Troubleshooting Magisk Root Loss on LG V20 (vs995) with Specific ROM

The LG V20 (vs995) running Android 7.0 Nougat presents a unique challenge when it comes to maintaining root access with Magisk, especially on carrier-based ROMs. User reports indicate specific issues with versions 26-28 of Magisk, experiencing root loss upon interacting with the Magisk Manager app or enabling Wi-Fi. This guide outlines potential troubleshooting steps for this issue, providing insight into the root cause and possible solutions.

**Understanding the Problem:**
On custom ROMs with underlying kernel modifications, Magisk often seamlessly manages root access. However, carrier-based ROMs can introduce incompatibilities due to their more restrictive nature and potential xposed module patches. In this case, root loss seems to be triggered by specific actions within Magisk Manager, posing a challenge for users needing consistent root access.

**Troubleshooting Steps:**

1. **ROM and Kernel Analysis:** The root cause likely lies in the interaction between your specific ROM, the MK2000 kernel, and Magisk versions 26-28.
* **ROM-Specific Modifications:** Carrier-based ROMs often include bespoke modifications to preserve device functionality. These could interfere with Magisk's root management mechanisms.
* **Kernel Patches:** The MK2000 kernel might have specific patches or security measures that conflict with these Magisk versions.

2. **Verify Magisk Installation:** Re-install Magisk version 23.0, ensuring it's properly installed and working as expected. This establishes a baseline for comparison.

3. **Kernel Exploration:**
* **Logcat Examination:** Carefully analyze the logcat output when you experience root loss. Look for any error messages or warnings that might pinpoint the conflict.

4. **Alternative Magisk Versions:**
* **Older Versions:** Explore even older Magisk versions to determine if a specific release introduced the issue.

5. **Modular Approach:**
* **Zygisk:** Although you've ruled it out initially, double-check Zygisk settings and ensure it's not interfering with root management.

* **MicroG Signing:** Verify that your MicroG installation isn't causing the root loss by temporarily disabling it.

**Seeking Solutions:**

* **ROM Developer Contact:** Reach out to the ROM developers for their insights on the specific conflicts and potential solutions. They may have workarounds or know of modified Magisk versions that are compatible with their ROM.
* **XDA Forum:** Forums like XDA Developers often have threads dedicated to specific devices and ROMs, where users share troubleshooting tips and potential fixes.

**Remember:** Before making any significant changes to your device, make sure to back up your data to prevent any accidental loss. Always proceed with caution when experimenting with kernel modules and Magisk versions.

This comprehensive guide provides a roadmap for troubleshooting Magisk root loss on your LG V20 with a carrier-based ROM.
