USB connection broken, tried debugging I have a Galaxy S2 that refuses to be picked up by any computer. I tried different operating systems, I tried a different USB cable, I tried debugging mode. The phone still charges fine through the port but maybe the data section of it is broken. Before I take it in for repair I just want to hear if there's anything else that can be tried? I'm thinking of doing a hard reset but don't want to lose any data. Any advice would be appreciated.
As my old electronics teacher told me, check the power then the physical connections before doing anything else....I have spent 3 hours trying various fixes on my phone, all to no avail. was working fine, then around the time of the most recent update it failed to connect (Hence software fixes searched for first). I finally thought I would try to clean the usb port on the phone...(compressed air had not worked) I had some copper soldering wick and a very small screwdriver, turned the phone off (Removing battery would probably be a safer bet in hindsight as well) and rubbed the copper mesh around every surface inside the port...works perfectly. Possibly many of the issues with using a different cable could be fixed the same way.
