VZW to TMB

I too am trying to go from Verizon to Tmobile. I went through the whole EngBoot process and got the error at 32% when it was updating the tmb fw. The phone came back but then wanted to do an OTA which was from tmobile. I let it run and everything seems fine but I am hesitant because i'm not fond of errors in the flash process. Anyone else experience this? Phone seems fine. txt / wifi calling / updates etc all appear to be working.
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
you could have just used a special apn that bypasses the hotspot restriction lol i had cricket a month when i didnt have wifi just for this.. all i did was switch an apn, activate hotspot then switch apn back.. i used over 100gb on the hotspot lol

---------- Post added at 09:01 PM ---------- Previous post was at 08:58 PM ----------

right haha.. i was flashing over an hr yesterday nvr got eng method to work and simply flashed in ODIN and what do u kno lol
[Samsung Galaxy S8 Guides, News, & Discussion] moises93:
APN settings are disabled by carrier
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
yea but if you are on xaa/xaa/xxx you will have stock sammy settings which should allow you to select apn settings doesnt it??
[Samsung Galaxy S8 Guides, News, & Discussion] moises93:
Yeah now it let's me open apn settings. Defaults were already loaded.
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
gotcha.. so u couldnt edit but now on xaa xaa aio you can edit but dont need to lol
[Samsung Galaxy S8 Guides, News, & Discussion] moises93:
Yeah lol my issue was that when ever I tried to turn on tethering, it would go thru this provisioning of some sorts.

Hey! Im now on TMB/TMB/TMB, Can I flash the g950u1 firmware just with odin? Or I have to follow some steps before?
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
flash just in odin
[Samsung Galaxy S8 Guides, News, & Discussion] Skyrocket2Paradise:
Just to check after all the latest breakthroughs. What is the cleanest way to go from att/att/att to xaa/att/att? From what I have read that's what'll get you a debloated system and att features like hdvoice and wifi calling, correct?

Edit: Would flashing u1 with att userdata achieve that?
[Samsung Galaxy S8 Guides, News, & Discussion] Sheon849:
I tried all day and had no luck with this. I am using a8+ trying to go from t-mobile to verizon.

Always get permission denied.
[Samsung Galaxy S8 Guides, News, & Discussion] gqukyo:
Just realized it was uploaded under the S7 Edge... lol

I must have the worst luck. The U1 firmware doesn't work for me. I flashed all the files to my Vzw XAA/XAA/VZW and again when it's "updating" it errors out at 32% then and shows the recovery menu. I try to reboot and now it doesn't even work. I'm stuck on decrypting the phone after I enter in my passcode. Maybe that's the issue, I have set a passcode on device start up.
[Samsung Galaxy S8 Guides, News, & Discussion] fibrizo:
That might be it, but you may have to clear cache and format data from recovery.
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
go back to factory binary firmware and reset as itll remove any passcodes or frp and then from there straight to U1 firmware

---------- Post added at 02:28 AM ---------- Previous post was at 02:25 AM ----------

i did notice as well as i think i saw someone else post but I cannot install gear vr/oculos software?? anyone else have this problem?
[Samsung Galaxy S8 Guides, News, & Discussion] inneyeseakay:
FWIW, mine errored out every time I flashed after changing the mps_code, but when it booted to recovery, I did factory reset, then rebooted and it came up with the new carrier with no issues.

The passcode to boot is likely causing all your problems.
[Samsung Galaxy S8 Guides, News, & Discussion] gqukyo:
Tried that but it just put me back to the XAA/XAA/VZW state.

Going to try that now.

My factory reset just got me back to XAA/XAA/VZW so doesn't look like flash to U1 worked. Going to try what elliwigy suggested.
[Samsung Galaxy S8 Guides, News, & Discussion] Quickvic30:
I'll try flashing just user data in the ums slot and report back with the results.
[Samsung Galaxy S8 Guides, News, & Discussion] gqukyo:
I think I'm getting mixed up with the all the different firmware I'm downloading. Which is the U1 firmware? Is this the one w/ the file name "G950U1UEU1AQDC_7.0_ALL_XAA" in 7zip?

