Is it safe to downgrade from stock jelly bean to stock ICS?
There reason I'm asking is that I wasn't able to get the Jelly Bean OTA to work so I manually flashed the Jelly Bean OTA using Odin. The one I flashed came pre-rooted and pre-loaded with a custom recovery. I want to have a completely untouched stock version of Jelly Bean, something I haven't been able to find here or elsewhere (I would get this by doing an OTA update to Jelly Bean from the stock ICS rom that I flash).
I'm thinking that the reason that I couldn't get the OTA to flash (it gave me an update fail notification every time) was because I wasn't completely stock on the previous ICS version, even though I had unrooted, relocked the bootloader, thawed bloat, etc.
If anyone could answer the first question, and the others I've raised, that would be great.
(I know that it is probably OK, but I wanted to double check since it was a major no-no to downgrade when I had a Droid Razr Maxx).
Yes, you can safely downgrade in order to take the OTAs.
Yes, your past OTA attempt probably failed because you weren't fully stock in some way. There is an error log stored on your phone that you could have checked for the exact cause. As a general note, OTAs require you to be on stock recovery, but not necessarily Unrooted.
You mention that you are unable to find a stock image file for the JellyBean update. This file is readily available here at XDA, and can be downloaded from the following thread:

Performing only Step 1 from that thread would leave you with a fully stock, unrooted, locked bootloader JellyBean ROM.

I was planning to flash Jelly but decided that I'm happy with ICS and liam wilng to wait for the OTA update. What's the process for preparing for the OTA update?
The method I used to root the phone was I believe the easy one click root debugfs-root. I used EZ-Unlock to unlock the bootloader. I also installed EZ-Recovery. Thanks.
Flash back to stock before applying any ota from Verizon

Give this a try. I just posted this in the development section. Original OTA updates modified to work on rooted, custom recovery, bootloader unlocked devices with Google Wallet and NFC libraries installed.

(edit) If you don't have the latest SW for the S3 yet you can apply those OTA updates on your rooted, custom recovery, etc. device. When the Jelly Bean OTA comes down I'll be sure to make a rooted, custom recovery-friendly version of that OTA as well.
Hi am having a problem after going back to telstra stock after being on rohans JB build 3. It was really bad at connecting on LTE so I wanted to go back to stock where I have less problems. So now the 4.0.4 OTA update is available which fixes the one of the main reasons I found a ROM, that stupid settings bar.
However when I reboot to install the OTA it just boots into TWRP (v 2.2.2). I cant manually apply update from within recovery. It just gives an error. If I reboot from recovery nothing is applied.
Android v 4.0.3, software version 1.89.841.9
Do I have to get rid off TWRP or find a RUU and and apply that image? Was there some boot locking thing I need to do through abd to get the OTA to work?

Pretty sure you have to relock your bootloader and run an RUU to get your phone to true stock. Then OTA. Although, if the RUU was based off 4.0.4 you wouldn't have to OTA. You can always re-ulock your phone after an RUU as long as you have your unlock token and/or super CID.
Did you just flash a stock ROM?
Also, pretty sure there are 4.0.4 stock ROMs out there that you could flash so you wouldn't have to relock your phone.

Thanks I restored a backup I made before flashing the ROM. Might try and find another ROM to see how 4G goes.
Fixing a connectivity issue on one custom ROM is not a good reason to go stock. I think the OTA needs stock recovery, so that is why you are getting stuck at recovery. Even if it works, you lose root. Its a step backwards, so why would you want to do that?
Just flash a ROM based on 4.0.4 from Development. You can pick a custom ROM, or a stock rooted one (safe to flash from TWRP), if you want stock.
If you are rooted, don't install a OTA or run RUU (unless you are trying to fix a soft brick). Good rule for any Android device.
Hi all: There seem to be 2 Guides in the developer section for rooting/S3 with OTA jelly bean, both by same developer. They are titled as below:
Root, Custom Recovery, and Unlocked Bootloader for Jelly Bean OTA
Stock Jelly Bean Factory Images with Root, Custom Recovery, Unlocked Bootloader and No Data Wipe
I just want to root/unlock my stock phone, leaving data intact. The two guides are different. One is updated 12/12, the other 12/25. One has a single download for recovery + stock image, other they are separate. Not sure which one to use. Thanks.

The second one is for those who want to flash rooted stock ROM via Odin. Either one will do.

Got it. Thanks. Did the first one - worked like a charm
I have a stock rooted 4.0.4. I need to get 4.1.2 because I am having bluetooth problems with my new Ford Fusion with My Ford Touch. When I try to update, I always get "No new software update available". I am willing to do the update manually, but I have yet to find just the update its self. Also I do not want to lose my data. How can I find the update and install it without redoing my whole phone?

You need to go to 4.1.1 first since you are still on ICS. There should be an image in the guide that you can flash with odin that will upgrade you without erasing your internal sd.
From there you can take or manually flash the ota to get to 4.1.2

THANK YOU! Exactly what I needed
Thank you guys in advance for your help but I just had a few questions. I am running 4.4.2 currently with the stock rom rooted and unlocked bootloader. I have however issued a few Mods such as extreme power saving and built in tether. Can I just load the 4.4.4 firmware and radios, switch back to stock recovery and take the OTA to 4.4.4 without having to wipe anything or since I have used some mods do I now have to wipe my device and put everything back after getting the 4.4.4 update. The reason I ask is I like having the stock features while just using google now launcher on top of sense. Also would any of you have a recommendation on a ROM to achieve this same thing so I dont have to go through this everytime I want to take the newest OTA if it is not possible to take without wiping.

Flash the ruu here. That will get you to 4.4.3 the easy way and make you 100% stock so you can take the ruu. Then flash twrp and flash su or the rooted Rom of your choosing.
The RUU is one way to go, although I would never update via OTA...
Another would be to flash the firmware and radios from here:
http://forum.xda-developers.com/showthread.php?t=2723159
And then Scott's rooted stock rom from here:
http://forum.xda-developers.com/showthread.php?t=2914922
He usually has them up a few hours after a new OTA has been released. Even better - try his stock, debloated CleanROM once it's out.
This way you can keep your recovery. You can even try to just flash the 4.4.4 firmware and radios and see if it runs your current 4.2 ROM ok. But I would not update the rom from version to version without a wipe.
The setup is the price to pay for getting a new and hopefully better Android version.
