Don’t update to latest Verizon or AT&T Galaxy S4 updates if you want root & unlocked bootloader
The latest Samsung Galaxy S4 update for Verizon and AT&T are a tad bitter-sweet. On one hand, it brings a much-needed feature in Apps2SD, improved performance and the base for Samsung KNOX security features. On the other hand, it will break root and the exploits which allowed users to unlock their bootloaders. That said, it’s best to steer well clear of this update if you value root and a phone freed from chains more than Apps2SD.
For Verizon, you’ll be looking to avoid firmware VRUAME7. For AT&T, it’s I337UCUAMF3. That said, the updates are perfectly fine if you’re not one to root your phones and flash custom ROMs. If you want to proceed, you can check the software update menu on your AT&T Galaxy S4 to grab it over-the-air (might want to be on WiFi as it’s a hefty 360MB), and Verizon users can follow the instructions here to apply the update over Kies. Let’s hope the community can find new exploits before too long.
