Uninstalling TWRP to default recovery? - OnePlus 7 Pro Questions & Answers

I need some root functions temporarily then would like to go back to stock without doing a full wipe. I know I can remove magisk and root but I would like TWRP removed as well because it may cause issues with future app updates that I use.
Is there a way to uninstall TWRP or install the default recovery over TWRP?
Thanks.

Not clear whether you actually installed TWRP and rooted yet, or not. But if not, you don't actually need to install TWRP to root the phone. There are 2 main root methods, neither of which requires TWRP to be installed:
1) Flash patched boot.img to root. This method doesn't touch recovery.
2) TWRP method. For this method, you need to fastboot boot TWRP.img, which is just a temporary "remote" boot of the TWRP image that resides on your computer. TWRP is not actually flashed to the phone when you do this. Installing TWRP to the phone involves (after booting TWRP as mentioned) then flashing the TWRP installer zip, which is purely optional. You can actually skip that step, and just (while booted TWRP) flash the Magisk zip to obtain root. if you do it that way, you have root (with Magisk) but not TWRP (still stock recovery).
In either case, you can use the fastboot stock ROMs to return the boot.img partition to stock using the fastboot stock ROM (as the previous reply also suggested):
https://forum.xda-developers.com/oneplus-7-pro/how-to/rom-stock-fastboot-roms-oneplus-7-pro-t3931424
Be aware, that you can't just flash a stock recovery (by itself) on this device. For A/B partition devices like the 7 Pro, there is no discrete recovery partition. Recovery is a part of the boot.img partition. You therefore need to flash the stock boot.img partition to get back to stock recovery (this should also unroot the phone).

Keep the stock boot image around along with the image that has TWRP and Magisk.
You can swap back and forth just by flashing the boot image.

Thanks for the reply.

In method 2) Does this mean it only temporarily installs twrp. Does this mean after boot TWRP is actually gone and if I boot anytime into recovery or "adb boot recovery" then it will bring me back to the original recovery of oneplus?
For example say I install TWRP via method 2, install magisk and root. Do all my root things I want, uninstall root and magisk, and reboot that means everything is as if I didn't install a recovery or root?

Do I have to pull my stock recovery image or use one of the ones linked?
I have a T-Mobile which I unlocked the bootloader and installed an international firmware. I would like to return to this and not the original T-Mobile firmware.
Thanks again.

Probably better not to think of if as "temporary" installing TWRP. You either install it, or you don't.
If you only do fastboot boot TWRP, and flash Magisk, you haven't installed TWRP at all. It remotely boots/runs the TWRP image that is located on your computer. Nothing is installed TWRP-wise (temporary or not) to the phone when you run this command.
So if you fastboot boot TWRP, and flash Magisk, you will be rooted, but still be on stock recovery.

Be careful when you say "uninstall root and Magisk" since that doesn't specify how you intend to do that. If you mean flashing the stock boot.img, you will remove root and revert to stock recovery. So it is somewhat irrelevant whether you installed TWRP or not.
You will probably also need to delete the Magisk Manager app (to remove all traces of root), as this resides on the data partition, and won't be affected by flashing back to the stock boot.img partition. Keep in mind that this is just an app for managing Magisk. Deleting this does not in itself unroot the phone (some folks get this confused).

To remove root (and TWRP is applicable), you want to flash the boot.img which corresponds to whatever stock ROM when you rooted it. So in your case, the international (unbranded) boot.img, which you can get in the link I posted previously.

By uninstalling I meant uninstalling the app and flashing the uninstall Magisk zip. I was thinking when I do everything I want then fastboot boot TWRP, then flash the Magisk uninstall zip.
Would this work or do I have to flash the boot.img no matter what? or can I also restore the boot section which I will initially backup in TWRP?

That should work. Can't say from experience. I've never uninstalled Magisk personally!
Not to say that whatever changes you made under root will remain. That is a whole different thing, that I can't answer.

