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
