Welcome to Android Central! Are you saying that you're able to force a shutdown from that frozen screen, and then boot into Safe Mode, but the same thing happens?

No, while using my phone it turned into black screen but the white lights are on as I send the image link.

Anyways while the lights are on, I waited til the battery drains out then charged it then I able to open normally.

You can try forcing a shutdown by pressing and holding Power and Vol Down for about 10-15 seconds. If all of the lights go out, wait a few seconds, then try booting up into Safe Mode: https://support.t-mobile.com/docs/DOC-28008
