[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Jordanhicks666:
My sm-t580 is doing the exact same thing with the red stripes everytime i try to flash twrp, ive tried every official version of twrp for this tablet and they all end up booting into those crazy red stripes. So something else strange ive downloaded and tried flashing every official firmware build available for this tab and it seems to be that the only one that will take is the most recent one build number,nrd90m. T580ueu2bql1. i thought maybe like trust 9 was thinking i could just flash back to an older firmware and get twrp to work, but everytime i try to flash and older firmware it does some really crazy stuff with just garbled lines all over the screen so i end up flashing back to this latest firmware.. maybe worth noting i just picked this tablet up from best buy last week, so im not an expert but ive been rooting things for a long time and it seems to me maybe samsung recently changed something in this tablet and it now has something different in the kernel? Like i say i dont know but it would seem like that would explain why none of the past firmware versions will flash and why none of the versions of twrp will work either, different kernel i think, so therefore thinking i may just have to wait until someone more advanced than i writes a new twrp that addresses the issue, or until someone finds some solution to this problem, but glad to see im not the only one with the red lines, just thought id give my input on it, my next step if no one can figure it out is to start trying twrp versions for similiar devices ie the lte and s pen versions. Ah well any help would be appreciated

Frustrated sm-t580 owner :)

You've just given me a headache reading all that. :eek: Please Paragraph your sentences.

If you have the boot image from the latest firmware post it up.

Ehh, unfortunately i am not yet able to upload urls. This sucks i really want to figure this out, there must be a way for me to get this file up for you to look at. Sorry

It's OK I'll sort it.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Trust9:
I tested the whole thing on two devices.

Android 6.0 and Android 7.0

Four different firmwares. Always the same problem.

My last test was CF-Autoroot on Android 6 without TWRP

Autoroot can be installed. Android launches. The device is rooted. When the screen switches to standby mode and I wake it up, the stripes appear again and I have to perform a soft reset.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
That doesn't seem right. I can't see how rooting affects the display?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Jordanhicks666:
Cf-autoroot appears to work fine on my tablet running android 7.0. Ran it rooted all night. No problems there.

However no version of twrp seems to want to flash without causing those red lines.. Dunno if that helps any.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] milaremi:
I am getting the same thing on my recently purchased Tab A 10.1 (2016) unit after successfully ODINing the latest TWRP (3.2.3.0). I have to ODIN back to latest samsung stock firmware to get the system back up again.

--------------------

I'm sporting an SM-T580 which is currently on:

Kernel 3.18.14-12479655 dated Friday Dec. 8th 2017

Build number NRD90M.T580UEU2BQL1

Knox ver. 2.8

December 1 2017 security patch.

------------------------

These graphical artifacts when attempting to boot into TWRP are disheartening. I've been at this for 2 days so whatever insights can be provided would be greatly appreciated!
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Jordanhicks666:
-This is the same problem I am having with my recently purchased tablet as well.

same exact kernel, same date, same build number, same security patch.

CF-Autoroot works successfully, although I noticed there is another guy on the thread for CF-Autoroot who is running into the same problem as us.. when he tries to flash twrp.

One thing I am curious about is if anyone else has tried flashing back to an older firmware, or firmware for another region?

So far I Have Tried to flash all 5 of the American firmwares available for this device and the only one that works is this one, Build number NRD90M.T580UEU2BQL1

All the rest result in more graphical artifacting immediately after booting.

I have a feeling that Samsung may have recently changed something about the kernel and it may take a pro boogie ninja twrp jedi like mr. ashyx to do some programming magic with the recovery kernel for us :)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
Can someone who is running the latest T580 firmware try this out:

https://androidfilehost.com/?fid=1322778262903990042

.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Trust9:
is this the same version as on the homepage or your own custom?

I have already tested the current version from the twrp homepage. I'm afraid it doesn't work.

But if there are differences, I'd be happy to test your version again
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Jordanhicks666:
I tried flashing this with ODIN,

unfortunately got the same result,

Same red lines,same graphical errors.

Flashed back to stock.

man thank you for your efforts
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
I'll take another look.

With which firmware did this start happening?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Jordanhicks666:
Kernel 3.18.14-12479655 dated Friday Dec. 8th 2017

Build number NRD90M.T580UEU2BQL1

Knox ver. 2.8

December 1 2017 security patch.

This is the exact info,

This is what came on the tablet when i bought it 6 days ago,

also strange i cant flash any other firmware version besides this one with out getting more, (but slightly different) graphic artifacting,

(Green blocky lines instead of red ones when i flash older firmware)

Again thanks again.. Anyway i can help im with it.

