In china it won't work properly with telecom but you can use china mobile or china unicom.

I am using china unicom on oreo and its working awesome.

---------- Post added at 11:54 PM ---------- Previous post was at 11:49 PM ----------

Just do a factory reset by booting into recovery and it will be done.

I am in china i updated to oreo nd using china unicom with LTE.

Check out the link for bands supported by N950U1 of china telecom.

"Just do a factory reset by booting into recovery and it will be done."

Ive done this, but to no avail. It just sits at the phone activation screen until it says it couldnt be done.

I had a quick question. My unlocked note 8 now gets crap signal with oreo on tmobile. Can i flash the U firmware on a U1 to see if it'll help?

---------- Post added at 01:26 AM ---------- Previous post was at 12:34 AM ----------

Actually.... is it possible to flash the 7.1.1 radio to the oreo build?
[Samsung Galaxy Note 8 Guides, News, & Discussion] Stevieboy02008:
Yes you can.

Although I would suggest doing the carrier switch first then flash it.

I had that issue with my unlocked till I actually did the carrier switch to the unlocked then flashed it and no issues at all
[Samsung Galaxy Note 8 Guides, News, & Discussion] re1ic:
I did that. It didn't help the signal so I thought I'd try going with the U next. If it doesn't fix it then I'm going back to 7.1.1 until I can figure out how to port the old baseband radio to Oreo.
[Samsung Galaxy Note 8 Guides, News, & Discussion] Stevieboy02008:
That should work.

Have you tried flashing only the Usersata
[Samsung Galaxy Note 8 Guides, News, & Discussion] re1ic:
Yeah, I had the same problem with my international verison note 8 so I switched it out with the US version. My sons s8+ now has no signal either where we had full bars. I'm going to try to just flash the CP from the 7.1.1 software and see if that doesn't help. If so I'll flash his and try and figure out what to do about my wifes s9+. She may just have to wait for an update. I can't go with spotty signal with my job, and this new update has made what used to be great signal to where we can't get msgs or calls at home.
[Samsung Galaxy Note 8 Guides, News, & Discussion] Stevieboy02008:
I understand. Let me know if you need any help my man
[Samsung Galaxy Note 8 Guides, News, & Discussion] arpitarora55:
Can you please clarify which kind of phone activation is it demanding? And in which countrybare you doing? By the kind of activation i mean that is it google activation or demanding some normal activation or what? Send the screenshot if you can?
[Samsung Galaxy Note 8 Guides, News, & Discussion] andyli83:
Right out of the box from verizon, it was working fine on China Telecomm (voice and 3G, but no 4G). As far as I understand, the phone hardware supports China Telecomm, but once the Verizon firmware gets loaded after starting up, it blocks out 4g and only allows 3g. However, after updating to Oreo 8.0, now there is no service at all (no voice, 3g, or 4g, nothing at all). Also, after updating to Oreo, when I restarted the phone, on the initial security log in screen (where it asks for my pin number), the Samsung keyboard keeps failing to load, so that I can't continue to start the phone. Any ideas?

---------- Post added at 04:26 AM ---------- Previous post was at 04:20 AM ----------

I did a search for China Telecomm APN and entered it in manually, but still got no service. I am wondering if flashing the verizon firmware with the U.S. unlocked version will resolve this problem.
[Samsung Galaxy Note 8 Guides, News, & Discussion] arpitarora55:
:eek:By not working properly i meant the same u said about china telecom. just flash the unlocked oreo CRC1 on ur N950U and try making it work. Also i hope if u flashed the firmware in china and have not removed the google and samsung accounts there will be a frp lock which u cant bypass without vpn router or complex methods.

If u can check the frequency supported by american note 8 u will get to know that China Telecom's Frequency (Like many bands for 3g or 4g are not supported). I would suggest you to install CRC1 oreo U1 on ur note 8 and try telecom on it. Other wise use china mobile or China unicom.

