I'm sure this is discussed already but I can't seem to find it so if someone can help me or point me in the right direction.
I have a VZW GS3 that I have rooted, unlocked the boot loader and flashed CWM recovery. I then made a nandroid.
The main reason I did this was because I wanted Jelly Bean, and since Verizon is the slowest, I didn't want to wait so I installed custom ROMs.
Now that Verizon has released JB, I want to go back to my nandroid and then use the OTA firmware update service to upgrade.
Am I missing anything along the way that's essential for this to work?
Will the updated software re-root and/or relock my bootloader?
Will this automatically update the Baseband from my current VRLG7 to whatever the new one is?
One other thing, Will I still have CWM recovery after this happens? or will it revert back to stock recovery? or do I need to manually do anything to the recovery?
You're doing this to ultimately stay stock? Do you intend on flashing roms again or no? If you did a nandroid just after ONLY rooting and unlocking bootloader then restore it. Here's a step by step:
1) boot into CWM, restore your rooted, stock nandroid
2) Download EZ recovery, flash stock recovery
3) Wait for OTA
The OTA will relock your bootloader and unroot your phone. The JB OTA will also update your modem, and everything else, to VRBLK3.
One other thing, Will I still have CWM recovery after this happens? or will it revert back to stock recovery? or do I need to manually do anything to the recovery?

No, you will lose CWM if you do what I detail above. The OTA will fail if you still have CWM installed.

For the time being I intend on remaining stock, but I still want to root. Maybe once CM10.1 becomes stable, I'll go back to it, as of now I've had too many bugs with 10 nightlys and stable and 10.1 nightlys.

Nah I was just verifying to see if you modified any system settings or apps while on ICS TW. You should be in the clear as long as you reset CWM to stock recovery if all you did was root, unlock, then perform a nandroid.

before I restore the nandroid in CWM, do I need to do any wiping? cache, dalvik or full wipe?

No you do not, the nan will overwrite everything anyways. If you feel better then factory reset and clear caches, but it's not necessary.

I followed the instructions above and I'm back on my rooted TW.
When i try and update i get the following message:
Service Unavailable
To check for system updates, go to Settings > About device when service is available
What's wrong, how do i fix that?
searched around on google and a lot of people had the same warning error, multiple solutions were offered but none of them worked.
in the end, I ended up installing from odin completely stock unrooted, locked bootloader etc 4.0.4 (as f i want to return my phone to verizon) and once i did that it automatically updated to 4.1.1

I rooted my S3. I have not unlocked it.
I would like to backup the android operating system, the apps, and the data before I allow the recent OTA update.
Based on my research, I believe I can use titanium to backup everything except the operating system. How do I backup the operating system?
I tried the Volume Up/Power/Home Button restart. It gives me the option to restore but not to backup.
What am I missing??

Thank you for the speedy reply. I did a quick search and found quite a bit written on installing a custom recovery including on the S3.
It appears that I can only back up to a custom ROM such as ClockworkMod Recovery or TWRP Recovery and not the base ROM as it is on the phone now. Is that correct?
I have ROM manager on the phone so I expect the ClockworkMod Recovery would be the way to go.
Nope, CWM and TWRP are custom recoveries. You'll have to install one of those in order to backup. Go onto the app store and search for EZ Recovery. Use that app to install the recoveries(it's the easiest way for someone new). Then you just boot into your recovery and do a backup of your current setup.
Download EZ Recovery and flash CWM then boot into recovery and choose the backup option.

Custom recovery will backup stock rom. You will not be able to install any OTA until untill you Odin back to stock.
Thank you for the replies.
I guess I should have included in the initial post that all I have done is root the phone......I think.
I never unlocked the phone with Ez-Unlocker
I never used Rom-Manager either.
I did install SD Speed Increase and increased the SD cache size from 128kb to 1024 kb.
Thats it.
Does this information change the previous recommendations?
No, just install EZ Recovery and follow the directions listed in one of the guides in the stickies.

