When I woke up this morning, my N6 suddenly couldn’t start. I was very confused and tried all kinds of methods to no avail
The final decision is to brush the machine
Since you’ve been manually root before, let’s briefly describe the process.
Reference: http://www.muzisoft.com/shuaji/85161.html
First: You need tools
First need to enter Fastboot mode: http://jiyouhui.it168.com/thread-435764-1-1.html

Nexus6 can use Fastboot tool: http://jiyouhui.it168.com/thread-435762-1-1.html

this tutorial applicable models:

– the Nexus 6

a: Use the Fastboot command to write the mirror parts of the system:
The corresponding partition to be painted & GT; < The image to be painted in a directory & GT;

tip:

brush mirror, due to the use of the CMD command, the computer is not intelligent, you must put the mirror in the fastboot tool root directory to be able to brush… It’s a hassle. What can I do?!

Remember the fastboot space flash space system space, do not mistake, the space must be entered, do not enter the space will report an error!
If the driver doesn’t connect: Download the MOTO driver

When the driver connection enters the fastboot mode normally, it will be found that when the machine is swiped,
Error: update package missing system.img reports this error
This is because there is a problem with loading img images when swiping. Google compressed most img images into a zip compression package, the file name is image-hammerhead-lrx21o. Zip

.

brush command as follows:
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash cache cache.img
fastboot flash userdata userdata.img
fastboot reboot

So I simply modified the code for fastboot-all.bat
