I Have a problem. My RNEG2 didn't turn on (black screen). Only reset helped from time to time so i decided to make update (from 2.60 to 2.86). At the beginning of the update, when i saw screen with information if i want to "restart" or "cancel" update I chose "restart" and since then my radio has not started at all. I tried to reset couple of times and unplug cables connected to RNEG2 but with no result. Now, I have a feeling that RNEG2 works all the time (i can hear sound from inside) and reset (eject button) doesn't respond (until the update, after pressing the button a screen flash appeared). Only black screen. Any ideas? What is a safer solution? Factory reset (how to do this step by step?) or maybe replacing the microSD card described here [Only registered and activated users can see links. ]
