It was actually a different post that gave me the idea, but yea - it seems like this was definitely needed. I'm actually surprised no one else made one first - I'm no expert at this stuff, and it wasn't all that hard for me... Anyway, after reading the topic, yea, I can understand the problems you had(not working right after restore). With my tool, worst case, restore RootFS via the Flasher, reboot into my tool, and restore the OptFS via that(no way to restore OptFS via Flasher). BTW, can anyone(who preferably hasn't put much personal info on their N900): 1. Make a backup of RootFS and OptFS with my tool. 2. stick both files into a .tar.gz or .zip file. 3. Upload a copy to megaupload or another host 4. PM me the link. I want to try restoring a unique and different backup; make sure it works fully and properly. Thanks, -Rob
