GEM-702L, want to get rooted marshmallo installed. Screwed something up

I will try to keep it short and concise;
Had android 5.0.1 (if I recall correctly), unlocked it, installed twrp and rooted it.
Then used the local update option to get to marshmallo. Then tried to root again using supersu and it wouldn't boot. Tried restoring nandroid backup of 5.0.1 backup but it wont boot either.
I have searched for many hours and tried many different roms etc. I can only get to the boot animation and it just stays there.
I can get into TWRP and bootloader with no issue but have no idea if I can use the dload option if I can not boot into the OS.
Can someone please help me get this back either to the stock rom or a custom marshmallo rom installed?
I will be honest that I don't fully understand what it means when there is a prerequisite of "You must already be on B201 or higher to flash this" such as with the Simply International I have tried to flash. And am not sure what the EMUI version is or how it affects what can be installed.
Thanks for any info.

Hello
1) First of all, go into TWRP recovery, and do a full wipe. Then reboot and wait.
2) If unsucessfull, try out the downgrade file for 702L : http://download-c.huawei.com/download/downloadCenter?downloadId=81363&version=323452&siteCode=tw . It does install with official dload method
3) If it's not enough, you'll have to use ADB to fix your device I guess:

B394 update advise

Hi guys
I really need some assistance, just because I received a notification for update my honor 8 L09 from B389 to B394.
I'm not sure because the device has the bootloader unlocked and it is rooted now, so i'm really afraid to mess it up!
Should i do the update?
Thanks for the help in advance.

Well I'll tell you how I updated my Honor 8 L09 from B389 to B394 and you decide if you wish to proceed. What you get with update is probably new security patch (you are currently on May I assume? And get updated to August 5th) and some minor changes.
So I updated same way as I did the update before (B381 to B389). I was rooted and bootloader unlocked same way as you currently are now, stock EMUI. First what you must do is a full TWRP backup because there is a high chance your bootloader will relock and you will have to restore data partition on your updated device, or at least that's how I had to do it.
To update you need to extract stock recovery.img from B389 and flash it via fastboot. After that you download full update image via
Settings > Update Device and confirm that you want to update. After that device will reboot and you'll be booted to recovery where update will take place. Once that finishes your device should reboot and if you encounter the same scenario as I did you will find yourself with fully locked bootloader. You won't encounter the "Your device is unlocked and bla bla black screen", you will go straight to the system and your device will be unrooted.
What I did after that is go to the fastboot to confirm that my bootloader is locked and indeed it was. I was unable to flash my TWRP recovery again. So my only solution to rooting and having TWRP again was to unlock the bootloader once again. You know the drill for that... Enter "fastboot oem unlock xxxxxxxx" and confirm the dialog. Get full factory reset, and reenter the fastboot to finally reflash TWRP. So assuming that you made the backup now all that has to be done is restore only DATA partition. And not to forget flash latest SuperSU zip. Of course I recommend you wiping dalvik cache or not restoring the data partition at all and starting from the beginning on your new system just so you have a clean start and no unexpected bugs even if I have none personally.
That's it. Some people reported different scenarios while doing this update. This is only how it went for me and your situation might be different so ALWAYS do backups.

First of all thanks very much.
I'm really confident that is too much work for so few improvements.
I guess i will wait for Oreo update and the corresponding Emui version, and at that time i will get my hands busy!

I updated from B392SP02 super-easily via ota without losing root or my bootloader0unlock but beforehand I flashed the modified recovery that doesn't verify update files. (available in one of the threads here) Give that a try.

[Guide] XT1575 Update To NPH25.200-22 Nougat After Modifying Your System & Re-Root

