G900F Bootloader - Galaxy S 5 Q&A, Help & Troubleshooting

Ok, so I'm technically a new user on XDA although it's not the first time I've read through things here and been relatively successful with rooting and flashing different ROMs. I made an account recently because just reading is no longer helping me
Anyway, I'm trying to unlock the bootloader on the Galaxy S5 G900F model. I've been able to install Philz Touch Recovery and gotten root access, but I still can't flash a ROM because the bootloader is locked. I can't seem to find a method, specifically for G900F, but I've tried several methods already including the following:

https://forum.xda-developers.com/ve...t/rd-unlocking-galaxys-s5-bootloader-t3337909
- All 4 methods don't work which isn't surprising since this is for G900V, the Verizon one.

- Same problem as above, it's for G900V
Twrp, Root And Bootloader Unlock For Samsung Galaxy S5 - Droid School
http://www.droidschool.com/twrp-root-bootloader-unlock-samsung-galaxy-s5/
- This one just frustrated me because I knew the fastboot method didn't work on Samsung phones, but I tried it anyway.
I've also tried using the CF-AutoRoot flashed through Odin, but that ended up failing too.
If anybody can point me in the right direction or something, it would be very much appreciated.

G900F is int'l, so its bootloader is unlocked from the factory. G900V, the verizon model has a locked bootloader. Decide if you have a G900F or G900V.

Verizon note 4 unlocked on Cricket (AT&T) network custom rom

I'm new here but have been following xda for years. I'm not new to rooting or flashing custom roms but after a few days of searching I can't find an answer to the following question.
I have and unlocked Verizon Note 4 n910v running Android 4.4.4 on the Cricket (AT&T) network. If I'm going to install a custom rom, do I need to find a rom for Verizon or for AT&T? Also can anyone clear up the rumor about a locked bootloader on this device? Any help would be awesome!
If you have already unlocked the bootloader on the 910V, I'm not too sure what rumor you are referencing regarding a locked bootloader ::
As far as roms go, it's a Verizon device so you need Verizon roms and firmware.

For ROMs, you must install verizon ROMs because the phone uses verizon-customized hardware.
It is no rumor that this device comes with a locked bootloader. However, thanks to the talented devs here at XDA, there is now an official way to unlock the bootloader; but you have to update to Lollipop 5.1.1 and BPA1 baseband.
I'm using a T-mobile sim in my verizon note 4 without unlocking the bootloader on lollipop and BPA1, so you shouldn't worry about your sim not working after updating. Have fun!
you have a misunderstanding of unlocked. what you are referencing is that you are using the factory unlocked gsm portion of the modem in the verizon model phone. you are NOT bootloader unlocked as you are still on 4.4! if you want to truly unlock it (as in the bootloader) then you will need to upgrade to 5.1.1 (BPA1) via odin. There are several tutorials on how to achieve this, and unlocking (including one that i wrote on the main thread).
to answer your question about using a verizon rom or a t-mobile rom, you can try any snapdragon rom that you would like, but there is NO GUARANTEE that they will work as each developer compiles with or without certain components. what ever you do, do NOT try to flash other carrier (at&t, t-mobile, sprint, etc.) firmware. BIG NO NO! although you claim to have experience with rooting and flashing roms, i would advise you to ALWAYS stick with the carrier variation of whatever device you are working with until you get a better understanding of the different components to a phone i.e. bootloader, modem, rom, etc. xda-university has a nice explanation of these things. so go read up on these things. if you need help, feel free to ask.
Thank you for everyone's advice. Upgrade to lollipop via Odin and bpa1. Got it. As far as custom rom goes, use a Verizon carrier custom rom.

Customizability of S7 Edge

I used to frequent XDA back when I first bought my Galaxy SIII. I was struck by the whole issue with the OTA update locking my bootloader, and pretty much stopped following XDA, since it was declared that there would be no way to flash custom roms or recoveries.
Well, my phone is on it's last legs and I'm looking to upgrade to perhaps the Galaxy S7 or the S7 Edge. Do these phones, (through Verizon) still have issues with locked bootloaders?
Yes, no bootloader unlock for any US models. There is root however and you can use an app called flashfire to flash things, even some ROMs(follow instructions carefully)

GALAXY S5 SM-G900S bootloader

Hi, I own a rooted , carrier-unlocked GALAXY S5 SM-G900S outside korea. I want to install TWRP and flash custom roms but i don't know if my phone bootloader is locked before i proceed. I've searched through the forums but couldn't find any relevant answer.
I basically want to know if the GALAXY S5 SM-G900S has a locked or unlocked bootloader ?
and can i proceed to install twrp/flash custom roms?
Your bootloaders is unlocked just make sure the OEM unlock is on in your developer options.
Thanks

Questions About Bootloader, Rooting, and Custom Roms on G930V

Hello to the XDA Community, I recently made this account and would like to get some help from the great people here.
I own a Verizon Samsung Galaxy S7 G930V. I, unfortunately, found out the hard way that it could not be unlocked because Samsung decided to lock down the bootloader on it (something that they were a bit more lenient with on the Galaxy S8, I think?). Either way, I was reading this XDA article (https://www.xda-developers.com/galaxy-s7-bootloader-lock-explained-you-might-not-get-aosp-after-all/) about the bootloader, and it basically says that, despite the OEM Unlock option being available under Developer Options, nothing that doesn't have some sort of official signature can be flashed to the device, so it's basically pointless.
But, then I saw that LineageOS dropped official builds for the Galaxy S7. My only question, therefore, is: why would Lineage OS drop custom ROMS for a phone that cannot have anything flashed to it? Am I missing something? Not sure what I'm missing. Just to clear things up again: I have the Verizon Galaxy S7 G930V (Snapdragon). I am also using a T-Mobile SIM in the phone, not sure if that matters or not, however.
So, what I assume is that somehow people were able to get past the bootloader and that is the reason that LineageOS released official builds of their ROM. If that's the case, is there a method/tutorial for, first, unlocking the bootloader and rooting the Verizon G930V, and then installing the custom ROM successfully? Also, I see that LineageOS does not have a build for the G930V specifically, so would it brick my phone if I installed the build for the G930S, for example?
Thank you guys! Bare with me if I completely missed something please!

There are numerous variants of the GS7 and GS7E that have a bootloader that can be unlocked. The Verizon version is not one of them. There is no way currently (and likely ever) to unlock the bootloader on the Verizon version of this phone. This is the case with almost every Verizon phone. People are finding this out the hard way with the new Google Pixel 2's...all versions other than the Verizon one you can unlock the bootloader. It's a Verizon thing and it won't change. You'll need to buy an unlocked phone capable of running on Verizon's network bands if you want this kind of stuff on Big Red.

You have a snapdragon version that has a locked bootloader, there is no current standalone root method, if you have the latest bootloader installed then the mentioned methods you've used won't work as they haven't patched it yet. Blame the network providers for all this.

5th digit back from end is bootloader revision there is now a method of rooting nougat only. No oreo or pie. Fortuanatly the method installs safestrap where you can flash a nougat system img. Su and busybox. On top of a revision 5 combination nougat bootloader. Look up s8 safestrap edl
