I can't give you a definite answer, but maybe offer two hints: I used abootimg & fastboot boot in a similar way in the past on some Android device and I think I did something with the kernel commandline. Something like firstly getting the old commandline and more info out of the old .img with abootimg -i and then creating a new .img via -c ? Alternatively maybe you can get something meaninigful from cat /proc/last_kmsg after a subsequent reboot: http://stackoverflow.com/questions/9682306/android-how-to-get-kernel-logs-after-kernel-panic Good luck! -- Mailing list: https://launchpad.net/~ubuntu-phone Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-phone More help : https://help.launchpad.net/ListHelp
