I gathered boot logs and other information of various Android devices.

How to get log

Connect the target device by USB cable, Power off and on the device and wait for boot up, then type the following commands.

$ adb shell dmesg > dmesg.txt
$ adb shell logcat -d > logcat.txt
$ adb shell cat /proc/cpuinfo > cpuinfo.txt
$ adb shell getprop > prop.txt

If there is kernel config, save it.

$ adb pull /proc/config.gz
