[Samsung Galaxy Note 8 Questions and Answers] Comp1demon:
SO I picked up a 256GB emperor edition from Korea. It is Confirmed to have every single LTE band that AT&T uses. I put my sim in and only get 3G not 4G. Called at&t and they said they need to re-appropriate the IMEI for the USA as it comes up as a 2g/3g phone because the SKoren SK telecom IMEI assigned to the phone is different in the USA. IS that True? Anyone know how and if I can get the Phone to work on 4G LTE on at&t or do I have to hope they get it right? I paid $1400 for this phone I don't want to use a 64GB version I have been waiting to have 500+ GB on a phone for so long.. Any TIps? Hints? Recommendations?

EDIT: for those reading this thread for the first time. As of 10/9/17 I was able to get good LTE speeds as well as WIFI calling and Video Calling on my N950N note 8 Korean Exynos model. In a nutshell here is what I did to make it work.

Flash nemesis n950F rom to my phone.

Flash AT&T CSC to the phone using the CSC tool and you do have to modify one line (user RED FLAME) has this in the CSC thread.

Call at&t and give them the IMEI of a VOLTE wifi calling/video calling capable cellphone (I used my wifes S8+ - and yes you can DOUBLE USE IMEI on the same account)

I also did one other thing - Check page 14 for that information.

I just wanted to give a synopsis of this thread so new N950N and at&t owners don't feel like they are wasting their time searching XDA and google. I only wish other people did this when their problem is solved so people can easily see they are not in the wrong place and don't have to read tons of pages of stuff.
[Samsung Galaxy Note 8 Questions and Answers] LouK:
Hi.

There is a thread somewhere here they were talking about similar problems.

What you where told is essentially correct. Though they also said that they needed a new sim card, too.

Hope this helps. Still waiting for my Note 8.

Too bad those devices do not have the CDMA bands...

I have the same model and same problem but with softbank, though softbank has been less helpful.. i read someone flashing a different csc (if its the right one) will "unblock" the phone? Would any exymos model csc work?

My roaming menu is also greyed out... not sure if that is related.
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
I think you just need to give them the IMEI and have them set it up for LTE in their system, since they don't by default allow LTE on bring your own devices.

Did you change the apn? I have the same phone on tmobile and i changed the apn to the tmobile apn and i have no problems with the phone.
[Samsung Galaxy Note 8 Questions and Answers] Geekser:
Just a quick comment - I think you mis-spoke. ATT Does allow LTE on Bring your own devices. I have been using G955F variants for the last 4 years and never had to do anything other than put the SIM card in for it to work. HOwever, LTE Enhanced Services are not available on Bring your own Devices. This includes HD Calling, Wifi Calling and Video Calling. BUT, LTE will work.

I don't know anything about the Korean Model so I hope the OP is able to get things straightened out - but other variants have always worked on ATT - including TMOBILE PHONES and international variants as well.
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
That's probably what I meant. I haven't been an AT&T customer for many years, and have been with T-mobile for all my smart phone career, and they don't require any special setup on their end for VoLTE, Wi-Fi calling, etc as I can confirm with my Korean Note 8. After somewhat jankily switching CSCs with a modified script that was originally made for S8 and 8+ phones I definitely have VoLTE and probably have Wi-Fi calling working without any communication to T-mobile.
[Samsung Galaxy Note 8 Questions and Answers] Comp1demon:
Waiting on at&t now.. to see what happens.. SPEC for SPEC this phone is exactly the same as an at&t phone. It has every single band, not missing a single one. If you put the specs side by side there is ZERO difference. I changed the APN - there are 3 at&t choices. One gives me 3G the other 2 do not work. SO waiting on at&t to re-appropriate the IMEI to register as a note 8 on their network. I had not idea it was going to be this much of a pain in the arse. I was told by a few sellers, pop in your sim and your good to go. I did need a new sim since my note 4 sim did not fit in the note 8, so They gave me a new sim. I put the sim (using an adapter) back into my Note 4 until they change over the IMEI and the new sim works just fine on the note 4 - all my video calling, wifi calling and tethering work fine. So hoping I do not need to return this phone and use a 64GB model. I wish samsung would just release the 256 here on at&t like apple is doing with the iphone X. I would pay $1200 for it no problem. (and since the iphone X is $1149 with 256gb - I am sure samsung would do $999 or $1099 to undercut apple. But Samsung is going to epic fail and never give the US customers what they want.
[Samsung Galaxy Note 8 Questions and Answers] LostinCanada:
Hi there, I would also like to have the Emperor's edition, and use it in Canada (Bell) and USA (T-Mobile or AT&T). Is N950N the correct model number for this edition? Does it come with dual sim? Thanks! So far I found an Ebay seller from Hong Kong with F950FD which looks to be 256GB Duos - I'm wondering what the difference is with N950N and whether I will have an issue with region lock?

