Experiencing a persistent boot loop into fastboot after flashing SuperSU and Magisk v28.0 on your Redmi 6A running LineageOS 19.1? This issue is unfortunately not uncommon. The conflict could stem from improper flash sequences, incompatible Magisk versions, or issues with the SuperSU installation itself.

Thankfully, there are steps you can take to try and resolve this problem. First, ensure your TWRP is fully functional and compatible with your device and Magisk version. Double-check your download sources for Magisk and SuperSU to ensure you have authentic, unmodified files. A common fix involves cleaning the system partition in TWRP before reflashing both Magisk and SuperSU. Ensure you follow the instructions carefully and use the correct flash options. Consider using the Magisk app's uninstaller tool if you suspect a corrupted Magisk installation.

If these steps don't resolve the issue, it may be necessary to revert to a previous known-good system image for your Redmi 6A. Always back up your data before proceeding with any major operation. The LineageOS forums and online XDA communities often have detailed guides and solutions specific to this device and the modifications you're attempting. Remember, troubleshooting requires patience and methodical steps. Don't hesitate to seek guidance from experienced users if you encounter persistent problems.
