What exactly does the locked bootloader prevent? - Verizon Samsung Galaxy S III

Noob question I know but I've tried reading up on the subject as much as I can - I still don't fully understand what exactly the locked loader does to this phone (aside from making it more difficult to root) and would really appreciate a brief explanation.
As I understand now the phone can be rooted, ROMs can be loaded (but they have to be specific to the VZW S3 right?), and full recovery options as well. Basically wondering what the disadvantages are and if they're more significant than just a little more work to root/mod the phone? Much thanks!

It prevents root access, you know jail breaking. You can't control your rom. You use the one provided to you by Verizon with all their bloatware. You can't change what software was delivered to you.

A locked bootloader is ultimately intended to prevent you from potentially costing the carrier $money$ by:
Bricking your phone and then playing dumb when you return it for an exchange. (people on xda opening admit to this kind of fraud. kinda sad. you brick it you keep it!, or buy another)
Modifying your phone and then blaming bugs on the carrier. A support vampire.
Assuring content providers they've made exclusive deals with that their content is "secure".

Great Question!
If your phone was a Windows 7 computer....
If you rooted it, you'd have an account with Administrator access.
As for the bootloader... Suppose you wanted to upgrade to Windows 8, even though it hasn't been authorized by your ISP, on this Windows 7 computer with a locked bootloader.
You cant, c:\windows is locked. If you change anything in that directory, your Windows 7 computer will start, but only to display "Invalid System Software Installed! Please shutdown and return this computer to your ISP's store for assistance."
What we have on Verizon, is a phone with admin rights (rooted), where we can't re-install the software needed to boot a different operating system.
If you're interested in more detail on how the hardware prevents the bootloader from being cracked, and what the attack vectors are, you might be interested in the presentation linked from this post http://forum.xda-developers.com/showthread.php?t=1766638
(And yes I know that c:\windows isn't actually the boot partition on windows. Just trying to make it easier for the OP to understand.)

Thanks that really helped. So in the example of Jelly Bean -sounds like we need to wait for Verizon to release a version of it? Do all custom ROMs as well have to be based off of the VZW file that checks ok with the bootloader?
I'm really only concerned with Jelly Bean (knowing how long VZW takes to release stuff) and that wifi nag screen, I want to punch someone in the nose every time i see it...I will check out that presentation over lunch, would love to learn all about the details.

interesting and helpful topic.. however.. i thought i understood the locked bootloader situation on my droid bionic i could flash any rom i wanted to in conjunction with bootstrap wich i believe to be a bootloader by pass based recovery but no kernals were able to be flashed that is what i understood to be a locked b.l was not overclocking or custom kernals maybe i was wrong this whole time..

Weird this is how i understood it as well. I'm coming from the Droid X2 and thanks do DK we had cm9 up and running with ICS but the bootloader was locked down. I took it that bootstrap is a recovery tool that works in a way of when your phone is off and you plug it in you boot up to the bootloader. This would allow you to re-flash a rom if your current one was corrupt.
So in my mind you can run different roms and different android versions its just harder to get them on the phone. But from what i've seen you cant flash a new kernal if the bootloader is locked.
Maybe i miss understood this if so i really would like to know fully how this works

On the verizon gs3 the locked bootloader is keeping us from flashing a custom kernel thru odin...we can root and flash a custom rom / recovery but it has to utilize the stock kernel currently. Our bootloader debacle is nothing like moto devices and I wish folks would stop comparing the 2!

Exactly, what a locked bootloader will allow you to do will vary on different phones and firmwares. I've known some which would not even allow you to flash a recovery.

2.3 rootable? Maybe not? Who knows....

Has anyone thought that maybe google has made 2.3 unrootable? Scary thought i know, but its kind of like a cat and mouse game with the developers and google/manufacturers with root patches.
Maybe google finally will put the nail in the coffin here?
WOOT. It's rooted, im happily wrong.
It's a developer phone, so why would Google want to make devs waste time trying to root.
could it be possible that Google enable root access by default, then?