Thanks for any comments...

[Samsung Galaxy Note 8 Questions and Answers] Comp1demon:
Totally DIsappointed... No way I am keeping this $1300 phone for how crappy it is on At&T.

They Finally Updated the IMEI so that is shows up as a next gen smartphone on at&t network and I get an LTE logo. I set my own ACCESS POINT as well as used all 3 that showed up automatically. ATT Phone, ATT NEXTGENPHONE and ATT UTDATA (Nextgen) + I did what was recommended on att.com for bringing over a phone that might not get the access point which was the same settings as ATT Phone - all of them gave me LTE on my bar and showed AT&T as the network. Every single LTE Band on this phone is the same as the official ATT note 8. Yet on my speed test I couldn't get better than 4MB/s down and 1.56MB/s up, my note 4 (pop the sim card back in there) even with 1 Bar on my phone I get 42MB/s download and like 10MB/s Upload.

IT is too late to call at&t tonight but I am extremely disappointed. I have wanted a phone with 256GB of memory for like 2 years now, and to have MicroSD expansion for just MUSIC (NOTHING ELSE).

If At&t can't get this note 8 to perform exactly like a at&t version would, then I either going back to my Note 4 or Perhaps the US Samsung unlocked version (which I already have but is not opened as I hoped to sell it and make a few hundred on it to make up for the $1300 I spent on this Emperor Edition.

Any advice?

Anyone want to buy it.. I paid $1299.99 Shipped from NK. Instead of returning it - if anyone wants to buy it, id do the same thing $1299.99 shipped anywhere in US or Canada. Perhaps it will work better on another network...

Does your unlocked version work as it should.. FAST LTE 4G LTE? Does your WIFI and Video Calling work?

Have you Odin the CSC and IMS? From what I have read that needs to be done?
[Samsung Galaxy Note 8 Questions and Answers] jocarog:
No, I haven't flashed the CSC profile, no wifi calling or VOLTE but internet speed is fast...
[Samsung Galaxy Note 8 Questions and Answers] d.cortez:
tl;dr - Under Settings->Connections->More Settings there's an option titled Reset Network Settings and, i had to use that on my Korean, Note Fan Edition to get LTE working.

more detail on how i got VoLTE and HD Voice working.... i grabbed an ATT (Snapdragon) S8+ CSC and manually applied to the FE. To get HDVoice and VoLTE working, i called ATT and told them i was going to use my (no-longer used/retired) ATT Samsung S7Active with my cell number. this step was a must to get VoLTE working. once they associated S7Active IMEI with my cell number, i rebooted the Note FE and VoLTE was active. i occasionally receive calls and the HD Voice icon appears on the dialer screen; i assume the other person is calling me via Wifi when i see the icon. Video calling and Wifi calling haven't worked for me on none of my international devices. once i got my UK note 8, i applied the same CSC content (after rooting my device), i inserted the same ATT sim used in the Note FE, reset network settings and VoLTE and HD Voice (when receiving calls) still works.
[Samsung Galaxy Note 8 Questions and Answers] Flame Red:
I don't know about the Korean model, but here is how you get Volte on ATT on the Note 8 F model. https://xdaforums.com/showpost.php?p=73851525&postcount=308 After you slightly modify the zip and flash this, you must call ATT and give the friendly customer service person the IMEI of a phone purchased from ATT directly that is roughly equivalent and had Volte and wifi calling features. I used an old S7. ATT will NOT accept an IMEI of any phone not sold by ATT. Once they put it into their system, reboot your Note 8 and whala - wifi calling and Volte work perfectly.
[Samsung Galaxy Note 8 Questions and Answers] Comp1demon:
Kind of a NOOB when it comes to all this. I haven't flashed or done any phone hacking in a few years (my s4 was the last phone I really played with).

