found a different version of BK and now I figured out backup and restore and face unlock is back..... still angry about samsung locking **** down to a point you dont have any real control over your OWNED device... sorry for the rant..

Okay, I downloaded the unlocked Oreo firmware and the AT&T Oreo firmware (so I could use the modem file from it). I then used PrinceComsy Odin, loaded all the applicable files from the firmware files, pushed Start and a few seconds later it immediately failed. Why did this go wrong since I followed the instructions as listed in post 4? There is even a note to use PrinceComsy if going from Carrier Firmware to Unlocked firmware so that is what I used.

How can I make this work? I'm worried to try it again for fear of bricking my phone. I'm currently on 7.1.1 with baseband BQL5

Edit: N/M - I used the newer patched version of Odin per the note at the top of the OP since I was using Oreo and it worked. Adding back in apps right now and connectivity using the AT&T CP file seems just fine.

Hi all, I tried to look through the thread for an answer but couldn't find one. Forgive me if I missed it but I am currently on the unlocked oreo firmware. I would like to flash it to the AT&T oreo firmware but it is a verizon phone originally. I keep getting errors when trying to downgrade to BR* firmware (Nougat). Can anyone give me direction on what i need to try?

Hi, I'm newbie with Android here.

I got a T-Mobile Note 8. How can I unlock the phone? I have tried to flash to unlocked firmware (N950U1UEU3BRA5_N950U1OYM3BRA5_XAA), but it asks me the Network Unlock Code whenever I insert the non-Tmobile SIM card.

Will I have to use Switch Carrier method?

TIA
[Samsung Galaxy Note 8 Guides, News, & Discussion] gregcapps:
You have to pay to have it unlocked or call your carrier for an unlock.
[Samsung Galaxy Note 8 Guides, News, & Discussion] Nickitt:
It's free through carrier if customer has paid off their phone.
[Samsung Galaxy Note 8 Guides, News, & Discussion] gregcapps:
yes, it is, I've done it with T mobile in the past, they email you unlock code
[Samsung Galaxy Note 8 Guides, News, & Discussion] dwalkingdead:
Need Help.

Originally my note 8 was from Verizon. I successfully flashed it to Unlocked US version. There was some kind of glitch so I flashed it back to Verizon. Now my phone has the latest Verizon firmware but it is not a verizon phone like before. It is just like unlocked phone. My phone shows XAA/XAA/VZW and not VZW/VZW/VZW. Basically, I have a Unlocked US version phone with Verizon firmware.

Any help to get back to original Verizon phone would be appreciated.
[Samsung Galaxy Note 8 Guides, News, & Discussion] arpitarora55:
Its mentioned in the starting of thread that flashing unlocked firmware won't unlock your device of your device is carrier locked. You have to pay.
[Samsung Galaxy Note 8 Guides, News, & Discussion] gregcapps:
Or contact the carrier, they can unlock it. Possibly free of charge.
[Samsung Galaxy Note 8 Guides, News, & Discussion] minhtrimatrix:
I bought the phone from Samsung website.

I requested the unlock from Samsung, and they said I should contact T-Mobile since T-Mobile is my carrier.

Then I asked T-Mobile but they told me that they didn't have the IMEI on their database.

I see that there are some remote unlock service on eBay, will that method work?

Thanks a lot
[Samsung Galaxy Note 8 Guides, News, & Discussion] gregcapps:
Supposedly, yes it should. I cannot speak from personal experience however. I've only had a phone unlocked by getting the unlock code from T-mobile years ago.

Question. I just purchased an unlocked us version note 8 and this is my current oreo build R16NW.N950U1UEU3CRC1. I'm currently on tmobile...What are the benefits of flashing to a tmobile firmware?
[Samsung Galaxy Note 8 Guides, News, & Discussion] Stevieboy02008:
You'll get Tmobile bloatware and gain wifi calling. I think so anyway.
[Samsung Galaxy Note 8 Guides, News, & Discussion] Nickitt:
On the flip side, package disabler can take care of the bloatware :)

Only $2.49
[Samsung Galaxy Note 8 Guides, News, & Discussion] ahfu25:
Is that all? Because wifi calling is working for me already. If so I'll just stick to my current firmware. Thank you!
[Samsung Galaxy Note 8 Guides, News, & Discussion] Stevieboy02008:
You're welcome. I'm on Verizon as a carrier but I use the unlock phone and firmware and Like it more. I flashed the Verizon one and used it for a week. Was not a fan

Hi I am new here. My AT&T is unlocked. What firmware should I download?
[Samsung Galaxy Note 8 Guides, News, & Discussion] illusivenick:
For AT&T users I just noticed there is a new carrier specific Oreo posted yesterday on sammobile.

