Help. Stuck in TWRP boot loop after downloading latest update OTA

Hi guys,
As soon as I got the OP3 in July, I somehow managed to successfully perform all the steps to get it rooted. I was running OnePlus3Oxygen_16_OTA_013_all_1608061823_765c081a5c8e4dad.zip
OnePlus has been showing me a "new version available" since September, but I very patiently and calmly didn't install it OTA because I didn't want to lose the root.
Finally had a bit of time today, decided I'd finally upgrade. Looked around for the "most recent stable version" and picked this one: OnePlus3Oxygen_16_OTA_035_all_1612310359_e10cadfb2af7.zip
Followed the steps for flashing using TWRP (twrp-3.0.2-1.28-oneplus3) here:
https://forum.xda-developers.com/oneplus-3/how-to/oxygenos-4-0-android-nougut-official-t3529684
It worked. Yay. Then (god dammit **** ****) I still saw this "new version available" and couldn't swipe it away... I accidentally clicked it and it downloaded the OTA. Fine.
Now I'm stuck in a TWRP boot loop. I tried re-installing the OTA_035.zip from TWRP -- I tried restoring my Nandroid Backup (only had enough room to save "Boot / Recovery / System" partitions, NOT data) -- and I tried ADB Sideloading 16_OTA_013.zip.
I'm stuck rebooting in TWRP 3.0.2-1.
Is there anything I can try before going ballistic and wiping my data?
Thanks.
Marc

Have you tried the newest blu-spark twrp? https://forum.xda-developers.com/devdb/project/?id=15934#downloads

Hey Puddi_Puddin, thanks for replying.
I never heard of blu-spark, but gave it a shot. Even though the guide seems to apply only to OP3T: https://forums.oneplus.net/threads/...-or-custom-recovery-without-data-loss.479265/
Anyways I flashed blu-spark with ADB. Booted into blu-spark. Wiped Dalvik/Cache, re-installed OnePlus3Oxygen_16_OTA_035_all_1612310359_e10cadfb2af7.zip, wiped Dalvik/Cache, rebooted -- keeps booting into blu-spark TWRP.
Get the "device unlocked" error screen, then the dm-verity error screen, then the OnePlus logo for about 2 seconds, and then back to blu-spark. Repeat ad nauseum.
What state is my device even in? I wouldn't call it bricked... I assume it's still rooted, bootloader works, I can flash different TWRP versions, ...
Any other ideas ... ?

After you've flashed the full zip, flash also the latest stable version of SuperSu (2.79) and latest TWRP from @eng.stk (the v11, it solves the dm-verity error). Then reboot to recovery, it should appear TWRP and the error should't appear.

There are quite a few versions of TWRP from eng.stk (bluspark). Which one did you install? Try version 11 which is supposedly for N or 3.0.2-19 or 23.

Thanks for your help everyone.
I downloaded SuperSU-v2.79 here http://downloadmirror.co/Utz/UPDATE-SuperSU-v2.79-20161211114519.zip
I flashed both ZIPs OnePlus3Oxygen_16_OTA_035_all_1612310359_e10cadfb2 and UPDATE-SuperSU-v2.79-20161211114519.zip

Still see dm-verity error ... still keeps booting into blu_spark TWRP. :crying:

From where have you dowloaded the OTA? XDA or OnePlus forum?
I saw a thread regarding the OnePlus 3T update some post above, if you've downloaded from there you've made a mistake if you own a OnePlus 3.

