Flash OFW/CFW impossible
Posted: Thu Oct 24, 2019 3:43 pm
Good morning all,
I finally open this topic because it's been 2 weeks that I try to flash a firmware on an ESC of Ninebot ES4 ...
I have never seen this card before, the board is blue but also the cable of the dashboard is not present.
I recovered the cable of the old GPS to mount on the 4 pins normally provided for this purpose.
I cut a cable from the connector because it's a 5-pin base,
after doing this, I turn on the scooter, the dashboard "beep" but does not display the remaining battery.
I can connect in Bluetooth with Ninebot Flasher but I can't get SN info / Battery Version etc ... (Tested with windows and Android).
So I restarted the scooter and welded 4 cable to perform a flash with the STLink.
Flash OK, no error but nothing changes.
I tested to change the SN several times but it's the same result with any serials! (.bin used: "esc139_fulldump.bin" from this topic : viewtopic.php?f=6&t=14)
When I ride the scooter, it flickers quickly as soon as I move it.
The connections between the dashboard and the ESC are good (tested with multimeter) and I have tested the dashboard on another scooter and it works very well.
Does anyone have an idea, did anyone ever see this model card?
Sorry for my little english!
Thanks for your replies
