I would recommend against pulling eMMC off the board unless there is no other way, because the connector used for eMMC modules is not rated for many mating cycles and I would expect it to wear out fast.

Okay. I'm sure I have the eMMC switch turned OFF (flipped it from the hinges, to the down position) and now when I try to boot it, I atleast get a green light, and that's it

A serial console would tell you what's happening. Else try a different OS, different SD card.
:wq

Serial console? Haha. Remember, I'm a noob. But, I do believe I'm getting somewhere, I think, I hope. During my millions of different threads and searches I remember seeing a post somewhere and vaguely remember it saying something about quickly switching the eMMC switch when booting up (or something to the sort)

It then starts up with a whole different string of texts, but the result is: direct firmware load for failed with error 2 (or something. Sorry, but I'm at work so I can't send screen shots)
BUT THEN! I'm somehow able to access the Emergency Mode, but really can't do much since I don't know the root password

Ignore the error 2. I think this about usb C video
What had you booted,, is it the Sd card? OR emmc?
i imagine that you are in a terminal, so
id
whoami
uname -a
mount |grep dev
lsblk
If you have sufficient permissions, edit (on emmc) /etc/shadow, make root passwordless
As I said before, search forum, all explained previously
(search .... passwordless OR shadow)

Just got off work, and I am about to take another crack at it. I just wanted to say thanks again for you're help. I'll let you know the results

As for what I booted, I BLEIEVE the SD Card, but I'll let you know

Okay. I found one thread and was reading, but then I kind of got confused. At first it says:

Quote:Then it depends. If you're on a computer that can run Balena Etcher, just select..
 But then a little further down it says:
Quote:We can't use Etcher on the Pinebook family, so we need to do it manually. It's not that hard as long as you're really careful

Sooo, can we or can we not use it?.

Balena Etcher ????? how can you use etcher on a non-working computer??
I am not sure, I don't think there is an arm version of etcher
Most people, after a little experience, use dd,, just be carefull
something like
xzcat someImage.xz |dd of=/dev/sd bs=1M status=progress
(replace /dev/sd with right /dev/mmcblkX,,, X= 1 OR 2)
uname -a will tell you what is booted,, id OR whoami will tell your permissions
Must be root to edit etc/shadow, to fix your forgotten password
