Yes, I have it. Email me.
p.s. After Shimano and his lawyers fckd my brains out for six months, threatened me, blocked the STEPS Unlocker app, wanted to take the domain and even the stepsunlocker gmail mailbox I don't want to put anything like that in the public domain on my behalf. Apparently...
Yes, because when shimano got into the fight against de-restriction, for EP8 there was only 4.0.2 firmware (actually an alpha version), and all subsequent firmware for all motors was with "derestriction" blocking via Bluetooth. For all older engines there was already quite working firmware. EP8...
Yes, sure
4.0.2 is required for changing settings (region, circumference). Don't use the bike on 4.0.2, always upgrade to the latest firmware version after the derestriction
I don't think so
Who knows
Yes, finally, after 5 years of App/Software developing they are protected their App/Software... Also they changed authorization logic on EP6/801, this is why they are not supported yet
They added some additional checks to avoid downgrading

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.
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.
