I failed similar times to root my phone with twrp 3.2.xx and 3.1.xx. I used Odin 3 v3.13.1.
Any ideas or thread links for the young padawan?
I appreciate your advice masters :good:
Using Odin Flash TWRP latest from the note 8 TWRP thread here on XDA, one on their site is not latest.
Install magisk manager app from play store.
Download magisk from the app.
Reboot to TWRP and flash the magisk file just downloaded.
Reboot and check magisk manager for root and hide.
Should be good.
Nope. Not working and still ends in a bootloop and it's unable to mount the internal storage.
Something went wrong, so.. my phone is unable to boot the system after that!
The issue is the version of TWRP and Oreo, its not yet compatible on this device, it needs porting over
If you want MAGISK you need to do it all in one hit.
Flash TWRP
Select Read Only Option.
Format Data
Reboot Recovery
Flash the DM Verify Encrypt file
Reboot Recovery, You could be able to flash files wihtout a Data mount error.
Now flash the files you want, i..e MAGISK
Once you have booted the ROM and return back to TWRP you are unable to mount Data.
This can cause various issue when flashing files
Funny you.. How can I format if the internal storage isn't able to mount?
"Select Read Only Option.
Format Data" <-- seems like a contradiction to format a missing
partition.
I think we need to wait until someone will port the twrp for Oreo. cheerio!
Because it needs to be done when you first flash it.
Once you have flash Oreo, Then TWRP, You boot into TWRP and format. You then Flash the DM Verify.
Data is accessible, its empty but accessible, Flashing any files like MAGISK work without any errors.
I have it all working on mine without any issues, I do know if i need to flash any additional files it wont work properly due to Data no longer mountable.
There is a updated version of TWRP that fixes this, but its not been ported over.
I have a rooted SM-t817t and have been attempting to flash Lineage 14.1 to it through TWRP 3.1.0-1_ashyx.
I have tried to flash with the gts210ltexx and the gts210wifi and the results are the same, receive the Error 7 message.
After reading up on other threads I attempted to alter the script to either tell it that the ROM is for the gts210ltexx or just remove it entirely and still getting the error.
Also attempted to run it without authentication.
I have read that the t817x tablets can be flashed with the t810 ROMs but have had zero success with doing so at this time.
I am unsure how to proceed from this point.

Format (not wipe) DATA and if that doesn't work FORMAT the system partition.
If neither works then maybe you should use an updated twrp.

Thank you for the advice, I will update to the latest TWRP and then format the data and try that. Will report back with results.
After formatting the data and updating to the latest TWRP, 3.2.3-1, I come across the same error 7.
Have updated the script filed to make certain no trace of verification exists for the ROM and still receive the error.
Have now attempted at least five different ROMS all with the same results.
The following is a summarized look at the details it gives.
Installing zip file 'lineage.zip'
Checking for Digest file...
Skipping Digest check: no Digest file found
Warning: No file_contexts
detected filesystem ext4 for /dev/block/platform/15540000.dwmmc0/by-name/SYSTEM
Patching system image unconditionally...
E1001: Failed to update system image.
Updater process ended with ERROR: 7
Error installing zip file '/lineage.zip'
Updating partition details...
Failed to mount '/hidden' (Invalid argument)
...done
Update: I have now wiped data but have not yet formatted it. I believe I will need to install Magisk for that.
However based on other recommendations I have come to find out about the encryption on the Samsung storage and that it might be causing the issue.
I have tried to circumvent this by formatting the data into ext2 then back to ext4 and restarting recovery, but so far this has not worked. The error 7 message persists regardless.
Will come back with further updates.

You didnt read my previous post correctly.
You don't need Magisk to FORMAT DATA.
The FORMAT DATA button is right there under the wipe options.
However what you did would have formatted DATA anyway.
Now do the same for the system partition after formatting DATA.
Do not reboot just check DATA and SYSTEM can be mounted then try and install the zip again.

Formatted the data and the system. Verified they were both mounted. Then attempted to flash the ROM.
Error 7 message still appearing. As does the unable to mount hidden.

Unknown. I have tried reflashing the stock firmware and that still failed in Odin.
I have given up at this point and restored from a backup. Thanks for the help however.

Can you share root procedure for the sm-t817t my roommate has one for sale, I'll only buy it if I can root it though.
If you had problems (like myself) with installing custom roms via twrp where the system would stuck in a bootloop and the recovery would return "No OS Installed" error, here's the solution to how to fix it:
1. Enter TWRP
2. Go to Wipe - Format Data
3. Restart recovery
4. Copy the rom to internal storage and install custom rom
Enjoy!

