Can my Samsung Galaxy S5 G900A (AT&T) be rooted?

[tony19950725]

I have a G900A samsung galaxy s5 with android 5.0 and the build number is LRX21T.G900AUCU4BOF3 that I would like to root. Is there any good programs or methods to root my phone? Thanks

You can downgrade it to 4.4.2 (https://www.sammobile.com/firmwares/database/SM-G900A/ ) and root that. See [Samsung] How to flash Stock ROM via ODIN.

Or you could try Kingroot (the on-phone device version).

I am afraid that the AT&T model of the Galaxy S5, G900A, has been un-rootable for more than 2 years, since the launch of Android 4.4.4. You cannot downgrade to an earlier firmware or use Kingo Root, etc; because of AT&T's own mega locked down bootloader. See #1.6 of 42 Galaxy S5 models - Dummies Guide and At&t is there still no root
