How to Boot GSI ROMs Temporarily with DSU Sideloader – No Flashing Needed (SAFE)
Make sure your device has an unlocked bootloader. Root access is optional but recommended.
Download DSU Sideloader and the desired GSI ROM.
If you're using Magisk or KernelSU, grant root access to DSU Sideloader when prompted..
Inside DSU Sideloader:
- Open the app and go to Settings.
- Enable "Unmount SD" and "Built-in Installer" options.”
- Set the Userdata size based on your storage needs.
This will be used to store your apps and data while running the GSI.
- Select your ROM ZIP file, then tap Install.
Booting into the GSI ROM:
- Once the installation is complete, tap "Reboot to DSU".
- Go to Play Protect.
- Your phone will reboot and load the selected GSI ROM.
Switching Between ROMs
- To return to your main (stock) system, simply reboot your phone.
- To boot back into the DSU ROM later, open DSU Sideloader again and select "Reboot to DSU".
- Your data will not be lost, as the Userdata partition is already set up.
This app is safe to use and virus-free. Android shows a warning simply because the app is not from the Play Store, not because it's harmful.
