Didn't work. Still don't have baseband. I tried this because since an attempt to flash a 4.3 ROM soft-bricked my XT926 I've not had any connectivity at all. Have tried all the recommendations to restore stock ROM and have tried varied methods and ROMs and still no connectivity. Thought maybe flashing the radio would help and was glad to find this. But I followed all the steps and still nothing. I tried it on a stock ROM and on the last ROM I had that actually worked (and is still worked, except for the connectivity), but still nothing. Does anyone have any ideas what might be going on and what might fix it? Thanks.
