AT&T Note 8 on T-Mobile - AT&T Samsung Galaxy Note 8 Questions & Answers

Upgraded to Note 9, want to pass my Note 8 on to a T-Mobile user. I want a complete T-Mobile experience, so all T-Mobile bloat and settings are needed (VoLTE, Hotspot, etc...) . Note 8 currently has latest CRID OTA from ATT. Looking for help in determining the correct way to proceed. I am having AT&T carrier unlock the device, so I would make this change after confirmed unlock. Also, once this is finished, will the device receive T-Mobile OTA updates?
I have read through https://forum.xda-developers.com/galaxy-note-8/how-to/guide-sm-n950u-u1-t3685884 but am confused. I see lots of mention of combination files, CSC changing, etc... that seem overkill for what i'm looking for.
Are these the steps I need to take?
1) Download latest Odin compatible TMB Firmware (which is what version?)
2) Download Odin on PC
3) Factory reset Note 8
4) Flash TMB firmware
5) Insert TMB SIM card
6) Success?

Yes just download this file

I saw here that simply flashing a different carrier firmware will not actually change carriers?? Is that correct?

Someone in that thread said I would need to flash an unlocked U1 firmware and then the TMB firmware?

I am about to do this as well, switching from AT&T to T Mobile using my AT&T branded Note 8. I just wanted to confirm that it's as simple as downloading the latest Android Pie firmware for T Mobile and flash it to the AT&T branded phone? Any precaution like some other thread mentioned to flash the U1 (unlocked) firmware first then flash the T Mobile firmware?
Also, eventually, I will be giving this Note 8 to someone in China. At that point, is it better to flash the unlocked version of firmware or just leave the T Mobile firmware on it?
Thanks so much for your help.
Note: the phone is already unlocked.

I just wanted to let everyone know that I went and got T Mobile. After the new SIM card was inserted in my AT&T Note 8, after a reboot, it did something, a screen with a SIM car graphics and some moving dot. Then it rebooted itself again, and then T Mobile splash screen showed up. It even added the bloatware from T Mobile. So, Android 9 for Note 8 probably has both ROMs? I also checked the firmware version. It shows the latest T Mobile ROM.
I didn't have to do anything other than just inserting the new SIM card from T Mobile.
This is very interesting to me, and the store guy couldn't believe his eyes either.

And i was wondering why my phone still showing at&t bloatware even after installing the Verizon firmware. ? Now i understand Cuz I'm using at&t sim. Good to know?

Another update!
I just got updated by T-Mobile to the latest firmware after converting over as previously stated. I have to say that the update page on the phone for the T-Mobile firmware is MUCH nicer and informative than the ATT version. It tells you how much time left, the version numbers, and even a "what's new" section...
After this update, my phone is actually better at battery usage.

Screwed up my SM-G930VL, please help!!

Hi,
I bought a SM-G930VL (tracphone branded, but verizon compatible) galaxy s7 for a pretty good price, however the advanced and wifi calling were not options (even though verizon told me they were before I purchased). I decided I would try to flash the VZW firmware from sammobile through odin, but it did not work. It originally gave me the ext4 error, but then flashing the csc fixed that. I then flashed the AP file, but it finished very quickly (about 3.5 min) and now will only boot into recovery when powered up.
Is there anything I can do to save my phone, or have I permanently screwed it up?
Thanks
holy sh*t got it working. Flashed the BL, AP, CP, and CSC files and it booted to welcome screen!!
Thanks all (and hopefully this helps anyone in the future who runs into this predicament)
It is currently checking wifi connection so hopefully all is well!
Edit: Is there a way to edit the title? That way this could be maybe help the next person rather than getting ignored.

Hi, want to ask a few questions. were you able to fully flash the Verizon firmware to this model with no issues? The phone is also supposed to be factory unlocked per my connections with reps.
Did the phone fully change to a SM-G930V, showing in settings and in Odin mode?
Yes I was able to fully flash Verizon and I have working wifi calling and advanced calling. In settings it shows up as V not VL as well. As far as I understand it is the exact same hardware just different software running on it

Great, i flashed one yesterday for a friend via teamviewer and even changed the model as SM-G930V in odin mode. So I guess due to this the phone has now a locked bootloader and ended up being converted to a full Verizon galaxy S7. Only thing it did not take his Metro PCS sim card. Unsure it would take any other carrier sim cards.

