Answer 1

What you are to do is to access the AG Chrome Selfie's Recovery Mode and from there wipe the cache partition. Unfortunately, if the device will still not go past the start up screen in spite having cleared cache, then is may be necessary to hard reset it. Directions to both access the AG Chrome Selfie's Recovery Mode and to therein clear cache or wipe data are available on the link here http://satechhelp.co.za/1635/how-to-hard-reset-the-ag-chrome-selfie?show=1635#q1635
