[AT&T Samsung Galaxy S 5] jstinger9489:
Attempt to speak to Samsung Technical support about the bootloader.

I know a little about android. If I made an idiot of myself in the following transcription, please tell me. I can only get better with constructive criticism.

Chat InformationPlease wait for a Samsung Agent to respond.

Chat InformationYou are now chatting with 'Marlin'. There will be a brief survey at the end of our chat to share feedback on my performance today.

Chat InformationYour Issue ID for this chat is LTK112560814739X

Marlin: Hi, thank you for contacting Samsung Technical Support. How may I help you today?

Visitor: I apologize for the system saying I have a Galaxy S3 on the AT&T Network. There was not an option for the Galaxy S5 SM-G900A.

Visitor: I am looking for a way to unlock the bootloader that shipped with my phone.

Visitor: Baseband= G900AUCU1ANCE

Visitor: Kernel Vers.= 3.4.0-964333

Marlin: I understand that you want to unlock the bootloader on the device. Correct?

Visitor: Yes.

Marlin: Thank you for confirming.

Visitor: Can you send me an unlocked bootloader version that I can flash via Kies?

Visitor: I am aware that unlocking the bootloader would nullify my warranty, and I am willing to give that up for the opportunity to develop for this amazing piece of technology.

Marlin: I am afraid there is no option to unlock the bootloader from our end as it is considered rooting the device.

Marlin: Samsung does not recommend rooting the device as it affects the device performance and voids the warranty.

Visitor: Unlocking the bootloader does not give the device root rights. I am not worried about the warranty as if anything were to happen to the device, I am technologically savvy enough to replace the hardware myself.

Marlin: Unfortunately, there is no unlocked version of bootloader from Samsung that can be flashed via kies.

Visitor: Root is achieved by giving Root access to programs and giving the linux kernel certain commands. I am not looking for root. I am looking for an unlocked bootloader so I can make a backup of my phone as it is. Can the T-Mobile bootloader be flashed into the AT&T hardware?

Visitor: Is there any unlocked version of the bootloader that can be flashed via ADB or hard installed through the original recovery?

Marlin: I am sorry; there is no option to unlock the bootloaders on Samsung phones.

Visitor: Tmobile S5 SM-G900T has an unlocked bootloader.

Marlin: I should inform that only few device are released with the unlocked bootloader.

Marlin: Yes, the unlocked bootloader version can be purchased separately. The locked bootloaders phones cannot be unlocked.

Marlin: T-mobile bootloader cannot be flashed on ATT hardware.

Visitor: Sooo.... You're saying that the $800 that I paid of my hard earned money for a device that is now MINE, is not useable in the way I wish to use it?

Visitor: What are the differences between the AT&T Bootloader and the T-Mobile Bootloader?

Marlin: I will provide the information.

Marlin: May I place you on hold for 3 minutes, while I gather the information on your request?

Visitor: Sure.

Marlin: Thank you.

Marlin: Thank you for holding.

Marlin: I have checked the information.

Visitor: Okay.

Marlin: I should inform that there is no big difference between the T-mobile and ATT bootloaders. The AT&T bootloader is highly encrypted compared to the T-mobile bootloader.

Visitor: Why then would the T-Mobile bootloader not work with the AT&T hardware?

Marlin: As the AT&T version is encrypted it may not be broken. Unfortunately, all Samsung devices comes with locked bootloaders as carriers insist its for users protection and their network integrity.

Marlin: I regret the inconvenience caused to you.

Marlin: I would surely provide if there was any information on unlocking the bootloader on our end.

Visitor: I understand that the AT&T bootloader is encrypted. If that is the only difference between AT&T and T-Mobile's bootloaders, why then can I not install the T-Mobile Bootloader onto the AT&T hardware?

Marlin: I'm sorry for the delay. I'll be right with you.

Visitor: No Problem...

Marlin: I am sorry; We cannot estimate the reason as there is no detailed information on unlocking the bootloader.

Visitor: Can you give me a link where I can download both the AT&T Bootloader and the T-Mobile Bootloader so I can attempt to install it on my AT&T S5?

Marlin: I wish I could provide you with the link if available on our end.

Marlin: Samsung does not provide bootloaders separately as it provides only update links that are available via kies.

Marlin: Not to rush you, are we still connected on the chat?

Visitor: Can you provide the ROM signature for the AT&T 4.4.2 KitKat ROM so I can update the Open Source Programming as it was meant to be updated by the end users via the AOSP?

Visitor: Android Open Source Project agreement.

Marlin: I will be right with you.

Marlin: I apologize; As this is a technical chat support for the devices, there will be information only on troubleshooting the devices and its pre-installed apps. Unfortunately, there is no information on the device ROM signature.

Visitor: Where can I get the information I am looking for?

Marlin: You can contact our voice team and check with options on ROM signature and bootloader unlock information.

Marlin: I will provide the contact information.

Marlin: You can contact our voice support at 1-888-987-4357, Mon-Fri: 7 AM - 9 PM (CST), Sat: 9 AM - 6 PM (CST).

Visitor: Thank you.
