Link: CWM Recovery for all SGS3 LTE variants
Instructions for CWM recovery to enable rooting and customization of all SGS3 LTE variants. This is confirmed to work great on Sprint, AT&T, T-Mobile and Rogers variants.

EDIT: Please note if you just received a new Sprint S3 and after following this procedure you cannot access internal or external storage from CWM please see THIS THREAD
  • Updated: 6/30/2012
  • version 4: Excludes /data/media from backups.

Link: Root from Recovery
Simply flash this.zip in CWM and your phone is rooted! This is the easiest method to root the stock Samsung ROM.
  • Updated: 7/3/2012
  • version 5: Now automatically cleans out old root files to prevent conflicts. This should fix failure to root.
  • version 4: Removes /system/etc/install-recovery.sh and /system/recovery-from-boot.p left by OTA updates in order to preserve stock recovery. Read the CWM instructions carefully!

Link: Unroot .zip and Stock Restore
Follow these insructions to unroot and restore the modification status to "Normal".

News: Important News for Sprint's LF9 OTA Update

6/30/2012:
  • Sprint SGS3 received the LF9 OTA update from Sprint today. If you used our previous root method, applying this OTA update works. After applying the update, you need to flash the latest version of our Root .zip in order to retain custom recovery and root status. You may also want to upgrade to CWM for SGS3 LTE variants version 4 as it contains an important fix for backups.
  • Reportedly LF9 fixes the Google Wallet not Certified issue.

Do I have to re root (flash the root from recovery.zip) after updating from the oldest CWM to the newest?

No, although you need Root .zip v4 after you upgrade to yesterday's OTA.

ODIN'd back to stock, found my security update inside the internal cache (stock recovery) and was able to run it from there just fine....yup, had unrooted and run the update; it downloaded but failed to activate.

ODIN'd cwm/rooted then opened wallet, activation went fine........after, ran the Store update: now I get the Unsupported Device message (4 rooted devices)............go figure!

** still, wallet works just fine! Rooted users, just ignore the message........all wallet users should be aware: your working wallet needs to be reset direct from the open app (not cache/not data) PRIOR to flash or device hard reset. Otherwise you may end up borking your wallet and bricking the secure element. So, prior to flash: open wallet then navigate Menu/Settings/Reset google wallet.........now you're free to flash.

Question is there an app for protecting root while keeping up with latest OTA
since voodoo root keeper does not work with the galaxy S3, If someone can recommend a procedure/process to follow to maintain root and keep up with sprints updates please?

I'm just trying to figure out what the best & least time consuming way to maintain root and keep up with sprints updates please?

hopefully my questions made sense to you all...thank you all (in advance) for helping/answering my questions...

-peace
