How Can You Tell If the Bootloader is Locked? - Galaxy S 4 Q&A, Help & Troubleshooting

Canadians are starting to get their phones shipped and in hand. What is required to determine if the bootloader is locked? Anything in download or recovery mode? Does an attempt to use Odin need to be made? If so, just connecting to it or actually flashing something?
Any help would be great so I can pass it on and ask others. I'd like to figure it out before my phone ships and to also save others from ordering if it is locked. Thanks.

If you try CF-Auto-Root (http://forum.xda-developers.com/showthread.php?t=2219803) it'll simply fail and do nothing if your bootloader is locked.
The real way is to goto Odin Mode and look for "CSB-OEM_CONFIG_LSB: 0x30" which means you're locked.

so that means,if CF-root works on my i9505 then the bootloader isn't locked?
EDIT:
CF-auto-root(http://forum.xda-developers.com/showthread.php?t=2219803) works on my phone,however if I go to download mode I've got this line there "CSB-OEM_CONFIG_LSB: 0x30".
Any idea??

You ran it and it really worked? Did you test to see if root was actually enabled? If your phone is locked, root isn't available after trying CF-Auto-root

If you have an i9505 then you're definitely unlocked anyway =)

Actually I should recant that. Someone else had that line AND he got root.
So you have to try CF-Auto-Root and see if it does anything.

CSB-OEM_CONFIG_LSB: 0x30 does not mean that the bootloader is locked, in fact the lock status does not appear anywhere in the download mode and is defined by a gpio state triggered from a Qfuse. None of which are visible through any interfaces available to the user.
Keep in mind however that even though your bootloader may be unlocked, the bootloader itself PBL, SBL... needs to be signed, otherwise it will not be overwritten. The kernel's signature however will not be verified by an unlocked bootloader. So far all consumer GT-I9505 appear to feature an unlocked bootloader, with the exception of few engineering and review devices.

[Q] Is Sprint SGS4 Bootloader locked or not

I'm confused at this point. Consensus seems to say that the AT&T boot is locked.
What about the Sprint one? Is it locked too, or do we not know for sure yet?

At&t has been confirmed as being locked. The Sprint version is not locked, at least not in the historical sense. We have been able to Odin Kernel, Recovery and System with no problems. We are not sure yet what the Write Protection means.
Good summary. AT&T's locked bootloader crap cost them a customer this weekend.

[Q] S4 MF3 Sim unlock??

I've for a AT&T S4 I337 with the MF3 update. I have already managed to root it. Is there any way to unlock the sim?? I have searched. Tried to get to the service menu and it does't let me do anything. Can I flash another rom or do something so I can unlock it.

Seeing how you are on the MF3 currently there is no way to flash another rom or custom recovery, your best bet would be go through att to get the unlock code.
But it won't even let me get into the service menu. I tried the codes and process they say online and it does nothing. Can someone explain why it won't budge and how and when it will be fixed?

The service menu unlock was disabled in MF3. You have to get an unlock code from your carrier or another service.

Theres not even a place to enter an unlock code. I cut my Straight talk sim with the proper tool and inserted it and it didn't even recognize it. Still says "no sim inserted." Going to try to buy a ATT straight talk sim from the Straight talk website next.

I ported my # over from AT&T today to Straight Talk. At first it didn't like the new sim card, but after my # was ported and a few reboots the message didn't come up anymore. I now have phone & data service running on it, even though I was still under contract for a previous device (S3). I called AT&T and after a lengthy call, they said I didn't need an unlock code if I was getting service OK from Straight Talk. My old APN info is still there for them along with the one I created for 'ST'. I have no way of deleting the old APN, and who knows where, or if I'll get updates from. My only other option was to get the Google Edition S4, but I payed full price for the one I got now. Hopefully the bootloader issue will get cracked before long and I can get this ATT crap off my phone for good.
Network lock
I want to share something, could get passed the first screens all the way down to the network lock menu, no sha off options.
Haven't seen any posts regarding this.

Ok, isnt that region lock thread just for Galaxy Note 3s? and on MF3, doesnt seem like the service menu will come up at all, so kinda curious too how people are making that work.

Hey did you guys talking about region unlock or carrier unlock?
Can you please share steps you followed, it will be a great help.

