IOS upgrade BUG
I have a iphone XS Max running IOS 13.3.1 right now. When I try to upgrade to 13.3.2 and 13.4.1, it didn't work. It always shows no Interent access and can't verify the upgrade. I tried to trouble shooting steps by steps. But I still can't upgrade it.
First, I delete the upgrade and downloaded again. didn't work
Then, I reset the network setting. didn't work
I also reset the iphone and upgrade it again. didn't work
Finally, I tried to upgrade it through iTunes. didn't work
Anybody can help me on this? Thank you!
