Hi guys, I'm glad I came across this thread before I did something I would regret. I am currently running RocketTab 3.1, 4.1.2. I believe that is the latest version of it. I was reading that Kit Kat has recently become available for the Galaxy Tab 3 and I tried to update it OTA but it gave an error that said I modified something and was unable to get it. So I manually downloaded T217SVPUBNE7 and I was about to install it. I'm glad I stopped and took the time to read that it was only for the SM-T217S and I have the SM-T210 as was mentioned above.
Being rooted, I don't think it would be a good idea to take the OTA when it becomes available. Am I right, just wait until it's actually released for the SM-T210 and wait for a root method?