Assuming that's the U1 file for unlocked US S8's, it does work and does get past the 32% updating. The model # is now SM-G950U1. However, now I have XAA//VZW. Lol I'm completely missing the middle letters. Also, I'm on MintSim which uses Tmo so I don't know why I see a Sprint OMADM checking device status notification... lol I do not have carrier bloat whatsoever so that's great. Since I'm still seeing VZW, I booted to download mode and sure enough, the carrier still shows VZW. Haven't tried Samsung Pay yet but not sure I want/need to until I figure out how to complete get rid of the VZW designation...
[Samsung Galaxy S8 Guides, News, & Discussion] fibrizo:
Yes that's it.
[Samsung Galaxy S8 Guides, News, & Discussion] KevnRobles:
Could you also post whether or not video calling works? I know it probably won't but I would appreciate confirmation.
[Samsung Galaxy S8 Guides, News, & Discussion] Quickvic30:
Alright so it wipes the phone so beware of that! I have all ATT features but haven't tried video calling but it is enabled along with Wi-Fi calling. It's almost bloat free, it installs a couple att apps but they can be uninstalled along with all the Google apps.

EDIT: Returns phone to att/att/att. Model # stills shows 955U1

EDIT2: Wi-Fi Tethering works on unlimited ATT plan!
[Samsung Galaxy S8 Guides, News, & Discussion] gqukyo:
So I tried flashing the combination firmware, doing a factory reset from there and then flashing U1. Doing so I'm still at XAA//VZW with VZW showing up as the carrier in download mode. Could be that I'm not actually using a proper carrier sim. Just installed a brand new Tmo sim I saved up (guess for occasions like this lol). Inserted it and it said it'll reboot and set up for the carrier.
[Samsung Galaxy S8 Guides, News, & Discussion] KevnRobles:
If you don't mind could you check the video calling? And do you retain download booster? Thanks in advance

Edit: thanks for the info you've already provided lol. I'm hoping to figure this out and post in the AT&T S8 forum so it's easier for other. (Unless of course you want to do that.)
[Samsung Galaxy S8 Guides, News, & Discussion] Quickvic30:
Oh no problem at all! You can go ahead and post it just remember to give a little credit to the brave souls flashing this stuff lol.

Where is download booster located? I never use wifi.

I don't think anyone else I could call right now has video calling.
[Samsung Galaxy S8 Guides, News, & Discussion] gqukyo:
So the *# codes don't work in dialer so it seems even though I flashed the U1 firmware, I'm still somehow stuck w/ VZW limitations. Don't really care too much at this point as my only concern right now is to be able to receive OTA updates from Samsung and the device registering when I check for updates the very first time eases my concerns a tiny bit. Still gotta wait until there's an actual update from them to be sure. Lol
[Samsung Galaxy S8 Guides, News, & Discussion] KevnRobles:
Yeah I'll be sure to give credit :)

Settings > connections > more

Download booster should be there. I can pm you my number if you want to try it. I'm currently on a stock att s8
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
so no one else having issues installing gear vr?
[Samsung Galaxy S8 Guides, News, & Discussion] fibrizo:
I posted in another thread. Gear VR doesn't want to install on the U1 rom for some reason. I can't find a work around.
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
ive tried everything from safe mode, vpn, wifi and mobile data, clearing caches etc. with no luck.. i really dont want to reflash to vzw garbage lol
[Samsung Galaxy S8 Guides, News, & Discussion] fibrizo:
To be honest it sounds like you're flashing the wrong setup. I have a VZW device and when I flash all the above from the U1 rom it doesn't even show me XAA//VZW etc. It will still show it on the download screen as VZW however. I did see the XAA//VZW etc when I flashed different combinations of BL/AP/CSC/CP trying to get Gear VR to work, ie AP from the VZW G950U rom with the BL/CSC/CP from the U1 rom. I am actuallty running a project Fi sim usually, so that's not the issue likely. It seems like somehow you have data left over from previous flashes, maybe wipe data/cache from recovery, then flash BL/AP/CSC/CP from the U1 rom again?

