thanks a lot. what i did is i installed the .exe file (48kb) and put the below code in the maemo flasher 3.5 command but fialed to recognize. Any suggestion.

"md5sum RX-51_2009SE_1.2009.41-1.VANILLA_PR_EMMC_MR0_ARM.bin"

so the command appears like this "c:\program files\maemo\flasher-3.5>md5sum RX-51_2009SE_1.2009.41-1.VANILLA_PR_EMMC_MR0_ARM.bin"

yes all the files are same and from the same source you linked above. .
