I'm having a hard time looking for guides to revert back to full stock, right now I'm using the SnowJB rom but I want to revert back to full stock.

Trying to flash new roms but they want you back to stock and upgraded via OTA to JB. I had backed up my phone prior to Snow JB but after restoring stock ICS, I am told that the update is unavailable. Can it tell somehow that I had flashed a custom rom and is now blocking me from updating? Looking to try all those new 4.2 and 4.1 roms and they all want you to start from a stock updated phone.

First prerequisite is you will need to re-lock the bootloader to get the OTA update.
The weirdness, however, is that at least up till now, the OTA JB update will only work from the 11c version. Apparently for the past few months the 11c update was not presented by the update servers, because most of us who got our phones recently with 10o were never offered the upgrade; then on Easter they "turned on" the 11c" updates again. But then once JB was out, it seems they only made 20j available by default, so if you had 10o (not sure if this is the one you have or not), you were stuck and unable to get 20j. Some people have been reportedly re-offered 11c but I'm not sure if this means it's being made available again on a widespread basis. Seems kind of weird that the update server can only make one version available at a time, or that they couldn't make a universal update that would work starting with either version.
To get past this, you can call up at&t (or live chat with them) and ask them to push the 11c update to your phone. Then after installing that update, it should be offered the jb update automatically shortly thereafter. Or, use lgnpst with the full stock jb image.
There seems to be some other error with phones not being registered properly in at&t's update system and they are getting an error that at&t should be able to fix.
But to confuse you even more - I believe that someone has taken the essential parts (trustzone stuff) of the stock JB rom and made a mini-image you can flash with LGNPST instead of doing the full stock jb update, so it's a lot quicker if you're not aiming for full stock JB anyway. See this thread: http://forum.xda-developers.com/showthread.php?t=2229568
Once you have done either method once, you don't need to do it again.

Search on lgnpst or go to the #lg-optimus-g irc channel for a full guide.
Short version: install lgnpst on windows machine, download 11c tot, factory reset in recovery (jb and ICS aren't compatible), power off phone, enter download mode, start lgnpst on computer, select ls970.DLL and 11c.bin

I have lgnpst 1.1.3 ...it wont recognize my phone at all. I used freegee to unlock my bootloader so I'm rooted also. My HUGE problem is I can't flash any 4.2 ROMS because I'm not recognized on lgnpst and I cant finish installing the at&t update because my bootloader is unlocked...I'm not sure what to do at this point. I'm stuck with the older ROMS!! =/

[Q] Cannot Update to 4.1.2

I have 4.1.1 Jellybean on my phone, is unlocked, an had no trouble updating to 4.1.1 from ICS. Now that my phone shows "Updates Available", downloads them files( I think), but does not install and rather says "Your device has been modified. Software updates are not available". The new updates I have seen in my mate's phone are good, and as he told me he had no trouble updating to it unlike mine.
What is the problem and the best way to solve this issue?
Also I'd like to ask, if I used Odin to update it manually, will I be able to update my phone with later releases without having to use Odin again?

You answered your question yourself...modified = no ota update. Go back to stock unmodified or easier, download the new version from xda or sammobile and flash via odin

Well i don't know what you mean with "unlocked" . If you mean rooted then it's easy :fingers-crossed:. You might have rooted with CF-Root or Toolbox or whatever. And in that process you were forced to install Clockworkmod Recovery and that's the reason you can't get OTA. If you want to have a rooted phone and OTA all you have to do is. Root your phone, stay on stock rom and flash the stock recovery via odin. But this means you loose CWM Recovery and a lot of the fun part about a rooted phone is gone.

What part of "Unlocked" is confusing to you? It means the phone can run any sim card of any sim provider, thats what I meant, and no, the phone is not rooted or never even have tried rooting it... Never mind, I factory reset the phone and the update is done. Anyways kudos for your reply
Cheers!

[Q] Newest VZW Update VRAMC3

OK so here is the story and I was debating if this is the right place to post but I do feel it is more on the developing side. I originally rooted and unlocked my bootloader following Casuals method and everything was just fine. I had an option to sell the phone in preparation for buying the GS4 so I used the return to stock method posted in the forums to return my device completely to stock. After doing so everything was also fine. I received an update to LL4 and that went OK straight from Verizon but last night when the VRAMC3 update was pushed to my phone it soft bricked it. It ultimately was stock on the splash screen stating Samsung Note 2. After trying to ODIN back to stock with multiple FAILS I was able to get it back to the Root66 MR Robinson by using the pit file but every time I try to update and or root/unlock bootloader it soft bricks again. I am assuming that the update that was pushed updated my bootloader and as of now I am stuck till there is a new bootloader Jailbreak. If not I would love some instruction on how to get my phone rooted with an unlocked bootloader or a flashable ODIN file that will at least get me to the latest VRAMC3 fully stock ROM. Thank you for the HELP.
Next time read the stickies...when they say NOT to accept OTA updates, usually there is some meaning behind it.

