Can't delete a rom (CM11) to install new one
****edit: It appears that the option "format /system" which is tucked away in a sub menu did the trick and erased the rom.
I am trying to completely delete a rom I have installed which is CyanogenMod 11 but it seems to stay no matter what, or I'm not doing it right.
First I go into recovery with the power+vol down and choosing recovery.
I have ClockworkMod 220.127.116.11.
From there I choose the wipe data/factory reset and also the wipe cache partition and wipe dalvik cache.
Then I choose the install zip from sd card to install Blackout_ICS_Incredible_v4.0.zip
After following the installer instructions and rebooting it goes back to CM11...
Any ideas how to wipe CM11 from my device?
