Update of built-in weather forecast of htc'diamond mobile phone failed: wrong connection when downloading weather data. Please try again?

You can't update the weather yourself, you can only update it through WIFI. Wifi and gprs can be updated after operation.

The details are as follows: 1. Enter * # * # 4636 # * * and the phone will automatically appear "Test". Click "Phone Information" in the test, and the last line says "Switch DNS check". If DNS is not allowed, you cannot update it. Click "Switch DNS Check" at this time, and it will be displayed as Allow. Ok, this step is completed, and the next step is the second step.

Second, there is a "Set Preferred Network Type" on the "Switch DNS Check". Generally, mobile phones display "CDMA", so non-CDMA mobile phones cannot be updated automatically, and should be changed to "GSM/CDMA auto(PRL)".

According to the above two steps, you can definitely update.
