Five days after Apple began recom
mending the installation of iOS 18.4.1, the iPhone operating system update, a problem with the phone was discovered. In other instances, it has turned into a so-called "brick phone" that is completely unusable.
Phone Arena, an IT media outlet, stated on the 22nd that "it has been claimed that the iPhone has become a 'brick' since the installation of iOS 18.4.1." The user reports that after installing the update, the device's unique identification number (IMEI) is no longer recognizable.
He also went to the Apple service center after the issue occurred, but the representative there told him that he would have to replace the main board, which would have cost 80% of the iPhone's price. As a result, he was unable to use his phone.
When the iPhone's IMEI or modem firmware information is not searched, it usually means that there is an issue with the modem that is mounted on the motherboard. Disassembling the main board of the modem is necessary to fix this issue.
"It seems unlikely that the iOS update caused problems with the modem, but there were cases where some iPads became 'bricks' after installing the previous iPadOS update," Phone Arena said. "The modem of the device that caused the problem may have been defective, and the update may have caused this problem."
Earlier in September last year, Apple stopped distributing updates due to a "brick phenomenon" on iPads 11 and 13 equipped with M4 chipsets after distributing iPadOS 18. The domestic iPhone-related community is also raising problems such as the iPhone's heat generation getting worse or the battery consumption getting faster after the installation of iOS 18.4.1.
von Arena stated, "In addition to the cases, there are people who complain that they have experienced similar problems." "For the time being, it would be better to disable automatic updates."
Apple began releasing iOS 18.4.1, the most recent iteration of the iPhone operating system, on the 17th. Apple has advised a speedy OS installation by addressing security flaws and bugs.
Samsung Electronics also updated its One UI in the interim; however, due to issues like some users' lock screens not being released, the update was halted for two weeks and only recently resumed.
