Default Can't Install custom recovery on P5100 :(

Hi all I have P5100 and having issues installing custom recover.

I used both odin 3.07/3.09

Tried both CWM and Philz. I flash recovery on Samsung phones all the time so I am pretty sure my procedure is rock solid.

After flashing with Odin it shows Reset, device reboots. After full reboot I shut off then press Power + L Rocker button. It does a quick "Installing blah blah" errors out I see green droid with red sign then it goes to stock recover. This happens in a matter of 2 secs. (First time it was so fast I thought it went straight to stock recovery)

Now I did that a few times... My flash counter is at 6 right now and still can't reboot into custom recovery.

If anyone could point me in the right direction or possibly another way to flash recovery besides odin. Thanks !


Edit: Tablet is currently on stock 4.2.2
Edit 2: Tried all USB ports on my laptop. Tried different cable. Tried different PC. Still won't start custom recovery
Edit 3: [SOLVED] Rooted the damn thing again using odin, reboot, flashed custom. Now done.
