Question [Q] SPH-L900: CM10.1.3 CWM recovery over 4.4.2 stock

Hello guys!

There's a problem here.

I have Sprint Galaxy Note II SPH-L900. What I did:
1. Flashed stock 4.4.2 via Odin over stock 4.3.
2. Rooted via Odin.
3. Installed CWM via ROM Manager.
4. Flashed CM10.1.3-L900 (based on 4.2.2) + appropriate PA GApps via CWM. I don't like CM11 after 10.1.

Device hangs on boot splash (rotating ring), turns endless. Where's my problem? Is it correct to flash via CWM lower Android FW than previously flashed via Odin/Kies higher one?

And one more question. Is it possible to recover via CWM Stock 4.1.2 over flashed stock 4.4.2?

The common reason L900 is American Carrier version of Note 2. Since 4.3 stock TouchWiz looks most in English. This is my old age retired buddy's device. He doesn't read English and needs Ukrainian/Russian interface translation. That's why I advised him CM.

Thank you.

UPD. Solved. The problem was I didn't do wipe after flashing the CM10.1.x fw. Now works well.
