    My Nexus 5 just failed yesterday. In recovery mode I get this message:
    Code (Text):
    1. Supported API: 3
    2. E: Failed to mount /cache (Invalid argument)
    I followed this tutorial step by step by whenever I try to "flashboot flash" something (cache, system, etc.) I get this error message:
    Code (Text):
    1. FAILED (remote: flash write failure)
    I can confirm the bootloader is unlocked:
    Code (Text):
    1. fastboot oem unlock
    2. >> unlocked: yes
    3. >> finished. total time: -0.000s
    More details:

    Following this thread I suspected a problem of size so tried to increase max size:
    Code (Text):
    1. fastboot -S 2048M flash system system.img
    2. erasing 'system'...
    3. OKAY [  0.126s]
    4. sending 'system' (1020657 KB)...
    5. OKAY [ 32.239s]
    6. writing 'system'...
    7. FAILED (remote: flash write failure)
    8. finished. total time: 32.537s
    Code (Text):
    1. fastboot -S 2048M flash cache cache.img
    2. erasing 'cache'...
    3. FAILED (remote: failed to erase partition)
    4. finished. total time: 0.217s
    Code (Text):
    1. fastboot -S 2048M flash recovery recovery.img
    2. sending 'recovery' (10014 KB)...
    3. OKAY [  0.521s]
    4. writing 'recovery'...
    5. FAILED (remote: flash write failure)
    6. finished. total time: 0.708s
    I am now clueless... This is a 5 year-old phone so it could possibly be a hardware failure but I really really want to make sure I tried everything I could to save the guy!! (even though data is long dead by now).
    Any thoughts?
