When I go to the Access Point Names menu, I see it already has one called lte.vodacom.co.za (Which is apparently correct) - I guess it's pulling it from the sim card?

I also read online that vodacom has another access point called "internet" with a username as guest, so I've tried that and rebooted: still nothing. I also tried without the username.

When I go to network operators it shows me all the networks around me, from all the different companies (about 6 of them) - so it is finding them.

Here's another observation:

There is definitely excellent signal on all networks where I am - my wife has an asian Exynos based dual sim Note 8 and it works fine with all these sims I'm testing - full signal.

When I insert a sim from another carrier (MTN) into my phone - instead of the empty (no signal) triangle, I'm sometimes getting a circle with a line through it. But not always. Also, right now it doesn't say (No Service), but I have no bars of signal and cannot do anything.

I also notice that the Access Point is immediately changed to "myMTN" when I insert the sim - I rebooted and still no luck.

---------- Post added at 05:51 PM ---------- Previous post was at 05:40 PM ----------

I've also noticed something else..

When I go to network mode, I can select:

LTE/3G/2G (auto connect)

3G/2G (auto connect)

3G only

2G only..

If I select the "LTE/3G/2G (auto connect)" and then click on Network Operators and "Search Networks" it returns all the networks around me (six of them) - but none work.

If I select any of the other 3 options above - like "3G/2G (auto connect)" - and then search networks - it finds nothing. So it seems that only when it's on LTE mode does it even see a network.. so I'm guessing all the non LTE bands are not working?

EDIT: There is another carrier here called telkom that uses LTE 40(2300) which I've not tested yet. I'll try get a sim from them.
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
That would explain no bars if your carrier doesn't support VoLTE or HD Voice. You might want to give them a call and see. IMS settings can impact VoLTE and HD Voice and those settings are hidden within one of the dialer code menus.
[Samsung Galaxy Note 8 Guides, News, & Discussion] Neverwhere20:
I just got off the phone with Vodacom and they said the VoLTE was provisioned on my sim - but they are attempting to reset it by unlinking my number and relinking or something. They told me to pull the sim out and wait about ten minutes and then re-insert. If this doesn't work I should take it into a store and see what they say. Not sure they'd be of any help - I'm weary to even begin to mention anything about flashing unlocked firmware lol.

Thanks again for all your help! I'll update if I get anywhere. I still need to test a sim from Telkom.
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
Flashing the firmware isn't anything uncommon. Using Samsung official firmware, the U1, U, and W models are all the exact same hardware. Taking it into a carrier store, I doubt they would eve notice the firmware being different. I hope you get it working. If not, maybe flashing the W firmware might be worth a try.
[Samsung Galaxy Note 8 Guides, News, & Discussion] Neverwhere20:
Thanks :) I've tried the W firmware - N950WVLU5CRI9 (Canada - XAC) - still not working, though it did give me different options in the menu. Instead of LTE/3G/2G, it had WCDMA/LTE/3G I think, as well as 3G/2G only. Also, on this firmware, I could use *#2263# to get the menu that lets me disable certain bands. I tried a lot of different variations and what I noticed is that LTE at least gets a bar of signal some times, but it doesn't register on the network, and it mostly settles on "No Service". 2G/3G doesn't work at all.. just straight up circle with a line through it.

Not sure if it's worth trying other W firmwares - I'm downloading some just to see what happens (they just take a while to get - internet is crappy here lol)

I'll be going into a store tomorrow to see what they say. Thanks again for all the advice!
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
WCDMA isn't in use many places anymore but it might be of use in some places where cell technology is still way behind the rest of the world. The W is pretty much a generic U1 but for Canadian carriers. The versatility of it isn't bad. If you take it to a carrier store, hopefully it's something simple we are all overlooking. If not, maybe try multiple different carrier stores while you are out and see if one carriers reps might know a bit more than others. The frequencies there are standard for the most part. Maybe see if any of them are going to roll out something new or if they have a SIM on hand you can try to see if you happen to get working service on.

Another possibility might be to look into some European carrier roaming packages and see what bands and tech they have deployed there for roaming use. EU and UK carriers tend to have a lot of great roaming options that might give you service there as a possible alternative.