Should have the same result as flashing stock boot.img.

Update Rooted Nexus

I am new to this. I have a rooted nexus 5. It is stock rooted with TRWP recovery. I don't have a custom ROM. When the newest update is available, am I safe to update?

Since your post was made today, and the update was released yesterday I'm assuming you are thinking that you will be getting the update over the air? You won't. When you have a custom recovery (TWRP) you won't get OTA's.
But don't be disheartened, not in the LEAST. Unless you've removed or altered the default system apps (you would know if you did) all you have to do is download the update to your phone, boot into TWRP, flash the update, and let the phone reboot.
Due to how the OTA updates are rolled out, even if you had not loaded a custom recovery onto your phone, you might not have had it pushed to you for a couple of weeks.
Read this thread:
http://forum.xda-developers.com/showthread.php?t=2523217
From what you have described you are "scenario 2". Proceed directly to step B. Like many people, I was also step B. It is easier than making toast.
So if I update that way will I lose my data and root? Also do I unzip the file or flash the zip file?

1. If you flash a custom ROM via TWRP it is generally recommended you do a clean wipe beforehand (and before doing that, obviously create a backup). There are cases where you can go straight to flashing without wiping, which is called a dirty flash. Although this is used when you're flashing an updated version of the ROM you're currently running. Following instructions under Section B won't cause you to lose data.
2. You won't lose root because ROMs will generally take this into account. However, if you do happen to lose root, just download and flash SuperSU and you're back on track.
3. Just flash the zip file.

The first part of the reply above is certainly correct, (the rest is also, but I'm just speaking to the first part of it) but I feel it is just going to confuse you.
You did not flash a custom ROM, you flashed a custom RECOVERY. Two different things. When you copy the update onto your phone, in the form that exists in the thread I linked earlier, it is not an entire image. It is an UPDATE to the stock image, which you are already using. As for your concern of losing root, it shouldn't be a concern. As was mentioned in the reply above mentioned, while you are in recovery you can simply just flash SU again.
In fact, I'd be willing to bet the file to flash SU is still on your phone.
As for me personally, I happened to have unlocked the pro version of SU (because why not...it's only $2.50 and I like the app) and just toggled the "survival mode" option. But even if I had not, it would have been a very small thing to loading SU again.
In short, don't worry about losing root. When you first rooted this phone, most of the steps involved were not in rooting the phone, but in unlocking the bootloader. Loading this update has nothing to do with that, so in your case, since you didn't flash a custom ROM (Such as CyanogenMod) and you didn't make any modifications to the system apps...quite literally all you have to do is copy the stuff onto your phone, load into TWRP, fire up the update, and either fire up SU, or have survival mode already enabled, and reboot the phone.
(and no, you don't have to unzip the file pasted in the thread, just copy it directly) The instructions in that thread are really simple, and that's probably giving you a bit of pause, but seriously, it really is that simple in your case, as it was mine.
So I updated but lost root. How do I flash SU?

Do you still have custom recovery cwm or twrp? If so download su zip from either of those posts and flash in recovery if not you can flash recovery with adb or flashify and then flash su zip.

Rooting with Stock Recovery?

Is it possible to root and keep the stock recovery? If so dose any one have a guide?
Can you obtain root without unlocking the boot loader? if not can I lock it after I obtain root?
If i do a full ADB backup can I restore it after I root the phone?
Yes it's possible to root and keep the stock recovery. But you'll have to be unlocked. Put supersu on your device. Then boot, not flash, twrp recovery
fastboot boot twrp.img
When booted into twrp flash supersu
When you reboot your device you'll be rooted with the stock recovery.
Pro tip, I really don't recommend you root with the stock recovery. You can make nandroid backups with a custom recovery and if you screw something up playing with a rooted device you can easily restore it
Likewise, you can lock the device when rooted, but unlocking it will wipe the device if you screw something up.

