[Q] Back to Verizon - Verizon Samsung Galaxy S III

I was recently informed that I might be able to get into the Edge Program with Verizon and have run into a dilemma. I am obviously rooted and cannot return my phone to my phone as is but if I am accepted into the program I will most likely have to trade my S3 in for whatever other phone I want. I have found other topics but haven't really gotten an updated answer. I need to flash my phone back to stock so I can potentially return it but all of these other rest guides don't tell me how to get the 4.3 update that the GS3 officially comes with if you were to buy it today from Verizon. Any help here?

But what if I am ineligible for the Edge and want to return back to root? This is telling me my bootloader will then be locked forever.

You asked how to get to 4.3 as of it were Ota'd by Verizon, that's the 4.3 update.
You can reroot but you can't unlock the bootloader, you should make sure you're eligible first before you flash that.

Ok sounds good, thank you! Another quick question though, is there even a point to re-rooting but having a locked bootloader? Or is rooting again useless after that?

I want to know am I able to root and ROM this thing? I've done it to many phones before. It's not locked down or is it?
Thanks!

You're definitely able to unlock and root this baby. The latest JB OTA just makes it slightly more difficult to unlock but it's still possible. If you get it and it still runs ICS, unlock and root and don't take that OTA.

The last time I checked all android based phones have a method to root and this phone is no different. If you check both android development sections you WILL see ROMs there to flash. Also if an android phone comes with an locked bootloader then there is a method to unlock it. This phone comes with a locked bootloader but there is an app for that.

If there was only like some sort of forum-like site that would give you that info....that would be pretty cool. One can dream though. :silly:
Thanks to an African-Canadian Sock Monkey, we can unlock the bootloader.
a quick look in the development thread would of answered this, but yes, it's VERY simple to root and ROM this phone (coming from HTC phones)
Very simple - did mine while sitting at work goofing around...There's more and more ROMs available every day and you can get support for ANYTHING from all the awesome people here. I'm new to modding phones and I'm so impressed
Just an added note to thank all at XDA Developers who helped my unlock and root my HTC Thunderbolt and my current Galaxy S3.
There's really little need to root and flash the S3 other than to remove VZW's bloatware and I appreciate that but XDA Developers are essential to the Thunderbolt, it required rooting and flashing to make it function properly!

I have to disagree with that statement. Rooting and ROMing, is absolutely necessary, if you can't stand SuckWiz.

How do I unlock the bootloader on S3 running 4.2.1?

I have searched far and wide and cannot find a bootloader unlock method that will work with the Galaxy S3 that has already been updated to official 4.1.2.
The EZ-Unlock app will not work for 4.1.2 (only 4.1.1 and before)
The open1your1eyes0 method that was updated in February 2013 does not work either: http://forum.xda-developers.com/showthread.php?t=1974114
What do I do? Until I get my bootloader unlock I cannot do anything.
Phone is currently Build Number: JZ054K.I535VRBMB1

Hi all.
I finally had to do a factory reset on my Verizon GS3. Poor performance and yellow factory mode text floating on screen.
I have obtained root access on the phone, however ODIN3 flashing a recovery image fails. My understanding is that I need the bootloader unlocked for that to work. Is there a reliable way to do that?

Your bootloader is locked forever, unlocking isn't an option.
If you want anything other than stock you'll have to use Safestrap recovery and modified stock ROMs like everyone else with locked bootloader Verizon S3.
Safestrap is deprecated. At least their site says dev. Has stopped. There's probably a fork of it on github somewhere, but any safestrap you find won't be by the original developer.

I don't know, I use the Verizon S3 ROMs on my device but it isn't a Verizon device, but I spend a lot of time in the Verizon S3 forum, I see new users looking to customize their device all the time.
Here's the download for it

Read this thread though, if you have encrypted your data, it will cause bootloop. Yes, it isn't supported anymore, BUT, the Safestrap still available still works.

I use it on Straight talk, my device is a Straight Talk S3 SCH-S968C that uses Verizon towers, my motherboard is actually stamped with the Verizon SCH-I535 model number, its rebranded as Straight Talk's device. Only difference is they disabled the 4G on the Verizon S3 when Straight Talk rebranded it.

No, you can't flash AT&T firmware. That would surely brick your device. You can port the AT&T firmware somewhat easily, they are mostly the same but have different modems and a few other minor differences. I can link you to a thread for porting the US S3 variants.
No that's alright I'm on a note 3 anyway, but I've got a good place to start so thanks!

