-up/power or home/volume-down/power for a min. Nothing works. The device remains up.

What should I do?

Power and volume down for a very long time longer than I have ever remember doing that in the past but eventually it did boot into TWRP ( 30 seconds)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] redhonker:
Did that it went into normal boot, not recovery. What should I do here to get into recovery?

Thanks
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
To get into recovery you need to hold POWER + VOL UP + HOME from power off.

However you'll probably boot into stock recovery.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] redhonker:
So after Odin flash with Auto Reboot disabled, what should happen?

Should I do the following to get into TWRP?

1. Hold power + volume down to get out of download

2. Once the screen turns black, immediately hold power + volume up + home

Thanks
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
You can hold POWER + VOL DOWN + HOME then just switch to VOL DOWN when the screen goes blank.

I was able to successfully flash the TWRP recovery to my SM-T580 tablet and then I was able to flash a custom ROM to it. So now it's rooted with the Oreo android operating system. Thank you for having the correct TWRP recovery for my tablet.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] redhonker:
Which version of Odin and TWRP did you use?

Thanks
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] rcolitz:
I believe that the version of Odin was 2.13 but I was using a friends laptop with windows 10 on it, and I took a screenshot of the actual file that i flashed using Odin. I followed the instructions to the letter by using the AP and making sure auto reboot was not checked but it wouldn't work so I started checking the auto reboot because the tablet would just sit there in the download mode and not respond although odin said it flashed successfully I didn't think it did. The only thing that went wrong was that the data partition on the tablet got corrupted somehow and it couldn't be mounted. I fixed that through the TWRP recovery. I flashed the resurrection remix to it along with Gapps Nano and the adoptable storage patch and SuperSU SR5 so now it seems to be running great.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
The reason it stuck in download mode after flashing is because you unchecked auto-reboot.

This needs to be done to prevent the device automatically rebooting after the flash.

It wasn't stuck in download mode. After flashing you need to manually force a reboot directly to recovery.

Data didn't get corrupted neither. All recent Samsung devices have an encrypted data partition which twrp cannot access. Formatting as you did removed the encryption.

Looking at your screen shot I see you are using a USB device. Did you also use this in twrp? Did you have any issues using a micro sd card?

As I can see you are a tw God so....

Maybe you could help me to get twrp working on the p580 Oreo. I tried some methods but I always got some problems like no external and internal SD or I have to format data every time I boot into twrp.

I was using your build for the t580 and switched files from the p580 kernel.

Maybe you can give me instructions what I can do :D

Thanks.

First, thank you, thank you ! ! ! for all your hard work and putting up with 'us' block heads . . . that step : after we're 'forcing a manual reboot' - yikes ! The needed finger dexterity and mental dexterity to CATCH the reboot back into twrp recovery and not let it do what it really wanted to do... Is a pain. I knew it was possible. . I saw that kid on youtube doing it. . I failed many, many times ( tab went to os boot ) before miraculously steering it into twrp. . Hello sammy s/w engineers laughing their keesters off...
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
Your internal storage issues are because of encryption. You will need to patch the fstab as well as formatting data.

The sd card mount issue is a funny one as this has only appeared with Oreo builds and not everyone has the issue.

I've not really had time to look into it as yet.

Hi,

I have T580, 7.0, kernel 3.18.14-12479655, build NRD90M. T580UEU2BQL1. I tried to root it and failed and reverted back to stock boot and recovery. Knox is tripped.

I tried OTA update to T580UEU4CRK5/T580XAR4CRK7/ but it failed at 32% (Android logo tilted with a yellow warning sign above).

It then rebooted and showed a dialog

Failed to update software

Failed to update firmware. visit Samsung service center.

How do I troubleshoot? Should I flash TWRP and then flash zip myself?

Hi,

T580, 7.0, kernel 3.18.14-12479655, build NRD90M. T580UEU2BQL1

I used Odin to flash (AP) twrp_3.2.3-1_sm-t580_29918.tar (link from [MENTION=4899305]ashyx[/MENTION] earlier post). It was successfully and I was able to get into TWRP.

Then I used TWRP to install Magisk-v18.0. The installation appears to be successful. I noticed the installer log showed encryption is enabled.

