The "unmounting" may work when you're having issues. My brother moved some apps to the SD card and that's when his issues with Z4 and wireless tether started. He moved the apps back to the phone and all was well. I'm running without issues with v.2.0.5. My brother had the exact issue and when he changed the version of wireless tether he was sorted after that. Maybe downgrade to 2.0.5 or 2.0.6. Actually i remember his issues starting when he moved "random" apps to the SD card,when he moved them back he was ok. So try a different version of Wireless tether or try unmounting the SD, or if you moved any apps to the SD card, move them back. I know this seems like a lot of different things but he did all of the above and he got it working.
