I had posted a brief thread a couple weeks ago stating that my Nexus 4 restarted by itself, and got stuck in the bootloader animation loop. I couldn't remember whether I had enabled USB debugging in my phone prior to it killing itself (not rooted, completely stock, did the OTA 4.4.3 update just a few days before my phone died, and phone's been out of warranty for quite a while now ).
So I installed the SDK developer tooklit, and followed instructions to set up ADB.
However, everytime I boot my nexus 4 into recovery mode/"safe" mode, I get the following screen ("Screenshot 1" below).
From there, when I boot into recovery mode, I get the following screen ("Screenshot 2").
Every time I connected my phone to my laptop (keep in mind that I cannot start it .. I always plug it in when I'm in "Screenshot 1" mode) and try to used "adb devices", I get the following cmd screen ("CMD ADB Devices" picture below). I've repeated this process and tried plugging the nexus in during various points in different "safe mode" options. Same result: nothing is detected.
So I got frustrated at trying to backup any data from my phone, and just chose the "wipe data/factory reset" option from the nexus recovery mode, and I got this screen ("Screenshot 3"). I've tried this several times, and I keep getting this screen.
So my nexus committed suicide, and I'm totally not sure what to do. I've been trying to learn how to use ADB etc for the past couple of days by scouring through the xda nexus 4 forums, but I'm still very much a n00b. Do you guys have any advice as to what I can do to get my nexus 4 back to a usable state again?
Things I've already tried (in order):
I also tried to ADB sideload a stock Nexus 4.4.3 factory image, but it is useless since my device won't even show up in CMD when i enter ADB devices.
However, the problem is that my nexus is never detected in CMD no matter what combination of things I tried, so I can't even do half of the things both of those thread instructions state.
I would greatly appreciate ANY ways to factory reset or flash working firmware on my phone!
Edit: I reinstalled Android SDK, and connected my nexus to my laptop after entering fastboot ("safe" mode; volume down + power from phone off state), and I was able to get a slightly better looking CMD window when running ADB Devices command (See "CMD ADB Devices 2" picture). However, same problem as before, where my phone isn't even registering via ADB.
So again, your input would be tremendously appreciated.
