  • Just to make sure you hit 7 times on the `build number` to unlock the developer mode – Zain Jul 04 '21 at 20:21
  • @Zain, thank you, I try to hit, but receive message - no need, you are already a developer – Alex Jul 04 '21 at 20:50

Redmi 9 (9A etc) has driver issues when enabling USB debug, plus many of the dev options are locked and need to be unlocked via a specific procedure that the phone will present itself. Almost all drivers required for Redmi phones,(mediatek,qualcomm,android) are very finicky. Have you fully unlocked your device?
