    When I’m doing the “fastboot flash system system.img” command it says “load_file: could not allocate 1778070480 bytes
    error: cannot load ‘system.img’

    Any idea what might be wrong? I’m on a Nexus 6, rooted and bootloader unlocked

      The same here i don’t no why. I’m trying to figure it out

      • Jaimy says:

        I may have found the solution. Using the Nexus Root Toolkit, I went into Advanced Utilities and selected the System option under Fastboot Flash. My phone is rebooting right now and optimizing all the apps.
        I’ll let you know how it all went

      • Jaimy says:

        Works! Do what I said in my previous comment and you’ll be on 5.1 in no time

Stuck on the installation file UPDATE-SuperSU-v2.37 (I was on stock firmware and have no custom recovery so i couldn’t install this file).
