Yes, after switching to English I could train the voice model.
After that google is asking wheter to make it active.
I confirmed and then it is greyed - as before.
Switching back to my native language google is saying that the voice model is already exisiting - no need to train.
And it is...
I was just trying to unlock my Mi8 global after 360 hours.
The following message showed up in Mi Unlock (latest software revision);
You need to use your device a bit longer to proceed, Try again in 7 days.
Any ideas why and any solutions ?
Or did I something wrong ?
I had to reboot several times until I got the right TWRP
Then wipe data and installed the ROM.
It was hanging at the first reboot, so I made after 1 min a manual reboot.
And everything was fine...
