OP2 cannot upgrade from Oxygen OS 2.2.1/Cannot flash TWRP versions newer than 3.0.2-0

So.... Pokemon Go has a lot to answer for......
I have run into a really strange problem when trying to install an OTA on my *unrooted* Oneplus 2. I have been trying to fix this for days but I have completely run out of ideas.
I originally had a working stock Oxygen 3 (Marshmallow) rom with TWRP recovery on my device (not sure of the version). The device was rooted and apart from not being able to install OTAs, I was fairly happy with the setup. Then along came the Pokemon GO update that banned rooted devices. Ok, "big deal" I thought. I was quite content playing Ingress instead (a far better game by the way that doesn't rely on a "pay to win" structure). I really wasn't too worried but then I found out about "systemless root" and "Magisk". I thought that if I installed this correctly I could still play a bit of Pokemon GO when I wanted to and could toggle a root button in Magisk Manager to install OTAs when they became available.
This is where the problems started.
I followed a guide on how to unroot and install Magisk and "Phh's Superuser". The problem was that the Phh Superuser was being denied permissions for Magisk Manager, there were no pop up notifications prompting me to give it access, just toast notifications. I couldn't for the life of me figure out how to give it permission so the "enable root" slider button kept sliding back, not allowing root. This is when I used SuperSU ver 2.76 (Magisk version) and it seemed to work fine. I now had a stock Marshmallow rom with TWRP and Magisk Manager all working exactly how they should be. I could toggle root and play Pokemon GO, then return to a rooted state when I needed to.
"Awesome, mission accomplished." I thought. Now I just need to toggle root off, download the latest OTA and install it through Flashfire.
First I made a complete nandroid backup (as I've done with other devices many times before) through TWRP. I even copied the backup folder to my PC in case something went wrong.
Well, this is when the nightmare started.
The first mistake I made was to use Flashfire when it clearly stated that Oneplus devices were currently untested. Not sure if it was a big issue or not, but it was a mistake none the less. The second mistake I made was to not stop the stock recovery being replaced when prompted before the reboot. I assumed (and it even states in the app) that the custom recovery should be reverted back to the stock recovery when attempting to apply OTA updates.
So I went ahead and rebooted, waiting for the OTA to install. I'm fairly sure from memory that it went into the stock recovery, flashed the OTA and restarted.
This is when the phone soft bricked.
"Oh well, that is why I made the backup." I thought.
I reflashed TWRP in fastboot mode and attempted to restore my backup. No dice, the phone was still soft bricked.
(And by "soft bricked" and "boot looping" I mean the Oneplus logo was in the middle of the screen, "Powered by Android" was at the bottom and the two blue LEDs for the buttons either side of the fingerprint scanner/home button remained on. This for me was the tell tale sign of the soft brick because these two light go off after a few seconds after rebooting usually.
So from here I have tried EVERYTHING. All I really want now is a working stock (rooted) Marshmallow rom with TWRP. I have downloaded many different full rom zips and attempted to flash them through TWRP with no success, I have returned to stock recovery and tried flashing signed roms with no success, I've even tried flashing the official CM13 rom for Oneplus 2 (with the correct GAPPs and kernel) through TWRP with no luck.
But here is where it gets interesting......
There are a few things that are really weird...
1. I have always been able to get into Fastboot mode and ADB and Fastboot commands "work".
* Operations succeed but don't stick (for example trying to flash TWRP versions 3.0.2-1 and 3.0.2-2 through Fastboot mode result in no recovery being there at all.
2. I can flash TWRP recovery though Fastboot mode but ONLY VERSIONS 3.0.2-0 and lower. I can also successfully flash the stock recovery.
3. I can flash OxygenOS 2.2.1 but NOT ANY VERSION RELEASED AFTER THAT. Doing so results in the soft brick "bootloop" I mentioned earlier.
4. Attempting to flash the official CM13 rom for Oneplus 2 doesn't work either. Originally I got the error 7 message, but after editing "Updater-script" in the rom and re-zipping, the process seemed to work fine in TWRP but the reboot gave me... you guessed it... a softbrick.
I have flashed custom roms on a few different devices before so I'm not a COMPLETE newbie when it comes to this stuff, but I am by no means a developer or even anything close to one. I have bricked this phone in the past (long story, involved getting it without an invite and it being shipped to me with spyware on it) but I used a guide very similar to this and it worked a treat.
www(dot)androidbrick(dot)com/unbrick-oneplus-one-two-3-qualcomm-hs-usb-qdloader-9008
So, thinking that this process would format all partitions and start me from scatch I tried it. It worked fine but I was still unable to upgrade from Oxygen OS 2.2.1 or install TWRP versions 3.0.2-1 or 3.0.2-2.
I have tried all sorts of things. I have wiped, flashed and wiped again. Factory resets, dirty flashes, clean flashes.... everything. All sorts of different sources for the TWRP images and Oxygen roms... nothing seems to work.
It's just so weird considering it's not a hard brick... just a soft brick.
So I really need my phone so I am sitting on this current build because it is the only one that works.
Here are some details of the current build I am using. (using CPU-Z app)
Model: Oneplus 2 (ONE A2001)
Android version: 5.1.1
Oxygen OS version: 2.2.1
Bootloader: Unknown
Build ID: ONE A2001_14_160226
Java VM: ART 2.1.0
OpenGL ES: 3.1
Kernel Architecture: aarch64
Kernel version: 3.10.49-perf+ (56)
Root access: Yes
Super user app: SuperSU Free v2.46 (Chainfire)
OEM unlocking: Enabled
USB debugging: Enabled
And these are some of the ZIPs and IMGs that refuse to be flashed to my device.
TWRP-3.0.2-1-oneplus2
TWRP-3.0.2-2-oneplus2
Grarak's TWRP recovery IMG for Oneplus2 (modified to install CM13) according to this guide:
missingtricks(dot)net/oneplus-2-official-cyanogenmod-13
cm-13.0-20160924-NIGHTLY-oneplus2
OnePlus2Oxygen_14_OTA_019_all_1606041303_bd42fc5cc5cc4ab2
And also my TWRP backup named 2016-09-16--09-44-09
I am really at a loss as to what to do next. ANY help ANYONE could give me would be greatly appreciated. I have been all over the net looking for ways around this bt have had no luck.
As I've said, I'm not a huge tech head, but I'm not a newbie either. The only thing I can think of is that somehow one of the partitions (maybe boot? ) may have been corrupted somehow when messing around with systemless root. But I don't know how considering it's "systemless". If anyone knows how to check for corrupted partitions on the Oneplus 2 please let me know and I'll try it. Maybe formatting these partitions might help (????), but I don't want to permanently brick my phone.
But I don't know how I've got this particular build working if one of the partitions has been corrupted. And the corrupted partition thing is just a guess.....
Please, anyone, someone point me in the right direction. Again, any and all feddback is welcomed and would be very much appreciated.
This is all Pikachu's fault.

