[Nexus 4 General] efrant:
I've decided to try and compile a list of the available radios for the Nexus 4 so that people have a "one-stop" for all of them.

Unless stated otherwise, I've pulled all of these myself from either the factory images from Google's site, and packaged them up to be flashable in recovery.

Notes:

1) I have no idea what the differences are between the versions.

2) LTE is disabled in all radios newer than 0.33. If you want to use LTE, you need to use 0.33, 0.27 or a hybrid.

3) For those on T-Mobile who want to use LTE, see this post. Also see this for a recovery-flashable fix for no audio when using older radios on 4.2.2.

4) For advanced users: the radios from the Optimus G do also work to a certain extent, but they require kernel patches. See here.

5) For those that can't tether when using LTE, here are the proper IP tables.

Standard disclaimer: I take no responsibility if you mess up your device by flashing any of these radios.

These are flashable in a custom recovery. To flash using fastboot, extract the image from within, and flash that using: fastboot flash radio modem.img

Downloads are available at this link: Mako Modem Collection. Thanks to bombadier for providing the hosting.

Note: I have removed all the dev-host links that we were previously using. While in the past, dev-host was an acceptable hosting site, in recent months it has gone downhill -- to the point of having misleading multiple "fake" download buttons and sometimes even offering up malware.

I strongly suggest that no one use dev-host as a hosting site for any files going forward.

Unofficial hybrid radios

morrislee has done some great work: he replaced the core modem components in 0.84 with those from 0.33 and 0.27. See his posts here and here. This enables us to use LTE and yet have all the newer features (power management, audio on T-Mobile, etc.) from the newer radios.

See this thread for discussion/information on hybrid radios.
