Vick: I understand that you are unable to connect to Kies mini, am I correct?

Vick: Thank you for confirming.
Visitor: another question?
Visitor: are you a real person or am i talking to an automated?
Vick: I sincerely apologize for the inconvenience.
Vick: Please go ahead.
Visitor: are you a real person?
Visitor: or automated?
Vick: I'm sorry. I'm a real person.
Visitor: ok making sure :smileyvery-happy:
Visitor: so are you going to help me or????
Vick: Yes. Absolutely.
Vick: Just to confirm, may I know the exact error message while you connect the phone?
Visitor: unregistered device
Visitor: on kies mini
Visitor: on the other kies
Visitor: it says
Visitor: this phone is not supported by kies
Vick: Just to confirm, did you register the phone with Samsung?
Visitor: yes
Vick: Just to confirm, did you receive the notification on the phone regarding the update?
Visitor: no?
Visitor: what update?
Vick: I see that you may get connected to Kies mini only if you may receive the notification. However, Android 2.2 is released for your phone and you may receive the notification in couple of hours, then you may get connected to Kies to update the firmware.
Visitor: so why is it saying unregistered device?
Vick: I'm sorry. I recommend you to perform the soft reset to troubleshoot the issue that you are facing with the device. This might fix the issue.
Vick: 1. Turn off the handset.
Vick: 2. Remove the battery and wait for 30 seconds.
Vick: 3. Reinsert the battery and turn ON the device.
Vick: Please perform the above the procedure and let me know the status.
Visitor: doing that now
Vick: Sure. I will be waiting for your response.
Visitor: ive been reading forums and alot of people have been able to get this update
Visitor: while alot of people are still having the same problem that i am having
Vick: I'm sorry. The update is released in Phases. You will also receive the notification in couple of hours that you may update the firmware.
Visitor: ok but once i recive this notification
Visitor: does that mean ill be able to use kies without having problems?
Visitor: it says
Vick: Yes. Exactly.
Visitor: Model Name : SGH-T959 (myphone#)
Visitor: Firmware Version : Unregistered device
Visitor: Firmware upgrade :
Visitor: its not letting me connect at all
Vick: I'm sorry. I see that you might be able to get connected once you receive the notification.
