[Solution] Getting Android Pay working on Pure Nexus , Chroma, or OMNI

Special thanks to @funkyboy1281, @lentm, @macboy3000 for helping getting this work. As far as I can tell, this is the easiest and most straight forward instruction set for getting Android Pay to work on the latest version of Pure Nexus, Chroma, or OMNI Rom
Clean Flashing
Download the appropriate Rom.
Pure Nexus Discussion​Chroma Discussion​OMNI (no link available, sorry)​
Download Pure Nexus Dynamic Gapps 2-3-16 (Very important, you cannot use 15-3-16 or later). Yes, even if you use Chroma or OMNI, these Gapps should work for you. Link
Download the unSU script for completely unrooting before installing systemless root. Link
Download SuperSU 2.68 (or higher) Link || Discussion
Advance wipe in recovery all but internal storage
Install the ROM, gapps, and unSU
Optional: Install custom kernel
In TWRP, under advanced, go to terminal and type the following:
Code:
echo SYSTEMLESS=true>>/data/.supersu
echo BINDSYSTEMXBIN=false>>/data/.supersu
Note: You may also do this using ADB in recovery (adb shell, and then enter the same commands. This is much easier in my opinion, and is the method I used.
Flash 2.68 beta in TWRP
Fully reboot, go through initial device setup
Verify in SuperSU that you cannot install SU to the system. This will verify that we are using the systemless root option
Download SafetyNet Helper and make sure it passes
Install Android Pay and profit!
Dirty Flashing
Verify that SafetyNet still passes in Android.
Verify in Android that /data/.supersu is still present and contains the appropriate options (see clean flashing). You may also verify in recovery by going to terminal commands and entering in:
Code:
cat /data/.supersu
Install the updated ROM (do not reinstall gapps unless your ROM builder specifically tells you to do so. Pure nexus does not require a reflash)
Optional: Install unSU. This was not necessary on PureNexus, but I cannot be sure for other roms. It shouldn't hurt anything to flash.
Optional: Install custom kernel
Install SuperSu 2.68 (or higher)
Check SafetyNet Helper and make sure it still passes
FAQ
Q. Can I still install and use AdAway?
A. Yes. You must first install something in recovery before installing AdAway. See the discussion Thread. You should be installing v3.1 of the app after you install the recovery zip.
Q. Can I still use V4A?
A. Yes. I do not use this however, but it has been reported that nothing special needs to be done.
Q. Can I change the screen density?
A. We have not found a way to do this without tripping Safety Net

@skaforey thanks for this thread! Might want to note in the OP that Wiping Data erases the internal storage. Some people may not know that.

Noted, thank you! Still hoping some of the lucky folks that have it working can help us out here.

Has anyone found a way to adjust the screen density while keeping Android Pay functional?

You (should) be able to change the density through adb using
Code:
adb shell wm density DPI
with dpi being what you want, or if you have root you can do that from a terminal emulator, just remove the adb shell part.

I tried the 2nd method without formating data in different combos to no avail, still hesitant to wipe my internal sdcard, it shouldn't be that hard man, will follow this thread
anyone know other aosp ROMs that have AP working outside of pure nexus?
Sent from my Nexus 6 using Tapatalk

Following the steps in the top most instructions in the OP...
1) Pure Nexus 3/8 does not have root out of the box, so the Unroot step was not needed.
2) TWRP did not show any files/folders in the /su directory, so the Terminal command didn't work. I booted up the device and did it through the Terminal there instead and then rebooted.
After that, loaded up Android Pay and it says "Android Pay can't be used".
Running SafetyNet reports....
SafteyNet request: success
Response validation: success
CTS profile match: false

Tried different methods, not working for me.
1. Download Pure Nexus 1/03/16 or newer (Layers), the latest PN GApps, UnSU, the latest SuperSU.
2. Backup any important data.
3. Boot into TWRP and wipe everything including internal storage
4. Format data.
5. reboot TWRP with USB-OTG that has fines necessary.
6. Flash Pure Nexus.
7. Flash GApps.
8. Flash UnSU.
9. In terminal I saw I still had a folder /supersu so I deleted that.
reboot. Setup phone with google account. Did not have it restore apps, but did have it restore basic setup from google.
Install Safetynet helper
Still fail CTS Profile Match
Don't know what the people are doing different, but not working for me.
Are you using the PN-Gapps or others?
The updated-unsu is what date?
Thanks!