You mean 3.0.2-19 or 23. Not blu_spark, right? Ok I tried twrp-3.0.2-23-oneplus3.img from here (https://www.androidfilehost.com/?fid=529152257862684308)
I tried flashing my old images I used last year (I just wanted the phone to boot into *something*) Oxygen_16_OTA_013 & SuperSU-v2.74. Managed to boot. Updated 4 Apps (??) But as soon as the login screen came up, it would reboot ... and keep looping. So I couldn't use the phone, but at least I managed to boot into something other than TWRP.
Next I tried to reinstall OOS4, 16_OTA_035 with SuperSU-v2.79 SR2. Still get the verity error, but at least I managed to boot! But - the phone is *super* buggy/unusable... SIM cards aren't working - I can't access my options screen - and "Developer options are not available for this user".
Now from my "About" screen I have OOS 4.0, Android 7.0, Kernel version 3.18.31-perf+ [email protected] <-- (that's from my TWRP version. right?)
Did the OTA I install from OnePlus directly screw everything up? For that brief moment before I installed it, I tasted a seemingly properly working OOS 4, so I know it's possible...
A few lessons I've learned are -- I can use any recovery (TWRP) to use MTP and flash files and stuff... but in order for the phone to work properly, I have to a) flash the SuperSU (not just the ROM) and b) make sure I have the "correct/proper" TWRP (kernel?) matched with each ROM. Is that kind of right? That's where I'm stuck I guess.

I'm currently backing up my data, and I'll attempt to follow these instructions to switch to f2fs (hopefully get rid of the verity error) and install OxygenOS 4.0.1 (http://otafsc.h2os.com/patch/amazon...n_16_OTA_037_all_1701041839_aa64b084a40a4.zip)
I'm also a bit confused about the best version of SuperSU-v2.79 to use, because blu_spark was writing somewhere (can't find where) that SR1 and SR2 were the cause of battery issues ... So yeah, I've got other things to try, but should the ROM from OOS4.0.1 work with any of them?
THANKS.

Unfortunately I haven't tried to update the phone yet, so I don't know what else you can do. But you can also follow the guide posted by @Viper The Ripper here:
https://forum.xda-developers.com/showpost.php?p=70499899&postcount=5
I think that it's simpler and I'll follow that one this weekend when trying to updating my phone

In my opinion, the only thing you can try is to make a data backup from recovery to any external storage (like a pendrive) by Otg, but it takes some risks. In case this partition has been damaged, you can get issues when you install the rom.
The safest you can do is clean installation in spite of you lose data so, full wipes and a new full rom.

You have to install stock recovery, and then reboot into recovery, you will have a instalation error, reboot and loop solved Then, you can flash your twrp and su without loosing data
I discovered following this threath desesperate and going to do a clean install, dowload the files and try to do it steap by steap: https://forum.xda-developers.com/oneplus-3/how-to/fix-device-mapper-verity-simple-trick-t3530685

Hey Satisastur,
Thanks for taking the time to comment. Yes, actually that's exactly the guide I wanted to follow. But I'm stuck before even starting -- if I make Nandroid Backup now (in ext4) I can't load it back once filesystem changes to f2fs -- isn't that right?

Yes, I was on f2fs before this happens, so I only have to install all without formating data. You should do a manual backup to do that, once on recovery, you be able to enter phone data partition from windows. Copy all folders you want to save before formating to f2fs in recovery. Other setup and configuration like ringtones and stuff, all cache and configuration of apps, wallpaper, led, colors and themes... you will lost it. I don't know how to backup that, but its the worst part of formating data... google backup doesn't save all the config
You will start with the android phone start menu, like new, with new dactilar and patron security, etc...

Try TWRP 3.0.2_19 and Supersu 2.79 stable. For some people this works and according to eng. stk, only Supersu 2.79 stable is compatible with N.

Understanding how DM-Verity is triggered - How to update easily 4.0.x -> 4.0.x+1

Hey there,
I have been really annoyed since i installed OOS 4.0.0. First because it took ages the first time to get it right, and then because i had to start from scratch with every little 30MB update AGAIN.
I didn't find any reliable source to what happens in the folowing cases, thus this thread :
1- Flashing official recovery + updating through android
=> Will it work/DM-Verity error appear ?
2- Flash official recovery and sideload OTA/Full ZIP
=> Is /data getting wiped ? Same question about DM-Verity
3-Flash full Zip in latest eng.stk TWRP followed with supersu
Has anyone explored these solutions ?
Thanks in advance
EDIT: Working way for updating:
1: Dirty flash full ROM in latest modified TWRP
2: Flash SuperSU WITHOUT booting into system
3: Wipe dalvik/cache
4: reboot to system.
For explanation about what triggers DM-Verity check out post 19

