Member: 1149767 Status: Offline Thanks Meter: 1 | Hello, This is about Chinese iphone wifi n2 (apple clone): I would appreciate if anyone knows how to change setting for Wifi and GMS. My Chinese iphone clone happened to set with WIFI network. Because of this I am unable to dial. Whenever I try to dial I get this message "Dial not allowed". I have even got the engineering mode code that works. However, I could not find any choice for changing network setting for GSM and Wifi. Any feedback will be appreciated. Thanks |

Member: 1198252 Status: Offline Thanks Meter: 0 | I have a feeling that the BaoXing K8900 is one of the phones that has it's Engineer code disabled. I sent it back to the supplier but although my replacement works better it has a problem with the pre-installed java apps like Opera-mini. Even though the phone language is set to English, these apps load with Chinese menus. I can't re-install Opera-mini because you can't overwrite default java apps. As a work around I installed The TeaShark java browser http://teashark.com/ which works fine. I was planning to cut the end off a Nokia DKU-5 cable to make a uart cable but I'm not sure how to find the RX and TX connections on this phone. It only has a standard 5 pin mini-usb plus a 4 way ear phone socket and a 2mm Nokia compatible charger socket. |

you must inspect all pins of 5pin connector as well as handsfree connector for voltages 2,7....2,9volts. Phone must be powered On. if you see this voltages- you can be sure that they are Tx/Rx | |
