Right the last code requires root...but this guide is for changing carrier...for instance, if you attempt to install Verizon Firmware on T-MOBILE you will still have T-Mobile bloat...this changes T-Mobile csc to (for example) To Verizon so you can flash Verizon and have Verizon bloat...I will update to include that it does not change the device csc....thank you...

There is a root method on S8+ for doing this though, I may add it later in a new thread...but for our device...of course our root may not allow it...:rolleyes:

Worked like a charm! Switched the phone from Verizon to TMO. I encountered one hiccup, but that was easily remedied. I got the '$ADB_VENDOR_KEYS is not set' error when I tried sending the reboot command through adb. I fixed this by deleting the adbkey and adbkey.pub files from in Users/YourSystemName/.android and then generating a new set of keys using

adb keygen C:\Users\YourSystemName\adbkey

and placing the newly generated keypair in the .android folder. You can try generating the keys in the .android folder directly, but I had some trouble with that (something about access and permission). Once you do this, try

adb reboot bootloader

again and it should work!
[Samsung Galaxy Note 8 Guides, News, & Discussion] BlueFox721:
Yeah...I just factory reset to solve it...but adb command is quicker...glad it worked..:svetius:

For flashing unlocked firmware, I see

Will flashing carrier's unlocked firmware include all the bloatware? Or is it just different CSC files for connectivity?
[Samsung Galaxy Note 8 Guides, News, & Discussion] BlueFox721:

I flashed the ATT firmware to my unlocked SM-N950U1 this morning using your guide, and everything is working perfectly. No startup issues, no snags. Thanks for making it easy to follow along. VoLTE, Wi-Fi calling, Advanced Messaging, Video Calling, etc all are working perfectly without a call to AT&T. Lots of bloat, but I disabled the bulk of it with BK.

Thank you!

I am exactly in this situation but could you please confirm that the CDMA freq /band will be working once we flash the CSC even with XAA/XAA/TMB?

Thank you
[Samsung Galaxy Note 8 Guides, News, & Discussion] BlueFox721:
If you use carrier switching guide to change to the desired csc, for instance changing from TMB to SPR...you will then flash your intended firmware like SM-N950U SPR...as long as your device is carrier unlocked or factory unlocked...you should be able to insert desired carrier SIM, like Sprint, and activate...the last three of code are for product origination...your SIM and firmware control the connectability not the last three of product code...S8+ users have even stated they flashed on Canadian devices or Canadian firmware and connected...in other words, if you use CDMA SIM you will connect
[Samsung Galaxy Note 8 Guides, News, & Discussion] gottria:
Already flashed the ATT firmware and everything is working. What was strange is even though I re-flashed XAA and then the USERDATA and CSS from the ATT Rom some of my login info of my apps were there. For example on a fresh boot after a flash and reset Nova was my default launcher, Blink and my eero app still had my login info. After flashing the ATT firmware I had to enter all my login info to those same apps.

I have a good question. I flashed my phone from Note 8 unlocked firmware to Verizon firmware, something that i notice is that I couldn't find the system update button, when Samsung decide to send Oreo update, how Ican i do it? do i need to flash back my phone to original firmware????
[Samsung Galaxy Note 8 Guides, News, & Discussion] BlueFox721:
Yeah, in order to be clean XAA from start have to follow the switching carrier guide and change to XAA first then flash XAA firmware without sim..clean

Okay, one more question... It just clicked with me right before I hit the start button in Odin - I flashed the ATT Userdata package in the UMS slot when I Odin flashed the whole ATT carrier package. I just seen there is not a Userdata file in the unlocked firmware zip... is there anyway to factory flash the userdata back to unlocked stock, or am I stuck with the ATT bloat now? Thanks again man!

