Flasher Troubleshooting

ℹ️ The N9 is very hard to actually brick. As long as sudo flasher -i sees the device in flash mode (volume-up + USB), you can recover it.

Device won’t boot after a flash

The combined flash command (-F OS -F eMMC --flash-only=mmc) sometimes only flashes the eMMC portion. If your device is stuck on the Nokia logo or boot-looping, try flashing the OS image on its own first:

sudo flasher -f -F ./images/DFL61_HARMATTAN_40.2012.21-3_PR_LEGACY_001-OEM1-958_ARM.bin

File: DFL61_HARMATTAN_40.2012.21-3_PR_LEGACY_001-OEM1-958_ARM.bin

If you also need to restore eMMC content, flash that separately afterwards:

sudo flasher -f -F ./images/E7FEB593_DFL61_HARMATTAN_40.2012.13-7.UKIRELAND_EMMC_UKIRELAND.bin --flash-only=mmc

File: E7FEB593_DFL61_HARMATTAN_40.2012.13-7.UKIRELAND_EMMC_UKIRELAND.bin

RD mode and flags

R&D mode unlocks low-level access. Enable it with:

sudo flasher --enable-rd-mode

Useful flags:

# Allow power key to force-reboot
sudo flasher --enable-rd-mode --set-rd-flags=force-power-key

# Disable the watchdog auto-reboot
sudo flasher --enable-rd-mode --set-rd-flags=no-lifeguard-reset

Disabling RD mode

If you enabled RD mode with no flags:

sudo flasher --disable-rd-mode

If you set flags, you must clear them explicitly when disabling, or they’ll stick:

sudo flasher --disable-rd-mode --clear-rd-flags=no-lifeguard-reset

Multiple flags can be cleared at once:

sudo flasher --disable-rd-mode --clear-rd-flags=no-lifeguard-reset,force-power-key

Other commands

# Reboot the device
sudo flasher --reboot
