One UI 4.1 and One UI 2.5 Ported ROM for Samsung Galaxy S7/S7 Edge

The Samsung Galaxy S7 and S7 Edge shipped with Android 6.0 Marshmallow and only made it to Android 8.0 Oreo officially. The custom ROM scene took them much further, and you can now run Samsung’s own One UI on them through ports built from newer Galaxy phones.

This guide covers two options. The newer one is One UI 4.1 (Android 12 based) through the Eylem ROM, ported from the Galaxy S10 5G. The older, lighter one is One UI 2.5 (Android 10 based) through FloydQ V5.0. Both are below, so pick the one that suits your phone.

One UI 4.1 ported ROM (Eylem ROM, Android 12)

Eylem ROM is a One UI 4.1 port based on Android 12, built from the Galaxy S10 5G software. It brings a much newer One UI interface than the One UI 2.5 port further down this page, so it is the one to go for if you want the closest thing to a modern Samsung experience on this hardware.

The build covered here is Eylem ROM v8.0, and it supports the Galaxy S7 (herolte), S7 Edge (hero2lte), Note 7 (grandpplte), and Note FE. Because it is a port from another device, some features may be incomplete, so check the XDA thread for the current list of what works and what does not before you flash.

The XDA thread has the download, the firmware or bootloader it needs, and the exact flashing notes for this port, so follow those alongside the general steps near the end of this guide.

One UI 2.5 ported ROM (FloydQ V5.0, Android 10)

If you would rather run something lighter, the older One UI 2.5 port is still a good option, especially on a phone that struggles with a heavier Android 12 build.

FloydQ V5.0 is the work of XDA Recognized Developer ananjaser1211. It is a feature-rich but stable One UI 2.5 port for the S7/S7 Edge.

Download One UI 2.5 (FloydQ V5.0)

• ROM OS version: Android 10
• Based on: One UI 2.5
• ROM kernel: Linux 3.x
• Firmware required: latest bootloader/modem and TWRP 3.3+
• Download ROM: FloydQ_V5.0_Exynos8890.zip

Requirements

These apply to either ROM. Go through them before you flash.

• Create a complete device backup, since the install wipes the phone.
• Enable USB debugging and OEM unlocking: Settings > About phone > tap Build number seven times, then Settings > System > Advanced > Developer options > turn on USB debugging and OEM unlocking.
  
• Install the Android SDK Platform Tools on your PC.
• Unlock the bootloader. If you have not done this, follow our guide for the Galaxy S7 or S7 Edge.
• Install TWRP recovery. That guide also covers rooting, which is optional. Use a recent TWRP build for the One UI 4.1 port.
• Make sure you are on a recent bootloader and modem, and meet any firmware requirement the ROM’s thread lists.

How to install the ported ROM on the Galaxy S7 / S7 Edge

These steps work for either ROM. Flash the ZIP you downloaded, and follow any extra steps the ROM’s own thread gives.

1. Copy the ROM ZIP to the phone’s internal storage.
2. Connect the phone to the PC with a USB cable, with USB debugging enabled.
3. Open the platform-tools folder, type CMD in the address bar, and press Enter to open a Command Prompt.
   
4. Boot the phone into TWRP:

   adb reboot recovery

5. In TWRP, go to Wipe > Advanced Wipe.
   
6. Select the System, Data, Cache, and Dalvik partitions and swipe right to wipe them. If you are switching between ROMs or the phone is encrypted, use Format Data (type yes) so the new ROM will boot.
7. Go to Install, select the ROM ZIP, and swipe right to flash it. Flash any add-ons the thread specifies, in the order it lists.
8. When flashing finishes, go to Reboot and select System.
   

The first boot can take several minutes, and you will set the phone up from scratch afterward.

Frequently Asked Questions

What is the difference between the two ROMs?

Eylem ROM is a newer One UI 4.1 port based on Android 12, so it looks and feels closer to a modern Samsung phone. FloydQ V5.0 is an older One UI 2.5 port based on Android 10 that is lighter and can run better on this aging hardware.

Which devices does the One UI 4.1 port support?

The Galaxy S7 (herolte), S7 Edge (hero2lte), Note 7 (grandpplte), and Note FE. The One UI 2.5 FloydQ port targets the S7 and S7 Edge.

Will installing a ROM erase my data?

Yes. Unlocking the bootloader and wiping/formatting data both erase the phone, so back up first.

Does flashing trip KNOX?

Yes, and it is permanent. Unlocking the bootloader and flashing a custom ROM trip the KNOX counter, which voids the warranty and disables KNOX features like Samsung Pay and Secure Folder.

Is the One UI 4.1 port stable enough for daily use?

It is a port from another device, so some things may not be perfect. Check the current working and bug list on its XDA thread before relying on it. If you want something lighter and settled, the One UI 2.5 port is the safer pick.

Conclusion

Between these two ports, the Galaxy S7 and S7 Edge can run either a modern One UI 4.1 (Android 12) or a lighter One UI 2.5 (Android 10), well past where Samsung left them. Back up first, match the ROM to your exact model, and follow the ROM’s own thread for anything device-specific. Tell us in the comments which one you went with and how it runs.
