That doesn't mean your bootloader is unlocked. This can happen when you root too.

Lol no way (yet) to unlock..
mf3 rooted

Just like Whizzpopper said, if you are rooted that will cause the Custom screen to show when you boot. You have to unroot. I know Rom Toolbox has a feature that would allow you to change that screen to a custom picture/animation, but not sure if it is compatible with the S4.

Not neccessarily unlock for boot mine stayed the same till I ran wanam xposed last night, which I some what regret I think one of the changes I made (1 too many perhaps lol) messed me up I get fc for xda now when trying to give thanks reply or w.e..
Any1 kno how I can make a comma stay permanant on the stock keyboard?
mf3 rooted

Try Triangle Away to get rid of the custom screen and rest the flash counter.

[Q] Galaxy S4 At&t Shows Unlocked Bootloader Screen on Bootup?

I might just be stupid but when I bootup my Galaxy S4 on At&t it shows an unlocked padlock as if it were unlocked. Underneath it shows the word "Custom"
Does this mean anything????? Please respond...
I'm guessing you rooted your phone as I have the same thing. I believe it's just a splash screen png when we rooted. I also installed the blue crysis theme so I replaced my systemui.apk.

It means you should probably "search" before posting. This information exists in several of the "Root" threads that already exist. Just search the forums and it'll tell you all about it...well, as much is as known about it at this point. Good luck.

did you root with a certain root method? cause where you read how to answers this question...numerous times..why start another thread? anyway the answer is it was stated when you root that would be there..means nothing..as soon as you flash your first rom it is bye bye.
Oh OK sorry in didn't see that

CM/AOSP roms will not be working on the ATT variant until the bootloader is unlocked. For now you only get to use TW roms via SafeStrap

You say until the bootloader is unlocked. Do you truly believe that Samsung and AT&T are gonna get off their money making high horse and actually allow an unlocked bootloader? That's why the "developer version" is there. I hate this crap. I have rooted and flashed roms for every damn phone I've ever owned. Sigh..

He's talking about the community. Until someone in the android scene unlocks it. It's not up to Samsung, it's up to AT&T.

can you flash custom kernels?

is it possible to flash a custom kernel on the s5 even though it has a locked bootloader? i was looking online and saw that some people were able to do it with other phones but they said it varies on the phone itself and the kernel

No, it won't work on our Verizon/At&T model. It will work with t-mobile and sprint and Verizon Dev edition. Dev had banned the project so everyone is moving on to ktoonsez's kernel, which again worked on everything except for our Verizon 900V model. Bottom line, you can't flash a custom kernel onto a locked bootloader. We have many variation of model S5, make sure you are looking at Verizon (SM-900V) and AT&T (SM-G900A) which have locked bootloader.

Sprint S7 unlocked: Is there a way to update it safely?

Long time reader...first time poster
I bought an unlocked sprint s7 from ebay and it works like a dream and i was wondering if there was a safe method to update the phone WITHOUT ruining the unlock that the seller put on the phone.
Current software is update PC5 and i would love to benefit from security and bug fixes in new releases.
Thanks in advance!

I always thought if a phone gets carrier unlocked it didnt matter what u did to it, it would stay unlocked. Unless the way he got it unlocked was thru a mod maybe that can b ruined. Im not sure

Most likely not a carrier unlock do to a unlocked padlock during boot animation as well as samsung pay not working due to software mods that im guessing made it unlocked in the first place. Thanks for the reply!

Bootloader unlock and sim unlock are two different things. You said it has an unlock pad on boot up screen. That means it's bootloader is unlocked. Which means if I am correct if it has a custom recovery you are unable to do future ota updates. Can and possibly brick your phone. You can flash a ton that has the new update no issues developers are usually fairly quick to update there rom on the latest ota.

Now my question is that since my phones bootloader is unlocked via custom software, would it be safe to root it and install custom roms that have the current updates? thanks

Yes! You are in the wrong forum though. You are on sprint but need to be with the enxyos forum ND running their tarp and roms
Have the same dilemma as OP.
unlocked on PC5 firmware with GCPro. No root was used
Should i update OTA or leave it be.

I can confirm that updating over OTA will NOT screw with the unlock of the device. If your samsung pay does not work i would disable knox with a package disabler app to receive samsung pay in you new updated state.
OTA update from PC5 to PH7 on unlocked phone went smoothly.
Thanks
I have a unlocked Sprint S7 but im outside of America, is there any way i can update without losing the unlock? i don't want to end with an expensive brick.
Im stuck in G930PVPU2APC5 and i can't receive OTA updates
I bought unlocked sprint s7 that I'm using with metro PCS, but it's not letting me update the profile and because of that I'm not getting the wifi hotspot option. How do I get it to work?
@ThaDunder : You must initially do it manually over samsung smart switch then OTA will work @zirnitra : Sadly wifi tethering is not working for me either...no idea how to fix it =/ must be a symptom of the unlocking like wifi calling