The only way I have gotten AP to work is from a stock image based ROM. It doesn't seem to work with AOSP ROMs like Pure Nexus.
For example, I am currently running Tupac's debloated stock ROM with Cataclysm MOD, Viper4Android and AdAway ad blocking. Android Pay works fine, as long as you follow the SU steps listed in the OP of this thread.

What I did to get AP to work was removing these lines from updater-script located in META-INF > com > google > android
Code:
ui_print("Flashing SuperSU..");
package_extract_dir("supersu", "/tmp/supersu");
run_program("/sbin/busybox", "unzip", "/tmp/supersu/supersu.zip", "META-INF/com/google/android/*", "-d", "/tmp/supersu");
run_program("/sbin/busybox", "sh", "/tmp/supersu/META-INF/com/google/android/update-binary", "dummy", "1", "/tmp/supersu/supersu.zip");
ui_print(" ");
and removed the supersu folder inside the zip file. I then installed my custom kernel and systemless supersu. After that, I set the permissions for bin folder inside su to 751 using a root explorer and deleted xbin_bind.

@macboy3000 what kernel and what version of SuperSU did you use, ? I tried your method, ROM booted fine but safetynet test failed...
this is how I did it
unzip ROM
edit code out
delete supersu folder
zip ROM
advance wipe everything but internal
flash ROM
flash pn gapps
flash elemental kernel
flash supersu
boot into android, delete xbin_bind
reboot system
permissions on bin folder were already 751, so didn't need to change

Well I tried this and still no luck
I even tried flashing the modified ROM, gapps, and never flashing SuperSU at all (so my rom wasn't rooted at all), and SafetyNet still gives me a red screen. I really wish I knew what was triggering this for some and how others can make it work.

I tried again using 2.57 SuperSU and Elemental X and still fails. Would someone that got it working be able to post a more detailed log of exactly what steps you're using and exactly what files you're flashing.

[ROOT][6.0][XT1097] Systemless root for Moto X 2014

Hello, everyone!
TL;DR: You're about to perform a systemless root installation on your phone so make sure you have uninstalled Xposed Framework, uninstalled root, the device's bootloader is unlocked and your phone's boot image is in its untouched stock state. Then boot into TWRP and install SuperSU-v.279-SR3 or newer.
UPDATE 2017-01-19:
- Provided missing bootloader information regarding root. Thanks, @Charlita for the heads-up!
- Moved TL;DR section to the top.
UPDATE 2017-01-15:
- SuperSU-v.279-SR3 learned how to use systemless mode as default flashing method for Motos. This is great news as the installation process now is just a matter of flashing the SuperSU installer. The segmentation fault had been fixed on SR2 and this version also includes that fix.
- Included a TL;DR section.
UPDATE 2016-12-25:
- SuperSU-v.279-SR1 contains a regression bug regarding the "segmentation fault". Skip this version for now. I've already contacted Chainfire.
- suhide: as the Chainfire himself stated, the tool is a losing game so I'm not putting any further effort here.
UPDATE 2016-11-03:
- As of SuperSU-v2.78-SR3 boot image patching works out-of-the-box. Just install it and you're done!
- TWRP version 3.x works as expected.
- Unfortunately, SafetyNet checking fails as Google constantly updates the server-side code.
- WIP: Check if Chainfire's suhide are able to help here.
UPDATE 2016-08-08:
- Added a backup reminder.
- Added flashable zip systemless_root_enabler_by_glauberlima.zip.
After a few days playing with it, I finally managed to perform a systemless root install for our beloved Moto X 2014
Benefits:
- Install OTA updates when they arrive;
- SafetyNet checking will pass so Android Pay can be used (not available in Brazil yet).
Requirements (links below) :
- Android 6 Marshmallow
- Bootloader must be unlocked otherwise you won't be able to root your phone;
- Boot partition must be in its original untouched stock state otherwise, SuperSU installer won't be able to patch it;
- System partition must be untouched as well but a simple uninstall of applications that have changed it should be enough. This step is not mandatory but if your system partition remains changed SafetyNet checking will fail;
- Your device must be unrooted. SuperSU has the option "Completly remove root". Use it;
- If you have Xposed Framework installed, uninstall it;
- You'll need ADB and Fastboot in order to flash stock boot.img if applicable;
- TWRP. Version 3.0.2-2 works just fine. If you prefer 2x series, I highly recommend version 2.8.7.1;
- SuperSU-v2.79-SR3 zip installer (or a newer version). DO NOT TRY AN OLDER VERSION. WILL NOT WORK;
Install guide:
- Make a Nandroid backup first using TWRP;
- Uninstall Xposed Framework if applicable;
- Uninstall SuperSU;
- Connect your device to your computer via USB;
- Reboot into bootloader:
Code:
adb reboot-bootloader
- Restore stock boot partition (you can skip this step if you already been on stock boot):
Code:
fastboot flash boot xt1097_boot_stock_with_may_2016_update.img
VERY IMPORTANT: The binary file boot xt1097_boot_stock_with_may_2016_update.img is device dependent. I have extracted stock boot.img from victara May 2016 update full ROM package and put it here. If you are trying on the other variants, make sure you will use the right image.
- Reboot into Recovery (TWRP);
- Flash the attached zip file systemless_root_enabler_by_glauberlima.zip. This will set both variables SYSTEMLESS=true and BINDSYSTEMXBIN=false. Without these variables set, SuperSU will fail to systemless root the device. Feel free if you want to manually enter the commands in the Command Prompt:
Code:
adb shell "echo SYSTEMLESS=true>/data/.supersu"
adb shell "echo BINDSYSTEMXBIN=false>>/data/.supersu"
- Install SuperSU and reboot system. If the first boot fails, just wait - the second will work I promise you!
- As soon as Android UI shows up you should be systemless rooted;
- Confirm SuperSU is installed by recognizing the green icon on your app drawer;
- Open up any root app you have. The world-famous Superuser permission request dialog should pop-up;
- Install SafetyNet Helper, in order to attest your Android, is passing Google's SafetyNet checking: https://play.google.com/store/apps/details?id=com.scottyab.safetynet.sample
Now you should be good. Congrats!
Go ahead and get some systemless apps:
- Systemless Xposed Framework
- Systemless Adaway
This procedure should work for the other variants too - all you need is the original boot.img
If you need any help feel free to ask.
Attached you can find the screenshots taken from my XT1097 after the procedure

