I am able to successfully connect to and read my MEDV172 DME, but the MHD F-Series N55 App gives me an “unsupported DME” error message when I try to do the initial flash Stage 0.

Flash

Unsupported DME, version #
PC_HWEL SGBM 0257 v003_019_002
PC_BTLD SGBM 07D0 v003_019_005
PC_SWFF SGBM 07D5 v199_008_001
PC_SWFF SGBM 0AEA v199_008_006

MHD knows my VIN and said that my (production date 07/10) 535i would work.

I was able to buy the Flash License, but cannot do the initial Stage 0 Flash.

I would appreciate advice from anyone knowledgeable about this subject. Thanks

You're in the invited only beta right??? Because the official version for the F chassis n55 is not out yet.

[Dollar Bill 535]

Yeah, I'm in the beta group.

Cool, should've received an email with links to the group chat. Thought I would ask just to make sure you're in the beta and not using the n54 app or something. Let me know how it goes once everything is done.

How much longer before the general public can get this?
I can't wait!

Thanks, yeah I did, but didn't use Whatsapp before this so I didnt join at the time I got the beta invite email for the app.

MHD replied: "172 cars are f10 or f25, we have a couple dozens of those in the beta programm. All use the same rom family (0d07).
I noticed this week that there is another family of roms for some f10. Since this rom family files are not present in the current BMW oem database, and we have at least 10 f10 172 using 0d07, I thought that 07d5 was pre production or something like that.
Looks like it's not.
So we will have to port the tables and maps to this rom too."

You have an unsupported ROM that will soon be supported by MHD. Be patient, i think theyre working on porting to your ROM...

Been anxious about this since they announced it in December. Can't wait!

That's literally what he stated in the prior post.

Has anyone ever known of one of the early f10's with the 07d5 ROM to be flashed or updated, including a dealer DME software/firmware update?

Did they update this for you??

[Kwood-F10-535i]

Dealer should be able to update the ECU software but it is usually $300 or so they will increase you to the latest I-STEP

Hi, I'm clearly new on this forum (first post).
But I just want to let you know I'm in the same boat with the MHD F-Series flasher.

I've been working with MHD to figure out a solution. They say my ROM is not supported as it is an early F10 build (2010). Car is model year 2011 535i.
They have the bootloader and program (0257 & 07D0) already.
But, they need a copy of the calibration (0AEE), and probably 07D5.
They said they can add support quickly, but only if they can get the files.

The files should be in an "old" copy of psdzdata. Check the locations C:\Data and C:\Data\psdzdata for the following search *0AEE*.
The "newer" psdzdata files do not include this one.

If anybody has the file, send it to MHD. I'll keep looking around the web for it.

This is my software:
PC_HWEL SGBM 0257 v003_019_002
PC_BTLD SGBM 07D0 v003_019_008
PC_SWFF SGBM 07D5 v209_006_001
PC_SWFF SGBM 0AEE v209_006_002

I think it might be a case of being an early model with the MEVD17.2 (not 17.2.6) DME hardware.

I think you're right. My current I-Step is F010-17-??-??? Seems like this was done in 2017.

Just wanted to follow up on how my issue was resolved.

It is true that my previous I-Step was from 2017, but still wasn't new enough. Last weekend, I had a local BMW specialist do a software update to the latest 2018 version. The dealer quoted $300 exactly as Kwood mentioned. These guys did it for $125. Update the DME, EGS, and DSC.

After the update, the MHD app worked just fine. I loaded the tune and took it for a drive, and I couldn't be happier!
It pulls much harder and doesn't taper off at the higher rpm like it used to. Shifting is significantly faster at WOT, nearly as quickly as my sportbike. Looking forward to the drag strip

I recommend finding an independent shop that uses AutoLogic. They can provide the same software updates at a much lower price. Then, tune and enjoy!!

I was able to buy the Flash License, but cannot do the initial Stage 0 Flash.

I would appreciate advice from anyone knowledgeable about this subject. Thanks