[Guide] XT1575 Update To NPH25.200-22 Nougat After Modifying Your System & Re-Root
THIS GUIDE IS NOW DEPRECATED. THERE IS NO NEED ANYMORE TO GO THROUGH THE UPDATING PROCESS AS THERE IS A FULL NOUGAT FACTORY IMAGE AVAILABLE (Build NPH25.200-22). FIRMWARE AVAILABLE HERE: https://forum.xda-developers.com/moto-x-style/general/xt1575-moto-x-pure-edition-factory-t3704142 BE SURE TO THANK @acejavelin FOR TRACKING DOWN THE FIRMWARE PACKAGE FOR US.
Notes:
-YOU ATTEMPT THIS AT YOUR OWN RISK IF YOU FLASHED ANY FIRMWARE PREVIOUSLY NOT FOR THE XT1575 US VERSION
-This guide will have 2 parts. 1 for those that kept their systems read only/systemless, and 1 for those that did not.
-Whether you live booted TWRP or Installed TWRP, if you chose to allow system modifications your OTA will likely fail (you'll need part 2).
-Restoring a TWRP backup will not work and will cause an OTA to fail due to having to allow system write access in TWRP - You Need Part 2.
-This guide assumes you have basic ADB knowledge and already know what fastboot is and how it works.
-Thanks to @gokart2 for the OTA and @acejavelin for the return to stock guides
Part 1: Those That Tweaked Systemlessly Currently On 24.49-18-16 (Will only work if you kept TWRP read only/used systemless root):
1: Disable & Remove systemless Xposed within Magisk Manager and all other Magisk modules. Reboot and wait for Art cache to rebuild.
2: Remove any adblock hosts within your adblock app if installed, or any other root level system altering apps like Greenify (don't worry, you'll get them back).
3: Remove Magisk by booting into TWRP and flashing the current Magisk Removal zip. Reboot.
4: For systemless SuperSu you need to consult their thread as I do not use it. (I'll update this if someone knows the correct process).
5: ADB reboot bootloader and fastboot flash the stock recovery. Latest MM recovery links at the bottom of this post. (rename file to recovery.img).
6: Move the OTA Blur_Version.24.231.16.clark_retus.retus.en.US.zip to the root of your internal sd card (NOT in a folder). File links at the bottom of the post. Thanks @gokart2
7: ADB reboot recovery, when "no command" is listed, hold power + tap volume up then release to access recovery options. Choose "apply update from phone storage". Choose the file and wait for the flash. It's a large update so be patient (about 10-20min). Choose reboot manually in recovery after flash succeeds. Enjoy Nougat!
8: For root you can go ahead and flash TWRP again or live boot TWRP (fastboot boot twrp.img) and then flash Magisk 14.0 from TWRP. Works perfectly.
Part 2: Those That Have Done Everything - TWRP Write Access, Custom Roms, On Older Firmware, Etc (XT1572 Build Flashers Do This At Their Own Risk):
1: Flash the latest full factory image available (24.49-18-8) available here: https://forum.xda-developers.com/mo...de-return-to-stock-relock-bootloader-t3489110. Thank @acejavelin for the thread while your at it. Follow the directions in that guide, it's well detailed and accurate - however read my notes just below first:
NOTES:
-Omit the "fastboot oem lock begin" & "fastboot oem lock" commands to remain bootloader unlocked.
-Omit the "fastboot erase userdata" command if you want to dirty flash and keep all of your data. I recommend clean, you can always root & restore each apps data with Titanium after the Playstore installs everything.
-The "fastboot oem fb_mode_set" instead of "fastboot oem lock begin" & "fastboot oem fb_mode_clear" instead of "fastboot oem lock" I've found to be unnecessary if staying unlocked. Your choice.
-The "fastboot flash partition gpt.bin" & "fastboot flash bootloader bootloader.img" commands will likely fail due to version mismatches. This is ok.
-The "fastboot flash modem NON-HLOS.bin" tends to fail too. For this, just run the command again until it succeeds.
2: After flashing 24.49-18-8 take the OTA to 24.49-18-16. Reboot. OTA zip provided below if you prefer to sideload.
3: Either install the 7.0 OTA the normal way via the update center or just side load it using the directions above. I recommend side loading due to the file size being very close to 1GB.
4: For root you can go ahead and flash TWRP again or live boot TWRP (fastboot boot twrp.img) and then flash Magisk 14.0 from TWRP. Works perfectly!

Alrighty. I got back to stock 6.0 with the 18-16 update. I couldn't get the OTA via the system update, so I tried doing it via ADB. That threw up a "status 7 error". I then copied the file to my internal storage and selected update via SD Card in recovery. It hung on "Patching System Files" for a while, but in the end it moved on and worked fine. Thanks for the awesome guide!

Thread updated with downloads for the 24.49-18-8 OTA to 24.49-18-16 zip.
I exctracted the 7.0 Stock recovery to replace if you decide to flash TWRP and want to go back to the stock recovery for future updates (HAHAHA yeah right!). Download link in OP. The 7.0 Recovery is different than the MM recovery. They are not interchangeable. Don't flash the 7.0 recovery on MM.