Definately not.
Dev phones have always been rootable, i doubt that will change.
The phones that have trouble being rooted are always manufacture customized ones.
it's still able to fastboot oem unlock from what i've heard. Will be rooted same day it's available for purchase guaranteed.

You are correct.
Samsung never locked their (Android?) phones. Personally I've installed custom ROMs on the Galaxy Spica and international S and both came factory unlocked. Unlike with some of HTC's devices you can flash anything you want without using exploits.

Your right, as of now I don't think Samsung locked any of their phones, but the only thing Samsung has on this phone is the hardware aspect. All the software aspect is by Google.

Then how do you explain threads like this (on the samsung galaxy sub forums):
[HOWTO] [REF] [FAQ] [Guides] [Tutorials] Flash/Root/ADB/ROM [MUST READ!]
It seems like you have carrier/sim lock and root confused. Just like nearly every phone on the market, they are locked. You will also need root to do anything that says "please root your phone". They do not ship this way...
I'm sure it will be rootable... Google doesn't want to block out developers
Just food for thought i guess, we cant know until its released anyways.

that's unlocked for carriers with gsm...that's not root. Simply meaning it will work with at&t or tmobile by changing the sim card. Root lets you edit system files and a custom recovery to flash roms
Lmao no one so far in this thread should get one of these developer phones as you plainly do not understand what you are doing here when it comes to deciding what the difference is between root permissions and unlocked to all networks.
lets put it this way, if you are one of the above who are having trouble, dream on and steer clear from the prospects of rooting all together
unless that is you fancy yourself a very expensive paperweight?

This command unlocks your bootloader on the N1/N-S allowing you to flash custom roms, but visibly voids your warranty (bootloader screen shows that it's unlocked)

Q: Vzw - unlocking the bootloader

I like all am excited about the bootloader finally being unlocked. Question is if it even matters. When running the batch file does the zip folder or file need to be on the phone (memory/ext sd card) to run it. I did it right from my windows desktop and it ran fine and finished but not sure if it really did anything.

Unlocking the boatloader will keep this from being the backwater of the Galaxy world. Now the d2vzw is the best phone on the best network in the US, without any reservation. In the really short term we won't see any difference, but it will lead to more developer interest. Developers can build ROMs for the device using the skills they already know without the hassle of learning Kexec and a different boot process. It'll allow official CyanogenMod support, and hopefully more cross-pollination with the other US GS3 variants. So yes, we wanted this.

[Q] Unlock bootloader on XT926 rooted after JB OTA update 9.30.1

I've successfully rooted my Droid RAZR MAXX HD with stock firmware version 9.30.1, but I can't seem to figure out how to unlock the bootloader.
The one catch with my phone being rooted is that it always ends up in fastboot when it boots. A simple
Code:
fastboot continue
fixes the problem, but I was wanting to flash CWM Recovery to install CM.
I have a working su/Superuser.apk, but I can't seem to fix the bootloader dilemma.

As Jhal said, you can't "fix" your bootloader, it's locked since you're on the newest OTA and it can't be unlocked. With that being said, your phone is not booting into fastboot because you're rooted. It's booting into FB because you tried to flash something that didn't work. What other things have you done or attempted to do, besides rooting? This will help us help you, the info you provided is pretty vague.

I have done absolutely nothing beyond rooting it, installing Superuser & SuperSU (both through a script I can attach, but I'm on the wrong computer), and backed up a slew of apps.
This first begun when I modified the script to fix a bug in it (ash in JB 4.2 doesn't have a -f switch in rm, and the script had a 'rm -f'). If that bug didn't exist, then it would've still happened the first of several times (I attempted it about 4-5 times, but only the last caused this). The rm -f was actually doing effectively (with successful root privileges) 'rm -f /system/install-script-2.sh', but the script actually had another script to be put into it at the location /system/install-script.sh.

Looks like you either flashed a fastboot or used a tool that used the command "fastboot oem fb_mode_set" which causes the phone to boot directly into fastboot mode. It can usually be fixed with the command "fastboot oem fb_mode_clear".

