[Q] Uber noob stuck and scared

So I've been reading these forums for days on end now before I touch my phone again. Is my order of things to do correct? (HTC One XL (AT&T))
1. Root
2. Supercid
3. Unlock bootloader
---Currently here---
4. Install CWM/make a backup
5. Relock bootloader
6. Flash a RUU (1.88?)
7. Unlock bootloader
8. Flash a rom
9. Enjoy
As shown above, I rooted, have su on my screen and I can get into the bootloader by vol down+power. I had a scare trying to install RUU 1.85 but I think it failed because my bootloader is unlocked?
Basically everything I do on my phone scares me now. I opened my bootloader today so I can see what stock recovery looked like. I got some weird icons that scared me. I cannot stay where I am because I cannot get OTA updates, and I cannot flash updates myself. HELP!
Thanks, people on this forum are awesome, but you all know too much to be able to write a proper noobs guide.

Those steps are correct EXCEPT for 5, 6 and 7. You don't need those if you're flashing a custom rom, only if you're staying official and using an RUU. We can flash insecure boot.img files now which allow us to jump around firmware versions without blowing up. Just make sure you do a factory reset from recovery before flashing a new custom rom to prevent any weird bugs (you can use Titanium Backup to backup all your apps). Also, I would personally recommend flashing TWRP over CWM. It's a little more friendly in terms of UI and has a bit more functionality baked in.
Edit: And just FYI, the RUU did fail because your bootloader was unlocked. And now you know.

Are you on 1.85 already? If so you are set. But if you aren't, relock the downloader by connecting your phone to your computer via USB in fastboot and typing fastboot OEM lock, upgrade to 1.85 and then unlock the bootloader once again.

Thanks for confirming why the RUU failed. I was scared because it never said it failed or errored. I let it run for 90+ minutes and finally did a hard reset on my phone.
I downloaded Titanium but I don't understand where the backups go. How to save them or how to use them for recovery. I also don't understand how people talk about this phone having an SD card when it doesn't.
I saw TWRP and it looked like the better option but I thought a lot of the roms needed CWM to flash from. I guess I really don't fully understand how to flash a rom then.
This is so weird because I jailbroke my iPhone 3g, and tried multiple roms on my cousins Droid X a long time ago.
Easy question. If you stick with roms, any reason to ever relock the bootloader?
Thanks

I'm on 1.73
As the previous poster said, if I want custom roms I shouldn't even bother with the RUU? Is the RUU just a way to get the most updated factory settings because of root? Also do RUUs cancel root?

1. You never need to relock the bl unless you're RUU'ing
2. TWRP and CWM do the same thing, what you can do with one you can pretty much assume you can do with the other
3. Titanium Backup (I refer to it as TiBu) stores the backup files on your phone in a Titanium Backup folder on your sd card. You use the TiBu app itself to batch restore your apps. So this mean you're gonna have to redownload it manually from the Play Store after a factory wipe. You also have the option or restoring your apps with data and also restoring system data. In my experience, restoring system data is always a bad idea and will cause weird behavior. Restoring app data also sometimes has weird consequences, depending on the app, so I usually just restore my apps without data and individually restore data to apps I know will have no issue and are a pain to set up again.
4. We refer to it as an sd card because it technically still is one, just soldered onto the board.
5. Yes, RUU will get rid of root. It returns your phone to its factory state (except it doesn't touch your user data)

Upgrading to 1.85 isn't necessary since we can flash boot.img and jump between versions

Thank you. I will run a backup from titanium and download it to my computer. Then I will flash TWRP, then try some roms.

You can have TiBu sync to a Dropbox, Google Drive, or Box account too. The scheduling feature is real nice. I have mine running the 2 default scheduled backup tasks every morning at 6am and then automatically uploading to Google Drive provided that I am plugged in and on WiFi.
I have it run every morning just in case I do something stupid during the day.
Oh and make sure to watch your internal storage space. CWM/TWRP backups take up A LOT of space, around 1GB (that's off the top of my head, I know it's around there somewhere). Manage your backups carefully, deleting ones you don't need.

you dont need to bootloader unlock before you upgrade to 1.85. just get the unlock code and then, with a locked bootloader, update RUU to 1.85. then afterwards unlock bootloader with unlock code.bin.

Titanium is just for backing up apps not the entire phone. Sorry if you knew that, it just sounded like you didn't.
You need to flash TWRP and do a backup with it. This will backup your entire phone. In case you ever run into issues you know that you have a backup of your phone from when it was fully functional. This stays on your phone and if you ever need to restore it you do so from within TWRP.

Right, think of a TWRP/CWM backup as the equivalent of a Windows System Restore Point or a Mac Time Machine Backup. It's pretty much a snapshot of your system that you can jump back to in order to revert anything you did that screwed things up.

[Q] How Do I Prep My Device For JB Installation?

OK, so the MotoDev team advised me to return my phone to stock before installing JB, which will be pushed to my phone tomorrow morning...
What do I need to insure my system won't crash?
I have an unlocked bootloader, and am rooted. I already did a factory reset on my device. Some system apps are gone though, as I have deleted them (mostly Google stuff though, nothing crucial). Will I be good to go? (And yes, I will save the SBF and post it, no worries, have a Dev Host account and will upload).

In order to get official OTA updates from Sprint I've always needed to do 2 things:
-Remove Root (eith via OTA Rootkeeper or stock kernel)
-Flash Stock Recovery (OTA has never worked for me w/ custom recovery)
I'd recommend wiping and flashing both stock images in the thread below via fastboot to avoid bootloops and other hassles.

