How do you uninstal 4.3 update

Since Update:

1. My phone keeps redownloading every email attachement over and over again.  YES I've checked the download attachements is not selected. Etc. Etc.

2. My phone no longer accepts my microsd even though I can view over the Motorobo software tool, it works on other phones and I even reformatted it.

They aren't re-downloading, you're just getting the notification of the old download over and over.   You can find the solution on this post.  http://forums.att.com/t5/Android-Discussion-and-Support/What-are-these-after-upgrade-S3-to-Android-4-3/m-p/3859413#M48663 

"Go to the downloads app and clear everything out. If that doesn't work, go to settings > more  > application manager > swipe over to all > scroll down to download manager and clear the cache."

This does not delete your downloads, it just deletes the notifications of your old downloads.  Once you clear your download notification history, you should't have the issue anymore.  Do note that the Download app has a couple of tabs for different kinds of downloads; you'll need to clear each list under each tab.

I find it troubling that the original poster's question was not answered and yet the community accepted solution is not helping solve the problem.

While the answer may be "its not possible", it's not that clear with the word "typical".

Is there an exception so it is possible?

How does redpoint73's response help the person with the problem? Don't solutions solve problems?

To the best of my knowledge, the only way to uninstall a software update is to root your phone, which I do not condone by any means. Rooting can be fairly risky if you don't know what you're doing. Be aware that rooting your device also voids any warranty that may remain on the device. 

Rooting is still not 100% guaranteed to work in regards to rolling back a software update. While I have never personally rooted nor hacked with any form of an electronic device, I have heard that it is a fairly challenging process as far as finding the necessary files and information to complete the process - if it can even still be done at all due to its lack of credibility. 

I know that Apple did not allow iOS users to downgrade from iOS 7 when it was first released unless they had previously saved a particular file to their computer within the first week or so that would allow the update to be revoked. I'm not sure if Android operates in the same way in regards to a certain time window to uninstall the update. 

In short, I believe it's possible, but it's not necessarily a piece of cake.

Hope this helps to clarify any uncertainty you may have. 

Unfortunately you CANNOT as of right now, according to XDA developers  root a samsung Galaxy running the 4.3 OS because of the KNOX security program running on Phone. You are basically screwed until Samsung and AT&T releases a Patch. I have been on the phone with them alot... they will not fix, replace, or do anything free. dont even try, they are horrible.

While my response did not address the battery drain issue (which can have a variety of causes, and therefore there is going to be no "silver bullet" solution - its also been discussed ad nauseum in other threads on this forum) it answered the question "how do I uninstall 4.3", which is that you can't.

I say "typically" and "stock devices" since it can't be done unless you have root.
