Samsung may take a while to release Android 5 Lollipop for the Galaxy Note 10.1 2014 LTE version but the folks at XDA have released a ROM that brings all the lollipop features and build to it. To install it, you must have TWRP on Note 10.1 2014 and then reboot into recovery. Go into wipe menu. Select "Advanced Wipe". Check Dalvik Cache, System, Cache and Data.
Then go into install Flash aosp-2015XXXX-lt03lte.zip, followed by GAPPS.zip and then SuperSU.zip to get root. Reboot and copy SuperSu and Gapps zip to /sdcard/OpenDelta/FlashAfterUpdate so that they are automatically applied after OTA update. In case Internal Storage not shown, type the following commands in AWB:
su
restorecon -FR /data/media/0
If you are looking for plain touch wiz free experience, then we suggest trying the Cyananogen Mod 12.1 on Note 10.1 2014 which is also great for general use.
