This page has the download link and a step-by-step guide to flash the stock firmware on the Samsung SM-G930U, the US unlocked Galaxy S7, using Samsung’s Odin flash tool.
Flashing the stock ROM is how you put the phone back on official firmware. It is the usual fix for a lot of software trouble: a soft brick or boot loop, broken Wi-Fi or Bluetooth, or general lag and stutter after a bad update. It also returns the phone to a clean, unrooted state.
Samsung Galaxy S7 SM-G930U (US Unlocked) firmware flash file
This is the last official firmware for the G930U, which is Android 8.0 Oreo. The S7 never received an official update past Oreo, so this is as current as the stock ROM gets.

Build Number: G930UUESBCTA3
Model: SM-G930U

This is a four-file firmware, so after you extract the zip you should have separate BL, AP, CP, and CSC files.
Steps to flash firmware on the Galaxy S7 SM-G930U
Before the steps, run through the requirements below.
Pre-requirements
- This guide is for the Samsung Galaxy S7 SM-G930U (US Unlocked) only.

- Charge the phone to at least 50%.
- Download and install the latest Samsung USB drivers on your PC.

Installation guide
- Download the SM-G930U firmware and extract the zip. You should end up with BL, AP, CP, and CSC files.
- Open Odin on your PC.
- Load each file into its matching slot: BL, AP, CP, and the CSC file in the CSC slot. Using the regular CSC file does a clean flash and wipes the phone. If you want to keep your data, load the HOME_CSC file instead where one is included.
- Boot the phone into Download Mode, then connect it to the PC.
- Odin should light up the COM port once the phone is detected.
- Click Start to flash the firmware.
- When it finishes, Odin shows a PASS message and the phone reboots. The first boot can take several minutes.

Frequently Asked Questions
What Android version is this firmware?
Android 8.0 Oreo. That is the final official software for the US unlocked Galaxy S7, so there is no newer stock build to flash. If you want a newer Android version, you would need a custom ROM like the ones in the Also Read links above.
Will flashing erase my data?
It depends on the CSC file. The standard CSC file wipes the phone during the flash. If the firmware includes a HOME_CSC file and you use that instead, it can keep your data. Back up either way before you start.
Does flashing stock firmware trip KNOX?
No. This is official, Samsung-signed firmware, so flashing it with Odin does not trip the KNOX counter the way unlocking the bootloader or flashing a custom ROM does.
Can I downgrade to an older version with this?
Not always. Samsung uses anti-rollback protection on the bootloader, so you cannot drop below the bootloader version your phone is already on. Flashing a build with an older bootloader than your current one can fail or brick the device, so match or stay above your current bootloader version.
Does this work on other Galaxy S7 models?
No. This firmware is only for the SM-G930U. Other variants such as the G930F, G930V, G930T, G930P, and G930A use their own firmware, and flashing the wrong one can brick the phone.
Conclusion
Flashing the stock G930U firmware with Odin is the reliable way to get a US unlocked Galaxy S7 back to a clean, working state after software problems. Match the firmware to your exact model, back up first, and let the flash finish on its own. If you run into trouble, drop a comment below and tell us what Odin reports.
