Trying to install Copperhead OS on Nexus 6P I want to install CopperheadOS on my Nexus 6P. They have installation instructions here: https://copperhead.co/android/docs/install

Unfortunately, I'm already stuck at the beginning. The installation instructions say that I need to extract the factory images and flash them. Unfortunately when I try to flash them, as soon as it reaches the system partition it returns the following error:

sending 'system' (1174469 KB)...
FAILED (remote: data too large)

I am now unable to boot the phone at all, and stuck in the bootloader. What can I do?
wrong fastboot!

1st i used android-tools-adb and android-tools-fastboot from ubuntu -- didn't work - same error

following the instructions https://copperhead.co/android/docs/install - it worked