The normal way too update from OOS 2 to OOS 3 is:
Flash the OOS 3 signed flashable zip via TWRP to update the bootloader and firmware
Flash TWRP 3.0.2-2 via your current TWRP's recovery image flashing option
Reboot recovery via TWRP so that you now have a recovery that's compatible with the new bootloader
Wipe data, cache & dalvik-cache (but not internal storage)
Flash the OOS 3 signed flashable zip again to update the system
Flash one of the modified SuperSU zips if you want root
Reboot system
All the files you need are in post #1 of this thread.

Thank you so much Spannaa!
I was clearly missing a vital step here and let it be a lesson to anyone else in this situation....
As Spannaa said......
1. Flash the OOS 3 signed flashable zip via TWRP to update the bootloader and firmware
2. Flash TWRP 3.0.2-2 via your current TWRP's recovery image flashing option
3. Reboot recovery via TWRP SO THAT YOU NOW HAVE A RECOVERY THAT'S COMPATIBLE WITH THE NEW BOOTLOADER!
4. Wipe data, cache & dalvik-cache (but not internal storage)
5. Flash the OOS 3 signed flashable zip AGAIN to update the system.
Again, thankyou Spanna for your quick and accurate response.
The order in which you flash zips and imgs is very important it seems.
You really saved me.
I restored the TWRP backup and I am back to where I started.
Is it now possible to apply OTAs when I toggle the root off in Magisk manager and install using the stock recovery? What do you think would be the best way to do this?
And would it be worth moving to the official build of CM13 for Oneplus 2?
Thanks again, Spannaa. :victory:

Glad you're sorted.
Not sure about Magisk as I've never used it.
CM13 is OK but whether it's worth you moving to it is your choice. Personally, I prefer TipsyOS!

