Hi guys, I'm new to this thread and new owner of N900

I've just hard-reset my N900 but after reinstalling CSSU-stable version, my hildon desktop won't work at all

it is initially worked after reboot, but after nokia finished loading all apps in desktop, it reverted to Landscape and stuck there

I've installed orientation lock applet but the problem persist

I flash my eMMC using this file [RX-51_2009SE_10.2010.13-2.VANILLA_PR_EMMC_MR0_ARM.bin]
and my rootfs using this:
[RX-51_2009SE_20.2010.36-2_PR_COMBINED_MR0_ARM.bin]

I've also tried using [gconftool-2 -s /apps/osso/hildon-desktop/ui_can_rotate -t bool true], but still cannot go into portrait mode

I also tried to change turning control in Phone, but also cannot turn into portrait

I've also tried to remove battery for 30 seconds but still cannot change into portrait.

and no, my accelerometer is doing just fine

Can anyone please help me, is what I'm doing wrong?

Thank you
