Folks at Sammobile have leaked Jelly Bean (N7000XXLS26) for Galaxy Note. Keep in mind that this is still a buggy release and is meant for internal testing. An xda member has enlisted the changes:
1. Clean installation (wipe your all data except gallery & video)
2. Screen more responsive and quick
3. No Air view
4. No S-Voice
5. Auto capital letter error in message
6. No root
7. Battery not so good
8. Performance is good
8. Rest is same as RR rom
Sammobile says that the firmware is not exactly super fast, even though project butter was implemented in it. But, then since it is not official, we cannot complain much. Still interested? Grab a copy of ODIN; put the Note in download mode (same as Note 2’s procedure) and flash it (select file in PDA and flash N7000XXLS2.tar.md5) by hitting the start button. A word of caution – flash it over the latest, official firmware. [sammobile]