If you want to grab the update package and save it you should prevent it from being deleted. I know that twrp could not install asa14 OTA update when I got it so it was just hanging there in /cache along with md5 (or sha1, I can't remeber) checksum file.
I do not know if there are other ways of saving the update package nor if devs actually need it. But ASA14 got to my bootloader unlocked, gsm modded, rooted stock rom and after booting to recovery it just stayed there, no install happend (I installed it manually) because twrp did not pass the command properly or what ever the reason.
This update is coming from motorola directly, not sprint, right?
Anyway, perhaps someone can give you more accurate details. I personally would flash twrp and see if updated arrives. Because /cache is wiped by the update installer after installation. All automated process. After device boots to recovery it installs the package, wipes caches and reboots, if I am not mistaken.

I believe for the past updates we had the best luck by reverting the recovery back to stock as well. You have missing APKs that you removed so those will very likely be looked for by the update and will fail the update process if missing.
So if all goes well this should be the bare minimum I'd say for getting the update to work:
MAKE A BACKUP, don't want to have a bricked phone yeah? I mean you could have Jelly Bean on it finally... but still bricked...
Revert the recovery to stock if you installed TWRP or ClockworkMod, adb reboot bootloader | fastboot flash recovery recovery.img
Restore any and all apps you deleted from the stock image, either by restoring fully to stock or putting them back manually, wouldn't hurt to do another update check in the play store for them as well.
Temp unroot with OTA Rootkeeper
Download the update, reboot it, do a song and dance, ???, profit.
Now, you might try to restore root asap, it may or may not work, we won't know till we try.... I'm using Superuser 3.1.3 and on their website it claims its for arm devices 2.0-4.1 so maybe it'll work. Your bootloader should still be unlocked I'd imagine, so you can reflash your custom recovery and make a new backup.

why is there no interest in tge HTC A9?

Im just curious, what is the exact reason devs ignore these phones? Is there anything specific that makes them undesirable to work with? I dont think I have seen an HTC device be ignored this much since the HTC Snap?
Like i said... just curious
Cheers,
disco

It's just a phone that didn't really do well in the market, and no one wants to work on a phone that has little buyers...

What I'm wondering is why the Sprint version gets even less love than the out of date AT&T version which at least has a semi-working CM build.

Ok, thanks. Sucks that bad sales numbers can make a pretty decent phone so ignored.
Do you know if M9 or M8 are at all similar enough to A9 to maybe mod one of those roms for A9?

I'm not sure on that one, never worked with either, so it's kind of hard to tell, maybe put up a thread in the Q&A section with your question. And yes it does suck ????

This a copy/paste from somewhere in this forum, but I think its due to these reasons:
With the A9 (and the M9 prior to it), HTC has moved to a block-based OTA system. This means that even mounting system as read-write (as TWRP typically does during startup checks) will nullify the device's ability to take an OTA. Any other changes to the system partition will also cause an OTA to fail (even if that check is removed from the OTA zip) due to "unexpected contents."
Since the A9 has dm-verity enabled and forces encryption by default, root can only be achieved using the new "systemless" root methods. There are two currently working methods:
seSuperuser (this requires flashing only flashing a zip and installing an app from the Play Store)
SuperSU (automatically disables forced encryption & dm-verity, but requires a "Format Data" in TWRP)
There is also no way to take an OTA after you root. However, prior to rooting, you can take a fully untouched system image backup with TWRP, which can be used to restore a fully stock system to the device in order to take an OTA.
How do I backup stock recovery prior to flashing TWRP?
You can't. The "fastboot boot" command appears to be disabled on the A9's ABOOT, so TWRP must be fastboot flashed over stock recovery. The firmware zip included in the OTA will include a usable stock recovery image. That can be extracted and flashed after stock system is restored so that the OTA can be applied.
How do I restore stock system so that I can accept an OTA?
Check the "Mount system as read-only" box in the Mount menu.
Restore stock "System Image" backup (This will only work if you've made a System Image backup prior to making any modifications to /system).
Fastboot flash stock recovery (fastboot flash recovery recovery_signed.img)
NOTE: It is also possible to restore stock recovery via the TWRP GUI. Rename the stock recovery file to "recovery.emmc.win" and place in the backup folder with the stock system image. Recovery will then show as a restore option. MAKE SURE YOU REALLY WANT TO DO THIS, AS TWRP WILL BE GONE WHEN YOU REBOOT OUT OF RECOVERY!!
Reboot to system, install OTA.
What if I have an RUU? Do I need to worry about all this OTA nonsense?
Not if you don't care about losing all your data. If you're S-ON and have an RUU available for your exact variant (model ID and CID must match) and software number (main version must be the same or newer), then you can get back to a fully stock state by relocking (fastboot oem lock) and flashing an RUU. However, if you'd prefer to take an OTA to keep your data intact, the method stated above is how to do so. Or, you can just run a custom ROM and wait for your ROM chef to update their ROM to the latest software (though you'll still have to find a way to update your firmware if you're not S-OFF)
After I go through all this and successfully apply an OTA, how do I make sure I have a clean starting point again?
After the OTA is applied and TWRP is flashed, it will once again detect an untouched system, which will mount system read-only and allow you to make a fully stock backup and start the process over again, this time with the new base.

My ota works fine. Im rooted and you can backup by formatting data partition in the beginning. Fastboot works fine, flashing wirks fine. Really have not had any issues described above.
Oh well

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.

Click on "instructions" and you will see there are steps to extraxt various components, than flash each one individually using fastboot:

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.

Ok thanks again, I appreciate all the help! One last question I promise lol. Do I need to wipe anything in twrp before I flash an OTA zip? In the past I've been told wipes are not required for incremental updates (like 5.0 to 5.1 to 5.2) but they are usually recommended for larger os revisions like 5.0 to 6.0, does that still hold true?

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 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.

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.
