Sorry if the question has been asked before but I just got my s3 on Monday and rooted it the other day. My question is if I want to check for updates is there away I can do a temp unroot to check? I know when I had a different android if it was rooted I couldn't use system update because the root took that out. Wondering if its the same for this phone as well.

There is a app called OTA RootKepper that is designed to allow you to take an OTA update and preserve root. I have not used it but only hear good things about it.
I used this method to get the LI3 update on my rootes stock LG8.
The newer versions of superuser and supersu have this built in as well
Or you could just flash a rom based on the update, or just the kernel, or just the modem/baseband. No need to unroot just to download an OTA.

I ended up buying OTA Rootkeeper to save root in order to update, worked great.
So even if my phone is rooted i will still be able to get OTA update notification?

Yes. Even if you are rooted your phone may check for and download the ota update (unless you disable the checking out are running a Rom that has removed the checking).

With SuperSU, even unchecking the enable super user box I still get the message that my device has been modified and so I can't get updates.

We should all be getting the official Jelly Bean update in the next few weeks from what I've heard. My main question is my GS3 right now is rooted, stock rom, with a custom kernel.
When the official JB comes out can I just update right away or do I have to put the original kernel back on the phone before doing so? Or will the update install a completely new kernel with the JB?
Thanks guys.
Any updates will install Rom kernel radio and recovery

I actually never updated via kies but i believe stock rooted should be fine to update.. correct me if in wrong guys.

Yes you can update with root, but unless you use Mobile Odin, voodoo ota rootkeeper, or cwm you will lose root.

Okay thanks for the tips on keeping root. But as I said right now I'm running the Trinity kernel. With the new JB update via OTA or Kies will the kernel also be replaced? Don't want the Trinity kernel on there as it probably won't be compatible with the new JB.
Yes they will be replaced. Everything is written over.. except data, which i recommend to wipe anyways lol

Actually it will probably fail. The ota requires you to be FULL stock. This includes kernel.

Hmm i just thought about that.. how is he running a custom kernel? Must be running a custom recovery and that will fail for sure. Not sure about custom kernel though.

Well, there are a few ways you can get a custom kernel without a custom recovery. Its rare to do so though.
But yeah if the kernrl isnt also matching stock itll surely fail

With my Nexus S when we received the JB ota update I was on a stock rom, rooted with a custom kernel and different radio and the update failed. If I resume..
Rooted with stock rom, custom kernel, different radio = Failed ota
Rooted with stock rom, stock kernel stock radio = Working ota
But I'm no expert, could be different with GS3

Cool, never did any official updates after all this time with android. Good to know lol... but probably never going to officially update anyways. Rather wait for someone to build a rom off it lol

Pretty sure I lost my original backup I created with Root, Stock Rom, Stock Kernel. Does anyone have a link to the STOCK UVALH2 kernel?
You can just use mrRobinson's Stock Rooted and then use the OTA Rootkeeper to temp unroot, take the OTA and then restore root.
When my Transformer went through several ICS OTAs, I learned a bit about how updates work. They first do a system check, meaning they look for Stock ROM, Stock Kernel, Stock Recovery (all of which can be found on here), but they also look for specific /system/apps (bloat). If there is something missing then the OTA will fail.
If you flash back to full stock, make sure you don't delete anything from /system or disable it in Settings. I ususally freeze it in TiB and then when taking the OTA, I just defrost them.
If you want to manually unRoot just use terminal and run the below.
Code:
su
rm -r /system/app/Superuser.apk
rm -r /system/xbin/busybox
rm -r /system/bin/su
reboot
You may need to take su out of xbin if it is in there too. Check before running these codes to see which or both it lies (/bin and*or /xbin)
Got update ...

Are you currently on build UVALEM? If so would you be willing to make a copy of the update.zip for me? It should be located either in /cache/fota or /data/fota
Honestly the easiest (and in my opinion the best) way to get to the latest official build UVALH2 and keep root is to flash MrRobinsons root66 version with odin or mobile odin.
Though if you just want to use the ota then you first must be full stock, no mods no removed bloat, etc. Then get voodoo ota rootkeeper and preserve root, reboot to stock recovery and flash the ota. Then reboot and restore root.
Alternatively, you can flash with mobile odin pro and itll inject root during the process. (Dont do this if you have modded build.prop for wallet). You dont need to meet the stock requirements this way.

Run.. your phone may explode at any moment.
Worse case you will have to re root the phone. Not a biggy tho.. Rooting this thing is exceptionally easy.

That's your JB OTA. You can accept and it will install (if you have a stock recovery), or fail (if a custom recovery). If on stock recovery, you will loose root, but can just root again. If on custom recovery, nothing will happen, but you'll continue to receive the notification until you either have a build.prop that matches the latest base, or flash a ROM based on the latest base. Which is my recommendation. Browse the options available in the Android Development thread, choose one of the LJ7 ROMs, flash, and be happy!
ROM - Odexed Blue JB "Holy Grail" LJ7
Baseband - LJ7
Kernel - Stock LJ7

Hey guys, sorry if this is a noob question but I never had to do this with a stock ROM on a device lol. I am currently on the stock ROM with root and know that my device can no longer get OTAs. I was wondering if I could be able to temporarily unroot and be able to receive an update without having to revert to my old backup? Thanks!
More info: I did not root with motochopper, I flashed a root zip.
If you update to the new ota your will lose the ability to root again. There is a kernel update that isn't Mentioned

Not true, you can just flash a older kernel that has the vulnerability. Until the android version is updated all the previous kernels will still work.

So you're saying that I can update via kies, flash the MDB kernel via odin, and regain root while being on the new build MDL?