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Jordanhicks666:
the conclusion that ive came to, not that my opinion matters but,

Samsung must have updated the bootloader in this build, which, as far as I can tell, would perfectly explain why we cant roll back the firmware,

and why all the versions of twrp are incompatible with this build. -amatuers opinion here-. So therefore I have no clue what to do except wait.

modifying twrp is far, far beyond me. but I suspect with Samsung planning an oreo update for this tab, and it still being sold in stores and such,

that more and more people will be having this problem and surely a new twrp or a patch of some sort will show up sooner or later,

best of luck. peace, love, and all that good stuff :)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] milaremi:
I will do the same, hopefully the TWRP folks can find a solution that works with the latest firmware.

Thanks to all!
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] klaberte:
Jordan and Mila,

I haven't followed all of your posts, but you certainly have other options than to just wait, i.e. not use your tablet. Unless you need Oreo, these instruction should still give you a working, rooted Tab A running Android 7.0:

https://xdaforums.com/galaxy-tab-a/how-to/newbie-friendly-twrp-root-tab-tablets-t3552509

No need to only consider USA builds. Most regions' firmwares work just fine.

Apologies if I've missed the point.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
Something is not making sense here. You guys say you're having issues with twrp yet over in the treble thread no one seems to be having issues?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] 234herobrine432:
Having this problem too, no idea how to downgrade the bootloader. It's possible to use the recovery commands on the pc but no way to format /data so every rom I install says theres a problem with encryption and I have to factory reset.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:

If it doesn't boot, can you post the stock recovery image?

This one let's the tablet just reboot every 5 seconds

Sure, I have the stock.img, would be awesome If you can figure out what's wrong.

recovery is from the latest stock rom.

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
I will go back to basics and rebuild everything from my own sources.

First thing I need to do is compile a bootable kernel.

Just to confirm your device is the T580?

EDIT: Compiled this one with the new DTB from the recovery image you supplied.

Haven't really used this account (I mostly lurk on here unless I have a question because I'm not a developer) but I just wanted to say thank you for working on this, ashyx. I bought the SM-T580 the other day but lost the receipt as I was running to catch the city bus. Now I'm stuck with it and hoping for a solution. Please, keep up the good work and if there's anything I can do to help (even though I don't know much) then just say. :)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Jordanhicks666:
My dumbass flashed to an even newer firmware

July 11- 2018

T580XXU3BRF1

Its the spain firmware and now i cant even flash back to the american January 1- 2018 BQL1 firmware, lol, stupid,

So im hoping whatever new twrp you compile still works for me now too, thanks ashyx for your efforts
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] 234herobrine432:
I've send him the newest recovery.img, if it'll work for me, it will work for you either :)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] haibane:
Able to get out of the red vertical lines? Nevermind I fixed this with the stock firmware.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] thedemonschild:
Does that mean that TWRP is fixed on this device? Or are we still waiting for a solution?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] haibane:
You did read what I said right?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] thedemonschild:
I'm sorry, I just don't really understand. I'm an almost complete noob so could you tell me if it's working and if it is how I can get it to work on mine? Sorry.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] haibane:
Not working... I just said I flashed the stock firmware to recover from the red bars. Not sure how you gathered twrp was working as the stock firmware includes a recovery. That's why I asked if you read what I said.

I do realize English isn't most people's first language. Sorry if I came across as rude.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
No its not as yet. I'm having issues with Samsungs kernel source as usual. Many compiler errors.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] 234herobrine432:
For now: Users who get red lines can't use twrp. Just use the stock rom.

ashyx maybe gets it to work soon, but I don't know when this is. We have to wait and pray :D

edit: sorry didn't see the next page
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] thedemonschild:
I live in Rhode Island and the only language I know is English. Sorry dude, the way you worded it just didn't make sense to me. No need to get snippy.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Jordanhicks666:
Easy, easy now, but for anyone who may not know, the CF-autoroot method does work for those of us who get the red lines.so there's that for now.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] haibane:
I didn't know that. thanks for the information.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Jordanhicks666:
Just works to get super user & root. flashing twrp in anyway after that still results in red lines
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] haibane:
Even using the twrp app?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Jordanhicks666:
Even using the twrp app produces the exact same results, already tried it lol, different twrp versions, different firmwares, can't flash back to marshmallow anyway, there appears to be no way as of yet to get a custom recovery if you have the bql1 firmware or newer.

Gotta wait for someone who really knows what there doing with compiling twrp. like Mr ashyx

However if you do find a way be sure to let us know haha, good luck
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] haibane:
I'll have to try a few things. Not dead set on wanting to build my own twrp just yet...
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] milaremi:
Just a quick note to all of you helpers on this thread. Thank you for your efforts! I will continue to monitor and hope for a TWRP update or elegant solution to the "Red Bars" issue. If I come across anything that might help, I'll post it here. Thank you all again, you're great!

