Hi, I started already a topic that's about hacking a TIER scooter. I removed for the first the black gps box in front of the scooter.
I don't know if it has an additional battery inside so I placed it inside a bush. I don't know how long the battery will stay until it dies, but I will wait some additional time. After that I will try to disassemble the gps box to see how it works.
If you wan't to stay updated, visit my thread "TIER scooter hacking". We are trying to understand how the unlocking mechanism works. And if we find that out, we will bring this forum much, much further.
