You need to have the old firmware, which they can send you the instructions on how to revert back through Bluetooth on your phone. Once I did that the software worked as advertised. Keep in mind the initial cost of the software is not the final amount. It's an additional $38 for unlocking all the features of the software, but it is worth it and it will truly derestrict your Shimano ebike. Unlike a piggyback, you actually get the full use of your mph on your display. Follow provided directions!

I got into trouble trying to connect to a bike I'd purchased that had STU loaded. With assistance from the STU developer i soon got it all working. TIP: Once u use E-tube app to establish a NEW connection between your phone and the bike, do NOT OK E-Tube to upgrade the motor firmware, as it will load a more modern version that will kill the Premium version of STU. Stick with the existing motor firmware!

Thanks. But, the firmware upgrade will not kill the "Premium version". With the latest firmware versions it's not possible to change advanced settings via Bluetooth. So, it requires to downgrade to a supported FW version. But all motor's settings remain the same after applying the latest firmware.

Great app, extremely user friendly and intuitive. I find the sandard Shimano app is very slow to connect and very limited in terms of adjustments. This app gives much more flexibility in tweaking the settings, even with just the standard version. Well done to the developer and thank you! Should I decide to ever want further changes then the full licence seems great value as well but I'm happy with the standard for now. (I'm running a Shimano e8000 with Di2 gears btw)
