Rooted/Stock Bionic with Forever Root. Froze some bloatware with Titanium Backup but accidentally deleted HTML Viewer. Trying to reinstall it so I can do .893 OTA update. Tried putting the HTML Viewer apk and odex in System/app file via Root Explorer method. Mounted and set correct permissions but the Package Installer fails to install the app. From reading through different forums, other are having trouble reinstalling deleted system apps on the Bionic also. Is there a way to reinstall a system app or do I now need to restore to unrooted stock to get the system app back? If so, what would be the best way to do it? Would appreciate any help and advise on the subject.
