I have a problem with my Nexus 7 (self inflicted) and the bottom line is that I need to retrieve some files (.txt) that are on the device but I can't get it to boot. I basically rooted the device and everything was running perfectly until I accidentally clicked to update the OS. Now when I try to switch the device on it just goes to the new 4 coloured globes loading screen and stays there indefinitely. Unfortunately when I plug the device into my computer it isn't recognised so I can't access the files on the device. I am able to get the device into recovery mode so I can perform a factory reset but before I do that I really need to get some files off the device that I was working on. Is there ANY way that I am able to access the files on the device to retrieve them in its current state? I don't seem to be having any luck in getting the device to show up on the computer even in recovery mode. If you need any additional info don't hesitate to ask.