Thank you bro
[Samsung Galaxy Note 8 Guides, News, & Discussion] black96ss:
Is their a USERDATA FILE for XAA????
[Samsung Galaxy Note 8 Guides, News, & Discussion] Krayziepop:
I have a sneaking suspicion there is not an USERDATA segment in the unlocked firmware... which begs the question, how do you get rid of it through an Odin flash? I haven't tried just flashing the rest of the package by itself to see if it wipes USERDATA or not, but I feel like it just won't touch that partition if nothing is loaded in the UMS slot. Hopefully someone here can shine a light for us. :fingers-crossed:
[Samsung Galaxy Note 8 Guides, News, & Discussion] kbonnel:
Quick question(s). I plan on flashing my Verizion Note 8 today to a TMB firmware. I have read and reread the instructions enough to basically have them memorized :) My questions are:

1. do I need to enable the USB Debugging on the device before I do any of the work? I don't believe I need it for the ODIN portions, but wasn't sure if it needed to be enabled for the adb activities (carrier switching). I haven't found any mention of it in this thread, nor any of the S8/S8+ threads, so I suspect I don't need it.

2. I also didn't know if I should remove any google accounts from the phone prior to the reflash, or if I should even do a factory reset prior to the reflash.

3. I couldn't find any specifics on if I should leave any SIM cards inside the phone, so I figured not having any installed would be best?

4. Should I connect the device to adb prior to any work? I have read a few folks running into "key" issues, and I wondered if do an initial adb activity prior to the flash would make any difference.

My process flow was going to be as follows: (assuming no need to wipe the device or remove any existing account data i.e. google account, etc)

- remove Verizon sim card

- follow carrier switching steps

- follow standard firmware installation steps

- when firmware flash is completed and booted up (i.e. initial configuration of a new phone), insert tmobile SIM card and do a reboot of device and setup device

Is that an acceptable process? Or should I just put the tmobile SIM card from the start?
[Samsung Galaxy Note 8 Guides, News, & Discussion] black96ss:
Pretty sure usb debugging has to be on for adb commands, I would leave the sim card out. Usually the sim card being left in or out doesn't matter but I've read that some people had better success with some csc features activating when installing the sim after flashing/boot up.

I have done a carrier to carrier flashes on both the s8 and note 8. The only variation i haven't done was flash carrier firmware on unlocked and back to unlocked. I'm not sure if the carriers USERDATA will stick since the the unlocked XAA doesn't have a USERDATA file to flash via ODIN.

Hello everyone. I have the unlocked version of the firmware installed on my tmobile note 8. Not rooted. With the tmobile software I was getting 7 to 8 hours sot. Now I'm getting 5 to 6 hours sot. Is anyone else experiencing quicker battery drain on the unlocked firmware? Please let me know. I opened a thread on the tmobile forum but didn't get any info on this matter.
[Samsung Galaxy Note 8 Guides, News, & Discussion] borijess:
Update- I tried using the imei of an IPhone X. Before using the imei of the X I had visual voicemail working. When switched the sim card to my note 8 the Wi-Fi calling started to work but visual voicemail did not work anymore. Went back to my note imei and Wi-Fi calling is not working and visual voicemail is back.
[Samsung Galaxy Note 8 Guides, News, & Discussion] kbonnel:
I wanted to give an update on the update of my Verizon Note 8 to a T-Mobile Note 8. It worked successfully.

I did run into a weird issue, that appeared to be related to the Samsung USB drivers I had installed. (1.5.64 or something similar) I got to the first part of opening ODIN and connecting my phone. Odin indicated it was connected, and I loaded up the COMBINATION file from the carrier switching steps.. Upon starting the Odin process, it eventually crashed as Odin reported it could not reach the phone. I disconnected everything, uninstalled the existing USB drivers I had installed, rebooted, and reinstalled the USB drivers from the Galaxy S8+ thread (direct from Samsung, version 1.5.51 I). NOTE: I tried installing the USB drivers from this thread, but the installer would never start. To be safe, I also switched my USB connection to a different port (regular USB 3.0, vs the previous USB 3.1 type C connection).

After this, the next little issue I had (which was reported in the process) was the factory binary screen not showing up after the initial flash of the COMBINATION file. I waited for approx 5 minutes before I decided it wasn't going to happen. (I also found a youtube video of a very similar process that showed the typical time frame from initial COMBINATION flash to loading up into the Factory Binary screen.) I did a factory reset/wipe per the suggestions and upon the reboot it loaded into the Factory Binary screen..

