The Samsung Galaxy S22 is a powerful device, but users seeking root access through KernelSU have reported encountering bootloops during the installation process. This guide aims to help troubleshoot these issues and get your S22 running smoothly with root privileges.

**Understanding the Problem:**
When attempting to flash a patched boot image using KernelSU, a bootloop indicates that the modified boot process prevents your device from starting correctly. This can stem from various factors, including:

* **Incompatibility:** KernelSU might not fully support your specific device model, firmware version, or kernel build.
* **Patching Errors:** Issues during the patching process can lead to a corrupted boot image.
* **Flashing Issues:** Incorrectly flashing the patched boot image through Odin can cause system instability.

**Troubleshooting Steps:**

1. **Verify Firmware Compatibility:** Ensure your Galaxy S22 runs on the latest official firmware (in your case, S901BXXUDEXK5). Confirm compatibility between your KernelSU version (1.0.2) and this firmware. Refer to the official KernelSU documentation and GitHub repository for supported device models and firmware versions. If incompatibility exists, you might need to wait for updated KernelSU releases.
2. **Double-Check Patching Process:** Carefully review the steps for patching your boot image using KernelSU. Ensure you extract, patch, and recompress the boot image correctly. If you used a downloaded boot image, make sure it's compatible with your device and firmware.
3. **Reflash Original Boot Image:** If you suspect a patching error, try flashing your original, unpatched boot image back to your device using Odin. This may help isolate the issue and rule out any corruption caused during the patching process.
4. **Try Alternative Boot Images:** While KernelsU provides pre-built boot images, you can explore alternative sources for boot images specifically designed for your device model and kernel version. This might provide a workaround if the included KernelSU image experiences compatibility issues.
5. **Secure Download Sources:** Always download KernelSU and boot images from trusted sources to ensure they are not corrupted or tampered with.
6. **Seek Support:** If you've exhausted these troubleshooting steps, consider reaching out to the KernelSU developer community for assistance. Provide detailed information about your device, firmware, KernelSU version, and steps you've taken, so they can help pinpoint the problem.

**Note:** Always back up your data before making any significant changes to your device's firmware or system files.
