Custom ROM and "Checking Product...FAILED"

[Oliver Hill]

Hey guys,

I'm putting together a custom ROM for the Nexus 7, and at the moment it is just a clone of AOSP for the Nexus7 (tilapia) with some applications built into the system. As a result, I'm trying to make my own entry into the lunch menu that includes these apps so I don't have to build them individually every time I want to flash a device.

Unfortunately, when I try to flash I am met with:
checking product...
FAILED

Device product is 'tilapia'.
Update requires 'grouper'.

Presumably, the device won't let it flash unless it can identify my ROM as a Tilapia ROM: but as far as I'm aware, I have the requisite BoardConfig and propriety drivers for the Nexus 7, so I'm not sure what I'm missing. If there are any make files you'd like me to post to make things easier to work out, I'd be happy to.

As an aside: I could directly modify the tilapia make files to include my apps, but I'd rather keep things more separate to make it easier to integrate with other devices in the future without having to repeat lots of code.

Now I feel silly, I worked out what the problem was. I needed a board-info.txt file that contains "require board=tilapia".

Whoops.

Beware that grouper is the Wi-Fi-only version, where tilapia also has cellular connectivity. It's possible that builds for one don't work on the other. Worse, it's possible that they'll seem to work but have other issues that'll be hard to spot (e.g. battery issues). I recommend that you make sure that you have the right configuration for your specific device.
