MSS6x Flasher - Now released!

[omhl]

ahh i see.

seems like Winkfp (update) does the same thing. So if I was already on 241E seems like most programs out there like winkfp and autologic etc will only write the tune portion of it. Just a PSA if anybody is wondering.
Now I'm wondering how to force a full program reset. Maybe I have to downgrade and then upgrade.

Just for fun I went back to 241E program with autologic. It seems like I don't need a RSA bypass despite going back to stock?
When I try RSA bypass, it says the full read after autologic was not stock.

I could go straight into flashing my tune and car starts up okay. Is the RSA bypass somewhat permanent?

Did the autologic do a full program write or did it just rewrite the tune? Full program write should disable the RSA bypass. Tune write will not.

Okay, so definitely a K-line car and there's nothing even going to the CAN-pins to cause an issue. Could be a bad cable, hard to say with certainty. I'll run some tests tonight and see if I can figure anything out.

Just took a look. Only populated pins on the vehicle connector are 1, 4, 5, 7, 9, and 16. All others don't even have wire receptacles.

Hmm that’s a tough one, I’ll try to replicate.

Does your OBDII port have anything going to pins 6 and 14?

[CaptainPunPants]

Oh yeah, failed to specify that. Can confirm, both cables had the latency timer set to 1ms.

[terra]

So something is failing when it's trying to write to the external flash. To be honest I haven't messed with the slow RSA delete too much so maybe I missed something there, so I'll double check that.

In the mean time, I'd double check that your cable's latency is set to 1ms in device manager - especially since your old cable worked with WinKFP (since you have an 06 car the Bimmergeeks cable isn't strictly necessary, but it's still good to have around for newer cars or if you end up doing a bench flash using the D-CAN pins directly).

Hey all. Just got done attempting this with an 06 M5. Short version: semi-bricked at RSA bypass, un-bricked in WinKFP with some headaches/sweating.

Used the Bimmergeeks pro cable (with the switch) and a Deutronic DBL430 set at 13.6V.

Before getting the cable, I successfully did a full read with my old K+DCAN cable (had an adapter instead of a switch bridging pins 7+8). I backed up the ~5MB binary file and tune.
Created copies of the binary, loaded into the binary modification tool, it recognized. Purchased a single-VIN license, created some modified binaries to test it out.

The bimmergeeks cable arrived, and I started with an attempt to read the ISN. It failed (as expected), and recommended the RSA bypass. I attempted the slow version (since I have no experience outside of diagnostics and coding).
Failed after erasing the ECU: "Failed to set flash address @ 0x450000" (image attached).

The ECU would still identify in WinKFP, and attempt to flash. However, the flash was failing to take last night. Partway though the process, it would cycle out of flash mode and abort. Usually citing a security access error when trying to switch programming mode. Checked in ISTA+ afterward, and it would load the module tree and list the DME as blue (ECU with aborted flash).

Tried the Bimmergeeks cable this morning, with the toggle switch in the other positon. The flash took, so I foolishly decided that was the problem.

Tried the RSA bypass (slow) again, and got the same error (failed to set flash address). That's the image below (I didn't take a screen shot last night, but I believe it failed at exactly the same point).

Tried WinKFP again, and I could NOT get it to take the flash. It would keep getting error 211, usually citing a security access problem prior to aborting the flash, at varying percentages (never failing at the same point).

Finally ran it with my old K+DCAN cable today, and it flashed successfully. The car is back where it started now, un-bricked and running.

I haven't tried the MSS6x flasher with the old K+DCAN cable, as I'm not sure if it has the proper EDIABAS firmware. (I paid a premium for it in ~2011 or 2012, it's listed as INPA compatible on the label). While my car is old enough to (probably) not be subject to the bug, I wasn't ready to take the risk ("not thoroughly tested" was enough to convince me to shell out for a 2nd cable).

Have I stupidly failed to properly set something up for the RSA bypass? Or is it possible I just got a spotty interface cable?

Thanks again terra! For now, just updated ecu software to 241E. Verified the before and after using your application. Will take a full read later on.

I got a response from bimmergeek by email
If it helps someone who receives their cable,
Martyn Thanks to you too who helped me on Facebook,
terra Thank you so much for helping our little community

terra Hi✌️
thank You very Much 🙏

If your car was built before September 2009 it shouldn't matter. If it was built after that, communications will work in one position and won't work in the other position. So pick the one it works with.

Or if you have a multimeter, check the continuity between pins 7 and 8. You'll want the position where there is no continuity.

Sorry for my english 😅

Hello everyone,
I received my bimmergeek cable, there is a button behind it, we can press it in high or low position, is it the right position to flash my MSS60 and MSS65 please?
