Default MHD Help!!! - 04-27-2017, 11:54 AM

So I've flashed my car tons of times and have had my fair share of problems, but have always figured it out.....

I went to flash my car the other day and got to 95%, then the flash failed. Each try since then it usually fails around 7-15%. I thought it might be my charger, so I hooked up my other car to it while flashing. Still ran into the same problem... I bought a brand new battery since I new my old one was going dead and put it in last night. Made one final attempt at flashing it, still nothing... I disconnected the negative terminal, and let it sit like that overnight. I wake up this morning and try to flash it again. This time it makes it up to 93% and then fails.....

I have no clue what else to do at this point, so any suggestions would be great!!!!I have used this OTG cable and Dcan cable tons of times, so I don't see how it could be either of those.

We had an OTG cable go bad and become intermittent, so I wouldn't assume anything.
