Fix for TWRP Users

While it is always recommended to boot the TWRP rather than directly flashing it, however, there are a few TWRP/devices that don’t support temporary boot. So if you use the fastboot boot twrp.img, you’ll get the Failed to load/authenticate boot image error message. In such cases, your only way out is to directly flash the TWRP file via fastboot flash recovery twrp.img and then check out the results.

Fix for Magisk Users

If you are getting this error message when trying to flash the patched boot.img, then the culprit might infact be the boot.img file itself. So to fix this issue, you just need to flash the stock boot.img. So download the stock firmware for your device [the same version which is currently installed, you could verify the same from the Build Number].

Then boot your device to Fastboot Mode and execute the fastboot flash boot boot.img to flash the stock boot file. This should fix the underlying issue. Once that is done, you could now refer to our guide to root your device via Magisk.
