Hey everyone, I've been researching for days, trying to figure out how to Unlock my bootloader on a 4.2.2 OS d2vzw(Verizon SGS3) SCH-I535. it seems the only way I can start flashing new roms( specifically CM 12.1) is to install a custom recovery such as TWRP or CWM, but it locks up my recovery and I end up flashing the stock 4.2.2 over and over again. are there alternatives ways to flash roms? is it impossible to unlock my bootloader on a 4.2.2? is there a way I can downgrade my bootloader? help please nothing is working and I can't find current information....Thanks.

I'm assuming you mean 4.4.2 or 4.1.2. There is a huge difference between the two.
If you are on 4.4.2 you do not have the option to unlock the bootloader.
However if you are on 4.1.2 you do have the option to unlock the bootloader. There never was a 4.2.2 update for the VZW S3.

http://www.mobiletechvideos.com/samsung-galaxy-s-iii-s3-bootloader-downgrade-service/ I should start a thread with this LOL. This guy is the only guy I know of that can do it. It's done by soldering a jtag in 3 spots all within millimeters of each other. I've sent a bunch of business his way and never saw a bad review

So I recently got a SGS3 for verizon and I was looking to install CM10 on it. On the CM wiki it says that "CyanogenMod on the Verizon variant of the Galaxy S3 you need to load an older bootloader."
I'm not clear to whether this means I just need an unlocked bootloader (which I have now from EZ Unlock) or if I need an entirely different bootloader, because looking at some forum posts for the official CM10.1, it only mentions that I need updated CWM or TWRP.
Any help would be appreciated.

I installed it without modifying my bootloader, just rooted, unlocked and flashed CWM then flashed many CM ROMs (10 nightly's, 10 stable and 10.1 nightly's)
root. unlock bootloader. download rom manager from store. flash away in recovery.
do a search, theres guides EVERYWHERE.

There are guides everywhere, but they don't mention the need to flash an older bootloader, yet the how-to guide on the cm wiki says to. A little odd don't you think. I just want to get my facts straight before I turn my 2 day old sgs3 into a brick.

What they mean by the older bootloader is to unlock it. The way we unlock the bootloader is with a leaked EC build that was never officially released for our phone. So just do what others are saying, backup your imei/custom recovery/root/unlock bootloader and flash away
Thanks, that cleared up things for me.
But one more question, I didn't accept the OTA to JB when I first got this phone and I'm still on ICS, can I go from ICS to JB or would I have to accept the OTA/ flash JB through odin first?
This also applies to if I wanted to go from jb to ics. Can I just flash an ics Rom over a jb Rom or is Odin required.
I'm currently on Android 4.1.2 using Baked 6 and I want to upgrade to Baked 8, or anything on 4.2 for that matter. If I update a ROM, does this also mean it updates my bootloader? If not how to I properly update my bootloader without bricking my tablet? I've been reading around but there's so much data on the forums that I feel like I'm going to accidentally make a mistake

No flashing a custom rom will not upgrade your bootloader, only the stock asus firmwares will do this or a custom made blob file.
There are several methods to upgrade your bootloader to a JB 4.2 bootloader which can be found here or here. I prefer using the fastboot method for upgrading but up to you. Just make sure that once you've upgraded your bootloader to a 4.2 bootloader that you flash a -4.2 version of twrp or you will brick. I would suggest upgrading to JB 4.2 - 10.6.1.15.3 & twrp 2.5.0.0-4.2 as I find this more stable than 10.6.1.8 & twrp 2.4.4.0-4.2
If using the fastboot method and you need any help with any step just let me know.
Currently my phone is on 4.1.2 bonestock ROM with [VRBMF1] and I believe the bootloader is unlocked. I've been out of the loop for so long that I dont know what the best way to get to 4.3 is while keeping my root and bootloader unlocked. Any help is appreciated!

First, a caveat: Android 4.4 was just released for our phones a couple days ago, so you may want to wait a little while and see if any ROMs based on it come out. As of right now, there isn't a rooted version available, so 4.3 is your only option.
If you're on Bonestock, your bootloader is in fact unlocked. You can flash any of the 4.3 ROMs you find in the Android Development section. You should update your recovery first, I use TWRP version 2.6.3.0, the newest version is 2.7.1.0.
You should also flash the newer modem for the phone, VRUCML1, first, you can find that here under the Modems folder: http://d-h.st/users/invisiblek/?fld_id=35604#files. Only do that if you are actually going to update to a 4.3 ROM. Then you can flash any ROM you like: CleanROM 8.2 would be my pick, there's also Alliance and MOAR.

Thank bud, this is exactly what I needed!
A customer brought his phone and he tried to flash on his own, he did not unlock the bootloader. I've tried to flash without unlocking the bootloader but have no luck getting back to stock. Since the phone will not boot into a usable menu I cannot unlock the bootloader. I have done a lot of research and cannot find a flawless way to do this. Is there anyone that has a direct way to fix this. Photos attached are when the phone is booted up normally, and in download mode. Thank you in advance.

Unfortunately, the bootloader cannot be unlocked on your customer's Verizon S3. Based on the Dropbox photos of Download mode, I'd wager that phone was on KitKat 4.4.2 VRUDNE1 before they attempted to modify it. That software comes with a locked bootloader that has not been unlocked. VRUDNE1 4.4.2 is the only software that can be flashed on the phone using Odin. Flash the VRUDNE1 tar in the PDA section of Odin and it *should* allow you to boot into the rom after it has flashed the firmware.
What have you and also the customer attempted to do to the phone?
Edit: I believe Odin 3.07 can be used, if not then you would need a newer version of Odin for Windows computers.
thank you very much, that got me back to stock at least. I appreciate the help! Next I need to wait for the 4.4.2 bootloader unlock if it ever comes out. Thanks again!

To be realistic, there won't be a bootloader unlock method on this phone any time soon. The phone has been bootloader locked since 2013 OTAs without an unlock tool found. The only thing you can do is use Safestrap which hijacks the boot process and allows the user to dual boot another VRUDNE1 4.4.2 TouchWiz rom. Our version of Safestrap requires the stock VRUDNE1 4.4.2 kernel in order to boot another VRUDNE1 rom. They also need to flash VRUDNE1 kernel modules in order to have working wifi as well. All the info you need can be found here in our sticky: http://forum.xda-developers.com/showthread.php?t=2639337
This means no AOSP roms, no custom kernels, no using roms on 4.3 or earlier, and as stated before no bootloader unlock.

Hi!
I have a Samsung Galaxy SM J100H with KitKat 4.4.4 that I would like to unlock the bootloader on.
The only tutorial that I can find online tells me that what is given will only work for a stock android ROM but not a custom like my Samsung touchwiz.
Does anyone have any suggestions?
Thank you!
Sadly to see you've got no reply from anyone on here! I am also having the kind of your phone and I really need to unlock bootloader. Although I already have root on it.

I don't think it matters that you're on a custom ROM, custom ROMs don't change your bootloader, it still has the stock bootloader you had before you flashed the custom ROM.
Either way, you can flash back to full stock via Odin then follow the instructions you found. Then flash TWRP the flash SuperSU.zip in TWRP to root, then you can flash custom ROMs.
