Nebula 215 tablet will not progress past boot up screen
Hello, I have a Nebula 215 tablet that came with StarOS and a dedicated app. The tablet tried to update (either a system update or an app update, I cannot remember which) and now it won't load the app. It just freezes on the boot up screen. I cannot access the StartOS app either.
I can restart the tablet and hold the power and volume + button to get to a recovery mode screen, but none of the options have "recovered" the tablet.
Any help would be very much appreciated.
