[Q] Unlocked bootloader/roms - Galaxy S III Q&A, (US Carriers)

so i understand that all 3 carriers at&t,tmobile,&sprint including the international version of the galaxy s3 all have unlocked bootlaoders besides the verizon model.the international i think i read up that when you buy it the bootlaoder is unlocked already.i have the tmobile version of the galaxy s3 and is there a way of checking i have a unlocked bootloader or if not is there a way to unlock it? & if i do have a unlocked bootloader can i flash roms from the international threads?
if these questions have been posted and answered already im sorry

Agreed, I bricked my T-Mobile Galaxy gs3 doing these roms, lucky I found a place to unbrick it. Stick to the Samung development thread. For now.

Hi all, just have a small question to ask, will international atrixes (Korean in my case, should've gone for ATT Version) be able to flash CM7 or MIUI or similar custom rom when its out, or its build only for ATT Atrixes?

As long as you have an unlocked bootloader, then you will be able to install them. The only catch is you will have to apply a RAM fix.

[Q] 2.3.4 question

I have a rooted photon 4g sprint edition running 2.3.4 and i want to know if there are any custom roms that keep 4g. I have not unlocked the bootloader or made any other changes to the phone yet. I have unlocked and rooted a few phoes in the past and had no problems but i have not found a good answer to this problem anywhere. I'm sorry if this is a repetative question but there are too many maybe answers out there. So basically 4g with custom rom yes or no? Please help
There's a thread in Dev section were you use pudding to unlock then relock to regain 4G.

Android 4.3 Unlock Bootloader?

Hi all,
I looked around and it seems to me there is currently no way to unlock the bootloader on the Verizon Note 2 w/ 4.3 Jellybean installed. I have my phone rooted, but I would really like to install CM. Do any of you know if we're getting closer to a method to unlock the bootloader? Is there already one? Will we never get one? Just an update is all I'm looking for. Really appreciate all answers. Thanks a lot!

Actually, that downgrades your phone to a version that still has the unlockable bootloader, it doesn't unlock the 4.3 bootloader. Granted, that the end point is essentially the same, it is a different methodology.
My actual bootloader version is I605VRALJB (4.11). I unlocked long ago with Adams original method...pre Casual...lol. So being able to go back to the 4.12 bootloader would be a good thing for people stuck on 4.3 and locked bootloader. It would allow the flashing of ROMs and custom recovery...the end goal...as you mentioned, but ...true it is not a 4.3 bootloader unlock....lol

Check it out, they can do it and what a great job they do. I just got mine back from then and it was on 4.3 OTA with locked bootloader. Now I'm on 4.1.2 and unlocked bootloader. Just flashed kitkat and TWRP . Josh will treat you right.

[Q] Unlock the SIM for Omni 4.4.3

I have flashed my Verizon S3 to Omni KitKat 4.4.3 version. I am thinking Bootloader is locked means it will unlock this SIM too.
If not how to unlock the SIM to use other carrier. Is there any app for unlock the phone?
Wrong forum, this is for the i9300 only.

Depends on the exact model. AT&T (G900A) and Verizon's S5s have the bootloader locked, but T-Mobile's (G900T) is not at this point. With TMO's S5 you can root and even install some ROMs without tripping Knox if you are careful. But if you install a custom recovery then Knox will trip. Although some say tripping Knox is not a problem. I tripped it when I installed Phil's touch recovery and have flashed many ROMs with no issues. I'm currently using Omega Rom and have no issues at all. I'm using a G900T on AT&T. The G900T has all the same frequencies and LTE bands as the G900A, plus a few special ones for TMO, but most importantly, no locked bootloader.
