Help Last resort for a bricked nexus 7

So about six months ago, my tablet up and died. Won't turn on. Won't charge. No indication that it's literally anything more than a hunk of plastic. Tried every combination of holding down buttons for various lengths of time (up to five minutes) and unplugging/replugging. Got on the phone with google, then asus, who basically told me they need me to send it in and charge me $200 to diagnose and fix it since it was a year and THREE MONTHS old (that got me ticked off-- this thing can't make it a year and three months when I never rooted it, used it in any way that wasn't recommended, and it lived its entire life in a case?). So obviously, **** that. A new one costs less than that.

Anyway, I cracked the sucker open and basically just unplugged and replugged every single cord I could find. Still nothing. So it's not a lose battery cable or something.

Right before it died, I was trying to watch a movie I had downloaded on it. The movie was skipping/freezing and caused some restarts. I tried installing various vlc codecs and programs (nothing needing root) to get it to play correctly, until it finally froze, shut off, and wouldn't turn back on. I have no idea if the skipping/freezing/restarts were caused by the video, or if the tablet was dying anyway which was causing the skipping/restarts, or if the programs I downloaded had anything to do with it (unlikely since it had symptoms before I started downloading anything, but it's a possibility).

Now like I said, it's been six months and I've moved on to another tablet-- a galaxy tab S. And I hate it. Despite being in a case the screen's already cracked from a two-foot drop onto carpet (not exaggerating) and the battery life is terrible. And it doesn't seem to go into sleep mode properly. Blah blah, whatever.

Point being, I'd really like to have my nexus 7 back but since I do have a replacement, I don't want to spend any money getting it working again. if there's anything I can do at this point to save it that doesn't cost money, I'm willing to try it. If I have to pay something, I'll just let it go.

So, any ideas? I'll do anything you guys can suggest, there's really nothing to lose at this point.
 
Check the battery. In many cases, a tablet/phone won't boot up or even respond to a power button if a battery is fried.

Check to see if you have 4-5 solid volts with a multi tester. 3 volts is sometimes not enough to power up device. Keep multi tester on the battery while charging to see if there's even a rise in voltage. Make sure you have a good cable and charging pack.

If no voltage rise occurs, but same charger and cable works on another device, then you have a problem somewhere.

I know Asus 2012 Nexus tablets are very temperamental, but easiest way is to crack'er open and start with the power source itself.

Great thanks. I'll look into it. Do you have any suggestions on what kind of tester for the battery I would need? This doesn't seem like a power issue as I can't imagine the freezing/reboots just before hand would be caused by a fried battery, but it's worth looking in to. It's not a cable issue, I've tried with many different good cables.

In the mean time do you have any other suggestions on what I can try?
 
You could also try removing, let sit and replace battery, see if that works. But there is nothing else you can really do until you are certain battery isn't the culprit.
 
At first I would have said your flash memory died (due to the symptoms described) but even if that happened it should still be able to charge & make it to the Google screen and bootloader.
In some cases when the flash memory just up and dies people give up and leave the tablet to sit till the battery is fully discharged. If this happens sometimes it takes days being on the charger before you can get it to pick up a charge and start taking a charg again.
 
thanks for the thoughts, i'm almost positive i've left it charged for a few days after it bricked, and i'm sure i tried it again plugging it in right after it happened, but after i've left the battery to sit for a while as suggested above, i'll give it another shot.

If it is the flash memory that died, how would I go about fixing that?
 
Yep, I've fixed a couple N7's with dead memory :)
Its all plug & play - just watch a good teardown video on YouTube & pick up a used mobo off ebay for around $16 & you'll be back in business ;)
