Jailbreaking is the process of removing the limitations imposed by manufacturers or carriers to expand the restricted permissions on a device. How are the kernel-level security measures disabled in this method, what tools are used, and what are the potential risks? Additionally, how does it affect user experience? In your opinion, what are the advantages and disadvantages of jailbreaking?

Jailbreaking is a way to "hack" an iOS device by gaining root access and the ability to install uncertified apps. In practice, I've used checkra1n and Unc0ver, which only work with specific iOS versions, so the first thing I do is check compatibility and make a full backup in iTunes/iCloud. After bypassing the code signature, you can install Cydia or Sileo, where tweaks that extend functionality (like volume control in widgets or disabling ads in system apps) are located.
The main advice is to jailbreak only if you truly need these features and are willing to accept the risks: voiding your warranty, potential issues after OTA updates, and increased vulnerability to malware. For Android devices, I usually prefer custom ROMs (LineageOS, Pixel Experience)—the process is similar, but open-source code and an active community reduce the chance of "bricking" your phone. If you decide to jailbreak, keep your device in "offline" mode, avoid public Wi-Fi, and only update using trusted repositories afterward.
Jailbreaking an iOS device is very similar to rooting an Android device; since iOS is more closed-off, security vulnerabilities pose a greater risk, whereas rooting on Android is generally easier with open-source tools. Ultimately, the balance between ease of use and risk differs between these two platforms.
