Verizon has finally released a new firmware update for the Samsung Galaxy S4 (SCH-I545) with Build number VRUDMI1 in mid October, not as we expected earlier that this update brings only minor changes and may contain security fixes with the same Android version 4.2.2. As in general, a software upgrade will remove root on this device, so our device will lose root access after applying the update. And the previous root method can’t deal with the new software, so we have to use another method to root the Verizon Galaxy S4 running VRUDMI1 firmware.
Thanks to superb developers on xda-developers who managed to deliver us a new method to regain root on VZW Galaxy S4 on latest I545VRUDMI1 firmware, they called it the “Root De La Vega”, which previously built for the Samsung Galaxy Note 3, and @beanstown106 from xda ported it to our VZW GS4.
Here is a step by step on how to make our Verizon Galaxy S4 with VRUDMI1 rooted, the method requires us to flash modified kernel via ODIN before applying the Root De La Vega exploit. Be sure to backup all your important data before making any mods to your phone.
- Pull off the external SD card if you have one installed.
- Set up VZW Galaxy S4 device drivers if you haven’t set it up before.
- Download the root package (rootdelavegajfltevzw.7z) from the dev’s thread.
- Grab Odin flash tool, the dev encouraged us to use the 3.07 version.
Flash MD5 File via Odin
- Extract the root package then find a flashable file (VRUDMI1_Root_de_la_vega_jfltevzw.tar.md5).
- Put the VZW Galaxy S4 into download mode (push and hold Volume down + Home + Power button at the same time) then connect it to a desktop PC.
- Run the Odin3 v3.07.exe, click the PDA button then locate the flashable file above.
- When the device has been recognized by Odin, now it’s time to flash by hit the Start button.
- Once done let the VZW Galaxy S4 restart.
Verizon Galaxy S4 VRUDMI1 root using “Root De La Vega” script
- Find the Rootfiles.zip from the root package, extract it again until you see the script (root_de_la_vega.sh) and a folder (root_files).
- Copy it directly into the internal SD card , once done now reboot the phone. The script will now attempt to gain root, automatically.
- After fully boot up, now remove the script, then restart the phone again to make sure all the root exploit has been installed correctly.
Our Verizon Galaxy S4 with I545VRUDMI1 firmware should rooted now, go to Play Store to and get some root apps to verify it. Consider to block future OTA to prevent accidental update.
