Hi,
I am using samsung Galaxy S6 ATT version with the following software version:
Android Version 6.0.1
Android Security Patch September 1,2016
Baseband Version G920AUCS5DPI1
Build number MMB29K.G920AUCS5DPI1
The phone is sim unlocked but I need help with rooting / unlocking the bootloader. On checking this forum I did not see that there is any way to do this on my version. So I was just wondering if there is anything else (such as installing any other ROM) that I can do with this phone.
Since the contract on my phone has expired I tried using this phone with another carrier and it does not seem to be working (tried with metroPCS) the phone does not show any other network operators except ATT/T-mobile and Verizon and on trying to connect to T-mobile it fails to connect (metro PCS uses T-mobile line)
After spending few hours with an account rep from metro he felt the phone may not be compatible. So at this point I am just trying to figure out if there is anything I can do with this device.
Sorry for the long winded post but I just hate how these carriers tell you that after the contract you own the device but their own software updates mess up any chance of using your own device as you want.
Appreciate any insight or links to help me figure out if anything can be down to get rid of the ATT rom.
Thanks,
Matt

Last time When I went to USA for business trip, I Bought ATT G2 (D800) model.
Now i'm living on South korea.
Currently my ATT G2 have v20c version and I want to upgrade for v20y without rooting.
Because all of korean Banking and credit card app run threaten scan and if rooting related files found on phone, it won't run by security problem.
But, When I tried software update every time, it just loop "Not yet registered" popup occur and I won't 20y update from ATT FOTA server.
And I also doesn't have ATT or ATT Go phone sim. If I get or borrow ATT SIM and connect on Wifi, Can I get a 20y OTA from oeversea?
Exactly, Am i need a ATT SIM or Go Phone SIM for successfully get a OTA file ? also that ATT sim must be activated on ATT account ?
I think some of my colleagues have a deactivated ATT go phone sim. But i'm worry that this deactivated sim also can get a OTA from ATT FOTA server.
I need a brothers opinion or success story who can success got a OTA from oversea and not ATT(like T-mobile or H2o or Straghit talk... ) environment.
I also got the same problem with you. Hope someone will help us

I did. Worked fine. I needed the files which i couldnt find on the internet but managed to dig in deep and after a month or so , found them.
Ok, so my question ha a few points here. I have been flashing roms for many years but never really though of this until recently as I now have an unlocked phone.
1. As my Sprint Note 5 is unlocked, can I flash say the Unlocked Version of software to the phone taking away carrier branding? I manage a store from another carrier and I hate that when I boot my phone it shows Sprint. I know it will not trip knox as long as it is Official Stock software.
2. If I do flash said Unlocked version software replacing Sprint software, will it change my connection at all? I have seen that flashing ATT software on a Verizon device did manage to improve ATT tower connection however I wonder if this is maybe a placebo effect as opposed to actually changing the bands and connections the device makes.
If you guys could help me out that would be great. :good:
Cheers
There is no unbranded firmware for the Sprint model because well, it is a exclusive model so even if you flash XAS instead of SPR firmware some or all apps will still appear. The only way to get rid of everything Sprint is via custom ROM= tripped KNOX. The SM-N920P cannot run another firmware.
Hi,
I recently brought over my SM-G920A from ATT to T-mobile. I cannot get the ATT phone to recognize the existence of the Signal Booster--which works great on T-Moble phones--so I cannot connect to it. I have been a few rounds with others here that have walked me through the attempt to flash this phone with T-Mobile baseband load and it simply will not work. The phone is unlocked and is using the following load:
baseband G920AUCS7ERC1
BUILD NRD90M G920AUCS7ERC1
I have dev mode unlocked and have no idea what to set those settings at or what they were originally, I attempted to flash SM-GO-G920T onto it but it will not take because there is no current bootloader that can overwrite the ATT version.
So, I'm about to go back and flash the old software back on here.
But, I would really like to see if anyone has any ideas that can help me either get this phone to recognize the T-Mobile 4G-LTE signal booster or help me figure out how to get this phone to accept the SM-G920A load all together.
I would like to thank everyone in advance for your time. Please help.
Thanks and have a great day!
Hi there, new member with a first question.
I bought an S10+ (SM-G975U) online, unlocked, to be used mainly with AT&T when in US, and different carriers when traveling. IMEA check shows the phone was originally on Verizon carrier, but works fine with AT&T sim card. However, it's not receiving OTA software updates, and the security patches are way behind. When I try to force software updates, says it's already up to date. Seems like on unlocked phones, or switched carriers the updates don't happen. I tried booting the phone with a working Verizon sim card, still no updates. Online searches say that flashing the firmware is my best (or only) option. I downloaded Odin, but I still have a lot to learn and don't want to brick my phone. I'm not sure which firmware version to get. AT&T vs Verizon? U or U1 since it's unlocked? Do I flash all 5 files or just some of them?
Thanks.
Hello everyone, I've been looking for some information about this Galaxy a51 (which I think it's a US version and I'm outside US) with the following features:
Model number: SM-S515DL
Android Version: 11
One UI version: 3.1
Baseband version: S515DLUDU8CUK1
Kernel version: 4.14.113-22754548
Service provider software version: SAOMC_SM-S515DL_TFN_TFV_RR_0015 TFV/TFV/TFN
Software update info version: S515DLUDU8CUK1 / S515DLTFN8CUK1 / S515DLUDU8CUK1
Security patch level: October 1, 2021
I got it from Amazon and it says it's a CDMA device, of course it is network locked and it's showing the invalid SIM card message. So I got a couple of questions hoping you can share your comments:
1. Is it possible to do a stock firmware flash and get rid of carrier content and locked SIM?
2. Can I use galaxy firmware.com files to do so? I see there is a S515DLUDU8CUK1 version with different region, if so which region to pick?
3. or maybe is it possible to do it by installing a custom ROM?
4. Could the z3x or octoplus unlock network? (I can't get the unlocking PIN or region screen)
There are still a lot of things to learn, unfortunately I saw there is not much info for this model on forum sections. I found mostly information for A515F and other variants of a51, could I just use them? is there any risk? Beyond the unlocking network I'd really like to try a custom rom and get rid of all the stuff it comes with.
Greetings!
Yeah, eveything should be possible, but you must change you language manually after setup, when you flash a different Firmware from another country or another region. If you flash a new Firmware you also should be able to unlock your bootloader and then you habe the Go for flashing every Rom you want. With a different Rom or Firmware you should be able to get rid of Carrier content etc.
Okay so far I've been using it as an offline device and it is just fine. I am waiting for SamKey to release the network unlock since it only supports binary 3 and below. I dunno which other software supports binary 8. My bootloader is locked it does not show up at developer options.
Anyway I am just playing games on it, watching videos and surfing the net with wifi. Just like they say if it's not broken don't fix it. I will just wait until this device gets more support and then I'd probably try roms and other stuff.

Not sure if it will get much support being from 2019. I'm not an expert with Androids but bought same models from Tracfone and with 60 days after activation they were eligible for unlock. They took IMEIs and sent email with two codes in it (different based on IMEI because for two of my devices they were different). after punching number it brought up the device unlock menu and after the two codes were entered got messages that they're unlocked. worked with different sim without an issue afterwards. Its currently up to Android 12 UI 4.1 as far as official updates.

Could you give me a hand for the release, to which email address did you send the imei for the unlock ?
