Currently on N950USQU3CRC2 verizon firmware. Can I downgrade to N950USQU3BRA5? I believe I need to go back to N950USQU3BRA5 to switch carrier? Is this correct? Also, if downgrading is possible, will it trip KNOX?

thanks in advance
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
The bootloader has to be the same or newer to flash to. Both of the firmware you mentioned are on the v3 bootloader, so that will work. If you are flashing backwards but the same carrier firmware, you should be fine. If you want to flash to another carrier firmware, you must flash to U1 first.
[Samsung Galaxy Note 8 Guides, News, & Discussion] dwalkingdead:
What is U1? Is U1 the unlocked unbranded version? Mine is SM-N950U. Do I have to change it to U1 by flashing unlocked version?

Originally, I had Verizon note 8, then I flashed to unlocked US version. Then I reflashed Verizon firmware back again thinking it will just go back to original Verizon version. But it did not switched to back to factory Verizon. I now have Verizon firmware (N950USQU3CRC2) but it's not Verizon phone like before. My phone says XAA/XAA/VZW instead of VZW/VZW/VZW. I believe I have to follow Carrier Switching Guide to get back to original state (Verizon).
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
The U1 is the unbranded US firmware. If you are going to stick with the Verizon firmware, there is no need to flash to U1. If you wanted to change from Verizon to T-Mobile or another carrier. Then you would have to flash tp the U1 first before flashing to the different U carrier firmware.

I assumed the S4 number in my firmware related to bootloader 4. My note is stuck with frp lock. I tried flashing a combination file someone sent me also 2 other ones. And the same firmware but Odin says fail every time. Or device mismatch or something. Tried the patched Odin and prince Odin ect. I removed frp on my note 5 awhile back but this is drivin me insane. Any idea exactly which combo file I need? Also I know adb isn't enabled in developer setting because I can't get to it because of the frp. It will go into download mode and recovery.
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
USB Debugging must be enabled in Devekoper Options for ODIN to be able to flash. The bootloader number is the 3 in your firmware version, which is 3CRC2.
[Samsung Galaxy Note 8 Guides, News, & Discussion] DesertEagleSlim:
OK so, here's the delima. It's FRP locked. Therefore I can't get to developer options to enable. Odin recognizes the phone when connected. Any idea?
[Samsung Galaxy Note 8 Guides, News, & Discussion] gregcapps:
Can you just let the frp lock expire so you can login. I locked myself out for about a day and a half. Didn't realize that if you try to login during the 24 hour period, the timer resets.
[Samsung Galaxy Note 8 Guides, News, & Discussion] DesertEagleSlim:
I've never heard of FRP expiring. Phone will not allow you to set anything up (because it was factory reset) until you enter the previous owners Gmail and password. It's stuck. And no I don't have either. (no it's not stolen, imei is not black listed ect.)
[Samsung Galaxy Note 8 Guides, News, & Discussion] gregcapps:
Ok in my case I had locked myself out and had to reset the password and because of that I couldn't login to my gmail for 24 hours. But like I said if you try anytime within the 24 hours the timer resets. So on my case it did expire in a way sorta.....
[Samsung Galaxy Note 8 Guides, News, & Discussion] prican25:
You're best option would be to search for a way to bypass the FRP if that's the case then come back and try this.
[Samsung Galaxy Note 8 Guides, News, & Discussion] DesertEagleSlim:
Try what? I tried flashing the combination file for v3 bootloader. Gives me an ald.elf error. Looked into that error and someone said that's because the bootloader is newer. However someone said the firmware I have on this note 8 is V3.. Apparently not or the combo file would work. So I'm trying to locate a v4 combo file. If it was v3 for sure I would try rooting with samfail but I don't want to brick the phone trying to root with the newer BL. Sigh, I've been messing with this phone every morning for almost a week. Just wanted to get past the frp so I could literally use the phone instead of the V20 I'm currently using. ANY HELP at all would be greatly appreciated. Thanks in advance.
[Samsung Galaxy Note 8 Guides, News, & Discussion] vincentallen2:
My phone is updated with t-mobile software somehow, Is there a version 4 unlocked carrier firmware available for download?
[Samsung Galaxy Note 8 Guides, News, & Discussion] prican25:
Sorry as I meant for you to get your FRP problem fixed and comeback here to try it again but I now see why you need the correct combination file so you can do that. Just have wait and can't help with FRP as it's a touchy subject on the forums.
[Samsung Galaxy Note 8 Guides, News, & Discussion] DeathGrin13:
Hi BlueFox721 or anyone,

