The S5 SM-G900F's bootloader is unlocked right out-of-the-box & cannot be locked.
Check the steps in S5 super clean install > Flashing TWRP Recovery on Samsung Firmware chapter.
The post includes links for updating TWRP, Modem & S5's aboot bootloader.

Hi guys
This is my situation: i have a Samsung Galaxy note 3 wich is running NG3 firmware.
I bought the phone free from the store doesn't belong to any carrier like verzion or At&t. Recently I rooted it with kingoapp, then installed supersu and busybox.
I tried to install "full screen caller id note 3" from XDA forum but I get the "footer is wrong" message in recovery mode.
Can everyone help me please?
How can I unlock the bootloader?
The boot loader should be unlocked by default...

Curiously, how do you know the bootloader is locked?
If you used kingo, the bootloader isn't locked. Kingo uses a recovery replacement based root method similar to cf-autoroot, which would not have worked on a bootloader locked device.
The "footer is wrong" message is because you're trying to flash a package that the recovery can't parse properly. Use twrp recovery, if that doesn't work, try PhilZ or cwm.

Bootloader is locked when you can't get the custom recovery menu in recovery mode, you can't backup ou restore your current rom, you can't install zips, custom roms...etc
thanks man

Have a nice day my friend
Lately, I wanted to root my GS4 (it surely wasn't an AT&T one, bought it in Russia, there is no AT&T). So, motochopper fails, CF-Auto-Root fails, everything fails! I am stuck at 4.4.2 and there is no OTA upgrade. Download mode says "MODEL NUMBER: SGH-I337", but in the "About phone" menu it is clearly stated that model number is "GT-I9500" and build number is "KOT49H.I9500XXUFNB7". Even the baseband version starts with "I9500". All the hacks I am seeing on the Internet (such as Loki) for unlocking bootloader fail, saying that my phone model is not supported. Heimdall and Odin fail to flash anything and the red text appears in the download mode: "SECURE MAGICODE CHECK FAIL". What my model is and what do I DO? I want to root it and install some decent recovery and CWM ROM.
Please, ask any questions you like and help me)
The model number in download mode is the right one. Once the bootloader on the i337 is locked, it cannot be unlocked.
A locked bootloader means cwm and twrp cannot be installed.

Why can't it be unlocked? I've seen so many guides and tools to do it. The problem is that they don't work and I don't even know my true build version to figure smth out. Why doesn't it even root like normal I337 should do? Also it doensn't upgrade to lollipop like normal I337 should.
The bootloader is locked on the i337, just like it is on other at&t phones, with no way to unlock it. An s4 bounty on XDA for finding an unlock method remains unclaimed: http://forum.xda-developers.com/showthread.php?t=2257620
The phone is an i337 and can only run stock i337 roms or customs based off a stock rom.
Safe strap is the only custom recovery available for a locked bootloader.

So, ok. We managed to confirm it is a SGH-I337. But what about Loki tool? It can install CWM recovery, but does not work on my device? Also, I ask one more time, how can I know what the real build number is? And how to root? All SGH-I337 should root with motochopper but mine doesn't. What can I do about this?
Cwm and twrp cannot work on the phone. I have never seen a post where someone has ever had it work with a locked bootloader.
I'm not sure but motochopper may not work with every bootloader and every rom. Reading through this forum, I don't think I remember seeing motochopper mentioned.
You'll have to confirm the bootloader and rom in the phone and search through the various rooting threads. I don't have access to the i337, only the i337m as I am in Canada.
Attempting to flash TWRP using Odin, only Odin keeps getting stuck at "File analysis." Please help!
TWRP can't be flashed to an AT&T s4 with a locked bootloader.
What is the exact model # of the s4? The model # can be found in download mode.

I had 3.0.2-0 TWRP on my i337 (jflteatt) for a good while now. Then yesterday I flashed the latest 3.1.0-0 and it broke my recovery (stupid me, I keep forgeting that I should not "fix it if it ain't broken"!). Whoever posted the 3.1.0-0 version "forgot" to mention that it was not lokied! Now I am trying to recover my recovery, as it were: Someone posted a .tar of a lokied 3.1.0-0 TWRP, but it looks to me that the file is bad. Can you provide a working (i.e. lokied) .tar of an earlier TWRP version please?
Does your i337 have a locked bootloader?

All ATT i337 (jflteatt) have locked bootloaders. That is why "they" came up with the loki-doki exploit.
The i337 bootloader was locked with the 4.3 or newer ROM. With a locked bootloader, no exploit will allow the installation of twrp, philz, or cwm which is why safestrap must be used with a locked bootloader. Same applies to the att note 3.

Thanks for the replies. As I said in my earlier post, I used to run TWRP 3.0.2-0 on my jflteatt, and that should tell you everything you need to know. (I am currently running LinOS 14.1 on the phone.) Only yesterday, after "upgrading" my recovery to 3.1.0-0 the trouble started. As for the bootloader version, how do you tell what that is?
Since the phone is running twrp, this tells me that the bootloader is older than 4.3 and the bootloader is not locked.
Are there any references to Knox in download mode? If not, the bootloader is not locked and the bootloader is 4.1 or 4.2.

Again, all i337 bootloaders are locked. The first generations of locked bootloaders were vulnerable to the loki exploit. Newer generations of bootloaders are not so vulnerable.
And just to answer my initial question, TWRP cannot be flashed w/Odin on i337 (jflteatt), regardless of the bootloader version, as the bootloader is locked. I had to flash TWRP from within the OS after rooting. Problem solved.
I've rooted and flashed ROMs on several phones but this is my first time on a Samsung device. When I did this in the Moto X Pure I had to unlock the bootloader before installing TWRP and flashing a ROM, but I'm not sure if I need to unlock my bootloader in this phone since I already flashed TWRP and rooted through ODIN.
Do I need to unlock the bootloader to flash a new ROM? (TWRP installed and phone is rooted)
The phone is a SM-G900F running stock 6.0.1 btw
No.

1) Download the Stock ROM for N910V
2) Got into Download (Mode Power + Home + Vol Down)
3)Flash the downloaded firmware via Odin
4) Reboot
5)Repeat Step 2
6)Flash CF Auto Root for N910V Via Odin
and you are done
Note: This is all only possible if there is a CF Auto Root for N910V or of there are other methods of rooting N910V but since you are already on custom I am guessing there is

You might want to flash a "safe" firmware instead of the official one. If you use a non modified firmware it's going to lock your bootloader again and you'll have to do the bootloader unlock procedure again.
Link to safe firmware- this one has the bootloader removed so it won't lock your phone again. Flash that file in Odin and then flash this file using Twrp.

Can I just flash this file if I want to unlock Bootloader? I mean like download and flash this safe firmware via Odin, will that unlock ? my Bootloader?

No, unfortunately not. The "safe" firmware doesn't contain the bootloader (aka the aboot.mbn). Therefore it won't replace your currently locked/unlocked bootloader so no changes would take place either way. So whatever state your bootloader is in before you flash the safe firmware is what will remain after flashing.
I don't know if I'm making this more confusing for you or less. Let me know if I need to explain that better.