Thanks for this awesome guide. I was able to successfully go from AT&T note 8 to T-mobile note 8. All the network features are working too.
[Samsung Galaxy Note 8 Guides, News, & Discussion] sixtythreechevy:
I have this same exact issue. I have not flashed anything using the carrier switching method. I have a Verizon Note 8 Sm-N950u. I recently switch to red pocket (RP) and am unable to get VoLTE to work (RP

does

support VoLTE) as I don't even have the option. I flashed the latest update CRID with Odin 3.13.1. When I go into settings, connections, mobile networks, all I see is Network mode (CDMA/EVDO/GSM/WCDMA) and there is no option for HD / Advanced calling. From what I've seen others (non RP) are having this issue were able to change the Network mode from Global to LTE/CDMA and this fixed the option for Advanced Calling / HD / VoLTE not being there. Which led me to this thread as my CSC reads vzw/xaa/vzw and I'm wondering if that somehow got borked (technical term, I know). I'm desperate for help but I'm wondering if I would be able to flash the correct CSC, or go back to an earlier version of Android, or something. I'm stuck. If it truly is because of the SIM I'm done with RP but I will have to wait until my 1 year of service is up as I am not going to pay for another service until that is used. FWIW, my son has a el cheapo LG phone and his advanced calling works fine on Nougat. So it seems that this is an issue with Oreo and the RP SIM. I believed this all worked on Straight Talk but I think I was on Nougat when I was under Straight Talk.

I would appreciate some help/clarification. I currently have a note 8 on sprint running N950USQU5CRIA and was wondering if its possible to switch the carrier to tmobile.
[Samsung Galaxy Note 8 Guides, News, & Discussion] oZo:
carrier finctions?

*If you are going to proceed to flash carrier CSC and USERDATA files for carrier functions, please make sure that they are from the appropriate SM-N950U carrier before proceeding...*

is this a step to be done AFTER flashing the unlocked (XAA) firmware, or are we to substitute these files in the initial Odin flash?

Thanks.

Never mind, I figured it out...Use Prince Comsy to flash the userdata AFTER the initial flash.

[MENTION=5649240]BlueFox721[/MENTION] or anyone

I have a Galaxy Note 8 on unlocked v4 bootloader. I finally got a hold of the following two files:

COMBINATION_FA71_N950USQU4ARD2_CL13471319_QB17840698_REV00_user_mid_noship_MULTI_CERT.tar

HOME_CSC_OYV_N950WOYV4CRF1_CL13670227_QB18370393_REV00_user_low_ship_MULTI_CERT.tar

Will they work to Switch Carrier from unlocked to AT&T on Bootloader v4? I ask because the Home file is 4CRF1 and the Combination file is 4ARD2, so they are not the same carrier files. Will they work to switch carrier still?

Thank you
[Samsung Galaxy Note 8 Guides, News, & Discussion] buddha5955:
Hey thanks for this information. I went ahead and downloaded the U1 OS for the S9 model and threw it all to the wind last night and everything went wonderful...seemed a lot smoother than previous models as well. It does help that there are not too many builds for the S9 right now.

Thanks again!

Have you tried simply putting a t-mobile SIM in the phone? If it's unlocked by Sprint, it should auto reconfigure with the T-mobile firmware/apps after switching the SIM.
[Samsung Galaxy Note 8 Guides, News, & Discussion] DeathGrin13:
nelms, were you ever able to find the csc file? I desperately need it!
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
The carrier firmware does restrict what bands are implemented regardless of what SIM is inserted. SIM unlocking their device would be the place to start, then converting to the U1 non-carrier firmware first and not using the HOME_CSC, then flashing to TMB U if they want all of the T-Mobile features, like Video Calling. WiFi Calling for T-Mobile does work on the U1 non-carrier firmware.
[Samsung Galaxy Note 8 Guides, News, & Discussion] andrewNY:
Since Oreo, the device will auto-reconfigure with a new SIM, including all the required bands. (link is to a post about the S8, but this feature is now on the Note8 as well).
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
Interesting! I wish they would roll that out to the S9 and Note 9 as well. It sounds very similar to the Canadian W firmware, where it uses Google services to download and install bloatware based on the SIM during setup.

I was finally able to switch my Note 8 from unlocked to ATT firmware. (was not an ATT phone so had to follow switch carrier guide) I ended up using the below files for the switching carrier guide then just downloaded ATT Oreo firmware with Bootloader v4

COMBINATION_FA71_N950USQU4ARD2_CL13471319_QB178406 98_REV00_user_mid_noship_MULTI_CERT.tar

HOME_CSC_OYV_N950WOYV4CRF1_CL13670227_QB18370393_R EV00_user_low_ship_MULTI_CERT.tar