SO I downloaded the CSC Selection V1.2.1 on Android Filehost

I honestly do not know what to do from here.

Thanks.
[Samsung Galaxy Note 8 Questions and Answers] d.cortez:
did you try resetting network settings to at least get LTE going? Under Settings->Connections->More Settings there's an option titled Reset Network Settings and, i had to use that on my Korean, Note Fan Edition to get LTE working. Or are you good to go on LTE?

Is Nemesis still the ROM to flash for AT&T on N950N?

"Flash nemesis n950F rom to my phone.

My Korean N950N arrives soon and I wanted to check and see if Nemesis ([ROM][7.1.1][AQI1][16/09]NEMESIS NOUGAT N8 V2.0) is still the best ROM to get good LTE speed with AT&T. I've been searching and reading XDA for hours and I can't find other wise but wanted to ask someone running a N950N on AT&T

Thanks for any help or opinions

I dont think that option is available on the korean n8 (i have the kt carrier version and its not showing up (not even greyed out) i get a "needs activation" prompt which im assuming is that whole make a call in korea for 10 minutes business, not likely to heppen soon.. but if there is an "unblocked" CSC we can use then at least there would be a solution that doesnt trip knox or require root (I think).

[Samsung Galaxy Note 8 Questions and Answers] XATAGuy:
I can't get LTE working on my N950F/DS purchased from Singapore. I've been to my local (Non-AT&T owned) store and spent time today on the phone with telephone support. I got LTE on my old Elite X3. When I put my AT&T sim into my note from my Elite X3, I only got 4G. Both the store and telephone support were able to make it worse (2G), but I have yet to see LTE on the Note. We have installed a new sim, and they assigned a generic IMEI. No joy. Don't know what to do. Any help would be appreciated. Thanks!

Yup. Sure enough. Thank you! I would never have looked there!

So, I did this reset. No help. I'm determined to get LTE on this phone. I know there is at least one guy getting it with T-mobile. I'm AT&T and really don't want to switch, but I will if I have to. Will spend some more time on the phone today with AT&T trying to escalate my issue.

It looks like I will very soon be to the point of flashing CSC. Have never done this, and don't know how.....

[Samsung Galaxy Note 8 Questions and Answers] XATAGuy:
Thank you very much for this. Very helpful. I have configured mine exactly like yours (Only changes were Authentication to "none" from "not set", and APN type) and still only getting 4G. No LTE. Will get back on phone with AT&T. May I ask your model number and country of purchase? Thank you!
[Samsung Galaxy Note 8 Questions and Answers] MeltdownSpectre:
FYI, 4G on International model phones means LTE. The actual logo displayed in the status bar is CSC dependent.

Enable the data connection on your phone, open the dialer and dial *#0011#, if it's a Dual SIM device, select 'STACK 1' on the screen and post a screenshot here, if it's a Single SIM device, dialing the code above should take you directly to ServiceMode where you can take a screenshot and post it here so I can confirm for you whether or not you're actually on LTE.
[Samsung Galaxy Note 8 Questions and Answers] XATAGuy:
Thank you!
[Samsung Galaxy Note 8 Questions and Answers] MeltdownSpectre:
Yeah you're on LTE, it just says 4G cause it's the International variant and doesn't have the carrier icons that come with the AT&T CSC.

The screenshot shows you're using Band 2 (1900 MHz) LTE on AT&Ts network.

Just note the following:

2G (dunno if AT&T still has its 2G network) will show the 'E' icon in the status bar

3G will show either 'H' or 'H+' for HSPA+

-> HSPA+ was marketed as 4G in the USA, hence the confusion when some people think the 4G icon doesn't actually mean 4G.

LTE will show '4G' or '4G+' in the status bar.

TL;DR There's nothing wrong with your phone and it'll work just fine on AT&Ts LTE network.
[Samsung Galaxy Note 8 Questions and Answers] XATAGuy:
Fantastic! Thanks a million for your help!

Sorry been sick or I would have responded faster.

I do not have that option under MORE CONNECTIONS.

I just popped my sim card back into the SK telecom NOTE 8 and I am going to try it out in the field tonight. See if anything has changed.

