Then just wait a long time for the flash to happen, the device to reboot, and for your new version of Android to boot. Then you just need to run "flash-all.sh" from the terminal. Then hit "control+X" on the keyboard, "y" and then "enter" to save, and you're done. That means opening up a terminal, typing "sudo nano /etc/paths," entering your password, and adding the path of the "Platform Tools" directory to the bottom of the file. On Mac OS, you'll need to add the "Platform Tools" directory to your $PATH variable.
Double clicking on "Flash-all.bat" should take care of it. Now you just need to run the "flash all" file. Flash the image fileįor the next step, you need to be in Fastboot mode again, so if the phone booted into the welcome screen, turn it off and turn it on while holding the "volume down" button to get back into fastboot. Pick "yes" and the phone will unlock and wipe itself. To navigate on this screen, the volume buttons are up and down, and "power" will select your choice. Saying "yes" to this will be the first of two data wipes that will happen, so make sure you're ready for all your data to be deleted. If your phone says "LOCK STATE - locked" on the Fastboot screen while your phone is still in Fastboot mode, you'll need to run "fastboot oem unlock." This will pop up the next screen in the gallery, above.
Fire up a terminal/command prompt and navigate to the Platform Tools directory. At the bottom of the Fastboot screen, there should be a line that says "LOCK STATE," which will say either "locked" or "unlocked." We want it to say "unlocked" so that we can flash what we want to the device.Įither way, while on the fastboot screen, it's time to plug the device into your computer and run some commands. This isn't referring to carrier unlock, but rather unlocking your bootloader so you can flash a new version of Android. Next you'll need to "unlock" your device. Make sure you aren't just copying a single folder into "Platform Tools." The key here is that the "flash all" files end up in the same folder as the file called "fastboot." From here, grab the factory image you downloaded, unzip it, and place the contents in the "Platform Tools" directory of the SDK.