Whoops, forgot it doesn't have the sd card slot I've edited the first post.
Apparently, when you change rom type (for example, from official stable to xiaomi.eu weekly), you have to do this complete device wipe. For updating to a new version only wiping dalvik and cache should do.
not work on me
Thanks but didn't work for me either. After following your instructions, the phone booted into TWRP again. It no longer says there's no OS, but it won't boot. Just stalls into boot animation for a while and then goes into twrp recovery... Bummer!
Update: March 24 2022: This ROM has been retired and a new one based on LOS 19.1 (and TWRP based on Android 11) have taken its place. New thread here: https://forum.xda-developers.com/t/...4-2020-lineageos-19-1-and-twrp-3-6-1.4421365/

Update 9:46am EST July 15 2021: new builds of TWRP and LineageOS with TWRP touch fixed and LOS w/ space for Gapps is now live.
WARNING: USE AT YOUR OWN RISK.
I have successfully ported TWRP and Lineage OS 18.1 to the Samsung Galaxy Tab A7 10.4 (2020), aka SM-T500. This is my first time porting TWRP or LOS, so there may be issues unknown about at this time. Thus far, the only known issue is that the touchscreen in TWRP does not work. This can be worked around by using a USB mouse and/or accessing the device via ADB.
Here are the steps to follow:
Update your device to the latest stock ROM (as of this writing) either using the built-in system updater or via Odin. You want the build that ends with "3BUF3".
Unlock device bootloader using instructions from other threads. This will wipe your device.
Boot into download mode and flash "vbmeta_disabled_R.tar" via Odin in the "Userdata" slot to disable verified boot. This will wipe your device again.
Boot device back into download mode and flash TWRP via Odin in the "AP" slot. If you boot up into the stock ROM rather than booting directly back into download mode then go through the initial setup process of the stock ROM and enable developer tools and ensure OEM Unlocking is still enabled (VaultKeeper can possibly undo OEM Unlocking if you get to the ROM but don't go into Developer Tools and view OEM Unlocking is enabled, so make sure to do this).
Boot device into TWRP (recovery mode) and format (not wipe) your data partition. Then reboot back into TWRP.
Push LineageOS (super.new.ext4.img) to device. Ideally push it to an SD card formatted with ExFat or EXT2/3/4 (FAT/FAT16/FAT32/VFAT won't work due to file-size limitations).
Install LineageOS image to "Super" partition. Make sure to select "Install from Image" in order to show .img files in the install selector screen.
(Optional) Push NikGapps Omni to your device and install the zip. Make sure you include a "nikgapps.config" file in your "/tmp" folder that is configured to install to "system" rather than "product" or "default".
Reboot to system. You should now be in LOS with Gapps.
(Optional, but recommended): Install Magisk via TWRP
(Optional, but recommended): Run fix script to fix brightness slider not working and to make Magisk work. If you didn't install Magisk but only want the brightness fix, just enter "n" when prompted in the script. To run the script:
NOTE: Script has .txt file extension to allow hosting on AFH. Remove that so it's just .sh to match the instructions below.
Download and push to device when booted into TWRP
adb push sm-t500_fixes.sh /tmp
Enter an adb shell
adb shell
Change directories and set permissions
cd /tmp
chmod +x /tmp/sm-t500_fixes.sh
Run script
/tmp/sm-t500_fixes.sh
Tips:
If you are not seeing all of your storage space in the OS on the internal flash, boot to TWRP and format data.
Flash TWRP via "AP" slot and flash VBMeta_Disabler via "Userdata" slot in Odin.
Flash LineageOS as an Image, not as a Zip.
For Gapps, use the latest NikGapps for ARM64 and Android 11/R.
For Gapps, make sure you install to the System partition and not Product. To do this you need to slightly modify a nikgapps.config file. Instructions on that can be found on the NikGapps site.

