After jailbreaking an iOS 15.5 SE (2021) device using Roothide 2.4.5.20, random reboots may occur.
The random restart issue is more severe with Roothide version 2.4.5.18, causing reboots within about 30 minutes of use.
After upgrading to 2.4.5.19 and 2.4.5.20, the problem has improved significantly—sometimes lasting an hour or even several hours.
Attempting to uninstall all jailbreak plugins did not improve the situation.
Uninstalling the jailbreak, reinstalling Roothide, and then re-jailbreaking also failed to resolve the issue.
