The first method is a pretty straightforward one, you only need to flash the Magisk ZIP via TWRP and your device stands rooted. However, not every device has a working TWRP. Likewise, some users prefer to keep a safe distance from flashing this custom recovery due to the complexity involved (especially after the A/B vs A partition change). All these reasons combined, users generally flock over to the second method. This involves extracting the boot.img from the stock firmware, patch it via Magisk and flash it via Fastboot Commands. While it involves quite a few steps but is a tried and tested method. With that said, it isn’t free from its fair share of issues as well. One among them is when the user ends up in a bootloop after flashing the magisk_patched.img file. If you are also getting bugged with this issue, then this guide is here to help you out.

The Reason for Bootloop after flashing Magisk Patched Boot.img File
So why does this issue arises in the first place? Well, it happens when the boot partition on your device gets corrupted. And one of the major reasons for the same is when you have patched and flashed the incorrect build of boot.img.

In other words, you should download the same firmware version that is currently installed onto your device. If you don’t do so but rather try out the rooting using an older or newer build of the stock firmware, then the issue is imminently bound to happen. So with this, you would have got a perfect idea regarding the reason for this issue. Let’s now check out the steps to fix the bootloop after flashing the magisk_patched.img file.
