[Q] Stuck on boot screen after attempted flash, no prior flashing experience :/ topic

I got bored of my now aging Samsung Galaxy tab 2 10.1 and decided to try and flash it to CM 10.1 . in hopes of a speed boost. I had never flashed before But these are the steeps i followed.

First i rooted device through Kingo Root aplication, No problems there.

Then i got Odin Mobile from the app store . I put these 3 files on my device .

E4GT-EL29-directbootCWM-v3.tar.md5
CM 10.1 ROM 4.2.2 JB
CM 10.1 Gapps zip

taken from here **cant post link as i am a new member**

Then in ODIN Mobile in the section that says kernal i loaded the first file and clicked flash firmware. But instead of rebooting into clock work recovery (which is what i think was meant to happen??) the tablet rebooted and then stalled on the Samsung logo, where it remained, even if i reboot . Samsung comes up on screen and it stays there.

i can reboot into what i think is recovery mode where i have some options i tried selecting "wipe data/factory reset" but the problem still persisted .

I have no idea how to proceed from here. Can someone please help me recover my tablet to its original state.

Thanks :)
