It will be an unpredictably long wait until one is available. The speed of these things becoming available seems roughly proportional (inversely) to the popularity/sales of the tablet.

It's too early to tell how popular this will be, but I certainly haven't heard anything in regards to sales figure. This is not something that gets the attention of something like an iPad or even a flagship android tablet (Note 8.0?)

This is one of the disadvantages of fragmentation in the Android ecosystem. Too many different devices for developers to keep up with, especially the more obscure ones. But at least the Tab 3 8.0 has a physical presence in big retailers like Best Buy and Staples.

Just as a wild guess I'm guessing there will be a root guide by early August.

 

Looks like my guess is spot on - it has been rooted*

*it still seems somewhat not finalized yet, ppl over there are still working out the kinks, but the prognosis for a stable root in the near future is good!

 

Hello Gam3r 4 Life. Once the XDA (or any other method) is finalized, it'll be published via link in the Tab 3 80 All Things Root Guide:

Galaxy Tab 3 8.0 - All Things Root - Android Forums right here in the 8 forum

along with all info about ROMs, etc as those things come along.

 

I know I'm late to this party, but just got my Tab 3 8.0 last week. This PC program worked like a champ:

Root Android phone, flash custom ROM and manage your Android devices, Rooting Freeware Download - Kingo

Just install on your PC, connect the Tab via USB, and it does the rest - IDs the device, installs appropriate files, roots and reboots the Tab. Couldn't be easier!
