Resent I install new leeked kitkat version
And now I want to install back original jellybean version in my tab
So how can I downgrad my tab from kitkat to jellybean
Bro u must ask questions in question answer forums in this way u can get help more easily
lets come to the problem u cant use odin on pc becuase your bootloader is now locked so i suggest that u use mobile odin to flash it
mobile odin require your note 10.1 to be rooted to you should root it before proceeding
u can download proper firmware of your note 10.1 from sam mobile web site just down load it copy your rom in external sd card select appropriate options from mobile odin app and then flash it after flash is completed just open recovery by pressing power + up button while the tablet is booting and clear data and clear cache after that ur note will be downgraded to 4.1.2 and u will be good to go
backup ur data cuz this is going to clear everythig
