Good afternoon. It is my first post. This group helped me a lot. Sorry for my English. I am using the Google translator to help me. I have a Bird Es1 scooter (in my country they are called Grin) and now they sold me one with a new version. Drv 318. I already used Es_ Downg trying to install all available versions and I was not successful.
What I have on screen is the following.
BMS Version: 136
BLE Version: 107
DRV Version: 318
Battery date: November 9, 2018
5200mAh battery capacity
Then I load the binary (whatever version it is) 139 to 151 and nothing.
Loading ZIP ...
DRV139 firmware name
DRV firmware type
Encrypted binary will be used
(Time etc) loading DRV139 ZIP
(Time etc) flashing DRV139
[Time etc) canceled ppr too many attempts
Any solution please? I would thank you a lot
