Try to master reset the phone and (back up everything before) if that doesn't help, flash the phone with SEUS (Sony Ericsson Update Service).

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.

When i open the gallery, phone shuts down

what has happend is that the phone has detected a virus, like if you have ever used the wire that came in the box to connect to your computer to charge or to create mass storage and the computer has an undetected virus that can get into the phone via the wire, so what i recomend you do is that you scan your computer for undetected viruses, and also restore factory settings on your phone turn it of for 30 seconds turn it on and try again, if this does not work contact your service provider or LG themselves and treat the situation from there.

Sony K800i always "hang"

It hangs because ur phone is having a hard time managing and organizing ur files.
For me it could be better if you upgrade to 1gig and ur phone will perform better.
For the reason that the files in your phone is organized well,therefore, faster performance.