I also used Odin3 v3.13.1_3B_PatcheD for everything. Ran it as admin. I tried the other Odin versions but none of the others worked. Let me know if anyone needs me to link the files. The Combination file I found on here and the CSC file I followed what [MENTION=5649240]BlueFox721[/MENTION] said and downloaded the Canadian XAC v4 firmware from updato and just extracted the CSC file.
[Samsung Galaxy Note 8 Guides, News, & Discussion] dwalkingdead:
I have exact same issue as you. My note 8 is a Verizon and reads vzw/xaa/vzw. I'm not sure what happened but when I took my phone to repair the screen at Samsung warranty center, they updated to latest firmware. According to them it was Samsung's policy. This is when my phone was switched to vzw/xaa/vzw. I always thought that this happened because I did switched firmware to unlocked (xaa/xaa/vzw) version once then switched back to verizon firmware (vzw/vzw/vzw) before I took it to service center. Funny thing is that I never expected as you pointed out because of Redpocket sim. My wife has the same verizon Note 8 using Redpocket sim as I do. Her phone was never switched or updated to different firmware. Her phone shows vzw/vzw/vzw using Redpocket sim. I was able to switch from unlocked version to verizon version (vzw/vzw/vzw) when my bootloader was v3. After the update, my bootloader is v4. From what I'm understanding v4 can't do switch carrier. Correct me if I'm wrong.
[Samsung Galaxy Note 8 Guides, News, & Discussion] sixtythreechevy:
I'm assuming you went to Oreo at the same time as the v4 bootloader? I believe that there is no way to go back to Nougat/v3. I'm not sure about carrier switching with v4.

Yes, went from Oreo v3 to v4. I just want to make my phone change from vzw/xaa/vzw back to vzw/vzw/vzw. Don't know how to do this. Let me know if anyone has the answer.
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
Switching firmware is fine on the v4 bootloader. XAA can sometimes show up in the middle when you are using the U1 non-carrier firmware that was flashed without your SIM in the device, but put your SIM in later. Using a combination firmware could also have this happen. I would flash to the U1, don't use the HOME-CSC so it wipes with your SIM in it, and then flash again to the VZW U firmware. That should change everything to VZW/VZW/VZW.
[Samsung Galaxy Note 8 Guides, News, & Discussion] dwalkingdead:
Just want to confirm.

1) Are you saying flashing my verizon (vzw/xaa/vzw) to unlock version (U1) is ok even when I have bootloader v4? I thought you can only do it up to bootloader v3.

2) If I flash it to U1 and not use HOME-CSC, do I use CSC for CSC or nothing for CSC?

3) Flashing VZW U firmware: Last time I flashed from unlocked U1 to VZW U firmware in bootloader v3, my phone did not simply switched back to VZW/VZW/VZW. I had to do a SWITCH CARRIER method. I am not able to perform switch carrier because there is no COMBINATION file for v4. I did not have my SIM in it when I flashed this method. Would I be able to get back to VZW/VZW/VZW simply by flashing VZW U firmware?

Thanks for your reply and appreciate your help.
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
There is a v4 bootloader U1 XAA, N950U1UEU4CRD7. That is what I used to flash my mother's Note 8 quite a while back. You can not flash to an earlier bootloader number, so v3 bootloader firmware will not work. The 4 in the last five characters, 4CRD7, is the bootloader version.

Hey guys, I am having trouble activating Factory Unlocked Note 8 on Sprint network.

First used on T mobile and now ported over to Sprint. But it is not getting any services at all. Sprint tech support is telling me the phone is international model for GSM only.

I contacted Samsung with the IMEI and Serial. They told me the phone is XAA model, factory unlocked for all carriers, Samsung USA model.

Phone shows Sprint on the top left , signal bars on the right, settings shows the Sprint phone number.

It is on Android 7.1.1 and is not getting any software updates.

Baseband version N950USQU2BQLA

Build number NMF26X.N950USQU2BQLA

(Is this because it was on tmobile network? I googled and it seemed like a tmobile)

I read somewhere that android oreo introduces automatic carrier switching?

Please correct me if I am wrong:

Using Post#4 Flashing Unlocked Firmware,

1- Use Odin3_v3.12 (PrinceComsy) <--- since the phone is on nougat or do I use Odin3_v3.13.1_3B_PatcheD for oreo?

