I have an old HTC Vivid I want to use as a datalogging device in my race car. It doesn't have a SIM and will never be on a 3G/4G network again. I do, however, want to be able to turn-on the WiFi hotspot feature so that I can transfer files to/from the phone using my laptop without having to plug it in; or have a WiFi router present.
I tried JellyBelly's script, but I keep getting a phone.apk FC. If I turn on airplane mode, the FC's stop. So, then I turned on WiFi. But, with WiFi turned on in airplane mode, the hotspot feature is grayed out.
So, I'd like to make a custom CM11 build for WiFi only. Is it possible? Any pointers to a how-to thread?
I suspect that maybe the Hotspot feature only works with a cellular network connection. I hope not...
