What are you trying to do ? I hope some of this helps.

12 menus appear that are unique to the Sony Ericcson k800i ...

K800i Secret Menu In this post I will write about a few hidden features of the K800i.
These codes should work on most Sony Ericsson models though, try for yourself.


Service Menu

The Service menu can be accessed by pressing the following sequence while in the standby screen:

right, *, left, left, *, left, *

The phone now shows a menu titled 'Service' with 5 menu items:

  • Service info : Here you can view information regarding your handset such as the model number, software versions (firmware as well as other versions, like camera driver version, etc.)
  • Service Settings : Here you can switch USB charging on or off
  • Service Tests : Allows you to test every component of your phone, such as the keypad, microphone, speaker, LED, Display, etc. Any fault can be found out easily with this method.
    In this section, You can also check the Total call time, the number of hours you have called.
  • Text Labels : Better leave this section alone.
  • Discharge Flash : To discharge the camera flash fully.

In addition to the Service Menu, SE's also offer a 'Personalize' menu.
It can be accessed by the sequence
left, *, *, left

But unlike the Service Menu, the Personalize menu is for trained experts only. So it's better not to tinker with these settings. Still, it's cool to know your phone's got all these things under the hood right?


Want to see something cool?

Access the ServiceMenu. Now Navigate to Service Info > Model Info.

While the Model is displayed, press the folowing key sequence :
2, 4, 6, 8

Stop thieves running up huge mobile bills by locking your Sony Ericsson K800i and protecting it with a PIN To protect your phone from unauthorised use you can set a phone lock to stop others using it.
The default phone lock code on the K800i is 0000, so it is best to change this number to one you can easily remember in case it is lost or stolen. To change your unlock code:
  • From the Menu screen, select Settings (Figure 1).
  • On the General tab, scroll down to Security (Figure 2).
  • Select Locks (Figure 3) and then Phone Protection (Figure 4).
  • Select Change Code (Figure 5).
  • Enter the default code then enter (And re-enter) your new one (Figure 6).
Once you have changed your phone lock, you can then set to either On, Off or Automatic (Figure 7). When it is turned On, you must enter your code when you turn the phone on, Off means you don't need to enter a code. Automatic means that you only enter the phone lock code when a new Sim-card is inserted into it.

Camera shows a black screen

Hi, it sounds if your camera is faulty. 2 questions,(1) is the phone recognising the camera shutter working properly and (2) does the vga camera(front small camera) for the video call. You could probably pick one up from ebay from an old/faulty phone.
hope this helps.

Sony ericsson k800i Not turning on

I had a similar issue, whereby my phone would turn on for 30 secs then the screen would go white and the phone would switch it self off then on.

After a lot of messing around even throwing the phone around the place. I took out the memory card and the phone worked fine. When I put the card back in, the phone started misbehaving again, so I guess the card is knackered.

Sony k800i configuration error

You need to get the Settings for Internet/Wap and MMS from your Network Service Provider. These settings are usually sent as a text msg. When you receive the msg. choose save or install on your phone. Or get the settings directly from their website. The MMS service doesn’t always work between networks.
