Cannot update iPhone 12 Pro to iOS 14.8

80% isn’t important. At least 5GB free may be required.

To update all of these requirements must be met:

• You must be connected to a Wi-Fi network (and not a personal hotspot) unless it is an iPhone 12 series with an active 5G network connection
• The phone must be charged to at least 50%, and preferably plugged in so it stays above 50% during the update
• The phone must not be in Low Power Mode
• The phone must not be connected through VPN
• The phone cannot be in Airplane mode

If verifying the above here is additional information→Updating iOS: common issues and solutions - Apple Community

Any further luck with the long-form tip that I linked? Usually if everything else is normal there’s either not enough space (it needs 6 GB) or there is an old update download blocking it. To check for this go to Settings/General/iPhone Storage and look for an old update file. If you find one delete it.

I had the same message. Neither one will update. I downloaded iOS 15 but it wouldn’t install so I deleted it because it took up 2.91 GB of space and tried iOS 14.8 and that doesn’t work either and it says it only takes up 281 MB. I don’t know. Apple didn’t give us much communication and it’s all very confusing.

Hi. Any update? Is it ok to jump to ios 15 without installing 14.8? Mine got error downloading too
