I was able to flash bms by first unhook power or letting the battery die, unhook the 12 or so wire cable the connects to the bms, the led will stop altogether and you can backup program memory and flash it, although i wasn't able to backup data memory until after I flashed program

Okay i figured it out the bms had to have the 2 plugs removed to cut power and comnected to stlink without issues.

The Dashboard I have looks the same but has different color wires from the bottom connector. can't seem to find a picture of the back side of the G30 dashboard used in the tutorial so I can figure out the order the wires attach to the connector.
When holding it vertically and looking at the back the connector is at the bottom and the colors from left to right are ORANGE YELLOW BLACK BLUE...
best guess I can make from a picture of the front is that it is BLACK YELLOW GREEN RED

any ideas?
thanks!

The flash_BLE555.bat will not work as is!

You have to change the line so it reads like this:

bin\openocd.exe -f share\openocd\scripts\interface\stlink-v2.cfg -f share\openocd\scripts\target\nrf51.cfg -c init -c halt -c "nrf51 mass_erase" -c "program full_BLE555_upd7.1.bin" -c "program UICR 0x10001000 verify" -c "reset" -c "exit"

Currently it is missing the word "program" which causes it to fail! This will also prevent your dashboard from powering on if you try to flash with the incorrect command. I was able to redo the flash and it worked after I made the change.

FYI also the 555- while it does flash and seems to work- does not allow me to flash anything with xiaoflasher. I reflashed the dash with flash_BLE110.bat and this works great and allows flashing over bluetooth.