Was the boot loader originally unlockable? I was under the impression that all SD versions were locked down right. That's great that you got it to work also!

It seems it was as it allowed me to flash the verizon bootloader and full firmware. Normally tracfones only allow to flash part of a firmware and rejects all bootloader partitions.
Is bootloader locked after flash g930v firmware. Or can I flash back to straight talk?

There were reports of someone flashing the phone to an SM-G930U (Unlocked US S7). So apparently they are interflashable. I however have not gone to that extent as am yet to get my one to thinker with. I flashed previously to a SM-G930V via teamviewer for a friend. You can search the threads and verify.

You probably figured it by now, but MetroPCS is the only retarded carrier that locks SIM to IMEI. So if you want to use MetroPCS on any other phone than the one you currently have it on, you need to call customer service and give them your new phone's IMEI. Then your new phone will start working. If you want to switch back to your old MetroPCS phone you need to call them again and give them that IMEI, which is retarded. I don't know why they do that but it's really annoying if you frequently switch phones.
I have a 935V (S7 Edge Verizon) and now have 935U ROM on it using Tracfone. Initially I have Tracfone's Verizon service but I wanted the freedom to easily move from one phone to another so I converted it to a Tracfone-GSM(ATT) and been using it in my Verizon S7 Edge (with 935U ROM) and iPhone SE without any problem.

Could you add links to everything you used? I have the same model using straight talk and I want to be able to have a backup firmware to flash in case I ever mess up my phone (which seems to be a trend). And have you had any issues at all? Like, does everything work okay?

I too would like to know if you could please provide links. Im rather new to this, the only other phone ive ever flashed rooted and put custom rom on was a Evo. But alls im looking to do is get my s7 rooted and it would be nice to have it flashed to Verizon first seeing as there root guide is for verison phone and firmware.

[UNLOCKED] SM-G935T / T-Mobile

Hi community,
A question for many of us in regards to 'unlocking' or "how to unlock" from our carriers, I have done a very simple and silly way to unlock my phone from T-Mobile.
I am currently under SM-G935U Firmware (4API3), coming from SM-G935T's 4APIA Firmware.
Follow these simple steps in order to unlock from your carrier.
***NOTE: THIS METHOD ONLY WORKS IN STOCK FIRMWARES. YOUR DEVICE WILL BREAK IF YOU TRY TO INSTALL UNDER A CUSTOM ROM***
1.- If you have previously installed a custom ROM (Echoe, Tekv2), say bye bye for now. Using Odin latest version (3.12.3), flash Stock Firmware '4APIA'. After set up enable developer options and USB Debugging.
2.- Download SM-G935U's official firmware from SamMobile or Samsung-Firmwares (Make sure you download the TMO region firmware)
3.- Create a new folder on your desktop, copy and paste BL & AP files from the SM-G935U firmware you just downloaded. From the SM-G935T stock firmware you downloaded, copy and paste CP & CSC_HOME files.
*Basically you will have BL/AP from G935U and CP/CSC_HOME from G935T*
4.- Flash these files through ODIN, but WARNING: After flashing your phone will reboot. Go into recovery mode and wipe cache/data + wipe data.
5,- You will get to see a dm-verityverification failed, no mount blah blah blah. Just ignore it. After deleting cache and data reboot again into download mode...BUT THIS TIME ONLY FLASH CP file from G935T while the CSC_HOME you will flash now will be the official G935U file.
6.- After reboot, done.
I was able to install Google Voice
Sounds promising going to try this when I get home, was having all those issues with dm-verity.
Have you tried just wiping the cache and not wiping data with success? (Dirty flashing)
Or we all starting from scratch?
since root with eng kernel makes my phone burn up and kills my battery, even with all the remedies. The g935u is an option I would love to play with.
But how did you unlock the sim? You have the unlocked versions firmware so less bloat and no carrier garbage but the phone itself would appear to still be locked to TMO. Splain.
Hi there. This firmware is so much better than the stock TMO firmware, everything works excellent. I used stock tmo firmware first APIA, next tmo G935U API3 next. I tried your way first on a S7 Edge with bad IMEI and it wasn't working. I used another S7 Edge but this time I flash all the G935U API3 firmware, it work flawlessly with one simple try. Just put AP/BL/CP/CSC and flash with the latest Odin, you wouldn't have problems. My 2 other TMO S7 Edge are on stock G935U and saying official.
Hey can make a video like you did please.

