I compiled source code referring to http://source.android.com/source/building-running.html and downloaded apt binaries for my Nexus 4g s .I did following after building:
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash userdata userdata.img
fastboot erase userdata
fastboot erase cache
Now, I cannot see anything on my phone. What could be wrong? Wasn't the source I built suitable for my device? But, I am pretty sure I have downloaded correct source code and binaries.
