If we extract the files in the self-extractor (I've downloaded the Windows version and extracted with Winrar) we can see that there are the following files: EMMC.bin (I suppose that this file correspond to RX-51_2009SE_10.2010.13-2.VANILLA_PR_EMMC_MR0_ARM.bin of the Maemo package) flasher.bat flasher.exe msi_package_version.exe Nokia_Connectivity_Cable_Driver.exe RX-71.bin (I suppose that this file correspond to RX-51_2009SE_3.2010.02-8_PR_COMBINED_MR0_ARM.bin of the Maemo Package) These are only my thoughts, I'm not sure about it.