It's been mentioned that region unlock has had a positive affect on the Sim unlock.
However Sim unlock and region unlock are totally different from one another.I used the free unlock method when I was MDL and only used the region unlock with MF3 .will I ever really know if the region unlock worked?probably never.
I am still Sim unlocked

galaxy s4 sgh I337 at&t unlock

Hey there, I have a samsung galaxy s4 sgh-i337 locked to at&t.
I bought an unlocking code from an ebay user.
it doesn't unlock my phone, it writes: "unlock request unsuccesful". I tried to use the defreeze code and then again the network code, still nothing.
I was referred to a guide that suppose to show me the "service mode menu", by entering *#0011# . so service mode goes on when i put that number in the dial pad, but then I suppose to do 'menu key'->'back'->'menu key'->'key input'->'1', but after I do that nothing happens, the service mode menu with all the options doesn't pop up, it stays in the same page of the service mode. somewhere down on the ServiceMode page it writes "Service:Limited". what should I do?

Someone... Help.. please
no Mega genius here that can solve my problem?
same boat here man, this is a new problem since not everyone has 4.3 yet. Att won't even give me the unlock code since they changed eligibility few months ago to "only off contract or fulfilled contract phones." I've read one person saying the eBay unlock code didnt work on 4.3 either. And the only success i've heard is another post here on XDA saying they unlocked 4.3 using the regionlockaway app, but they apparently Odin flashed 4.2.2, did the regionlockaway while the phone had no sound/wifi etc., then Odin flashed 4.3(locked again), then flashed 4.2.2 odin again, regionlockaway'ed, then odin'ed 4.3 again and the unlock stayed. That sounds ridiculous and is not an exact science.
So i'm done with At&t's phone slavery and switching to T-mobile on a nexus till the Xperia Z1 is out. I thought this was the future.

Is there any one rooted S7/S7 edge Snapdragon version?

My English is bad, sorry.
I have rooted my SM-G9350(S7 edge China version) by flashing xiao1u's recovery, then boot into recovery and flash SuperSU 2.71.
Then I found the front camera issue: When using system camera app's auto mode, the second and next photo captured become deep red black, when reboot or reset the camera app, the first shot is well, but the second shot is still become deep red black.... And other problems, such as in some apps the video can not play directly, the picture stoped at begin and the speaker make "da da da"...(I have asked one who have not root his phone, he does not have this problem...)
So I flashed back offical firmware using odin, seleted "Re-partition, Nand erase all and phone bootloader update", but no any change, the problem still there...
Some one flashed xiao1u's recovery but he haven't boot into recovery to flash SuperSU ZIP package, he say his phone does not have these problems...That seems says xiao1u's recovery does not directly cause these problems...
So the problems may because using xiao1u's recovery flashing SuperSU package?
Some one guess these problems because root changed param partition, who have param.bin?
Not only me, as I found there are about fifty people have the same problem as me....
Who can give some help? Lots of thanks!!!!!

So far, apparently.
It's been my limited observation that locked bootloaders are carrier specific, it may be that the US providers may have become consistent but I haven't really made an assessment.

I thank Congress. You know. My lawmakers, which are lock-stock-and-barrel owned by the well monied PACs, such as the telecom providers.
I give a second thanks to the malicious coders of the world that have made it necessary for personal devices that do computation to have strong built-in security defenses just to be able to communicate with other drives.
I used that file to unlock (by some way) my bootloader im on the same g9350.
The people with the locked BL issue should try CROM, if it doesnt work it will not kill your phone.
1400700226 can you share to me the links from where you obtained the info related to the root??? As I mentioned you before when i tryed the root my IMEI got corrupted.

It worked. Thanks!
Will this allow it to be used on straight talk?
I wonder if a Sprint HTC Bolt can be unlocked for Boost? Appears same hardware.

depends if u need your MSL
to root you 1st need to unlock the bootloader via htcdev.com
after unlocking bootloader, you need to flash TWRP from download mode
boot into TWRP to flash either Magisk (my preference) or SuperSU

Yes.
HTC Bolt SIM-Unlock
I followed the steps from the instructions and was able to SIM-Unlock the phone.
Also, performed UICC unlock in Software Updates after I paid off the phone.
I tested it with a friend's T-Mobile SIM and worked flawlessly.
Also tested with another friend's AT&T SIM and again worked flawlessly.
I have since switched to Verizon and found out that it will not work on Verizon, so I decided to sell it.
Sold it on eBay and now the guy who purchased it says he is getting the following error :
"GSM/UMTS Mode not supported in the U.S. Only foreign SIM card usable in device. Your device will switch to CDMA mode now."
When I google this error, everything I find is for older HTC devices, and these posts are back from 2011.
Has anyone come across this, or do you think this guy is trying to pull a fast one on me?
Again, I know for a fact it is unlocked and will work on AT&T but he says it is still SIM-Locked, and says the MSL code I gave him is incorrect.
Pretty sure a phone cannot re-lock itself.. am I wrong?