Didn't work. It is still booting there on its own upon start-up.
Also, I will mention that I did commit an act of stupidity: trying to flash against a bootloader that I couldn't verify was unlocked yet. I stupidly ran the command when I wasn't even 50% sure that it was unlocked yet (and is likely the cause of all my problems):
Code:
fastboot flash recovery <cwm-file>.zip
I'm trying my hardest to avoid sending this to Motorola just for them to charge me for the replacement, saying I've voided any warranty that exists with the phone. I have the original firmware to flash just in case, but I don't have the Motorola fastboot (for the dev editions).

First, there is no Dev Edition Fastboot....the closest would be Bell ICS since Bell shipped unlocked/unlockable Atrix HD's.
You don't flash zip files with fastboot flash.....Why is this becoming an issue these days?* The kernel is "fastboot flash boot boot.img"
*just thinking out loud
EDIT: Just realized that this was the RAZR HD forums.....just replying to quoted posts this morning....Not sure about RAZR HD Dev Edition fastboots....

The shame is, I never cared about unlocking the bootloader, as I prefer to stick to OTA's, but I do require root. So that's all I've ever done. I'm successfully rooted with the locked bootloader on 9.30.1, but it seems (at least as far as I've read on here) that I'm stuck there as I can't go anywhere else and maintain root. Would love kitkat, but root is essential.
Um, you can unlock the bootloader and still stick to OTAs.
Being able to root at any time and use custom recovery is reason enough for me.

I in no way implied I was AVOIDING unlocking due to the desire to stay on OTA's - just that I had no reason to pursue unlocking. This is the first android device I've had that ended up with a sunset where you couldn't unlock it at pretty much any point, so i never had a fear of taking the OTA and losing something in the process. If i had expected that, I certainly would have unlocked prior to 9.30.1 being installed. I honestly have yet to figure out why they don't release a program that would allow unlocking the devices - I'm not sure the manufacture's fear of unlocked bootloaders and root, as any program they release would be loaded with disclaimers - and frankly, it would allow easy restorations to ANY firmware version by service staff at verizon/at&t.

Well, in actual reality, the XT926 was never meant to be unlocked. It was only unlockable via an exploit, just like obtaining root for locked devices is an exploit in the security of the OS/device.
So, there never really was a "sunset" for unlocking this device as it wasn't meant to be. Only after the exploit was found did a patch come out to stop that exploit from being utilized on any remaining unlocked phones, current or future.
So, when there is an exploit to unlock a device, your best bet is to take advantage of it immediately.
When I got my RAZR HD, it was as a warranty replacement for my OG RAZR MAXX. When I fired it up, it stated there was an OTA available. I immediately told it no and then went straight to the forums here and on another site to investigate what my options were. When I found out that there was the possibility of my unlocking the bootloader, I immediately went to where the tool was and downloaded it. I then proceeded to read and then ask questions on if my phone couldn't unlock, would it hurt it. SamuriHL helped me out a great deal and that is how I found all his tools and how much help he provides. If it weren't for him, I wouldn't have discovered that I could unlock my bootloader.
Usually, I investigate the phone I'm interested in to see if:
1. Can the bootloader be unlocked (or is it already unlocked)?
2. Is there a known root exploit IF the bootloader cannot be unlocked?
3. What are the ROM options (safestrap, cwm, twrp recovery)?
It's definitely something I normally would look into, but I didn't know that I was going to receive the RAZR HD. Once I discovered the possibility of unlocking the bootloader, I was hoping beyond all hope that it could happen and it did. How I received a replacement phone that wasn't patched to the latest OTA was beyond me, but that is the reason I refused the OTA when I first fired up the phone. I had already read about other "horrors" of people taking an OTA and then finding they couldn't root or do other things with their phones.
Lesson learned is, NEVER take an OTA until you've fully researched what it does and what it might prevent.

