Hello

*#7370# .......... Format phone...[Hard-Reset]
*#7780# .......... Factory Reset

if that doesnt work in case you lost your lock code, try:

Turn phone off, press and hold the green (talk) key on the left + number 3 on the keypad + the * key + the on button.

good luck

Read through this until you find how to reset the brw unit thyen follow the directions.
Remove the dredge drawer. Open the door. On the left side of the brewing unit, and towards the back of the brew group, there is a single screw. Remove the screw. Grab the handle and pull carefully, but firmly with a quick ****. The brew group should come out. There is a piece that remains in the machine. Slide that piece down and to the right and it will come off. Insert the piece into the hole on the backside of the brew group with the clip up. Tighten the screw and move brew group back into position.
To return the brew group to the centered position, you first need to drop the funnel. To do this, look on the opposite side of the brew group from the handle. At the top you will see an object that looks like a sharks fin. If you follow this piece down you will see 2 horizontal bars on the brew group body. Push your finger between these 2 bars and the funnel will drop. Now you can push the puck slide on the left side down and to the center. (You can insert your key into the hole in the front and twist the key to return the brew unit to the center. Line up the 2 diamonds and it centered) If you look down through the funnel you should see a piston. This should be centered in the funnel. If not, locate the slide on the left side of the brew unit,(it should be hanging down, a flat rectangular piece attached to the cylinder) and push the slide to the right until it does. Push the press button and you are now ready to reinsert the brew group in to the machine. First you must close the door and turn on the machine without having the brew group in, but you must have your drip tray and dredge drawer in. Turn the machine on. You will hear the motor turn on and when it stops completely, open the door and remove the tray, now insert the brew group and replace the tray.

Hi
Leave the brew unit out but put everything else back in and then turn the machine on. the brew drive should reset to where it should be so you can put the brew unit back in, but make sure that the brew unit is ready to install.
You must make sure that the brew unit is ready to reinsert into the machine. To return the brew group to the centered position, you first need to drop the funnel. To do this, look on the opposite side of the brew group from the handle. At the top you will see an object that looks like a sharks fin. If you follow this piece down you will see 2 horizontal bars on the brew group body. Push your finger between these 2 bars and the funnel will drop. If you have you key you can insert it in the front of the brew unit. There is a round hold in the center below the "Push", and twist it clockwise until it stops and the 2 marks are lined up. If you don't have your key you can do this. Push the puck slide on the left side down and to the center. If you look down through the funnel you should see a piston. This should be centered in the funnel. If not, locate the slide on the left side of the brew unit, (it should be hanging down, a flat rectangular piece attached to the cylinder) and push the slide to the right until it does. Press the "Push" lever until you hear a click and you are now ready to reinsert the brew group in to the machine.

check the side button PTT

and make full reset

Try *#7370# .......... Format phone...[Hard-Reset]

That formats everything.
But in case you forgot your lockcode.

Switch it off, press and hold the green (talk) key on the left + number 3 on the keypad + the * key + the on button.

go to settings and press factorysettings

no make or model listed
on many phones there is an ability that when the phone is picked up it is automatically connected to the caller and pressing the answer button is the same as hanging up
as for you second point , if a caller rings but hangs up before the message beep or after the beep but hangs up , there will be no message recorded
