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.
Okay, so I'm looking at the back screen, and have the following:
Model: SM-G900H FCC ID: A3LSMG900H
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.