DM verity is triggered by the firmware. You can't avoid it unless you want to run old firmware
It is not an error nor a bug - it is a notification. There is no impact to performance

update everything (ROM/TWRP), flash old (non-4.x) firmware
FYI you're fixing an aesthetic issues and there may be more bugs from using the old firmware.

I don't have the issue right now with a 4.x firmware ... You are not helping... My guess is using OnePlus recovery and updating through android there wont be a DM Verity message. Do you know if this is true ? If not you aren't telling me anything i do not know.

if you use stock recovery you won't get the dm-verity notice either.
not sure why you mentioned eng.stk TWRP if you're not trying to run TWRP.

Thank you for answering, but seriously, did you even read the first post ?
So i can flash OnePlus firmware, update android within the system and then flash twrp again. With no DM Verity appearing ?

no - it's not the flashing process.
DM verity notification will always be present while you have TWRP (unless you go back to old firmware)

Im getting tired of you ignoring what i say.
I'm on OOS 4.0.1. I did a clean sideload through OnePlus recovery, and flashed twrp/root afterwards. No DM-Verity. I DID NOT flash an old firmware.

it's a compilation of things not just one thing, the firmware thing is just the easy way out, if you decrypt the phone data (just wipe it) and rooted then re encrypted it, you wont get the dm verity issue...
so simply, sideload or flash the full rom , if you sideloaded immediately fastboot TWRP (the latest official or modified) , then immediately flash SuperSU... reboot to system, no dm verity will appear.

Did a clean flash (beta 10) with the stock recovery, flashed TWRP with SuperSU afterwards.
No dm-verity.
After dirty flashing beta11 full zip + SuperSU through TWRP the dm-verity screen is still NOT there.
Btw, this has been already discussed weeks ago.
Do your homework.

dm verity is a fail safe present in system boot.img . Nothing related to firmware. Don't know from where people getting all this hoax

it's the worst way to "fix" the issue, you're using an old firmware that's more than likely have incompatibility issues with the OOS updated rom, so unless you're using a custom rom (not OOS or OOS based) where it doesn't matter what firmware you use it's not a recommended practice.

Neither flashing twrp, nor OOS would trigger dm-verity (unless you already have that message)
If you however boot into system, dm-verity will be triggered. The idea is to patch that before it gets triggered.
Flashing SuperSU patches DM verity. Which is great if you want root access. Again this patch won't work if you already have dm-verity warning. Once you flash the ROM, do not boot into system. Flash SuperSU 2.79 or above and verity will be patched. You will also see a line "patching dm-verity" in SuperSU installation process. Now verity message won't appear.
If you don't want root, there is a no-verity zip that you can flash which will have the same effect. I use SuperSU so I don't have any links to this but Google is your best friend.
- if you already have verity
- if you forgot patching verity, booted into system and now warning screen has appeared.
Now here is where things get tricky. Boot to fastboot, connect phone and type
fastboot format userdata
Remember the above step will wipe internal storage completely
Reboot to recovery
Format data (not wipe but format. This step is very important)
Flash OOS
Flash SuperSU
Reboot to system. Now there will be no dm-verity warning

@ungeeked great detailed explanation that should put an end to all chatter TBH your reply should be pinned in this section for some while and titled DM-Verity explained.

Anyone successfully rooted SM-A520W?

