What does cold flashing have to do with running a command with higher privileges? @polomarko " 'sudo' on linux" -eq " 'run as administrator' on windows", so something you already have done, as flasher runs only with admin privileges on Win. Just go ahead and follow rainisto's path. Maybe try a warm flash directly after the cold flash (idk, but heard/read smth like that). And one more thing: When trying to flash a cmt from another sw release you need to give the ape-algo from current release, so your command should look like: flasher -a DFL61_HARMATTAN_40.2012.21-3_PR_LEGACY_009-OEM1-958_ARM.bin -F DFL61_HARMATTAN_40.2012.21-3_PR_LEGACY_001-OEM1-958_ARM.bin --flash-only=cmt -f Otherwise it is pointless, as it would be a normal flashing operation...
