I had a problem with the nokia's kernel because i installed an app and it change it. I couldn't erase the new kernel and back to nokia's. so when i turn off the cell phone i couldn't turn it on again because when i do it starts and show me the image of nokia but it turn off by itself and the it starts again and it keeps in the same cicle.

I tried to install the system again but the computer doesn't recognise the phone because it keeps restarting over and over.

can some help me with this?

Been there, done that!

That post should sort it. Done mine when the Power Kernel and user error...er...broke mine. Flashed the latest software on it that way too.

May be best under XP if you can as wouldn't work on my Windows 7 PC.

Thanks for your help, now i have my n900 back