Hi,
I face the exact issue with same Oxygen OS and TWRP versions mentioned, I have tried the above steps but there are some problems:
1. Flash the OOS 3 signed flashable zip via TWRP to update the bootloader and firmware

when I checked the option (Zip signature verification) in TWRP, the installation failed with error "Zip signature verification failed! Error installing zip file '/sdcard/oneplus.zip'", but it's successfully installed when I unchecked (Zip signature verification) option.
2. Flash TWRP 3.0.2-2 via your current TWRP's recovery image flashing option
3. Reboot recovery via TWRP SO THAT YOU NOW HAVE A RECOVERY THAT'S COMPATIBLE WITH THE NEW BOOTLOADER!

second problem is that after installing the TWRP 3.0.2-2 (or above), then reboot recovery, I can't access the recovery again and the phone stuck on bootloop.
any idea ?

I don't have a OP2 anymore but that post was seven months ago and the instructions worked for numerous users.
Don't enable zip signature verification in TWRP - it's unnecessary.
Flash TWRP 3.0.2-2 via your current TWRP's recovery image flashing option and then reboot recovery directly from TWRP.

thanx for replay Spannaa,

I have already did that, but same issue once I reboot "directly from TWRP" , the TWRP doesn't show up and bootloop start again.

Last chance and then I'll leave this for someone that has the OP2.
Are you rebooting recovery "directly from TWRP" or rebooting system?
Is your bootloader still unlocked?

Yes, rebooting recovery "directly from TWRP"
and bootloader loader is unlocked,..
anyway it's not important to fix the phone, it's almost one year since last time I use it, yesterday I saw it in the drawer and try to figure out the issue..,

Issue with Magisk and OTA version 7.1.2

I am having issues getting an OTA with Magisk 15.2 installed. MAgisk Manager is 5.5.3.
1. I did a flash of fastboot rom for the first december update of 7.1.2 without overwriting storage.
2. I unlocked the bootloader
3. I booted (did not flash) to 3.1.1 of TWRP and loaded Magisk 15.2. Everything worked fine.
4. I followed this guide https://github.com/topjohnwu/Magisk/blob/master/docs/tips.md#ota-installation-tips and went Magisk Manager → Uninstall → Restore Stock Boot. I received a confirmation that the stock boot was restored. However, at this point, my google camera still works. This seems illogical if the stock boot is replaced.
5. When I download the second december OTA update I get a failure to install error at step 2 of 2.
Has anyone had similar issues or have solution? If I post to the Magisk threads, what logs will they require and how specifically must I create the logs and where will they be stored?

I didn't get a reply here. Mod, please delete this post. I will add it at Magisk thread.

Oh, wow. I have also installed magisk in the way you have. I hope it hasn't messed with your system. However I'm fully updated so have no way of trying your method of OTA.
Please update me if you do solve your issue incase I also have similar difficulties.

It is no major issue, it is just a pain in the butt to have to flash the fastboot rom to update... It take 15 minutes and a PC if you can't get OTA...
I'm just lazy.

4. restore boot image function will reflash stock boot.img to boot partition, but until reboot you are still using patched_boot.img which is loaded in memory. So you will not lose root access and all Magisk modules work (until reboot).
5. failed update could be due to tampered system partition (it is enough to mount it as RW in TWRP). Reflash fastboot images without data erase and do not modify system in any way afterwards.

Thanks for the detailed reply.. this is the thing that confuses me. The Magical guide clear states to not reboot the phone after uninstalling the patched boot.. so how can the ota possibly pass?

OTA updater verifies system and boot partition (possibly other partitions too) - if they are intact, it applies the OTA patch to unused, secondary partitions. OTA updator doesn't care if your currently running boot image is patched or not, because it's not using files from RAM, but from ROM. Once update finishes its thing (stage 2/2), you install Magisk in backup boot partition, which after reboot becomes active. This is why it's possible to apply OTA while you're rooted with Magisk and you have A/B partition system (as long as you follow the guide).