Question... can those of us who are rooted, custom roms, with TWRP, not just flash a stock unrooted TWRP backup from here: https://forum.xda-developers.com/moto-x-style/development/pure-firmware-tuff-wip-t3224833
Then, flash the stock recovery like it says... and take the update? Isn't that easier than this method?

It probably won't work. Once TWRP is given write access to your system (which is required to flash a full rom or restore a backup) any OTA's will fail. Plus any modem/bluetooth mismatches will cause a failure too. Fastboot flashing a stock image is really very easy & pretty much a guarantee that everything will work properly. However, if your able to get it to work, please let us know...though I don't think it will.

Once I do this, I can just reinstall TWRP and Magisk, backup the stock 7.0 and if I ever decided, just flash a custom rom later on?

hey thanks for the help on this one. I was so worried because I got stuck on th May security update OTA-wise.
question: I messed with the LatAm version of Nougat, so when I tried to re-lock the bootloader, it game the preflash error.
After this proper update flash, is there a way to run the bootloader CMD to just re-lock the bootloader?

Here's the recovery before the 7.0 one, just incase.. Was bored. Ok, I won't lie....didn't see u posted the 7.0 recovery....lol.:good::highfive:

Yup. TWRP flashes and works, magisk v14 works, and so far systemless xposed api24 is working.

What is everyone's fascination with relocking the bootloader? You do not need to relock your bootloader. You cannot relock the bootloader unless all your system partitions match. Use my part 2 section. Read the notes, skip the bootloader lock commands. Leave your bootloader unlocked, get up and running on nougat, then you can issue the lock commands if you really want a locked bootloader.

How exactly do you flash the 24.49-18-16 OTA? I'm stuck at this part
EDIT nevermind didn't read lol

Copy the file to the root of your internal storage. Reboot into recovery. Hold power = volume up & release to access menu options. Choose apply update from storage. Select the OTA.zip package and let it install. (Directions are clearly written in OP.)

Does it matter which version you're on? I'm currently on MPSH24.49-18-4 with the May 2016 security update.

Part 1 implies that you are on MPSH24.49-18-16 (dec), for part 2 - no it doesn't matter. Go ahead and start with the full firmware available MPSH24.49-18-8 and follow the steps from there.

Ok. Was going to have to follow option two anyway because of how I rooted...
Now I also take it that flashing Magisk is recommended, but optional?

Root is completely up to you. It's noted so users know that TWRP/Root are working. My logic with any XDA thread is that your bootloader is unlocked and you want root, but that's me...

I am running Dirty Unicorns right now and when i looked up what I'm on in fastboot, it showed MPSH24.49-18-16. Would I just follow part 2 and use MPSH24.49-18-8 or something? I thought I had to use at least the version I'm on or newer.

Your issue is that TWRP has modified your
System, any restoring of the stock rom will fail to update. So yes, you'll need to go through part 2 and downgrade and work your way back up.

I downloaded the zip (it took a while).
Restored to stock like 3 different ways but still hit a road block. I went the adb sideload route but got status error 7 because my build fingerprint wasn't correct. I tried searching for the right build I need, but I'm not an expert and couldn't find the right set of files that I was sure I knew how to restore. I ended up restoring my AICP backup.
If somebody could PM me and give me a hand (messaging through Hangouts or something) that would be AWESOME!
I'm planning trying to snag an XL 2 pre-order next week, but until then the less headache the better! Plus stock Nougat looks better on a Swappa listing

Trying to sideload via recovery 24.49-18-16 but I keep getting "("unexpected contents:EMMC:/dev/block/bootdevice/by-name/boot...". I've also tried installing from the phone but the same error appears in recovery. Any ideas?

