The Galaxy S3 is one of the best smartphones on the planet. If you have the international version of the device, it’s very easy to root and install a custom recovery on it. But the scene changes when it comes to rooting a Galaxy S3 from Verizon, the largest network provider in the US. Most devices from the carrier come with locked bootloader and therefore the procedure becomes a little complicated.
While the other variants of the Galaxy S3 received the Android 4.1.2 Jelly Bean update months ago, the Verizon Galaxy S3 SCH-I535 lagged far behind and finally received the 4.1.2 OTA update in early March. Usually, the user is not able to receive the official updates on a rooted device and installing official firmware manually takes away the root. Thus, root and update are contradictory things.
But Android is a wonderful world of possibilities! You can install a pre-rooted stock firmware without an increment in the flash counter of your device, or install the OTA update even if your phone is rooted. And what is the better part- it’ll also preserve the root, custom recovery and unlocked bootloader! Now this is really great because it saves a lot of time, effort and risk.
If you have a rooted Verizon Galaxy S3 SCH-I535 with CWM or TWRP Recovery installed on it, you can download the appropriate OTA update package from below and install it using custom recovery. These OTA update packages are modified versions of the official releases.
These updates are for Verizon Galaxy S3s that have been rooted, with custom recovery, unlocked bootloader, and have Google Wallet and the associated NFC libraries installed. If you did all those things to your S3 and want to apply the stock OTA updates, this is for you.

Please note that these OTA update packages are only meant for Verizon SCH-I535 with rooted stock TouchWiz firmware. Installing them on any other base might prove fatal to your phone.
If you have ever used ClockworkMod or TWRP recovery, installing the OTA packages should be an easy job for you. In case you are new to such things, follow the quick steps given below:
When the phone boots up, it should have the newly updated firmware installed on it. Enjoy!
