Install the latest version of the program (If you have problems with the firmware, use version 1.7).
Model A1 / S1 / S2 can reach speeds of ~ 30km / h.(MUST HAVE TWO BATTERIES!)
To install the hack, you need to open the program, click "Start scan" and wait for the phone to scan the bluetooch devices around. If the wheel is in the program's action field, you will see it in the list of found devices. To connect to a wheel, click on its name (It may take a while).
Then press the "Get Key, Sn" button, and on the opposite to the 3rd key, the copy button. The keys and the serial number required to generate the confirmation code are copied to the clipboard. Contact me in a convenient way and send this data.
