[Q] Stuck at "erasing userdata..." topic

Hello,

Recently my Nexus 7 (2013) battery ran out because I forgot to charge it. Since then, it won't boot back into Android when it's turned on - all I get is the black screen with "Google" written on it. I have searched all over the internet for the past few days, but I'm unable to find a solution. I'm hoping that someone here can help me, because the tablet's warranty has expired and I'm completely out of ideas. Here are the things I've tried or noticed:

• I can't boot into Android. The tablet gets stuck on the black screen with "Google" written on it.


• I can access the bootloader and interact with the tablet via fastboot.


• The bootloader is locked. Trying to unlock it via fastboot oem unlock displays the "Unlock bootloader?" screen on the tablet. After I select "Yes", the command line output on the computer shows the following output, but doesn't get any further:
  
  
  

  Code:

  
  

  ---

  ...
(bootloader) Unlocking bootloader...
(bootloader) erasing userdata...

  ---

  
  


• Trying to boot into recovery mode from the bootloader results in the tablet being stuck on that black screen with "Google" written on it.


• I have removed the back cover from the tablet and reconnected every exposed connector. I couldn't take the battery out because I don't have the appropriate screwdriver. Doing this changed nothing.

Any help would be sincerely appreciated. At this point I'm worried that it is a hardware issue, but I'd like to exhaust all options before declaring it as such, as it would essentially mean the tablet is going in the garbage bin.
