Sorry if this has been asked before. I was able to follow this guide to change my CSC in the software from VZW to TMB and install the full TMB firmware. How do I change the CSC product code in the bootloader itself to go from VZW to TMB? That way I can have a full 100% official T-Mobile device.
[Samsung Galaxy Note 8 Guides, News, & Discussion] kbonnel:
Thanks for the feedback. I did check the "About Phone / Software Information / Service provider SW ver" phone and it does show TMB/TMB/VZW so I assume it worked correctly? (if that is what you are referring too?
[Samsung Galaxy Note 8 Guides, News, & Discussion] qc777y:
MrMike,

I actually later found the reasons for my lack of success. Odin kept failing before completing "Setup Connection", and I assumed this to be because the bootloader U5 was preventing Odin from successfully connecting. Samsung USB drivers were installed, and the referenced COM port in Odin was blue. After spending at least 30 hours of the weekend trying various combinations of firmwares, combination files, and everything imaginable, I found that my problem was usb3 ports. I tried two case and 3 motherboard USB3 ports with no successful results. I tried a case USB2 port and immediately was able to successfully flash firmware. I shed a single tear and went to sleep at 4AM yesterday morning.

Will this trip Knox or trip the efuse? Like the note 5? Also my phone is unlocked I'm using a straight talk sim with this sprint branded phone, will flashing the tmobile firmware on this sprint note 8 knockout my unlocked status?

Does anyone have a mirror for T-Mobile? (Latest CSC - N950U1OYM5CRL2) "(TMB) T-Mobile - N950U1UEU1AQH9/AQI5/BQK1/BQL2/BRA5"

I've tried Sam and Updato but both eventually stop working. The latter reached 25% after 5hrs before hanging (and later failed after pause & resume). Mega, AFH, and Drive are the only hosts that work properly for me.

One more question which combination / home file do I use? I'm a little bit crusty with this!
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
Don't use the HOME_CSC if you are flashing to a different firmware. You need to use the other CSC file.

V5 Bootloader Flash

My Note 8 has model number n950u and baseband version N950USQU5CRIA. I believe this is T-mobile firmware running version 5 bootloader. I am just hoping someone can confirm I am following the correct steps with the correct files to flash to unlocked firmware. I am planning on following the steps outlined in the original post 4 for flashing unlocked firmware. I will flash firmware version N950U1UES5CSA1 and use Odin3_v3.13.1_3B_PatcheD. Is this the correct firmware and Odin version? I would really appreciate any help; thanks :)!

As far as downloading the firmware goes, I see lists on websites like sammobile where the same PDA is listed multiple times under multiple carriers. Do i need to download one that says it is XAA specifically? What is the difference between these different firmwares with the same PDA? My main goal is to unlock all the bands on my phone, so do I need to use XAA version specifically? Thanks again.

edit: My main goal was to allow my phone to access all bands. I thought that using the T-mobile firmware, I would not be able to access band 7, since it is not included in the tech specs for the T-mobile note 8. However I disabled all other LTE bands by dialing *#2263*. I then dialed *#0011* to confirm that my phone was connected on band 7. My phone still said LTE in the tray, and the internet connection worked. Does this mean an unlocked T-mobile phone can access all bands and I don't need to flash the firmware? I just bought it on ebay "UNLOCKED TO WORK WITH GSM AND CDMA CARRIERS", but it has T-mobile splash screen.

what csc file do i need to use it wont let me flash the BRA it fails

my build number is R16NW.N950USQS5CRL1

I'm trying to switch from sprint to tmobile

I really appreciate the help :)
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
You need to flash to the U1 build first, then to the TMB U! Do not yse the HOME_CSC when cross-flashing. Are you using the modded or patched ODIN? Have you enabled USB Debugging in Developer Options? Do you have the drivers for your device installed while it is in Download Mode? Makw surr you arw plugged into a USB port with the cable that came with your device that is a port that doesn't share, or try a USB 2.0 port.
[Samsung Galaxy Note 8 Guides, News, & Discussion] RewitZer:
Thank you for the info. I guess my USB cable is the culprit it's not an official cable and Odin by prince fails instantly. I am on the prowl for an official cable I will let you know what happens next
[Samsung Galaxy Note 8 Guides, News, & Discussion] Ace42:
It's for the best. Battery life and idle drain made a marketable difference (TMB to XAA). Lost 1-2% over night. No regrets.

