Unable to Pass Safety Net?

I've been trying very hard to pass safety net on my axon 7, I first tried when I had LineageOS, Magisk and Xposed (not systemlessly installed) and a few other tweaks that appeared to modify the system partition, then after realising they may be affecting safety net I completely wiped my device (data,cache,system) to make sure I had a completely fresh start. Then proceeded to flash the MicroG version of LineageOS, and install Magisk and Xposed Systemlessly making sure nothing I did affected the system partition. So I thought I would be set, did safety net check andddd it failed. Then I did some searching and found safety net will check for bootloader unlocked status, so I found a kernel (HELLSGATE.V1) which tricks safety net (or is supposed to) into believing bootloader is still locked. And safety net still fails, this is really annoying I'm just wanting to use Android Pay yet I can't. Does anyone have any idea as to what would be tripping safety net in my case, or how they manage to pass on their device?

Xposed is causing safetynet to fail. No matter how Xposed is installed, it will always trigger safetynet. But with systemless xposed, you can disable xposed in the xposed installer app by toggling it at the top and rebooting

Still get 'invalid response' through magisk manager even after disabling xposed
This is why mine stayed stock......
Normally I would at least unlock, install TWRP and root to de-bloat, install V4A and maybe Xposed. Had to wean myself off those mods on this phone but used to it now. Life is much simpler
Nougat is pretty good. Be nice to see Oreo official soon.

Safetynet doesn't check the bootloader. Look I can even pass safetynet while dualbooting LOS. Just wipe system and install LOS, OpenGApps and Magisk, maybe some other mod like the AK4490 patch and Viper4ARISE. That definitely will pass safetynet.

Pass SafetyNet with Magisk

After a long time using SuperSU, I switched to Magisk yesterday, for it's modules and of course Magisk Hide. So, starting with a full stock B414 rom, I unlocked my BL, installed OldDroid's TWRP and flashed Magisk 16.0 .
Everything went fine, I'm able to give root access to my apps. What I'm trying to do now is passing SafetyNet check.
I downloaded SafetyNet "attest" from the store and ran a test -> Basic integrity : false and CTS profile match -> false :crying:
Reading various tutorials, I enabled magisk hide, selected a few google apps to hide (store, services framework) , enabled Host systemless and magisk Core (rebooted my phone between these changes), cleared Store data. Regardless of what I've done, I keep failing at SafetyNet check. Did I miss something basic ? Did someone manage to pass safetynet on a P9 Lite with Nougat ?

Hello,
i used it some times ago...
Try to enable usb-debugging together with magisk/hide,
then reboot and see what happen.. ( this is what i done )
All the best
Thanks for your answer ! However, it didn't changed anything, safetynet check failed. Interesting fact, after rebooting, both magisk hide and usb debugging are disabled... Is this normal ?
EDIT : It's more than that, usb debugging gets disabled as soon as I quit settings
managed to fix this using another xda thread, but safetynet keeps failing and magisk hide is always disabled on startup

Passing Safety Net

Hi All,
I have been running Lineage OS since it became available for OnePlus 5 with the Safety Net successfully being passed using Magisk and using firmware and modems from jamal2367.
That was up until Lineage required an updated firmware/modem to 5.1.4 and I found jamal2367 has stopped doing the firmware and modem for the OnePlus 5. I installed the firmware from shadowstep the new firmware provider and now I fail the safety net checks.
I have tired the following:
Flashing multiple weekly releases of Lineage OS
Flashing new version of TWRP
Flashing new version of TWRP blu_spark
Flashing new version of TWRP codeworkx
Flashing the ElementalX-OP5-3.10.zip
Flashing Boeffla-Kernel-2.0
Flashing blu_spark_r132
Flashing OSS 5.1.4
Flashing OSS 5.1.5
all with Magisk 17.1 installed
All with full wipes including the sdcard
The only thing that worked was installing OSS 5.1.5 with and relocking the bootloader.
Does anybody know what I have missed and how I can get the Safety Net to pass the ctsProfile.
Thanks in advance.

