[Q] Accessing Bootloader - Verizon Samsung Galaxy S6

Hey everyone! I'm new to the XDA forums, and I just purchased my Verizon Samsung Galaxy S6 about a month ago. I thankfully just successfully rooted it using PingPong Root yesterday. But I was curious if anyone knew how to access the bootloader to find out if I can flash custom Roms and all that. I didn't need to unlock the bootloader to root it. But I don't want to brick my phone trying to flash anything. I tried to do the -power off- -up- and all that to get bootloader, but all I was able to get was the stock recovery and some sort of thing g that looked slightly like a bootloader, but allowed me to reboot, factory reset, and reboot I'm debug mode.
Someone please help!!! I don't know if this is the right place I'm the forums, so please don't delete this post, if I did anything wrong. Thanks everyone.
I also forgot to mentiom, when I boot my phone up, it has an unlock symbol and says Custom underneath it. Could that by chance mean that the bootloader is unlocked aswell? Opinions? Suggestions? All help would be appreciated

VZW bootloader is locked. Doubtful that will change.

There isn't a way around that even if my device is rooted, without getting the Dev edition?

Do I have to have the bootloader unlocked to flash custom ROMS and any thing other than stock stuff, such as a recovery, etc?

No recovery as long as we have locked bootloader. You can flash roms using flashfire.

This may be a noob question, but what exactly is the use of a ROM and what would be the best ROM to flash? Will it erase everything on my phone, doing so? Contacts, Apps, etc? Where can I find flashfire? I already have flashify from Google play store.

Not flashify, you need flashfire by chainfire do a search on Xda for it. As for roms we don't have alot to choose from but go to the Android Development sub forum and take a look. Most the roms have significant better battery life because they are debloated etc.

[Q] Rooting Nexus S without unlocking bootloader

I've seen many different rooting methods for the nexus s but unfortunately they don't allow rooting without unlocking the bootloader like the samsung vibrant allows is there anyway I can root my phone without unlocking the bootloader?
why I don't want to unloack the boot loader because I'm fine with the stock ROM on my nexus s. I was really into installing ROMs and things with my Vibrant but the Nexus S feels really complete so I feel like I don't need to unlock my boot loader
Also for the first time I have decent signal in my house after switiching from my blackberry to android so I don't wanna change my baseband and my battery life is good too so I don't want to mess with the kernel
Really? You posted in the same incorrect forum twice with the same question cut and pasted. Nice work!

You know you can re-lock the bootloader with a fastboot command, right? And the little open lock goes away.
i'm sorry i accidentally reposted i pmed the moderator right away because i didn't know how to delete the post and this is the right section its a question...
i just have one question i can relock right but if i do unlock the bootloader will it change my kernel or baseband settings? i really couldn't care about the warranty and such
it's like opening the door....if you do nothing inside, nothing will happen
yes i get that but i can't flash back to the original recovery as of now and so no changes to the kernel and baseband alright thanks!!
also is there some sort of a "ODIN" availabale for nexus s because thats what I used to always flash my samsung vibrant back to stock. will OTA updates be affected if I root and unlock the bootloader?

Yes you can use Odin with Nexus S, but consider it the last resort because normally you can do everything via adb and fastboot -- that's the advantage of having a Google phone.
For OTA updates, I'm pretty sure it will not work because OTA update requires stock recovery but rooting requires you to flash a custom recovery.

Locked out by Verizon after cm10 flash

thanky you to anyone ahead of time for reading this post. I really could use some help.
I have a Verizon galaxy s3 which I rooted 3 weeks ago when i got it. I know it was rooted as i had super user permissions, and deleted many bloatware apps. I waited until cm10 came out to flash a new rom and after doing so last night my phone now boots up with this message "System software not authorized by verizon wireless has been found on your phone. Please turn off your phone and go to the nearest Verizon Wireless store for help."
So I tried to boot it in to recovery mode but when I did, the same message came up, only this time it said "recovery booting" in small blue writing in the top left corner.
I followed the directions to a T from a page entitled "Jelly Bean for Verizon Galaxy S3: Unofficial CyanogenMod 10 (CM10) Nightlies Available for Flashing!
From what I understand, the bootloader was somehow never unlocked by kexec. because I cant get in to recovery mode, I was wondering if there was a way to disable the bootlock by installing kexec via odin.
Also, whether it was a good idea or not, I re flashed the stock rom via oden last, which was successful but, nothing has changed still the same response all boot ups. Download boot obviously works though as I have been able to mess with it in odin.
any insight on this would be graciously appreciated.