PDA: N950U1UEU4CRD7

CSC: N950U1OYM4CRD7

www.sammobile.com/firmwares/galaxy-note8/SM-N950U1/ATT/

Too bad it's bootloader 4 as I don't was to upgrade yet, but if anyone with AT&T model upgrades to this please let us know how it's running. Thanks
[Samsung Galaxy Note 8 Guides, News, & Discussion] archie87:
FYI, this is for the unlocked Note8, not the carrier specific AT&T version. All of the firmware versions are the same for the unlocked model even though it is separated by carrier.

Sammobile doesn't have the firmware for the AT&T version which is curently on N950USQU3CRC2 I believe.
[Samsung Galaxy Note 8 Guides, News, & Discussion] illusivenick:
Thanks archie87 good catch. I got excited when I saw it was uploaded yesterday.
[Samsung Galaxy Note 8 Guides, News, & Discussion] jmdomini:
So I tried this experiment yesterday now that I finally had a BL4 base US firmware to fall back on. I hoped that it might be a less locked down alternative to the XAA firmware as we can no longer access the IMS settings there. Unfortunately it did not work out. First of all running on Sprint I was not able to get any connectivity on the CDMA side of things at all. I tried both flashing the sec_omc.zip as well as the entire CSC file from ODIN from the U firmware. It seemed like the phone didn't recognise the existence of the CSC at all. I also inserted a T-Mobile SIM, which did appear to work fine. So just from a basic test GSM is a go, CDMA does not work.

In addition you can not access the IMS settings in the Canadian firmware either, so really nothing to gain by going this route any way. :(

I am curious why CDMA seem to be non-existent in the Canadian firmware however. I did get into the menu to enable bands, and the only options were TD-SCDMA,LTE,GSM and WCDMA. Nothing there for legacy CDMA unless it's merged with WCDMA.
[Samsung Galaxy Note 8 Guides, News, & Discussion] Jay5583:
So I think I'm finally ready to try and make the jump to the U1 firmware... does anyone have a faster link to the latest 4CRD7 files? I'm trying to get it from SamMobile but it's going to be several hours.
[Samsung Galaxy Note 8 Guides, News, & Discussion] gregcapps:
I used the samfirm tool. Downloaded pretty fast. I do have 100 mbps cable internet tho.
[Samsung Galaxy Note 8 Guides, News, & Discussion] Jay5583:
I just realized what SamFirm was. Have it downloaded already. I have gigabit ethernet :)

---------- Post added at 07:25 PM ---------- Previous post was at 07:22 PM ----------

I do have one more question if you can help..

I downloaded the U1 file using region VZW...do you know if this will have the Verizon modem or is there a different file to use for that? End result I'm looking to do is U1 firmware with any carrier specific files for reception/data etc.
[Samsung Galaxy Note 8 Guides, News, & Discussion] gregcapps:
Can't really answer any questions concerning the u1 firmware, sorry.
[Samsung Galaxy Note 8 Guides, News, & Discussion] ahfu25:
Whats the difference between USC and XAA versions? I want to download the version that would be downloaded through the device coming from the march patch that came installed on my U1 I got from samsung. Thanx
[Samsung Galaxy Note 8 Guides, News, & Discussion] hq15955657:
it's all the same, you could use all kind of carriers in the USA, and enjoy the calling and data just with the samsung logo.

US unlocked is nice,

enjoy.

AT&T 4CRD7 Question

If I odin AT&T model (CRC1) to the latest N950U1UEU4CRD7 will I ever be able to get back to stock AT&T since I'll be stuck on an unlocked version of boot loader 4?

What will my service provider SW show after flashing N950U1UEU4CRD7? It currently shows ATT/ATT/ATT

I'm wondering if there's a way to always get back to ATT/ATT/ATT after flashing 4CRD7? The only stock oreo AT&T firmware I can find is N950USQU3CRC2...