Android 10, root working

Pretty straight forward for those of us who like a nice clean flash. Not you dirty dogs.
1 clean flash lastest Android 10 factory image and install
2 setup the device don't set a password or pin
Install latest canary Magisk manager
3 pull the boot.img out of the Factory image zip.
4 move the boot image to phone internal storage
Patch boot.img with Magisk.
5 download latest twrp.img and fastboot boot it
Install the patches boot.img to your boot
Mount opposite partition if A then mount b, if b mount a
Ignore the error.
And repeat flashing patched boot.img like you did the first time
Mount original partition reboot. And boom

So installing the magisk canary build via zip in TWRP does not work?
---------- Post added at 04:07 PM ---------- Previous post was at 04:05 PM ----------
Also, did you use .019 or .020 build from the factory image website?

Is patching the boot.img in magisk mentioned in step 4 an option in magisk? How do I "patch" the boot image?
How do I do this portion of step 5?:
Install the patches boot.img to your boot
Mount opposite partition if A then mount b, if b mount a
Does magisk store the patched boot image somewhere (and it tells you where) that is accessible in TWRP? then we need only go to that file path in TWRP under the "install" tab?
What does this mean?:
And repeat flashing patched boot.img like you did the first time
Do you mean on the partition you were originally on?
So if we're on A, mount B, install the patched boot image on A, remount A, install the patched boot image on B, and then reboot?
How do we "install to th boot?"

I used the .20 from the factory. And Magisk saves the patches boot.img for me in downloads, which I can access in twro

Good instructions but you don't even need TWRP if you want to save time. I just patched the boot.img with the Canary. 20 Magisk build and moved it over to my pc so that I could just flash it using the fastboot flash boot boot.img command. Worked like a champ and did not have to disable my security pin and jack with mounting A or B with TWRP.

I just flashed .20
Booted it once.
Then using fastboot I booted twrp, installed magisk 19.3
and Im rooted.

?* lol w.e works ?

Which magisk modules are workings?

Clean or dirty flash of A10?

I just flashed the canary magisk zip (from a booted/not installed TWRP) and it was fine... I didn't go through any extra steps.

hmm so now i have root following these instructions, but i cant seem to do much with it.. i cant seem to make system rw. cant edit build.prop to enable tether, cant edit host files for adaway. those are the two reasons i root, and neither seem to work.
edit: got adaway to work, needed to enable systemless hosts in magisk settings, reboot, then adaway works.

I just flashed the factory image without the -W let it boot. Rebooted back to fastboot, booted Twrp, Flashed Twrp, Flashed magisk 19.3. All modules are working including Adaway except for the active edge mod.

Did the same coming from 9.
What was new for me was the android 'no command' screen; power+volume-up -> menu .
Also had to reinstall Magisk in the manager (19.3), even as it was already installed, to get AdAway (systemless) to be able to alter the hosts.

Adb recognizes my phone and I manage to restart bootloader, but when I try to boot TWRP img it says "waiting for a device.."
What is wrong?

I got tethering working (Verizon grandfathered unlimited plan)
1. Magisk -> Downloads -> MagiskHide Props Config
2. Magisk -> Downloads -> BusyBox
3. Reboot
4. Adb shell -> type ‘props'
5. Select ‘5’ -> ’net.tethering.noprovisioning’ -> y -> y
6. Wait for reboot
7. Adb shell -> settings put global tether_dun_required 0
8. Reboot
Adaway and tethering are my only reasons to be rooted as well. Glad both are working now on 10.

Awesome, yeah I am in the exact same boat as you, thanks for sharing that I will probably take the plunge and root as well. Which magisk version and twrp versions you use?
What kernel if any?

I'm running 10 now with root, I just flashed the latest canary build in twrp, didn't need to modify anything else. I do have a question though, has anybody been able to load up Titanium Backup? It just keeps crashing for me.

This is the way i usually root my device as well.
Flash a fresh rom
fastboot boot twrp.img
flash twrp.zip in twrp, reboot recovery
flash magisk.zip in twrp
reboot.
However after i flashed twrp then rebooted into it, the touch screen wouldn't work. I had to hold power + vol down to reboot into fastboot then i did the boot into twrp.img again and then i flashed magisk from there.
I have no idea why the flashed twrp is not working with the touchscreen. The twrp img and the twrp zip that i used were version 3.3.0-0 and magisk was 19.3.
In Magisk manager it says it is installed properly and that safety net check passes.

