Nook Tablet: Doesn't Boot, Hold Charge, Etc. - Barnes & Noble Nook Tablet

Background:
I'll admit, I've been messing around a bit too much with the software/hardware of my Nook Tablet without any real prior knowledge, so this came of little surprise when it eventually stopped working. Originally, I had Rooted my Nook Tablet to expand on its capabilities, but wasn't satisfied; therefore I attempted to run CyanogenMod 10.1 on the Nook Tablet, but I realized (a little too late) that the version of ClockWorkMod I was running was too old to handle Android 4.1/4.2 Jelly Bean, which got the Nook stuck in a bootloop. Additionally, in the process I'd messed up the partition tables and they are no longer intact at all. I then proceeded here, to the XDA Forums, to find a potential solution, and found one that pretty much worked all the way up until I was physically restoring the partitions; I had ADB into the Nook and used a few partition images. After restoring the most important ones I went around to fix the others lesser ones, but the terminal on Linux said I'd run out of space.
After that the Nook had been shutdown with out fully restoring the partitions (probably leaving them corrupt, for all I know) and this is the end result:
1.) Nook cannot boot to any sort of recovery or operating system.
2.) Nook will not recognize and boot to an SD card upon start-up.
3.) Nook doesn't hold charge even though battery is tested and working.
4.) When Nook boots up, there is a large "N" logo and nothing else happens.
So the boot sequence is like this:
1.) Press power button; gives battery low/charge for 15 minutes error.
1.) Plug-in and charge for 15 minutes.
2.) Nook powers on and boots to "N" logo.
3.) Cannot do anything before/after.
Is there any way I can remedy this? Preferably I would like to restore the Nook Tablet to full working condition and restore the operating system to a stock ROM.
Note: I have a Nook Tablet 16 GB.

Go to the Nook Tablet development section. There are tons of guides to unbricking your tab.
The Ubuntu total wipe and reflash method
Unbrick Nook Tablet on Windows Vista/7
I'm pretty sure there are many other methods, but those 2 are the best ones I found so far (with a lot of "thanks" feedback from users).
About the battery level: use any regular microusb charger for a cellphone. Let it charge overnight, then proceed to unbricking.

I should've added the "Bro, Do You Even Read?" to this response too; I should allude to you the fact that I have tried several methods from the XDA Forums (as I mentioned previously), including the total wipe method on Ubuntu as well as Windows (my Macs are undergoing hardware/software upgrades right now, and they're probably too old to be any use for me anyway). Additionally, while the results/symptoms are similar to other cases I hear here and other places on the web, there seems to be some uniqieness about it, which leads me to believe that the device is more than "just bricked".
Tell you what, when I attempted to restore the partition tables initially, it got messed up leading to the device's demise. The internal EMMC as well as any sort of recovery and bootloader has been completely obliterated from existance. The device can no longer physically recognize the micro SD Card Slot, and half the time it won't even boot on command (I have to wait until it feels like doing so when charging).
Secondly, I have tried other USB cables and adapters and I've gotten the same results, I even left it at a B&N store to charge during a one week period and the same results occur; doesn't keep the charge. The battery was swapped with another device and was proven to be working as it charged in the other device just fine.

I think I should also mention that the Windows-restore Method that you linked me to mentioned the following:
"Update: If you have followed every steps from above instruction and still getting "please contact nook support" then you have "erased" factory partition table which means that now your device doesn't have any "build history" associated with it, like serial number, build info and so on. That means that factory ROM will not be able to run without getting that information from your device so your best choice is to call BN or go to BN and get a warranty or replacement service."
And as I said in the initial post, the partition tables are no longer intact, in fact, they no longer exist at all. And when I did bring it to Barnes & Noble, they were of no help whatsoever in my two local stores, so . . .

I guess you're SOL then...
(I always make sure to create a backup of the /rom partition before doing any major mods. That's where the serial number and wi-fi mac address are stored).
Try and see if this works http://raywaldo.com/2012/06/how-to-un-brick-a-nook-tablet-8gb-or-16gb/
