Hi arief240,
Thanks for posting! We see you may want to try Quick Start a second time because not all of your data transferred. It's definitely important to have all of your files on your new iPhone, and we're happy to help.
You might want to start by double-checking this resource to see if might help before you try Quick Start again: About missing information after you restore your iPhone, iPad, or iPod touch with iCloud Backup. Depending on whether your files were part of iCloud or if they were part of a backup, you might be able to resolve the issue using the steps above without using Quick Start.
Otherwise, you should be able to do Quick Start again by erasing or restoring the iPhone. This process would remove everything added to the iPhone by the previous Quick Start process and anything added since.
Here's how:
Restore your iPhone, iPad, or iPod to factory settings
Use Quick Start to transfer data to a new iPhone, iPad, or iPod touch
We hope this helps to get you set up so you can enjoy the new iPhone SE.
Have a good one.