I have a doubt about my bootloader

First of all sorry if my english is not clear, thanks in advance.
I bought a Z5 C6603 in a commercial store, I mean it doesn’t come from any cellular provider company. The first thing I thought when I get it was about rooting it and I did, and I did install TWRP too, but before doing these two things I unlocked the boot loader, in fact as I know if this device comes with the option of bootloader unlock: no, that means the rooting and custom recovery are not possible.
If that is true something happened because when I checked up the service menu after rooting and twrp this option tells me the bootloader unlocking is not allowed. My memory is failing because a have been working in several cell phones despite the fact I’m not an expert. I think in the process I install a kernel or a rom wich made the modification, could It be possible that this kernel change the value?
I have the ver. 32.2.A.0.224
I cannot be imagining being without the possibility of changing Roms
That is odd indeed. But since you've already unlocked your BL, what does it matter anyways what your phone tells you?

How To Guide Rooting the SM-F711B (on Version F711BXXU2AUI4) working

First of all:
I'm no Dev...just someone who likes to play lego.
From this point of view everything I post here is taken from somewhere else in the Internet and used by your own risk.
I've read a good startup here.
Hopefully this makes this thread clear enough so that i dont need to describe the whole procedure step by step.
(https://www.naldotech.com/root-samsung-galaxy-z-flip-3-5g-magisk/)
(1.OEM-Unlock,2.BL-Unlock,3.extract boot.img,4.patch boot.img via magisk on the unrooted mobile,5.patch boot.img.tar to AP&BL via Odin, 6.pray)
Anyways...here are maybe small hints to avoid a few traps.
a) Just do the oem-unlock in the dev-options (enabled by tapping buildnumber 5 times) is just half of the rent.
Afterwards i had to go in Download-mode (switch of mobile, press volUp+volDown and connect PC-cable.)
There appears a possibility of choice.
Press VolUp short: get the mobile on standby to flash the rom via odin.
Press VolUp LOONG: get the mobile to the menu where the bootloader can finally get unlocked. (Otherwhise every try to patch a rooted img will be blocked by bootloader-protection.)
Of course this can possibly be done via adb/fastboot commands.
Funny side note: OEM-Unlock-option will completely disappear from Dev-options and waranty is lost. Also the mobile stops to get Updates OTA which means that you have to update manually whenever a new version will appear in the net.
b) patching boot.img via magisk should work as described in many other magisk-rooting-manuals.
Flashing the tar back to the mobile via odin was little bit tricky.
It doesnt reach out just to provide the magisk_patched.tar to Odin just on the AB-line.
I had to patch it to BL too.
Cheers

When you boot into bootloader after unlocking, is the message something about "a custom OS can cause critical problems"?
As it stands now, the only reason I have to believe the US bootloader can't be unlocked (or isn't already) was the lack of an OEM unlock button and some cranky kid on the internet saying it hasn't been possible since the S7.
It doesn't make sense why I would have a warning about a custom OS if there is no possible way to install one, though.
@boot into bootloader after unlocking it...:
Yess you are right. Thats exactly the message.
Then you can enter the Device unlock mode again (long press VolUp) to lock bootloader again (then it resets automaticaly to factory-defaults and all work is gone.)
or
continue to flash something (short press VolUp).
Dont know about the US versions. Could be that there is a difference to my EU-models.
But either i rooted nearly every every mobile since the S2

I think you misunderstood what I was asking, but ended up answering it anyway.
It seems the message about installing custom OS versions may be a boilerplate for the bootloader, not any indication that it's possible.
naldotech.com, the link you provide is pretty clear about the process. What it doesnt say is what to do at the end. When you untick "reboot" in odin, and you finish flashing, your phone will stay in download mode. Then what to do?. Press power and volume down to leave and restart the phone? or, power and volume down, screen goes black imediately power and volume up, enter recovery and restart from there.? please someone ?
Press the power and volume down buttons for about 7 seconds and it will reboot

The USA version (snapdragon soc) can't be rooted as far as I know. There is no way to unlock the bootloader in dev options, at least on Verizon and that holds true even if you bought a unlocked phone. As soon as you insert a Verizon sim and the phone updates it's all over.
I had the same issue with the original Pixel. I bought it unlocked but before rooting it I allowed it to update like a fool. Luckily my son wanted the same phone so I gave him mine then rooted and installed TWRP before putting a Verizon sim in.
Back to Samsung...as far as I know you haven't been able to root the USA version since the note 8. The rest of the planet gets the Exynos SOC but we get the snapdragon and no root method works. My note 9, 10+ and z Flip3 didn't have an unlock bootloader option even before putting a sim in it.