Rooting SM-T380 with Pie

I am trying to re-root my SM-T380 after updating to Pie and am following the latest process per [TWRP 3.2.1-1] [ROOT] Tab A SM-T380/T385 - 10/02/2018 but am running into some issues with steps 3 & 4.:
Boot to TWRP
Format the Data partition (not wipe) using the FORMAT DATA button under Wipe options
Install the memory decryption patch
Assume this is the file found in Ashyx's siganture Samsung encryption disable patch but I can't find any mirrors when trying to download it. Is this the right file for the memory decryption patch?
Install the modified kernel
The file for the SM-T380 found in this post appears to be for the T380DXU3CSI5 but the current stock image is T380DXU3CSL2 for the latest firmware installation (Jan 2020 security patch). I assume a new kernel is needed for this latest version. Is that the case? Also, the file is in tar format but need in zip format to flash in TWRP. Is it as simple as repackaging the tar into a zip file instead?
Install Magisk
Thanks for the help!

I will write out what I just got to work with the latest update of Android Pie for the Samsung Galaxy Tab A T380 running T380DXU3CSL2, security patch January 2020. I have tried all of the methods on the main TWRP/Root thread (which is now closed) and only had success with one.
To clarify, yes - using the patched boot.img from ashyx that was made from T380DXU3CSI5 WILL work with T380DXU3CSL2 (latest as of time of writing) just fine. Make sure to flash Stock first and OEM Unlock.
Ashyx does give some files still needed in his/her first post on the main TWRP thread, but the boot image and the DM-verity are buried within a 66 page thread. Out of respect for ashyx's wishes I will not direct link to files. Get TWRP from the first post here. The patched boot image and DM verity no encrypt get from the guide here by user zfk110. Pg. 65 of the TWRP thread. The guide itself did not work for me though. Just grab the files.
So, files you will need:
>twrp_3.2.3-1_sm-t380_oo_4119.tar (TWRP)
>T380DXU3CSI5_patched_boot_111119.tar (boot.img inside the .tar)
>Latest Magisk version here
>Tab_A_2017_Pie_forced+encryption_disabler-1.zip (no-verity-no-encrypt)
Not only have I found RMM Bypass unnecessary, but in my many trials I think maybe it was causing an issue for me. Perhaps someone much smarter than I can explain, but there is no setting in build.prop to need it - I did check.
TWRP/Root:
>Flash TWRP with Odin with "Auto Reboot" setting turned off: (file: twrp_3.2.3-1_sm-t380_oo_4119.tar in AP slot)
>Boot straight to TWRP (home + vol down + power to get out of download mode then as soon as the screen flashes swap to home + vol up + power),
>In TWRP main menu press "Wipe" and the "Format Data", type "yes" to proceed.
>Reboot to TWRP by going back to main menu of TWRP, select "Reboot" then "Recovery"
>Install boot.img to your boot partition from your external SD card in TWRP (there is a YT video how to do this within TWRP if you need help, just Google it. The file you need is: T380DXU3CSI5_patched_boot_111119.tar then extract boot.img from that for TWRP (use ZArchiver or a program that will unzip .tar). It MUST be in .img to install it with the TWRP "Image" button. TWRP won't even read that the .tar is there, and I don't recommend Odin for this)
>Install Magisk from your external SD card (I used the latest, 20.4 just fine)
>Install the DM-Verity Forced Encryption Patch from your external SD card (file: Tab_A_2017_Pie_forced+encryption_disabler-1.zip)
>Wipe Cache and Dalvik
>Reboot to System
Notes:
Boot image must be first before flashing the others. I tried it after Magisk et.al as with a number of people's directions and several other configurations in addition both in TWRP and with Odin (and the other boot image as well on the thread: t380_boot_pp.img - no luck on XSA for me at least) and it caused a bootloop every time. I don't know why. The smart guys are on the TWRP thread but it's closed (and confusing). I just try things.
To the other OP question here - use the later version of the DM-verity patch - the original one (no-verity-no-encrypt_ashyx) you are referring to is a different size and structure (I have it archived) so it is probably necessary to use the Tab_A_2017_Pie_forced+encryption_disabler-1.zip. It's on pg.65 on zfk110's guide that I linked above (though again, the guide itself did not work for me).
Edit: I know someone could find this method out from the big thread but I know what it is like to feel newby and get confused and want to give up. And the number of different methods and files on that dang thread was a bit maddening honestly and frequently in direct conflict with each other.