Trying to Restore Phone to Stock (and a few other questions)

Hello!
I want to make my phone completely stock again. (Or as close as possible if completely stock isn't possible)
I unlocked, installed TWRP, and then rooted my phone yesterday (thanks to shashank1320's guide which made it very simple), but quickly found out that safetynet will prevent me from downloading and playing certain games on the Google Play Store.
After poking around online, it seems that even switching over to Magisk instead of using SuperSU will leave intermittent gaps in time where the app will be inaccessible due to the new workaround eventually being blocked.
So I want to go back. But like a derp, I forgot to create a backup beforehand.
So far I've unrooted through the SuperSU app itself, and flashed the BOOT.img and RECOVERY.img from Dazed No More's links in the Honor 6x Repository here.
After this is where I'm not sure what to do.
I think I need to find a factory system image to flash (and the vendor.img)?
I've seen a few threads saying that putting the UPDATE.APP in a dload folder into the phone and have the phone run the update worked (This did not work for me, although I'm not sure I have the right files; I downloaded it through a tech guide site here). I extracted the system.img and vendor.img from the update.app off that website using the Huawei Update Extractor, but I am afraid of flashing them in case they are the incorrect ones. But what if they are correct? Would I be able to recover if they are not?
Also, should I download and use unSU?
I know there is this guide on the front page right now. I've downloaded the Huawei Firmware Finder, but I... don't know how to use it. I narrow it down to the model number and that is where I get stuck. How... do I use it?
Some other basic questions I have in addition to this are:
Would I just have to flash the system.img and vendor.img through adb and then it will be stock again?
Would there still be leftover SuperSU files in my phone? I want to remove every trace of it. Would flashing be enough?
Am I even on the right track? And if not, where should I go from here?
Is the term "ROM" here firmware? Are the two terms interchangeable?
Ultimately, I would want to flash stock and then lock the bootloader again.
Thank you very much in advance. I appreciate it.
Edit: Wow I forgot to put any information, sorry about that.
Honor 6x
Model Number: BLN-L24
Build Number: BLN-L24C567B360
EMUI version: 5.0
Android version: 7.0

If you have unrooted, foashed stock boot and stock recovery rhen you are stock completely. For safer side, you can just dload the current firmware whch will lock your bootloader also and remove those device unlocked and cant be trusted message on boot.

Thank you! Currently it's still tripping safetynet, but that may just be due to the phone still being unlocked.
Would it be fine to just lock the bootloader through adb now?
And are all traces of SuperSU gone like this?

Nope. Locking the bootloader will just do it and reset but wont change the boot.img which root modified.
You need to unroot, flash stock recovery and stock boot.img to get rid of it.

Okay, since those have been flashed with stock, that means I'm set to re-lock the phone! Will get around to it sometime tomorrow c:

[Q]How to change root from phh.superuser to Magisk and upgrade firmware?

Hi Guys, I've been an active user of XDA in the past but didn't have time to follow in the last couple of years so my memory about flashing and tinkering is quite blank.
Here is my situation:
Mate 9 MHA-L29C636B158 (very old ROM)
Bootloader unlocked with paid code from dc-unlocker
Rooted with PHH's Superuser (the only root that was available for our device back in March 2017)
EMUI 5.0 and Android 7.0 (that was obvious from my Build number but I just wanted to state it again)
TWRP 3.0.2-2 is installed with system kept read-only. Internal SD seems to be encrypted
I never took any OTAs as I was afraid that they would break something
In the last month's many of my banking or financial apps have stopped working because I'm rooted so I read that Magisk would be able to circumvent this safetynet thing and would allow me to continue using these apps. Google Pay would be a nice addition also.
At this point I would like to upgrade my firmware and get rid of PHH's Superuser switching to Magisk instead
Could someone please write a detailed guide how to do that? It might be interesting for other users also that are in my same situation. I'm willing to donate a few bucks for a complete and foolproof guide.
Thanks a lot

