NefMoto

Have an ME7.5, MTM chipped 518F box that I'm trying to IMMO defeat:

I have been unsuccessful in getting into boot mode though and would appreciate any troubleshooting tips.

I have a purple eBay cable configured as such:

Bench voltage is 13.5.  I've tried grounding the boot pin (24) for various lengths of time from 2 to 10 seconds but  I keep getting an immediate 'check cable' error - very quickly.    I believe the cable to be good though, as I can connect via OBD with VAG Can commander.   In addition, it is recognized by the Nefmoto flashing tool and connects via OBD with the Nefmoto tool.

No communication over OBD either, though it at least pauses for about 2-3 seconds before giving me the FAIL:

Hopefully, I'm making a simple mistake somewhere......

Thanks in advance.

try it with baud rate of 57600
Can you see the underside of the mtm board?

thanks, I have tried all possible baud rates.

anything in particular you're looking for on the underside of the mtm chip?

remove the riser, put it in boot mode, flash the eeprom, replace the riser.

special tools required or just a steady hand and patience?

same nyet as over on Audiworld?  ;)

thanks.

It might slip right off. I'm not sure soldering is needed

It's clearly a simple socket. Pull gently and evenly.

Turns out the bench harness I was borrowing from a reputable forum member had a fault in it.  After reconfiguring it, I was able to download the 95040 on the first try. 

Now, could someone assist with IMMO OFF please?  ;D

I'm sure someone will help, but could you please just try,

^ x2. Daz's immooff bin worked like a charm on my 518F.

thanks for the tips so far, was able to verify checksums on my immo defeated .bin.  Now, I'm back to needing any boot mode tips!

So close, it seems!  I've already tried all possible baud rates.  I found an old post basically saying - "keep trying, ME7.x is stubborn."
Any other "variables" you'd recommend changing.....file name?  location of the program?  Thanks.

TRY IT IM SURE IT WILL WORK. IT ALWAYS REPORTS THAT ERROR WHEN I USED IT BUT ALWAYS WORKED FINE

WHAT PLEASE SPEAK UP

YEA IT ALWAYS DOES THAT!


Why are we yelling now?

mine never does not verify correctly. using kkl and rosstech hexcan cables.

I dont think mine has ever verified correct, but then again i'm a idiot.

"mine never does not verify correctly. using kkl and rosstech hexcan cables."

So you always get verification is what you're saying?



Anyways, thanks for the confirmation marty and carsinc - the write seems to have worked, and I was able to start the car, no immo light. 

Hey it worked who cares if it verified?
