Issues with N900 (keyboard backlight, leds, jack sense)

Hi all !
My N900 has some issues and I just don't want to send it to Nokia Center.
I tried to flash it (emmc + rootfs)
Problems are :
- Keyboard backlight and the (multicolor) led just doesn't light.
Here is the result of some commands (running as root):

Nokia-N900:~# ls /sys/class/leds/
twl4030:vibrator

Nokia-N900:~# rmmod leds_lp5523
Nokia-N900:~# modprobe leds_lp5523
Nokia-N900:~# dmesg
[19776.520812] lp5523: probe of 2-0032 failed with error -121

- When I put a jack headphone in the phone, it's not detected by the phone
and I still hear sound by speakers. The event is detected by dmesg
If i connect and disconnect the headphones:

Nokia-N900:~# dmesg
[19920.847106] headphone (GPIO 177) is now connected
[19925.729705] headphone (GPIO 177) is now disconnected

Can you help me please ?
I'm desesperate

If you've already tried flashing it, I guess that means you have hardware issues.

Which version of the rootfs and mmc did you flash?

Also, when you connect the headphone, do you see the headphone logo appear at the top?

I used RX-51_2009SE_10.2010.13-2.VANILLA_PR_EMMC_MR0_ARM.bin and
RX-51_2009SE_20.2010.36-2_PR_COMBINED_MR0_ARM.bin
There isn't any headphone logo when I connect the headphone.

If it's an hardware issue i'll have to send it to Nokia Center. What will
they do ? Give a new one / Fix mine / Give my money back ? How long will it
take ?

Thx
Jérôme