Flashed SM-N950U1 firmware and unable to go back to SM-N950U

Please help me someone, my phone is currently stuck in Download mode since I am not able to successfully flash any sort of firmware whatsoever. I am coming from firmware version ZSAB for model SM-N950U1 which is the unlocked variant of the Note 8 (my phone is model SM-N950U for T-Mobile). Here is what happened:

I first flashed the CRL2 Oreo firmware (this was while I was on firmware DRL5 which is the Android Pie Beta for SM-N950U) for the SM-N950U1 model.

Then I flashed Android Pie firmware ZSAB for SM-N950U1. All of this worked just fine, but I didn't like some of the bugs I was experiencing so I tried to go back to firmware CRK1 which is Oreo for SM-N950U (I think). Kept getting Odin failures, so I tried using different versions of Odin along with CSC (instead of HOMECSC) but still nothing.

I have already tried wiping my data and cache partitions and even tried to go back to firmware ZSAB and DRL5 but same Odin failures.

Can anyone point me in the right direction please in order to go back to SM-950U Oreo firmware? Thank you so much.

Hi everybody, would need a little help for my Galaxy Note 8 Sprint variant that I have just unlock. I want to debloat it by flashing unlock carrier... I read all the tread about switching carrier, but I have a bootloader v5 (N950USQU5CRG7) and all the combination files and firmwares have v1, 2 and 3 so I dont know if I can do it...

My ultimate goal is to make my phone a canadian variant N950W. Is it possible?

Thanks!
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
Totally possible! You need to flash the W firmware with the v5 bootloader. The U1 firmware also works great up in Canada. Which ever firmware you decide on, you need to find the v5 bootloader version to successfully flash with the modded or patched ODIN.

Switch carrier Sprint to Canadian unlock for Galaxy Note 8

Okay ?, but what about combination files?? Do they need to be of the same bootloader version?

Thanks for the help!

---------- Post added at 02:49 PM ---------- Previous post was at 02:47 PM ----------

Do you mean that I can just flash Canadian firmware over the Sprint on without combination files? Sorry if it's not evident to me ?
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
Personally, I wouldn't use combination files unless your device is a F or DS Exynos model. If your device is a U or U1 firmware, you can flash the W firmware because the hardware is exactly the same. You will need to wipe the device thoughbduring flash by avoiding the HOME_CSC and using the other CSC. If you don't wipe, you won't get a complete conversion.

---------- Post added at 02:57 PM ---------- Previous post was at 02:51 PM ----------

What you need to do is flash to the U1 firmware with the v5 bootloader and use the CSC that wipes the device to ensure it converts properly. Then, skip the setup, re-enable Developer Optio s and USB Debugging and flash the W firmware through the modded or patched ODIN, just lime you did to get to the U1, ensuring you do not use the HOME_CSC but donuse the other CSC, which will wipe the device again. The device wiping makes sure you get a full conversion, includong available LTE bands, software, and can even take OTA's from that point on for the furmware you install.

Hey guys,

noob here, what does "switching carriers" accomplish? I have a TMO note 8, unlocked, used it with Xfinity and noticed that after a couple of power cycles, I have the Xfinity Mobile boot screen plus some other carrier specific apps asking to be downloaded. Is carrier switching similar?
[Samsung Galaxy Note 8 Guides, News, & Discussion] Milly7:
What firmware are you running? And carrier switching is flashing a different carriers specific firmware.

Hey I have a quick question. I am currently on 7.1.1. with firmware N950USQU1AQIA. Can I immediately flash XAA stock universal version 8.0 N950U1OYM5CRK1? Or do I need to flash another version before flashing this 8.0 version?
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
You can flash directly to the v5 bootloader XAA, if you wish. You can not flash backwards though when it comes to bootloader versions, so you will be limited to v5 bootloader firmwwre if you flash to the v5 bootloader 5CRK1 from your v1 bootloader 1AQIA.
[Samsung Galaxy Note 8 Guides, News, & Discussion] colemanation:
Oh ok. thanks for the quick reply. One last question. Whats the difference between Stock Universal Firmware and Unlocked Firmware?
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
I am not shre what you mean by stock iniversal firmware, but the U1 has a misconception of being the unlocked firmware when it has absolutely nothing to donwith the SIM status of the device. The U1 XAA is a non-carrier specific (generic) firmware that is compatible with US carriers service.

