Bootloader - G2 Q&A, Help & Troubleshooting

For the life of me I thought you could only install stock modified Roms until the boot loader was unlocked then you could install custom roms. But I see people installing custom Roms and the bootloader is still locked or am I missing something. Confused

Loki is what is used to help you root and basically let you bypass the boot loader so you can install the custom ROMS. It is probably a bit more technical than that but that is what it does in simple terms. You use this until the bootloader is actually unlocked.
I'm sure someone can chime in and give you a more technical answer. Research it.

Are you on TMo? Be patient. It will probably come. It is still early in the game.

Can somebody tell me about this locked MF3 issue?

I just bought a galaxy s 4 off craigslist and its on the MF3 baseband. Does this stop me from flashing ROMs? What do I need to do to fix this?

I was actually just reading that over, but I'm still a tad confused about what ROM this is on. I have a splash screen when I boot that says "samsung" but below it says "custom" with an unlocked lock, and the rom is JDQ39.I337UCUAMF3, which makes me think that dude unlocked the bootloader and flashed a custom (leaked?) version of MF3. Still searching around to find if thats actually the case of not

[Q] root for latest android 4.3 update?

I recently received the ota 4.3 update for my at&t gs4, but I've been dying to try cyanogen mod on my phone or at least be able to remove a little bloatware. Could anyone point me to a tutorial somewhere to root this thing if it's possible yet? I do have a little experience with flashing roms and rooting with my old samsung replenish, but only with odin... thanks.
-EDIT Also is kingo really malware like many people on xda say? And does kingo work with the new MJ9 build for AT&T's S4?
If you have a little experience flashing Roms than you'll be experienced in the art of Google search. There are many threads about this already

Works the same for att even though its for verizon. Same root method but beware it could add malicious stuff to your phone and computer. Do a little researching first before you do anything. Good luck

And even when your rooted there is still no custom recovery for 4.3...so no rom flashes are possible

Thanks for the link to the tutorial. I've been looking stuff up about vroot and apparently it contains some sort of trojan... I also read a comment on YouTube where someone with the at&t MJ9 build had success with it but what are the risks other than bricking?

[Q] Does the new root method mean new unlocked bootloader methods?

Does the new root method mean new unlocked bootloader methods? or is the bootloader itself the problem and not root?
Thank you for your patience and answering me.

Like Avi said, two totally different things. There was an update in May and it also blocked root and the unlock method. They were able to gain root again, but the BL is much more involved.

You can install SafeStrap and install another stock ROM on slot 1. Then, you can use Xposed to add all kinds of customization and you can flash a mod that allows init.d to allow you install init.d tweaks. Doing all of this on your safe slot will keep you from messing up your stock slot. If you get everything set up in slot 1 and it runs well, there is a way to restore it on your stock side, but I won't go into that now.

Maybe you don't have enough space on your internal memory. When you go to create a rom slot, check how much space is required and how much is available

Bootloader Exploit Discovered YAY

My man Adam Outler strikes again... here YAYAY

Secureboot = NONE

You do know that "secureboot" has nothing to do with unlocking the bootloader. Even the old s3 had secureboot enabled and still let you flash recovery.
http://forum.xda-developers.com/showthread.php?t=2494037
Samsung’s secure boot feature only allows kernels with the company’s RSA-2048 digital signature to boot the device. So this just means we might be able to flash a kernel & if lucky a recovery but the bootloader is still locked.

I realize and know that. But there has to be some importance to it right? Like allowing to downgrade bootloader or something.
It means we could flash kernels & recovery. But the bootloader is still technically locked. Still, very good progress being made.

Nothing ever stoppled you from flashing kernels, it stopped your from booting them, and it still does.
This bootloader was not exploited, and not unlocked.
Closing thread because I am tired of this drama.
Also, Adam posted someone else's picture, not his work and not his device.

is the g2 bootloader unlocked?

I want to switch from the s4. the main thing killing development there is the damn locked bootloader. does the g2 have the same problem or are all otas unlockable? (this would be for Verizon)

I can't speak for all variants of the G2, but as a Verizon user I can confirm that the bootloader is locked. With that said, there is an exploit to get around this. Check out the development section for more info.

ours is technically locked, but due to a workaround (that I don't really understand) it might as well not be. we flash roms, mods, radios, and kernals all with very few problems.

yes it is locked on every variant (bar sprint). But that does not matter for ROM's and recovery, as they are lokified. :victory:
