Friend,

When you hit "Enter" on your computer's keyboard to initiate the command:

1. Is your N900 turned off?
2. Does it contain enough charged/is the battery charged well?
3. Is the N900's keyboard slid out open?
4. Did you press and hold the "U" key (letter "U") on the N900's keyboard before hitting Enter on your computer keyboard to initiate the command?
5. Is your Nokia N900 plugged to your computer to the front USB port (or a USB hub/extension)? Or is it plugged in to your main USB ports (yung mga USB ports sa likod ng CPU if you're using a desktop computer)?
6. Can you share to us a screenshot of your Windows Explorer showing the contents of "flasher-3.5" folder? I just need to check something just to be sure.

EDIT: By the way I appreciate you reading the threads...pero may Wiki Page din for Flashing the N900. Nabasa mo ba yun? May YouTube video din dun na puwede mong panoorin. Eto, Ultra-Newbie Guide for Flashing the N900: http://www.youtube.com/watch?v=O54KdLvTA2U

Selling N900 for E7? Naku sayang ang pera mo, just my opinion. May inaabangan ang mga members dito na medyo "more updated" version of the N900 (will be called N9 or N950), you might want to wait for that first. On second thought...well depende rin kung mapanghihinayangan mo or hindi. It will depend kung ano ang hilig mong gawin sa isang gadget/device. As for me, since I got the Nokia N900 I really enjoyed it and I plan to stay with it for a year or two.
