I have a pixel C and the following is happening;
- When I boot normal I can see the google wording in the center of the screen but after that no video is displayed, but I can hear notification sounds like its actually in the OS and I can hear the lock / unlock sounds when pressing the power button.
- When pressing the Power + down buttons I get into an area where I can select fast boot mode or recovery or usb recovery.
- - I can get into fastboot mode and use it but can't wipe data or flash anything because OEM lock is on...
- - If I select recovery, I get the google wording for a while and then I think it just boot loops into the OS again
- - I can get into USB Recovery, but have no idea what this is or how to use it.

Not sure how to proceed or what is up with this no video after the Google wording is displayed. Any suggestions would be helpful.

Here is some fastboot commands output

Code:
./fastboot format userdata

If you are lucky just run fastboot oem unlock or the equivalent fastboot flashing unlock and after that you can flash/format whatever.

Otherwise, if you still have the secure flag set to 'yes' after unlocking, please search a bit: I am personally spamming for days about this issue of brick/bootloop here on XDA.

:D
