[Q] Rooting an SM-G900H of undetermined origin - Galaxy S 5 Q&A, Help & Troubleshooting

Hi!
A friend of mine asked me if I could root his SM-G900H device and install a Google free ROM.
Dumb as I am, I said yes and yesterday he told me that the phone may be an imitation.
But how to figure that out? I got the attached screenshot but I am not familiar with Samsung devices and I never rooted one.
Is it safe to root this device?

Someone Please help a newbie!

ok so I purchased a note 3 recently from a friend and I am at the dreaded 27% install issue people are having for kitkat.
The phone does say custom upon starting with the open pad lock, upon checking a root checker app it seems the phone is not rooted.
I is a att phone, does this means it is unlocked? it also says under version 4.3 so i dont think its a custom rom?
My main question is, if I take this phone to bestbuy to a samsung hub will they update it for me to kitkat even with the padlock open on my startup screen?
Please keep in mind im totally new to android so any help will be appreciated! thank you!

There are bunch of how to root on the forum or look on YouTube. As for your question I have the same device model and had no problem rooting it. Or in other words it will work fine if you follow the instructions

You own a Frankestein. Install this APP and add some screenshots.
@androidfine16: Without seeing your information from Phone Info, I can virtually guarantee that your only means of upgrading will be to install AT&T firmware, which will not lead to a good experience unless you're not planning on rooting the phone. AT&T locks its bootloader, making rooting virtually impossible.
If you just got this device, run, don't walk to where you got it from and return it.

Urgent, System Software Not Authorized by Verizon

Hi, recently i purchase a Samsung Galaxy S5 G900F online, turn out to be Model SM-G900F but Build is G900V, so i went to upgrade to lollipop using Mobile ODIN Pro and now i'm stuck at the verizon warning startup. I know i been cheated but i really need the phone instead of go through all the refund process which take days or weeks. I been trying to put it back to where it could be functional but i failed. Please is there any solution can guide me through this nightmare. I really really need the phone to be working again. If is does not appear to have Lollipop then the older version is fine by me too. Please anyone~~~~~~
