I have the Huawei M835 and I can't change the time. It gives me the option but it isn't highlighted to click it. It has Automatic checked but doesn't give me the option to de-check it.
Afaik, you can't. If the time is wrong try turning airplane mode on for a couple minutes. It should correct when you turn airplane mode back off.
Verry simple my friend. Put you're phone into airplane mode The go into time and date settings and you will be able to unselect network provided settings. Enjoy!
