Hi Everyone;
I just purchased an AT&T Galaxy S5 SM-G900A Baseband G900AUCU4BOF3 without checking first of course whether it was rootable / upgradeable. After lots of searching there are plenty of older posts saying "no not possible" but are 1+ year(s) old. There are some newer posts saying this phone / base band IS upgradeable to Marshmallow (6.0) but no confirmation it's worked with this version.
The end story here is I am stuck with it, but would like it to upgrade to Marshmallow (Stock AT&T Firmware is fine, root at this point is on the wishlist). It is carrier unlocked and works at the moment.
Can anyone with this specific phone help me? I am familiar flashing with ODIN, Installing recovery, etc. Not worried about voiding warranty, tripping warranty flags, etc.

I've just purchased a new S6 with the same model number as the T-Mobile version but it's unlocked and unbranded. Does anyone else have this phone and when do you think it may get marshmallow?

You will get the update anyday now. It would be awsome if you could get a system dump for that firmware youre running. we could reallydo some development witg that and be able to get marshmallow along with you.
I have the same phone, also purchased unlocked though Best Buy. Will we be getting a separate software update from T-Mobile? Once released, how can I get that system dump? I can see how it would be usefull for development. Haven't rooted because I don't want to trip knox and loose warranty. Impatiently waiting on the update. Didn't know if I had to wait for the T-Mobile update to roll out first.
To my knowledge our phone is just a different CSC under the G920T variant... For G920F, which is the international version, mostly European, different CSCs mean different regions and/or carriers. Likewise, for G920T, there are two CSCs: TMO (which is T-Mobile) and XAR (which is our bloatware-free version). That said, if the TMO firmware comes out first, we'll be able to flash it manually with Odin but we'll not receive OTA. The downside is that we'll have to bear with the bloatware until we flash back to the XAR Marshmallow after it's released. As for Knox, as long as we're flashing official stock firmwares from Samsung Knox won't be tripped.
Hello there, I am from the UK, and got myself a s5 (which i didnt realise was the at&t version til i looked into rooting etc) but just need a few questions answered
As I realise, that the phone has a locked bootloader...... and the recovery is safestrap....and my phone is running 5.0 BOF3
Any way I can.......?
Root or downgrade....?
Debrand it of AT&T stuff
Debloat it, as in the UK, the AT&T stuff is useless!
I only want to root it to use adaway and titanium backup, although non root, I can use adguard.
Any answers to my question greatly appreciated!
OC3 was the last AT&T firmware that could be rooted/downgraded. I have an S5 Active with OJ3 and can't even update to Marshmallow because I'm on Cricket and not AT&T (even though Cricket is owned by AT&T and operates on their network).
I've been gifted an AT&T S6 (build and Android version as noted in the Subject), and after some soft bricking adventures with Odin followed by more cautious Googling and re-flashing stock firmware, it appears to me that there's no way to root this thing.
Is that correct? There is no way to root a MMB29K.G920AUCS5DPJ1 device once it's in that state natively? No downgrading to an earlier version, no clever ways to get to recovery and flash SuperSU, do not pass Go, do not collect $200?
Hey All -
As a newbie I'd like to get some clarity as it's a little unclear to me still....I almost purchased a Note 8 from my carrier (AT&T) and
prefer to remove all the bloat so I wanted to get more details before finalizing my purchase. So the phone would be a Snapdragon CPU and carrier locked - which isn't a big deal for me. My goal would be to install pure Samsung firmware and be able to receive updates from Samsung without waiting for the carrier and remove the bloat.
Btw, I did a forum search and found something close but it was a Verizon related topic.
So my questions:
1) Is this possible without tripping knox?
2) What is lost between stock firmware and carrier firmware other than bloat? I'm assuming all the bands and network features keep working as before.
I'm also assuming since the IMEI number is an ATT branded phone Wi-Fi Calling and VoLTE is not lost or is CSC uploading still required with stock firmware?
Thanks!

There isn't much bloat on them anymore these days. Yes, anything you do will prompt Knox. You can disable almost any app now without rooting the phone, so no root is needed at all for that purpose. Just disable it in settings, or if not allowed on a specific app to do that, just install "BK Disabler" from the play store.

I've flashed the stock rom through Odin and fairly certain it didn't trip Knox or any issues that aspect since my company verifies Knox compliance.
With the stock rom I get my hotspot through AT&T which I couldn't on the AT&T rom, I just used the tutorial on here to flash it with no problems. I will get the updates for the U1 when it gets pushed down and have got security updates just fine. You can disable a lot of apps already though on AT&T stock
Oh and you don't lose anything other than the AT&T pre installed garbage that nobody really uses
**edit just checked and yes I'm 0x0 on Knox so it didn't trip it

Yes you absolutely can install the unlocked 950U1 firmware on your ATT device. All the 950U devices are identical and the firmware is 100% interchangeable and will NOT trip KNOX. I'm running for T-Mobile firmware on a Verizon Note8 right now. KNOX is only tripped when you flash unofficial firmware, such as custom recovery and ROM.
There's really not much of a reason to do it though. Theres very little bloat on these, and you will lose VoLTE and WiFi calling by flashing the unlocked firmware.
But if you still want to flash the unlocked firmware, follow this post:

Did you guys who flashed stock firmware get stuck with the 80% battery issue? Cause I thought about it just to get Oreo early but I don't want to lose 20% of my battery. Also have any of you tried to flash a regular update to a carrier note 8 using the update from SD card option?

You only lose battery capacity if your root a snapdragon. Not just by flashing official firmwares.

Okay I was confused. Thanks for clearing that up for me. I hope they find a fix for that eventually.
Don't hold your breath!
Hello,
I have some noob questions to ask before trying this out on my G920T (Baseband version: G920TUVS6FRC1 - which is running Android 7.0). Here's a little bit of background about my situation, I was with Tmobile Prepaid up until the end of December 2019. I ended up getting my phone unlocked by Tmobile and transferred my number to an AT&T Prepaid account.
I was looking to try and get HD Voice/wifi calling working on my unlocked G920T. My question is, when flashing different carrier firmwares, does it matter what the storage capacity of the phone is? Would I be able to flash G920A firmware (no matter if it came from a 32GB Samsung S6, or 128GB (not sure if AT&T ever had a 128GB version of this phone)?
Also I read that it is better to use the princecomsy (my apologies if I messed up on the name) version of Odin rather than the non-cracked versions. Is that correct?
Would I be able to flash different carrier firmwares regardless if my bootloader is locked?
Thank you to anyone that can help.