Yes indeed it is. G935U feels great, faster response, no lag at all and for some reason I get 4G LTE even with Roaming (Mexico) I am still with T-Mobile...were you able to UNLOCK the SIM?

Hey bori,
Every time I flash a custom ROM or even going back to stock, I always wipe cache/data. It is just the way I like to do things on my phone, not keeping any traces from previous ROM/FIRMWARE.
Make sure you download the official Firmware from SamMobile or Samsung-Firmware.
I heard updato is a fast download Firmware site.

Well i tried last night but ended up with the same results. Goes perfect in Odin. But boots straight into recovery even though I wiped everything and reflashed cp and home csc from g935t files.
For the TMO and other SM-G935 firmware, check out THEANDROIDSOUL.COM . They have about 90% of all firmware.
---------- Post added at 11:02 PM ---------- Previous post was at 10:40 PM ----------
I'm not a big fan of stock roms, custom is the way but this TMO G935U FIRMWARE IS THE ****TTT !!!.
The last time I used a stock Rom was from HTC EVO 4G, after that was the Sprint S2 and I never USED ANY PHONES WITHOUT A CUSTOM ROM TILL NOW.
This TMO G935U FIRMWARE, I did a ANTUTU BENCHMARK LAST NIGHT after flashing the firmware. Mennn! The score was higher than the note 7 N9300 by 4000 points, I couldn't believe it. I did a second test samething. The battery performance is excellent.
All mine said was applied multi csc now I get lte+
Nah I didn't try to unlock it yet, I have to get an AT&T sim card or simple mobile card and see if it ask for codes. If that works that will be great for everyone ?.
Which U firmware are you guys flashing and what would be the differences between them? I'm currently on the T-Mobile U firmware.
tried this... asks code also ... but anycode can give message "network successfull".
BUT its not unlocked... still "invalid sim card inserted error" is there.
So this method works or not? I want to know before I take the plunge. Also Dm verity error doesn't sound good either. I had a note edge with that error and it was a major headache.

i was able to flash g935u firmware totally.. but didnt work for me.
Hi all. As far as I can see, the U firmware unlocked the phone. I inserted a SIMPLE MOBILE CARD into my G935T running G935U firmware, the phone boot into like recovery mod but the screen go BLUE and it configures SIM UNLOCKED SYSTEM, then it reboot and walla the phone have service on SIMPLE MOBILE NETWORK. I was very SURPRISED it works because the phone is locked to T-Mobile and only the DEVICE APP to unlock it. So at this point I'm only using the G935U firmware on my G935T, no more T-Mobile firmware bull crap. Next I'll get an AT&T SIM card and try that for 30 days.

I know this is a late response but it's good to know. SimpleMobile has been running under T-Mobile Network, whether your T-Mobile Phone is locked or unlocked it will work when a SimpleMobile Sim is inserted.

Convert SM-G930T to SM-G930A so I can use AT&T LTE bands.

Hi All, I want to continue using my AT&T prepaid plan but I recently bought a locked T-Mobile Galaxy S7 SM-G930T (I'm going to try to unlock it - if that doesn't work this is all moot). I would like to flash AT&T firmware so I can use the AT&T LTE bands. Can I follow the instructions in the link below once I've unlocked a T-Mobile SM-G930T and turn it into a SM-G930A?
http://www.droidviews.com/nougat-firmware-on-att-galaxy-s7s7-edge-sm-g930a-g935a/
I've read the link below... but it seems to be only if you want to continue using T-Mobile service which I don't.
https://forum.xda-developers.com/tm...w-to-flash-att-nougat-to-t-mobile-s7-t3553610
Changing firmware doesn't have anything to do with what bands the hardware supports. Unlock it and throw the ATT SIM in. Only difference is carrier supported features and software (wifi calling, etc). Flashing ATT modem might improve coverage but all S7 support the same bands.
Thanks buddy for the reply. I'm used to using a custom ROM on my Android phones so this is new. Mostly CyanogenMod.
That's good to know I don't need to flash in order to get the bands but I understand I need to if I want OTA updates from at&t. It seems relatively simple that you just flash the AT&T ROM over the T-Mobile with Odin and then use some update file. It doesn't even effect Samsung pay and Knox which is great.
Stupid question: is the AT&T modem included with the AT&T rom? Also, with regards to the 2nd link in the OP what is the update file that you put on the sdcard to use in recovery - is that an OTA update because your ROM is different from your carrier?