I have a T-Mobile Note 8, model is SM-N950U, purchased used Oct 2018. I paid an eBay unlock service so I can use it with my work AT&T plan, phone works fine but the OTA update always fails at 32% and so I am stuck on the July security patch. I thought it was because I'm on T-Mobile firmware, but with Oreo it has the AT&T boot logo and visual voicemail works so I'm at a loss.

Firmware version is N950USQU5CRG7

All I want is to be able to get Pie next month and for OTA updates to work again so I'm not stuck on ancient security patches.

Can I flash the PDA N950USQS5CRL1 and CSC N950UOYN5CRL1 Tmobile firmware from SAMMOBILE to fix OTA updates or should I be looking for AT&T firmware? I don't see an AT&T firmware listing on SAMMOBILE. Do I just use the USA (USC) version? That is all I see in Updato, or maybe the UI is just not as user friendly as SAMMOBILE.

Can I still use Odin3_v3.13.1_3B_PatcheD from the original post to flash?
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
Any complete stock firmware version will be able to take an OTA.

I'm sorry if the answers are already supplied, but I have some questions.

I have a VZW N950U, and want to flash U1 Software, and plan to use a VZW SIM.

-How do I activate carrier functions like WiFi calling, tethering, etc without adding carrier bloat? Can I avoid all bloat apps or will some still install?

-If I flash U1 Firmware, will I be able to take the U1 Pie update with built-in (settings menu) OTA?

-Will it still have Verizon boot screen?
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
Are the bootloader versions the same or is the one you are trying to flash neeer than what your device currently has? Did you enable USB Debugging in Developer Options? Are you using the modded or patched ODIN? Are you using the original USB cable that came with the device? Have you tried a USB 2 port?
[Samsung Galaxy Note 8 Guides, News, & Discussion] 10pmStalker:
I'm not sure about the bootloader thing. Using original cables, tried multiple ones. USB debugging is not on as I had to flash from DLR7 first. That did a factory reset. I've tried multiple Odin versions. I'll enable debugging and try again.
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
You keep keaving out the bootloader version by only posting the last 4 characters of the firmware. The bootloader version is the number before the last 4 characters.
[Samsung Galaxy Note 8 Guides, News, & Discussion] 10pmStalker:
Sorry about that. I'm currently on N950USQS5CRK1
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
No worries. 5CRK1 has the version 5 bootloader. If you are flashing from that firmware, you must flash to another v5 bootloader firmware. Firmware with earlier versions of the bootloader can not be flashed to.
[Samsung Galaxy Note 8 Guides, News, & Discussion] 10pmStalker:

[Samsung Galaxy Note 8 Guides, News, & Discussion] Mr. Orange 645:
If you're on Verizon, you can absolutely flash the U1 firmware. It is universal and works for all carriers and is compatible with all N950U models. I recommend using the most recent U1 firmware 5CSA1, which can be quickly and reliably downloaded using the SamFirm tool.

You will not be able to activate WiFi Calling, VoLTE, or RCS messaging, as Verizon does not support those features on the U1 firmware.

You will still be able to use hotspot, though I'm not sure if it bypasses the Verizon check for a hotspot plan. I'm on T-Mo.

You will not have any carrier bloat, including the Verizon boot screen. That's the beauty of the U1 firmware.

Yes, if you are on the U1 firmware, you will receive OTAs, including the Pie update, when it is released.
[Samsung Galaxy Note 8 Guides, News, & Discussion] gregcapps:
Some carrier functions will work. Tethering, VoLte, but some like video calling, wifi calling will be gone. As it stands right now the U1 is still in beta for pie, but if you remain on u1 firmware, you'll get it when it officially releases. The boot screen will be the generic Samsung, no Verizon boot.

I want to use the OneUI beta official because I have finally started running into a few issues with DRL7 I dislike.
[Samsung Galaxy Note 8 Guides, News, & Discussion] Mr. Orange 645:
Sure. When it comes time, use SamFirm tool to download the current official firmware, then flash it with patched ODIN.

Or just send it in as is. Samsung won't care.

Cool. I am making sure I don't mess up my device or anything -- I download OTA updates manually and have messed around with my phone a lot but have never flashed the entire firmware.

I will be using the post that says this, I think it was the third. Moving from Carrier to Unlocked firmware:

So I'll use the Prince Comsy Odin, then get the files for the Unlocked (the "Verizon unlocked" if that's available) or the XAA?

I'm on Verizon.

Thanks so much.

---------- Post added at 08:06 PM ---------- Previous post was at 08:03 PM ----------

Oh, one more question, so sorry!!

