Thanks for your suggestion, but this forum did not work for me. I need to reflash the emmc. I could always flash it before without problems, but since I modified "RX-51_2009SE_10.2010.13-2.VANILLA_PR_EMMC_MR0_ARM3gib.bin" I can not do it. Can anyone tell me the steps in LINUX.

NOW I did get I ubuntu LiveCD. Please can you said the best way for this?
Here I believe to get the solution

any suggestions to make my n900 a home s factory?

I need to get this:

By default the internal eMMC flash card on the N900 (/dev/mmcblk0) is partitioned as follows:

27 GiB VFAT MyDocs partition on /dev/mmcblk0p1. When Maemo is booted, this is mounted on /home/user/MyDocs, however it is unmounted and exposed when the N900 is connected to a PC in mass storage mode

2 GiB /home partition on /dev/mmcblk0p2. This also contains the /opt folder (mounted on /home/opt) where optified apps are stored

768 MiB swap partition /dev/mmcblk0p3
