Deleted the extension like you said. YES! Loaded into AP.

turn on note 8 in download mode.

Plug in phone

Press start on Odin NOTHING.......

Can't even get TWRP installed.

I feel like a failure.

EDIT: I unplugged the phone from my laptops 3.0 port and plugged it into a 2.0 port.

Loaded TWRP into AP and Flashed.

I got a PASS!!

Phone Rebooted back to main screen.

Turned it off...

BOoted with UP+power+BIXBY - all i get is the regular black menu with Reboot system now down to power off - no TWRP..

NO idea what is going on..

Help anyone?

OK EDIT AGAIN: GOT IT!!!

You have to hold UP+BIXBY+POWER then press start on ODIN and it flashed - reboots and boots into ODIN.

OK so now I am ready to flash the N950F Nemesis rom. see if that give me VOLET 4G LTE for my at&t Service

Help please
[Samsung Galaxy Note 8 Questions and Answers] Comp1demon:
Whole new post...

52YT - thanks for the help so far.

TWRP install - got it all figured out and easy to do now.

USing TWRP and installing the Custom Rom you recommend. - A bit harder. DId a few things wrong, but I took the initiative to really figure out what went wrong.

Got it installed and booted.

Results........... Worse the the N950N rom from SK telecom. I got 3MB/s with that on speed test now I barely get 1MB/s.

SO asking.. do I need to flash CSC too???

IF so - I read all about it and I am utterly confused.

If someone could lay it out for me please on what to do, what to download.

Please let me know.

Thanks
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
I think there are some settings not enabled in that Nemesis ROM because my LTE signal and speeds are about 1/2 to 1/4 what they were with the SK Telecom software.
[Samsung Galaxy Note 8 Questions and Answers] Comp1demon:
Exactly what happened to me.

There is a User RED FLAME who is on att with Note 8 (n950n) and he claims to have it working. I will report back if he gets back to me.

He manually edited a CSC file and flashed it. I am having a hard time understanding the post and trying to figure out what he did.
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
Well I flashed back to stock, added the Notorious kernel and my CSC patch again but my mobile signal still sucks. I'm going to temporarily reflash to stock again and see if the kernel or CSC are to blame.

I can report that being on a stock 950N base made Carrier Aggregation work again in the menus.

I have a N950F, not a N model. If I posted the wrong model number by accident, my apologies. Got it from Clove in the UK. F model works prefect on T with Volte too.

I read your post and I am slightly confused becuase you manually edited something, I barely got through flashing and such so was hoping you could help out by dropping a link for the CSC you flashed already edited. Also if you do not mind throwing up a few hints (tips) on how to flash that would be great. WOuld really appreciate it.
[Samsung Galaxy Note 8 Questions and Answers] Flame Red:
Ok, I try to highlight what I did on my Clove N950F.

Install TWRP, using the procedure here: https://xdaforums.com/galaxy-note-8/development/recovery-twrp-galaxy-note-8-exynos-t3674036

You can now either root your phone using Magisk or SuperSU, or you can install your favorite ROM, or stick with the OEM rom. I installed the RENOVATE ROM, procedure here: https://xdaforums.com/galaxy-s8/samsung-galaxy-s8--s8-cross-device-development/g95xf-fd-n-renovate-ice-note-8-port-t3674154

Fetch Flashable CSC Selection V1.2.1 from Tkkg1994, from here: https://xdaforums.com/galaxy-s8/samsung-galaxy-s8--s8-cross-device-development/utility-flashable-csc-selection-v1-1-0-t3636739

Assuming your CSC is in his fine tool, you need to open his zip file, and modify it. Please note, although this worked for me and others, some people have reported that other carriers did not work using this method. Check the above thread first. Tkkg1994 reports that the Note 8 CSC files are indeed different and he will not support the Note 8.