Here are the rough steps to follow:
Unlock device bootloader using instructions from other threads.
Patch stock ROM (AP) using Magisk, then flash rooted ROM. Will likely need to wipe device after this.
Boot into rooted ROM and ensure "OEM Unlocking" is still enabled in "Developer Tools".
Boot back into download mode and flash "vbmeta_disabled_R.tar" to disable verified boot.
Boot device back into rooted stock ROM to ensure things are still functional (may require a device wipe at this step).
Boot device into download mode and use ODIN to flash TWRP recovery.tar file via "AP" slot.
Boot device into TWRP to verify functionality (hold Vol-Up + Power during boot).
Access TWRP via adb using "adb shell" or with USB mouse (touch functionality currently not working).
Format data partition on device.
Via ADB shell: twrp format data
Via USB mouse: Wipe -> Advanced -> Format Data
Boot device into download mode.
Via ADB shell: twrp reboot download
Via USB mouse: Reboot -> Download
Flash LineageOS tar file via ODIN using the "AP" slot.
If device boots into TWRP after flashing LineageOS, use USB mouse to select: Reboot -> System
Device should boot and stall for ~1m at the Samsung logo screen with red text below, then should go blank and then display LineageOS boot image.

Which slot to flash the vbmeta?

Thanks,
After flashing the vbmeta it booted into recovery automatically after what looked like a bootloop in progress, so I wiped with factory reset and then it rebooted fine. (still not sure exactly what the vbmeta does I was hoping it would make it so i didnt get that stupid pop up asking me to hit power button to continue booting due to it having the patched os) anyhow booted fine and twrp installed as you stated without touch screen but mouse with otg works fine. (great job so far) On to LOS... I think I should have checked oem lock before flashing LOS as when I installed I get stuck at boot screen that says oem lock is on... must have been from my factory reset... (facepalm)
Nope... Still sticking on boot with the following showing on the screen...
RPMB fuse not set
RPMB Provisioned
Current BInary: Custom (0x30f)
FRP Lock : OFF
OEM Lock : ON (U) {this was off verified before flash}
KG Status : Checking
Waranty Void : 0x1 (0xE02)
Quallcomm Secureboot : Enable
RP SWREV : B3 (1,1,1,3,1,1) k3 s3
secure download : enable
grdm status : normal (d0000501)
did : 041ce2d22dba
this is displayed in the corner on the bootscreen and looks like it belongs on the download screen, anyhow booting into twrp from this point works however factory reset fails with unable to mount key(something and key(something else) i figure i will let it sit a while as I know sometimes it just takes first boot a while to go through however it doesnt seem to be the problem. Have you had a positive install of the LOS? I am wondering if I had maybe gotten a bad copy of the file. When i go to install I get a pass in odin so not quite sure where to go from here other than back to the factory image any help to get this going would be great... I took on this task cause i needed someting to take my mind off the severely crappy week I have had... so looking forward to anything you can share here...
Actually, userdata is the slot I always use. It might work in both though.
Something to mention: there is not enough space on the /system partition to flash Gapps. I created a build that supports it (with a resized /system partition) but I couldn't get it to flash via Odin. The only way I got it to work was by flashing it via TWRP as an img file. I will be posting that soon. Unfortunately that will be the end of development for now as I hard-bricked the device and need to wait for a repair or replacement. Should be back developing in 2 weeks.
Nevermind what I said here.

You may need to get an otg cable for a USB mouse and choose "reboot system" from the gui. Alternatively, look at the /dev/block/by-name/misc partition and try blanking that out with dd. That has worked sometimes.

Also, from an adb shell, try "twrp reboot". Supposedly that should boot to system, but I feel like in testing I got mixed results. According to the TWRP documentation though that should be the answer.

Can a mod move this to the rom release section?

I've not been able to flash this yet but I know that the latest TWRP versions have a way to fix the system partition to accept gapps. /Wipe/Advanced check system then resize. Sometimes you have to do it more than once if it is a large gapps.

I will look into that, but I'm not optimistic it will work. This device does not separately present the system partition, rather it uses a super partition which contains system, vendor, product, and odm. TWRP only shows me the super partition for working with. I was able to resize the system partition by expanding the Lineage image and file system on my pc to match the original stock system partition, then rebuilt the super image with the other partitions it needs.
Hello, I have a Samsung Galaxy A6+ with latest fw installed.
(italian version)
A605FNXXU7CUD4
The phone is totally useless after the update to android 10, it takes AGES to perform any action, even open the Camera or open a Message.
Already tried to wipe everything, hard reset, reinstall fw. Still useless.
Since I’d like to downgrade to Android 9 to have back a useful phone, I tried to install the latest Android 9 fw with Odin.
A605FNXXS5BTB1
But it fails, saying SW REV CHECK FAIL : [aboot] Fused 7 > Binary 5
What can I do?
Is there any chance to downgrade this phone?
Thank you
1. Unlock your bootloader.
2. Flash custom recovery for your device.
3. Go to custom recovery (TWRP) and flash any downloaded custom rom (for your device), GSI or save stock firmware as flashable zip with tool like ClassyKitchen.
4. Flash Magisk or RMM-bypass-v3 in TWRP to protect your bootloader from getting locked again.
Backup your personal data at first, of course.