Yes, if you have a custom recovery you cannot accept an OTA. The install will fail. You will have to Odin back to stock in order to take the OTA.

Thank you for the input.
There is a lot of information on this topic but its not easy to determine which of it applies to my situation. I feel pretty good about being able to Odin back to stock but I'm not sure I want to take the risk of doing that (probably not much risk) just to get the latest update.
I expect the best thing for me to do is decide to either 1) go ahead and install CM10 (I think that's the one I would want) or 2) go back to stock and stick with the Verizon software. I'd like to get Jelly Bean now, but I'm not sure its worth the risk. We'll see.
Thanks again!
If u use ez recovery and flash back the stock recovery u can then accept the ota just fine. As long as u haven't messed with any system files you are good. Then just re root it once ota is done.

I have installed EZRecovery and it seems pretty straightforward. I'm still trying to decide if I want to go for a Jelly Bean ROM now or just wait.
I'll just keep reading until I'm comfortable that first, Jelly Bean will give me improvements worth the risk, and second, I won't brick the phone.
I have been fooling with computers since the 70s but Android is somewhat different and it will take a while to learn something about the architecture.

If new I would flash an ICS rom first and get you a stable daily driver setup and backed up. Regardless of what you read all JB builds are buggy to an extent since they are all ports. The advantage of Android is as long as you have a stable Nandroid you can experiment with more advanced ports. Backup IEMI also and be careful jumping back and forth between AOSP and TW based roms. This is where the most problems come up. From what I've seen if flashed AOSP base it is best to Odin back to stock before going back to Touchwiz.

Or Twrp
I prefer twrp as it will allow you to name the backup from within recovery as well as some things cwm doesnt do.
My nandroid backup was made after rooting, so after a restore from cwm (I was on jb deodexed) I was still rooted. I flashed a stock image from sammobile with Odin from PC and I lost root (that was my intention). All my apps and data are still here, did not lost anything. No wipe no cache clear nothing else. Binary count 0.
I want to be sure that when jb ota is released I'll be able to install it from the device without any issues.
Do I have to do anything else? I read in some posts that I have to flash the stock recovery, in others that the stock recovery is flashed within the stock firmware so I'm not really sure. Is there a way to verify?

try booting into recovery by holding down the power and volume up button at the same time until it starts to boot then release the power button and keep holding the volume up. This will boot into recovery and there you can tell if it's stock or CWM.
It's stock. After the nandroid restore from cwm when I wanted to reboot I was asked if I want to keep cwm or to restore stock, and I choose stock. I think I''ll do a wipe and whatever I can from the stock recovery. I'm just bored....

yeah and if all else fails when the update comes and you aren't able to get it then you can just factory reset and odin the stock firmware and then all should go smoothly.
I already did that

+1 it's worth the money to always have that as an option, just make sure you follow the directions (pretty simple)
It was the first thing I did after flashing the jb. As I stated in my first post, everything is ok on my device, I just wanted to be sure that I didn't miss something and that I'll be able to receive and use future OTA updates. I guess I'll have to wait to be sure, no point in making a tutorial on this yet.

I'm a tech savvy person in general. When it comes to rooting phones though, I just follow directions without fully understanding what it is that I'm doing. I understand what root access allows me to do, but I don't understand how I did it.
So, I have the Verizon Galaxy S3. In August, before there was an official way to flash roms, I followed instructions that had me root and install EZ-Recovery in order to boot into recovery mode and run a custom rom that way. I've been doing that ever since. Now that a rom can be flashed officially, I would like to do that, so I don't have to boot into recovery.
The problem is that I haven't been able to find instructions on how to undo booting into recovery. Is it as simple as just booting normally? or is there something special I need to do?
Also, I like the way my phone is set up, is there a way to back it up as is, and then reinstall it exactly how I have it. Does Titanium backup do that?
Sorry for what I assume are newbie questions. I had a hard time finding answers simply by searching. It is entirely possible I'm using the wrong keywords.
TLR, I'm booting a custom rom through recovery, but would like to use a custom rom properly
INFO: Using EZ-Recovery app and flashed CWM 6.0.1.0 running Bean's Custom Stock rom
Thanks for any info!
First to backup exactly how you are boot into recovery select backup and restore then select backup.
Second, I'm not sure what you mean by officially run a ROM the only way I know is to flash it in recovery. What ROM are you wanting to install?

