You can downgrade via downloading the Stock 4.3 files from the SuperTool site by tom and flash that via fastboot. But be careful you can brick the tablet.

If you have OTA'd past 4.3 its just a simple download the images from toms server for 4.3 and fastboot flash them.

You can get the stock 4.3 images from : http://rootjunkysdl.com/?device=Tegr...%20Stock%204.3.

These files here is infact CWM/TWRP flashable zips so its just a case of unlocking the bootloader and flashing either CWM or TWRP then placing the stock 4.3 rom zip onto a SDCard and flashing it.

But before you flash the zip make totally sure you wipe the following partitions


Boot
System
Cache
UserData

This will downgrade you back to 4.3

Does this mean you have to unlock your bootloader?

I don't know if it apply to our device but it mean (on the readings) that KitKat suffer of a serious bug : The OS doesn't let some apps to go to deep sleep and the Wakelock are terrible.

That point and some others (more personnal) make me think to revert to 4.3
