Install Android M Developer Preview

Now, Let’s get started!

All the files you need to update manually on your Nexus to install Android M are:

Important: ADB Tool package need to be unzipped. After downloading the image package for your Nexus device, extract it to ADB tool package.

Note: Make sure that all the drivers of your Nexus are installed on your computer ( if not do not panic, you’ll know why in step-3). The device must have its bootloader unlocked. Enable USB debugging mode in the device before connecting to your computer.

Now, let us see the steps to install Android M developer preview.

Step 1: Turn your device off with USB debugging enabled.

Step 2: Keep holding Volume Down button while pressing Power button. By this your device will run into Bootloader.

Step 3: After Step 2, connect it to your computer using USB cable. If all the drivers are installed on your computer, it will detect your Nexus immediately else the drivers will be downloaded and installed spontaneously.

Step 4: Goto ADB tool package you extracted before and double click on “flash-all.bat“. This does all your work automatically.

Trouble Shooting

ADB problem:

If you get an error message in the command prompt window with ‘missing the system.img file‘, just unpack the image.zip file in the same ADB tool package. Then, open a command window here by holding Shift and right click, select “Open command window here” and enter the following commands:

>fastboot flash bootloader .img

>fastboot reboot-bootloader

>fastboot flash recovery recovery.img

>fastboot flash boot boot.img

>fastboot flash system system.img

>fastboot flash cache cache.img

>fastboot flash vendor vendor.img

Boot-loop Problem

If something goes wrong internally, you will encounter boot-loop where your Nexus sticks on the loading screen at startup. To get out of this, power-off your device and go back to the bootloader like in above steps and using the volume keys to enter Recovery Mode. In Recovery, wipe cache partition and reboot. If problem persists, again go to Recovery and select wipe data/factory reset to clear everything that is not actually needed.

So, all done properly? Then you made it all the way to Install Android M Developer preview on your Nexus device. This time when you reboot your Nexus device, you should see Android M running.
