Hi, I recently had a problem on my N900, all of the sudden it rebooted and then got a message on screen saying: Installing Software Update. Please do not interrupt, and then it keeps rebooting, so I figured out I needed to flash the device, I already have all the tools required, the problem is that I cannot get the phone into usb mode, I tried pressingand holding the U key and connecting the usb, but the usb icon is not showing up in the device, so I cannot flash it, I have tried on Windows 7, Windows XP (both 32bits) and on ubuntu and still cannot get it to work, any idea or suggestion of what to do? (and return it wont work for me cause I didnt bough it on my country) Thanks

i thought it was supposed to be completely off when you ran the flasher? You turn if off and connect it when it says searching for suitable device.

did you try all of this? Just replace the firmware name with the one you are flashing to.

I have tried all of that, but the problem is that when I connect my phone its not recognized by the computer, or backwards, I know that I should see the usb icon on the top of the screen, but is not doing it, it just start charging, I am pressing and holding the "U" key and connecting the usb, but its just not getting into flashing mode

charge the battery to full and try again

I tried fully charged, but when I connect it to the usb with the U key hold it just starts charging, and after a while it starts showing the same message on screen

The battery probably isn't charging unless the phone is booted up and happy.. it just looks like it.. seriously..

Best bet is to find someone with an N900, X6, 5800 or 5230 handset and use theirs to charge your battery.. after that, it should respond to the press and hold u trick!

yeah thats a good call, I will give it a try and let you know if that works, thank you!