Since your device already has the untouched stock boot you don't need to flash anything.

I seem to be having trouble installing the "Systemless Xposed". It errors out with - ! Failed: Unable to extract zip file!
I have verified "systemless root - ver 2.76" and tried re-downloading the zip. Any thoughts?

Could you provide your recovery.log from TWRP so we can see the detailed logging information?
You can pull it from your device by running the following command in command prompt:
Code:
adb shell cat /tmp/recovery.log | clip
This will copy recovery.log contents to the clipboard. Paste it into notepad then save and attach here.

This is pretty neat. Given what I read as the requirements am I correct this only works with stock ROM? (and test will only pass on stock).

Hi @vpxf
The unmodified boot.img is a requirement for SuperSU as it tries to patch the boot image on-the-fly during the install process (by the time you flash it using TWRP). If the image is not in its original state, SuperSU will fail to install in systemless mode.
Regarding your question about custom ROMs compatibility I don't know if the SafetyNet checking will pass/fail. That's a good test to perform.

I've attached the log. I did notice "unzip: zip flags 1 and 8 are not supported".
NOTE: I was able to flash the 85.7 version found in the second post of the "Systemless Xposed" thread. The newest 86.2 is the one giving me troubles.

As glauberlima found out in the other thread, you need to re-zip the xposed installer with 7-zip (that's what i used at least) and the install will work.

Regarding your device being systemless rooted check with SafetyNet Helper Sample app. If everything turns green you are good

** Duplicated **

Thanks for the tutorial.
The first boot fails, ok ; but how long is the second boot ?
I wait a long time (around 15 minutes) blocked at the first screent (static moto logo) and I stop it, reboot and reinstall my backup. I panic a little

15 minutes... That's definitely too much.
I'm about to update this guide with my new findings so If you don't mind I'd like to suggest you this:
Repeat the steps but this time skip the update to latest version. After the reboot access SuperSU. It should display a message regarding your su needs update. Accept it.
Make sure your nandroid backup is up to date.

