There are some steps you should take before you install Apple’s iOS 12.4.8 update on your iPhone, an iPad, or iPad touch.
iOS 12.4.8 is another small maintenance release for devices left behind on iOS 12. It doesn’t have any new features on board. Instead, the software is focused on improving security.
If you’re running iOS 12.4.7 and moving to iOS 12.4.8, you get the shortest list of changes and the smallest download size.
If you’re running an older version of iOS, your iOS 12.4.8 update and download might be a little more substantial thanks to the updates you skipped. They’re baked into your upgrade.
iOS 12.4.8 is an important upgrade, but it’s impossible to predict how your device will react to the move. While some of you might see a performance boost, many others will run into bugs and performance issues that could have a big impact on your day-to-day use.
A little prep work can go a long way toward preventing problems and headaches and that’s why we recommend spending sometime preparing yourself and your device ahead of your upgrade.
- Fully unlocked and compatible with any carrier of choice (e.g. AT&T, T-Mobile, Sprint, Verizon, US-Cellular, Cricket, Metro, etc.).
- The device does not come with headphones or a SIM card. It does include a charger and charging cable that may be generic, in which case it will be UL or Mfi (Made for iPhone) Certified.
- Inspected and guaranteed to have minimal cosmetic damage, which is not noticeable when the device is held at arms length.
- Successfully passed a full diagnostic test which ensures like-new functionality and removal of any prior-user personal information.
- Tested for battery health and guaranteed to have a minimum battery capacity of 80%.
If iOS 12.4.8 starts causing problems, note that you can no longer downgrade to iOS 12.4.7. Apple recently stopped signing on the update.
This means that there’s no way back to older versions of iOS 12 and that means those of you jumping up to iOS 12.4.8 from those versions need to be extremely careful.
We’ve put together plan that takes you through some of the things we do before we install iOS software. These tips will come in handy as you transition your device from whatever it’s currently running to iOS 12.4.8.
Backup Your Data
Backing up your data is arguably the most important thing you'll want to do before installing iOS 12.4.8 on your device.
Data loss issues are rare, but if you store important files on your device it's much better to be safe than sorry. There's always a chance something goes wrong.
Many of you already know how to backup your data, but if you need some help, we've got you covered.
If you don't want to use iCloud, we have a guide that will take you through the backup process using iTunes. If you're running macOS Catalina, you'll need to use Finder, not iTunes.
If you store a lot of data on your device this process could take awhile to complete so you'll need to remain patient. It'll be worth it in the long run.
