Code to unlock RCA voyager 3 tablet

Good evening to you
If I remember correctly I held in the home button and sleep button simultaneously for ca 30 seconds. enjoy your coffee, Kolbrun

Hook it up to your pc, back up all your staff and send in for repairs or order new screen if you can put one on your self, if not when you get another you'll have your back up. Good luck

There's a big difference between 'sign-on' and 'log in' screens. Which one did you mean?

We need to know what is doing exactly in order to get the proper help. But if it get stuck in the boot, or it's in a bootloop after a hard reset, then you should flash a new firmware. That should fix it without a doubt. If, and only if, it still have problems booting up, then you have what its call a hard brick, meaning that there is a problem with a hardware, probably the processor or any of the motherboard component.