---------- Post added at 12:17 AM ---------- Previous post was at 12:15 AM ----------

I know. I tried sideloading etc, I've tried combinations of CSC, AP, BL etc (which leads to some very odd results where I get all the bloatware of every carrier) But the cleanest thing I can do seems to be flashing VZW rom and not flashing user data or home CSC, while leaving the code to be XAA. Question is if I should just live without Gear VR for now or wait for a fix? Or run with XAA/XAA/VZW from VZW rom.
[Samsung Galaxy S8 Guides, News, & Discussion] Quickvic30:
I didn't see download booster in the options but then again I haven't even turned wifi on yet, no wifi access around. Yeah shoot me a pm we'll give it a shot.
[Samsung Galaxy S8 Guides, News, & Discussion] gqukyo:
Yup already did factory reset multiple times. I never mixed different files from different firmware. I'm in the same place as you now. There were others who said their carrier no longer showed what it was originally so that had me concerned but since you're seeing the same then I'm good. However did you try the *# codes in dialer? If that works for you then that's something different than my setup
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
its,actually under connections, more connection settings then download booster if you are on U1 firmware/settings
[Samsung Galaxy S8 Guides, News, & Discussion] Quickvic30:
I didn't see it in the options.
[Samsung Galaxy S8 Guides, News, & Discussion] fibrizo:
No the dialer codes never worked for me unless I was on the XAC rom.
[Samsung Galaxy S8 Guides, News, & Discussion] guaneet:
Cool feature I found using the unlocked firmware was Samsung neural keyboard

It actually works pretty damn well compared to stock and gboard
[Samsung Galaxy S8 Guides, News, & Discussion] Psyscope:
Anyone know if wifi calling is working?
[Samsung Galaxy S8 Guides, News, & Discussion] jaypr9:
And I thought I was going crazy. I just installed the U1 rom also because I didnt want any ATT bloatware. Everything looked great until I tried to reinstall gear vr and it just hangs at network error. Tried a bunch of things too, clearing cache, trying without sim card. Nothing... I really didnt want to reflash the original att rom.

Fwiw I dont have that info in about phone where it shows att/att/att. Need a workaround for this
[Samsung Galaxy S8 Guides, News, & Discussion] fibrizo:
I ran into a bunch of issues this am, my phone wouldn't take a new firmware and the factory data reset did nothing. Would sometimes error out at 32% etc and then eventually said Model dismatch and would fail. It turns out I needed to use a different modifed Odin, the comsey one seems to not work all of a sudden for me.
[Samsung Galaxy S8 Guides, News, & Discussion] jaypr9:
Are you trying to flash back to the original att firmware beacause gear vr isnt working? If so what are the steps to do that?
[Samsung Galaxy S8 Guides, News, & Discussion] fibrizo:
I have a VZW device, but the process is the same. If you changed your mps_code.dat, then flash an engineering bootloader and change the code back to ATT in your case. Then Odin flash the ATT BL, AP, home CSC, CP etc back on and it should be stock after a wipe.

I personally set mine to XAA again and just did Stock VZW BL,AP,CSC (not home) and CP without anything else to end up with XAA/XAA/VZW without bloat and gear VR works agian.
[Samsung Galaxy S8 Guides, News, & Discussion] cheher:
does samsung cloud work??
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
how do you get the code to change? i constantly get permission denied
[Samsung Galaxy S8 Guides, News, & Discussion] Quickvic30:
Even in combination/binary software you get permission denied?
[Samsung Galaxy S8 Guides, News, & Discussion] :
Did anyone have been able to remove simlock with this method?
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
yep

---------- Post added at 10:15 PM ---------- Previous post was at 10:14 PM ----------

no.. it does not magically sim unlock the phone..
[Samsung Galaxy S8 Guides, News, & Discussion] Quickvic30:
Mine is still sim locked, tried a T-Mobile SIM today and it prompted for a unlock code.

That's really weird, OEM unlocking is enabled? Is ADB connected and working for other commands?
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
yep and yep.. ive tried multople eng boots, combo firmwares, different bases such as vzw, xaa, xac etc. and probably flashed various things for hours and perm denied every time
[Samsung Galaxy S8 Guides, News, & Discussion] fibrizo:
Not sure then. I just followed the first post on this thread, (the one mweinbach wrote out) and it gave me rwx for the mps code.dat file
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
who knows.. what i do know is im not the only one haha i gave up trying
[Samsung Galaxy S8 Guides, News, & Discussion] Quickvic30:
Your on a VZW device originally? If so seems like they're touchy due to the CDMA and always being carrier unlocked. Have you tried re-partition with pit file?
[Samsung Galaxy S8 Guides, News, & Discussion] Shuthefrontdoor:
Keep us updated please! , But do know that att has to do something on their side also for you to have volte, they have to manually change ur imei to an att s8 imei #, I find chat through app or website works best.
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
yes and yes tried that lol.. either way i gave up trying and its just as easy to use a disabler or go to xaa/xaa/vzw for the same effect lol or go to G955U1