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] 234herobrine432:
Still not working, same red lines.

but this recovery is booting and working, even touch.

Thanks for your efforts :) can it be that twrp is using an older gpu driver that's blacklisted on that new kernel?

You can also use the recovery, you just have to put magisk.zip onto your phone and connect it while in recovery to the pc, then use a command prompt with adb:

adb shell twrp install /pathtozip/magisk.zip

did that to mine, works fine :)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
In that case can you use adb to pull the recovery log and post the file here?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] 234herobrine432:
Sure
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] tdvolland:
So THIS will not work?

I am an almost noob who now owns the T580 and wants to root it, to use SU to get rid off some of the stuff it came with.

As the thread is a bit confusing for a noob, so my question:

This:

and there, the top line, for the BRF1, will NOT work?

If you have android 6 you're fine, flash twrp as usual and then root with magisk

On Android you can only use Cf-Autoroot or as I described above, with twrp and the pc

good luck!
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Alkarl:
I only get a black screen (the red lines are gone) when using this recovery but I can still use adb to reboot

(I can't post links yet)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] tdvolland:
I don't understand your question... I wrote that I own the T580 / BRF1 and the last 20 posts were about fact that on the BRF1 version, the attempt to root will lead to the red lines...

So https://desktop.firmware.mobi/device:752 leads me to: https://desktop.firmware.mobi/device:752/firmware:16671

and the obvious quetion is: Will this work on my tablet or only to the red lines?

Thanks

---------- Post added at 10:17 AM ---------- Previous post was at 10:14 AM ----------

Thanks,

The BRF1 always has Android 7.0 So, an attempt to root the tablet will only result in the red lines?

https://android.gadgethacks.com/how-to/android-basics-root-with-cf-auto-root-0167401/ will not apply when Android 7.0 is installed?

I am sorry, but several of the posts in this threat are quite contradictory about that....
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] 234herobrine432:
Root doesn't end in red lines, red lines only while in Twrp. Stock rom will work fine

You can even install a rom with sideload or adb shell twrp install "rompathandname" but sadly I had issues with encryption so I have to reformat my data partition, not possible with those red lines
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
You should still be able to format data using adb.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] 234herobrine432:
You can only wipe data, but I need to format, any idea to do this?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
Try:

umount /data

mkfs.ext4 /data
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Jordanhicks666:
Look heres a simple answer for you, on the brf1 or any firmware at all for this tablet ,cf-autoroot DOES work, all you gotta do is make sure u have oem unlocked and boot into your stock recovery and do a factory reset, u MUST do this factory reset or u get some encryption error, at least on mine, then, after the factory reset boot directly into download mode and flash the cf-autoroot package and let it reboot and do its thing, then itll reboot and hang( at least it does on mine) so so hold down the download buttons until it resets, hit cancel to restart and voila setup ur tab and youll have root with super user installed on stock firmware. Thats it if all you want is root.

The problem is coming when you try and flash twrp but it sure seems like ashyx is getting close to figuring that out so if u want twrp probly jusst gotta wait a lil while longer, hopefully this cleara up any confusion

And to add to that twrp does work on some 7.0 firmwares, the only ones its not working on is firmware from January 1st 2018 (bql1) or newer
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] haibane:

Thank you... well, BRF1 is certainly newer. But I simply want it rooted and have SU.

On the other hand, if you read your description yourself and then imagine how a noob could possible use that description...?

Your explanation is only usable by a person who already knows all that.... right? I don't even know what a stock recovery is....

My last tablet was an ASUS Mediapad 7 and a few years ago, I simply installed kingroot, pressed a button... and voila.... rooted and SU.

Thank you...
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
According to the log you are running firmware version T580XXU2BRB2 which means you could downgrade your bootloader to an earlier version which may make twrp work. For instance BQJ1 or even earlier as long as it's a revision 2 firmware I.E. T580XXU2....

Just flash the BL part with ODIN and see if TWRP works.

I have also requested that Samsung release the latest kernel source for BRF1 as I believe Samsung have changed something in the graphics source code as there are references in the log to FBDEV graphics sources.

OK, I flashed an earlier bootloader (T580XXU2BQI9) and now the bootloader is doing the line thing, like the Samsung logo and the battery charging logo is stretched vertically.

I managed to reflash the current bootloader (T580XXU2BRB2) and it went back to normal. Download mode was just a blank screen.

Did I use the wrong firmware or is something else going on?