Now that Android will not apply OTA updates if you're rooted there is really no reason to keep the stock recovery. In the past I would use OTA rootkeeper along with a stock recovery to keep root and still have OTA updates work properly but Google ruined that.
You can relock the bootloader any time you want. Unlocking it will wipe your device though.
Not sure about the ADB question. Typically anything you did to your phone would be lost and your phone would return to the state it was in at the time of a backup though. I have never done a backup in ADB to test what it does to the system partition though.
I forgot about the backup function with custom recovery. The last time I rooted an android phone was a Galaxy s2. What is the latest and greatest custom recovery now a days?
with the custom recovery how would I go about updating the OS if say 5.1.1 were to come out without having to do a clean wipe?

I recommend twrp recovery. Google nexus 5 teamwin.
To up date from a 5.1 to a 5.1.1 I just flash the system, boot, and radio images using fastboot. If it's a bigger version change you'll likely have to flash the whole factory image and deal with the wipe.

Need help updating from rooted 5.1.1

I have a Shield Tablet (post battery fire exchange) and I would like to update it to the newest firmware/os... It is currently rooted, running BitO-Kernel, and stock nvidia rom. I did all the rooting and flashing on this tablet originally, but I never kept it up to date with newer updates. I heard on this forum awhile back that it's not just as simple as flashing a new rom, something about having to flash some other system stuff first or some partition or something. Basically I'm looking for a guide on how to update a Shield Tablet from rooted 5.1.1 to the newest OS version avalible. I tried sreaching the forum, but I couldn't find what I was looking for (maybe I'm not using the right search keyworks).
Agreed, that it is typically best to keep devices updated with the whole OTA update, which include firmware, modems, and whatever other partitions (not always flashed with custom ROMs). Although I'm not sure if there is much changed in those partitions between 5.1.s and 5.2.
That is the original Shield tablet (not the K1) right?
If so, I think you can just download the full OTA zip, and flash in TWRP: https://forum.xda-developers.com/showpost.php?p=72501806&postcount=35
Then root (flash Magisk or SuperSU) right away before rebooting, if you want to keep TWRP. If you don't root, the update will cause TWRP to be replaced with stock recovery.
Another option, if you made a backup of the stock ROM before installing custom ROM (I suggest always doing that) you can restore it, and should get the OTA notification. Then you should be able to just download and update that way. Again, root before rebooting, if you want to retain TWRP.
If all the above fail, you can download the recovery OS, and flash all the components using fastboot, as described in the supplied instructions:

Thanks I appreciate the help! Yes it's an original tablet (not the k1). It's currently rooted with the Bit-O kernel running over the stock Nvidia 5.1.1 os (also has twrp on it as well). I'd like to keep root. I'll have to do some more search to see if I can find the old thread where I was told it's more difficult the a simple flash, I remember it was explained fairly clearly, I just can remember exactly what that was lol.
EDIT: found the original post where I was asking about this from last year, the issue revolves around the Staging Blob which I've never worked with before and know nothing about it (usually just ROMs and kernel flashes and occasionally radio images).

You won't be able to update the OS and keep root. Which is pretty typical when updating most Android devices (root will be lost). But for the 1st and 2nd options I gave (flashing the OTA zips in TWRP), it's easy to just root the device again. Just have your preferred root zip (Magisk or SuperSU) on the phone when you update. Then after the update (before rebooting to OS) while still in TWRP, just flash the root zip. Then you will be rooted, and TWRP will not be wiped (replaced by stock recovery).
3rd option (flash Recoveyr OS in fastboot), getting root again is a few more steps, but still not that hard. After flashing all the components, reboot and verify everything is working. Then go to fastboot again, flash TWRP. Then boot into TWRP, and flash the root file (Magisk or SuperSU).
For any of the options 1-3, if you want to then flash your custom kernel again after rooting, you are free to do so. I'd probably verify the stock OS is working. Then boot to TWRP, make a backup of the stock kernel & ROM, then flash your desired kernel.

