I hit the forget key I was trying to hook up my Bluetooth keyboard now I can't

You have to go to bluetooth settings, forget the device, then make sure the keyboards off when you forget it, then turn the keyboard on and reconnect. I have to do it all the time with my Xbox controller.

You can try the following steps to find an operating system for your NuVision TM785M3 tablet:

1. Visit the NuVision website and check if they have any firmware updates or operating system downloads available for your specific tablet model.
2. Search online for the specific operating system version that your tablet was originally shipped with. For example, if your tablet was originally shipped with Android 6.0, search for "Android 6.0 firmware for NuVision TM785M3."
3. Be aware that downloading firmware from unofficial sources can be risky, it can cause further issues on your tablet. Make sure to download the firmware from a reputable source.
4. Once you've downloaded the firmware, you can try to flash it to your tablet using a firmware flashing tool such as Odin for Samsung devices or SP Flash Tool for MediaTek devices.
5. If you're not comfortable with flashing firmware, you can also contact NuVision technical support for assistance.

It's important to note that, if you're not comfortable with this process or if you don't know what you're doing, it's best to contact a professional technician or Nuvision technical support to help you with this process.

no idea you tell me

I had the same issue, and i resolved it by:

1. Typing the code '0000' + Enter on the tablet screen, making the tablet check
2. Hitting the same code '0000' (and maybe Enter, don't remember) on the keyboard right after.

..then the tablet paired the keyboard correctly. Good luck!