If I am on Sprint CR2 Firmware but want to flash AT&T firmware do i still use the two below files for carrier switching? Even though they are BR* and not CR*?

COMBINATION_FA71_N950USQU3ARA3

HOME_CSC_OYV_N950WOYV3BRA5

Thank you!
[Samsung Galaxy Note 8 Guides, News, & Discussion] DesertEagleSlim:
No problem brother. Got it sorted out. Now it works back on original firmware and running great. However it's still t-mobile, I've switched to att I should have flashed the att firmware huh?

Are you using your PC? I've had the same issue when using my phone, no matter how many times I try it.
[Samsung Galaxy Note 8 Guides, News, & Discussion] taikoboi:
Hi I purchased my samsung note 8 through samsung.com using Sprint Carrier. I had sprint unlock my imei since its paid off but when I insert a different carrier sim card, it tells me to contact sprint to unlock. I called sprint they confirmed that the phone is unlocked on their end. The reason why I'm posting here is because I flashed the phone to the unbranded version and later on reverted it back to the Sprint variant version. So I'm not sure what to do and sprint can't figure out why the phone itself won't allow a different sim even though its unlocked on their end. Any help would be great thank you.

Hi! Love you guide but need your advice and help...

[MENTION=5649240]BlueFox721[/MENTION]

Hi I recently bought a Note8 from China(i know a guy who sells imported refurburished cell phone) its on AT&T but im able to use sim of other countries...the phones working fine..

The problem is I am not recieving any software updates...I contacted AT&T they said that the phone need to be in USA to recieve updates...which is not possible time being...My baseband is N950USQU2BQJA

My problem is:-

1) How should i go about updating my phone using the above guide...should I use the unlocked carrier section(when i checked the baseband of those version..are not macthing with my phone's previsous version) OR should i go ahead and update via the carrier version section of the above guide then, will i lose my sim capability or will it remain the same and still i can use the sim of another country...

2) Should I just flash a unlocked version on the "unlocked" carrier verion of my phone but will it get bricked?

3)I tried using you DUN method but it didnt work for me..and how to enable VoLTE?

Really Sorry for the looong post but really desperate...

Oh and one more thing if AT&T is such a pain...should i just shift to verizon..my friends phone gets updated via the PC program...

Thanks a lot in advance
[Samsung Galaxy Note 8 Guides, News, & Discussion] DeathGrin13:
Ok I was finally able to download all the files only to realize I am on v4 bootloader... (smh). Can anyone guide me on how I can switch from sprint firmware to AT&T firmware while on v4 bootloader? I am at a loss and all the files in the guide are v3 bootloader.

i purchased note 8 950u xinfinity verizon locked . can i switch the firmware to sprint and unlock it
[Samsung Galaxy Note 8 Guides, News, & Discussion] DeathGrin13:
Flashing another firmware will not unlock your device. You will need to get the carrier to unlock it or go third-party route to get it unlocked. Once the phone is unlocked you can go through the carrier switching guide, then flash the sprint firmware and have it work on the sprint network.

I followed this you tube video to a t,ive tried to get in touch with the channel owner,but no luck. Im trying to get unbranded version so i can use my hotspot on an old unlimited plan.

Good luck, I'm in the same boat. I have an 800 dollar paper weight because I switched to verizon and sprint wont help. They tell me my phone is unlocked but it is not. I've been to every store in the area and spent hours on the phone. Still tells me to contact sprint to unlock, but once they find out I'm not a customer anymore they hang up, laugh or tell me they cant help.

So I went back to flashing the AT&T firmware on my SM-N950U1 which currently on 4CRE1 and I know there was updates released but my phone isn't able to get any updates and did enable the access point. anyone else running into this issue?

