Apple’s first update to its recently released iPhone software didn’t go so well.
It withdrew the software update Wednesday following widely reported issues that left some unable to use their phone.
After the update, the phones were unable to connect to cellular networks and the fingerprint reader, a security feature, did not work.
“We have received reports of an issue with the iOS 8.0.1 update,” the company said in a statement, adding it was “actively investigating.”
Apple did not have information available on a fix for users who had upgraded and experiencing the issue.
But some users posted on Apple’s online support message boards that their phones were working again after completely resetting the phones using Apple’s iTunes software.
The iOS 8.0 software released last week, shortly before the latest iPhones, the 6 and 6 Plus, became available.
Users have reported other issues, such as problems connecting to the phone using Bluetooth.
