How to uninstall 4.1.2 and go back to 4.1.1?

[howie91]

Does anybody know how to go back from 4.1.2 to 4.1.1 the main reason for doing this is that i have lost my punctuation bar on my s3 keyboard and find it useful. Would a factory reset do it or not?

Don't bother doing a factory reset coz it don't work. My galaxy s3 downloaded the 4.1.2 update last night and since the my battery drains faster than Usain Bolt and I've lost the auto correct feature when using the keyboard. The factory reset just resets V4.1.2. I would like to go back to 4.1.1 but don't know how. Pls help

Same here with the battery drain. It's gone from 100% to 75% in an hour and a half and I'm not touching it! finally get Jelly Bean and it screws up my battery.