Almost done, but I can't find any custom rom available for download. Can someone help? Since wwith twrp I cannot install a stock rom. Thanks in advance.
I managed to flash a so called Ari's rom, but I think the phone is now bricked. It is on bootloop on the first screen of Samsung (with phone name and so on) and with SET WARRANTY BIT : KERNEL at top left. I think it is time to trash it or does someone have any hint? Thanks

I proposed three different options: custom rom, GSI (generic system image) or conversion stock firmware to flashable form. If there's no good custom rom for A6+, then don't worry - you can still try another options. Try playing with Generic System Images:
1. Flash your current stock firmware as usual in Odin.
2. Unlock bootloader and flash TWRP.
3. Go to TWRP.
4. Wipe partitions cache, dalvik, data, system (don't wipe vendor partition - it's needed).
5. Flash GSI image (recommended will be at first phhusson's AOSP (Android 9 or 10)) as "system image". You always need to choose and download "arm32_binder64" variant of img file.
6. Reboot to your new system.
Second option is to convert stock Android 9 firmware into flashable form.
1. Download ClassyKitchen tool.
2. Import downloaded Android 9 stock firmware (for your phone) into it and save it as flashable zip.
3. Go to TWRP.
4. Wipe cache, dalvik, data, system and vendor.
5. Flash your previously done zip with Android 9 as any other flashable zip in TWRP.
6. Flash Magisk or RMM-state-bypass-v3 in TWRP to prevent your bootloader from getting locked again.
7. Reboot.
I went for the second option, in Classykitchen I loaded the stock android 9 rom and selected
BUILD ZIP ROM (for recovery).
Then installed with TWRP following your wipe indications.
Success.
But when I went to install RMM-state-bypass-v3 I got the error impossile to mount /system.
So I rebooted twrp and before anything I manually mounted SYSTEM in twrp in the dedicated MOUNT menu, and I did everything again from wipe to install.
Is this procedure correct?
Success, success also for RMM-state-bypass-v3.
I rebooted but I'm again stuck in the same loop described in my previous reply.
When I selecr REBOOT in twrp, do I have to flag anything? For example System?
Regarding the first option, if I go there:

Yes, it's correct. If RMM bypass or Magisk.zip was flashed without any errors in TWRP then everything is okay. Just reboot to system in TWRP after that - there is option to reboot directly to system. First boot always can take a bit longer than next boots.

You always need to get any "arm32_binder64" (always AB) image. Gapps or vanilla is just your choice. Just get Android 9 or 10 image and flash it as "system image" (but wipe at first partitions specified in my previous post - don't wipe only Vendor partition, because it contains important things). Android 12 GSI still aren't stable. Android 11 - maybe will work properly. Android 9 and 10 should work fine. There is even short article about GSI on Galaxy A6+ with some fixes for that device attached:

But something weird happens: I install the ROM with success. If then I try to install Magisk (or Rmm) it fails with error 7.
And twrp says No Os installed if I reboot.
But if I try to install Magisk after rebooting into twrp after installing the ROM it goes without errors.
But anyway I have the issues of No Os installed.

You need to reboot to recovery after flashing new system, because just after flashing TWRP doesn't recognize it - that is why you see that "no OS installed". Just reboot your phone to recovery again (you have such option in TWRP). In case of GSI (except maybe CAOS, LineageOS Q/R mod) Magisk or RMM bypass is not needed.
Btw, in case of any problems with hardware support on GSI flash also that patch in TWRP (it may be needed to mount "Vendor" partition in TWRP before flashing that fixes):

Thank you again for your help.
I already rebooted to recovery and twrp keeps saying NO OS.
I'm using twrp 3.5.2_10-0.
I'm starting to suspect that this behaviour is due to the fact that this version of twrp could be too much new and unstable for my phone.
So I'd like to install an older version of twrp with Odin, as explained here:
TWRP for SM-A605FN Samsung Galaxy A6+
How to Install TWRP 3.2.3-1 on Galaxy A6+ SM-A605FN Android 8.0.0 Oreo. Once you installed TWRP recovery on your Samsung Galaxy A6+ SM-A605FN, you can customize it, Rooting or installing custom ROM
www.recovery-mode.com
But I cannot manage to go into download mode again, even from REBOOT menu of twrp it doesn't work, I keep staying in the loop explained before.
Moreover your first option of GSI need me to go into download mode to install the latest stock ROM with Odin.
I just manage to get into the attached screen.
Any idea?
Thank you again
It's not possible to ignore that message and just flash latest stock firmware via Odin? Odin refuses flashing latest stock firmware?
Other builds of TWRP for your devices you'll find here:
Releases · roynatech2544/TWRP_device_samsung_a6plte
Contribute to roynatech2544/TWRP_device_samsung_a6plte development by creating an account on GitHub.

