I've inherited a Galaxy S II running Android 4.1 (no software updates are available for the stock version), and I want to put 4.4 on it. There are plenty of tutorials for this on the internet, but most of them seem to rely on flashing CWM with ODIN first.
My problem here is that USB Mass Storage doesn't work on this phone, and hasn't for about a year now. It will charge over USB, but doesn't appear to acknowledge being connected to a PC. It shows up in Device Manager as Unknown device, and in Properties it says Code 43: Windows has stopped this device because it has reported problems. If I go into settings on the phone and try to switch on USB Mass Storage, it tells me to Connect a cable before using USB Mass Storage (or similar wording). I've tried with USB Debugging on and off.
I can, of course, copy files on and off of the SD card using an external reader, what I want to know is whether it is possible to go from stock android (and stock recovery) to CyanogenMod 11 without using the USB connection? If so, how?
