Old iPhones will become bricks if they don’t update today

From tomorrow, iPhone and iPad models from 2012 and earlier, if not updated, cannot be used because the GPS weekly counter is too limited to count.

According to Apple announced in the past month, old devices from iPhone 5 and iPad 4 and earlier, if not updated before tomorrow, will have GPS problems and cannot display the correct date and time. Also, if not updated, users will not be able to access Apple services such as mail, iCloud …

With this “Y2K GPS” issue, Apple decided to release another update to support users.

Users of these devices need to update their software to the latest version before November 3. These devices will be updated to iOS version 9.3.6 or iOS 10.3.4.

To check, users go to Settings > General settings > About and see the available iOS version. If the current version is not 10.3.4 or 9.3.6, the user should update it.

Without updating OTA versions before November 3, users will be required to download new and upgraded versions of iOS on their computer. By then, the affected older iPhone models will not be able to connect to the Internet.

Experts explain this is considered a Y2K event about GPS. This event affects all devices that support GPS.

GPS systems generally use a 10-bit variable week counter. Therefore, they can only record values ​​from 0 to 1,023. When the device reaches the week 1,024, if not reprogrammed, it will not be able to start or skip the week counter. This makes it impossible to use GPS and time data.

The first week counter was started on January 6, 1980. By August 21, 1999, the first week counter was full and needed to be reset. That is considered the end of the first “GPS era”. The second week counter that ended in April and November 3 is the deadline to use supported older counters.
