Stuck at Google Screen won't do anything HELP

[Cr8zyJay]

Yep tried all of the above and nothing. It will not boot up after the toolkits or sdk cmd prompt forces the reboot. Also when I try to unlock my boot loader I receive a

 FAILED <remote: <Unknown error code>>

That unknown error is what the problem is and that is where it would tell me the bootloader is locked when I was trying to flash original onto it. Like I said I'm new to Android but pretty fast at learning. I know that I have tried everything I could find online on both the Win8 and Win7 PC. I'm wondering if it's a hardware issue. Still would love to get to the bottom of it. It will reboot ONLY in fastboot mode. Nothing else. Not recovery nothing...

Well since you got the android boot loader interface driver and it makes it past the bootload stage to the Google logo, I would think that the boot loader is not corrupt, which is about the only hard brick I've heard of. So try multiple cables and ports and possibly a linux partition. Did fastboot devices return an alphanumeric string followed by fastboot?

Don't use front ports or USB 3.0

I'm not sure what you mean by front port and the usb are all 2.0

Also it says the following when I do the soft bricked restore from Wug rootkit
sending 'bootloader' <2100kb>
FAILED <remote: Bootloader is locked.>
finished. total time:0.145s
rebooting into bootloader...
OKAY [ 0.020s]

But the OEM unlock says failed to unknown error

It does say a bunch of stuff about clearing cache and things like that but none of this is on the tablet it's on my PC. So it's possible it's the cable I got? What specs of a usb cable should I look for?

Front ports usually aren't directly connected to the motherboard..

If your bootloader is unlocked, you'll see an unlocked padlock icon below the word "Google" as your N7 boots.

The front ports on a tower PC have long internal cables of dubious quality to the motherboard header. Rear ports next to the lan and KB etc are part of the MB and should work better. A good quality cord should look be a little thicker because of larger gauge wire. I've got a number of cheap cables that don't work well. The original cable usually works, if you've got it. USB 2.0 type A to usb micro.
There are options in recovery to wipe the cache and dalvik cache on the tablet, but if you can't access recovery with the button presses already mentioned, there may be a corrupted nand chip. Birdastrompgman has a thread on here where he replaced his main board. If you can't get fastboot to flash an image, reformatting the nand memory in the process.

Open a command prompt in the folder with fastboot, type    "fastboot devices".   Enter.
what message appears? This is the easiest way to check that everything is communicating.

I'm not sure you're running fastboot correctly. Does "fastboot devices" return the device serial number? Does "fastboot ?" return a list of options? Are you running fastboot  from the correct sdk/... /program - tools directory?

I just saw your post on XDA Developers. You didn't tell us it doesn't do anything after you unlock the bootloader. That indicates a corrupted bootloader. Check that by installing the universal naked APX drivers to your PC and see if it's recognized as an APX device.

If you can install another bootloader with fastboot, you can save your device.

Ok, and as for the Google screen I don't even have a picture of a lock it's just the word Google. The only way I know that the bootloader is locked is from reading it on the fastboot screen

Awesome. I will be working on this later today and give you an update! Thank you both very much for your help in all this!!!

Yes to all of the above

So I downloaded and installed the new drivers as I can see them on my USB drivers list (APX) but my laptop still will only recognize the tablet as a Android Device-Google Nexus Bootloader.

Also when I go to unlock it I keep getting that unknown error message as to why it's failed. So even though the bootloader says it's unlocking the SDK on my Laptop says it failed. At that point the tablet freezes. Either in the bootloader screen stating it is unlocking or if using a root toolkit at the rebooting of the tablet it never turns back on.
