[HELP] Sensors undetected

Hi Everybody !

Today i ported MIUI V7 to my Archos 45 Helium 4G from the Ktouch 3
To port it, i took the boot.img of a MIUIv4 ROM from the Archos, and edited the BOOTCLASSPATH row

But now, my sensors doesn't work anymore, i tried to replace libs and a lot of thing, nothing works
I saw that init.qcom.sensor.sh was missing to my /system/etc directory, i downloaded it but doesn't help

Please, what can I do to make my sensors work ?

Thanks in advance