Hey everyone,
I have been trying to root my new Samsung A5 (A520W - Canadian variant) but nothing seems to be working.
My first method was to flash CF AUTO ROOT with Odin, but this just rebooted the device without any sign of changing anything - no superSU installed and RootChecker returning negative results
I then flashed TWRP, and from there tried installing both SuperSU and Magisk v16.0, both of these options made the phone unusable (verification error on boot) so I flashed back to stock firmware and now I'm out of ideas.
I've tried looking for guides on the SM-A520F (non-Canadian variant) but most of these are out of date with respect to the recent OTA upgrade to nougat and/or mention the CF AUTO ROOT method which I know doesn't work
has anyone here managed to root this device? Am I missing a step, like formatting/wiping data beforehand or something? is it worth downgrading to an earlier android version?
Cheers!

Format data with the FORMAT DATA button first in TWRP then immediately flash Magisk (preferred) or latest Supersu.
Reboot.

I have done it! Had the same problem and yes i have the Canadian a520w. I had to use Odin and then install superuser
Step one: Is to download Odin on pc mac or linux.
Step two: download superuser on your phone then move the file from your phone to
you computer.
Step three: open Odin and select the superuser zip file and it should say pass.
Step four: install root checker off Google play
This is not a full tutorial on how to install it but all you need to search is how to use Odin.

Please excuse my being a layman in this matter. I tried tot flash superuser.zip using ODIN but ODIN does not even see zip files (it only recognizes some other formats like .tar, .img etc). Could you please give a little more details on how you flashed superuser.zip using ODIN?
Thanks a lot in advance.

Hi jermzii,
I apologize for my questions - I am not very experienced in all these. I would like to ask you a few questions:
Where did you get an appropriate TWRP version for SM-A520W?
Also, ODIN, does not "see" zip files. How did you flash the supersu.zip using ODIN?
Many thanks for your help in advance.

I just bought a Canadian A520W with with stock Nougat (Telus firmware A520WVLS2BRD2). I tried to root it using CF autoroot and TWRP and I had the exact experience as the OP dan.tjones. There is no TWRP specifically for A520W. After trying several versions I found one which is successfully flashed with ODIN (TWRP 3.2.1.0 for A520F). TWRP appears to install Magisk (latest version 16) successfully but it shows no root or su binary. TWRP also appears to install SuperSU zip (there is a specific version for A520W nougat) successfully, but when I open SuperSU app, it says the SU binary is occupied. Google shows two "fixes" ((1) clean uninstall using an option within SuperSU, then reinstall, and (2) uninstall SuperSU + install an earlier version of SuperSU then updating the binary (hangs). Both fixes do not work. Someone mention wiping DATA in TWRP would fix the problem, but it did not work for me.
The major problem seems to be KNOX keep saying "failed verification". At one point it was so screwed up that it just boot-loop / hang and the only thing that work was download mode. I install TWRP again and it sticks. Then I wiped everything (cache/ Dalvik, data, system, internal storage). I probably could try to flash the stock nougat firmware using ODIN, but it was still downloading (snail speed free download).
Since there is no more OS in the phone, I manage to install a 6.0.1 pre-rooted custom ROM using TWRP (I originally intended to downgrade from 7 to 6.0.1 anyway because of reports of poor battery life), and installation was successfully, giving me root. BTW I originally tried to downgrade from stock nougat to stock marshmellow using ODIN, but it does not work ("failed" message).
The TWRP version that I flashed with ODIN:
TWRP 3.2.1.0 for A520F ("recovery_a5y17lte-080318.img.tar")
https://androidfilehost.com/?fid=890129502657588962
The 6.0.1 custom ROM I installed with TWRP:
AXES ROM v.1 (they did say it is compatible with A520W)
https://forum.xda-developers.com/samsung-a-series-2017/development/rom-t3606231
I did not find any nougat custom ROM suitable for A520W. I am happy that I can find a rooted ROM and it does not matter to me whether it is marshmellow or nougat.