2- Flash Non-carrier Unlocked Firmware -Oreo N950U1UEU3CRC1

Much thanks.
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
Since your firmware states you are on the v3 bootloader,

3

CRC1, defined by the 3. Download the latest Sprint firmware you can find at Updato, SamFirm, or Samsung Firmware Science, and flash it using the patched ODIN you mentioned. DO NOT use the HOME_CSC! The HOME_CSC will cause the conversion to not fully convert, which will leave you with way more issues than you ever want to try and troubleshoot and reflash as a result. Use the OYN CSC, which will wipe your device. Make sure USB Debugging in Developer Options is enabled and that you use the USB cable that came with your device. Do not launch ODIN until the device is already in Download Mode, connected to your PC, and you verify the drivers are installed in Device Manager.
[Samsung Galaxy Note 8 Guides, News, & Discussion] fbweip:
Hey, thanks for reply.

How do I find out what firmware I am on?

N950U1UEU3CRC1 <-I got this from the OP, under "ODIN FILES TO FLASH (Unlocked Non-Carrier Firmware): Unlocked XAA"

P.S. Would flashing Sprint firmware, cause phone to lose factory unlock? I want the phone to be able to change carriers in case my mother doesn't like sprint.

Because a few months ago, I searched for information to flash unlocked firmware to my sprint unlocked s7 edge and found out that the sprint bootloader version is too high so it cannot flash unlocked firmware. Not sure if this is the same with note 8.
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
If you go to Settings, About Phone, Software Information, and look at the Build Number and the Service Provider Software Version.

Those are the firmware and carrier information your device currently has. That firmware makes a big difference in what you should should flash, so determining that might change the steps you need to take. If you are on a TMB U, then you need to flash to a U1 first with the same bootloader or newer than your device currently has. From that point, you would then need to flash from the U1 to the Sprint U firmware. You should never flash directly from one U firmware to another U firmware from a different carrier.
[Samsung Galaxy Note 8 Guides, News, & Discussion] fbweip:
Build number NMF26X.N950USQU2BQLA

Service provider SW version SAOMC_SM-950U_OYN_XAA_0003ce081718f3349b2f027eXAA/XAA/XAA

I assume it is V2 bootloader. Also Tmobile firmware, not sure why maybe because the first service was Tmobile?

Steps:

1. Odin3_v3.13.1_3B_PatcheD, platform-tools_r28.0.1-windows, samsung usb drivers

2. Follow instructions on Post #4 + your previous reply to flash to U1.

3. You mention I need to flash -> U1 (N950U1UEU3CRC1_N950U1OYM3CRC1_XAA) then -> Sprint U (N950U1UEU1AQH9/AQI5/BQK1/BQL2/BRA5), correct?

Can I only flash to U1 to use on Sprint? Or do I HAVE to flash next to Sprint U? (My mother only need to make calls and use internet, does not need wifi calling/volte)

Thanks
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
Your device has the v2 bootloader, so the v3 firmware you downloaded will work fine. You can stay on the U1 firmware, but you might be missing some pf Sprint's carrier specific features. However, the U1 firmware adapts quite well but lacks VoLTE, WiFi Calling, and other features for most carriers. If you don't care about those features, flashing to the U1 non-carrier specific firmware and sticking with it isn't a bad thing.

XAA/XAA/XAA usually is all U1 non-carrier and setup without the SIM in the device. The first two should switch based on the carriers SIM you have in the device. Because this doesn't seem to have happened, I would suggest flashing the U1 firmware with your Sprint SIM in the device. After flashing and setting up the device again, you should see XAS/XAS/XAA. The first two should always adapt to the SIM in the device where the last one will not change.

SIM lock is independent of the firmware you can flash. If you flash a Sprint Note 8 to the Xfinity firmware, it will still be locked to Sprint. You need to contact Sprint or use an unlocking service to remove the SIM lock from your device.

The conversion is very straight firward. You will get the Xfinity boot animation, all of the bloat, bands, etc. The hardware for all North American Note 8's are the same. The only difference is the firmware that comes pre-installed on them.

[Samsung Galaxy Note 8 Guides, News, & Discussion] fbweip:
Hey,

Unfortunately, it seems the phone had a bad battery. So I exchanged it.

However, this one has baseband N950U1UESCRG9 and android 8.0.0.

I believe it is Tmobile unlocked firmware.

I realized the previous procedure did not work because this is v5 bootloader while the unlocked carrier firmware is v3 bootloader.

So I downloaded carrier unlocked firmware that is v5 as well. N950U1UEU5CRK1_N950U1OYM5CRK1_XAA

My intention is flashing the current XAA tmobile unlocked phone to carrier unlocked firmware. (I will be using on sprint but do not want sprint firmware).

But I am getting a fail result from odin3 patched.

This is the screenshot [IMG="Fail result"]https://imgur.com/a/70RRnV0[/IMG] https://imgur.com/a/70RRnV0

It says "Complete(Write) operation failed.
