Resetting N9 Security code, part 2

Alright, now you should have a two big files, one is the firmware itself, the other one is the contents of the eMMC (basically the installed default apps). Like so (for northern Europe device model):
 

Size	Filename
1.6G	DFL61_HARMATTAN_30.2012.07-1.NORTHERNEUROPE_EMMC_NORTHERNEUROPE.bin
1.2G	DFL61_HARMATTAN_30.2012.07-1_PR_LEGACY_001-OEM1-958_ARM.bin

Next turn off the device and make sure it is not plugged into your computer. Then start the flasher:

$ sudo flasher -f \
 -F DFL61_HARMATTAN_30.2012.07-1_PR_LEGACY_001-OEM1-958_ARM.bin \
 -F DFL61_HARMATTAN_30.2012.07-1.NORTHERNEUROPE_EMMC_NORTHERNEUROPE.bin \
 --erase-user-data=secure

Note: For getting rid of the security code (that we don't know) the --erase-user-data=secure option is important, don't forget it.

Flasher should now output something like this:

flasher 3.12.1 (Oct  5 2011) Harmattan
WARNING: This tool is intended for professional use only. Using it may result
in permanently damaging your device or losing the warranty.

Suitable USB interface (bootloader/phonet) not found, waiting...

Flasher is now waiting for the device, so plug in the USB cable now. Flasher should now respond with:

Battery level 89 %, continuing.
Erasing, this may take a while.

It is now erasing the EMMC and as it says, can take a while. Took around 5-10 minutes for me. The white led should blink while it is doing it. After a successful erase operation, the flash should respond with this:

Erase done.
Image SW version DFL61_HARMATTAN_30.2012.07-1_PR_001
Image moslo not present
Image tar skipped
Image config skipped

Battery level 93 %, continuing.

And then continue to the real flashing part, something like this (sizes will vary with different image files):

    image        [state    progress         transfer     flash speed]

Updating SW release
Success

Unplug the USB cable and your N9 should now reboot into a fresh install !

Fresh N9

Enjoy.
