OnePlus Nord(Avicii) Booting Into Bootloader After Magisk v28 Update: A Troubleshooting Guide

OnePlus Nord (Avicii) users experiencing bootloops after updating to Magisk v28 may find this troubleshooting guide helpful. While Magisk v27 works without issues, upgrading to v28 leads to a reboot into the bootloader, requiring users to flash the stock boot.img to recover. This guide will analyze the situation, explore potential causes, and suggest solutions based on provided log files and device information.
Device Information:
* Device: OnePlus Nord (avicii)
* Android version: 12
* Magisk version name: v28
* Magisk version code: 28001 debug
Analysis:
The provided log files (logcat.log, dmesg.log, proc.mounts.log, console-ramoops-0.log) will be crucial in identifying the root cause of the bootloop. Common issues that can arise after Magisk updates include:
* **Compatibility Issues:** Magisk v28 might have introduced changes that are incompatible with your specific OnePlus Nord (avicii) build or custom ROM.
* **Kernel Panic:** Errors in the kernel, potentially related to Magisk modifications, could lead to a system crash during boot.
* **Corrupted System Files:** During the update process, system files might become corrupted, preventing the device from booting properly.

Troubleshooting Steps:
1. **Revert to Magisk v27:** If possible, flash back the previous working version of Magisk (v27) to determine if the issue is solely related to v28.
2. **Check for Updates:** Ensure your OnePlus Nord (avicii) is running the latest official software update from OnePlus.
3. **Clean Flash:** Consider performing a clean flash of your custom ROM or system images. This can help rule out any potential file corruption.
4. **Review Magisk Log:** Analyze the Magisk log files (located in /data/adb/magisk) for any error messages or warnings that might provide clues.
5. **Community Support:** Reach out to the Magisk development community or OnePlus forums for assistance. Other users may have encountered similar issues and found solutions.

**Disclaimer:** Modifying your device's software can void your warranty and potentially cause damage. Proceed with caution and ensure you have a backup of your data before attempting any advanced troubleshooting steps.
