Hi all, this may be a stupid question, but being as the att S4 has the locked bootloader, is it possible to flash the att S4 with tmobile software/firmware via odin and then unlock the phone to be used on any carrier? Or can this not be done because of the boot loader? Thanks in advance!!

When using a rom from another Galaxy S4 Variant, you cannot flash 1. The modem/radio/baseband 2. The bootloader (PRL, SRL, ABOOT...)
Also if your device's bootloader is locked, it's likely that you cannot swap the Kernel either.
According to some people however, the Modem can however be swapped IF you are using the same base model (example SGH-I1337 modem can in theory be swapped with its SGH-I337M variant). I however have not tested this myself so you will have to make sure of it before trying.
Keep in mind that on Qualcomm revisions, the baseband is actually the very first link to the chain of trust so messing with it can potentially brick your phone.

I was wondering, is there a locked boot loader on the Rogers Samsung Galaxy S4 (Canadian Version)?
I am wondering this because if I go to root my phone, it could brick it, and I wouldn't like that....
So, please help. Thanks.

to the best of my knowledge, it is the ATT version that has the locked bootie. You should be able to easily root your device using this file.
good luck!

Okay, I was just wondering because if i do root my phone, and it has a boot loader, then it will possibly brick it.
I also just want to make sure that there isn't a boot loader, so if anyone else has any knowledge, please post below. Thanks!

Well all phones have to have a bootloader. But I337m, which is the Canadian version, definitely has an unlocked bootloader. So you will not get any issues with CF Auto Root or anything.

Okay, good. Now I just have to make sure I have the correct CF Auto Root for this phone, which is SGH-I337m.
Hi,
I have a Sprint L720 (Baseband: L720VPUFNG2) phone. How can I tell if my bootloader is unlocked or not? I read a number of posts here on XDA and unfortunately could not find an answer that was relevant to my case.
Is there any way to get the bootloader information for my L720? Could someone outline the steps how to get that information (locked/unlocked)?
thanks!!

Thanks so much!!!
I am thinking on rooting my L720 and read on Chainfire's page that if bootloader is locked then the root might brick the device and just wanted to double confirm my bootloader is unlocked...
Thanks again,
only VZW is locked
I can't figure out how to do this at all. I know it's online somewhere, but for the life if me I can't figure out where. Someone please help!

You have to sell your phone and buy an i9505. Then you can install TWRP or CWM on your Galaxy S 4.
I believe the ATT version of the s4 has a locked bootloader so flashing TWRP or CWM is not possible atm.

Is there any way to perform a nandroid-style backup/restore then?
I'd like to flash the latest stock ROM but would like a return path to what I currently have now if things go badly.
I would check out the Verizon s4 forum to confirm whether your bootloader is locked. If it is locked, there's very little you can install in terms of ROMs. Not sure about TWRP or CWM.

It's easy, if you have updated your phone to a newer version of Android, then your BL is locked.
NB1 4.4.2 is My Official ROM. I Updated It To NJ4 4.4.4 Using Android System Recovery And Then I Updated It 5.0.1 Lollipop Via Same Way.
I Think My Bootloader Is Locked.
Bootloader on LP is definitely locked.
So What Should I Do "audit13"
Once the bootloader is locked, you will need to use safestrap to flash files. Also, you'll be limited to tw-based custom ROMs.

Now I'm Looking For Galaxy Note 3.
So What Model Number I Should Buy Which Can Be Rooted Easily And Has Unlocked Bootloader.
I believe the att version of note 3 also has a locked bootloader. Get the T-Mobile version or the Canadian version.

Hi Dude.
Whats Up?
I Have Bought Samsung Galaxy Note 3 (SM-9005)
I Have Rooted It But I Want To Downgrade It To It's Official ROM And Than Update It Step By Step After Rooting My Device.
Whats Your Opineon About.
All you need to run OTA updates is use the unroot option from the root program and have a stock recovery. OTA updates will not work on a rooted system.
The quickest way to update your phone to the latest ROM would be to flash the lastest stock ROM from sammobile and then check for OTA updates.

Will the Galaxy s4 i9505 new stock lolipop firmware work on my SGH-M919 Tmobile Galaxy s4?

If your phone is unlocked, it should.

im not sure what it being unlocked has to do with that but maybe you can educated me about that, but ya it is unlocked i just unlocked it actually the other day by flashing the mdl modem and using the regionunlock app then flashing back to nb4 modem it worked like a charm on my t-mobile sgh-m919 s4 now im using at&t service
btw if i odin update firmware with i9505 loli or like sgh-m919 ok3 will it lock back my phone or is it permanent even the way i did it?
btw you dont sound to sure about it i dont want to brick my phone have you done this before?
i know the i9505 roms work i flash those all the time but im just not sure about the firmware.
Update: I found this what do you think??

Hey all.
I've a question. In GT-i9500, is there the need to unlock bootloader as in Motorola devices before flashing custom ROMs. Or it comes with it's bootloader pre-unlocked?
Would be very glad on your response
Thank You!

in I9500 we can update bootloader and go back to old without problems and we can flash roms without need to unlock
Verizon and AT&T devices usually have locked bootloaders. Everything else should be unlocked.

Then we should first of all unlock bootloader before flashing roms?
Unless the S4 is a US model sold by AT&T or Verizon, which yours isn't, the bootloader will be unlocked. That means being able to update the bootloader, radio, and installing custom ROMs, as previously stated. Keep in mind the following: Samsung does not use fastboot, thus any commands you could use on a Motorola device will not work on a Samsung device. You will have to use Odin.

I-9500 came with factory unlocked bootloader.
If your phone really is i-9500 as you said,
install the custom recovery like TWPR or CWM via odin and
flash the custom rom of your choice via the custom recovery.

Ok thanks
l have a question if my i9500 says secure download enabled does that mean its bootloader locked +++
Asked and answered already in this thread. Unless your S4 is an SGH-I337 or SCH-I545 (AT&T and Verizon respectively) your bootloader will not be locked.
