[Xiaomi Mi Max ROMs, Kernels, Recoveries, & Other D] franesh:

Use Magisk 19.5 (canary build)

If you use Magisk 19.4 you'll get bootloop

Migrate wont work on Android 10. As Android 10 use system as root. No way other than installing apps one by one from play store . As far as I know this is the only option in Android 10

A little progress update:

I have already fixed the fingerprint issues since previous build, it was a bug from LOS, and I'm working on KeyDisabler problems now.

For those who was facing VoLTE calling problems, unless you give me the logs otherwise I can't test it by myself, so reporting such issues without any details or logs are just useless and please don't do it.

Thanks.

That's awesome.. didn't know that.. I am planning to buy the India version and use it on T-Mobile.. not sure if it will have those 2 features... It at least has VoLTE for Indian carriers, so I assume it should work on T-Mobile also....
[ASUS ROG Phone II Questions & Answers] docfong:
At this point I wouldn't buy anything till others try it first. There is no guarantee that an India version will do VoLTE or VoWiFi on a USA carrier.
[ASUS ROG Phone II Questions & Answers] DarqAnshin:
I could be wrong. But I do believe that the VoLTE ability is carrier specif. Phone manufacturers have to be on the approval list and be able to use the correct bands. In the United States, I also believe that the manufacturers have to pay to be put on that list. I believe it was another thread in this forum that stated something along the lines of 250k (but don't quote me). EU and Asia's markets are handled differently.
