Nexus 7's MTP does not connect in mass storage mode anymore I've had a Nexus 7 for a year now and since the day I've got it, I could easily connect it to my PC and transfer file to/from it in MTP mode. But some weeks ago I tried installing Ubuntu on it and since I failed, I downloaded and reinstalled Android on it. But ever since, it is not recognized as a mass storage on my PC!

Does anyone know how I can fix this?
I've occasionally seen a new (or factory reset) N7 refuse to appear on a PC until you change the storage mode to camera then back to MTP. From memory (I don't have my N7 to hand) go to Settings, Storage, tap the three dot menu and there is an option to change the storage mode there.
