Some users are reporting problems during the iOS 8 installation process.
You will get a “Checking For Update” message on the screen. When does it happen? When you try installing iOS 8.0 as an OTA update from your iOS device.
We discovered the same problem on our iPhone device. Here’s what happened:
First, we connected our device to a WiFi Internet connection. Next, we unlocked the device, navigated to the Settings option. In here, we went to General -> Software Update.
The Never Disappearing Message: Checking For Update
Our task is done here. Now, the iPhone connects to the Apple server and looks for the new iOS 8 update. What happened next? Apple iPhone was still looking for an update with a message “Checking For Update” that stood right there.
For more than two hours.
Many users have reported that they have waited over 4 hours to get past this message.
After realizing that “Checking For Update” message will never disappear, we did the next logical thing: we rebooted and performed a hard reset on our device.
Did that help? We were still stuck with the same error message and nothing really fixed this issue.
So what’s the solution? The only solution we can recommend you is to install iOS 8 using other methods. You realize that we have several ways to get iOS 8 on our iPhones, iPads, and iPod Touches… right?
OTA (the above method) is just one of the ways. We quickly downloaded IPSW files of iOS 8.0 final version and used iTunes to download and install the update (see this method). This did take our valuable time, but it is the most convenient way to safely put iOS 8 firmware on our Apple devices.
We believe the message appears only for two reasons: first, Apple’s server has received too many requests that we were forced to “wait” in the queue. Second, our Internet connection speed was super-slow. We never got the opportunity to try Software Update via 4G/3G yet, and we only used WiFi connection with 50 Kb/sec speed.
Maybe slow network connection is the reason we received “Checking For Update” message? Nonetheless, our friend Tim says that he was able to get rid of this message by rebooting the device multiple times and making absolutely sure that no files were downloading in the background.
There are no strict rules on what works and what doesn’t. So try rebooting a couple of times if you prefer updating iOS 8 via OTA. If that works, great. If not, we always have the option to directly update to iOS 8.0 using the iTunes player.
