After editing it and rebooting it got stuck on a LG boot animation. I can't get a logcat during boot but thankfully I have full rooted ADB access in stock recovery mode, Could any fellow L7 II owner give me his unmodified "media_profiles.xml" so I can replace it although I have a bad feeling that it's not causing the problem because I (think) I reverted all the changes in it before pushing it back with ADB. So someone with L7 II post their media profiles file or tell me how to get adb while booting so I can diagnose this problem myself.
Reflashing kdz's is a LAST resort.
This is the screenshot of some of the files in /system/etc and underlined one is the presumably correct media_profiles.xml that I pushed back using adb in hopes of fixing the bootloop.
Could the different date be the problem?
