[Q] Flashing Samsung Logo no boot I9100
I have a curios problem with my Smasung Galaxy S2 9100 ( German Model without Branding and 4.1.2 Stock ROM!) 2 days ago I had to charge the battery... As this was finished I plugged the cable off and switched the phone off. Next morning I tried to start the phone but it hangs up on boot. The flashing Samsung Logo stay on screen and the phone becomes hot.
So after 2 days of playing around with factory reset, adb shell and clockworkmod ( Installed after the crash (jeboo_kernel_i9100_v1-2a) ) I find out that the problem must be a App or similar. When I wipe the /data Folder with CWM Menu the Phone start up normal and comes with the Welcome Assistent. But then all my personal data is lost -> Not good
( I have made a nandroid backup with cwm so I can restore the defective state again and again)
So now my question : How can I find out what is the root cause ? I need a bootlog or dmesg logfile to find which component hang up the system on boot. I want to find out why it happend and how I can prevent it next time.
How can I debug this issue ?
Thanks and Greetings for your help.
