What Android device and cable are you using? Do you have a JB4 installed? And you're using the MHD E-series N55 app?

Howzit, I'm using a LG V30+ and a k+dcan cable. No I don't have a JB4 on. And yes I am using the e-series.

You may need a bench flash to unlock your DME if your DME version is MEVD1726. I don't know what the production date cutoffs for it are though.

We could most likely recover it remotely since you already have KDCAN cable. Will need a decent power supply, recommend 12+ amps.

I have an LG V30 and had similar results. I tried troubleshooting with an OTG troubleshooting app, when I plugged everything in it just showed that OTG was enabled, then it disabled. I also went to the dev settings and made data transfer the default and this didn't help.
I then Used my old Samsung S7 and OTG cable that came with it and had zero issues. |

Do you have a laptop with INPA/BMW standard tools installed?

At this point I'd almost have to say it's a hardware issue. Whether it's the DCAN cable, OTG adapter, device or a combination of these I can't say. I'd go through each one, preferably starting with the cable and adapter on a friends car and see if they can connect.