I don't get why you would do this other than to have ATT bloat over TMO bloat (IMHO TMO has less bloat than ATT). There's no technical advantage. Am I missing something?

The amount of bloatware is irrelevant since you can freeze all bloatware on either build. I experienced many issues on the TMo version including issues with Android Auto, Google Assistant, and Tasker. I thought these apps were buggy but all of those issues were resolved on the AT&T version. The AT&T version seems to be a better, bug-free build.

Read that in a different thread you posted to after I responded. I think it's very YMMV though. But if you saw improvement then ??
Hi, did anyone ever complete this flash from SM-G930T to SM-G930A? I'd like to do this solely to try and get the wifi calling feature since my workplace has poor cell service but great wifi. I bought the T-Mobile phone, unlocked it, put the ATT sim in and everything but wifi calling works fine. I appreciate the reply!
This is much later in the year (11-8-2021) and ATT has posted the list of phone they say will work and it only shows G930A. It seems their test of working means it must have been sold by ATT. They say My G930T won't work. So Will ATT continue to use customer's unlocked phones it they were not orginally sold by ATT. They have the records. Will ATT refuse to use one of their SIMs even if the phone is Flashed to ATT logo. I do not want to throw away my G930T phone.

Hello and thank you. You posted this information and link back in 2017 and so much has changed. Mostly ATT is now working hard to get rid of all 3G towers and firing up 5G. They said my Galaxy S7-GM930T would not work so I think they link you posted will help me convert the phone back to a GM930A or U or U1. My question is,..Has anything in your post changed since 2017 and if so could you please advise me of what I need to do. Thanks very much.

They said my Galaxy S7-GM930T would not work so I think they link you posted will help me convert the phone back to a GM930A or U or U1. My question is,..Has anything in your post changed since 2017 and if so could you please advise me of what I need to do. Thanks very much.

Sprint S8 Active flash to T-Mobile?

So i've read that the sprint version of the S8 Active is on bootloader v5 and the T-Mobile version is bootloader v1. Is it then possible to flash the T-Mobile firmware onto the Sprint Variant ?. The device is already unlocked but i would like Wifi-calling to work for T-Mobile.
Edit 1: Found this and successfully fully flashed from Sprint to T-Mobile(everything works including Wifi Calling). Only works if you are on bootloader version 1.

I AM NOT THE CREATOR NOR DO I TAKE CREDIT FOR THIS
No apparently the bootloader version must match or be lower so in this case sprint is higher so you can't flash. I've tried and downloaded the tmobile oreo firmware; you'll just get a fail in odin

That is the part i am maybe not understanding. My Sprint S8 active says it is Software version G892USQS1ARC1. Doesn't that mean it is bootloader version 1?
Sorry I was wrong! I actually flashed it! Very happy right now. I was being stupid and using an older version of odin before. Now I successfully flashed sprint to t-mobile oreo with no problems! Use Odin 3.13.1; not prince comsy mod or anything else. So it was bootloader 1 after all; there were some misleading posts without proof. I will trust the software number from now on

ARE YOU SERIOUS?!?! Does wifi calling work for you now?
I'm not sure. How can I check? I'm on Fido which is Canadian carrier without WiFi calling. I'm guessing I'm supposed to be looking for a tmobile WiFi calling app. See attachment screenshot for proof. Still recognizes my phone is from sprint
Yeah i just finished flashing it and i get the same as you. Phone still recognized as Sprint and no WiFi calling. Darn. Android 8.0 Oreo is a huge plus however.

