[HTC Pico (Explorer)] @rcane:
So here is the problem. First i flashed sense4 build#6 by derefas. Then used build#7 kernel with build#6 ramdisk and flash. Build#6 booted!! everything works fine except wi-fi and hotspot. I tried fixing permission but no luck. Here is the Logcat:

I faced same problem with cute_prince kernel source. I compiled kernel and try to flash on build#6 or latest cm9 with appropriate ramdisk everything works fine except wi-fi and hotspot. I am not able to get logcat but i think it would be same as above. So plz if anybody could help me.
