So yesterday I flashed XTRSense188.8.131.52 to both mine and my wife's Eris. My phone has been running great with no problems whatsoever. This afternoon my wife calls me freaking out because her contacts have disappeared... all of them. She said they were all there this morning and all of a sudden they're just gone. I told her to go to Settings, Accounts/Sync, and to Sync Google but that didn't help. She rebooted her phone, synced again and still nothing. Finally I walked her through the process of rebooting into recovery mode, wiping cache, doing a factory reset, and finally a NAND restore which got her back to pre-XTRSense and all her contacts came back without issue. What could have caused this issue and what can I do to prevent future occurrences? I'd really like to flash XTRSense back to her phone because it seemed to fix her other issues but not if its going to cause more problems than it fixes. Any help would be greatly appreciated.