On the 3rd option (flash Recovery OS in fastboot), if you go to the link then click the desired version 5.2, it will expand, and you will see Downloads for the Windows or Linux files, and instructions below that. Click on "instructions" and you will see there are steps to extraxt various components, than flash each one individually using fastboot:
fastboot flash recovery recovery.img

fastboot flash system system.img
fastboot flash userdata userdata.img
fastboot flash staging blob
If you do the other methods (flash OTA zip with TWRP) I believe all these components are included, and just flash automatically.

Oh ok thanks! I'll definitely try to flash that 5.2 OTA zip from twrp and see if that works. After that, I should be able to flash any current update (like 6.0) also, correct? And I assume I need to flash 5.2 first before flashing 6.0 (or whatever the most current shield tablet OTA is), correct?

Not 100% sure. It's a full OTA zip, not an incremental update. So in those cases (full OTA) it may not need the preceding update installed. But again, I'm not sure.

I would say that is still true. Don't think you need to wipe anything (except cache and Dalvik - which I usually wipe when flashing anything), and I don't think I did either. Make a TWRP backup, in case anything goes wrong, as well as any other backups of apps, data, etc. (such as Titanium)..
Ask all the questions you like. It's fun to help, although I may not necessarily always know the answer!

Ok thanks. I did just think of one more question, its not 100% related to flashing though... On my shield tablet, I have a 128gb SDcard in it, and I use Folder Mount to move all my large apps and games to the SDcard. Do these backup through TWRP if I check every box (I don't think it does cause there isn't a check box to backup the sdcard)? Would titanium backup work better to backup and restore these large apps & games that were moved with Folder Mount?

You can't backup internal storage or SD card in TWRP.
I don't personally use anything like Folder Mount. I would think as long as the folders are where they are supposed to be, and the data for Folder Mount is preserved/migrated properly, then it will all still work as it did before the update. If you are really paranoid, you can make a copy of the folders on your SD card to your computer as a "backup".

I just noticed on that download link you posted earlier, that Nvidia lists the newest update as 5.2.0, but that is actually Android os version 7.0. Earlier when I said on was on 5.1.1 I meant Android os 5.1.1 (as in Lollipop), not shield os version 5.1 (which is Nougat). Sorry if that wasn't clear in the beginning. Does that effect any of your original advise? Just thought I should double-check that.

I'm not sure if it matters with the OTA. My feeling is, that it won't matter, and it will still install.
My guess is that in the worst case, the OTA fails, and you have to resort to flashing the recovery OS version.

Upon boot, it shows samsung, but then back again to TWRP recovery, cannot go straight to OS.
Please help. I really need to unroot since i wanted to use several apps which detects root/

Uninstaller not working. It looks like the ROM (thor v2) already modifies the boot, so it's not working without root. It's bootlooping to recovery screen. Is it?

Its pre rooted so there is no boot.IMG to revert to. I thought the su uninstaller would remove itself from the boot. Just use a different ROM bro

LineageOS 14.1 on Nokia 3?

