right you dont install anything. you get the flasher running with the commands.

when it says waiting for suitable device. you run that program from the bin file and create a .inf file for your nokia N900 (PC Suite Mode),

after that you find the N900 Phone Parent and update the driver and direct it to the inf file folder. and then it will work.

I dont mind doing this via team viewer. and am in the UK. ive broken it down into paragraphs to make it more clear. I know am not the best person to describe things, just to do it lol