Do you still have the unlock code? You'll want it, as the update from EMUI 5 to EMUI 8, on every device I've got, has relocked the bootloader.
With that said:
If you want to keep your data, make a backup using Hisuite.
Download the FullOTA firmware for your current version. Extract system, boot, recovery, recovery2 (as you're on EMUI 5) and flash them either in TWRP or fastboot; that should eliminate PHH SU and TWRP, and ultimately leave the system in a clean state.
If you modified other partitions on the device using TWRP or su in general, it wouldn't be a bad idea to use a nocheck recovery or HuRupdater to flash the entire system, to leave everything in a pristine state, since there are partitions you can't flash with fastboot, even with an unlocked bootloader. The instructions for HuR can be found elsewhere on XDA, as can details about nocheck recoveries, though the latter I'd be careful with - using HWOTA7 on Oreo, for example, WILL cause a brick. You've been warned.
Start the update process - you've already been approved for OTAs and they've been offered, so they should happen automatically. When Oreo is installed, it'll automatically relock your bootloader; you can continue updating here, though if you've got a particular target you want to go to, you might want to unlock and use HuR again to flash that specific one now that you're on Oreo. (The latest firmwares can't be rolled back to Nougat.) If you have no intention of going back to Nougat, you have your unlock code, and you aren't planning to do any other modifications like rebranding, then update away, though you may want to hold off of the Pie update if offered. (Shouldn't be, yet, but it could have been approved for your device already; it changes the boot partitions yet again.)
Now that you're on Oreo and presumably unlocked again, make sure you've got the FullOTA image downloaded for that firmware to your PC. (Always a good idea, anyway.)
Magisk can be installed by:
1) Flashing TWRP with fastboot, then flashing a suitable Magisk zip
2) Using Magisk Manager to patch a boot image and flashing that.
For TWRP:
Get a copy of TWRP from the forum here. When I use one, it's the 3.2.1-0 from @Pretoriano80, you'll find it in the development section. Any 3.2.x for Oreo should work though - a Nougat TWRP will not work.
Flash TWRP to recovery_ramdisk in fastboot. Boot to TWRP, flash Magisk.
For Magisk Manager:
Extract "ramdisk" from your FullOTA firmware. Place it in internal storage on your device. Use Magisk Manager to patch the image (install / patch boot image). Transfer the patched_boot.img created by Magisk back to your PC and flash that to the "ramdisk" partition in fastboot.

Just stumbled over your reply, didn't get an email notification from XDA. Thank you so much. Let's see if I can follow your instructions.

Do you still have the unlock code? You'll want it, as the update from EMUI 5 to EMUI 8, on every device I've got, has relocked the bootloader.

Download the FullOTA firmware for your current version. Extract system, boot, recovery, recovery2 (as you're on EMUI 5) and flash them either in TWRP or fastboot; that should eliminate PHH SU and TWRP, and ultimately leave the system in a clean state.

I downloaded the FullOTA with the FirmwareFinder app on my phone and transferred it to my laptop. Extracted the update.app with WinRAR and extracted system, boot, recovery and recovery2 using the Huawei Update Extractor 0.9.9.3.
Just to make no mistake, could you please confirm the order of flashing these 4 files? And maybe the correct command to use in fastboot?

If you modified other partitions on the device using TWRP or su in general, it wouldn't be a bad idea to use a nocheck recovery or HuRupdater to flash the entire system, to leave everything in a pristine state, since there are partitions you can't flash with fastboot, even with an unlocked bootloader. The instructions for HuR can be found elsewhere on XDA, as can details about nocheck recoveries, though the latter I'd be careful with - using HWOTA7 on Oreo, for example, WILL cause a brick. You've been warned.

I don't think that I modified any other partitions, at least not willingly. I even left the system in read-only state. Don't know if phh.su did something by itself?

Start the update process - you've already been approved for OTAs and they've been offered, so they should happen automatically. When Oreo is installed, it'll automatically relock your bootloader; you can continue updating here, though if you've got a particular target you want to go to, you might want to unlock and use HuR again to flash that specific one now that you're on Oreo. (The latest firmwares can't be rolled back to Nougat.) If you have no intention of going back to Nougat, you have your unlock code, and you aren't planning to do any other modifications like rebranding, then update away, though you may want to hold off of the Pie update if offered. (Shouldn't be, yet, but it could have been approved for your device already; it changes the boot partitions yet again.)
Now that you're on Oreo and presumably unlocked again, make sure you've got the FullOTA image downloaded for that firmware to your PC. (Always a good idea, anyway.)
Magisk can be installed by:
1) Flashing TWRP with fastboot, then flashing a suitable Magisk zip
2) Using Magisk Manager to patch a boot image and flashing that.

Will continue to do the above after your kind confirmation of my last questions. Thanks again

The order shouldn't be particularly relevant, just that it's safest to reflash all of them:
- boot because phhsu may have modified the boot image to add su to it
- recovery and recovery2 because you loaded TWRP. recovery2 is specified because it's used to be recommended to flash to erecovery as well as normal recovery.
- system because I'm pretty sure that's the biggest thing modified Hy phhsu, and any other system changes you may have made.
Theoretically, other modified partitions won't matter since the upgrade to 8.0 replaces most (all, I think) of them anyway, but if you have to go through update steps through EMUI 5 first before it'll give you 8, then it's safest that they aren't modified. I mentioned other partitions because, with root & TWRP, you technically could have modified any and all of them.

