Recently, I messed up real bad and I accidentally installed the firmware of a Verizon GS3 on a T-Mobile GS3. Now it is a Verizon phone :c I already rooted it so I can replace the firmware with a T-Mobile TouchWiz Stock ROM. All I need is the last step: to unlock the bootloader. Can someone (or anyone) please help me remove it? I am currently mentally constipated by the problem and I just have only a couple steps until I return it back into a T-Mobile Galaxy S3. Now that's the question. Here's the story of how it is what it is right now.
So one day, I was rooting my phone to install CyanogenMod because I wanted something similar to 4.2.1 Jellybean. I did everything except I didn't delete the Dalvhik Cache. So when everything was loaded, I see that my phone cannot open the PlayStore. In my mind, I reflect back a couple minutes in the past just to remember I didn't clear what I needed to. Idiotic me goes off and attempts to erase CyanogenMod 10 and I get stuck in a boot loop. I am in a state in which I call "mental constipation". I then accidentally and foolishly install the Verizon GS3 ROM and BOOM. I am in a worse situation. Fast forward today, I root the phone but as a Verizon Galaxy S3. I am almost done but I need to just unlock the bootloader and I am set to return it back into a T-Mobile GS3. So, can someone please tell me how to unlock the Verizon GS3's bootloader?
tl;dr turned T-Mobile GS3 into a Verizon GS3 and I need to unlock boot loader

Dear sir:
I have rooted my AT&T SGS3 following mskip's method. But all supervisor files went away when I woke up. I've done this twice. The second time at&t make my phone unbootable.
Can anyone help?
Months ago, before the 4.3 OTA, I attempted to unlock the bootloader and root my wife's Galaxy SIII on vzw. The phone seemed to be bricked, but I was able to recover it using one of the available unbrick utilities. From that point forward, on boot it displays "Custom ROM", but is not rooted and I cannot boot into recovery at all. To make things worse, my wife accepted the 4.3 OTA before I could warn her not to and it has since upgraded to 4.4.2 OTA. Is there any option to still unlock the bootloader, or are we stuck? Also, if I can't unlock and root the phone, I would like to be able to return it to stock, but nothing so far has worked.
Hi,
I just got a gs3 a few days ago with verizon and read up about what I could do with it.
I have root with supersu, busybox, terminal emulator and safestrap.
I wanted to flash cm 11 onto it, but with the new OTA Update from Samsung earlier this year I found out it was impossible with Knox and Verizon locking it down.
However, whenever I attempt to run roms flashed using Safestrap such as eclipse the boot sequence goes Press power button -> Vibrate once -> Release power -> Vibrate -> Samsung Galaxy SIII screen -> Safestrap -> Black Screen.
I don't know what I'm doing wrong, but nothing is working at all, is there a rom I can use? (preferably with an UI similar to that of CyanogenMod's KK) or am I stuck with Samsung's UI and Verizon's bloatware?
I also saw a lot of TW but I don't know what the people in the forums are talking about when they mention this.
Also, forgive my ignorance on the matter of programming and such but, is there a way to unlock the bootloader?
I hear it's encrypted and locked by Verizon. Is it possible to write a new firmware over the Encrypted Verizon one and use that instead?
Thanks for even reading this, A reply would mean a lot to me!

Its now bootloader locked and no you can't unlock it. Your stuck with a permanent locked bootloader. You can however flash BL(bootloader locked) roms via safestrap
And no you cannot run a new firmware other than the safestrap bootloader locked ones
From my CM11 S3
Have a samsung galaxy s1 i897 'captivate' from at&t phone.
Phone originally bought outright, didn't use for years, now trying to unlock so that a friend can use it.
First updated to the pacrom custom rom with kitkat 4.4 (is this part of the problem??) to test/be sure it would work before reenabling the phone. Got the unlock code from at&t - copied it exactly and it's FAILED now 3 times in a row, afraid to touch it with two left.
Is being under 4.4 part of the problem/does it have to have factory rom?
Asked some samsung people who suggested it may need to flash back to the original factory rom, but even thats not enough, mentioned "triangle" to "set back the clock" to pretend it's never been rooted or run a newer OS. Suggested it should then unlock. But also suggested certain Samsungs of this era were notorious for just not unlocking even with everything perfect which is why I was asking here before using up my last 2 attempts.
Does this all sound right/can only unlock the phone from the original factory ROM and OS version? Once unlocked when I update to PacRom/kitkat 4.4 I assume it stays unlocked or will it create a problem somehow?
If for some reason the last remaining 2 chances bite it, I assume this is what people normally mean by bricked and hopefully there's a recovery process or does locked to at&t forever really mean that?
So what I want to do is switch this phone to straight talk but want the att bloatware off this. If I install unlocked firmware and root the device would that make it unlocked? Like not carrier locked. Straight talk said I can already use a Sim despite it being locked but I wanna unlock it myself.
I don't think att will yet and not sure if they will at all. I'm converting my chapter 13 bankruptcy to a 7 on Tuesday and att bill is rolled into it so the phones will be mine once that is discharged but not sure if they will unlock them right after or if it will take months,that's why I'm asking this. I already reinstalled att firmware on this phone because I tried to install a custom room and messed up due to the bootloader issue of it being v5 I think.
