[Q] Why does Locked Bootloader Matter? - AT&T Samsung Galaxy S 5

So I have the AT&T S5 with a locked bootloader. I rooted it, put safestrap on it, and installed a custom ROM. Now I read that the Tmobile S5 has an unlocked bootloader, but given that I can root and install custom ROMs, why is the Tmobile variant any better? Also I read locked and encrypted used interchangeably regarding the bootloader, perhaps they are both locked but not encrypted?
Lastly, does an unlocked Tmobile S5 work seamlessly on the AT&T network, it appears the LTE bands overlap so I'm guessing so. Is there a good reason to sell the AT&T variant and get the Tmobile one?
Ungh, stupid AT&T.

You can only flash custom roms based on the stock kernel. With a locked bootloader you'll never be able to flash an aosp rom.

Nor will we be able to flash 4.4.4(or later) when it becomes available. We are stuck waiting for att to release an update, and then we might lose root.

Does this mean that the custom roms that are installed are still ultimately based on the original G900A one, or at least the kernel is the same?

Basically, yes.

The recent OTA will update the kernel and firmware, right? But does towelroot still work? Is it likely that the bootloader will be more difficult to break later if I do update?

[Q] Can I install this ROM with locked bootloader?

Hello,
Am I able to install ROMs that are stock based if I do not have unlocked bootloader?
I am specifically talking about this ROM: http://forum.xda-developers.com/showthread.php?t=2180208
Thanks!
I don't think so,maybe later the dev will release a version for locked bootloader.

Okay thanks for the quick answer.
I just got confused because I checked this thread about ROMs
http://forum.xda-developers.com/showthread.php?t=2171958
And on the first 3 it specifically mentioned [Unlocked Bootloader] and the 4th did not say that, so I figured I might be lucky^^
Since there isn't a CWM recovery for locked bootloaders yet there is no way to flash ROMs with a locked bootloader. Once there is it will just be a case of flashing the ROM and then the stock Sony kernel.

[Q] What ROMs can I use with a locked bootloader (I have a C6606)?

I've been searching around, but can't seem to find a straight answer on all ROM's. Which ROM's are usable with a locked boot loader? Thanks in advance.
Edit - Done some more reading... Can I do anything with a locked boot-loader really? Or am I forever limited to 4.1.2 based ROMs?
Take a proper look in the Android development forum dude!
There are loads of ROMs you can flash on a locked bootloader. Generally the ROM will say LB/UB and must be a modified stock ROM.
The only ROMs you can't flash are cyanogenmod/Aokp /aosp based ROMs.
Or upgrade to 4.2.2. with a stock tft via flash tool.

Thanks so much, sorry im new to sony bootloaders. So if I upgrade to 4.2.2 I can flash cyanogenmod/aosp Roms? I really want to use parandroid... Or is that impossible as of currently? Also, will the boot loader eventually get unlocked? I'll probably end up returning this phone if its not possible for a long time. Again thanks.

Do not flash paranoid on your phone with a locked bootloader , you will brick your phone.

Alright I see. Thanks. Hopefully there will be an unofficial bootloader unlock for this phone eventually.

Custom Kernels?

Hey all,
I have searched and didn't find any obvious thread that discussed kernels for our device. I'm on the stock rooted 4.4.2 leak. Are there any kernels out there that might work for our device?
Sent from my SAMSUNG-SM-N900A using XDA Free mobile app
No. The bootloader is locked on this phone so you cannot use custom kernels or AOSP ROMs. You're stuck with the stock kernel until the bootloader is unlocked, which will never happen.

[Q] Stock rom without AT&T bloat without root?

Are there stock roms available to flash that don't include any AT&T bloat and if possible, also the other Motorola apps?
If you want to flash a custom ROM or downgrade from stock JB to ICS, you'll need an unlocked bootloader.
Have you tried Holoblur?
There's always the trusty ole Mexico Retail ROM

Just got my s6 now to root it!

Okay so about 3 hours ago I got my galaxy s6 and no I wish to root it although I'm out of the loop on what's going can someone clarify for me?. I keep seeing that root isn't supported on 5.1.1 luckily for me I'm still on 5.0.2, I tried ping pong root but that didn't work so now I'm thinking of using cf autoroot. I keep seeing people saying that after root they can't hear when making a call or that data is not working I'm just wondering what's going on? I just want to get updated

The people having the issues with call volume and fingerprint scanner are using the eng sboot for 5.1.1
Cf-autoroot or pingpong for 5.0.2 will both give you root with no issues :thumbup:

It was a leaked engineering bootloader. Yeah, if you're gonna do a custom rom, I would flash something that matches your bootloader. (5.0.2 rom for a 5.0.2 bootloader, etc)

ROOT is supported on 5.1.1 when you flash the custom kernel called UniKernel http://forum.xda-developers.com/gal...d-development/kernel-stockmod-kernel-t3100395 and TWRP is also available for people running 5.1.1 only version 2.8.7.1 though but still don't update because most ROMS are based on 5.1.1 and you cant flash a ROM that is based on 5.0.2 right now.

Hmm so I can't flash 5.0.2 roms right now? That's weird because last night I flashed twrp via Odin and then flashed the super su zip then flashed looper rom and that's 5.0.2 and it's been pretty great so far

Yes but do you have the 5.1.1 bootloader? If so you can only flash 5.1.1 ROMS.
Why doesn't it work on of6?
