Okay folks,

Seems the last update from Bird will brick the control board. Do we think a straight up replacement of the control board will prevent the brick?

Or do you think the update hit the bmc as well?

[XavWolffe]

Further question. Is this update bricking the dash?

I don't think the update is affecting the dash. Once I flashed the controller, the dash works.

So you think it's just bricking the control board, cool. I have a new one on its way today from Amazon. I bought 5 Es4 units at auction last week and bricked 2 last night before seeing this update.

Is there a thread on flashing the control board? Or did I miss it earlier in this thread?

I'm pretty sure that it's just the control board. It detects a non-bird dashboard and starts sending garbage replies to it and makes it so it can't communicate with the Bird firmware'd controller. Once I flashed the control board, the clone dash works. I can even toggle sport modes on it. It still acts weird in that I have to hold the brake when I turn it on. If I don't , it keeps beeping and flashing tail lights. I haven't tried to fix the serial number yet and that might be the cause of the weirdness.

I had to solder wires to the SWIO, SWCLK, and GND. I used a hook probe to connect 3.3v on the ST-Link to one of the resistors labeled TVCC. Ignore the red circles:

I haven't had time to do the last two steps yet. Maybe that will fix everything.

1. Connect ST-Link to ESC
2. In STUtility press control B and disable readout protection
3. Open full bin file
4. Press CTRL+P and click program
5. Go to location 0x1FFFF7E8 Copy first 3 columns of bytes and replace at location 0x0801C1B4
6. Change ESC to original ES2/4 serial number

Solder in a piece of copper wire to bridge that gap and put it that b*tch back in service

I'll let you know, supposedly Amazon is delivering the new control board today. I'll let you know if that fixes it.

what bin file are you using?

esc139_fulldump.bin. I got from Scooterhacking.org -which looks like they are currently experiencing technical difficulties.

Quick question... if I have 2 36v batteries and run them in parallel, does that make the total output 72v?