Thank you for the guide Winston Churchill, I tried following it for my device Samsung Tab A T380 (build T380DXU3CTH4) but I am stuck at installing Magisk. The patched boot.img is installed successfully but when I go to the system and Magisk does not appear so I have to install it manually with Magisk.apk file. Then when I check the status it says "Installed N/A, Ramdisk Yes, A/B No, SAR No" and root is not active.
I really appreciate any help on this!!

Many thanks Winston Churchill, this worked for me after many failed efforts using other methods and procedures.
Just one or two cautions, as I had to go through the process twice -- because the first time I got locked out with an "unauthorized" firmware notice on the first reboot. I'm not sure if it was because I did not flash the RMM Bypass the first time, or I didn't make sure my OEM Unlock was showing after flashing TWRP, etc. At any rate, I ended up with the RMM Prenormal state.
So I started over . . .
- Odin-flashed my Pie version 3CSI5 one more time
- Setup, went through the time and software update thing to get OEM Unlock to show, and enabled USB Debugging
- Odin-flashed twrp_3.2.3-1_sm-t380_oo_4119.tar
- In TWRP, ran Format Data, rebooted recovery and Formatted again (this has been necessary or advised for other Samsung devices in the past, so I did it here too)
- Then flashed in TWRP:
--- (1) boot.img
--- (2) Magisk 20.4
--- (3) Tab_A_2017_Pie_forced+encryption_disabler-1.zip
--- (4) RMM-State_Bypass_Mesa_v2.zip.
- Wiped Dalvik and Cache
- Rebooted to system
- Made sure OEM Unlock showed and USB Debugging was enabled
- Installed Magisk Manager 7.5.1
- Opened Magisk Manager and made sure Magisk was installed (sometimes it takes a reboot to see Magisk, and sometimes I've actually had to go back into TWRP and reflash it).
All good. So I installed my usual root-needed apps, Speed Software Root explorer, Titanium Backup, Adaway and Power Toggles. All are now rooted and working (including Titanium Backup!!!) and my Android Pie appears to be very stable. Soooo . . . quickly back to TWRP to run a Backup in case something breaks!
I have never had so much trouble rooting any Android device before. The T380 is a nice size and very nice weight, but man oh man . . . I was beginning to wonder if I would ever get it rooted. I can't tell you how much I appreciate (finally) finding this thread and specifically your post.

So many conflicting instructions - Why exactly are people flashing this modified boot image and then magisk? Correct me if Im wrong, but isnt that what installing magisk DOES (patches the boot image) when you rename the magisk apk to a zip and install in TWRP? I only FINALLY got this working after I ignored the patched boot.img step completely and simply - flash twrp in odin, reboot rocovery, format data, reboot recovery, flash magisk, disable verity whatever, reboot system..

Magisk patches boot.img for Root access. Sometimes there are also other reasons for flashing a boot.img. I'm not an Android coder so I can't explain every reason why flashing boot.img might be necessary in this case.
. . . "rename the magisk apk to a zip" . . . you renamed a Magisk Manager apk to "zip" for flashing in TWRP? How did that work?
At any rate, my method worked for me and yours (however you actually did it) worked for you. I can say for sure that Android itself can be quirky, for example, my recent experiences with a Galaxy S9 on Pie where, after reflashing the exact same build 5-6 times -- because trying to set a security PIN for some screwy reason kept crashing the system (?!!) -- from one reflash to the next I got different app-disabling experiences. For example, a few built-in apps (like google movies etc) showed the option to Uninstall instead of the expected Disable. The same generic reason why an S8 G950U on Pie v8 can be rooted successfully using @jrkruse's Extreme Syndicate method, and other S8 G950s on Pie v8 will brick. Quirky? Weird, I don't know, can't explain, I just go with the flow as it flows and count my blessings when it works.