I did this on a PC, but you can use a similar procedure on your phone. I opened the Tkkg1994 zip file using 7-zip and modified META-INF/com/google/android/updater-script using Notepad. It is a bit tricky. I added this:

getprop("ro.product.device") == "greatlte" || getprop("ro.build.product") == "greatlte" || getprop("ro.product.name") == "greatlte" ||

Save the file, and rezip it and copy it to the phone via USB.

Boot into recovery and flash the CSC tool you just modified. If you get an error, then you screwed up the editing. It will flash if you edit it correctly. Actually, I had to try editing it a few times as I think garbage characters were added. I did not want to break any XDA rules and post my own copy of Tkkg1994 tool without his permission. I think another user on the above thread may have edited it and posted his modified version in the thread in the above link. That is not mine. YRMV.

Call the carrier. In the case of ATT, you need to give them the IMEI of a real phone purchased from ATT that supports Volte and WiFi calling. I gave them an IMEI of a S7 bought from T we had active on the account. They did not seem to care that the IMEI was duplicated on two different lines. All they cared about was the IMEI was from a phone bought from ATT. If you give them your real IMEI of an International phone their system will not recognize it and they will not enter it and Volte won't work. Other carrier seem to be different.

Reboot as directed by your carrier.

You will then see Enhanced LTE Services, and WiFi calling stuff appear in Settings ==> Connections and those services then did work on the N950F, at least for me.
[Samsung Galaxy Note 8 Questions and Answers] dec3169:
Would this work?

I'm in the same boat - Korean 256gb 950N (now 950F after rom flash). I'm upgrading from a Note 4 to the Note 8 (sidetrack - was it really necessary to have different sized SIM cards?).

I went to an AT&T store (retailer not corporate) and they tried to activate my 8. It worked for 1 minute but then the sim reset and I lost connectivity. They tried for 1.5 hours to get the 8 back and finally the 4, and it was dumb luck they got the 4 running again. I am not going back there...

What if I used one of those IMEI changers and changed my 8's IMEI to the one from my 4? AT&T left the nano sim in my 8, and it wants to activate in the AT&T phone app. I've not changed a sim before but I believe there is a program that can set the sim ID to whatever.

Could I just set the nano sim to have the same ID as my old note 4 sim and change my IMEI to my old one, and not even have to deal with AT&T?

I haven't tried the TWRP CSC thing because I have to get a good backup with Titanium first, but I may look at that this weekend too.
[Samsung Galaxy Note 8 Questions and Answers] Comp1demon:
OK so everything 52TY suggested I have done.

TWRP Installed

Nemesis rom - installed

CSC - ATT installed and thanks to Flame red for walking me through that change to that one file. I was able to get it done thank you.

So result.... SO FAR - best lte speed is 4MBs Put the sim back in my note 4 and I get 20-30MBs and I have only 1 bar in my home. If I get 2 bars I get about 40MBs - the note 8, 2-3 bars and I get 4MBs max.. So disappointing. I really hate to get rid of this phone. I really want that 256 Nand memory on the phone. I am really pissed that Samsung would not offer this variant in the USA, it is ultra disappointing. I spent $400 more than every other att customer and for 2 weeks now I have sat here at my computer on this forum trying to get my phone to work.

RED FLAME recommends a different rom. I might try that too. Flashing them seems easy enough.

DO I have to reflash the CSC after flashing the ROM?

Should SIM be in during flash or does it not matter becuae I rather have a working cellphone (note 4) while working on my note 8.

IF I can get my Note 8 to get 40+MBs with LTE I would be so happy.

I have the VOLTE and Att 4G icons showing up after flashing the CSC from the RED FLAME recommendation.

I will keep all updated.

Any other hints, tips, trick - welcome.

ANY other 256GB note 8 users on ATT get this working yet?
[Samsung Galaxy Note 8 Questions and Answers] Comp1demon:
OK so I did everything you said SORT OF.

I will cover it all....

TWRP installed - no issues

DID NOT ROOT PHONE - I want to be able to use samsung pay and other apps that root breaks.

Downloaded Renovate and Installed!! - Install went fine got LTE after install and about 4MBs

As per our PM conversations I installed CSC as you told me to..

