Hola,
hablando con el chino me ha dicho que el problema del wifi se soluciona así:
1 . download this fix
http://ge.tt/8GodLxb/v/0
extract and copy to the SD on your phone
2 . Install a root file browser app such as ES File Explorer
3 . MAKE SURE root browsing privileges are enabled in the app. Some root file
browsers will have it enabled by default, others such as ES File Explorer require
you to go into settings and enable
4 . Navigate to \\data\\nvram\\APCFG\\APRDEBed
5 . Rename the file WIFI to WIFI.ori
6 . Rename WIFI_CUSTOM to WIFI_CUSTOM.ori
7 . Copy the previously downloaded and extracted files to \\data\\nvram\\APCFG
\\APRDEBed
8 . Reset the phone
OK¿? is very easy
Espero que os sirva.