Yeah, you can rename the APK to zip & flash it in TWRP
The Magisk Manager APK can now be flashed from within TWRP
Magisk is now distributed as part of the Manager APK, meaning you no longer need to flash a separate ZIP file from a custom recovery.
www.xda-developers.com
However, I spoke too soon... I got it to stop bootlooping and actually got it to boot into system, and magisk manager is installed, but still not rooted. When flashing magisk in recovery again (or even extracting the boot.img & patching it in magisk manager, it recognizes it as a magisk-patched boot.img, but it's still not rooted. This tablet is frustrating the hell out of me, I'm about to say the hell with it & toss it.

As of January last year, okay. On older phones/tabs I almost always go with older Magisk versions that were more current with the older device's firmware.

Just a suggestion, maybe try using an older Magisk. I flashed Magisk v20.4 in TWRP and Magisk Manager v7.5.1 after booting to system. Older Magisk (zip and Manager) can be found on topjohnwu's GitHub.
Note, doing it this way, I always have to reboot one more time to see Magisk fully installed and working.

Install TWRP via official app after you have root with magisk?

Hello there, back in the day (2019 in March or April the phone shipped with Android 9) I rooted my galaxy S10+ Exynos with Magisk and stock recovery (because TWRP method did not exist yet or did but non twrp method looked safer, I forgot the reason)
Then I forgot about TWRP and even upgraded to Android 10 like this:
(standard procedure, download android with Friya, then patch ap file with magisk, then flash it with odin)
Well I used my phone as always, forgot about twrp, but always had a little voice in my head telling me, that twrp is good idea, what if something happens, I would at least be able to copy my data)
So I decided to flash twrp, to ease my mind a bit, and also be able to copy apps to /system/priv-app
So I am using Android 10 (see no reason to upgrade, what I need is there I prefer OneUI 2.0 over later versions and I dont want to make my device slower or loose some obscure api function that I dont even know exists until I need it)
Now, can I just use official twrp app and let it do its thing (I have root), or do I need to download twrp with the app, but prepatch it with magisk before I install it? (I read conflicting info, on xda they say you need to prepatch it, while on twrp guide: https://twrp.me/samsung/samsunggalaxys10plus.html
They say to just use the app if you already have root, so I am confused now
It seams using the app is the easiest and most safe method
Thanks for Anwsering and Best Regards

only in case recovery and boot share the same partition, you will lose magisk after flashing TWRP (does not apply)

well, I gues this did apply to me, because I tried to flash TWRP with the app (latest version: twrp-3.7.0_9-2 that the app offered, it offered 2 files .img or .img.tar, and I chose to flash .img), and now my phone cannot boot, its stuck in download mode it says with red letters
kernel: Could not do normal boot, (DT LOAD failed)
I don't know know what happened, I only flashed recovery, and bootloader is unlocked
adb doesn't work
I cannot even get to recovery
So what now? Can at least flash TWRP somehow back so I can get ot my files (I have most of my videos on an SD card, but 2 or 3 are on internal storage )
I would reflash Android 10 anyway if it wasn't for the files

you can flash recovery.img as tar file but that is useless for backup stock ROM userdata. if you still have the magisk_patched.tar you can flash it to get your data back. don't flash unpatched stock boot.img this will most likely result in data loss.
I would first try older TWRP as DT LOAD failed (device tree) looks like TWRP problem to me.

OK
after installing TWRMP
3.4.0 I got into recovery​
I guess the latest version twrp-3.7.0_9-2 is broken (because I tried flashing from Odin and I got the same error
but 3.4.0 works now
Well then I got into a non rooted android state (I couldnt boot into the rooted one because if I held volume up I just got into TWRMP)
I do have my magisk patched AP file (I did keep that), so I tried flashing it by odin to get into rooted state again, but then got scared because I was aftaid it would delete my data, so pulled the plug out, immediately after I discovered its flashing system.img (it just started)
thats where I interupted it
<ID:0/035> SingleDownload.
<ID:0/035> dt.img
<ID:0/035> dtbo.img
<ID:0/035> system.img
<ID:0/035> __XmitData_Write
<ID:0/035> Complete(Write) operation failed.
<OSM> All threads completed. (succeed 0 / failed 1)
So then phone would not boot, not in TWRMP not in android anymore, so I flashed TWRMP again and now at least
I am in TWRMP (I can see my files, but they are encrypted (they have wierd names but size does seam to match my files)
So how do I reflash android now, without messing with /data partition?
or can I somehow backup just data partition, reflash android and flash /data back?

