My Nook GlowLight 4 Plus is stuck on the boot screen and won’t boot into the system after I flashed a Magisk-patched boot image using *fastboot flash boot*. Holding the power button does nothing at all, and multiple reboot attempts have failed. I’m hoping someone with experience can help me out:

1.*Is this more likely caused by a bad Magisk patch, or an issue during the fastboot flashing process?
​
2.*How do I force the device into fastboot or recovery mode? Holding the power button doesn’t work—are there specific key combinations or alternative methods?
​
3.*If I can get into fastboot, how do I reflash the stock boot image to unbrick it? Where can I find a reliable stock boot image for the Nook GlowLight 4 Plus?
​
4.*If fastboot is inaccessible, are there any deeper unbricking methods (e.g., low-level flashing modes or tools)?

Device: Nook GlowLight 4 Plus
Issue: Stuck on boot screen after flashing Magisk-patched boot via fastboot; holding power button has no effect
Background: Only patched boot with Magisk and flashed via fastboot—no other modifications
Flashing method: *fastboot flash boot magisk_patched.img*
Tried: Only long-pressing power button to reboot (no effect)

Any help or guidance would be greatly appreciated! Thanks in advance.
