[Q] Will the locked bootloader prevent me from flashing T-Mobile Stock ROM?

I don't know if other people have asked this question, but I read a lot about locked bootloaders (and yes, I've been there with my own phone xD) and they talk about how it's not really possible (?) to flash custom ROMs with phones like that.
I have an unlocked SM-G900A and I'm on T-Mobile, but I really need the Wifi Calling.
Will the bootloader think it's a non-verified custom rom?
I don't want to send my phone to Samsung again...lol
Thanks!

You should be fine, i'm running a tmo rom currently, not sure if WiFi calling would work though.

Also, before I start flashing, if anyone knows about Sammobile firmwares- do they have modems inside the .md5?
I have it ready but I don't really...uh...want to flash the modem if it's there. LOL so confused...I saw another forum where it said the modem was already inside the sammobile firmware file, but some say it's fine so...I honestly don't know... xD

Oh i didnt know you meant using odin for a rom, no i would avoid that, as for just normal g900t roms from the tmo section, yes you can do that with flashfire/safestrap/multisystem, i dont know about odin though, pretty sure it wont work.

You can test the following if you would like try to run the latest T-Mobile OB1_5.0 Firmware as a virtual system (you must start the following process from rooted OC4):
Part-1: Install MultiSystem
1. Download the latest Multisystem.apk and Multisystem.zip.
2. Follow the Instructions to install MultiSystem.
Part-2: Install T-Mobile_OB1 5.0 Virtual System
1. Download the system_t-mobile_ob1.img.rar, extract the .img and place it onto your device (use either internal or external sdcard).
2. Use ES File Explorer (with root access enabled) to copy the system_t-mobile_ob1.img to the following folder: MultiSystem/img/system
3. From the MultiSystem app enable "Virtual System," Press "Update Configuration," then select the system_t-mobile_ob1.img under "Primary System IMG."
4. Press "Update Configuration" once again and reboot.
5. Once the Green led appears during reboot Press "Volume-Up" for about 2 seconds.
Your device should boot into the T-Mobile 5.0 Stock, Rooted, ROM.

No root yet. Root just achieved on the S6 so hopefully the same exploit can be used on the S5 at some point. We'll see....

G920AUCU1AOE2 Odin Files Latest Update

Here's the full odin package for ATT S6 latest OTA update...that fixes battery drain by wrecking your signal! Enjoy
Link

IMO didn't fix or change battery drain either

Big difference...drain was ridiculous...Now after using greenify as well battery is 10xs better...thanks for the share

it's posible to have something like this for ATT S6 edge model? I've just post in the edge forum without lucky. thanks a lot

OE2 has definitely fixed the battery drain for me and signal has not taken a hit...

Do we ODIN all 4 files? Or just the AP file? Currently on OCE...

I had to do all 4 files with Odin 3.10.5

Does it really wreck the signals? Are you still able to keep root (PingPong root) after this update?
edit: PingPong root works with this version.
I don't know about the signals, but the battery life seems it does last a bit longer. But I feel opening the task switcher is kind of slower now.

Does this have to be pushed onto a stock ROM, or can we lay this on top of, say, a rooted AOCE build? In other words, do I have to flash all the way back to stock (and lose all my apps/settings) and then flash this, or can I just flash it over what's here (rooted AOCE) since it's effectively the OTA update in non-OTA form??

Hmm.. What am I doing wrong? 8:31 and 11% left with 2:35 screen on time.
I rooted and froze the crap out of AT&T bloatware. Not using Greenify at the moment because I don't think I need to. I do use Android wear, LG G Watch.
I disabled detecting OK Google voice command, and also disabled enhanced LTE related check boxes.
I'm currently on Tmobile, but will switch to AT&T soon.

I'm curious about this too - anyone know? Is this flashable over a rooted AOCE?

I have flashed this over a rooted AOCE and over a rooted AOE2 and all worked fine.

Can you use flashfire for this or is it strictly ODIN? On a mac so I'm having a hard time. Also, if you do use ODIN do you flash each through PDA?

Thanks to all the Developers!

Anyone have this available on a different site, mega doesn't work for me. I want to install OE2 then root, rather then use OCE rooted, and any OTA update seems to jump from OCE all the way to OF4 if I am correct.

So I haven't had to use Odin since my s3. I have an att s6 using it on Straight Talk and cannot pull ota updates....would I be able to just flash the latest ota through Odin or is root a requirement? Like I said I haven't used the program in years since this is my first Samsung device since the s3.

Once/if the tar is available you can just flash through Odin. Gotta wait for someone to post it up though.

I'm 99% sure it will work because they are literally the same phone. It's just different carrier settings.. In any case if the file is not compatible with your phone then it simply wont flash. No worry of a brick.

Is there a link available yet? Sorry for the rush but I'm pretty excited. (I can't pull the update since I have a T-Mobile SIM in my AT&T S6.)

