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!

E035 error after following instructions and firmware update loaded onto bike successfully. Basic app works but premium involves loading an unverified apk file (Android) then adding .dat files within filesystem. Fiddly setup and ultimately didn't work. EP8 RS motor. --== update: thanks for the feedback. haven't had time to tinker with it - will update soon ==-- UPDATE: Finally got around to troubleshoot again. Emailed the developer of the app and resolved it. Quick response. Kudos.

You must update firmware to the latest version after the derestriction on EP8 RS. This is why you got that error. Once again: downgrade -> derestrict -> upgrade!
Any feedback?

Great app and communication by the developer. Instructions easy to follow. I was using a Samsung S21 to tune a Shimano EP8. I grabbed the Solid explorer app to transfer to the files into the android data dir. Firmware downgrade was simple and you can still update back to the latest version after making changes with this app. Remember to go into airplane mode and turn Bluetooth on. Bike is how it should be out of the box now. So good! Highly recommended Stunlocker.
