Can I find my PDA number for my Samsung Galaxy s5 without turning it on?

[AC Question]

Hi,

My Phone is currently stuck on a bootloop, with no way of entering Recovery Mode (Volume up + Home + Power DOESN'T WORK) so going into settings and clicking "about" is out of the question. In order to fix it, I need to reset the OS back to the original version, yet there is at least 50 different variants for the S5, so I need the PDA number to make sure I download the correct OS and install it.

Pull the back cover, there should be some info under there somewhere.

Okay, so I'm looking at the back screen, and have the following:
Model: SM-G900H FCC ID: A3LSMG900H
SSN: -G900HGSMH
Do I need to post the IMEI number and s/n? None of this will give me the PDA number to make sure I download the correct OS.

I would suggest going to SamMobile.com and checking under Firmware for your software to d/l. Here is a link to the firmware downloads, pick the country of origin your device is from Firmware for Samsung SM-G900H - SamMobile meaning if you bought it outside of the US, you need to use the firmware that was intended for its country of origin.
