How to reprogram my sony ericsson k800i


Instructions

Obtain the unlock code for your K800i if the phone is locked. You can get the code from an unlocking service, or from the carrier that originally sold the phone.

Turn off the K800i and turn the phone over.

Remove the battery cover by sliding it toward the bottom of the phone. Lift the battery from the bottom and set the battery cover and battery aside.

Remove the old SIM card by sliding it out from under the metal clip. If you have an unlocked K800i, all you need to do is insert the SIM card from your new carrier. Otherwise, leave the SIM out and reinstall the battery and battery cover.

Turn the phone on and wait for it to boot up.

Press left on the navigation pad and press "*" twice, then press the left arrow again. The phone will display "Personalize with MNC2."

Type the unlock code and wait for the phone to reboot.

Turn the phone off and insert the new SIM card.

Sony ericsson k800i blank screen need to transfer numbers from phone memory to sim card


Thats a cool phone, pity its screen is broken.... Here is my suggestion
  • If you got keypad lock then unlock the phone
  • Go to menu usually by pressing the top right key...
  • Press 8, which should take you to contacts
  • Press the top right key which would take you to More
  • Press up using the joystick, this should highlight Options
  • Then press the middle of joystick, which would take you into options
  • Press up using the joystick again, this should highlight Advanced
  • Press 5 to backup the contacts to memory card or press 8 to back up your contacts to SIM
Check the memory card or Sim on another phone...

Problem with Swtching on the Sony Ericsson K800i mobile


You have to Upgrade the EROM and the SW. It's done by service software only, something like setool and cruiser tools.Search on google for setool and cruiser.

I think there is a setool lite version who can help you solve the problem for free just by reflashing the SW of the device.

Unlock code


  1. If you have changed your phone password, change your password back to the default 8 zeros (00000000).
    NOTE (Modification here by my experience): Go to SETTINGS, SECURITY, then SIM LOCK and disable this before proceeding.

  2. Put a SIM card that is from a network other than the one your phone is locked to.

  3. When Incorrect SIM error comes up, input *#9998*3323#.

  4. White screen will appear with an exit option. Press the right softkey.

  5. From the menu that appears, select the Malloc Fail option. This will reboot the phone and the normal service screens will appear.

  6. Type *0141# and then press the green call key. "Personalization" or "Personalized" will appear.

  7. Turn off your phone and put the original SIM back in.

  8. Turn on your phone. You will receive a prompt to enter a password.

  9. Type 8 zeros (00000000) (This is because the SIM LOCK Mentioned earlier gets switched back on)

  10. Completed. You have now unlocked your phone.

    You now have an UNLOCKED Samsung D807

  11. With the studio software from samsung you are able to edit and move contacts from your phone to the sim and back. Or copy from the phone and put them on the sim card.