You have rooted the device successfully the first time when you flashed magisk.Just root manager app was not installed.
If you have screwed up your device, do a clean flash of OS...then flash twrp and after flashing magisk the binary would be flashed but the app would
not be installed.To do that extract the app from the magisk zip that you flashed.It must be in common folder inside the zip.
Dont flash binaries on top of binaries.
Hope it helps

Hey Sir!
Soooooo I've been messing around with this all night and I figured it out somehow after nearly frying my new A5 (2017) lol
I'd recommend that you follow the directions as best you can and as fully to help you not have to redo all your software settings and stuff like I did haha. I think if all this is done in this order you shouldn't have to lose your data. I can't guarantee anything but figured I could share what worked for me. BONUS: I actually don't have an unlocked phone and I'm still locked to my carrier actually! So I don't think all these warnings are necessarily valid. Anyhow, hope it helps. :laugh:
NOTE: I'm not allowed to post website links here for some reason haha so sorry for the inconvenience! All the sites began with the https colon double slash btw! So MAKE SURE to add that to the addresses below (links are in italics)!
FIRST: Completely backup phone using Android Studio as can be found at Tech Republic website /article/how-to-create-a-full-backup-of-your-android-device-without-root/ . Also I'd recommend you do a Smart Switch full backup. Smart Switch will work to some extent and I personally restored from there pretty intact as I didn't have the Android Studio backup option before my phone got wrecked by the Verification error after I attempted to flash SuperSU onto the phone using TWRP.
1. BEFORE ANYTHING ELSE: Enable Developer Mode (by tapping on the Build Number several times), Turn OEM unlock on, enable USB debugging, and make sure all the "factory reset block" is off (or Allow factory reset option is on) and encrypted data features are off, I unlocked any Notes and disabled Secure Folder and Knox and Samsung Pass
2. Turn phone off
3. Boot phone into Custom OS install mode by holding Power+Volume Up+Home
4. I downloaded a TWRP installer file from tx5.androidfilehost.com/dl/TLLV1I5jSqS9Zg68RNh1hA/1538776061/890129502657588962/recovery_a5y17lte-080318.img.tar
5. Download the Odin software to flash TWRP onto your device, I got mine from drive.google.com/file/d/0B-2yp-J_x0LPaGJrSUlUcHE1a2s/view
6. Used Odin 3.1 to flash TWRP onto Recovery using the AP function, also turned Auto Reboot and F.Restart off (unchecked boxes)
7. Downloaded (newest file that's a zip) such as no-verity-opt-encrypt-6.0.zip from build.nethunter.com/android-tools/no-verity-opt-encrypt/ and put it on the SD card in the phone
8. Turned phone off and booted it into Recovery Mode by holding Power+Volume Down+Home
9. Used TWRP recovery to flash the no-verity-opt-encrypt-6.0.zip which sort of disables all the security things on Samsung (such as Health and Pass and Auto Updates) that would block your work, and this actually lets you reboot your phone instead of getting the Verification Integrity Check failed error and having to reset your phone every time.
10. After rebooting my phone, everything was running fine. I then downloaded SuperSU file SR5-SuperSU-v2.82-SR5-20171001224502.zip from download.chainfire.eu/1220/SuperSU/SR5-SuperSU-v2.82-SR5-20171001224502.zip?retrieve_file=1
11. Used TWRP in Recovery Mode to flash SuperSU onto phone from SD card and hit Reboot. Slight boot loop was visible and then the phone restarted normally with SuperSU installed and full root access. Thanks be to God.
Again, I can't guarantee this will work BUT it is the first walkthrough that I know of on the web. Hope it helps at all!

Edit:
Originally gave up on this, but recently managed to flash TWRP.
Now in Verification Error on boot, and trying to flash the no-verity to get around that.

