I had a similar problem. Trying out a tablet and used my Gmail account. I didn't want to delete the actual email account and the only way I found to remove it from the tablet was to restore it to factory settings. Trouble was it restored to Chinese but, luckily, I had two of these tablets so I could follow the path to change languages from the other tablet.

Yes but didn't have a lot installed. Went to settings, backup and reset, and factory data reset. It changed to Chinese, as I said, and would have had trouble finding Language and input, under 'Personal' and change language if I didn't have another one, so beware.

I couldn't connect the Android tablet to the PC at the time. Too late because Father C** didn't leave me enough time to play around.

What problems do you envisage by restoring to factory reset? It's brand new after all. Apart from the language hiccup?

Still - your idea is worth a go.

Let us know if you're successful. Thanks.

If apps preinstalled then they will still be there as factory reset. Go through setting, take photos with a digital camera of all steps as it will help, to remind you, of where Language and input, under 'Personal' and change language links are. Titles the same in Chinese (different characters) and the links are still the same place but you will need a reference so use a camera first to go through the steps. Make sure images are readable before you attempt a restore.

Go through the steps first. Fortunately once you get to the 'change language' the list is in English.
