Apparently UMS is no longer used in Android, and MTP as I said is unreliable. Does anyone know of any workaround that would solve this problem? I hate posting a question that I know has been posted before, especially as many times as this one has, but nothing I have tried has worked, and I have always used my phone and sd card as a quick thumb/zip/whatever drive, for whatever someone might need a thumb drive for. I have tried asking this on the CM Skyrocket forum, but for some reason not only can I not post new threads, I can't answer already posted threads or contact forum moderaters/admin in order to find out why.
I know there is always the wifi option that will always work, problem is I don't use wifi, I actually use my cell service as a tether/hotspot in order to connect. So there is no network to use to connect with. Setting up a ftp account is just not feasible as I need to use multiple computers throughout the day.