Selected ATT from CSC tool.

NOw here comes the part I did not do... CALL ATT and give them IMEI of real purchased phone. I have an at&t purchased NOTE 4 that they have the IMEI for and I have been using for 3 years. It supports (Volte and WiFi calling) as I was using them on my NOTE 4 with no issues. So I assume taking the SIM out of it and putting it in my note 8 will work just fine. SO I did.. I set up the phone and I even setup WIFI calling and Video Calling and WIFI calling registered and since it is 1am and I cannot call my wife and wake her up to try video calling, I just put in her phone number and the Video calling link went from grayed out to Green so I will assume it works too. If the WIFI calling registered, Video calling should work, I will check for sure in the morning. Going to assume the SIM from my NOTE 4 that they already have the IMEI for should be fine to put into my note 8. It seems to work, but the speeds still do not equal what I was getting on my note 4. I was getting 20-40 (depending on bars as my house sucks for bars) and the best I got so far with this ROM and CSC is 15MBs. I can live with it for now, just to try, but if I can not get it to match my wife's S8+ in speeds I plan on returning or selling this phone.

Not sure what you mean by REBOOT as per carrier.. I rebooted each time I did a step. Flash ROm, reboot, Flash CSC, reboot, Set up phone and such after putting SIM in, and Rebooted. Is there another setting you referring to? My access points only shows ONE ATT NEXTGEN PHONE, which is what my note 4 and my wife's S8+ use so I assume that is good to go.

Any other tips or tricks?

Anyone else want to weigh in?
[Samsung Galaxy Note 8 Questions and Answers] Flame Red:
I forget if a Note 4 uses a nano Sim or a Micro Sim. But if the Sim fits, insert it.

ATT has the IMEI of your Note 4. I believe, but I am not totally sure, that the Note 4 does or does not support Volte and WiFi calling or is just HD calling. You want an IMEI with the same modern feature set as the Note 8 does. If the Note 4 has modern Volte, you should be ok. If it does not, then you got to call ATT and give them a IMEI of a phone purchased from ATT that does support Volte and WiFi calling. I used a S7 we had on another number on the account purchased directly fron ATT.

And for the reboot, after ATT inputs the IMEI into their system, they ask you to wait on the call and then ask you to reboot your phone and they want to make sure Volte comes active.
[Samsung Galaxy Note 8 Questions and Answers] Comp1demon:
AHH i understand...

That kind of sucks then if my note 4 doesn't have the features of the Note 8 in terms of LTE..

So basicly I would have to buy a phone that has those features in order to then put the sim in my note 8.

I found a stop with full 5 bars and got about 25MB/s still not as good as my note 4 with 2 bars at 40MBs

I do know it supports WIFI calling and Video Calling becuase I had those features on my NOTE 4 since 6.1.1 got introduced via update about a year ago. I set up wifi calling. I am sure it is WIFI and NOT HD calling. The only thing I am not sure about is VOLTE. I know I have 4GLTE.

Kind of feel between a rock and hard place now.. becuase even after all the Flashing and getting the right CSC and such, I am going to get limited becuase my IMEI is from SK and does not show as a Note 8 on the at& t network nor is it an at&t phone.

Ugh....

off topic: [MENTION=4937195]Flame Red[/MENTION], used your guide to modify the zip file, flashed on my (Clove purchased) N950 and i successfully enabled WiFi calling. will test WiFi calling and Video Calling when i get home later today. thanks

NOTE: Confirmed WiFi calling works - put device in Airplane mode - made 2 calls, one using Google Voice and one with my regular cell # and both worked. call quality is significantly better when using regular cell # vs Google Voice. no luck with Video Call - still trying to get that to work.
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
Those of you who are experiencing terrible data rates after flashing - did you try going back to a basically stock full nandroid backup? After struggling with this all week I finally got fed up and flashed a nandroid backup from before I started monkeying around with everything and it appears to have restored my super fast and strong LTE. I had tried Odin'ing back to stock but that didn't help so my guess is something in the EFS partition became screwed up, and restoring a better backup solved the weak signal and data transfer issue.