I think you misunderstood what I was asking, but ended up answering it anyway.
It seems the message about installing custom OS versions may be a boilerplate for the bootloader, not any indication that it's possible.

I have to be a little skeptical when my rooted Note 8 came out a year after the S7. There are other reasons, but they tend to make the trolls restless. We'll skip them.

Ok I might be off by a year or 2 but I can say with 100% certainty that the note 9, 10, 10+ and flip3 don't have an unlock bootloader option.
I bought all 4 from Samsung all unlocked and not tied to any carrier. First boot with no sim I checked dev options and there was no option to unlock the bootloader. My note 9 might have had the option in the menu but it was grayed out and I couldn't find anyway to make it work.
A quick Google search for rooting the snapdragon version of any of these devices essentially says "NOPE".
The only way to root one is to buy a non US version. If it has a snapdragon soc you're out of luck.

You got where I said "I guess the disclaimer is misleading" right?

I didn't see that sentence in any of the posts but perhaps I just missed it.
It doesn't change anything either way. Anything is possible, even you somehow getting a device with this setting. That being said you also seem to be the only person ever to receive a USA device with said option.
It's hard to believe because it would mean the wrong firmware was installed (which makes no sense in itself) but with that firmware the device should have been a brick. The soc is completely different. It would be somewhat like trying to use Nvidia drivers on an AMD GPU... It just wouldn't work.
I dunno... I don't disbelieve you but I don't believe you either. It's just so far fetched for many reasons

Lucky? I dunno. Had I known it would cause this much trolling, I wouldn't have bothered to mention it.
I have a general question. I am unfamiliar with rooting/unlocking bootloader on Samsung devices. Is it possible to revert unlocking the bootloader and going back to stock traceless?

Partially. I just did that: I have AfWall running on my old phone, tried to unlock the Flip with this manual here in order to use the firewall there, did something wrong - and stumbled upon Netguard while searching what might have happened and decided to give it a try first. (Unless there is a custom ROM for the phone available, I have no other need for root or an unlocked bootloader.)
From what I could find on my Flip 3, you can unlock and relock the bootloader as you like - but as soon as you install a non-genuine bootloader (i.e. one chnaged by Magisk) you will trip Knox - and this cannot be reverted.
In such a case you can still re-lock your bootloader and unlock it later (on my phone, that "7-day-no-switch-indeveloper-options" routine kicked in, but you can circumvent that) - but Knox will stay in its state. From what I read this means some things will not work such as Samsung Pay, but I do not know the details (yet) apart from that it does not bother me ;-), and the nag screen during boot is gone.
Thanks for your reply. Kinda sucks. Never had problems with my former mobiles to get back totally to stock without traces. Guess I disregard rooting for now

Well, it's better than my Sony - there it is "once unlocked, always unlocked" with no way back at all
But I have to admit I understand the logic why the manufacturers do that, at least to the degree that they trip a fuse as Samsung does.
By rooting the phone, you shift the responsibility for the software state of the phone from the manufacturer to the user, so I think it is okay to implement something to make it clear to possible future buyers that it is or has been in that state.
(This does not include however all the other stones they put in the way of people wanting to develop or use custom ROMs!)
I remember I also had a Xperia Z3 compact.
Main reason for me for rooting, is the ability to use tools like tasker without non root restrictions or just trying customs roms without bloat, but usefull features. Guess u shouldn't have bought a Samsung lol.

Oh, trust me - as soon as I hear there is a custom ROM that works as a daily driver I will root mine as well. I really hope that there will be one for this phone

Sadly there is no Fairphone mini or Fairphone Flip - or would it be Fairfliphone? ... Flipfairphone?... - yet (if ever), so the only current alternative would be Motorola. And the price tag for the Razr is simply too much, even if I personally think it looks better than the Samsung. Additionally, I do not know if they are in any way better when it comes to rooting or loading custom ROMs.
