There seems to be no gui for this, but the flasher console utility http://tablets-dev.nokia.com/maemo-d...5.2.2_i386.dmg should work. Code: sudo /usr/bin/flasher-3.5 -F RX-51_2009SE_10.2010.13-2.VANILLA_PR_EMMC_MR0_ARM.bin -f -R Make sure to be in the directory where you downloaded the EMMC Additional info may be found here: http://wiki.maemo.org/Updating_the_t...mware#Mac_OS_X
