• Warning!!

    Riding a tuned or deristricted EMTB is not a trivial offence and can have serious legal consequences. Also, many manufacturers can detect the use of a tuning device or deristricting method and may decline a repair under warranty if it was modified from the intended original specification. Deristricting EMTB's can also add increased loads for motors and batteries. Riding above the local law limit may reclassify the bike as a low-powered bike, requiring insurance, registration and a number plate.

    Be aware of your local country laws. Many laws prohibit use of modified EMTB's. It is your responsibility to check local laws. Ignoring it, has potential implications to trail access, and risk of prosecution in the event of an accident.

EP8, have successfully downgraded to 4.0.2 as per instructions. Connect with ST unlocker and premium license no problem, but when I try to change the market settings to US (from EU), or circumference for that matter it says it has done it but immediately defaults back to EU and default wheel circumference.

Anyone seen this happen? re-installed ST unlocker, same problem.

First time I saw the same issue few days before from other customer. He was able to fix this issue by unpairing a bike in Bluetooth settings. I have nothing more to help you (if you really have FW 4.0.2 on your bike). The App works for all the other thousands of my customers.

Are you Sure you are on the right Firmware ? Because i think thats exactly whats Happens with the newer Firmware where Bluetooth Modifikation is blocked.

I think I understand who you are. You're the person who paid for the license and then demanded a refund and got it. So it's not surprising that the App does not work with your serial number.

I don’t believe I was refunded but will check it now, I had no means to apply old firmware hence the original refund request. I have since acquired an android phone for this purpose following the support feedback. If it was refunded, happy to purchase again obviously.
