My lock code my phone k800 is lock

You may try by following instructions....
Warning: Do not enter any wrong unlock unlock codes on your Sony Ericsson K800 mobile phones. If you enter over a certain amount of wrong unlock codes on your mobile phone, your phone may get hard locked and sometimes become unusable.

1 - Switch ON your Sony Ericsson K800 mobile phone without any SIM Card,
2 - Press the left arrow key/button once,
3 - Press the button * twice,
4 - Press the left arrow key/button once,
5 - The message "Personalize with MNC2" will appear,
(or you will have displayed an unlock menu, select the lock you want to unlock)
6 - Enter the Unlock Code.

If your Sony Ericsson K800 mobile phone does not have a left arrow button/key(e.g. Sony Ericsson W950i) and on a few phones(not all) that have a "JOGDIAL" you must press the "down arrow" key/button instead of the "left arrow" key/button for step 2 & 4. We mean by "Down Arrow" to direct the Jogdial down! In the Sony Ericsson W950i and some other models, the down arrow button/key would be located on the side of the phone.

I upgraded the software for sony ercsson K800. The keys got messed up. the green one connects internet which operated the phone calls before.

You have to contact Sony Ericsson and have them re-flash the firmware on your phone. They are the one who knows the firmware version that would work best for your phone.

Have a great day!
