after you get the code, you need to modify the entry in pref.xml as front page mentioned, don't modify the wrong path, got many pref.xml in many folder, is the one in storage folder

change the CC to your country code
enter your phone number without country code
I didn't change the regstep and remain as 1

restart your phone, cause java won't close the program automatically, a clean startup will be better. start the program, switch to login, and verify, it will ask for your verify code, enter it and it will start.
