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.

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.
network unlock code????
Here is the link to the tmobile original thread
[ODIN] Stock Nougat Firmware [SM-G935T] S7 Edge
Instuctions provided by jrkruse (original post)
1. You need to be on Verizon Beta Nougat 2
2. In developer options turn on OEM unlock
3. Reboot to download mode
4. Load the files you downloaded in the corresponding slots in odin BL,AP CP, CSC the files are labeled this way
you dont use the G935TUVU4BQB1_Boot_Recovery_Image.tar.md5 until later
5. Install with odin the phone will reboot to recovery to finish the csc install
6. If the csc install in recovery fails reboot to bootloader in stock recovery
7. In odin reflash the CSC file in the CSC slot in odin. The phone will reboot to recovery again and install the csc files
8. Once the phone is done installing and wiping in recovery try and catch the phone as it reboots and reboot back to
download mode (PWR+Home+Vol Down )
9. Use odin Install G935TUVU4BQB1_Boot_Recovery_Image.tar.md5 in the AP slot
10. Let phone reboot and go through setup
11. During Setup you may have trouble typing info in the setup boxes the keyboard has some bugs in setup. I recommend skipping
adding any accounts and do it after your through setup. Or use the alternative method to find your google account
12. Once through setup download 4G LTE Switch and use to Change Network to LTE/CDMA auto (PRL)
13. I recommend downloading Package Disabler Pro (It Works now) and disable all Tmobile Apps
I found samsung pay wasnt working I found that the tmb bootloaders and persist.img needed to also be flashed I made a new odin flashable package and install instructions. All seems to work now except of course volte and wifi calling.
Explanation why you need to be on nougat beta 2
Download:
TMOBILE_NOUGAT_VZW.ZIP
ODIN v3.12.3.zip
Possible Issues and solutions :
Q: after flashing the bootloaders and persist.img, it broke all data and calls and texts again.
A: they need to be all flashed at same time. Maybe Wipe data and it might work
Q: The Google "email or phone" text input box still only accepts one letter and any extra letters overwrite the previous letter typed.
A: The samsung keyboard will work fine if you just goto settings on the keyboard to language and types and change to US english.
Q: So the question is..... this worth flashing or wait for vzw?
A: Other than no volte this definitely the best running Rom so far. It is much better than beta
Q: 13. I recommend downloading Package Disabler Pro (It Works now) and disable all Tmobile Apps
Care to share your list?
A: List of Tmo apps to disable
Q: Except MMS isn't working, for me anyways. VoLTE isn`t working.
A: I got volte working and video calling maybe this will help mms for you
Download App shortcut maker from playstore
Select all activities find IMS Settings and create shortcut
Open the ims settings from the created shortcut
Choose Ims service switch
Click on MMTEL switch
Click on RCS switch
Under MMTEL section I enabled all the options
Q: Cant get this thing to flash CSC...just keep getting the dm-verity error 0x02.
A: 1:Flash all 4 files in zip.
2:let reboot and see if you get dm verity error.
3:if you get the error than reboot to bootloader and reflash all 4 again.
4:after it reboots again it will say error.
5:reboot to bootloader and flash the csc again.
Q: in 4g lte switch, i dont see the option for lte/cdma auto. could this stuff be because csc didnt flash correctly?
A: if you have the verizon data icons you know the 4g lte then it flashed correctly. If you see data icons that ate not verizon then it didnt flash correctly.
When every one is starting over are you flashing a pit file when going pack to ph1. If not you need too.
P.S. All credits goes to jrkruze. :good:
You mentioned to install Nougat beta first before installing t mobile firmware. Is that necessary? Also, any link for Verizon apn?

Look at you apn settings and just copy it. I didn't mention about to install nougat beta, I mentioned that it was installed successfully on nougat beta and that you must be on latest bootloader.
Okay so I have T-Mobile Nougat installed on my device, and I've changed my VPN over to VZWINTERNET, and I can't seem to get anything working (calls or data).
I'll continue to toy around with things though.

The T-Mo one you posted. Odin with ap,bl,cp and csc selected.
After toying with tons of things on the Tmo firmware, I tried booting into Odin, and flashing the Verizon pi3 CSC. That gave me a bootloop. I then tried reflashing the entire Tmo Nougat with Odin, but replacing the CSC again with Verizons, same bootloop. So now my phone is being flashed back to the trusty U MM.
I can only assume now that running the Tmo firmware on VZW will require root to make CSC edits. But Verizon will release our own Nougat before we get root.
Now I guess it's just a race between Verizon releasing 7.0, and the G935U getting it.
$50 on Verizon.
Edit: After flashing the G935U firmware again, after the first boot I was greeted with a message saying "your device must update to use new features from your SIM card." And I booted to a weird all blue screen with a big SIM card on it. I've never seen anything like that. I'm not sure if the Tmo firmware messed with stuff, so I'm going to fully flash the G935V firmware, THEN reflash the G935U firmware, just in case the G935T firmware messed something up.
they also did something to disable all package disabler apps even if you go back to MM they dont work. They screwed us goood on this
so @spiderkr were you able to get it working or just going off of other reports?