Going to start over with my project to add T-Mobile Wifi Calling to single SIM N950N base, too many variables trying to use ROMs for the 950FD
[Samsung Galaxy Note 8 Questions and Answers] Comp1demon:
Took Flame Reds advice about the sim card.

My wife has an official at&t Galaxy S8+ . SO I took her sim card out of her phone and put it in mine.

I did not see any difference in speed really. Her phones sim should have all the features Flame Red talked about so her sim card should have made my note 8 work at it's peak if I have the ROm and CSC flashed correctly.

My signal sucks in my home.. so I am hoping to try this experiment again in a place where the speeds are good.

Last night I camped out for a SNES CLASSIC and had my ipad tethered to my Note 8 for netflix. Seemed to work just fine. As I said the spot I was in was 4-5 bars at all times so I got like 25MBs slightly faster.

I wonder if I went into an AT&T store if They could put my sim card in the demo unit and test the speeds on their at&t phone in the store and let me compare it to mine in the store.

That should give me the indication of if it is working right. I need to a new sim for my other number anyways as I am tired of using the S2 Gear watch. So I will see.

I will keep this thread going incase anyone else has questions or solutions for getting the N950N working perfectly on at&t.

I can say this. I tested Video calling and WIFI calling.. both work perfectly. So I know those features work.

I also did a Smart Switch finally from my note 4 over to my Note 8 and that went well too..

So I will try out the note 8 (this N950N SK telecom version) as my everyday phone now.

[Samsung Galaxy Note 8 Questions and Answers] Amnotabot:
The one from Hong Kong is different from the one you get in Korea. The one from Hong Kong uses the snapdragon processor and it supports CDMA. Also it's dual sim but it has the model number SM-N9500. Oh and make sure to tell the seller to region unlock it with a Hong Kong sim.

Is Hong Kong Snapdragon Version 256GB of internal storage?
[Samsung Galaxy Note 8 Questions and Answers] Amimnotabot:
There’s a 256GB model from Hong kong (SM-N9500) it supports CDMA, has a snapdragon processor, and it's dual sim. I saw a few listings on Ebay but I prefer the Korean one.
[Samsung Galaxy Note 8 Questions and Answers] Comp1demon:
Wondering if the HK one would be better on at& t since it has a snapdragon. WOndering if my poor LTE speeds are because of the exynos processor.
[Samsung Galaxy Note 8 Questions and Answers] Amimnotabot:
Did the seller insert a Korean sim for 5 minutes before shipping the phone? Was your phone factory sealed? Because it might have region locking because Samsung doesn't like importing their phones to other countries. If you still can return it, maybe return it back and then order one again (Snapdragon or the Korean one).
[Samsung Galaxy Note 8 Questions and Answers] Comp1demon:
The phone was Factory Sealed when I got it.

Should be region unlocked. My sim worked in it just fine when I got it, just did not get LTE speeds. But 3g was just fine and phone worked for calling with my sim.

I already flashed the TWRP, the N950F rom and an at&t CSC.

I probably could flash back the SK telecom CSC and stock rom and return it, but that would probably be a bit shady.

According to every website I read Everything is Band for Band with this phone except (1) band... I checked the Website that shows you all the carrier bands that the network uses and the n950N vs the N950U (which is what at&t sells) had everything except one band. I really hope that is not the one band in my area they use - if so that would suck.

There is no way I am going to a 64GB phone - Even with microSD I can't do it. I want 256GB resident to the phone without microsd installed.

I also noticed I can't use Samsung pay which sucks - even though I did not root the phone when flashing. From what I read I can use Magicsu and hide magicsu and use android pay, but was really hoping to use Samsung pay. So there is already a huge feature that sucks not to have after dropping $1300. My WIFI calling and Video calling work just fine.

So hoping that someone here works some magic down the line and makes this as compatible as possible with at&t.

