thanks for your patience Mosen but imust be doing lots of things wrong. I get to the point of "suitable device not found...", and then is when I connect the N900 to the laptop and the phone goes into that opaque screen with the usb icon in the top right corner as instructed but nothing else happens after. phone does do anything else and the most annoying is that command prompt screen doesn't allow me to write anything else. the prompt is there blinking but that's all. very frustrating. do I have to switch on the phone after plugging it to the usb? and also those RescueOS images that you posted (thanks sincerely for all your time and patience)... do I have to save tham all in the same forlder as the rest of files? or only the rescue 1.3? none? hmmm I cant find what am I doing wrong
