Help, I was reading about downloading firmware in order to get Google play to download amazon.  I went to arctools app, downloaded it, went to firmware, started the download and got scared about ruining my tablet.  I thought I stopped the download but I guess I didn't.  Now when I try to use my tablet, I get an 'install or cancel' new firmware.  AND my tablet is not responding at all, it is frozen.  I have turned it off and on multiple times, it starts to calibrate then goes back to the firmware message.  Is there anyway to get rid of that and reboot my tablet back to factory settings.  Or have I ruined my tablet?  I would appreciate any help.  I tried the reset button, but it hasn't worked to get around that firmware download.  I don't want to lose all of the factory downloads.  Thanks for any help!!
