N5 can't boot to either phone or recovery. Stuck at Google splash. topic

Out of nowhere my completely stock Nexus 5 just shut off and wouldn't get past the Google splash screen when I powered it back up. I've tried the following:

• Using fastboot menu to load stock android recovery - BLACK SCREEN AFTER SELECTING THE RECOVERY OPTION


• Using fastboot to send over the factory image and start fresh - HALTS DURING DATA WIPE


• Unlocking the bootloader to install a new recovery - HALTS AT DATA WIPE (i'm supposed to see the wipe progress but i dont get any further than the ellipsis)

I'm no android expert but it appears as though the partition in which the recovery menu and android OS live has fried.

Any advice? Thanks for the help!
