Samsung Galaxy Tab 3 stuck at Samsung boot logo after rooting it with Kingo root app I rooted my Samsung Galaxy Tab 3 via Laptop using Kingo root app. I did everything correct but my  tablet won't turn on now. It is stuck on the logo screen. It won't load past the logo screen. I took it to a repair shop, and they cannot fix it. 

Can my tablet be fixed? What should I do to fix it? Would I have to buy a new device now?
Do you have recovery on it? Example: Clockworkmod recovery?
If answer is yes, try booting to recovery with key combination: Volume down+power+home and after 2 seconds keep holding volume down+power but stop pushing home.
You should download a custom rom designed for your phone, which is a zip file. Then on the recovery install from SD (must have SD card) and pick the zip file.

EDIT:

I had the same issue than you, service center couldn't help. Lastly I took it to the electric shop I bought it from, they helped.
