Alot of people with rooted phones has had the update failed. Look on XDA
I've been reading that some people were able to successfully restore root access using Voodoo OTA RootKeeper. This is important for me because I was planning on rooting my Note 2 soon (only so that I'll be able to add APN information in order to get data when using a GSM SIM card). I guess I need to go ahead and root and then back it up.
A patch for the exploit makes the most sense though, given the size, timing, updated kernal, and the fact that it breaks to ability to achieve one-click root with the Exynos exploit method.
The update apparently has a new bootloader in it too, so it might lock the device up for those who have or who might want to have an unlocked bootloader.
I haven't seen any confirmation that the new bootloader does indeed prevent things from being unlocked with the previous methods, but until it's shown to definitely go one way or the other, it's best to proceed with caution if anyone has any potential inclination to unlock or root the phone in the near future.
"security patch" :icon_eek:
I updated and I might be crazy, but my phone seems to be running slower...like a lot slower. Page transitions are jittery and the response time is just not good.