The man, that is your title! THANK YOU! Us Cricket customers will be flashing shortly. I have AT&T device but Cricket service and the OTA just is not coming through.

Link is live everyone. PLEASE someone let me know if this wipes your data or not. Thank you and happy flashing

I'm having trouble downloading. I was at 0.5 GB/1.6 GB and the download stopped; now I can't even access the download page.
EDIT: never mind

Should I be adding all 4 files to ODIN? My biggest problem is that my phone is still on OE2 and I'm having problems updating.

Somebody pls make a flashable version of this so we can still keep root.

So this will burn a e-fuse? Is it supposed to? Does that hurt warranty as well?

e-fuse is samsungs way of blocking you from downgrading the firmware. This is official samsung software. You will not trip knox.

oh, I got confused. I thought the OP said our e-fuse would be set off, but he's saying it will be set off if we try and downgrade.
Does this update delete personal data? Or does it just update.

Dude thanks for posting these! When the 5.1.1 update was first rolled out I noobed it up and tried to get my device ready by flashing back to stock. It was rooted and on OF4 via the FlashFire method to keep root but when I flashed to the original stock it ended up wiping my baseband and as a result I lost data for two days. I just flashed these and now all is well again. Thanks again!

Ohhhh okay. I see now.
So it looks like a lot (I know, I had to flash it too), it's really not. So I need to know your baseband version to proceed. And no, you don't need root.

Okay you should be able to upgrade to MM without a hitch. I've done it before on my phone and can verify that it won't brick your phone.
BUT. It may wipe all user data, so make sure to back up EVERYTHING before proceeding (I lost some photos and memos in my upgrade because my backup software wasn't cooperating)
You should be able to just OTA to the latest MM build (Settings > About Device > Software Update > Check for update)
Keep in mind that if you OTA to MM, you won't be able to go back to Lollipop.
There is another way, but this is the easiest and what I recommend you try first because all other methods will upgrade you to a pre-release build.

FW-8.0.0] S7 EDGE SNAPDRAGON - UNIVERSAL OREO G935UUES4CRG3 July 1/2018 sec

I Downloaded The Fw From Sammobile, Yes Its Was Very Slow, Thats Why I Re-upped It Untouched To Androidfilehost, Much Faster To Dl For Others.
Only For Snapdragon Variants, Its The Universal Firmware, Its Free Of Carrier Bloat But Has Some Samsung Useless Apps.
Not For Exynos Variants Like The Sm-g935f, Etc.
MORE ABOUT UNIVERSAL FW READ THIS
The Zip Has The Att Extension But All Universal Snapdragon Fw Are The Same Afaik, It Does Not Install Anything Specific For Att,
Im On Telus/koodo Using The Sm-g935a Without Issues, Shows Lte Signal When On Data Mode.
Idk If Auto Updates Work, Although Update Options Are Available From The System Menu
Instructions:
Dl Zip, Extract Zip, Put Phone In Dl/odin Mode. Run Odin As Admin, And Load Each Cp, Ap, Bl And Csc(Dont Use The Home Csc As I Read Its Fracks Things Up), Just Use "Csc_oym" File In Odin
Fyi. I Used Princes Odin But Failed, Used Untouched Odin And It Flashed Successfully. Was On Nougat 7.0 Sim Unlocked SM-G935A At&t Branded Stock Fw. I Included Both For Your Pleasure.
Afaik It Will Wipe Your Phone, Do A Backup As Needed
make a backup by using adb, search for this method, and a twrp nandroid
always make a backup, and never just one, and save them somewhere safe in multiple locations and clouds, hard drives die all the time

Hi Vincom, yes i have already read the article. the main reason im flashing the rom is because of the hidden DATA icon in the toggle screen. and also i want my phone to have the OREO update as well. this is my first samsung phone. i have experience in flashing ROMs in my xiaomi redmi 1s phone. so im a bit skeptical if i can do this on my own. this odin process is very new to me. so what is the worst thing that can happen it i brick my phone? can i do a hard reset and will it default to the stock AT&T ROM if ever?

yes and no, csc controls what bloatware and which settings are setup by default dependant on carrier and country, hence why this is a universal fw and not dependant on original csc files.
if u truly have the att s7edge g935a, which is what i had, then yes.

yup i tried that one the first time. thats when it gave me the error message sha256. then i tried the prince odin that gave me the error mmc something.

The author claims performance and battery improvements but has anyone that switched over really noticed that big of a improvement?
I mean i already disabled all the carrier bloat with adhell isn't that basically the same as installing this rom? Does the universal maybe have a different kernal/different system level tweaks?

Bro , what will happen if my unlocked at&t s7edge installing this ? Is there sim will be locked again or not ? Thanks in advance and sorry for my bad english...