Right now, my phone boots into a recovery mode menu and I have a bunch of options. I have to choose "reboot" in order to get to my phone/rom. I would like to be able to just turn on my phone and have it go into the rom.

Weird and it does that by just holding the power button? Never heard of that, maybe some one a little smarter then me can answer that.y answer would be to Odin to stock then reroot, unlock, etc and flash the ROM again and do an advanced restore of just your data (assuming you flash beans again)

Is it possible to do a factory reset and start from scratch that way?
If I'm reading this correctly he's still using flash method before the boot loader was unlocked. Id say the best way of going about this is to back up the ROM you're running reset the phone to stock reroot/unlock the boot loader then flash your recovery of choice and restore your ROM. I hope this helps!!

Thank you so much for the link.!!! This was exactly what I needed.
I have Verizons S3. I recently rooted and unlocked the bootloader and have TWRP recovery. I was on 4.1 JB. I made a Nandroid Backup of System and Data. I then flashed the CM10.1 Monthly ROM, and all seemed to be working fine. However, I was having some issues with my app backups and the weird "emulated" directory structure. So I decided to go back to my Nandroid Backup and start over.
I went into TWRP, did a factory reset, cleared System Data, cache/dvalick cache, then I restored the Nandroid Backup (system and data). TWRP said it was successful and asked to reboot. When I did, the Samsung logo flashes, and then the screen stays black. I tried going back into recovery, but it won't let me. I can get to download though.
I think I'm going to have to use Odin to reflash a ROM as I can't get into recovery, right? But I'm also trying to understand what I did wrong. Did I forget a step? Did it have something to do with differences between 4.1 and 4.2? I'm new to this, and have searched the forums but can't find anything that answers my questions specifically. I appreciate the help.

You're supposed to backup "boot.img" as well. I'm pretty sure boot.img is the kernel which you failed to backup. The phone won't boot into your nandroid because the kernel wasn't restored as well. In TWRP: system, data, and boot are all supposed to be backed up simultaneously if you want to restore the entire nandroid. Odin flash and make sure to do a proper nandroid with all three that I listed.

Ah, perhaps that "boot" checkbox wasn't check. =P So basically the CM10.1 boot.img is still there, but now the wrong ROM is there so it won't boot? Can I just flash the boot.img with Odin now, or will I need to do a full ROM flash?

No, when I do the button combo for recovery, the word "Samsung" flashes, then "Galaxy S3" logo, but after that nothing...just blank screen. I was on stock Verizon s3 before this, so I guess I need to put that kernel back on the phone? Is the kernel the same as the bootloader? Can I use the unlocked bootloader referenced in this post: http://forum.xda-developers.com/showthread.php?t=1974114?
So, I tried using Odin to flash back the stock JB 4.1.1 kernel, which should have matched my Nandroid backup, but then I got an unlocked padlock on my splash screen and then the yellow triangle. blah. so i flashed a stock no wipe rom and that got me back into touchwiz, but I cant get into recovery no matter what i do. And I still have the padlock. I think I may need to do a stock full wipe rom?

I get the VRALEC bootchain fine, phone reboots and all seems well. I got to flash TWRP 2.4, do a batter pull, and when I try to boot into recovery mode suddenly there is the Samsung splash screen with an unlocked padlock on it. Then the screen goes black and doesn't go into recovery. When I release the buttons, the phone then boots into the OS. I can still get to the download mode, but for some reason I can't get into a custom recovery. Any help on this? Please?

You can go directly to CM10.1, no need to flash anything in particular beforehand. I believe the only requirement is an unlocked bootloader.
Make sure to do a nandroid backup of your existing setup first. You should also read the thread on backing up your IMEI.