I think we need to follow this guide to change carrier but the thing is there is no factory binary for the s8 active so this guide won't work until there is one...
https://forum.xda-developers.com/galaxy-s8/how-to/switch-to-carrier-firmware-100-t3609487
Actually I have found and flashed a factory binary trying to change it to T-Mobile. The problem I ran into is they want you to download the firmware with "w" after the model number. That is what I think let's you change the option after typing in the code. That firmware is only for s8 I think(not active as it has the s8 model #). Without flashing that, after I typed in the code the only option I had to choose from was sprint. No "xac" or whatever it was.
If I am not mistaken. The model with the "w" is the Canadian version of the s8. The s8 active is US only I think.
So Im getting ready to pick up a Sprint version to use on Att or Tmobile (good deal). Are you guys seeing any issues after flashing? Thanks

The only thing I've notice is there is no option for mobile hotspot( i don't think it was there to begin with, i could be wrong however). Other than that it works perfectly. Great battery life and everything. Flash the userdata to get rid of the Sprint Boot animation if you'd like. I did it and now there is just the "Samsung s8 Active" logo, then lock screen. Goodluck.

After flashing Sprint variant of the device to T-Mobile firmware, do all features work: WiFi Calling, Band 12, VoLTE and Band 71?

WiFi calling works fine on T-Mobile without flashing to T-Mobile firmware. Only issue is that sometimes it gets stuck enabling WiFi calling requiring a reboot. Band 12 also works, its in the Sprint specifications. The big question I wonder about is if band 71 can be enabled.

Did you follow the video I posted?. Ignore all the other comments about things not working. When i updated the OP with the link, it fully flashed the sprint device to T-Mobile. The only thing you have to watch out for, is if your Sprint software is running a new bootloader. You can tell by looking at the baseband version number. This will only work if you are on bootloader 1. My baseband is currently "G892USQS1BRD5". The bootloader version is the 5th character starting from the right. The number 1 before "BRD5".

Question Can't change CSC from T-Mobile to Verizon with firmware S908USQU2AVDC

A question from a noob here. I have a T-Mobile S22 Ultra phone which is network unlocked. As I recently I switched from T-Mobile to Verizon, I'm missing some of the features that are Verizon specific, while not needing anything that is T-Mobile specific anymore. From what I understand, Samsung installs multi SCS firmware on most of the phones these days, which can be changed by a dialer code. That however did not work at all.
Another option I've come across is by flashing provider specific (in my case Verizon) firmware as long as firmware version is the same (S908USQU2AVDC). There are a number of articles on how to do it by using Odin. The issues is no matter what I do and what files I select (like by using CSC file instead of HOME_CSC with or without flashing USERDATA file as well) the result is the same. It shows success and reboots and then reports an error and does the full factory reset which ends up back on T-Mobile version.
The question I have if it's even possible? And if so what I'm doing wrong here. Unlocking a bootloader is not really an option for me...

In theory, flashing the correct firmware (VERIZON) should work. I would honestly first wipe the device, then flash (clean, not dirty) the Verizon firmware and setup accordingly. I had a similar case with a TMBILE unit (I had changed carriers) and I had managed to use XAA CSC and then when I reverted to TMOBILE SIM it would not "restart and install carrier updates". I had to basically switch the unit to U1 and then revert to U and it finally pulled all the TMO crap.
I may be mistaken since I haven't done this type stuff since S10, but I think you need to first reset the device and flash the unlocked version then when you put the verizon sim in it should provision it. Then you can flash the verizon package if you want the bloat apps. The features may be hit or miss. You may need to activate the features on the verizon website. Some features may never work as the carrier wont push them to IMEI not in their database of branded phones. There may be things you can do in hidden settings with "Activity Launcher" or other methods.
I'm here trying to figure out the same things for Tmobile and a factory Unlocked phone, before I buy.
Thanks a lot for your suggestions guys! I managed to do what I wanted. This is what I ended up doing, first flashed the unbranded U1 version on my phone and on the first boot Verizon sim was provisioned. Then I flashed Verizon firmware and it worked!
