Last week, I received an update on my Nexus 5 for Lollipop 5.0.1. Version 5.0 was working fine, so I decided to just update. However, a few hours after updating, my phone started to lag and freeze, so I decided to restart. My phone is now stuck in a boot loop and I can't fix it. I don't know what to do. I cant get pass the start up animation no matter what I do.

I've tried the fast boot commands and keep getting the error

FAILED < remote: flash write failure >

I've tried the flash-all.bat file, but the lock state goes back to LOCKED when it reboots the device and I get the error

not supported on lock device

I can unlock the device when I type fastboot oem unlock, but if the device is restarted it goes back to LOCKED.

I've tried recovery mode and I see the below statements:

E:failed to mount /cache (Invalid argument)
E:Can't mount /ache/recovery/log
E:Can't open /ache/recovery/log
E:failed to mount /cache (Invalid argument)
E:Can't mount /ache/recovery/last_log
E:Can't open /ache/recovery/last_log
E:failed to mount /cache (Invalid argument)
E:Can't mount /ache/recovery/last_install
E:Can't open /ache/recovery/last_install
E:failed to mount /cache (Invalid argument)

I've tried wipe data/factory reset

--Wiping data...

E:Can't mount /ache/recovery/last_install
E:Can't open /ache/recovery/last_install
E:failed to mount /cache (Invalid argument)

and still nothing

I've tried the adb sideload and haven't gotten anywhere, it's not recognizing the phone in recovery mode.

I've even tried fastboot erase userdata but nothing happened.

Can anyone help?