I have read about S8 and S8+ users who have SKtelecom SK phones on at&t working fantastic 50-80Mbs on 4gLTE - so hoping my note 8 will get there.
[Samsung Galaxy Note 8 Questions and Answers] Kamikaze_Ice:
I've been following Kalm_Traveler's progress in his CSC threads. I have the same phone as him (N950N, Korean 256GB version), bought from the same ebay seller. His "mod" is for T-Mobile, but is easily edited for AT&T, which is my carrier.

However, AT&T is being an asshat. I can't get their "features" working properly at all.

In fact, my Note 8 has the same results at my HTC One (M8) which WAS bought from AT&T. Stock or custom roms, default vs other radios, nothing makes a difference and this is totally on AT&T's side and they are being very stubborn.

I've had this problem on at&t since subsidised phones stopped being a thing, and I wonder if it's related.

I happened to notice this while reviewing my plan history trying to track down when I had an erroneous $700 text messaging fee about 5 years ago.... on a device that had NO texting what so ever (I specifically requested it to be removed for a data only device for work purposes).

https://www.att.com/gen/public-affairs?pid=20879

Basically throttling happens when you've used 75% of a data plan now, and can fall as low as 128Kbps.

Unlimited Choice and Unlimited Plus plans get throttled after 22GB.

Furthermore, they have a table of their networks and expected speeds...

3G

Down = 3-7 Mbps

Up = 0.7-1 Mbps

4G

Down = 2-7 Mbps

Up = 0.4-1 Mbps

4G LTE

Down = 6-29 Mbps

Up = 2-11 Mbps

Also, and in my opinion, it looks like the "HD video streaming" feature is related to VoLTE/WiFi Calling somehow due to AT&T using a whitelist for provisioning to make it difficult to get on a non-AT&T device...

Well today I got my N920N 256gb version and so far everything:svetius: has been pretty smooth .At first the phone failed to get LTE would only get 3g but after about 20mins LTE kicked in and works flawlessly.Mind you I'm in a apartment so this is about my average but I will have to thoroughly test the device in other places.Btw I'm running Dr.Ketan's rom atm

Edit * I went for a drive to retest LTE seems like I get LTE but speeds are no higher than 25mbs and I know where I get high speeds I get 70 to 80 on average so yeah there's something fishy here
[Samsung Galaxy Note 8 Questions and Answers] Kamikaze_Ice:
Not that I can offer any advice, but is that with a new simcard, or previous device simcard? Was it "provisioned" for these things (working on previous device with same simcard, or had at&t rep manually provision it via phone/store/chat?).
[Samsung Galaxy Note 8 Questions and Answers] MeltdownSpectre:
The fishy part is that the US variants have carrier aggregation combos in the same bands used by US carriers.

So suppose AT&T is using Carrier aggregation of Band 2 and Band 5, your phone would be using both those LTE bands simultaneously, however being an N950N variant, it may not support the same carrier aggregation combos used by US carriers since it's not a US phone.

This is why it shows '4G' on the status bar. 4G indicates it's only using LTE through one band, if the icon changes to '4G+' that means it's using 2 or more bands in a carrier aggregation setup for LTE.

There may be a way to get it to work, which is by flashing the ATT CSC, setting up all AT&T features and giving them your IMEI to provision your device to take full advantage of their network, and then restarting your phone.

If 4G+ still doesn't work, it's probably because the phone doesn't support those particular band combinations and you'll be stuck with single band LTE.

Sent from my SM-N950F
[Samsung Galaxy Note 8 Questions and Answers] Kamikaze_Ice:
If a radio band is supported, I would assume any combination of all supported bands to not be an issue. Otherwise I don't see how anyone could consider it "supported".

https://www.frequencycheck.com/mode...50n-galaxy-note-8-td-lte-256gb-samsung-baikal

That site says the only one AT&T band is not supported, 30, which should only be an issue if you live in a highly congested area that has it deployed (the "big" cities).
