This file contains various things we've found out while getting B2G working on various devices.
Samsung Galaxy S2
Device Enters Reboot Loop on Factory Reset of Stock Firmware
If you run a factory reset on the stock firmware, the restored /data/system directory receives the wrong permissions. This will cause the device to enter a boot loop. To fix this, adb shell into the phone (the boot loop doesn't effect adb), and change the /data/system directory permissions to 700. This should cause the phone to continue boot through to the GUI.
Samsung Galaxy S2 (GT-I9100G) Model is Unsupported
The Samsung Galaxy S2 (GT-I9100G) uses different chip from generic SGS2 GT-I9100 phones. Hence B2G doesn't support this model yet.