Do you get a 4g LTE Icon like on an official ATT phone on your korean phone or you just get LTE icon?
[Samsung Galaxy Note 8 Questions and Answers] 52yt:
I think you can flash a rom to make it international model( N950F), and it works on my N950N, so just let you know that is the simeplest way to solve this problem. Now there are not many options but you can still find two roms in orginal development and after flashing the rom, my att sim card works as 4G now.
[Samsung Galaxy Note 8 Questions and Answers] peacey8:
XATAGuy, I also have the N950N model but I'm using it in Canada (on the Bell network). When I first got the phone it was on the SKC CSC (Korean carrier) and I only was able to connect to 4G networks. I only saw the 4G icon in the status bar. Also I ran a speed test and only got 10 Mbps download so I was sure I wasn't connected to LTE. I then changed my CSC to the Canadian one (XAC) by flashing a CSC changer zip in TWRP. I then had the LTE+ icon and when I did a speed test I got 100 Mbps download so I knew I was definitely connected to LTE.

Not sure how it is for AT&T, but it is definitely possible to get the LTE icon on this Korean model for at least my network in Canada. Also, I suggest you do a speed test to see if you're connected to 4G or LTE. I'm not sure what LTE speeds are in your area but it would be easy to find out if you had another LTE phone. Theoretically they should be similar to mine unless you live in a bad service area.

You will lose your warranty, but I think it may not matter in general since obviously you don't get the phone from a carrier or samsung.

I would get the version for the carrier you are using. You probably arent going to need 256 internal storage anyway. The sd slot supports all that extra space. Itll save you trouble and be cheaper
[Samsung Galaxy Note 8 Questions and Answers] Comp1demon:
and this is the problem... People telling me what I need or do not need in storage.

I NEED the 256 + the Micro SD slot... I have been wanting 128 or 256 + SD for 2 years now. I refuse to go to apple. This was the only option. I will be very sad to not be able to get this to work right.

I am reading about TWRP and what to do next. I will update once I get it done.
[Samsung Galaxy Note 8 Questions and Answers] arange:
There are people who use more than 256 gb of storage. Also as for me, therr is no version for my region so i can only get one out of region. Finlly the internal storage is much faster than most (any available?) sd cards, so having 256 of super fast internal storage is also a boon.
[Samsung Galaxy Note 8 Questions and Answers] taubmax:
I just really need some straighforward instructions in APN settings for AT&T with the 256GB Korean model. I love the Blue color and don't want to have to return this! I know nothing about flashing. The only way I get mobile data is by setting it to APN ATT Phone and all I get is 3G. AT&T tech support is useless. Please help. Thanks all! And sorry this thread is out of order...
[Samsung Galaxy Note 8 Questions and Answers] 52yt:
Unfortunately, the only way to fix it is to flash something, either a ROM or CSC files or other things. I don't think changing APN settings would help you. You can always ask ATT for higher tech support but I don't think that would work well. So if you decide not to root and flash roms, there is nothing I can do with it.

I am the Guinea Pig trying to get this done for AT&T as I have N950N as well and want to use it on at&t. 52YT has been helpful, but I will agree with the poster above, noobs like me sometimes need more than just advice, straight up Step by Steps might be helpful.

I downloaded the Nemesis rom 52YT recommended.

But in order to flash it using TWRP you need to install it.

I am on the TWRP for EXYNOS forum now trying to get it installed.

Nothing so far.

Downloaded Odin 3.12

Downloaded the recommended Tar file from the first post of this thread. (https://xdaforums.com/galaxy-note-8/development/recovery-twrp-galaxy-note-8-exynos-t3674036)

OPened oden.

Turned on phone POWER+BIXBY+DOWN

GOt to a Korean DOwnload mode (no english).

PRessed UP and am now in download mode.

COnnected to PC and let Drivers Install.

Loaded the .tar file for TWRP into the AP box of ODIN and II get a MD5 error and Can not get any further.

So as of right now. I can not flash the nemesis Note 8 debloated ROM as 52YT recommended to get VOLTE and Proper LTE 4G working on my Note 8 with AT&T.

SO until I can get further. - I am just gonna be stuck until someone can be helpful beyond some "advice" that usually comes without explanation.
[Samsung Galaxy Note 8 Questions and Answers] 52yt:
OK, another thread

---------- Post added at 12:14 AM ---------- Previous post was at 12:13 AM ----------

I actually met the same problem. Is the downloaded file name "......tar.md5" like that? You need to delete ".md5" part and then you will be fine. I think the original developer mess up with the name of the file. That's all.
