Yes, I did. They haven’t replied to me today other than - from earlier yesterday “Make sure to have car play fully deactivated”, “Then flash again”, “You can’t have CarPlay and flash with mhd it will cause an failure to the flash”. That’s it.

my CarPlay was off and in airplane mode
Who did the unlock? FEMTO direct or a company that 'hand delivers'? Reach out to them? Seems like you said; everything in working order and car doesnt want to start.

With the flash back to start, did you clear all codes? Try re-seating the ECU plugs? Disconnect battery again?

Figured out the issue. I contacted Femto. They said my DME was unlocked for bm3 only. Even though I had contacted MHD and they said MHD (not MHD+) would work on my car. Femto said I will need to use bm3 to flash it back to stock or one of their maps. As flashing back to stock using MHD doesn’t work. Even though the OTS & stock flash was “successful” according to the MHD app (which it may of been)but at the same time it’s not compatible with communicating/registering with my DME from the other end. (Femto doing their thing). The MHD app also detected and unlock but at the same time doesn’t mean it will work with the DME if it wasn’t unlocked for MHD specifically. I’m looking into sending my DME out for a MHD+ unlock instead of using bm3 to fix this as I prefer MHD in the long run to resolve this issue. After a unlock for MHD I’m hoping the car will run again, although I need to double check if I need to flash the car again or just install the DME and try running it.

Wow - are they covering all expenses for this?? Seems like it should resolve it. Darn

No, it’s not Femto fault. Originally I had it unlocked for bm3. The guy I was working with considered using bm3 but I now prefer MHD. So it’s really no one fault. A lot of miscommunication and some lack of understanding too between the middle man and some associates. Going directly to Femto for help cleared a lot of these issues and lack of knowledge.
