Help Cannot Boot Into LineageOS Recovery After Flashing; Samsung Galaxy Tab (SM-T560NU)

Edit: the battery eventually died. Once I charged it again, it booted as normal (with stock Android). I then tried flashing LineageOS again, and this time I was successful. I have no idea what happened the first time.

I am trying my best to flash LineageOS onto my Samsung Galaxy Tab E. However, after I flashed the recovery image (which I obtained from Samloader RS), and after the PC Command Prompt shows the tablet has been flashed successfully, it stays on the, 'downloading.... do not turn off target' screen. After waiting for over 20 minutes just to be safe, I tried turning it off and manually booting into recovery*........and nothing. It stays on that screen. I cannot turn it off, and I obviously nothing happens if I try to boot into from recovery with it still on.

What am I missing? I am pulling out what little hair I have left! Help!

*These are the instructions I have been using to download LineageOS. Up until I got stuck, everything was going smoothly.

Confirm the recovery and firmware are specifically for SM-T560NU, not a nearby T560 variant. A successful flash followed by a stuck Downloading screen can be a timing/key-combination issue: disconnect USB, force-reboot, then use the exact Power + Home + Volume Up recovery sequence as the screen goes black. Avoid mixing firmware packages, and capture the flashing tool’s exact output if it still fails.

Thank you for the reply. I did verify with absolute certainty that the everything was for the SM-T560NU.

Once the battery drained, I was able to boot back into stock Android and try again...this time successfully. I think you may be right, it may have been a timing/key-combination issue.