Verizon Note 8 flashing

Hey Guys, I have a Verizon note 8 I flashed a while back to the unlocked firmware. It is on oreo unlocked firmware now. I'm trying to get it back to stock Verizon firmware to sell the phone. I have downloaded the oreo verizon firmware and used the newest odin 3.13 filled in bl, ap, cs, cvc and userdate it just keeps telling me "all threads completed (succeed 0/ Failed 1 ). What am i doing wrong? Thanks in advanced
[Samsung Galaxy Note 8 Guides, News, & Discussion] BlueFox721:
Are you using the patched Odin or regular....typically you need to use regular....but if you have changed code to XAA you may need to use the patched version
[Samsung Galaxy Note 8 Guides, News, & Discussion] alrightythen:
I have used both regular Odin (newest) and the patched Odin (newest) for Oreo with the same result.

If I flash the carrier unlocked version of AT&T Oreo, will it load their version of mobile hotspot enabling where it requires registering through their website first, or will it have native unlocked mobile hotspot that I can just enable and use?
[Samsung Galaxy Note 8 Guides, News, & Discussion] Stevieboy02008:
It does have the native WiFi hotspot
[Samsung Galaxy Note 8 Guides, News, & Discussion] illusivenick:
Like Stevieboy02008 said - It does have hotspot. But I suggest flashing att CSC and Modem so that you get better reception and VoLTE. You'll still have hotspot with this setup...
[Samsung Galaxy Note 8 Guides, News, & Discussion] ravx25:
I'm not on AT&T though, so I don't need VoLTE. I'm on cricket. My single biggest issue with this AT&T Note 8 phone is they have the mobile hotspot locked down to them only, so if you unlock the phone and go somewhere else, you can't use mobile hotspot.

It sounds like I'll have to use the XAA firmware and flassh the AT&T modem. What is CSC for? Since I don' use VoLTE or WiFi calling I'm not concerned with those features. I just want to make sure I don't have that nasty locked down mobile hotspot and I have a good signal, otherwise, I have no issues with this AT&T phone.

I don't think that you can flash Exynos to Snapdragon my man.

Unlocked XAA

*Any carrier can flash this version because your SIM and device CSC code will setup proper carrier info, but you can look below for the specific carrier branded version if you choose*

Oreo

N950U1UEU3CRC1

am i stuck on oreo if I flash this or can I go back? also is this one the mostly bloat free one? thanks!
[Samsung Galaxy Note 8 Guides, News, & Discussion] BlueFox721:
You can go back as long as you do not upgrade to bootloader V4
[Samsung Galaxy Note 8 Guides, News, & Discussion] BlueFox721:
You can flash unlocked XAA firmware but can't guarantee that connectivity will improve...

So i have an originally Verizon Note 8 N950U, I changed my cell phone plan over to ATT. I'm trying to get VoLTE and potentially Wifi Calling to work, so I flashed full ATT Oreo firmware. I'm now thinking that I should have done a carrier switch first. Should I downgrade to the latest eligible (BRA5 for Verizon) firmware that my phone is intended to be, perform the change carriers part of the guide, then flash the ATT firmware? Thanks
[Samsung Galaxy Note 8 Guides, News, & Discussion] BlueFox721:

I currently own a Sprint Branded Note 8 SM-950U it has been UCIC unlocked. The phone has been OTA upgraded to Oreo N950USQU3CRC2 Sprint version. I am trying to switch over to T-Mobile version of Oreo. Is it still possible to do and if so where exactly should I start. Confused on if I need to downgrade my firmware first and if I still need to do the carrier switch as well? Please if someone can point me in the right direction. Thank You
[Samsung Galaxy Note 8 Guides, News, & Discussion] BlueFox721:
Maybe flash the official firmware for your device in the regular 3.13.1 Odin and then flash unlocked using patched 3.13.1
[Samsung Galaxy Note 8 Guides, News, & Discussion] BlueFox721:

Need help. Have factory unlocked note 8 . Flashed att bra8 so now it's xaa/xaa/att and it won't OTA to Oreo. Can I just flash the Oreo complete carrier firmware over my current setup?
[Samsung Galaxy Note 8 Guides, News, & Discussion] BlueFox721:
Reboot to recovery, perform factory reset, back out to main recovery menu, select boot to bootloader...

Open new existence of Patched Odin 3.13.1, run as administrator.

Connect device, make sure Odin shows "added".

Add 3CRC1 BL to BL, AP to AP, CP to CP, CSC to CSC, leave USERDATA blank.....

Flash...

