[Galaxy S II Q&A, Help & Troubleshooting] oleost:
Im having the almost the same issue, But I dont have an external SDcard.

I tried "wipe data/factory reset", and flashing different roms, with and without .PIT file.

And sometimes do the phone work 20 minutes before something happens, and sometime it doesnt get past the boot logos. Sometimes in locks up, sometimes i reboot.

I got some adb logcat logs, if someone would be so nice to have a look at it.

This one happend while just browsing the application menu, while switching screen it locked up, nothing happend if I try to press any buttons, except long press power off.
