After successfully unlocking the bootloader of my new Nexus 4 using adb and fastboot I now want to install ClockworkMod Recovery onto my device. Sadly it is not working properly. I am using Gnome Ubuntu 13.04 and installed adb and fastboot with apt. While in fastboot mode my device is visible when testing with
$ sudo fastboot devices
002847af108bXXXX fastboot
when I try to flash the ClockworkMod image recovery-clockwork-6.0.3.6-mako.img using
$ sudo fastboot flash recovery recovery-clockwork-6.0.3.6-mako.img
sending 'recovery' (7814 KB)...
it gets stuck. I already waited for 40 minutes to complete but since the size of the image is around 8Mb I suppose it cannot take that much time and something is not working correctly. Strangely also my USB-connected keyboard and Bluetooth-connected mouse are ignoring my inputs while fastboot is running.
I also tried renaming the .img file to recovery.img with the same result. Perhaps I am missing something obvious, but I have no idea what the problem could be.
sending 'recovery'
... Any ideas or more recent experiences?
