now go to Settings > Applications > Development > and check USB Debugging.

3 ) INSTALL USB DRIVERS

Install the Samsung USB drivers from my pack.

Connect phone to PC and wait phone drivers installation.

Desactivate your antivirus (Bitdefender and Windows defender blocked SuperOneClick from running on my PC).

Run SuperOneClick.exe from my pack.

(Make sure phone is connected and USB debugging is written in Android menu. If not, see above for USB debugging)

Click on Root and wait during operations.

When prompted, install Busybox.

When success message appears, you can close SuperOneClick.

### If root fails, your Antivirus deleted files. Redownload SuperOneClick and root again.

Now on phone: Open the new superuser app.

Tap on bottom left menu of phone to reveal app menu > Preferences > Automatic response > tap on Allow.

superuser will accept all operations (and prevent fail on next step).

5 ) UNLOCK/DEBRAND/DESIMLOCK PHONE

Connect phone to PC again.

Connect the phone as Mass USB storage.

Copy the 2 APK from my pack on main folder of phone's storage (phone appears as a USB key in Windows explorer).

Tap on it and select Package installer, confirm install.

Restart phone.

### It can crash multiple times, try again until it doesn't.

Tap on Install button at the bottom of screen and wait during Busybox install.

Now open My Files app again.

Tap on Galaxy S Unlock apk file.

Tap on it and select Package installer, confirm install and Open app.

Once in Galaxy S Unlock app.

Sceen may become black, app is laggy. Just be patient.

Go to Unlock tab.

Tap on Step 1 Backup files and wait during backup of phone's IMEI.

Tap on yes to backup actual efs partition (phone's IMEI)

Continue with Step 2 > yes