[Q] Switching to Cyanogenmod on 4.3 Verizon Galaxy S3

Hey guys, new to the whole Android modding stuff so, go easy because my knowledge about all the technical stuff is pretty limited.
So, anyway, I got tired of Touchwiz and I want to switch to Cyanogenmod just because I like the stock Android look and dislike the general slowness of Touchwiz. Problem is, I took the stupid OTA 4.3 update which apparently added the Knox bootloader which is, as far as I have read, impossible to unlock at this point.
I was under the impression that, with the Knox bootloader, its impossible to have a custom ROM since it will brick your device, but these threads :
http://forum.xda-developers.com/showthread.php?t=2575977
http://forum.xda-developers.com/showthread.php?t=2541343
Seem to indicate that all the Knox bootloader does is prevent downgrading the bootloader and also voids the warranty if you tamper with your device. Well, my warranty expire a couple months ago so I couldn't care less. But now I'm really confused. Can I, or can I not flash Cyanogenmod on my 4.3 Verizon Galaxy S3 assuming I don't care about the warranty?
You will brick your fone flashing any type of custom recovery or roms will brick you fone. U can root ur fone from my understanding from other threads but thats it

Like what was said above, you can't install any custom roms.
Knox is not responsible for locking the bootloader, it's only a flag that is triggered when root is achieved. Think of it like a flash counter that can't be undone. It has nothing to do with this.
The problem is the bootloader that was also updated. Every step in the chain has to be on the VRUCML1 base or the phone will brick itself and terminate the boot. Since our previous unlock method was to modify a step in the bootloader to unlock it, it can't be done the same way on the new base because it isn't able to be modified.
Any attempt to unlock it by any means or flashing a custom rom will change the bootloader. Safestrap is the only hope for the new base, or unless we're lucky enough to get a leaked unlocked bootloader.

Like the original poster, I am stuck on a touchWiz android 4.3 verizon gs3. I have been able to root it with safe root, but I have not had any luck rolling back to 4.1.2 or to unlock the bootloader. I have seen various "how to" type things that are supposed to work on 4.3, but like I said, no luck so far.
If someone more knowledgeable than myself has heard of a breakthrough in this area that would be awesome.

I was running cm11 m3 on my vzw galaxy s3 but used odin to install VRUCML1 not knowing about Knox and all the fun that comes with that. Before I installed VRUCML1, I did a backup. I've since regained root access through saferoot but cant boot into a custom recovery without getting the "you've been naughty. go visit a verizon store" error message. Does anyone know of a way that I can restore my pre-VRUCML1 backup or am I out of luck since my bootloader is still locked?

There was a link for something like that posted some time ago here at XDA, and if it's the same link it is for the international version of the S3 not our Verizon version. The Verizon version cannot be flashed back to a previous firmware.

Last Unlocked Bootloader?

I'm searching for a Verizon GS3 with an unlocked bootloader. Are all 4.1.2 versions unlocked? What baseband version am I looking for?
Sent from my SCH-I545 using Tapatalk 2
Technically all phones from the factory would be locked. But everything below android version 4.3 can be unlocked. So your options are:
1. A locked phone on a version of android less than 4.3.
2. A device that had beenpreviously unlocked and upgraded to 4.3 with a custom ROM.
4.4 is currently completely locked down.
So basically, if I can find one with 4.1.2, I can upgrade with the MOAR rom to 4.3, and still keep unlocked bootloader? It is based on ml1. I loved that rom with Sprint, and want it again

If your bootloader currently unlocked, you could flash any custom rom and you should be fine, just don't ever flash stock 4.3 or 4.4. They will locked you down ....forever..
Sweet. I have a guy checking his other stores for a 4.1.2. He thinks he has a few. I'm gonna trade my GS4 with kitkat straight up. That's how bad I want MOAR. I've been flashing roms with Sprint for over 4 years. This locked bootloader is a new beast to me

Forgive me, I spent my life with Sprint, and didn't have to deal with this stuff. Can android version be downgraded without changing the bootloader? Or can any bootloader be unlocked running 4.1.2?
ask him/her what firmware the phone is on. That will tell you everything. ML1 is what you are looking for. That is the last firmware, we have that's compatible with unlocking.

ML1 is 4.3. That firmware is bootloader locked. You're looking for MB1 or MF1 4.1.1 or 4.1.2.

Yes. There is an MSM Tool in the guides section of the 7 Pro forums of XDA. there are actually 3, but you're looking for the one to revert back to stock T-Mobile firmware.

yeah I've been keeping my eye on that ever since i decided that i was going to get this phone lol. i just wasn't sure if it was possible to turn the phone back in without them knowing I've tampered with the phone.
Yep, it's possible to go back to stock. But I've been with T-Mobile for years and have turned in every phone I've had rooted with twrp installed. They've never given me any issues.

If I recall correctly, it'll even relock the bootloader, though you could just relock it yourself before using the tool to make sure. There's no flags tripped or anything like Samsung's Knox counter.

I've done this with at least 4 phones and never had an issue either.
No one seems to care/know if the phone is unlocked and/or rooted...
