Hi guys
That's my point of view on Lime ninebot
Green GPS box has two cables, one with cap on it is USB and debug UART , second one connected to ninebot control-board is DC and UART, its powering mobile unit with GPS and communicating with control board.
Control-board of the lime-s is blue with DC UART socket to communicate with GPS.
You can not bypass or change cables to make it work because it is all digital, problem is in blue board what has custom firmware [original ninebot has green board without UART ] that's communicating only with GPS unit, this firmware has turned off Bluetooth on the dashboard to make impossible to upload own firmware, you can do it only by JTAG. If you disconnect GPS unit and power on the ninebot you get only error message [that's not to bright to see it over dash cover] with wrench key and temperature indicator [or what is it] and scooter is in locked state impossible to move it, its applying electronic brake if detects move and beeping .
Dash board is seems to customized only by design with green power button with mechanical block element that's blocking power button to be pressed but you can easily remove it, other parts looks same like original ninebot .
Now i waiting to new main board arrive from China and try it to put new life in it.
If someone of you has a Bird ninebot [or Wind, Tier too if are you in EU or Israel] you can post photos of control-board and dashboard to make our knowledge stronger
And for those who have theory to change SIM, do not do it, SIM is only medium if you change the SIM the MeiG board is still calling same server but some interesting info, Lime in EU using US T-Mobile SIM card
i want to know what roaming plans they have ...
