    The wifi toggle also grey in colur and cant be activated. Connected to 3G also cant tether the 3G out as hotspot.

    So does this mean the wifi module/chip on the Mi2S is dead?

    Yes, he did (the phone is belong to my friend one, my one thanks God is still working)

    He also downloaded the original miui v5 rom from the Chinese forum side and flash in into the phone also no luck.
     
  4. Maybe his efs are broken.(these partitions do contain imei and mac addresses).
    EDIT: if you give me a dmesg dump I can tell u what's the problem, wlan or efs.

    ?
    If efs broken then nothing can do already? But he can make call n received calls, if imei gone, that is impossible right?
    How to get the dmesg dump?
     
  6. It was just a guess... to dump dmesg:
    adb shell su -c 'dmesg' > dmesg.log

    type this "adb shell su -c 'dmesg' > dmesg.log" in Android Terminal Emulator?

    then where to copy the dmesg.log? :D
     
  8. No on pc with adb enabled. If u want to use terminal emulator use these command
    su -c dmesg > /sdcard/dmesg.log

    U'll find the log on sdcard then

    You didn't upload the log, just saying.
    The forums wont allow you to upload a *.log file. You should rename to extension to .txt and reupload.

  14. "<6>[15712.850906] wlan: loading driver v3.2.0.52A
    <3>[15712.850967] wlan: [1883:F :HDD] hdd_driver_init: WLAN device not found!!
    <3>[15712.850997] wlan: driver load failure"
    Which rom do u have installed? If the kernel is correct it seems your wlan device is dead.

    EDIT: I would try to flash latest miuiandroid rom because it contains latest kernel and modem. If that doesn't work ur wifi device is really dead and u should send your phone to repair.

    Sucks, perhaps it might be worth sending the device to the seller?
    Most sellers seem to offer warranty.

    We bought it in China on the shopping complex telco shop...and we are in Malaysia....I don't think got warranty...

    He will have a damn expensive alarm and gaming device...and he lost hope on Xiaomi product already.
     
  18. What u didn't tell us is if wlan worked at the beginning or if it was always broken
