kay guys I am using a Rooted Samsung Galaxy S2, on gingerbread. I use it for tethering... Unfortunately the wirless tehering on it has always been crap, as it drops after a while and I need to restart it every so often. So I never tether with it Wireless for that reason. However the USB tethering has always been FLAWLESS. Never had a problem, doesnt drop connection etc. Just recentlly it wont allow me to connect via USB anymore. The 'USB tethering' under the Tethering and hotspot option is greyed out. So I can't check it anymore Also when i connect the USB to my PC, the phone charges etc , but it wont allow me to access the stuff of my phone via the computer. I have Kias installed on my machine (which I re installed a couple of times) I have tried 3 different USB Cables, they all work I have master factory resetted the phone on 2 occasions. I have tried on a different USB ports and different computers. I have tried using with / without USB debugging I am still facing the same problem Could anybody please shed some light on how to resolve this issue??
