Flashing stock image without unlocked bootloader

Can I flash stock image from Google's site without unlocking bootloader? My phone is defected and came without a recovery image in the software meaning I cannot update to 4.0.4 or perform factory wipes, so does this mean i cannot unlock bootloader? I need to unlock bootloader to flash stock 4.0.4 image correct?
The recovery and bootloader are seperate things. If you can boot into the bootloader you can unlock it. Hold down both volume up and down and power. It should boot you into the bootloader.
Yeah i'm pretty new to this so thanks for the response. I can get into fastboot mode by holding the power and volume buttons down but entering recovery mode does not work. I know that during the unlocking the bootloader process it causes a factory wipe, but theres no recovery image on my phone for my phone to revert back to, so what would happen?
You dont need to go into recovery to unlock your bootloader. You do it from fastboot itself. After unlocking you can flash the system image which includes the recovery.
Follow this tutorial: http://forum.xda-developers.com/showpost.php?p=25477039&postcount=1 It will walk you through the whole process.
Thanks a lot. Im in the middle of unlocking the bootloader now and that link will really help me flash the stock image. thanks!
No problem. If you get stuck either PM me or post to this thread again.

Locked bootloader flashing possibilities

I'm seeing comments all over the web that you don't need to unlock your bootloader to flash a recovery. Is that true and can anyone confirm this. I'd like to just flash a recovery on my device and make a stock backup all without unlocking the bootloader.

relocking the bootloader ?

is it possible ?
yep
Code:
fastboot oem lock
Thanks upvoted
but last small question relocking my bootloader will restore my warranty ?
Depends if service can read flash counter
As far as I can tell, you should be ok as long as you flash stock firmware and relock
Ok thanks

Relock Bootloader Possible?

I have pixel 3a xl with bootloader unlocked, no root and stock kernel, its possible relock bootloader?
I always suggest flashing the Google factory image (not the OTA images), including the full factory reset before relocking the bootloader.
But yes, if you are 1000% sure your entire system is stock, then you can relock the bootloader.
I wouldn't do it... If anything ever gets truly fubared you will be glad it's unlocked.
If you lock it you lock out a few additional possibilities to recover your phone.
