If you have a rooted Galaxy S3 from Sprint, be careful, no scratch that, don’t do the new update to Kit Kat 4.4.2. Key word being ROOTED. If you have a rooted phone you understand what I am talking about here. But the way the update is set up, and Samsung’s KNOX app there is not a good way to root at the moment. It should not be long before there is though. The update just came out in the last few days.
Myself, I am getting ready to go back to the states, so I updated my phone just to make sure it is good, and Bam, there went my root, and not a fix for it. I have tried every possible route…………………. Now I just have to wait for a good fix.
Update: May 1, 2014
We got word of an imminent update yesterday, and it’s here today! Our 2012 flagships should be seeing over the air updates starting today, and the Android 4.4 build has been officially confirmed by Sprint. While a staged rollout will eventually hit your stock, unrooted device, you can force the issue by checking Settings -> More -> About device -> Software update.
Alternatively, the update has been pulled by CNexus over at XDA and can be manually applied. This is the pure, unmodified build, and applying it means a new, KNOX-ridden bootloader and the inability to root at the moment (this will also apply to accepting the OTA). And again, you must be on the latest, MK3 stock build, and take the risk of losing root for good.
