Sorry for the delay, I believe we already replied to your email to support but just in case here’s some things you need to make sure for LD/NOX works with DH2.
Make sure to open DH2 first before your emulator. When you open an emulator, the integrated AHC should automatically pop-up and patch it, wait for it to say ready before opening the poker app.
As for LDplayer, make sure root is enabled and to use open connection.
