A friend has a broken Android tablet that we're trying to recover his Gmail address from. The tablet is an Elipsis 7 and is not rooted. We tried loading ADB to recover the information, but that failed. We have the tablet connected to a Windows PC, and see folders, but can't find Gmail. Some folders, like Applications, are seen, but when selected, they're empty. My friend just needs the Gmail address, so that he can change his password and open some files on his Android phone. Any suggestions?