let the magisk_patched.tar flash, just make sure you don't flash CSC (HOME_CSC is fine it won't erase userdata)

Yey, that did it (that was scarry), now root works, as well as android 10 (for some reason Magisk Manager does not open (but all the magisk modules work)
Now, I did patch this ap file back in the day I updated android to 10 so
I used Magisk Manager 7.4.1.291c718b
and if I remember corecly (thanks got I recorded everything) I patched the AP file for Magisk 20.2-11b7076a)
Now I have Magisk Manager 8.0.7 installed
So after I downgraded my Magisk manager to 7.5.0 it opened
Now I just have to figure out how to install Magisk v21.4 which is the version that belongs to my Magisk Manager 8.0.7, because Magisk Manager won't let me install a custom magisk, it only wants to download the latest version

you can install latest Magisk apk and patch stock boot.img again. Anyway I would do a backup with Migrate and adb pull -a /sdcard first.
or you can paste this url as custom channel and install older magisk if you want to.

aha, I see
is there any other way besides patching my AP file again? (I mean Magisk can clearly update itself somehow)
I mean, Magisk Manager does open (but only version 7.5.0, not version 8.0.7), and I have root its just that I don't have Magisk Manager 8.0.7
So how do I install a specific Magisk version from Manager? (I did try to install like a Magisk module, but now I am stuck in download mode again, so lets install Android 10 again )

look in the json for download link

OK, after I installed Android again (with my older prepatched magisk)
Not sure what happened but now Magisk Manager 8.0.7 opens and says I have 20.2-11b7076a installed
of course as this combo should not exist, magisk Manager cannot see any modules (modules are there in /data/adb/modules and they do work, its just that Magisk Manager cannot see them installed, which means you can not easly delete them and you could install them over and over again, since Manager would not know that they are there)
So now I need to find a way to update to Magisk 21.4
So how would I do that (I tried the module install method before (I downloaded 21.4 from official github release pages) , but that just got me stuck into download mode again, so any other way, is there a patcher for computer maybe?
I mean I can only install the latest version, even if I disable internet, I cannot select a specific version

refer to post #8

Thanks, after spending 3hours to get into magisk I decided to share my procedure (because I forget it a lot)
FIrst: make sure your phones last state was power off (you can eather power off from red button or from recovery)
Then turn phone on and start holding power button + bixby + volume up, and count to 10 then release (not 11, 10, if you count to 11 you will get to recovery)
To try out if you are in magisk mode (without ruining your saved wifi passwords), you can plug the phone into the charger, if it turn on normaly, you are in magisk, if it shows battery charging, then you are not in magisk mode)
OK, I tried updating Magisk with https://raw.githubusercontent.com/topjohnwu/magisk_files/b0694fad86/stable.json
but for some wierd reason, it doesn't want to update, its stuck on 20.2-1
OK,. I tried installing Magisk Manager v7.4.1 and when launching it, it said that it patched dtbo.img and it needs reboot, so after I reboot, I am stuck on download mode again
It sayd: DT table header check fail
well, lets install Android 10 a third time

wait, you're booting into recovery to get into Magisk? you can use Nemesis kernel to skip this.

Yes I am, but its allright, I am used to this
one day I will have to compile my own kernel anyway (to add some drivers to the phone)
Now I have to figure out why Magisk 21.4 won't install
I tried patching my AP file with it, but no matter what I do, I cannot get into it for some reason? (even my trust and tried method does not get me into it, while it got me into 20 all the time)
Is this version broken?
Whats the latest magisk version that still supports Magisk Hide (usefull thing that always worked for me)

With Nemesis kernel no need for button dance, it boots straight into Magisk. Magisk Hide exist up to v23 but there is also unofficial Magisk v25

Magisk needs the ramdisk of the recovery/TWRP to patch it. If flashing a non-prepatched image you will lose root.

Yea, I discovered that already
Now I am trying to get it back and failing
UPDATE: after installing Magisk 23 (last version that has Magisk Hide), prepatching AP file, and flashing it like 10th time, I finaly have root
Do I dare to try TWRP again? (I guess I need to prepatch it with Magisk before I install it with odin? (but which file do I install there are 2 files provided (twrp-3.4.0-2-beyond2lte.img.tar or twrp-3.4.0-2-beyond2lte.img)?

patch the tar file
