Frequently Asked Questions (FAQ)
Is it possible to update iPhone via mobile internet (3G/4G/5G)?
Apple officially allows updates over a cellular network only if the update file is less than 200 MB and the corresponding option is enabled in Settings. A full system update (which can be several GB) requires Wi-Fi or a computer. Workarounds exist, but they are complex and don't guarantee stability.
How long does it take to update via cable?
The download time depends on your computer's internet speed and your phone model. Downloading a 5GB file on a fast plan will take 5-10 minutes. The installation process itself typically takes 5-15 minutes on your device. In total, allow about 20-30 minutes.
Do I need to make a backup before updating?
Highly recommended. Although the iTunes/Finder update process is designed to preserve data, any power outage or software error could result in data loss. A backup is your insurance.
What should I do if my phone is running slow after an update?

Old firmware files (.ipsw) can be found online, but they can only be installed while the signing process is in progress.
