MagiskHide is one of many basic action needed to be done but it isn't the whole solution ( not even close).
After many reboots I found that the solution is one or both of the following:
- install Magisk module "safetynet-fix" test2 from HERE
- Since EvoX latest 13th Jun release has May 2021 security patch, it is only logical that because MHPC latest certified fingerprint for 9T PRO is still "Xiaomi/raphael/raphael:10/QKQ1.190825.002/V220.127.116.11.QFKMIXM:user/release-keys" the 'ro.build.version.security_patch' needs to be force set to "2019-08-25" ( as I mentioned before)
- Use MODDED HiddenCode module (see my older post for link) exposed module.
