Off topic.
Would someone show me which 6000mah battery purchased from Aliexpress would fit this tab? A link would be very helpful. TIA.
The size of the battery is 3.7 x 66 x 125.
It is a tight fit in length.
Take the circuit board off the old battery and solder it onto the new battery (remove circuit board from new battery also and solder short wires onto it, to be then soldered onto old circuit board).

Thanks. Brought two of them.
Then I found a maybe better fit one at Aliexpress/eBay : 3.7v 6000mah 38110114 lithium polymer battery. Basically the size is 3.8 x 110 x 114 mm. Oh well. I have 3 tab all together. May be I will try this one after I perform successful surgery on the first two.

How do you solder the 2 tabs on the old circuit to the new one? I can't, for the life of me, solder tin to tin. Do you use electrical wires instead to connect? I wonder if solder wick would do.

Yes, use the electrical wires to connect. The tin strips (on new battery) do not line up with the solder points on original battery circuit board.

I know..I know... The devs have grown tired of my silly questions, but I ran across THIS link where I found a tool called "create-sdcard" that supposedly would create a nand out of an external sd card and boot the tablet from there instead of the internal storage. The author specifically mentioned this method would help where the tablet would not boot from the internal storage.
So I executed the tool using Oma's update-img and all kind of went well up to the point where it began to unpack the image and failed: "unpacking of Android image unsuccessful...exiting" Has anybody tried this? If not, does anyone have an idea why the update.img cannot be unpacked?
I have this tab that's lying around doing nothing so I might as well try to destroy it and learn something in the process. Thanks in advance for any input.

This doesn't work anyway without bootloader/kernel support.

Is there the same firmware on all three tabs? Can you pls post a screenshot of settings/about the tab?

@buzzly: I am still interested if there are different firmware revisions on your three tabs.

I'd like to test another loader. Pls use this Flashpack: http://crewrktablets.arctablet.com/?wpfb_dl=2956
Copy over the firmware files in folder rockdev/Image and flash incl. LowerFormat.

Oops.

Oma:
Are you asking me to do this or someone else? If it's me, should I flash the uboot file in MaskRom mode first before doing the others? Failing this, is there anyway to restore a backup of stock rom on mine? If possible, can I ask Buzzly to make a backup of your stock rom without any personal info and upload it somewhere? Thanks a lot guys.

Yes. Flash the loader in MaskRom first. LowerFormat and then Run.

Finally some great news. I flashed successfully! It's working fine now. I will recount the process in details later in case people need to replicate it to resuscitate their stuck tablet. Again many thanks to Oma the Man. You beat it!
Edit: Better yet, I'll wait to see if there's any interest from anyone first. The only thing I forgot to test was to flash the TWRP custom recovery, though I have the feeling it wouldn't have gone well since as soon as the RK Tool finished flashing the system.img, the tab automatically rebooted. Also the Tool Oma provided didn't have a slot for recovery. A custom recovery would've been a great help.

Of course there is interest.

Fine. I can repack the build later. Pls try the TWRP first. Rename it to recovery and flash it, just ticking parameter, misc and recovery.