Thanks
[Samsung Galaxy Note 8 Guides, News, & Discussion] adityats2020:
The latest update seems to have updated the bootloader version to 4. I am running T-Mobile firmware N950USQU4CRD7. Can I still flash unlocked firmware N950U1UEU3CRC1 over this?
[Samsung Galaxy Note 8 Guides, News, & Discussion] gregcapps:
No, you can't downgrade the bootloader.
[Samsung Galaxy Note 8 Guides, News, & Discussion] illusivenick:
I found the stock SM-N950USQU4CRD7 load at the at&t sub forum. Running U1 CRD7 with stock modem and CSC.
[Samsung Galaxy Note 8 Guides, News, & Discussion] adityats2020:
Can I use this version N950U1UEU4CRD7 I found in updato? I am a bit unsure because unlocked XAA versions are only available for N950U1 and not N950U.
[Samsung Galaxy Note 8 Guides, News, & Discussion] gregcapps:
I've never dealt with carrier changes changes, so that I'm not sure about. I think it should work from what I understand, but you better do your research before flashing unlocked firmware.
[Samsung Galaxy Note 8 Guides, News, & Discussion] illusivenick:
Yes that's what I did and I have AT&T model.

Or if you want stock you can flash the SM-N950USQU4CRD7 here:

https://xdaforums.com/att-galaxy-no...ta-updates-t3756025/post76536655#post76536655

Even though that stock firmware is under AT&T section is actually contains Tmobile userdata (I didn't flash userdata cause I don't see any reason to).

I actually flashed a combo of N950U1UEU4CRD7 (no bloat) with csc and modem from SM-N950USQU4CRD7 (for best network performance).

What files should I use?

Thank you for this but I have a simple question. My Tmobile Note8 is stuck on the Samsung boot animation. I want to take it back to stock firmware. That said, my simple question is should I include all the files?, What of HOME_CSC should I use that too and the meta? I know these are noob questions but I am a noob :)
[Samsung Galaxy Note 8 Guides, News, & Discussion] cfclay:
I used Odin to update my AT&T Note 8, SM-N950U, to TMobile firmware. It appears, from what I read on forums, to have installed successfully, although I thought the phone would have been wiped.

The phone appears to work as intended. VoLTE (this means the internet works while your on the phone right?), And even Wifi Calling works.

The issue is I'm not picking up Tmobiles 700mhz network. The forums often say to check your IMEI in TMobiles BYOD app to check full compatibility, and this At&t variant's IMEI would indicate that it WONT pick up the 700mhz network....yet some forums indicate this m-i-g-h-t get resolved through flashing different firmware.

This is a thorough thread, but I haven't found this answer. Can anyone comment on this ?

How do I install the tmobile rom but with the unlocked radio?
[Samsung Galaxy Note 8 Guides, News, & Discussion] BlueFox721:
Just having T-Mobile SIM and Firmware will set that...what i mean is did you follow the switching carrier guide and change the device CSC code with the factory binary....

This makes it to where the network can be fully T-Mobike and have access to yhe band....but it has to be available in your area....

For instance, my area does not have band 41 for Sprint yet, so getting access to band means nothing...

But, all the US devices are identical, as in same hardware...it is the software that blocks bands...and the best way to get T-Mobile is to follow the guide to ensure that you have TMB as device code and then flash T-Mobile Firmware , AP, BL, CP, CSC (not HOME_CSC), and USERDATA....

[Samsung Galaxy Note 8 Guides, News, & Discussion] PUTALE:
Hello, Guys

Need a little bit of helps here. I just got Verizon Note 8 with firmware (N950USQU3CRC2). Since my carrier is T-Mobile, I am thinking of following the guide to make the phone work better on GSM network. From what I gathered, I can flash the phone so it runs like the phone is bought from T-Mobile (ie it will be fully compatible with network’s band/radio and use all of the feature) or I can even choose flash unlocked rom to make it behave like unlocked (which I assume since Verizon phone is factory unlocked, this would essentially make the phone be fully unlocked).

