7 Use fruit for some time, has been updated to update, not too concerned about ios13 6.4 beta release, I just left a friend when the mice, and that is a big change, it is also to experience under the new ios13 beta.
Many ways to view the online tutorial, and now has been used Ace assistant, it is easy to upgrade to ios13. Here's my iPhone upgrade 7p to be a record.
1, Elsevier assistant download the corresponding mobile version of ios13 beta firmware, the direct use of this upgrade is possible, listening to friends that do not affect the data. But just to be safe, no matter how used, data backed up under as well.
2, read online tutorials, said the latest test version upgrade mac can upgrade it more convenient to decisively upgrade. I upgrade this air for half an hour more.
3, my phone is an upgrade from ios12.3.1, above all, iTunes data backup, mac about half an hour to back up this end, if the win the backup do not know what the reason is slower, and the relationship may be a bar.
4, the new version of mac installed, connect the phone to find finder, similar with iTunes, the left column there will be a phone icon, click on it below, click on check for update by selecting options Ace click to download the firmware upgrade under mac . (Before the upgrade, ensuring the best backup insurance purposes)
5, during a password is entered, on the restart after the upgrade, may restart several times during patiently waiting, I was directly asleep, the next day to see the upgrade is completed.
This whole process, need some time, about 30 minutes or so. The only problem after the upgrade, part of the app will be some compatibility issues, not other problems. For individuals, the only bright spot is dark bar, adjust the volume icon on my little effect. Baidu everyone else when it comes to the question, I do not care too much, life is hot and has yet to be tested.

b, for safety reasons, it is recommended after the backup upgrade.
