Flash the stock firmware via Odin. You can find it in a thread in the general section.

If you don't care about custom recovery you could always go back to stock with kies.

do I need root to slash stock rom?

Do I need to root my phone to flash Stock roms via Odin? I want to flash the Stock rom and I wonder if it gonna lose the IMEI? thanks guys
Nope. But you do need root to install a custom recovery like TWRP or CWM. There may be another method but im not familiar with it at the moment.
Anyway you can easily dl one of the stock firmwares from samfirmware.com and install using odin. Provided you just want pure stock.
And you shouldn't have to worry about losing your imei flashing stock with odin. I dont recall that ever hapoening. Besides, imei issues have been solved. Just check the dev section for info.

thanks for your reply
btw, I'm on stock with latest Tmo update now. Let say I want to flash stock without that update (stock before the update). how does it change my stock recovery? is the recovery still the stock with latest Tmo update?
I dont really understand how the stock recovery works. after I apply the update, is the update applied to the stock recovery too?
As far as I am aware it will rewrite your stock recovery back to whatever version you are installing as well. So long as you use odin and a full firmware file from Samsung.

[Q] SGH T999V Back to Stock so i can get OTA from Samsung

So I'm Custom Firmware FrostyJB and want to go back to stock as this has a few bugs. and i want to recieve OTA from Samsung.
I made a nandroid but my phone does not seem to register it.
any idea what i should do?
You have to restore a nandroid backup with the same recovery you made it with.
Otherwise download the stock fw and flash with odin. Flash the VLALH2 and youll have the up to date fw already. No need to wait for ota to dl and install.

Why not flash an ics Rom instead of jb leaks if they're not working for you

Updating rooted with custom rom

If I wanna upgrade to the official JB and my S3 is rooted with custom rom, is it safe to upgrade to official jb via Kies? Or should I go back to stock ics before upgrading?

If you want to go from a custom ROM to stock JB, Kies won't do it. You will need to flash via Odin. You will loose root and your custom recovery.

Link please ? Do that Odin program and how to flash JB on it
If you're going to have to use odin anyway, you should consider installing mrRobinson's root-injected stock jellybean rom. Then you won't have to worry about rooting it. Worked awesome on my stock rooted ICS with stock recovery. Also worked awesome on my son's stock rooted ICS with CWM. Here's the link. Everything you need to know is in the first post.

Do I need to get rid of my custom rom if I wanna upgrade? If I don't, will it brick it?

Get latest firmware for your note 2 model and region
download it from here
http://samsung-updates.com/
get in downlaod mode and then flash it via odin
its all in one package so you will have to click on PDA tab and select the stock ROM you downloaded ..nothing else needed
If you want to backup your alliance ROM you can do it in recovery incase you would like to come back if anything goes wrong then you would have option to switch back to alliance ROM

How to go back to 4.3 from 4.4.2

How do you go back to 4.3 after taking the OTA and then rooting it? I dont want to brick my phone. I have the 4.3 stock rom from sammobile that i could flash using Odin but not sure if that will work?

Best practice is to flash custom recovery then a custom rom. If you try using odin or other methods then an issue may/can arise. If you only flash custom roms you will have no issues with bricking hard or soft.

I used Odin to do a complete restore back to 4.3. I like a fresh start, seems I have less issues that way. Worked great then I rooted with cf auto root, then back to smoothest rom 2/3 imo.
