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?
 
Have you tried to factory reset?

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.
 
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?
 
It was just a guess... to dump dmesg:
adb shell su -c 'dmesg' > dmesg.log
 
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

Ok thanks, noted. I will ask him do that and post the dmesg log here for you to check n see.

HI Bro M1cha,

I am Tuck Wai Loh aka Tenchi0205 too...

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.

"<6>[15712.850906] wlan: loading driver v3.2.0.52A

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.

No luck on the wifi after flashed latest miuiandroid rom...

My friend mi2s wifi chip had fried...:cool: made him lost trust on xiaomi phone liao...
 
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.
 
What u didn't tell us is if wlan worked at the beginning or if it was always broken
 
I've got the same problem is unavailable all of a sudden. Both systems down. Will try factory reset,

Edit. Problem solved after disable reanable tdb and reflashing wiui
