Google has just rolled out the highly-anticipated Developer Preview release of Android M for only Nexus 5, Nexus 6, Nexus 9 and Nexus Player users.
There is better news for avid Android fans, as Google has also announced that the preview version of Android M will be updated more often than the Android Lollipop as the updates will be rolled out over-the-air.
Warning: This is a preview of the update so all the data will be erased after completion of update and there may be any bug issue and unfinished features since its not the official update ,this is for testing and to do more improvements .
Users can download the update, follow the steps given below:
Step 1. First of all you need to download the correct factory image for your device click on your device name to download Nexus 5 ,Nexus 6 ,Nexus 9 ,Nexus Player .
Step 2. Now you need to enable USB debugging, which will essentially let your device know that you want your computer to interact with it. To do so, you need to go to Settings menu and scroll down to the About placard. Click on this for seven times and you will see a confirmation message stating you’re a developer now. Now go back, and you'll find a Developer option, upon entering, you will find an option to enable USB debugging.
Step 3. Once you’ve downloaded factory image for your device, extract the files (and also all the individual files) into an easily accessible folder and grab drivers and tools that are required for your computer to interact with your device.
Windows users will need to download an ADB driver, to download click on ADB. After completion of downloading launch the app and type only 'y' to start the installation.
Step 4. Assuming that you have fastboot and adb already set up and ready to use, just follow the commands below in order.
adb reboot bootloader
This will restart your phone into the bootloader mode. This will only work if your phone is connected and you have USB debugging turned on.
fastboot oem unlock
If your phone is already OEM Unlocked, you would not have to do this, but it wouldn’t hurt if you are unsure.
bash flash-all.sh
This will run all of the fastboot commands needed for the complete image flash. If you are using Windows, rather than a bash script you will use the flash-all.bat (batch) file. One common issue of this not working is that you do not have fastboot setup properly and is not set as an environment variable (a variable that works system wide).
Step 5. On Windows, you will have to flash the following files manually. Type in the following commands:
fastboot flash boot boot.img
fastboot flash cache cache.img
fastboot flash recovery recovery.img
fastboot flash system system.img
fastboot flash userdata userdata.img
This will flash all of the needed files.Your phone will restart and will take more time than usual to boot for the first time. If you have any problem comment below.
