Koush has released the official builds of ClockWorkMod recovery for the LG Nexus 4 and the Samsung Nexus 10 this afternoon, giving us all a quick and easy way to back everything up and flash bleeding-edge stuff and try to break out new Nexus devices.
You'll find them in the usual places -- the ClockWorkMod site and ROM Manager, but for now Koush is suggesting everyone skip the ROM Manager route and flash by hand.
Because I can't seem to listen to instruction or reason, I had to try the ROM Manager method, and sure enough it doesn't work. If you are as thick-headed as I am and try, you just need to flash the stock recovery back into place and boot into it once to fix your non-booting Nexus 4. Flashing or booting from fastboot works a treat though.
Now we have root and recovery for the N4, let's see how bad we can break stuff!
