I have loaded the RX-51_2009SE_10.2010.13-2.VANILLA_PR_EMMC_MR0_ARM.bin file as a partition (removing the first few hexcodes of the file and then using WinHex) and I have found the following differences between the original FAT32 partition in N900 and the updated one: .documents: Many differences in files (User guides) and a new document named "maemo_software_copyright.pdf" .images: no changes .sounds: no changes .videos: only different Nokia_N900.mp4 Mac OS: no changes .n900.ico different autorun.inf different This indicates that OTA update does not update the eMMC contents. On the other hand, I cannot load the ext3 partition or other partitions contained in RX-51_2009SE_10.2010.13-2.VANILLA_PR_EMMC_MR0_ARM.bin. I still need help for this. Cheers.