Same thing, but it's possible that my boot image is not up to date and I have no other boot backup to test.
I have only a complete backup (boot + system without root), perahps I'll try later with complete restore ...
Thanks

Something went wrong, the root works fine, but when I run the SafetyNet test, I got "CTS profile match: false", I just want to keep the OTA upgrades working, if I did something wrong, is there any way to unroot and do the systemless root again?? Thankss

Hi! Hey, I followed the steps and my MotoX got stuck when rebooting after flashing. I'm trying to enter fastboot with power+Volume down but no luck so far, any idea? I hope you can help me!

[Magisk/Root/Xposed/Busybox]Huawei P9 Lite

-This methode is old but working with emui 4 Android MM (6). Not work with Android N (7).
-Xposed not work in systemless mode if your Android security patch is >= november 2016
-Try to search the last version of zip files and apk on google, the version on this tutorial is old.
Hi!
This tutorial will install Magisk, phh's superuser, xposed and busybox on your Huawei P9 lite device!
Tested on a VNS-L31C432B151 version but normally work on all VNS-L31 and VNS-L21.
Magisk will allow you to "hide" the root... not realy just hide because Magisk and phh's superuser systemless edition create the root outside the system folder!
Magisk feature for common user:
-"hide" root (PokémonGo, Androidpay, banking app, ... all work!) work with
-Magisk not only allow you to replace existing file and directories, but also support adding new files and directories into system!
-Update OTA work! (not tested by me)
For more detail visite this post: http://forum.xda-developers.com/android/software/mod-magisk-v1-universal-systemless-t3432382
Phh's superuser work at 100% on this device
After a lot of Xposed version tested I can say that Xposed systemless edition is by far the best for P9 lite!
DONT install busybox on system folder!
Ok let's go:
1 Update your system on last emui version and swipe data/factory reset to get a clean and untouched device!
2 Unlock your bootloader (see multiple method on this forum)
3 Install TWRP 3.0.2.0 (see multiple method on this forum)
4 Download this files: Magisk V6.zip / phh's superuser 17.zip / xposed-v86.5-sdk23-topjohnwu.zip / Magisk Manager.apk / XposedInstaller_by_dvdandroid.apk. Put all this files on your externalSD.
5 Go to TWRP recovery and flash in order [Magiskv6.zip > phh's_superuser.zip > Xposed-v.86.5.zip] also reboot your device.
6 When you are on the homescreen go reboot again.
7 Install Magisk Manager.apk and XposedInstaller.apk, then go to the playstore download and install Phh's SuperUser app AND Busybox meefik. Reboot after this step.
8 Open your setting app and allow permission SD card to Busybox.
9 Open Busybox >> settings. Remplace the path file /system/xbin/ with /data/busybox/ and check "Remplace Applets". Also go Menu Zip Archive and download this zip.
10 Go on TWRP recovery and flash the busybox zip file.
10 please perform 3 or 4 reboot
DONE!
So, please try to open yours setting app. if it appears you have done! If not, please try again this method
Now, go Magisk Manager (app) and switch root togle off, launch your protected against root app and normally work!
(Dont need reboot between switch root off/on!)(Selinux switch work, but not persist a boot)
Have fun!

Well done. Works perfect.

Hey, man I've tested it on my Huawei P9-LITE B370 and it all works perfectly. To flash Magisk, you need this custom recovery (https://forum.xda-developers.com/huawei-p9lite/development/twrp-t3588356)

this really helped me thanks

Helped me alot. Still, post is a bit old, so what I did on b380 version:
FLASH RECOVERY twrp-3.1.1-0-venus.img
FLASH KERNEL Elite+Kernel+for+P9+Lite+CxxB3xx+v10.1.zip
ROOT with Magisk-v13.0(96f8efc).zip
INSTALL busybox archive via recovery to /sbin (for me it installed on /system/xbin, still ok.)
REBOOT after each step
Finally works ! :good:

is this Magisk work on Huawei P9?

I have Emui 5.0 and Android 7.0. I flashed everything except xposed but I still can't use Pokémon Go or Snapchat. Is it beacause i can't flash xposed? And when yes, how can I fix it?