Update: actually, nvm about this as I found out that they only support their own devices for FOTAS so I'll have to update it myself.
[Samsung Galaxy Note 8 Guides, News, & Discussion] yedidi2006:
Hi,

A couple of questions but first some info. I have a unlocked t mobile note 8 sm-n950u using metropcs. I can't get any volte feature working. my current csc is TMB/XAA/TMB. My understanding is if I do a carrier switch and get it to say TMB/TMB/TMB everything will work.

1. I am on the June patch CRF3, can I downgrade to CRC2 and do the carrier switch?

2. Assuming the answer is yes, in the original post, I don't see the odin files to use for the carrier switch with the CRC2 firmware. Which do I use?

Thanks for putting together a very informative thread.

From Att to Generic

Hi, good day

If I do this procedure, would the Knox be tripped?

Thanks and best regards
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
Knox is not tripped by cross-flashing with the patched or modded ODIN.

Thanks!!, will try then and see if performance improves a bit

Best regards:)

[Samsung Galaxy Note 8 Guides, News, & Discussion] TamiaSky:
I have a T-Mobile version of Note 8 purchased from Samsung. T-Mobile unlocked it for me since it was purchased in full and I used it on Verizon with no issues (even received ota updates). My current setup shows SPR/SPR/TMB. I am currently on bootloader v4 (N950USQU4CRF3).

I am trying to have the sprint firmware. I don't see any v4 files and after searching the thread I am still at a loss. Any help is appreciated.

Main goal: VoLte does not work, keep getting random MMS error 225, internet super slow although I just got the service and on unlimited plan. Internet is slow in multiple zip codes despite them saying 4g LTE is covered in those zip codes. I would like to remedy these issues with sprint firmware. I am unrooted and would like to stay that way if possible.

What files would I need/Where would I go to get them? Do I even need to "carrier switch?"
[Samsung Galaxy Note 8 Guides, News, & Discussion] dwalkingdead:
Took my verizon note 8 to authorized Samsung repair center and they updated to the newest firmware (version 4 bootloader) from version 3. Now my Service provider SW ver. reads VZW/XAA/VZW instead of VZW/VZW/VZW (original). The phone works fine and KNOX is not tripped.

Does anyone know a way to get back to VZW/VZW/VZW?

Would flashing stock v4 firmware resolve this issue or would it trip KNOX?

I realize that my MMS doesn't work and the Mobile Network setting is not the same as Verizon.

Thanks in advance

I have a factory unlocked ATT Galaxy Note 8 SM-N950U1

I have a factory unlocked ATT Galaxy Note 8 SM-N950U1 with firmware baseband version SM950U1UES5CRF6 how was wanting to go to Verizon which one can I use there's only one I think could you point me in the right direction please I would appreciate it a lot
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
If you are running the U1 firmware, all you have to do is put in the Verizon SIM and the phone will convert on the next boot. U1 is an unlocked unbranded US firmware. If you are on AT&T firmware, you would be on a N950U firmware and not 950U1.
[Samsung Galaxy Note 8 Guides, News, & Discussion] jhoff80:
I was looking at the carrier-branded/carrier-specific unlocked versions for the N950U1 on T-Mobile and AT&T downloadable from Updato... and they're identical files according to hash checks. This is true for both the CRF6 versions of each, and the BRA5 ones. So if that's the case, what's carrier-specific about them? I know that the unlocked version will download some carrier-specific things based on the SIM card, but I'm just confused why the different carrier-specific section if they're the same though?
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
They contain a different carrier specific userdata.
[Samsung Galaxy Note 8 Guides, News, & Discussion] jhoff80:
Yeah, I was expecting a different CSC in each file, but both the overarching ZIP and the CSC file (and all others) in each zip had identical hashes, hence my confusion.
[Samsung Galaxy Note 8 Guides, News, & Discussion] rkamhaz:
Hi I have a question. I have an att note 8 and was wondering could I do this and flash to "unlocked" firmware and root my phone? I have already unlocked it so that's not why I want to flash the unlocked firmware. I want to know is it possible to flash and root? Thank you!

