Guys, safariking came out with a rom for the sm-t210r based on the sm-t110. you can find it hereSo SamMobile just posted a new article about a new red Galaxy Tab 3 7.0 launch in US soon.
The news article explains that its launching with 4.2.2.
The last picture shows the model number SM-T210R.
I called the 1-800 Support number and the Galaxy Tab 3 7.0 SM-T210R will be updated to Kitkat the rep said, but could not give dates, and that was a week ago.
As with every other color refresh, the specs remain the same. You get a 7-inch 1024×600 display, 1.2GHz dual-core processor, 1GB RAM, 3-megapixel rear camera, 1.3-megapixel front camera, 8GB of internal memory and a microSD slot, Wi-Fi, HSPA, GPS, and Bluetooth connectivity, a 4,000mAh battery, and Android 4.1.2 Jelly Bean, upgradeable to Android 4.2.2.
There seems to be a 4.2.2 for a really similar device already.
Either you wait for a flashable port, or try to flash the ROM as it is. I ll give it a go in a few minutes
