[GUIDE] Unlocking the Galaxys S5 Bootloader using DEV Bootloader [KK-MM]

[GeTex]

Alright then, unless you guys are going to dig around to see if there is a workaround, you might as well update OP to let AT&T users this isn't possible.

The Op was updated before you even made this comment

Are you always so hostile? Thanks for the work you put in but man, change your tampon.

Alright everybody. Let's try to show some empathy and respect. These are exciting times.

But seriously, read the entire thread before posting. Forums 101.

First contrary to popular belief, I am female

Second, when you waltz into a thread all "I'm not a noob, but i decided to run both methods twice" Everyone's gonna look at you stupid....

 

[ryanbg]

Someone wanna send me the ATT aboot? I'll pull the keys and check.

^ Hey @N4styN1ghtm4r3 Pull your aboot if you would be so kind for @ryanbg

I'm 100% sure it's just this command in terminal emulator

dd if=/dev/block/mmcblk0p6 of=/sdcard/aboot.mdn

correct me if it's wrong

You misunderstood me. I ran both methods, once each, but people were saying you have to run the commands twice, which is what I was stating I did.

Just making the kiddo some breakfast, then I'll get on it.

Has anyone else noticed you cant flash any firmware. I tried changing the modem and it will not flash. I pulled the plug and flashed PB1 full factory tar image and it flashed the system, boot and recovery images but it did not flash any bootloaders, firmware or modems. After full factory tar image flash in odin I still have an unlocked phone, which I should not. Do you have any input @beaups. Should this have relocked the bootloader.

I'm on OK3 too and tried flashing the PB1 modem using ODIN from the CM13 thread and it doesn't look like it took either.

Alright, here is the aboot.mdn.

Beaups has responded that there's a method to getting it to unprotect the partition to accept it. read back

Also @ryanbg, your aboot is here

You can't flash the bootchain of other devices. Only boot/recovery/system

Appears the key is different for ATT. That's really interesting since they never released a Developer Edition for ATT.

So i should take everything out except for boot.img, recovery.img, system.img.ext4? I dont really know what all the files are for, just trying to avoid brick.

So we're out of luck then?

I think so unfortunately, unless we come across what we need.

I advise against doing this. Just flash a custom rom. You can do this, but it might not work as expected.

Hypothetical question, if i'm on the OC4 bootloader(no OTA's since OC4) and running the PB1 firmware or just kernel and do the unlock method. Would you or anyone else know what the bootloader would be at? Just asking to give questionable ideas/thoughts to what JrKruse had posted. Just reading these posts day by day before i take the "plunge" for everything to "pan" out I'm currently running MOAR with OC4 firmware... Awesome Dev's with a community coming together..:good:

I'd assume the 'dev edition' firmware variant att s5s need is probably some factory firmware, or might not even exist, the check is just simply in there because it was never taken out. Either way, chances are looking slimmer and slimmer for att folks :/

Whatever bootloader you're on, it'll remain the same.

So guys I have twrp installed when it comes to custom roms now for Android M for the S5 are we limited to CM13 really or does anyone know if there is any Touchwiz based Android M roms mostly for my gear S otherwise guess I'll install CM13

 

[N4styN1ghtm4r3]

I feel a bit stupid for failing to mention this, but sometimes I forget, I'm on an AT&T s5 active. From my assumption, there isn't much of a difference though. Maybe someone with an original s5 should give it a shot, you have nothing to lose.

Thanks and sorry for the confusion.
