check in the development section under official firmwares post. there are official firmwares and instructions for odin. try to charge up battery as much as possible. a failed Odin flash could be a perma-brick. If you have Kies , I think there is an emergency software recovery option as well.
The KK5 is the original firmware that the p-6200 came with . If you install that, as soon as you run it, it should be giving you the notification that an update is available . There will be 2 incremental upgrades and you will end up with KL1.
Or you can directly download the KL1 .
Before venturing yourself into flashing the stock rom why don't you try a factory reset from the recovery menu :
Turn off the tablet
Press at the same time the power button and the volume up button
As soon as you see the galaxy logo release the power button but keep the volume up pressed until the recovery menu pop up
Select the factory reset option using the volume button and confirm with the power button
I am pretty sure that it will fix your problem
Let me know how it goes
