About "was flashing ROMs before":

There's the trap. Each device requires a different strategy to prepare it for flashing a custom ROM; it's not as straightforward across devices - even within the same vendor - as you may think. The other trap, which isn't obviously clear from "just reading through the <insert name of ROM here> OP post" is that the more recent ROMs require an updated recovery for successful flashing.

To wrap it up:

CWM 6.0.2.7 is to be used with CyanogenMod 10.1.2 ONLY

CWM Swipe Edition, Philz Touch Advanced CWM Recovery and TWRP are to be used with CyanogenMod 11 or OMNI

TWRP is to be used with OMNI (with the official Nightlies it's even required so you can flash the nightly delta updates, to my knowledge CWM does not support the "OpenRecovery" scripting).

CWM Swipe Edition, PhilZ Touch and TWRP are all provided by AndroidAndi through his file repository on AndroidFileHost.

As for "destroyed battery":

No, I don't think you "destroyed" the battery. That's not easily doable. However, if the battery is deeply depleted the charging circuit may not want to start charging because it has to pull a whole lot of current (current = Amps). Normally a properly designed charging curcuit shut down in case it goes over-amp to prevent damage.

What I don't fully understand is that you can't get into download mode, though you said the tablet will at least show you the red "Battery Empty" screen for a brief moment.

Anyway, disconnecting and re-connecting the battery doesn't help you in any way. I would try to get some juice into the battery by using a silicon diode (that are the tiny diodes with that copper/brown glass body and the black stripe on one side denotig the cathode) in series with the +5V line coming from the power supply to drop the voltage to ~4.3/4.4V and let it try to charge for... let's say 30 minutes for a start while also keeping an eye at the temperature of the battery (just touch it every one or two minutes, and if it gets too hot to the touch (~ 122°F/50°C) disconnect the power supply and let it cool down if the 30 minutes aren't up already). BUT... Do NOT use any power supply outputting more than 500/750mA for safety reasons! Once you charged for some time connect the battery to the tablet's motherboard and see if it shows a change in charge (i.e. slightly green instead of red). If that works just charge it up a bit more until you're at ~50/60% charge.

Then prepare ODIN + Stock image or ODIN + custom recovery and see if you can get into download mode to flash (avoid having the tablet turned on for too long to save battery - once it's connected to the PC and flashing it draws power from the USB anyway).

If that does not work out no matter what you try, because you managed to screw things up really good, using a JIG to flash through JTAG is then your last resort of recovery (if you can get hold of a readily-assembled one or are able to build one yourself).

As for the confusion about the resistor. I wasn't referring to a JIG. I was talking about putting a resistor (possibly 10 Ohms I would assume) across the positive and negative pins of the pins where the battery connects with the motherboard (and while it's connected). That acts as a "current limiter". In this case the battery can't attempt to pull too much current, therefore avoiding the charging circuit from shutting down.

If you have any questions feel free to ask.