Dear folks,
first of all let me thank you for all the good work in here.
I’m quiet used to ADB, fastboot, unlocked bootloaders, TWRP, Custom Roms etc since I've been routing my HTCs for couple years by now.
The other day a friend of mine, owner of a Nokia 3, asked me, if I could possibly “ungoogle” his phone. My idea was it to clean-install LineageOS, since it comes without GApps in first place.
That being said I found some instructions on the internet how to do it – not here at xda though.
I. What I did at first:
I unlocked the bootloader, getting the “orange state”-warning.
I flashed TWRP, removed encryption and installed LineageOS.
Result: Nothing – device wouldn’t boot.
Then I thought I had to relock the bootloader, so that’s what I did and I got the “red state”-error. :angel:
So I ended up flashing original FW with OST. :good:
Ever since that, the bootloader had that “orange state”-warning, no matter what I tried. It is unlocked already. Even flashing the stock boot I found in here gave me that warning. Relocking bootloader fails. But I learned, that “orange state” is still OK. Is that true?
II. What I did next:
I considered if the bootloader is not the problem, maybe recovery is.
So from fastboot I booted TWRP.img, leaving the original recovery untouched, removed encryption and installed LineageOS.
Result: Nothing – device wouldn’t boot.
Since I didn’t really know what the problem was I ended up flashing original FW with OST.
III. What I did next:
I considered that recovery CAN’T be the problem, since it was untouched. Is that true?
So it had to be the bootloader.
I booted original FW, installed Magisk Manager, created a patched boot.
The I booted into TWRP, removed encryption, installed LineageOS, flashed the patched boot.
Result: Nothing - device wouldn’t boot.
Now here it could be the point that my “stock boot” could have been broken in first place already, since it had the “orange state” ever since (see I.) Could this be the problem? If yes, how could I overcome this issue? Flashing the stock boot from xda didn’t help (see also I.) Since I didn’t really know what the problem was I ended up flashing original FW with OST.
IV. What I did next:
I flashed TWRP with SP Flash (Thanks for the wonderful guide @SkaboXD) to keep my locked/untouched/whatever bootloader (again: bootloader here isn’t locked anymore, no chance for me to relock it).
Then I booted into TWRP, removed encryption, installed LineageOS.
Result: Nothing - device wouldn’t boot.
Since I didn’t really know what the problem was I ended up flashing original FW with OST.
Tu sum it up:
I am kind of proud to have reached one and the same goal over many different ways now
But I’ve spent hours of reading through the threads here and trying to find my way and nothing worked. I have never experienced problem like those with my HTCs and could need some serious help now, please.:fingers-crossed:
Q1: Is it even possible install LineageOS on a Nokia 3? That’s what I considered lately.
If yes: How? What am I doing wrong?
If no: What other options do I have to “ungoogle” the device? Root and manually remove all apps? I’m afraid, I won’t find all and that google is hidden somewhere else as well.
Thank you in advance!

no it's not possible currently, that ROM doesn't work. The only way is to manually remove apps. You have my thread about manually removing apps here: https://forum.xda-developers.com/nokia-3/how-to/guide-how-apps-uninstall-t3804425
he can also remove google keyboard if he don't like it, but first install 2nd keyboard then remove Gboard. Location: /system/app/LatinIME
Google Play Store: /system/priv-app/Phonesky
Google Play Services: /system/priv-app/GmsCore
There are also more Google stuff that i am not sure is it good to remove.
If i find a way to remove Google apps completely i will tell you. When i get Nokia 3 again, I will maybe make stock based ROM with debloated apps, build.prop tweaks (that actually work), volume steps mode (without Xposed and build.prop), advanced reboot option (not sure on this one), Vanced YouTube, odexed and many more...
Stay tuned.

Ok, then I wonder, why someone put instructions for the installation on the internet. What's wrong with people nowadays?
Anyways, thank you very much! At least I know, that I can stop my efforts at this point and it wasn't me being stupid :good:
I will stick to your guide. Does it matter, which version I use? 7.1.1? 8.0? 8.1? My plan now is to update to 8.1 since it comes with the highest security patches and then dig through the whole process of ungoogling the device.
Last one so far: Any idea how to get rid of that orange warning in the bootloader? It's not that big of a deal, but if there is a chance to get rid of it I'd be happy.
Your future plans for the Nokia 3 sound pretty awesome. Let me know when you're done - no pressure here.

Yeah, i encountered this too when there was no bootloader unlock guides on xda, all were fake, that's why i first check xda before doing anything.
No it doesn't matter, i used Android 7.1.1 December 2017 Security Patch before i gave it to my brother.
No idea, i think we need to modify some partition like aboot and include some changes but not sure currently.
Tnx for support, i will open a thread where we can discuss about changes you want to see in stock modified rom and advices what else i can do.