Success (almost rooted, but shouldn't be much harder)
Just flashed a custom OS using Odin_3.12.3, twrp-3.2.3-1-a5y17lte.img.tar, lineage-14.1-20181117-nightly-a5y17lte-signed.zip, and open_gapps-arm64-7.1-pico-20181204.zip.
With help from this discussion, the LineageOS wiki "Install LineageOS on a5y17lte", r/LineageOS "Heimdall Failed to send data" (a post by noahajac was very helpful. You'll find it soon after OP), and the Odin install guide.
Some problems I encountered was that heimdall isn't favoured for this, and that if you try to wipe your partition through TWRP and it says it couldn't mount /data, you need to format the partition before wiping it.
Edit: so upon using the phone for a bit, it became evident that the SIM card was not being detected. From what I've read so far, this is because the phone had Android Oreo and the LineageOS was for Nougat. So I will have to restore and then revert to a Nougat version of Android and try again from there...
Not gonna be finished tonight. As long as I can get the restore and cell service working...

Two Questions re: rooting the SM-A520W
1. How can I make a proper Nandroid Backup. Everytime I go into TWRP the /data partition is unavailable. Yes I formated it and flashed no-verity-opt-encrypt-6.0.zip but it still is Zero bytes.
2. After rooting, the Fingerprint scanner becomes non operational and the lock screen password/pin does not work (keeps asking for the same password/pin over and over even though they are correct.)
Thanks for the Help.

Problem 2 Is still there I seem to remember I have to replace Samsung Pass and Samsung Account, but I don't know where they are located I think I am supposed to create a directory in /prv-app I don't remember

Root and Magisk on Oreo (oct security patch)

After using this phone for a while I decided to root it.
I unlocked bootloader, installed TWRP and flashed Magisk, but all I get is bootloop or stuck on bootlogo (your device has been unlocked.....)

64bit 3.2.1
and TWRP and modified magisk from https://forum.xda-developers.com/z2-play/how-to/guide-twrp-root-t3667769
I tried all TWRPs with both modified magisk and official v18.

I did 3.2.3-0 TWRP method (by Junior Passos) on my XT1710-06 device with 8.0 on August 1 security patch (purposefully neglected updating any further cause method was tested exactly up to August patch according to Passos) and everything seems working pretty fine for a month now. Think I've installed no Magisk modules other than Xposed systemless yet and I've no interest in SafetyNet as well, so not deeply tested either. Don't know for sure, but I guess there's a good chance for such method to work on October patch too. Just be sure to perform every step as it is now in the 3.2.3-0 OP. One word of advice: after performing TWRP backup, look for it in /system/media and move it to both external and internal SDcards just in case something goes wrong (usually because of a missed step, I can say)... Also: I recommend to install Magisk v17.1 first time; then, if you want, update to v18 but right from the installer...
Sent from my Moto Z2 Play using XDA Labs

Strange, I have zero magisk problems when using the latest stock rom. Flash in twrp, done, no issues. However, it could be because I first back up boot and system and then restore them with twrp before rooting(this removes encryption).

Have these steps worked for me...
1.)Flash TWRP using Fastboot
2.)Go to TWRP/Settings and open Terminal.
3.)Run both of following commands:
echo KEEPVERITY=true>>/data/.magisk
echo KEEPFORCEENCRYPT=true>>/data/.magisk
Click to expand...
Click to collapse
4.)Flash Magisk-v17.1.zip
5.)Repeat step 2 and 3 dont wipe.
6.)Start
NOTE: before Reinstall stock or uninstall Magisk.

I did the Junior Passos method of doing the backup, and everything is working like a charm.

It's not what rom but, how you do it. When on stock ROM, it is encrypted so you must first back up system and boot and then immediately restore them, this remove encryption. Now flash magisk and it will work.

Flash or Boot into TWRP
Backup System and Boot partitions in TWRP
Restore System and Boot Partitions in TWRP (note I had to enable R/W access in TWRP to restore the system partition)
Flash Magisk-v19.3.zip
Reboot
That is it. Now Rooted and passes all SafteyNet test. No more restricted apps. Even Google Pay now works.
Thank You.

