Hi, I am from Hong Kong, I have did a lot of review before try to flash my car with MHD, and I finally decide to flash it today, but my flash didn’t went well and my car can’t turn on anymore, this is the process of my flash, hope that you can help me.

First, I have my battery connected to my car, then I pug in the K+DCAN cable, it connect successfully, I purchases the flasher module and stage 1 map, then I go backup my ECU and start flash the map. Firstly it go well, but then it stuck at (15%, 31min) left. I wait for more than 1 hour but it still stuck at 15%, so I have choices to unplug the cable, then I restart the phone and ofcause my car can’t start anymore.

After my phone restarted, I try to flash my car back to stage 0, the MHD app go well and start flash back to stock, later on, it stuck at (89% 2min) left again, after half hours, I have no Choice to unplug the cable again. Finally, the MHD app no longer connects to the ECU, I try with the same cable that I have used and it said no cable detected. That is all the process of my flash, hope that you can give me some help, thanks.
