For the past week I've been trying solution after solution found from the net to try and get my HTC One to connect to my computer and show up as a portable device. I'm running Windows 7 x64 SP1 with all updates possible, latest drivers and chipset drivers and even installed optional drivers to try and fix the problem. I've tried USB Debugging and nothing happens, tried uninstalling all drivers from USB device manager and reinstalling which also didn't work, tried installing MTP drivers seperatly, nothing happens, tried windows update's htc drivers, they fail to install every time.
My problem in short is, I cannot get my device to connect to the computer so I can use the storage space to add/remove/edit files on my phone.
I've recently tried a program called "DoubleTwist" which actually got the HTC Sync Manager to recognise my phone, but even that shows no storage available.
