modern_citizen24 · 09-13-2015, 05:19 PM

Car won't flash getting hw:ffffffff then when it does decide to start writing it fails at 8% and says can't write packet 516 and various other packets. Tried flashing back to start and can't, car won't start and lights are going haywire. Assistance needed!

Phone on airplane mode? Did you also try resetting the battery and doing it again?

When I first flashed the backend on mine I did the following

1. Attach a battery charger in engine bay
2. Put JB4 at MAP 0
3. Turn off radio, HVAC, lights, close door etc etc as the only thing you hear running is the fuel pump when flashing.
4. Ensure that you are using A DCAN cable for the flashing, were you able to make a backup of the ecu?
5. Phone on airplane mode

Ensure that you covered the above ?

I don't have jb4 my car charger is hooked up, I followed everything then tried different variations. I was not able to make a back up but from my understanding mhd stores your stock settings? And phone was on airplane mode. Thanks for the reply. Is it normal for the cable to write only a small percentage of the file even if it's a bad cable?