I have a few questions that I hope someone can help to answer before I flash so I don’t brick the phone. If I understand correctly, this is what I need to do

1-	follow the step 1 in the guide here to switch carrier.

a.	I need this file (COMBINATION_FA71_N950USQU3ARA3, and HOME_CSC_OYV_N950WOYV3BRA5) the since I have QU3 bootloader and I want to switch from Verizon to T-Mo or unlocked.. Am I correct?

b.	I need to use Use odin 3 PatchedD for flashing (since I am currently on Oreo firmware?)

i.	The first post mention something about “Edit the "UMS/PATCH" of Odin3.ini file for Odin and Modified Odins from "0" to "1" and save ("Ctrl S")” (Do I need to do this??)

ii.	I am a bit confused as to if I need to flash the Canadian HOME_CSC file. After flashing the combination file, I think I need to in order to sort of reset the phone’s current setting to switch carrier. Am I correct here?

iii.	I am thinking of changing the phone to the unlocked version, so am I correct that I need to follow the guide and use “XAA” when I select CSC (and also flash the “N9501U3CRC1” firmware and follow step 4)

iv.	If I want to flash to T-Mobile, then I would select “TMB” for CSS and flash “N950USQU3CRC2” firmware (and follow step 3), correct?

v.	When I flash the firmware, can I flash the N950U1UEU4CRD7 instead so it has the latest security update? Would this cause the bootloader to upgrade to v4 that prevents future flashing?

A couple additional questions:

1-	Does this method prevents OTA updates?

2-	If it did not prevent ota update, then would ota update flash the bootloader (ie prevents me from able to switch to another carrier/firmware in the future? I would think so. Thus, it is probably best to disable automatic update, right?

3-	If I do disable ota automatic/ota update? Can I upgrade to future software for security patches and all without touching the bootloader?

Sorry for tons of questions, just want to be safe. Thanks a lot guys

[Samsung Galaxy Note 8 Guides, News, & Discussion] bogarty:
Thanks [MENTION=5649240]BlueFox721[/MENTION] for this amazingly thorough guide and for answering my question about which combination & home_csc files to flash to turn my unlocked, old school Nougat ridden, AT&T Note8 into a T-Mobile bloat rocking Oreo beast. Everything looks great now on the newest CRE1 firmware. :)

(In case anyone else has the same question about an already downgraded(early Nougat firmware) device that they want to carrier switch and upgrade to Oreo, then they can check out the answer to my question on this post HERE.)

P.S. My OCD really wishes that I could change the Product CSC, so that it's TMB/TMB/TMB instead of TMB/TMB/ATT, but I understand that it can't be changed. Hopefully I'll be able to actually get future OTA updates now though through T-Mobile regardless. :)

Unable to Flash

I seem to be having an issue when attempting to modify my Unlocked Note 8 straight from Samsung... Whenever I attempt to flash anything (mostly just trying CSC and USERDATA to restore carrier functionalities), I get "<OSM> All threads completed. (succeed 0 / failed 1)." I have tried factory reset, enabling USB debugging, and I'm able to get into the Downloading... screen. Once there, ADB Devices shows nothing. When the phone is on, I get the phone listed in adb devices. Any ideas for help? Is the firmware listed in the OP too old since my build is CRE1? I'm kind of at a loss after trying with every posted Odin version, etc.

Thanks!

I'm trying to get WiFi calling, video calling in the phone app, and VoLTE enabled. These were lost when it upgraded to Oreo, and the installation of the shortcut apps shows the usual permission denied error Oreo introduced when trying to get int IMSSettings, etc. If you're saying just insert my SIM card, that doesn't enable everything I'm looking for. Thanks, though. If you're saying something else, sorry, I don't understand.

Hey guys I have a lil problem. So I bought a Note 8 off a person on Craigslist or some. Apparently he didn't pay the bill (I kinda expected that). It still works with my Cricket sim though so I'm not complaining much. I want to sell the phone though and want to get it unlocked first. I installed the XAA rom on it (N950U1) prior to unlocking it. I tried to do a remote unlock by paying someone that had unlocked my T-Mobile Note 5 on eBay but I think it didn't work because it has the XAA rom now and not the ATT Rom.

Please what steps should I follow to get back an ATT rom so that I can unlock the device? I am currently on the March 1st firmware for the XAA software.

Build Number: R16NW.N950U1UES4CRE1

Baseband: N950U1UES4CRE1

You can get the home_csc from downloading the Canadian firmware (n950w) from updato and taking the home_csc out...

Can you please help me find links to the 4 Bootloader combo? As well as the latest Verizon firmware I could flash please?
