iPhone 5S stuck on 2G, 3G & LTE won't work

Anyone can help me?... I'm previously using iOS 8.4 on iphone 5S and it went well. After a weeks, iOS 8.4.1 pops up and ready to be installed on your phone. So I did it, Then I kept changing from 2G to 3G to LTE and back to 2G. After a while I've noticed something went wrong on the data, it won't never comes out on 3G & LTE. it just kept searching on 3G & LTE and it just stucks up on 2G. Is there anything that I could resolve this problem?

Here's I've done on my phone:

Change Airplane mode to On & Off, no to avail
Reset network settings, no to avail
Reboot phone using sleep & home button, no to avail
Reset all setting & Erase all content and settings, still no to avail.

Would this possible to downgrade to iOS 8.4 to resolve this problem? I'm really tired of kept resetting my phone.

Thanks,

JoeGonz
