How to do reset/wipe on galaxy nexus with encrypted data My galaxy nexus, rooted, open bootloader, was running cyanogen mod 10.2 with encrypted data.  I tried to wipe and sideload 11 maguro onto it, and install hung on fixing fs_size in crypto footer.

On rebooting it hung on the cyanogen face.  I wiped a few more things and tried to put 10.2 back on and now the encryption password does not work anymore. So I cant boot the device. 

I saw that a total wipe and restart is possible, but Im not sure how.  Sideloading another ROM I am guessing wont help anyway since I cant boot past the encrytion screen as my password is not being accepted.

When I boot into recovery I use clockworkMod Recovery v6.0.4.7

What is the best method to start again with my device, to get some type of OS working on it?  

My options from my recovery menu
- reboot
-install zip
- wipe data/factory reset  (next menu only asks to wipe data)
- wipe cache partition
- backup and reestore (all involving the /sdcard which it cant mount)
-mounts and storage (the next menu does allow for format /system &amp; /factory - but not sure what that will do?)
- advanced (reboots and logs)
If you can, boot into fastboot by holding down both volume keys and pressing the power key, then start recovery and do a factory reset.
