USB broken.. Can I root/flash recovery? topic

Hey all,

My USB broke i guess. I tried different cables and different computers, but nothing recognizes the device at all (not anything in device manager).

My TF700 is unlocked, so no warranty :( I want to flash a custom ROM, but my tablet isn't rooted and has stock ROM and recovery. Anything I can do or is my only option to get it fixed by asus? :(
