MSSFLASHER Help (Bricked DME?)

[skristedja]

This guy sells BDM kits specifically for the MSS54/hp. I use it and it works great with his software. I think it was about $150 with shipping from France. I messaged him through instagram

Only solution in my opinion is to bdm it. Even the cheapest.

martyn has a nice little tool (dme utility) that shows you the flash slots that are free. If you flash with bmw flash you should take care of it. Otherwise if you exceed the limit, the dme will lock it self and you need to unlock/reset it with mssflasher or bdm.

Do you know if any of the above solutions in my previous post are on the right track? Or anything to do with terra recommending to ground the pin and force a boot that way?

Also are the bdm tools relatively inexpensive? Along with the process of bdm’ing the dme. I don’t care to pickup the tools to do it if it saves some more headache in the future.
Plus I’ve never been against learning more skills

So how'd it brick?

That I don’t know, I had a battery charger connected and voltage never dropped.
The only thing I saw amidst was during the virginize process was something along the lines of “no response from ecu” then completed the process

Not to hijack your thread, but what is this "count" you're speaking of? I've read and uploaded a couple of times via BMW Flash software and Martyns Ecuworx software but never noticed anything about a maximum amount of flashes you can do?

Write in one of the CSL dme conversion thread, some members have a bdm device. Maybe a forum member will bdm it for a small fee. I would help you, but I’m on a different continent.

Thank you, I’ll start looking and see if I can find anyone willing/able to help

I also stumbled across this service, https://www.bimmerlabs.com/help
Does anyone know if this would be applicable in my situation? Or would I have to send this out to get the bdm

Is this a potential fix for my situation as well? Cslregister.com/forum/showthread.php?t=12750

I am well outside of my wheel house here but I am trying to pickup as much of this information as possible. At this point I’d like to find the cheapest fix possible as HP variants do not seem to be for sale anymore.

Thank you so much for the help guys

Yeah that's bricked.

If you're willing to experiment a bit, if you ground pin 37 of the eeprom on both the master and slave while powering on the DME, it may boot to a state that allows you to flash the DME. Otherwise you're going to have to BDM the DME or flash the eeproms with an external programmer

Thanks for the speedy response Terra. not the news I was looking for but a solution I guess.
Is there any negative or further damage I can do by doing the forced boot grounding the pins? Next question would be if you could explain the process a little further for me. Would I have to remove the DME from the car and power using an external power supply? Or can I ground these pins while connected?

Do you know if this repair with an external programmer is something offered by third parties? Or am I left with most likely just replacing my DME?

Afternoon guys! I am having a bit of an issue with my car after using the virginize function.

I was testing a few different tunes and my count was getting low so I decided to use the function to reset my count. During the reset everything seemed normal besides a “ecu timeout” line followed by task completed.

After that I haven’t been able to use mssflasher to reload a base tune to my ecu and it hasn’t been able to communicate.
Does anyone have any experience on what I could be missing here?

DME is and MSS54HP and all of this was done while on a trickle charger and plenty of laptop battery.
I have completely restarted my laptop and cycled the key multiple times
