OTA to 4.3, can i install JediX20? topic

Hi all,

I just got a Note 2 T889 with OTA updated to 4.3. I rooted and installed JediMasterX2. Running well for past 3 days. Can I flash JediX20 if I wanted to or not possible on boot loader T889UVUCMK7?

Since I don't have warranty not issue with Knox.

Reason is that I remember getting exceptional battery life on 4.1.2 on my previous Note 2.

Thanks in advance.