Beta 2 Verizon Nougat
Unable to select network
Under "Network Operators" I selected Verizon Wireless, waited 5 minutes, and now got Unable to select network. Then, maybe a minute or so later, it says "Unable to connect. Try again later." Is there a way around this?

G930U phone. Nov 1 Android update from Samsung, installed as normal. After reboot got the typical hung phone problem with switching SIMs. So rebooted in menu mode and normal boot, no resets, which fixes that first issue. But now no data connection on Verizon network with Total Wireless. TW tech support is useless. Anyone else?
Could be that the update broke your CSC somehow, which is where all the carrier network settings come from.
Try going to updato.com, finding the right firmware for your phone, and flashing just home_csc via Odin, there is a flash guide on the site. If TW has their own firmware variant, use their CSC.

Thanks for the response. Always appreciate the input. I should have mentioned I'm on pure stock, not rooted, so re-install firmware would be a biggy for me.
Turns out after over an hour on chat and phone with TW and Samsung the fix was to do turn off mobile data, "Reset Network Settings", then "Search Networks", reboot and turn on mobile data. LTE popped up on the status bar and there's joy again.
Hope I remember this after the next update from Sammy.
No worries glad it's sorted.
For future reference in case you run into a pickle, flashing via Odin doesn't require root or trip Knox, and won't break warranty. It can be used for 100% stock flashing in the event you have issues, or want to upgrade/downgrade.
Flashing home_csv specifically also doesn't wipe your phone.

That's very good to know. I've done no flashing of roms but what you just described could turn me into a "flasher", uh, so to speak...
Thanks.
Update: Not fixed. Now I can either use calling or data, not both. Samsung said the update reverts APNs back to default. Apparently that removed the Total Wireless APN, but there's no way to manually enter or edit their APN. Auto select network doesn't solve it. Still looking for an answer.
Hello.
Got a free phone from a buddy S21 5G. I am wanting to swap it for the S10* 1tb I gave my wife to use it was a bit expensive. So I'd rather ti go back in the box.
Popped the sim in it, it works makes calls sometimes, sometimes not. Texts seem to always work, I am currently on ATT I would prefer to have that firmware as I live in the stick with ho cell service. ATT has wifi calling which is pretty much a necessity here.
So what exactly do I need to do to get this off the VZN fir
Hello. Could you all provide me the links for what I need? Found a link that had a patched Odin plus the firmware. I installed in booted how I was suppose to. Tried to install in and it errored out. Also. I do not know what file to select for the user data selection, I do not mind deleting all data as it 8s hacked up and can put ti back with smart switch.
Hello, did you manage to flash the phone?, I'm stuck with a similar case, mine is a factory unlocked unit from Verizon, it turns out that even if it is factory unlocked, is locked after a few minutes by verizon, I have tried everything to get rid of the VZW firmware but it seems that Verizon locks the bootloader so I can't flash it (it passes om odin and everything but the firmware doesn't change)
I even paid SamKEY credits to change the CSC but it didn't change either.

Hey, first post so sorry if I say anything off lol.
I have a G996U purchased from Verizon that I flashed to U1 firmware like 2 years ago when I first got it, and have had no issues since. I had a OTA software update the other night that seems to have triggered a carrier lock in my phone. The phone works fine for 5 minutes, then I get a popup telling me the phone is locked and to contact Verizon, despite the phone being from Verizon and running a Verizon sim. I went to them and unfortunately nothing they did could resolve it (new SIM, eSIM, etc), so they shipped me a new phone via insurance. I'm wondering though if I could save myself the hassle of transferring everything and do an in-place flash on the phone to see if that clears up the issue. I am already on the newest firmware (G996U1UEU5EWB1), so I can't upgrade, but I was wondering if I'd be able to flash the same firmware already on the phone while keeping all my data. Thanks.
Yes, just flash with home_csc.

Thank you, just also want to ask bc I'm actually not sure which software to go for. I thought I had flashed XAA long ago, and I'm definitely on U1 firmware, but when I check "Service provider software version" in settings, it says VZW rather than XAA. Is it safe to download XAA firmware for a reflash or should I just do VZW to be safe?
You can flash any csc firmware.
