So i was reading this thread back from 2018 and they recommend this module and also said if i pass safetynet test i would most likely be "play protect certified" too?? i want to fixed this play protect not certified issue so i just need my previous valid release-keys is that correct??
If you pass the CTS profile you can get your Play Store to be certified (might have to clear data for it first though).
If you're using a custom ROM you need to use a certified fingerprint (there are loads of them included in the module, and in the docs you can find info on how to get one if there isn't one for your particular device). And, if your device uses hardware backed key attestation you need the new Universal SafetyNet Fix.
