Flashing OS2008 With Mac OS X (Console)

From Internet Tablet Talk

These steps cover flashing an N800 or N810 with OS X using the Terminal. For a GUI method, please see aflegg's 770Flasher (yes, 770Flasher will work fine for flashing an N800 or N810).

1. Create a new folder on your desktop, name it "n800_upgrade".
2. If you have an N800, go to http://tablets-dev.nokia.com/nokia_N800.php, if you have an N810, go to http://tablets-dev.nokia.com/nokia_N810.php, and enter your WLAN MAC address into the field (this is located on a sticker behind the battery panel).
3. Download the latest firmware release.
4. Move the downloaded firmware into the n800_upgrade folder.
5. Go to http://tablets-dev.nokia.com/d3.php and download the flasher-2.0.macosx.
   The flasher-2.0.macosx may actually download as "flasher-2.0.macosx, attachment" if it does, then rename it to "flasher-2.0.macosx".
6. Move the flasher-2.0.macosx into the n800_upgrade folder.
7. Now, open up the Terminal (it's in /Applications/Utilities/) and type:
   It will ask you for an administrator password after the second command, enter it.

   cd ~/Desktop/n800_upgrade
   sudo chmod 755 ./flasher-2.0.macosx

8. Now turn off your device (make sure you unplug the charger or else the device wont power down completely, you can plug the device back into power once it starts flashing) and plug in the USB cable to a port on the computer and the port on your device.
9. Depending on which device you have, you'll need to type one of the following:
   • If you have an N800, type this (all on one line!):

   sudo ./flasher-2.0.macosx -F
     ./RX-34_2008SE_2.2007.51-3_PR_COMBINED_MR0_ARM.bin -f -R

• If you have an N810, type this (all on one line!):

   sudo ./flasher-2.0.macosx -F
     ./RX-44_2008SE_2.2007.51-3_PR_COMBINED_MR0_ARM.bin -f -R

10. It will say:

   Suitable USB device not found, waiting

11. Take your device, and hold down the Home/Swap button (looks like a little house on the N800, and two overlapping rectangles on the N810), and while holding down the Home/Swap button press the power button to turn it on.
    If it doesn't doesn't boot and start flashing, make sure the USB cable is plugged in.
12. It should start flashing and then reboot.
13. You can remove the USB cable after it has booted to a normal desktop (just make sure to eject any cards that may have mounted on your Mac).
