I have the same error, The phone is rooted, Kingo ROOT said Root Succeeded
On my MI2S there is no folder in Data -->
If i try to create a folder then "operation failed". Run Android 5.02 and MIUI 5.4.24
Any suggestions, really need data.
Just updatet from 4.12.5 - FINAL MIUIv5 to 5.1.23 on my MI2s
Everthing works, but not the WLAN. I cant turn it on, BT, data etc. works.
Please help. Do i need to go back to 4.12.5?