But don't use TWRP older than 3.4.0, because it doesn't have support for "Vendor" partition.
Yes, I managed to ignore that screen and go in download mode again.
I tried to follow your first option since the second one was not successful.
Installed latest stock and then twrp 3.5.0-1.
Wipe as you explained, I flash the Gsi
system-quack-arm32_binder64-ab-gapps.img
The flash is very fast, but no errors, is it normal?
After that I reboot to recovery in order to flash
Disable_DM-Verity_ForceEncrypt_11.02.2020
it goes but just at the end it gives the error
failed to mount /odm no such file or directory.
And if I reboot to system the phone loops as always.
I'm losing all hope...

It's okay, but it's possible that you'll always need "vndklite" images for working camera.

If you flashed it as "System Image" and it was successful then yes - should be fine. DM-Verity isn't needed for GSI - only RMM bypass v3 is sometimes needed (on CAOS, Lineage Q/R mod and maybe in case of some other images). On usual A600FN RMM bypass is not needed on phhusson AOSP. Just format "Data" partition (format, not only wipe) - it will remove encryption for you.
Procedure of flashing should be like that:
1. Wipe: cache, dalvik, data, system ("Vendor" partition leave untouched, because it's important for GSI - that is why you needed to flash stock firmware at first, because it adds vendor files for your phone, but it's needed only once, just don't wipe "Vendor").
2. Flash your GSI as "System Image".
3. Reboot phone (to recovery again).
4. Mount your "data", "vendor" and "system" partition.
5. Flash your zips: RMM bypass v3 (optionally Magisk).
5. Reboot to your new system now.
In case of any hardware support problems, reboot to TWRP again, mount "Vendor" partition and flash that fixes:

Try to boot Android 10 or Android 9 images. If it will succeed, then you can try flashing Android 11 images and check what works, and what not. According to that article

I don't know what are those images. Can you explain better?
When I proceed with RMM bypass V3 I see the errors in the attached image. It seems like there is a problem in writing to /system.
Can this be related to the hardware support problems you mentioned?
I tried with different versions of Twrp already and with Havoc Os too.
Should I try with flashing a different ROM ?
Thanks again

Just look at filename of system images. But as I see, it's apparently important on Android 11 and newer. For now, try to boot Android 10 or 9. Let's try with that image:
https://github.com/phhusson/treble_experimentations/releases/download/v222/system-quack-arm32_binder64-ab-vanilla.img.xz
1. Decompress that image.
2. Copy to SD card or to internal storage.
3. Wipe cache, dalvik, data, system.
4. Format data partition (it's needed only once).
5. Flash downloaded and extracted file as "System Image".
6. Reboot phone to recovery (again).
7. Select in TWRP: Mount -> system, data, vendor.
8. Flash RMM bypass v3 (or Magisk).
9. Reboot now to system.
10. In case of some things not working, go back to TWRP and mount vendor partition (Mount -> tick "Vendor" -> go back to flashing zips) and flash that:

11. Reboot to system again and check if now everything works properly.

Yes, because you need to mount that partitions in TWRP:
Mount -> tick "system", "vendor" and "data" - and now flash whatever you want.
The only "receipt" which isn't giving installation errors is following your last instructions but avoiding to reboot to recovery after ROM flash (used Vanilla), and using Magisk v22 with unticked the line called "skip digest check" . See attached images.
Anyway, still no success to get into android.
Also tried fixes.zip.
Maybe I have to try with sideload ?

Everything seems to be okay in your photos. What happens when you press "Reboot System"?

The phone goes into loop with the attached screen and black screen alternatively.
On the top you can see SET WARRANTY BIT: KERNEL, it should be normal right?
Do I have to set something inside MOUNT of twrp before rebooting to system?

I've never had such problem, but according to that thread it seems that it's a fault of modified kernel (so don't flash Magisk with GSI, because it patches kernel).
Try to flash stock firmware, unlock bootloader, flash TWRP, format "data" partition, wipe partitions (cache, dalvik, system, data) and flash GSI image as "system image". And reboot to system.
Don't flash RMM and Magisk for now - and check if system will run properly.
