Tizen Developers

Hi experts. To most of you guys here I'm probably Kind of a noob. So forgive me if this seems a noon question. But..... Where are custom apps and wgts installed on tizen devices..... I've started a script to back up and restore apps. But need some help. I've found 4 folders to pull and push. The problem is when I push them back on a clean install I'm stuck at a black screen at boot. I've tried removing any system apps from these folder locations prior to pushing. But still not successful. If you can head over to this link. And have a look it will be very much appreciated http://forum.xda-developers.com/gear-2/orig-development/custom-app-wgt-backup-dev-t2900599
