It Appears That My Nook HD has been stuck in a recovery loop and cannot get out of it. Apparently my /bootdata is missing also. Anyone advice one how and why it is stuck in a recovery loop.

[Q] Cannot Boot into Recovery, Android O.S is Messed Up

Hi,
The other day, I flashed a new ROM (after clearing everything) and it has messed up my entire device. My device gets stuck at the android logo and stays there forever when booting into Android. I cannot boot into recovery mode, it just gets stuck at "Google".
I also cannot boot into recovery mode using Nexus 7 toolkit because it requires my device to be booted, which is impossible.
Anyone know how to fix this?
Thanks

For some reason, every time I try to boot into recovery, either through app or munual restart, my phone gets stuck in a boot loop and I have to reflash to get out of the loop.

What have you done to get your phone into bootloop(flashed rom?)

My SM-T515 is stuck on the TWRP logo and i can't do anything.

So, I wanted to root my device using magisk but i failed and tried to install TWRP. After installing it, I restarted my device and tried to get into TWRP only to get stuck in the logo screen. All I can do is restart the device, I can't get into download mode and stuff like that, nothing works at all.
I left the tablet overnight and it is still stuck on the logo screen, any help?
EDIT: I have managed to break out of the boot loop by following petapen's instructions inhttps://forum.xda-developers.com/galaxy-tab-a/how-to/galaxy-tab-sm-t510-stuck-twrp-3-3-1-0-t4075359! Problem solved!
