What if the 5830 Chinese calendar can't be updated?

Don't use WIFI to update, use 3G network to update, sometimes 3G network doesn't work, you can choose 2G network, and it will definitely be updated. I've tested it many times. Here's the process. First, don't connect to WIFI, use mobile phone traffic to update (3G). If not, you can open Settings-Wireless and Internet-Mobile Network-Access Point Name -WAP on the desktop.

Then update it and it will be ok. You can try. I hope it can be adopted.
