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

[Jérôme Bove <jerome@xxxxxxx>]

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
