Seriously how hard can it be?

What color is the wires going to the lock and where is it hooked up to the EMC/BLDCC?
Any knowhow about if it's just an solenoid or any type of controler circuit inside the lock?
I do know es400 have a 3.3v "brain" inside their locks. ;)

The ESC has battery, motor, backlight ,hatch lock, and main connector.

The connector is exactly same as the dashboard connector. Blue and 4 pin. You can fit the dashboard connector in it.

Okay so 4 pin connector for hatch then?
Maybe similar to es400 (pic above) then...
Sounds like it maybe have some kind of "brains" then...f*ck :| :x :evil:

Do you have any opportunity to take the hatch lock apart and look for the electronics?
Snap some pics or so?

Had planned to inject voltage to hatch somehow, and cables for ESC to tight to investigate easy... :(

Can you tell where it's connected on the ESC?

My friend brought an vandalized "base", don't have any means of drilling right here and also don't want to do unecessary damage to it.

Much appreciated :D

It has its own connection on the esc, not connected to anything else

Great pic :)
But the white "thing" is not in the right position right? It looks like it blocks one of the skrewholes? Is it mirrored both on X and Y axis?

I can't get a real grasp of how the lock mechanics work yet, how the electronic actuator releases the latch.
What color is the wires going to the lock and where is it hooked up to the EMC/BLDCC?
Third time's the charm.
Maybe you didn't catch that, was a lot of questions. :mrgreen:

Is it here? Am I right about the connectors? And what's the others connected to?
Image

Haven't got the hatch open yet so I can't follow the wires... :roll: :(

How can I Flash the scooter ?

Is it Easiest with:
ST-Link-route:
ST-Link (or NXP nRF- dev-board, I flashed ES4 dash with back in the day :) )

Then I Flashed BLE555 to dashboard (with dev board) first, then flashed everything (ESC, internal/external BMS) via ESDownG
Or
IAP Ninebot route

Possible just with computer, usb-TTL and the IAP-software?
Would this thing work, is the scooter 5v-tolerable?

Can you manage to just flash just dash with IAP?( I know BMS recommended.)
How do you flash ESC with IAP, can't seem to find that in any guide...

I played around and managed to flash the esc and everything so that it works like regular ninebot now.
You can't flash it without having the iot box connected.

Can't figure out if the loop is connected to the lid with rivets or epoxy of some kind.
It may be possible to drill out and then reattach?

The white part of the lock (actuator) has brain in it, better drilling those 4 screws, also there seams to be epoxy between the lock shackle plate screws and top cover.. Just drillet the sh*t out and it fell out...

Tried drilling that lock plate in the lid, but pretty hard so broke my shitty drill.
Will need to get a better drill get the thing apart.
