Want to upgrade my android os from 4.2.2 jelly bean to 4.3 jelly bean or kit kat. How can I do that? Rca doesn't have any advise or updates to any of that.

New, $175. Used. $70.

• Android 4.1.2 Jelly Bean OS, 1.2 GHz dual-core processor
• 8 GB Flash Memory, 1 GB RAM Memory
• Store photos, videos, music, and more with up to 64GB of memory available through a microSD slot and 50GB of free Dropbox storage
• Camera: 3MP rear-facing, 1.3MP front-facing

You might be able to upgrade the OS to KitKat 4.4 but are unlikely to be able to update it beyond. However, whatever gains you get in performance will pale next to sudden restrictions you find on SD card access. Android Central has users up in arms about SD card issues regarding the KitKat and Samsung. If the apps you like run under JellyBean, I'd not bother to update the OS. Other may choose to root the device.

Unless the manufacturer releases an update you would have to root the tablet to change the android version .

Hi
I would suggest that if it was advertised as coming with 4.4 KitKat and it has an earlier OS, then it is the subject of a false Trade description, and you need to take it back to where you bought and have it replaced with the one you thought you were buying ie with 4.4 KitKat and not 4.2 JellyBean. Bear in mind that (in the UK at least) your Sales Contract is with the Vendor, not the manufacturer, and it is therefore up to the vendor to put complaints right.
Hope this is helpful, if so would you please register that with Fixya
Cheers

I don't see have the steps you were given, (let battery get very low then get an SD card) is going to do anything to fix this. Without knowing the make and model there's not a lot to go on. What version is it running? Jelly Bean? Kit Kat?

Have you done a reset? Holding the power button in for 10 seconds until it shuts down completely? I'm not sure that doing a firmware upgrade is going to fix this. If you can get the tablet to run long enough you could try it, but if it freezes up in the middle of it, you could break your tablet.

You could download a JB rom for your nextbook 8 and flash it using live suit or do a factory reset by turning it off then hold down the vol up button then hold the power at the same time until you get recovery appear then you can do a factory reset.

can't do anything

Galaxy Tab is not running on OS 3.0 (Honeycomb), that is running on the Xoom only. Samsung would have to release an update for your Tab themselves. Google makes it available and only Samsung can make that decision.
