Hello everyone, @Athulnalin

If you wish, I worked on the issue and now it works (fingerprint and SafetyNet verification), you can find the change below: https://github.com/kdrag0n/safetynet-fix/blob/57b726c260bb40b838c5d942965282a5a482bdbe/zygisk/module/jni/module.cpp?plain=1#L134 safetynetriru is wrong, he must be safetynetfix

For information, the change present here (https://github.com/kdrag0n/safetynet-fix/commit/55f892fb8855a7867a186970e0bfc31e665ab183), will not solve all the problems once compiled. The change mentioned above must also be applied.

I applied the change on my fork: https://github.com/frnode/safetynet-fix/commit/dc3ec64eff578bc88aa6bb2970c026d71f9799e0#diff-e39ee2cf32c559774a334de83bb183fcd361c35bdd40c208cd809e1915df402dL134

I also compiled it, here: https://github.com/frnode/safetynet-fix/releases/tag/v2.3.0 If you prefer, you can also compile it yourself, with the docker I have also added (just launch docker-compose.yml) 🙂.

With pleasure ! 🚀

Works fine! Thanks!

@frnode Your build works perfectly with the new OxygenOS 12.1 build, however I still fail on CTS profile check, any ideas how to get around that?

[frnode]

@adwil13 Yes, device with the latest C20 update, there is a problem with CTS verification. I will look soon and I will update the fork if I find the solution.

@frnode both c16 and c17 had same issue, unfortunately I need Google pay and root on this phone ;) Got around this by spoofing OxygenOS 11 device fingerprint using MagiskHidePropsConf, however this breaks fingerprint again. So I had to revert back to original OxygenOS 12 fingerprint after setting up Google Pay. I did this before and it's a temporary solution as Google Pay will re-check safetyNet after some time, but It's good for now.

+1 props works but then fingerprint doesn't.

For complete solution that fixes both Google Play Certification, CTS profile and Google Pay please see: https://github.com/kdrag0n/safetynet-fix/issues/188#issuecomment-1147295375

Fixed in v2.3.1.

Fixed in v2.3.1.

Should both works - fingerprint and Safetynet? In my case FP works fine Safetynet not pass.
