I'm looking to update my mom's phone, I honestly don't remember what I did to it in the past. As far as I can tell it's rooted on NC5, with a lock boot loader (I assume although when booting up I see an unlocked lock with the words "custom" underneath it) and knox is 0x0. Does that mean my bootloader is actually unlocked? and am I following this guide (http://forum.xda-developers.com/gal...-to-root-i545vrufnk1-4-4-2-12-1-2014-t2959613) to update to the latest version?
Thanks
You are most likely rooted but for sure your bootloader is still locked. As far as updating, if you don't want to keep root or anything then just odin back to stock and accept an OTA. If you want root then there are other ways to update posted in this forum.
When I first received my S5, I believe I saw the option to unlock the bootloader via the settings menu. I thought it was a build that the device came with on either 5.0 or 4.4.2. I was wondering because I was wanting to download to it to see if the option was still available and if it still supported it's desired function. I just want an unlocked bootloader to be honest

The T-Mobile version of the S5 (SM-G900T) comes with an unlocked bootloader. I point this out, since you posted this on the T-Mobile forum.
Do you have a phone other than a SM-G900T?

I do, SM-G900T, but I'm not so certain my bootloader is unlocked, if it was, I would have the unlock symbol on the first boot splash screen.

It comes with an unlocked bootloader, if you're asking for the purpose of flashing a custom recovery or kernel you're all set you can do so automatically

Okay, so that explains how you can flash a custom recovery / kernel without the need to root first. Makes sense.
I was wondering if the S6 on Vodafone in the UK came with a locked bootloader, and if so how difficult was it to unlock? I have an S7 Edge on pre-order, and presume that would come locked too if the S6 did. I can't live without root. Cheers.
No one has an S6 Edge on Vodafone?

Seems so, as I have had the same problem by installing MM 6.0.1 firmware with the UK csc code VOD (appearing as BTU on phone). The bootloader wouldn't let me flash TWRP through ODIN (sorry, could flash, but not boot into TWRP, stuck on bootloader).
So i took the provided MM 6.0.1. bootloader from Carotix CarHDRom, flashed it together with at the same place provided TWRP for
MM (the old 2.8.7.0/2.8.7.1 or even new TWRP 3.0 provided on the homepage of TWRP.me , won't work on MM) throught ODIN.
Within TWRP flashed hybridmax's S5E-AELKernel_MM...kernel 1.5 and superSU beta 2.67 (previosly stored/copied to the mobile device) and rebooted - rooted and all working fine.

Did you have the OEM Unlock toggle in dev options?

Do not know if or not.
Just flashed first the original VOD 6.0.1 fw and then tried to have a working TWRP recovery, but could't boot into TWRP recover, the original bootloader did not let me... this for, bootloader and twrp from carotix (and eventually his provided kernel and/or rom) , and everything goes fine.

My understanding of a locked bootloader is that you can't flash anything that isn't official, including a replacement bootloader, which you indicate you did successfully. Otherwise Verizon Samsung customers would simply flash a new bootloader over their locked one. Ever TWRP wouldn't have flashed, it would have kicked out an error in Odin as you made the attempt because the bootloader wouldn't have allowed it. It sounds like your attempt at flashing it finished successfully, but just wouldn't boot into it. I'm wondering if this was caused by something other than the bootloader being locked.

All possible. However, sometimes we'll just have to give it a try, by using the information and software available. I do have to mention, that my mobile is/was provider-free (not locked to a specific provider). But even a locked mobile can be handeld to get
in free and unlocked. In such case, this should be done first and after that the upgrade to rooted MM and ROM, etc.
No worries, cheers for the reply. I'll wait until I receive it then simply return it and cancel the contract if it's locked.
Hi, i had the same problem. I flashed TWRP, but i could not boot to TWRP. I found that I also have locked bootloader. No OEM Unlock toggle in dev options.

I've not received my phone yet, but this doesn't look good. Were you able to disable the reactivation lock on your S6? Or, alternatively, like coco722, were you able to simply overwrite the bootloader? I'm not concerned with Knox or Vodafone's warranty, as long as I'm able to overcome the locked bootloader and root.
Hi everyone, I've just got a G-900T running 5.1.1 yesterday. This phone is unlocked, but I am not sure what method did the former user use to unlock. I want to install another ROM (maybe 6.0.1 firmware or other custom ROM), but I am afraid that it will be carrier-locked again, can anyone confirm this for me? Thanks for the help.
To be locked again, you'll have to lock it from developer options, which is not available on AOSP ROMs, and hidden from Stock-based ones. You may consider yourself safe.
There are two types of locking - 1) carrier, and 2) Boot loader. To flash a custom ROM, the boot loader has to be unlocked. That would have been the case if it had a custom ROM installed when you bought it. But if it has a stock ROM, you will have to check the security lock level (About Device) to confirm that the security level is low enough to allow unlocking the boot loader. Otherwise, you may brick your phone.

I have tried for multiple hours to get fastboot and ADB to work with my S6 Edge but it is not working. I suspect I might need to try older Samsung drivers (I only tried the latest ones as far as I remember). I wanted these tools in order to check if my bootloader was unlocked so that I wouldn't brick my device if I tried to install a custom ROM and TWRP. Anyway I followed a video and installed TWRP on my phone and installed Lineage OS Android 10 without checking the bootloader since the guy in the video did not mention doing so and still installed the custom ROM and TWRP. It is working fine. I know it is most likely that since this was possible, the bootloader should probably be unlocked but I just wanted to confirm with more experienced smartphone modders if this is indeed the case. Is it then safe to root my phone without checking bootloader?
Sub-question: If a person were to theoretically attmept to install custom ROM or TWRP or root the phone while the bootloader is locked, would that result in the root failing but the device still being usable or would the attempt result in the device being bricked? IE if the bootloader is locked is it dangerous to attempt to flash software to the phone or will it result in a harmless "failed" message, etc.?
Thank you.
