SYMPTOM: When I open Gallery, it immediately closes (it never displays any photos or thumbnails). CAUSE: I added some .nomedia files to my SD card (to hide album art from showing up in Gallery), and that's when Gallery refused to open. It just immediately closes/disappears anytime I try and open Gallery. SOLUTIONS ATTEMPTED: I'm trying to avoid a factory reset if possible. Here's what I have tried so far: Cleared data/cache for Gallery app (at Settings>applications>manage applications>menu button>filter>all>gallery>clear data and clear cache). Problem still persists. I tried to repeat this, and now the Clear Data and Clear Cache buttons are both grayed out even after I force close Gallery. Removed the files under: SD Card\Android\data\com.android.providers.media\albumthumbs Removed SD Card\DCIM\.thumbnails directory Removed all photos from the gallery and see if it still crashes. I manually deleted the DCIM folder, and snapped a couple test photos to force the recreation of the DCIM folder. I can view Camera Roll from the camera app, but Gallery still refuses to open. I have also booted to recovery mode and noticed the following error: "E: Can't open /cache/recovery/command" From recovery, I used the "Wipe cache partition" utility, rebooted, and Gallery still won't open. What else can I try? I'm at a loss here. I see a file called "thumbnailScale.trace" but am afraid to delete that.
