Bricked ECU
uhm, i think i bricked my ECU. I was installing my V5 tune, in the middle of loading it and accidently kicked the cable and it came off. Now my car is in Inoperable mode. Try to upload the recovery setting on the hand held but it didn't do anything. Such an idiot! Anybody have any ideas? i"m going to call Eurocharged in the AM

Did you go all the way through recovery mode? That stupid handheld takes like 15 cycles of ignition on and off to fully load recovery mode. Its not complete until it says write complete or something.

most times you don't have the proper battery voltage to complete recovery. Hook up a battery charger, let it sit a bit and leave it on and try again

It's not bricked and it's not your battery. Your ecu is locked up and you need to go to MB to get them to re-write your original ecu program.
I did something similar...felt stupid but everything got sorted out at the end.

Edit - I did send my ECU to EC first and Jerry opened it up to see if he could flash it back, but was unsuccessful. That's when I resorted to having it towed to the dealer. You may get lucky and not have to.

I'm not speaking based of hearsay. This is firsthand experience.
OP - EC may be able to send you a stock map that might be able to recover the ECU, but in my case it didn't work and I had to tow my car to the dealer. Both, EC and the dealer were very helpful.

I love the armchair mechanics on here.

OP asked and I answered. This won't be the first time Jerry has seen this issue. But please, enlighten us with more pointless banter. You seem to be pretty good at it.

Chances are you didn't brick it. I was tuning my car and had the EXACT same thing happen didn't have it hooked up to a battery charger and it died in the middle of tuning it. You need to have it on a charger the voltages are very sensitive.

For what it's worth, here's my story. After locking up my ECU, I towed the car and had MB re-flash it. I called up Eurocharged to go with me through the process step by step while on the phone.
At no point did they ask me about my battery or tell me to hook it up to a charger.
The whole process takes about 10 mins...our fans will go on for a minute or two and if that kills your battery or affects your voltage, your battery is probably well overdue for change.

...After Eurocharged already stepping in to help to OP solve his problem.
...Which he did the EC way and spent precisely $0 at the dealership to get his car back on the road.
Sorry you had to go through that experience though. Must have been frustrating running your car all over the place.
OP -- You get out there for a drive yet? Any thoughts? Not sure where you are located but keep in mind that just because there is no snow on the road it doesn't mean you should just romp on it, especially if it is cold. Someone else already had to learn recently that temps effect tire performance and not just what is on the road.

Nope - In my case, EC and I tried everything we could that wouldn't involve the dealer. The recovery mode would quit during the loading process, even with a battery charger and having my ECU sent to EC for them to open up and try manually (which they did at no charge) ended up not working, all this so I could sell my 2010 and get into a 2013. It finally came down to the fact that my ECU was completely compromised and had to be sent to the dealer for a complete reset. They just charged me 2 hours labor to get it back to stock.
OP - glad you came out unscathed. You are one of the lucky ones.

It must depend on what process it's at when loading the tune. Do you remember if it was during the actual write process (when you see the progress bar and the fan is running)?
