Last month, the official Android 4.2.2 update for the Samsung Galaxy Note 8.0 N5110 was leaked and few days back, folks at mini tablet leaked out the ROM for the N5100 Note 8.0 as well. However, many people, including me, have noticed faster battery drain since I have installed this update. S-Pen users will also notice a drop in accuracy compared to the Android 4.1.2 ROM. So, here are the steps if you wish to downgrade Galaxy Note 8.0 from 4.2.2 to 4.1.2.
I have successfully downgraded mine using the below given steps and Samsung Kies is also able to recognize it just fine.
