4.4 and 4.3 Sticky Roll-Up Thead
Do not use EZ-Unlock! You will instantly hard brick your phone and you will have to go through a painstaking hardbrick repair or get a JTAG repair.
Thread Purpose
The official 4.3 touchwiz update brought significant changes to the Verizon Galaxy S3. Once you took the update, the phone is completely stuck on the 4.3 or 4.4 base and any attempt to change the rom (unless using safestrap) will brick the device. Previous rooting and unlocking methods will no longer work on the update and will cause bricks if used. However, there are great threads going around regarding the update but are fragmented all over the device sections. We need a place to have all the information available on the new update. The old sticky roll-up thread should be used for anyone who still has an unlocked bootloader, meaning you did not take the 4.3 or 4.4 OTA update or your phone did not come with it pre-installed.
If you have 4.4 NE1 baseband you are unable to go back to any version of the 4.3 updates. Running any kind of 4.3 rom in safestrap will not work, and installing a stock 4.3 rom will brick your phone. You are limited to using a modified safestrap located in this thread, with no current modified custom roms.
This thread should strictly be for reference only, meaning posts should only be made if you believe a specific thread should be linked in the OP. If you want to discuss any aspects of this update that you're confused about, please use the 4.3 discussion thread (first linked sticky) or post your question in the Q&A forum. Keeping post counts low will make it easier for new members to access the information they need, so please post appropriately.
How can I tell if I have the official 4.3 or 4.4 update if I bricked my device?
It's important to know what base you're on so you can fix a brick. In any circumstance except a hard brick, once you boot into download mode you will see one of three possibilities:
If you're on a 4.3 or 4.4, you're in the right place:
4.3
Product Name: SCH-I535

Warranty Bit:0
Bootloader RP Swrev: 0
4.4

Use this if you bricked your device, and you're still able to access download mode. You can also use this guide to return completely to stock if you need to.
For NE1 you need to use an appropriate NE1 stock rom, not the 4.3 rom listed.
[GUIDE] Debrick your bricked SCH-I535! [BOOTLOADER/HARDBRICK]
Use this if you bricked your device and can't enter download mode. Computer will recognize device as QHSUSB-DLOAD, but other than that you have no other sign of life. You can also fix this problem with a JTAG repair if you can't get this method to work.
Useful Information
If you have 4.3 VRUCNC1 baseband, since wifi modules aren't available it is recommend to Odin flash the Stock 4.3 VRUCML1 rom then root and install safestrap. That way you will have working wifi after rom installations.
[FAQ] KNOX and you
Very useful information on KNOX that everyone should understand. However, we have a locked bootloader and the sprint device doesn't, so don't listen to what he's telling you about flashing AOSP roms. If you do it you'll brick the phone, just understand what he's saying about what knox is.
[FIRMWARE] (MODEM/RPM/TZ/SBL) Verizon SGS3 (SCH-I535)
Good information on the locked bootloader and why it can't be downgraded to a previous modem. Do not flash any files from this thread if you're on the 4.3 base.
I think that's all I can think of, hope this helps everyone who needs it!