#### DESCRIPTION
Some kernels from devices with F2FS-formatted data partition (i.e., Motorola) have a bug which prevents loopback devices (.img files) from being mounted read-write. This limits systemless modifications that can otherwise be achieved with Magisk.
This module works by moving magisk.img to the cache partition (EXT[2-4]-formatted) and linking it to its actual location (i.e., /data/adb/magisk.img). The other half of the process consists on automatically recreating magisk_merge.img shortly after boot and handling it the same way as magisk.img.
With this workaround, a patched kernel is dispensable.
Cache partition's size is essentially the only limiting factor -- and that's pretty much self-explanatory.
/cache/magisk_.img is automatically backed up to/data/adb on boot (only if modified) & restored on install. Thus, whenever cache is wiped, magisk_.img and its respective symlink can easily be restored by simply reinstalling the module.
---
#### PRE-REQUISITES
- Magisk v15+
- F2FS-formatted data partition
- EXT[2-4]-formatted cache partition
---
#### SETUP STEPS
Fist time
- Install from custom recovery as a regular flashable zip.
Upgrades
- Install from Magisk Manager or custom recovery.
- Reinstall after cache wipes to restore magisk.img backup.
---
#### NOTES/TIPS
Always install large modules from custom recovery only. In fact, I recommend installing every module from recovery if your device's cache partition has a very small size (i.e., only a few Megabytes).
To revert changes, uninstall the module, boot into custom recovery and delete </data/adb/magisk.img> & <magisk.img.bkp>. Lastly (while still in custom recovery), move </cache/magisk_.img> to </data/adb/magisk.img>.
Updates and reinstalls can be carried out from Magisk Manager as well.

Works with stock roms as well ?

My cat lost two and half lives because of this thread. Sadly, the disclaimer is in order, so I can't sue.

Is this for Nougat or Marshmallow?

does this work on nougat update or only on MM?

Can someone please confirm if it will work on retin channel with dual sim... I am running stock nougat... Will it work or does it only work on MM rom...

Anybody know how to fix notifications without breaking safety net?

It should work on both Marshmallow and Nougat, as long as you pick the appropriate kernel for your system version (6 or 7). @mhp1995, I don't think the software channel matters. It should work across all (retus, retin , reteu, etc.).

No idea at this point, man. I've never had to fix mine. Perhaps only some people have it...?
@erwin, I chose not to touch the stock recovery to keep OTA installations straightforward. Easy for everyone.

one question... if i wanted to install viper4android and xposed framework, should i download it from the magisk download tab or shud i flash them manually via TWRP? thanks

There are specific versions of these modified for systemless root. DO NOT install the standard versions. You should follow the instructions given in Magisk Manager app to download and install.

Oh, yes the availability... I forgot to mention that. Hopefully a proper Xposed version will be available for nougat very soon. When that happens, I'll update the thread.
About adding the tutorial to your thread... sure, go ahead.

I honestly declare I didn't read whole thread - is this method work for stock Nougat rom - I need root for Titanium Backup only for now , since facebook messenger goes crazy on my new phone MZP :-/ . Or maybe there is a way to restore old conversations ,not restored automatically in Facebook Messenger - anybody knows how to do it ? . On every phone I had I used root for two things mainly - Titanium Backup and to block adds - dns66 do block adds very well without root but , Titanium Backup has no alternative for me .

Just for the records: Magisk 12 release works fine.
@sebx_g1 incredible 2 pages! That are more than 10 postings! Sure nobody can read so much. And nearly all ask or answer your question, but it is just too much ...

What is expected to be done for next OTA to work? Just restore Nandroid backup of boot partition and everything should be ready for patchlevel newer than January 2017, right? And afterwards f2fs fixed kernel and Magisk again for having root again of course.
(twrp not flashed, no logo modified, system should be untouched)

Xposed does not work on Nougat by now. Magisk does. The 2 negative votes you counted referred to Xposed

Anyone have an adblock that works with systemless and passes safetynet? Do we need to check the "enable systemless for adblocks" in Magisk settings?

DNS66 do the same what do adblock, you can use it without root. But yes, there is special version of adblock systemless.

