Method 1: Force restart the Galaxy S26

A forced reboot can break a temporary restart loop caused by a failed first boot.

1. Press and hold the Volume Down and Power buttons together for about 15 seconds.
2. Wait for the Samsung logo to appear.
3. Let the phone try booting normally again.

Method 2: Remove accessories and let the phone cool down

Overheating or a faulty USB accessory can keep the startup process unstable.

1. Disconnect chargers, cases with battery packs, and USB accessories.
2. Let the phone cool for several minutes.
3. Try powering it on again.

Method 3: Boot into Safe Mode

If the Galaxy S26 reaches the lock screen, Safe Mode can confirm whether a third-party app is causing the loop.

1. Turn the phone on and hold Volume Down when the Samsung logo appears.
2. Keep holding until Safe Mode shows on the screen.
3. Remove recently installed apps if the phone stays stable there.

Method 4: Wipe the cache partition from Recovery

Update-related boot loops are often fixed by clearing the old system cache.

1. Boot into Recovery Mode.
2. Choose Wipe cache partition.
3. Reboot the phone and test it again.

Method 5: Charge the phone fully before another boot attempt

Low battery during the first post-update boot can leave the device stuck.

1. Charge the Galaxy S26 to at least 50 percent.
2. Use the original charger if possible.
3. Try another normal restart after charging.

Method 6: Check for Recovery Mode options to repair apps or reset

If the boot loop continues, deeper repair steps may be necessary.

1. Return to Recovery Mode.
2. Use available repair options first if the current build provides them.
3. If nothing works, back up what you can and prepare for a factory reset.

Method 7: Factory reset or seek Samsung service

A full reset is often the last software fix when the update installation is badly broken.

1. Choose Factory data reset from Recovery only after other methods fail.
2. Set the phone up again and install apps gradually.
3. If the loop returns immediately, book Samsung hardware diagnostics.
