*n00b alert*

Apologies if this is a repost, but I can't quite find the answer I'm looking for, so here's my issue.

- Nexus 7 2013 (Mobile) - 4.4.2
- Mac OS X Mavericks development laptop
- Followed instructions at source.android.com for downloading from master and building the OS
- From lunch, used aosp_deb-userdebug
- make / unlock / fastboot -w -p deb flashall
- Boom! Soft brick! Can't get past the Google splash screen.

I was able to use fastboot to reinstall the factory image -- razorg/KOT49H -- which relieved me greatly.
But I can't figure out what I might have done wrong. It seems pretty straightforward; but I know very little about kernels/recovery/etc.
I am normally just an app developer.

Currently, I am downloading the specific tag for 4.4.2 and going to try to build again, but I thought I'd poll the forum.

Thanks for any suggestions!

Hi, just guessing...you forgot about vendor specific files...?

Thanks for replying!

I noticed that the razorg stock ROM came with a radio img.
I did try to load my system img with the razorg bootloader and radio img, with no success.

if this is a Nexus 7, would I have vendor specific files? I thought the beauty of the Nexus was that you could
pull the source and it would just work :-\

ROM won't work without the proprietary binaries.

You need to download the correct files and then use them to extract the drivers from your device.

Thanks for the help! That was definitely it. Flashing worked fine after that.
I thought I read all the steps correctly...such a n00b.
