Ok, here goes. My apologies if this is complicated.
I didn't want to distribute B&N code or presume what mods where already in your services.jar
adb pull /system/framework/services.jar
apktool d services.jar \Services
Edit \Services\smali\com\android\server\PowerManagerSer vice.smali
replaces 3 lines in the original that have to do with parse / move / setImageURI
Delete those lines and insert the file where the .line statements match.
You can leave both the comments in parta.txt and the .line statements there.
gets inserted at the end of the file.
apktool b \Services services.jar
adb push services.jar /system/framework/
You probably want to clear the cache and reboot at that point.
Note: If you are using the standard slide unlock, the image placement code for that is in android.policy.jar
That defaults to portrait orientation. It is not affected by this mod.
Please tell me if this works for you.
