However, most rooted users take a step back on updates because the root will be lost once the firmware is flashed. But muniz_ri of XDA has shared a simple procedure to flash the latest firmware on your Verizon Galaxy S4 without losing the root. You can update to the OF1 firmware on your Verizon S4 using a tool called Flashfire developed by Chainfire, the wonder developer of SuperSu. The Fireflash app is a new mobile flash tool which has the capability to flash a stock firmware OTA directly from your device.
So, without any further ado, let’s see how to update Verizon Galaxy S4 to OF1 firmware without losing root.


This tutorial is only meant for Verizon Galaxy S4 with the model number SCH-I545, don’t try this on any other variant of Galaxy S4. Flashing firmware is considered risky and might brick your device in extreme cases, so follow the procedure carefully to avoid any hassles. We are not responsible for any damages to your device during the process, so proceed at your own risk.


  • Make sure your device is charged above 60% to avoid unexpected shutdowns during the rooting process.
  • As you want to retain root, we assume that you have already rooted your device. If not, follow this link.
  • Make a nandroid backup of your device so that you can restore the backup if needed.


Installation Instructions

  1. Download and install the latest version of Flashfire app from the above link.
  2. Download the OF1 stock ROM of your choice (Odexed or Deodexed) and transfer it to your device’s storage.
  3. Now open the Flashfire app and grant SuperSU permissions if prompted.
  4. In the app, tap on the Plus (+) button and choose the “Flash ZIP or OTA” option. Leave the Auto-mount option unchecked and press the Checkmark symbol to continue.

  6. Finally, hit the lightening bolt icon to start flashing the firmware.