Okay, first, If you did follow the directions for that thread, i'm sure it would of worked, I'm pretty sure you are missing something here and i'm pretty sure from reading your post that I think you didn't unlock your bootloader. kexec was a workaround for the locked bootloader, it doesn't unlock it. I would follow droidstyle's guide to unlocking the bootloader, http://forum.xda-developers.com/showpost.php?p=28530409&postcount=2 after you unlocked it, i'm pretty sure you forgot that step. But the issue when flashing back to stock via odin and still showing up its a custom rom, I don't know why that would happen but I suggest reading section 2 of droidstyle's guide on flashing back to stock. http://forum.xda-developers.com/showpost.php?p=28530394&postcount=1
So first, I suggest to return to stock, then root, then unlock bootloader, and then install the rom of your choice, preferably without kexec, if you don't want the triple reboot.

Like he says above you have not unlocked your bootloader . Restore nandroid or recover to stock. Then unlock your bootloader and try again

Get rid of the Verizon screen of death
I got the same error msg after flashing a nightly of d2hacker's unofficial cm10, after I had flashed a few nightly's before of the same ROM w/ no problems. I had to
1. Flash a stock bloated unrooted ROM via odin (lemme know if you need a link to one)
2.boot into droid recovery and do a factory reset, and wipe the cache partition also.
If you don't do step 2 you end up w/ a permanent verizon 4G LTE rainbow boot screen :silly:
I haven't re-rooted yet but I'll be trying the official cm10 now that it's up.

Incorrect. It actually means the opposite. The only way to tell if your bootloader is unlocked is to flash a custom rom/kernel and boot up. Please people, do some reading before you turn your phone into a paperweight. That unlocked lock/custom means you're running or were running custom software and it's been detected as such. One possible culprit is your "custom" recovery. If your bootloader is unlocked, you will not have that problem.

I think it has to do with the "degree" of customization. IE a custom ROM or Kernel will get you the verizon screen of death for sure if you're not unlocked. The custom/unlock icon seems more for minor things like a custom recovery, possibly different firmware or tweaking specific settings.

Could he Odin back to stock through download mode though? Or will the locked bootloader block download mode and recovery mode too when it detects tampering?

The secure aboot.img only checks 3 of the 5 system images on boot. Since we can flash a custom recovery to the recovery partition, the secure aboot img lets it ride, but knows it there....hence why you see the custom lock screen, but device still boots. Kexec allowed the bootloader aka secure aboot.img to see the stock kernel(boot.img) and pass signature checks, then side loads the custom kernel. Thats why there was 3 reboots...now that the bootloader is unlocked, we ditch kexec because unsecure aboot is unlocked and not checking signatures.
However, if you flash a kernel thats non kexec and the bootloader is locked, you will get the verizon screen of death since the secure aboot.img is checking signatures. So never lock the bootloader unless your on stock rom/kernel or using kexec.

Jesus. All of these people who don't read up on things before they flash something astounds me.

Well, step 1 is going Odin back to stock, but if a cache wipe and factory reset aren't done (like in Droidstyle's guide), then it will never completely boot, at least that's what I experienced after my phone sat at that screen for 10+ minutes. It doesn't run the user setup again.

HELP! Custom under Samsung boot logo

I need to return my phone and ive used the guide to reset my flash counter with triangle away (which was never tripped, just did it for piece of mind), then i used odin and used the stock kernel and stock image to reinstall back to stock. Everything passed but when i boot my phone up right under the samsung logo it still says custom with the unlock logo. How do i get rid of this so i can return my phone back to verizon?

that means your bootloader is indeed locked...look around on the forums a bit! When the custom unlock screen is gone then your unlocked. I believe there is a guide in the dev section that explains this. :angel:

Your out of luck. Locked bootloader means no way to return to a previous version on Android. Even if its not being used as a phone it's basically stuck there. There are jtag services out there to revert back to 4.1.2 but I've heard a lot of mixed thoughts on those

Moved to Q&A.
If you decide not to go the jtag route you could:
1) install SafeStrap
2) flash SuperliteROM into stock slot
3) flash XPosed and the modules that would make SLR look and act as you like.
This is what I have done with the i535 I picked up that was on NE1.
