In debug mode after the last exit command that cause GUI to start
press [ALT]+[F1]
plug an USB flash disk, that will appear usually as /storage/usb1
and use following commands:
cd /storage/usb1
dmesg > dmesg_app_that_crashed_YYYY-MM-DD.txt
cp /data/log.txt logcat_app_that_crashed_YYYY-MM-DD.txt

有点意思，反正我会了

BayTrail-Atom_SOC，4.1.13-kernel-by-JJMeijer，启动不了
向rbg大神反馈dmesg和logcat

debug mode下，根目录是@android:/，不同于@android:/android
cd到这个目录@android:/mnt，
make_ext4fs -s -l 1200M system.img /android/system
tar cvf data.tar /android/data