Finally, the last area that I had confusion on, due to it not being in the instructions, was on "Step 23 - After menu pops up, Scroll down until you find an "XAC" option. Select "XAC" and then select "Install".". When I clicked install, another little pop up happened that asked if it was for a full install or a network install, I selected Full install. Hope that was correct :)

That was it, every other step within the carrier switching and the standard firmware flash went perfect. The phone has been working as expected.

Thanks !

Are there any mirrors for the carrier firmwares? (VZW). The Updato link will take 12 hours to download over my gigabit connection.

Also, what exact carrier features are lost when using the unlocked firmware with carrier (VZW) CSC and USERDATA vs using full carrier firmware?

Thanks

[Samsung Galaxy Note 8 Guides, News, & Discussion] MrMike2182:
That's because the firmware numbers and letters change.. They don't stay as BRA1 if you want Oreo you can download it and then flash it yourself using odin and it'll work just fine.. This firmware is for the China version of Oreo N9500ZCU2CRD5 and this one is for the Hong Kong version of Oreo N9500ZHU2CRD5 just download the one you want and flash it.. The reason yours keeps saying up to date is because someone (possibly your carrier) flashed the BRA1 firmware and it just won't update but you can manually do it..

Hey guys I just purchased a n950u1 unlocked note 8. I use total wireless for service, I have tried flashing verizon firmware,ums user data, and used shortcut master to turn VoLTE option on and cannot get it to show 4gLTE no matter what..so during calls I have no data access..I have not tried rooting yet..If possible can you guys tell me how to make this work ? If Root is necessary I will try that. thanks
[Samsung Galaxy Note 8 Guides, News, & Discussion] MrMike2182:
Root is not necessary to get your service working.. I would suggest that you go in your settings then connections and look for mobile networks and in there you should check your APN and make sure it's what it's supposed to be for Total Wireless because if it's not then it will not work.. I also suggest that you flash the unlocked N950U1 firmware that you had on the phone because having Verizon firmware can prevent you from changing stuff.

[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
No! You need to flash it to the carrier unlocked U1 firmware first, then flash to the TMB U firmware. When flashing though, firmwares being flashed must have the same or a newer bootloader than the firmware you are flashing.
[Samsung Galaxy Note 8 Guides, News, & Discussion] VenomMOD:

So I should flash the U1 firmware first then the TMB firmware? Do I still need to follow steps in the Post #2 of this thread to switch the carrier? I was told somewhere else that all I needed to do was flash the TMB firmware using Odin.
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
If your device is on a different U firmware or the W firmware, flashing to the U1 is a mandatory step to ensure that your device converts properly. This is specifically for SnapDragon North American devices. If you have a device that isn't from North America, the steps might vary. The most important steps to getting your conversion done right are making sure you never use the HOME_CSC's from any firmware, and flashing to the U1 before flashing to a different carrier U firmware. You need to make sure both firmwares you are flashing use the same bootloader version your device currently has or that the U1 and U firmwares you are flashing both have a newer bootloader. You can not flash a firmware with a bootloader version older than your device currently has. Back up your device before attempting this, as the process will wipe your device, which is necessary to ensure the conversion goes smoothly.

[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
Does your device currently have the v3 bootloader or older? The version of the U1 you linked to has the v3 bootloader. You can not flash to an earlier bootloader. U1 firmwares start with N950U1EU. The 3CRC1 part contains the bootloader version, which is the 3.
[Samsung Galaxy Note 8 Guides, News, & Discussion] RootMyNote4Please:
Mine is currently N950USQS5CRI4 so I guess I have V4?
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
You have the v5 bootloader, hence the 5CRI4. You should look for a v5 bootloader U1 firmware to flash. Updato or SamFirm might be the best places to look.

[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
Everything should flash fine. Make sure you have USB Debugging enabked in Developer Ootions, make sure you have the modded or oatched ODIN, and make sure you install the drivers in Download Mode before ooening ODIN to flash. Back up your device and if the zio has two CSC files, do not flash the HOME_CSC.
