Nexus 5 stuck in rebooting loop

Something is wrong with my Nexus 5, it is constantly stuck in a neverending loop of restarting even when I don't touch the phone, it is rebooting before it even finishes loading the OS. It has full battery, and I've tried doing a factory reset. The phone reboots before it can even finish initializing the factory reset. This all started randomly when I was walking home from work listening to Audible, it has been 4 days of being unusable. I have not installed any apps recently, and nothing on my phone settings wise has changed. I do not use a custom lock screen, or any other sort of OS mod.

Please help! I do not want to spend $600 on a new phone already.

From the link below, select the second option, (Reset device in Recovery mode) and carefully follow the instructions for resetting your Nexus 5. This method will allow the phone to perform a full factory reset within the Android recovery and should resolve the bootloop problem.

If this fails to yield results and as a last resort, you may need to re-flash the Android operating system onto your Nexus 5. Instructions are provided in the link below.

The first solution did not help at all. I reset to factory settings from Recovery mode, and upon completing and getting back to the OS, it proceeded to resume crashing.

Now I'm a game developer and I cannot for the life of me figure out how to flash this device, especially since it won't stay on for more than 20 seconds at a time before rebooting. I guess it's just screwed and I have to get a new phone.

When in bootloader aka fastboot mode, the phone won't shut off as it does when it tries to load the OS. This mode will allow you to flash firmware to the Nexus 5. There's a different method for putting your phone in to fastboot mode. Nexus 5 code-name: Hammerhead.

Remember to turn the device off, then turn it on and immediately hold down the relevant key combination for your device.

Booting into fastboot mode

There's no point booting your phone into fastboot mode until you have the Android SDK installed. Included in the SDK under the 'platform-tools' directory is 'adb' and 'fastboot', protocols which allow you to execute commands from the command line that can unlock or re-lock the bootloader and install a factory firmware image onto your phone.

When did you get this phone? Do you still have a warranty? If so, you might want send it to warranty repair.

I got it in March 2014 with my Koodo plan, so I'm fairly certain that the warranty is done
