Anyhow, it looks like they want "those who dare" to give it a try (which hopefully will be a better testing grounds for them than their own engineers).
So, if you've got a Nexus 7 (2013) or a Nexus 5 go and give it a shot... if you dare!
It's much like using the factory images we've posted about how to use for previous updates.
Go grab the image files here: http://developer.android.com/preview/setup-sdk.html
Do as you normally would as we've outlined in other instructions:
- extract the .tgz
- then extract the .rar
- run the 'flash-all.bat' file...
- (Normally I suggest modifying the line with the fastboot -w udpate..., but with this there might be some specific issues... so best to start all fresh)
Should be good to go after that. (if you have trouble, hit me up on Helpouts)
So, are you going to give it a shot? I'm going to wait until there's a preview for the Nexus 4 (but I doubt it). ROMs might start appearing for various devices, but I'll wait before I monkey with my current daily driver. Might experiment on the N4 tho'...
