[Q] Nexus 5 factory reset fail - red triangle / erasing topic

Hey there, I have an interesting problem with my nexus 5.

Since the update to 5.0 (sideload) the phone was laggy and not responding well.
I waited for the 5.0.1 OTA, hoping that it would solve the problem. It got better, but the performance still didn't feel right.

I decided to do a factory reset today, which seems to have failed somehow...

I chose the option through the settings menu, the phone powered off and the erase android came up.
The erase was on for approx 10 minutes, then the red triangle android came up. While I was checking for solutions on google, the phone went back to erase and is stuck there now since approx 30 minutes - not sure if I missed a repetition of the above in between.

I couldn't find anything matching in the search - please let me know if anyone has seen it before and/or knows a solution.


Thank you!!

[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.
