Please forgive me if this has been answered- but I have searched through all the posts here on the LG G3 and ADB and can not find a solution.
I have got this far following the guide on ADB Mac- but as you can see from the pic is says that my phone is offline. Changed the MTP to Ethernet to modem- and nada. Is this a facepalm and I am missing something here? many thanks in advance.