[ROM]Multi-Rom Tripl3t B594 Odex

http://pecholite.blogspot.com.es/2017/03/multi-rom-tripl3t-b594-odex.html?m=1
MULTI-ROM TRIPL3T B594 ODEX
Multi-rom Tripl3t is the first rom for pecholite that adapts to all types of users and allows to start the smartphone with Emui 4.0, LineageOS 14.1 or AOSP 7.1.1 (Nougat).
I present my first custom rom based on fellow cerberus v2 + John Miller . The Lineage part is @XePeleato and the Aosp of @haky86.
Too much for you?
More novice users should not be scared because the installation and configuration is incremental and that is why I say that it fits any user profile.
User Profiles:
Depending on the concerns that are most suited to your profile you should take the installation to the point that best meets your needs.
As a user I want ...
1- I want a stock experience with some extras but without Root.
You must install the rom file by TWRP and dot. The rom is the same as the cerberus V2 but comes with no root.
It incorporates among others ..., gyroscope, call recording, multiwindow ...
REQUIRED REQUIREMENTS:
-Bootloader Unlocked.
-TWRP
- Android 6 - C432B594 Stock - Recommended.
2- I want you to have root access too.
After installing the rom you must enter the store and download the application magisk manager and ready. You already have root access and get the most out of the rom, but not only that, but root access can be hidden to play PoGo or use payment applications and pass the SafetyNet test.
3- I want to activate extra functions and transform and customize the rom butt.
Well what you have to do is install this file from TWRP point.
We will achieve the following:
- Activate Multiuser
- Enable Local Update
- You can choose whether to install the Huawei magnifier or not
- Busybox, Viper4Android and SLC disappear
- You can choose to install the busybox and the viper in a systemless way and in this way the SLC is no longer necessary
- Advanced Reset
- New lock screen 100% customizable.
- The screen automatically turns on and off when opening and closing the mobile phone case
- Incorporates system apps uninstaller
- Total Commander
- Greenify
- Etc...
4- I want to be able to choose which rom to start the smartphone.
For that it is necessary to have followed steps 1, 2 and 3 and it is necessary to configure magisk to have default access to all requests per adb and applications and install the multiboot option.
To install Dualboot you must go to the file EXTRAS.ZIP that you will find inside the system folder of the rom. Uncompress your content in the external memory and install the DualBoot app and keep the files in memory because we will need them for later.
Then we start the dualboot application to be granted superuser permissions automatically. Then with SimpleReboot we restart a recovery and make a backup of boot.img in case something goes wrong, since it will be the only thing we will need to repair a possible failure or error.
VERY IMPORTANT: We need to have 3Gb of available space in the External SD for each additional rom we want to install, that is, if we are going to install Lineage and Aosp we will need 6Gb of available space.
4.1- I want AOSP.
We must download these files and install them at the same time and in order from TWRP
- Rom
- Aniboot
- Gaaps
- Magisk
4.1- I want LineageOS.
We must download these files and install them at the same time and in order from TWRP
- Rom
- Aniboot
- Gaaps
- Magisk
4.3 I want the 3 Roms at a time.
Then follow steps 4.1 and 4.2
Restarting the system will take us directly to the last ROM installed. Once started and configured we installed the dualboot app that we had left on hand in the external SD. Repeat the operation on each of the additional roms installed. Once installed dualboot in all you can remove the app from the sd and of course all the corresponding installation files.
To change rom you have to enter the dualboot app and choose which one to start the system and restart.
MENTAL NOTE 01:
The 3 roms will have the same bugs as the originals. I am not yet qualified to fix them or even try, but I think that to be my first job is more than enough.
MENTAL NOTE 02:
The DualBoot application also installs an app called Leaks that controls possible bugs to send them to the original DualBoot developer.
I do not want to forget to give credits and thanks for:
@topjohnwu for creating magisk
@chenxiaolong for creating DualBoot and @BrainNotFound for portarlo
+ John Miller to create CerberusV2
@haky86 for creating Aosp and CWMR
@XePeleato for creating LineageOs and TWRP and Kernel
Greetings from Barcelona (Catalonia)

Why in the screenshots there is a ss with a lockscreen asking for a fingerprint to unlock? I know that no P8Lite has a fingerprint sensor

Try a factory reset with stock recovery and flash again.
It helps in most cases

It worked for me once but I think I reflashed something or so and then it didn't. After flashing it wait at least 1 hour before stopping the boot. After that, it doesn't seem to work.

It works. Flash Xposed and don't forget to wipe cache.
Phone will start in about 30 minutes.
It works. Use SDK 23 for this rom

No with the B596 ROM (i think its related to the new security patch)
With the B588 instead you have to disable xposed reboot the phone and safety net will be ok

I can confirm Xposed works. Not the Magisk one though.
Use the one from the mega root thread https://forum.xda-developers.com/p8lite/general/mega-thread-root-unbricking-updating-t3400994.
I also know the xposed torch works. Like to recommend xEmui module.
