[Q] How to factory reset with broken screen

---

I'd like to wipe the data from my Galaxy Nexus to send it for repair, but since the screen is blank/broken, I have no feedback to my adb commands, and no way to press on screen prompts. The device is stock, unrooted. Doing adb shell/wipe data gives me no permission, so I think I need to be in bootloader or recovery.

Does any guru here have the steps required to wipe data/factory reset in such a screenless/touchless mode?

you could root it then wipe it using adb like you said.

Just in case someone needs this here goes:

You do NOT need to be rooted. Just install ADB and fastboot.

Turn on your device in bootloader mode, hold volume up and volume down and power button simultaniously, until you feel a vibration, then let go the buttons.

Connect USB cable to PC.

Run ADB as root, type: adb root

Check you are in in fastboot mode and connected, type: fastboot-linux devices

This should show a long number

Finally, type: fastboot-linux -w

And just to be sure type: fastboot-linux erase data.img

fastboot-linux reboot

Or you could fastboot flash the stock images that are provided by google. Fastest method, even more since zyo made a one-click batch file for that.

If you want to make sure everything is wiped correctly, you could boot the phone and connect it with a screen via MHL.

ok. so putting the device in bootloader mode is easy. but trying to understand what you mean with "run adb as root" ??

this what i did, i run cmd and see C:\user\name>

typing C:\user\name>c:\adb (which is where my adb folder is located)
only gives me this message:

'c:\adb' is not a recognized as an internal or external command, operable program or batch file.

can some1 give a step to step guide or give a me link that tells me how to do this?

Type: cd c:\android-sdk\platform-tools to be able to get in the tools.
c:\android-sdk is the location where i have my sdk tools, if yours is different type that instead. Place the sdk directly on the c drive, not in a (sub) folder.
Than type: adb reboot-bootloader and you`re in fastboot mode.

I f you`re not familiar with adb/fastboot i advice you to do this:
Install GNex Toolkit from here http://forum.xda-developers.com/show....php?t=1614827, Flash a google image from here https://developers.google.com/androi...es#yakjuimm76i.
Install the toolkit, do option 1 (drivers), put the downloaded and the not to be extracted google image (.tgz file) here C:\Galaxy Nexus ToolKit\put_google_factory_image_here ,put your phone in fastboot mode and do option 8. After that lock the bootloader.

ok, i tried the Gnex toolkit and i believe it worked. i can see the serial ID when its in fastboot mode. and i followed all those steps to restore the img.
yesterday i just bought an original samsung mhl adapter. i tried to connect it with my Gnex, plugged in the power cable and tried to connect the hdmi cable both to my pc monitor and my flatscreen tv. nothing works. i tried connecting all the cable first while the phone was off and then turn on the Gnex. still nothing works. no Signal/no Device is being recognized by either monitor.

Is there a way to get this to work, so i can see my Gnex "screen" on any Monitor?