Post screenshot of the error if any

I tried your recommended steps, but to no success. Still got the same results. Not sure how to post a screenshot. How do I check if ADB is setup correctly on my computer?
[Samsung Galaxy Note 8 Guides, News, & Discussion] BlueFox721:
You don't need adb for just flashing unlocked....

You may need to downgrade to 3BRA firmware then flash unlocked
[Samsung Galaxy Note 8 Guides, News, & Discussion] andyli83:
I tried flashing unlocked XAA 3BRA when the phone had 3BRA (official verizon firmware) before. Got the same problem. So I am thinking it's something I am not doing right.
[Samsung Galaxy Note 8 Guides, News, & Discussion] BlueFox721:
Does the device show as added in Odin?

Do you have debugging enabled in developer options?

Have you tried different USB port?

Have you tried different USB cable?

Can you downgrade to 3BRA version with Regular Odin 3.12.7?
[Samsung Galaxy Note 8 Guides, News, & Discussion] seanthabarber:
Sir when I do this step in the carrier switch steps are the quotation marks required of just the new carrier code that I am trying to switch to

or

My goal is to end up on oreo. At what point do I flash the ATT firmware? Or should I even? Prior to oreo, xaa/xaa/att worked fine (other than ATT wouldnt push oreo OTA to me) Just want to make sure everything will work this time. (donation inbound)
[Samsung Galaxy Note 8 Guides, News, & Discussion] BlueFox721:
So if you have XAA and ATT complete Oreo, you may still get the XAA Wi-Fi calling....same as unlocked XAA or unlocked ATT oreo...might not be any difference in the two....

Best way is to check each by just skipping the setup....until you find which works best for you...
[Samsung Galaxy Note 8 Guides, News, & Discussion] borijess:
I am having the same issues. I got to speak with an advanced tech. He said it's not my imei cause it shows it has the right provisions. He was going to try and fix the issue but couldn't cause I just preordered the IPhone X for my wife. Something about it would cause my pre-order yo cancel. So I have to wait until I get the phones before I call back and get my Wi-Fi calling fixed. Will keep u guys updated. I purchased my note 8 at Samsung unlocked carrier and flashed the AT&T software.
[Samsung Galaxy Note 8 Guides, News, & Discussion] flashhsalf:
I'm in the same boat. I got them to unlock the t-mobile phone temporarily for about a month.

If I were to flash AT&T's firmware, would it essentially keep my phone from locking back up becuase the Tmobile app has no way to contact the server to relock my phone? Unless the app is keeping the time internally in which case there must be a way to freeze/uninstall it since we have root?
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcrompton:
If you guys follow the instructions t to change carrier and then flash the AQH7 ATT CSC and userdata then it should work on ATT

IF

You go to ATT store and play with an ATT N8 and copy the IMEI number down. Get ATT to put that IMEI number in your account (you can do it yourself if you are a business customer), then it will work

But with out root you'll have some ATT bloat

I'm in the process of getting my tmobile note 8 carrier unlocked with tmobile. I bought it thru Samsung so it may take up 72 hrs to unlock it. My question is...I want to take advantage and switch to Boost Mobile (current Promo 5 lines for $100). Once its fully carrier unlocked wld it be best to install the stock unlocked firmware or the sprint firmware or is there a boost mobile firmware that I can install? I know currently my phone is not carrier unlocked and boost mobile said I can't use the phone yet...until is fully unlocked. Any info is greatly appreciated. Which Firmware you think I sld install for what I'm trying to do? I'll be cancelling tmobile siince 5 lines for $100 sounds tempting with Boost Mobile.
[Samsung Galaxy Note 8 Guides, News, & Discussion] BlueFox721:
You can flash unlocked or the carrier that boost uses but it might be best to follow the switching carrier guide to change the csc code to boost mobile and then flash the firmware you wish to use...
[Samsung Galaxy Note 8 Guides, News, & Discussion] Krayziepop:
Hey Bluefox. So I have been using the ATT firmware for a while now and frankly the unlocked U1 firmware worked FAR better. I even had better signal in most places. Wifi calling sucks and VOLTE is not that important anymore. I want to go back to unlocked, do I need to follow Carrier switching, or can I simply flash the stock U1 over my current ATT firmware and be back where I started? Any suggestions?

I wonder what the difference is. I have the unlocked directly from Samsung and need to have the VOLTE as I use the hotspot a lot and if I get a phone call it's useless as it's too slow.
