Samsung Galaxy S20 Bootloop Issue with KernelSU Installation: Troubleshooting Tips

The Samsung Galaxy S20, while a powerful device, can present unique challenges when attempting to install custom software like KernelSU. This issue report details a user experiencing a persistent bootloop after installing KernelSU through AnyKernel following a manual kernel build. The user has modified the kernel as instructed on the KernelSU homepage, disabling Samsung Knox-related settings as suggested in the provided commit link (https://github.com/Mesa-Labs-Archive/android_kernel_samsung_sm7325/commit/7569eb2c1549a98f0edef3c2d22d92d2211aaa1d). Despite these efforts, the phone gets stuck on the Samsung logo, preventing further boot progression.

This bootloop issue can be a symptom of several problems.

* **Kernel Configuration Conflicts:**
Even with Knox settings disabled, other kernel configurations could be clashing with the KernelSU installation.
* **AnyKernel Issues:** There might be compatibility problems between AnyKernel and the specific Galaxy S20 kernel or Android version.
* **Incomplete Kernel Build:** An error during the kernel build process could result in an unstable kernel that causes boot issues.
* **OneUI Specific Conflicts:** The OneUI overlay might introduce unexpected conflicts with the modified kernel and KernelSU.

**Troubleshooting Steps**

1. **Double-Check Kernel Build:** Ensure the kernel build was completed successfully without any error messages. Verify all necessary files were generated.
2. **Review Kernel Configuration:** Scrutinize the kernel configuration for any potential conflicts or misconfigurations related to device drivers, security features, or system services.
3. **Try Alternate Installation Method:** Experiment with different installation methods for KernelSU, such as manual flashing through TWRP recovery or using a different flashing tool.
4. **Seek Community Support:** Engage with the KernelSU community or Android developer forums for potential solutions specific to the Galaxy S20 and OneUI.
5. **Revert to Stock Kernel:** As a last resort, revert to the stock kernel to rule out any hardware or software incompatibilities caused by the modified kernel.