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!

Hi folks, thank you to BlueFox for all of your hard work. I haven't flashed a Android phone in years. Confession, i was a flashaholic back in the day.

I have a Samsung US Note 8 Unlocked bought direct from Samsung.com several months ago.

I would like to flash the full T-Mobile ROM and bloatware. Why? I am fully immersed in the T-Mobile DiGITS worldand would prefer to use the native Samsung texting and calling app's as they natively support DiGITS. I am not a fan of the DiGIT app.

I have tried many different combos of flashing this in searching through this thread. I simply cannot successfully flash it. I get a write error on every combo and every attempt. In short, help!

The current software on my US Unlocked Note8 is:

Baseband Version: N950U1UES5CRF6

Build Number: N16NW.N950U1UES5CRF6

Can I do what I am trying to do?

Thanks for any help you can provide.

[MENTION=292009]kregar[/MENTION]

You cannot flash firmware with lower bootloader version. As your N8 currently has BL V5 ( N950U1UES5CRF6), you can only flash FW with BL V5 or higher.

Try able to flash TMO's latest update (N950USQU5CRG7). Download via SAMFIRM, Sammobile.com or other...
[Samsung Galaxy Note 8 Guides, News, & Discussion] kregar:
Thank you OnnoJ.

I wasn't sure where the Bootloader version was signaled. I'll hunt for that.

Again, thank you.

[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
Yes, if you factory wipe the device before flashing, and you will get OTA updates for the firmware you are on based on that firmware version. U1 firmware gets U1 OTA's, T-Mobile firmware gets TMB OTA's, etc.

That worked like a champ! Thank you so much! DiGiTS works like it should and its just like having a T-MO Note.

Last question, can I re-do this with any carrier rom or Samsung US Unlocked rom like it was? As long as it is Bootloader 5 or later?

Thanks again,

What a HUGE help.

I messed up. Flashed unlocked to AT&T to get use of wifi calling. Everything was fine. Then I realized that I wasn't getting OTA updates and someone said call AT&T and give them my current imei to have it updated on the system. Now wifi calling is disabled.

They said because I didn't purchase it directly from AT&T, I can't use wifi calling. I told them I'm on AT&T software. They said it doesn't matter since it was purchased from Samsung.

On a side note, anyone got a link for the August AT&T security update? I can't seem to find it. I'm on CRF6
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
OTA's do not come from the carriers! OTA's are also rolled out in waves. If you don't get an update right away, be patient. It will eventually show up. You could have manually flashed it and kept your WiFi Calling working.
[Samsung Galaxy Note 8 Guides, News, & Discussion] 10pmStalker:
I didn't think wifi calling would be disabled since it's still AT&T firmware. I wasn't getting OTA updates. Latest security update was from April before I flashed the July one recently
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
A factor reset and reflash of the firmware or manually updating via a flash after a factory reset would have more than likely solved your issue. Never flash using the HOME_CSC. To get AT&T to restore your WiFi Calling, you are going to need to put your SIM in a AT&T purchased device that supports WiFi Calling, and more than likely have to call them to re-enable WiFi Calling for your number. Once it's done and you are off the phone with them. Wait a couple of minutes and then put your SIM back in your S9 Plus.
[Samsung Galaxy Note 8 Guides, News, & Discussion] 10pmStalker:
Can I factory reset and flash the same firmware im currently on or is that not possible? I just recently updated to CRF6 with odin
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
Yes. that is one of the very few exceptions. If you still have issues after that with your updates, try redownloading the firmware from a different source.
[Samsung Galaxy Note 8 Guides, News, & Discussion] 10pmStalker:
Thanks, will give it a shot. I contacted AT&T and told them I need to update my imei, gave them my old Note 7 imei and I'm able to enable wifi calling again.

Sorry if these are dumb questions. But are there no stock MVNO copies of the firmware? I have an unlocked tmobile note 8 that I've been using on metro pcs. But with the latest tmobile updates theyve deactivated wifi calling and volte when a non tmobile sim is used.
