Question about Sony Ericsson W800i Cellular Phone

1 Answer

W800i won't turn on

My phone, a black w800i has conked off. It won't power on. Usually if i press the power button for like 2 seconds, it switches on with that bubbly sony walkman theme and sound. Here it just doesn't. Instead it stays blank. There is a sidelight that is glowing though. It's the camera button, it shines the moment i put the battery in.

I had just been using the phone when the screen went all multi coloured with jarry flouroscent lines, green and pink...kinda like a screen that's mucked. the screen hung there and I removed the battery hoping to restart it. This is when it conked off. Any help and soon..would be really really appreciated and I will be truly grateful....serious.

Hello... I am using Sony Ericsson W800i. My problem is 1.When I'm calling someone, the sound is produced from 'speaker', and I want to change the output to 'handset', so I push the 'speaker off'...

Hello and Welcome to FixYa!
Hmm, seems the firmware is getting buggy, as its a common thing in SE phones, but the solution is also simple as 123, all you should have is the USB Data Cable of your phone, if you have it then just download the SE Update utility for your phone, I've attached the link below. Download it, install it and run the application. The wizard will guide you on how and when to connect the phone. I'll also recommend you to see the 'Before you Begin" section on that page, as you will loose everything on the phone. It will be as in "Out of the Box condition".
If you are still having problems, do ask me. I'm here to help.
If you think I was of help, your token of appreciation in the form of rating will be esteemed.
Concerned, Nooh

P.S: W800i Software Update

My Sony Ericsson W800i gets held whenever I press the walkman button

That means that the firmware for the walkman is corrupt for whatever reason. To rectify this you must reinstall the firmware. If your phone is in warranty then I would recommend that you get it done from the service center of Sony Ericsson.

Unlock sony ericsson w800i

Yes Just purchase the code from then follow the instructions as follows:
Warning : Do not enter any wrong unlock codes on your Sony Ericsson W800i mobile phones. If you enter over a certain amount of wrong unlock codes on your Sony Ericsson W800i mobile phone, your phone may get hard locked and sometimes become unusable.
1 - Switch ON your Sony Ericsson W800i 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 W800i 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.
