Help! Nook GlowLight 4 Plus Stuck on Boot Screen After Flashing Magisk Patched Boot v

[lyzloy]

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.

latest Magisk won't work, you need an earlier version, v24 works.

You can follow this post to solve your current issue.
This would let your device enter fastboot and able to reflash the stock boot.img
