Well I finally borked it, this D321 no longer has a working lock screen, home button, or app switcher (long press menu key). I couldn't stand not having enough space to install new apps so I started going through various places and deleting various things. I naively decided to try to move /system/priv-apps/LGKeyguard.apk and related .odex to my microsd to save 14 MB; when it broke the lockscreen and home button I moved it back into /system where it goes but it didn't restore the functionality. I definitely did a system->general->storage-->cached data wipe while the apk was absent from the relevant directory. So I intend to try to do a soft reset to try to reinitialize the Keyguard app; I don't know if it will work. First though I'd like to go through my /system/ looking for missing files because I'm not positive I didn't delete anything in /system/ outright before I made the mistake that killed my home button. Also I definitely did some /system/ tweaking when I first got the D321 and that was a long time ago. Can anyone please provide a /system/ file list (with subdirectories) for the stock D321? Or any information relevant to my issue too would be appreciated. Thanks.
