How To Unlock Samsung L770

To start unlocking Samsung L770, please read every step carefully and your Samsung device will be unlocked in minutes.

These are instructions with fewer details. If you prefer instructions with pictures, please skip this guide and download the PDF version here:

  1. Shut down your PC’s firewall and antivirus. Connect to the Internet with a standard high speed connection and not a wireless modem, a VPN, or a Proxy. Unlock at home and not at a company.

  2. Download the unlock software and install all items.

  3. If you have the software Samsung Kies or PC Studio installed, uninstall it from your PC. Reboot computer.

  4. Insert original SIM and turn phone on. If you don’t have one, don’t insert any. In case you see the “Phone Freeze” error, don’t use any SIM either.

  5. On your phone, make sure Bluetooth is turned off. Increase screen time out to the maximum if available.

  6. Connect phone to PC. Select Kies Mode in case the phone gives you the option to do that.

  7. Launch GalaxyUnlocker software on your PC. Enter your username and password and connect (if you don’t have one, buy it here).

  8. Press the Rescan button. If the software gives you the error that ports have not been set correctly, download the PDF file above and see step 9 at the end of the document for instructions on setting ports correctly.

  9. Click Direct Unlock. GalaxyUnlocker will now unlock the phone automatically. Beware: this process can take 4 hours!

  10. Your Samsung L770 is now unlocked.
