and downloaded windows 10 and after i did a hard reset everything is erased even the icon settings and messages icon and the store icon..what can i do?
To begin with lumia 630 is unsupported for windows 10 upgrade, as you must have made some registry tweaks to get the update through insiders which includes installing a build or OS version made exclusively for different device. This might cause major issues t your device or could bring up some minor glitches as you are facing now.
For now , perform another hard reset and see if that helps. If not roll back to windows phone 8.1 .
