How to reset sevcon gen4 controller

[jonsina]

I bought DLC28 me1302 motor , sevcon gen4 size6 550A set about 2years ago.
but I did programming by DVTC but there was something wrong in process so the controller doesn’t work now

first the controller flash long green light and blinking twice

I tried several things from enless sphere forum to unbrick my gen4 size6 but everything wasn't work...

also I can't find any dcf, dld files in my laptop and DVT says

"Error putting node 1 into preop" when I tried to enter bootloader mode.



Is there any ways for reset controller???