I had the same problem. Flash the pit file with odin and wait for the phone to turn on. the problem is fixed to get the phone working. Then you can flash other stuff.
Thank you for the replies even though one was not helpful at all. I have flashed the root66 file with the pit and it does work but if I try to run the casual jailbreak or flash any other odin files it fails. My assumption is my bootloader got updated and has locked me out and I will just have to wait for a new boot loader exploit. Thanks

Is there a sticky or something definitive on the subject of rooted (via Casual) Verizon Note 2 users getting the OTA update and retaining root? I'm currently VRALL4, rooted via Casual, with SDM frozen to avoid the OTA update. But I'd rather not stay in this state indefinitely.

Once you are rooted via Casual there is no such thing as accepting Verizon's OTA if you want your phone to keep working. (This info can be found in 1 or 2 basic searches, which everyone should do first.)
If you want to get the 4.1.2 features there are 3 options that I know of: 1) flash a zip of the 4.1.2 update, 2) flash a full 4.1.2 stock rom, or 3) flash a custom rom that has 4.1.2 features in it. You can find all 3 options in the Original Development section of xda. Imnuts has implemented #1 but read the forum on the ins and outs. Beanstown106 has created #2. And Beanstown106's latest Jellybeans 16 is a custom rom that incorporates 4.1.2.

[Q] Can I flash back to 4.1.2 after using the 4.3 leak since I was rooted? on a i605

Good Morning everyone. I need to flash back to 4.1.2 to get my phone looked at. Is it possible to re-root after I get my phone back? I see people are having problems using casual and getting a partition 60 missing? or something on that order any help would be greatly appreciated.

When you say "flash back to 4.1.2", do you mean just flash a stock 4.1.2 ROM, or use ODIN to restore your phone to factory locked condition?
As long as the phone does not accept the 4.3 OTA then casual will still work. If the 4.3 OTA gets installed on your phone, then you will not be able to unlock the bootloader again. You can still achieve root access, but not unlock, which will prevent you from being able to install custom roms.
I just want to make sure I've got this right. I've done the VRUEMJ9 4.3 OTA update. If I flash back to the stock VRAMC3 4.1.2 build using ODIN, I still won't be able to unlock my bootloader?
If so, I wish I'd known this before I took the OTA update. On my old phone, I could just sbf to an older build and that took care of any problems. I thought that it would be the same with this phone, but I guess not. Frustrating.

That is the case, unfortunately. From the research I've done it would seem the bootloader on this device cannot be downgraded. The files we have available to flash via ODIN do not change the bootloader, they are not full images. And yes it is frustrating, several of my family members were not the happy with the 4.3 OTA and were ready to take the custom ROM plunge, too late.

What update are you on? There might be a mini update you have to do first before you can take the KK one. That or you'll want to run the RSDLite program to rewrite the software back to it to make sure any possible modifications that were done to the /system from rooting or the attempt are undone. They haven't released 4.4.2 for RSD yet, so will have to do the last official one and then factory reset (if it doesn't do it for you) then try the OTA update again.

There are 4 different 4.1.2 versions. If you are on an earlier one, this could cause this problem as well.

I am on 98.18.94.xt907.Verizon.en.US 4.1.2 Okay hmmm I will try that after work and see if I can fix it?!
The 2012 Droids (HD, Maxx HD, and M) have been very problematic in getting their respective KK updates to work. You basically have to be BONE STOCK in order for it to work. Best bets are to find the appropriate RSD Lite method as mentioned above and follow it EXACTLY, or to do a factory reset of your phone and let the update get pushed to you again.
Chances are the root did in fact work and some modification was done that is causing the update to not go through. Either that or the phone is still rooted and the OTA is refusing to install because of the root access.

New update that fixes connectivity, install while rooted?

I've had this pending on my phone for quite awhile, I haven't done it because I'm rooted. I decided one day to try it, my phone rebooted to TWRP and nothing happened. Which is exactly what I thought would happen. So I pulled the stock recovery from the stock rom and successfully flashed it. Tried the update again and I am getting a bit error from the stock recovery. The phone goes into "wtf just happened" mode and I have to do a battery pull and reboot. Which works fine. I don't really want to backup everything and re-root and reinstall everything, so does anyone know what my bootloader isn't seeing, but needs to see in order to push the update through?
Also, my phone isn't reading my brand new 64gb SanDisk evo suddenly. Was reading it fine last week... And ideas?
I'm on stock rooted ZV8 with sprint naval kernel.

partitions may be zv4/zv6 on your phone? that may be why you cant do the OTA. what about dirty flashing stock rooted ZVA(not recommended, but works great for me)? there is a navel kernel for it also. Make a backup and if you dont like it, flash back? what connectivity fix does the ZVA update claim? I thought the only (LISTED) update was they added factory reset protection?
He can't take the OTA cause he has TWRP installed. OTA will only install with stock recovery. Probably will need to use the flashtool to go to complete stock if you want to receive the OTA.

He said he put stock recovery back on, but yes he would probably need to flash completely stock to do the ota

Guess I should have read that better, sorry. As stated, try the rooted ZVA. OTA can be stopped due to edited build prop, debloating, etc. So complete stock through flashtool or flashing a rooted ZVA would be the only way to get to the new version.