Hi @SkaboXD,
to me it seems you have the most knowledge about rooting a Nokia 3 and always give solide answers, so I'd like to ask you directly.
After quite a while now I finally found the delight to spend more time with my friend's Nokia again. I flashed TWRP "successfully" but for whatever reason the phone won't load it. It also doesn't matter which TWRP-version I try. Not even booting directly into TWRP via fastboot boot xxx.img works. Every time I try it starts up stock 8.1. rom.
Any idea why this could be? What should I do? Reflashing the thing with OST again?
I tried that already^^ but when I started my OST-Tool it asked me for some weird login-data? It has never done that before.
Furthermore, once I get over that point, I plan to root it with SU, since I want to have a regular root, not a systemless one. Is there anything special to consider? Or will it be just the regular way
Install/Boot TWRP --> flash SU.zip --> boot device --> boom, you're done?
Sorry for the bother and thank you in advance!

hmm, i think that our twrp is not compatible with 8.1 yet, the only method that could work is flashing Magisk (SuperSU won't work, it's depreciated) with my guide but I'm not sure does it work on 8.1, i didn't tested. It would be easier if i have phone, in this moment i can't help much.

Ok just in general then: I don't give much about the version to be honest. After I fix my OST, I can reflash to 7.1, that's fine.
My thoughts now: Once I'm back to 7.1, I will boot into TWRP, do the whole magisk-magic with patched bootloader and so on...
I) I only know magisk as a systemless root, meaning I cannot delete unwanted apps for example. Is there any chance to get rid of them anyways?
II) I learned when keeping the original recovery, system OTAs are still possible. Will they destroy root?
If yes, I truly need to root at the latest system version possible. Will 8.0 work with root? Or just 7.1?

1.yes you can with systemless root, maybe you got misinformed. In fact i deleted system apps with Magisk.
2.true, 8.0 work with root. OTA will destroy root but you can just flash it again.

Yeah, last time I tried booting twrp I had that same problem, device wouldn't enter recovery
fastboot reboot recovery wouldn't work, eventually I flashed the recovery partition and on reboot held down the power and volume down buttons while the phone was plugged to my laptop before it finally entered recovery

Did you flash recovery with SPFlash? Because I tried to flash it with fastboot, even before I tried to boot into it. Neither one worked out for me.
Which Android version are you at?

No I used fastboot. Oreo 8.1. I think something happens during that orange state message that keeps fastboot from booting into recovery.
One other thing you can try - though it's a long route is:
1. first back up boot and recovery partitions with spflash - very important else your phone might not boot again
2. after backing up the partitions, flash the boot partition either with spflash or fastboot then reboot. You should boot into recovery.
3. The only problem is that you would need to manually patch the boot.img if you want to flash magisk (normally flashing magisk patches the boot partition from recovey) then flash the boot partition with the modified boot.img otherwise your phone won't boot anymore

I've wasted quite some time trying root 8.1 with magisk, but no matter what I did, I always ended up with a softbrick. So you got me hooked up here.
Just to make sure. I flashed FW NE1-215H-0-00WW-B02 (I believe) via OST. (Strange sideeffect here: After flashing the whole new FW with OST, the phone already knew my WiFi and already had Magisk installed, both still from my older installations. I wonder why this is and I have not found a way around it yet )
After the flashed with OST I had two system updates via OTA, so right now I am on Oreo 8.1 stock with security updates from Jan05 '19, in other words: the latest FW possible. What next? According to you:
1. I back up boot and recovery. You mean stock boot and stock recovery, right? I believe my boot is not stock anymore, since it already has that orange state warning. Any way around it? Flashing stock 7.1.1 boot didn'T do any better. Anyways, any other chance to back it up without SPFlash? I have no clue how to back up boot and recovery with SPFlash.
2. I need to flash boot? Not recovery? What should I flash boot with? And then I will have to boot into recovery, like TWRP for example? Any suggestions which one to take? Currently I want to use TWRP 3.2.1-0 by SkaboXD (https://mega.nz/#!qIhFkKia!AkUMvQJ0P...hlCNaZfy2gE4vE) And that is the point, that is not working for me. I cannot boot directly into it, nor can I boot it after flashing. What am I doing wrong?
3. I have to patch boot.img manually. But how can I patch it without having Magisk installed?
Thank you for your time!