Flashing of 158 (original ROM version) went fine. Phone rebooted and titanium reported no root access, so it looks good.
After that I started the OTA update to 172 that waited already long time in my settings and it downloaded it. After downloading it gave me an error during the validation process of the file and asked to download it again.
Unfortunately now both the phone updater and the HiSuite app on my laptop say that 158 is the latest available firmware and no update is available.
I guess that I can download directly the newer firmware but I'm not exactly sure how to flash the whole package and what I should do with the other 2 files that come with it besides the update.zip

It might be tweaking out about the fact that you'd previously modified system.
I'd grab the last Nougat release (looks like 191; there are 2 of them, be sure it's not the rollback one you grab) and use hurupdater in TWRP to install it, then let the system try running OTA again.

I had to insert the SIM card of the country I bought my phone in to get the OTAs coming. Luckily I still had it with a few $ credit on it. It used just a few cents in data roaming for finding the new firmware, then I downloaded through wifi.
After 4 updates now I'm on 378 and no sign of Pie yet so this afternoon if I find some time I'll continue with rooting.

Easy way:
Unlock phone, if you haven't yet again.
Download and flash TWRP from here: https://forum.xda-developers.com/mate-9/development/recovery-twrp-3-2-1-0-t3783353 (has decryption support) (flash to recovery_ramdisk as Huawei decided to split recovery partition into different parts)
Boot to TWRP, input pin (if you set a pin, else it will decrypt automatically)
Download Magisk: https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445
Transfer Magisk to phone.
Flash Magisk zip in TWRP.
Reboot and you're done.
You might have to tinker around with Magisk Hide and hide apps if your banking apps still detect root.

As the Huawei Backup took over 4 hours to finish and i can't use Titanium, which is much faster, because I'm not rooted at the moment, I thought it's a good idea to first upgrade to Pie before unlocking my bootloader and losing all data. If I need to stay a few days without root it's ok.
Is there any way to get to Pie without being rooted? I tried the erecovery method on firmware finder. It says that my IMEI is now registered to download the update but when I enter erecovery it starts downloading the 378 oreo package.
I would like to avoid backing up and restoring twice this lengthy process, probably 16 hours all in all

The erecovery method won't work unless you can change the DNS settings on the network being used - it hijacks some of the requests to Huawei's servers to force the update. (And even then it's a bit finicky; I have yet to successfully use it, all things considered.)

Yesterday I finally received 9.0.1.159 with EMUI 9.0.1 by OTA. It installed fine and it's amazing how fast my phone became and how much screen on time I have now with my 2 year old device (8 full hours!). Good job Google and Huawei.
Being on Pie now I suppose that the instructions to root from you and ante0 are not valid anymore as they were meant for Oreo.
Could you please modify the instructions for Pie? And further, as I see that since yesterday in FirmwareFinder a new Pie update 9.0.1.178 popped up, could you please also add instructions how to take this OTA being rooted with Magisk once it arrives?
I've read a bit in the Magisk thread but I did not really understand the part of having to boot to recovery everytime I switch on the phone. Further they are talking there about EMUI 9 but I have already 9.0.1, is there maybe a difference I have to take care about?
Last but not least, I didn't forget my initial promise to donate a few bucks for the detailed instructions so please drop me your email in PM and I'll sent you a few through PayPal or in alternative, if you have some paid apps on the Playstore I could buy them so they might get more visibility.

The reason recovery boot is needed for Pie is because Huawei removed the ramdisk - in Pie, it's system as root with no way of forcing a ramdisk except by a recovery boot. So as a workaround, Magisk takes over recovery.
The installation instructions for it on Pie are pretty much the same as Oreo, except:
* Patch recovery_ramdisk, not ramdisk. Latest stable Magisk should work (18.1, iirc, has the patches to support recovery boot.)
* When booting, go to recovery. Magisk will start from there and take over the startup process.

Hmm, where do I find the TWRP for Pie in order to flash?
And most importantly how do I have to behave in case of new OTAs coming?

TWRP on this case, don't bother.
Extract your stock recovery from your firmware's update.app file, patch with Magisk Manager, and flash the patched image. When you want to flash an ota, put the stock recovery back.
