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 recently installed the latest OTA leak for the GS3 but when I continued to follow the instructions to re root and unlock the bootloader on my phone, I went into a boot loop. I successfully installed the leaked ota but I want root again as well as an unlocked bootloader. What's the best way to go about this? I'm on 4.1.1 jellybean. Thank u!

Follow section 5 of my guide...simply use one of the prerooted roms listed, then proceed back up to section 1, follow steps 8-12, to unlock and flash a custom recovery.
Can u point me to that thread? And I don't think I completely understood ur response. U said I have to choose a rom from ur list? Wut does that mean?

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!
So i have successfully rooted my droid razr m and unlocked the bootloader. i tried using safestrap to avail, i it didnt work at all. Then i tried clock work recovery flashed through with adb. It got flashed successfully. Then tried to get recovery open didnt work. I wanted to know if the unlocked bootloader message is the cause of both programs not working. or can you guys give me maybe better instructions to start flashing roms on phone on a rooted and unlocked bootloader. THANK YOU. I wanna put a rom on my device so my phones themes look cool.
I am also on 4.4.2 stock. and how do i get rid of the unlocked bootloader message.

you don't need ss any more with an unlocked bl, although it should still work. however, the version you tried probably isnt compatible with kk.
as for cwm and twrp, make sure you have the correct version for kk, and after you install it you want to boot directly into it. do not let the phone boot the os the first time or it will wipe the recovery back to the stock one. also you should grab the su flashable zip and flash that when your in recovery the first time, so you have a properly working root.
after all that you can put a rom on your phone and flash it, but make sure you get one that is on kk base or it will just bootloop.
there is a method to remove the ul bl warning, check you forums general section for the post. i know there is one in the maxx/hd forum, but i don't know if they are cross compatible.

I'm gave my daughter my old S3 for Christmas and I want to get it up to date.
It's running a Clean 4.1.2 ROM from back in the day. TWRP is like on v 1.x (I kid you not). I think the bootloader is unlocked because there is no Safestrap. It goes right into TWRP, no "slots".
I want to get her up to 4.3 at least, 4.4 hopefully. I tried to download on of the new ROMs but TWRP didn't even see it so I'm suspecting I need to upgrade TWRP first?
anywho...looking for a path to the latest ROMS...would rather not lockup the bootloader unless someone can make a good case for it.
Thank you very much in advance.
God Bless,
Matt

Yes you need to update twrp to the latest version. And your bootloader almost has to be unlocked because if it wasn't you would not be able to install a custom recovery.
I would go with a custom rom, stay away from bootloader locked roms. There's nothing special about the new TW 4.4.2 rom other than it locks the bootloader down tight, as far as roms that's your own choice but I'd do some reading before I did anything

You can grab the latest twrp here http://techerrata.com/browse/twrp2/d2vzw
Both .tar and .img files, the .tar requires Odin and you can install the .img through an app called flashify (requires root), its in the play store. After that read some of the ROM threads. You might want to also update your firmware and baseband. Most of the ROM threads will recommend this and give you links to proper firmware, making sure not to lock the bootloader.
Good luck

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