Relocking the Bootloader will of course work but you didn't need to do that.
What you missed:
That version of Magisk is clearly not working well with your setup and not hiding your Bootloader state properly. (Providing you set it up correctly).
Had you done all those steps without Magisk it would have passed. The custom Kernels alone would have gotten you a Pass due to them ignoring the Verified Boot state.
So, LOS+Kernel = Pass. If you need Magisk, try to find a version that is working properly with your setup. With Magisk working properly the custom Kernel is then optional.
Also, TWRP has nothing to do with it. Just use the latest Codeworkx.
Hi Dirk,
Thanks for your response, I have just tied to install it in the order you suggested
I install TWRP (twrp-3.2.3-0-20180822-codeworkx-cheeseburger.img)
I wiped everything including sdcard
I installed Element Kernel (ElementalX-OP5-3.10.zip)
I installed Lineage OS (lineage-15.1-20180903-nightly-cheeseburger-signed.zip)
I installed Gapps (MindTheGapps-8.1.0-arm64-20180808_153856.zip)
I installed a safety net tester called safetyNet 'attest'
When I run the safetynet test I am still getting CTS profile match: false.
Any ideas what I can do next to make this work?
Thanks for any help

You flashed the Kernel before the ROM, so you overwrote that Kernel with the LOS one. Flash LOS then the custom Kernel.
On Magisk.. i've seen many people complain that they can't get the latest version to pass Safetynet. Again, it could just be people not configuring it correctly, or it might be better to try the previous version. Just to make sure you should tell us what you do to set it up.
You need to Hide Play Store, Banking Apps etc, and Magisk Manager too i believe. If you install Magisk and set it up when your current state is 'Uncertified', you will need to clear Data/Cache on Play Store for it to change to 'Certified'.
Also, don't rely on 'Safetynet Checker' apps. If the Play Store settings say 'Certified' try an app like Google Pay. It should work fine.
If you get cts profile mismatch. Download CTS props config from magisk modules and you will pass
Download magisk 17.1
Hi All,
Just to give you an update one where I got to with this.....
You where right the newer builds of Lineage OS do not pass safety net but the older ones do.
So after much playing around I and many flashes and wipes I found it impossible to boot a Lineage with a custom kernel, I believe this is probably down to the forced encryption.
The thing that worked for me in the end was installing "MagiskHide Props Config" and changing the figure print, I am it is very similar to the module Jamie suggested.
So I now have Lineage OS working fully with root, magisk and passing SafetyNet
Thanks everyone for you help.

Hello; can you explain to me in detail, step by step, how to do it? Thanks in advance.

Fix safety net issue after magisk install ?

Hi. I have a safety net issue after following the rooting tutorial on this post. (to be precise, safety net was fine, i got the issue when i tried to install edexposed)
I've got a "cts profile mismatch".
I tried to get rid of it, uninstall magisk, wipe system, but it's still there.
I would like to try to make a factory reset using an ota file, but i can't find my version of the system.
I was on SKYW1907110OS00MP3 and i updated to SKYW1911010OS00MP5. Does someone have a factory ota update.zip for one of this two version ?
There is the MagiskHide Props Config module ( https://forum.xda-developers.com/apps/magisk/module-magiskhide-props-config-t3789228 ) for fixing this kind of issue, but there is no build-in fingerprint for the blackshark 2.
I tried to get one within an OTA file, but i can't find it.
I really don't know if i can do a << adb push stock_boot_b.img /dev/block/bootdevice/by-name/boot_b >> to restore the unpatched version of my rom or if that will brick my phone (or maybe do nothing to solve my issue)
If anyone have an idea, it would be great. Thanks.
Flashing the stock boot image of the ROM currently installed in your device will not cause bootloop. Tried and tested.
To pass Safetynet, you don't need to flash MagiskHide Props Config module. It doesn't really make your device pass Safetynet at all.
To pass Safetynet with EdXposed, follow these steps:
1. Make sure you enable Magisk Hide in the Magisk app.
2. Rename your Magisk package (optional - for banking apps).
3. Flash the latest EdXposed module from this repo: https://ci.appveyor.com/project/ElderDrivers/edxposed/history (the EdXposed in the Magisk app is outdated, and it breaks Safetynet), and the latest EdXposed Manager here: https://github.com/ElderDrivers/EdXposedManager
4. Go to EdXposed Manager's settings and enable App List mode and Pass SafetyNet options, then reboot your device.
Now, the trickiest part (sort of):
5. Clear Google Services Framework, Google Play services, and Google Play Store's data, then check for Safetynet. Sometimes, it still fails after your first attempt so just repeat this step until it passes Safetynet.
That's all. All of these worked 100% on my CN-converted-to-Global Black Shark 2 device. Hope it will work on yours, too.
Woot, thanks a lot, i will try that right away.