If I am on the DRL7 OneUI beta on my Verizon Note 8, do I need to go use Odin to flash back to the CRK1 update I was on in December and then update to the latest and start? or can I just flash it? ALSO: Which Bootloader would I have?
[Samsung Galaxy Note 8 Guides, News, & Discussion] Mr. Orange 645:
No, not Prince Comsy ODIN. Patched ODIN 3.13.1_3B. You can find links for it here on XDA by searching.

If you're device was originally an unbranded Unlocked by Samsung model, then you will use SamFirm to download the XAA firmware. Model: SM-N950U1 and Region is XAA.

If instead it was purchased from Verizon and is a branded carrier model, you will use SamFirm to download the VZW firmware. Model: SM-N950U and Region is VZW.

You are bootloader 5.

You don't have to upgrade, downgrade, side grade, grade your driveway, or grade your homework. ODIN is used to flash full firmware. Just flash straight to the firmware you want, as long as it's bootloader v5.
[Samsung Galaxy Note 8 Guides, News, & Discussion] DarthDraz:
Awesome, I'm on Verizon and have been trying to figure this out. First time flashing anything.

I'll flash straight to that then.

[Samsung Galaxy Note 8 Guides, News, & Discussion] Mr. Orange 645:

[Samsung Galaxy Note 8 Guides, News, & Discussion] Flame Red:
I was hoping I might get some guidance here. I have tried searching and googling but no joy.

I have a N950F, yes exynos, running Dr. Keaton's fine ROM. I used to use [MENTION=5899304]Tkkg1994[/MENTION] fine CSC Selection Tool to flash the ATT CSC and that worked fine, but sadly that tool is no longer supported. It still works BTW - but the CSC it uses is a couple years old now.

Dr. Keaton used to supply the ATT CSC with his fine Oreo Roms but stopped supplying that CSC since he only had old ATT CSC.

So I tried downloading the U1 firmware from Sammy and flash it via Prince Odin, but it does not seem to let me as I think it knows it was meant for SnapDragon and what I have is exynos.

I am not a developer but hoping someone might be able to point me to a procedure to extract the latest /system/OMC/ATT and other necessary bits from the U1 ROM so I can plop it on my N950F without bricking it.

Thanks in advance!
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
The U1 is for North American hardware only! You might be able to extract the CSC and swap that out with the one in the ROM you are using, but the firmware base is for SnapDragon devices. If you successfully flash a U1 image to an Exynos device, your device will be bricked!
[Samsung Galaxy Note 8 Guides, News, & Discussion] Flame Red:
Thank you for the reply. Exactly. I cannot seem to figure out how to extract the CSC bits from the U1 version. I was hoping there was a well document procedure to do that. Obviously, someone has figured that out, at least for Oreo and the results work properly on exynos. Seems like the old Oreo ones I am currently using (from the CSC Selection Tool) still work on Pie, they are just very old.
[Samsung Galaxy Note 8 Guides, News, & Discussion] Ace42:
Inside of the FW package you'll see Home_CSC and CSC_OYM. Remove these from the U1 or carrier zips for the N950U. I have only the files for CSA1 (XAA U1).

Oh man! I am at work -- I have a PC here but it is restricted on what I can install, SamFirm won't work here.

[Samsung Galaxy Note 8 Guides, News, & Discussion] Flame Red:
Thank you for your reply. I downloaded N950U1UES5CSA1_N950U1OYM5CSA1_ATT.zip from Sammy. I see the HOME_CSC_OYM_... and CSC_OYM_... in there.

Forgive the amateur question :)

When I open those with WINRAR, I see in there cache.img.ext4.lz4 in both. I see that 7Zip can open those files. When 7Zip opens it, there are a number of directories in cache.img.ext4.lz4, but system\HWRDB\data\ looks interesting as it includes hwr_de_DE.dat. But I cannot seem to open that or extract it. Am I looking at the wrong contents?
[Samsung Galaxy Note 8 Guides, News, & Discussion] jcsww:
You extract the main file, which will give you a BL, CP, AP, 2 CSC's, and a Userdata. The HOME_CSC preserves data, which is not recommended for cross-flashing or reverting to a previous firmware nevause you will be plagued with issues. If you are upgrading from an older AT&T firmware to the newer one, then it is fine to use the HOME_CSC. Otherwise, use the other one, which will wipe your device.

You use ODIN 3.13.3 to flash those files to thw device. You need the modded or patched ODIN for cross-flashing.
