Well, pressing the 'home' button when I power on isn't doing it for me! I have downloaded the update wizard and installed it (Win XP SP2). I have followed the instructions to the letter. I have tried the N800 in every one of the 4 USB ports on my laptop. I have powered the computer off and on. I have uninstalled the wizard and reinstalled it. I have powered the N800 on and off so many times, I'm worried I'll break the switch! All to no avail.....

When I run the wizard, it says 'checking and downloading updates on the second screen. It appears to do nothing (and, yes, internet connection is rock solid via Cat5). It then suddenly changes to "up to date" (which it isn't - the version on N800 is 4.2007.26-8) and the 'next' button becomes active. (I have also downloaded the latest binary image, but never get any opportunity to use it) I click 'next', and get 'device not found - searching'. That lasts for a couple of minutes then changes to 'Device not found. If you cannot see the USB logo within 5s after switching on, release home button and switch off and try again'. Well, I DO see the USB logo - every friggin' time!

I have tried holding home button; releasing it quickly.....you name it, I've done it! The stupid thing is that I CAN see the N800 as a device in Windows - and can write and read to it as an external 'disk'. The control panel-system-hardware settings show no problems at all. I see two N800 "disks" which are apparently OK. I don't currently have access to a Linux PC, so that's not an option. I've also tried moving SD card from external to internal. NOTHING works - the wizard just absolutely refuses to see the device. ANY help will be very gratefully received!

I remember how I did it. Here:

1. Turn off the N800
2. Connect the USB to the PC.
3. Use your left finger to Hold down the HOME button while pressing down the ON/OFF button with other right finger. ( DO NOT LET GO YOUR FINGERS YET )
4. When your PC found the device, you can let go both fingers.
5. The Update Wizard will begin.

Hope you figure it out. I had this problem until I found out myself.

0: Unplug the charger cable.
1: (As before)
2: (As before)
2.5: Don't forget that the Update Wizard should be running before you continue to step 3
3: Plug in the charger cable. No buttoning needed.
4: N/A
5: (As before)

But i tried both and both didnt work.

I am confused a lot becas as he said, i got the same problem.

Will this be a device fault?

Guys one question for you. Wen i try this as you people said, i got a window opened saying that new hardware found ( which xp does for all devices including ipod and other external devices )
During that process we used to insert a cd and ask the xp to get the drivers needed for it.

Is there anyting tat i need to do like this in this situation ? Becas wen i switch on the nokia during the software upgrade, i get that window along with this. It has even a title NOKIA N800 (UPDATE MODE). When i click the radio button [yes this time only ], then it starts searching and founds nothing. Then on status bar, a problem occured while installing this device.

I am sure this must be noting to do with the nokia software upgrade process right??
Pls someone clarify my doubt.

Or is this the cause for the software upgrade gives the message DEVICE NOT FOUND?

There are no drivers (on CD or otherwise) for you to have to install; they're supposed to be on your system. If Windows successfully found and installed your tablet you *should* be good to go. This sounds like a hardware problem of some sort, either in the USB cable or tablet. I have never seen the "device not found" error when everything was done according to procedure.

I will tell you my little story with "device not found"

At home i have updated many times my n800, but recently i couldn't.
i was desperate thinking that i could have hurt my n800. i reboot it 1000 times
and red all the google about this problem, i tryied mostly everything but i was still getting the message "device not found".

What was the problem??? The update wizard is not working under "windows vista"
( i had recently installed vista instead of xp)
that was the solution to me (it had nothing to do with the way i was pressing the buttons, the problem was windows vista)

Were you able to use compatibility to make it work?

Hmmm. When I tried the update wizard on WinXP it wanted to install a new set of drivers to access the device for the update wizard. I wasn't too surprised about this as I assume that anything connected to usb under WinXP requires some sort of driver (i.e. no raw mode access, this also needs a driver), but it did mean that while installing these new drivers the N800 timed out and booted.

It was already recognised it as a mass-storage device from normal use (which again requires Windows to 'install' drivers - no idea why each different mass storage device needs to have 'new' drivers installed).

I must say that I never got the update wizard to work. Another reason why Windows is rubbish

Would be good to see the source code for the Windows updater as lots of people have troubles with it.