This worked great, thanks. Only issue I met was that I couldn't see the OEM unlock switch, so it didn't let me to flash TWRP from Odin (even though it was already unlocked), giving me "only official released binaries are allowed to be flashed(recovery)" error.
The solution for that was following these steps: https://www.xda-developers.com/fix-...y-s9-samsung-galaxy-s8-samsung-galaxy-note-8/
EDIT: no wait, maybe it's bootlooping.
EDIT2: yes it is. I'm using italian carrier, you?
EDIT3: at the end I created a custom boot.img by using Magisk and I flashed it. In this way I kept encryption and stock recovery, but this doesn't give me write permissions in /system. But I do have root.

EDIT3: at the end I created a custom boot.img by using Magisk and I flashed it. In this way I kept encryption and stock recovery, but this doesn't give me write permissions in /system. But I do have root.

I got it to work on a Bulgarian unlocked model
Maybe try flashing the twrp flashable firmware after the mod

omg it was so easy!
after you flashed twrp and formated data you just have to flash magisk and that's it

I done that, but still stuck on SAMSUNG logo, no boot loop or what. I was waiting 10min, nothing happened.
Any advice?

Hi there,
after having tried different methods to root my S9, which has updated to Android 10 One UI 2.0 this morning, maybe the solution that finally worked for me will help you too.
First I tried to root just like in Pie, as found on the net: flashed TWRP 3.2.3 via Odin, then flashed Magisk with TWRP plus this no-verity-opt-encrypt. Got stuck in bootloop, tried different no-verity/dm-verity versions, Magisk 18.x and Magisk 20.1. Nothing worked, got stuck again every time i rebootet the system again.
Then, after realising that I CANT get back to Android 9 (old rom wasnt Odin flashable anymore, phone didnt boot, BSoD), I first downloaded the new stock rom and bootloader as zip, got it from here:
https://forum.xda-developers.com/showpost.php?p=81615561&postcount=1830.
You have to check if that fits with your version / phone. Once downloaded, I copied both onto my SD card. So now I was able to install at least the new clean stock rom. Oh, and now I used the TWRP version 3.3.1.
Then I found this:
https://forum.xda-developers.com/galaxy-s9/development/root-s9plus-exynos-android10-t4065343
At first I tried to root without the SoLdieR9312's mod, only with MAGISK 20.3 and no-verity. Stuck again, it only bootet to download mode, nothing else. So flashed again the clean stock rom, and after first not keeping the right order (I suppose) I finally followed EXACTLY the instructions 1 - 4 in above manual including SoLdieR9312's mod (I highly recommend first a complete Wipe, format data, and then flash the clean new Rom with Android 10 and bootloader from above link).
Now, to save you the time I spent today: once your phone is bootet (and succesfully rooted via Magisk 20.3, which will happen automatically due to the SoLdieR9312's mod), DONT LET MAGISK UPDATE TO VERSION 20.4!!!! Magisk Manager asks you to update, but when I did update to 20.4, everything fell apart again, it only bootet to download mode.
Now I seem to have it stable and running with 20.3 and the [email protected]. I rebootet 5 times so far just for the sake of it, and it works fine and rootet.
If I can be of further help, please let me know. I spent the last 12 hours on this matter, so dont hesitate.
Greetz from me minus a bunch of nerves
PS: After I wrote the above, I deleted the Knox family in the rootet system, and then it collapsed again and, after BSoD, it only rebootet into download mode. I can not exclude the possibility, that this might have been the reason for some system breakdowns before, as I had to re-do the wipe-clean-install-then-root-then-customize worksteps aroung 8 times yesterday before it was stable as it is now. Now I´ll leave Knox on it, though that itches me a bit. But I´m exhausted for now
PPS: IMPORTANT when I try to create a PIN or a pattern for the lock screen, phone reboots to SIM card PIN screen and then keeps rebooting and rebooting. It looks like there are some interferences with root and PIN / security. I did NOT create a Samsung account, only a google one, cause in the beginning i suspected it might have been a Sam acct problem (I constantly couldnt log into it on the phone). Turns out that might not have been the case, rather a prob between root and setting a lock screen security.
