Hi folks,
I tried to flash MHD stage 1 last weekend - but failed
Setup:
We flashed the car back to stock (864416) using the tool of evil (I*P*) and after that we could repeat the above again (i.e. errors are reproducible).
We did not touch the tablet or anything else in the car, kept doors open to not interfere with anything else during the flashing procedure.
Any hints what we need to look out for? We will try another android device and also try a different cable, but somehow I feel that this might not be the source of the issue.
Now I am back on PPK SW, so I have at least some more power
... but having all the stuff in place I want to get MHD now up and running.
Any hint appreciated
Cheers
Carsten
I tried to flash MHD stage 1 last weekend - but failed
Setup:
- proper charger in place
- proper K+DCAN cable and OTG cable in place
- Samsung tablet A6 w/ all SW needed (apps 400MB RAM and 1.7GB memory left)
- unmodified car (no FMIC, no DP)
- N55 from 02/2010 (must be one of the first ones)
- Key FOB in slot (though keyless go), ignition on
- DCT in P
- Radio, aircon and headlights off (including angle eyes)
- trunk, hood and doors open
- cables connected, tablet in airplane mode
- check connection via "read DME codes" - no codes detected
- start flashing procedure (TUNE - FLASH A MHD MAP - STAGE 1 98 RON v0.20)
- fuel pump starts, different noises from the engine bay, error messages in the i-drive. Charger tunes up to appx 20A. Everything seems normal.
- after a couple of mins following message: Failed to write ECU. Unable to erase memory. HW FFFFFFFFFFFF...