But when it reboot, it got the verification failure. I had this before with auto-root so I guess if I flash stock boo and recovery, it probably can boot again. But ...

My main reason to root is to backup one game (Madden NFL Overdrive) for my son. This requires root. I tried TWRP mount but it won't allow me to mount data.

Before flashing TWRP, I tried to OTA update to 8.1 but that failed at 34%.

What could I try now?

Thanks
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] :
you must format /data in TWRP and you can mount this!´Use last TWRP for Oreo!
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
The issue is as soon as you root the system is going to fail an integrity check at first boot as Magisk patches some files.

This is tied in to encryption. The only way to bypass it is to remove the encryption by Formatting the data partition.

Unfortunately this means losing data and settings.

Smartswitch mobile is able to back up apps and settings, but not sure if it will backup games.

The other option is helium backup.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] redhonker:
The game is marked as "backup not allowed" in Helium. I tried Samsung Smart Switch and it did not copy the game data either. I guess I just have to tell him to start from scratch again. :(

So if I just wipe (I think it include data and cache) in TWRP, the system should be able to boot normally. Is this correct?

If that works, I can then flash the pre-rooted 8.1, right?

Thanks

Have you enabled Google backup?

If it's an official download from Google play then it should get backed up.

You can check this by logging into your Google acoount and checking backups.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] redhonker:
Yes, it's enabled. I can see the device name in the Google Drive backup folder. It listed 71 apps but I don't know what is inside. How can I check whether it's included?

Nevermind. Wound up reading through this whole posting and found the right button combination and timing. (gave Thanks! on all the posts I used)

Seems there are many extra instructions that need to be done.

I just bought this device and did NOT connect to WIFI before rooting and such (scared that Samsung will somehow force some nefarious update on me)

Anyway, I successfully rooted after wiping data. Now that I am rooted, have an SU, is there a custom ROM that I should use? That will get rid of the force encryption?

Any good post-root suggestions?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] jaykoerner:
It's unlikely that Samsung would patch any exploits for root/recovery in this device, the only time they really do that is on their phones, because the carrier's ask/pay them to, i doubt they care, the only chance any of this will get patched is if they do a nougat update, and even then unlikely
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] rsandoz:
Thanks, just being cautious. I actually tried Amazon's Fire tablet prior to this one and it immediately did an OTA update. I thought I disabled and protected myself from their shenanigans, but apparently not enough. I knew this when I saw an Oprah ad on my lockscreen the next day :(
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] jaykoerner:
Amazon has reasons to Patch exploits, they need to sell you stuff(and if you replace their os, how will they do it?), that's the whole point of fire tabs, Samsung makes their money of the device so they don't care as much, as long as it isn't hurting them they won't patch it.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] gorthon:
So I rooted my T580 according to the instructions, worked pretty well. The progress bar in download mode did not move, but TWRP was installed anyways. I also installed XPosed and that works well, too. Awesome!

My only problem now is how to get the OTA updates. Before rooting, the tablet offered me an OTA update, which I purposely denied (well, postponed, Samsung does not allow denying it). After root the Update did not come up anymore and on a manual check the tablet says that the system had been modified and I should use a PC to update.

With the XPosed module XTouchWiz you can fake "official" status, though. Knox would still not work, but the tablet offered me the OTA update again. I clicked on install and this is what happens:

Tablet reboots into TWRP recovery, which seems to execute the update command. However, the message "could not mount /data and unable to find crypto footer." appears. This is probably due to TWRP not supporting /data encryption, so it can't access the OTA update file.

Has anyone succeeded in applying OTA updates this rooted tablet? Possible solutions I could imagine:

- locate OTA file, move to SD card and install manually in TWRP

- restore stock recovery

- get encryption to work in TWRP :)

BTW: There are comments on a German forum that confirm this method working for T585 as well.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ajcinkcmo:
Won't boot after formatting data and flashing SuperSU.

Formatting data partition removes encryption and allows you to flash supersu, but now device won't boot after formatting data unless you flash a ROM from within twrp. Only problem is that there are no such Roms yet.

If anyone could create a stock or custom ROM that is a flashable zip you'd be the MAN!

Until then I don't think we'll be able to root our device.
