Failed to update the built-in weather forecast on htc'diamond mobile phone: A connection error occurred when downloading weather data. Please try again?

The built-in weather cannot be updated and can only be updated through WIFI. After operation, both wifi and gprs can be updated.

The details are as follows: 1. Enter *#*#4636#*#* on the phone dial key. The phone will automatically display "Test". In the test, click "Mobile Information", and there is "Switch DNS Check" on the last line. If dns not allowed is displayed, it cannot be updated. At this time, click "Switch DNS Check" and it will be displayed as allowed. Okay, this step is completed, and then proceed to the second step.

Second, there is a "Set the preferred network type" above "Switch DNS Check". Generally, mobile phones display "CDMA", so non-CDMA mobile phones cannot update automatically. At this time, it should be changed to "GSM" /CDMA auto(PRL)",

Follow the above two steps, you can definitely update.