Sorry for the delay in getting back to you.
1. Your boot and recovery are stock since its the system update that installs them
Orange state just means your bootloader had been tampered with, it has nothing to do with whether your boot or recovery images are stock
2. You flash the twrp image. Ideally you should flash recovery partition, but in this case flashing recovery isn't working for you. Basically your phone is refusing to boot into recovery. What this method does is force the phone to boot the twrp image
3. If you're not using magisk or su, may I ask why you want to enter recovery for in the first place?
As an aside I just realised that you can flash boot.img from twrp, so instead of manually patching the boot.img, just flash stock boot and then flash your SU or magisk or whatever it is that you want to flash from recovery

Don't worry too much about it. We all have more important stuff than rooting a Nokia 3 to do.
1. Thank you! I've just learned something new :highfive:
2. I flash TWRP to boot partition? I did not think of that, but from what you say it definitely makes sense. And now I see, why I need a backup of my 8.1 stock boot and recovery. Perhaps, I should find out how to backup with SPFlash by now :fingers-crossed: . Too bad, there is no stable Oreo-FW out there. :angel:
3. I actually want to "ungoogle" the phone and therefore, I indeed want to use magisk. But I need TWRP in some way to install it.
Once I have TWRP at boot partition and loaded it, can I flash boot from there? In other words, can boot partition overwrite itself? I doubt it. How about:
a) I create a patched_boot.img right now manually with Magisk Manager, but without installing magisk zip.
b) I use fastboot to flash TWRP to boot and load into it
c) I install Magisk from there and reboot to fastboot again
c) I use fastboot to flash patched_boot.img and reboot the whole thing.
That could do the trick in theory, couldn't it?

I figured the flashing to boot partition one time when my phone kept booting into recovery after a failed ota update. I checked the install script and found out that at one point the boot partition is flashed with the recovery image
You definitely need to backup your boot image unless you want to risk not being able to boot your phone anymore
Flashing boot should be possible, after all even when you boot into twrp you can flash another recovery, in fact when you do a twrp restore especially one that has a recovery backup, you usually overwrite even the partition that twrp is installed on. Your method too would work, but I think it's easier to just let magisk do the job, i've had too many failed attempts at patching a boot image

I MADE IT! :victory:
As it turned out I stumbled over quite some weird different problems:
a) As mentioned, I was not able to boot into TWRP recovery for whatever reason. So flashing TWRP to boot partition and therefore forcing the device to boot it did the trick. Thank you for this excellent advice!:good:
b) When Magisk tried to patch the boot image automatically, it always came up with a boot image of 0 kb in size. Of course, this could not work at all. So, manually creating a patched_boot.img and flashing it after the installation of magisk turned out to be the way to go.:laugh:
c) For whatever reason fastboot had quite some problems with my the device. It obviously kept producing strange, not reproducible errors. So I arranged myself with SPFlash and was good to go.
So now I have a full system backup for Oreo 8.1 stock and a full system backup for Oreo 8.1 with magisk root.:highfive:
I can work my way through ungoogling the device and whenever I screw up, I can simply recover with my backup
So Thank you @redweaver and also Thank you @SkaboXD for all the help!
So Yeah, The LineageOs Version Which is Based on Android Nougat is Very Near For Its Release! Compiled From Source With Nokia 3 Device Tree, Vendor & Also using Kernel Source!
Does anyone know if this build was ever released?
I am not experienced, so if I hit a wall would be stuck, but can follow directions and would like very much to install Lineage OS on my Nokia 3.