i cureently went back to full vzw/vzw/vzw
[Samsung Galaxy S8 Guides, News, & Discussion] Quickvic30:
If you keep reading a little further I posted the results. To sum it up you get all the att features minus Download booster. I do have video calling, wifi calling, and volte HD voice ect. Phone is still model number 955U1 but it does also show att/att/att further down in SW version. Today I flashed the XAC modem and it's working great and seems to have a little better reception for my location.
[Samsung Galaxy S8 Guides, News, & Discussion] Skyrocket2Paradise:
Awesome!

You also mentioned the tethering check doesn't exist right? So when you enable tethering it doesn't have that pop up to confirm with att it just enables. Is there an ATT text in the status bar when you don't have any notifications (could check the notification pull down too)? This might be the best route for att users. I wonder what happens when an update is pushed.
[Samsung Galaxy S8 Guides, News, & Discussion] Quickvic30:
Correct, wifi tethering works there is no provisioning check and I'm on the unlimited data plan with att. It does say att in in the status bar and in the pulldown shade at the bottom. You also have ATT data icon vs the generic no carrier data icons, I actually like the plain old LTE icon better personally.
[Samsung Galaxy S8 Guides, News, & Discussion] raduque:
I have it on Verizon.

Wifi calling works if you are on T-Mobile, but only VoLTE works on Verizon, and I don't think you get any of that on AT&T.
[Samsung Galaxy S8 Guides, News, & Discussion] inneyeseakay:
If I'm on att/att/***, volte works...

If I'm on ***/att/***, volte works... Although I haven't found a way to stay in this without having eng boot.

If I'm on anything else, (xaa/xaa/***, g950u1, etc)... Volte doesn't work. So I'm provisioned correctly with at&t. Volte just doesn't work on at&t without at&t's CSC

I'm wondering if someone had the CSC file for the at&t rom... If we could flash it with g950u1 and have working volte.
[Samsung Galaxy S8 Guides, News, & Discussion] Shuthefrontdoor:
Upon further reading it just seems the same for you, still with att bloat and stuff, just to understand what exactly did change for you besides tethering, im wondering if Carrier IQ is still on your phone, you no longer have att boot screen? Thanks for the info
[Samsung Galaxy S8 Guides, News, & Discussion] inneyeseakay:
Where did you get the att firmware?
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
all the stock roms have multi csc..so they contain all the csc for every carrier
[Samsung Galaxy S8 Guides, News, & Discussion] Quickvic30:
I flashed the U1 firmware then reboot and set up then I flashed att user data in the ums slot all by itself and volte, video calling and the option for wifi calling is there but I haven't tried it yet.
[Samsung Galaxy S8 Guides, News, & Discussion] inneyeseakay:
Whered you get the att ums? While I'd prefer the non-branded data icons, volte is worth it.

Does att have an LTE+ icon, or does it just does the same icon for both LTE and LTE+?

With g950u1 firmware, this is the first time I've ever seen LTE+.
[Samsung Galaxy S8 Guides, News, & Discussion] Quickvic30:
I have a 955 and theres a couple firmware threads in the ATT 955 section. I did look for 950 firmware for att but couldn't find anything which is pretty odd. I bet you could use s8+ user data on your​ s8.
[Samsung Galaxy S8 Guides, News, & Discussion] inneyeseakay:
Guess it won't hurt to try... Will post back results.
[Samsung Galaxy S8 Guides, News, & Discussion] raduque:
So for the GearVR not working thing... is it maybe because the 95xU1 isn't actually technically released yet and so the update server is rejecting the phone's model number?

So maybe it'll start working tomorrow?
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
possibility
[Samsung Galaxy S8 Guides, News, & Discussion] raduque:
I'm not worrying about it too much though, because I still have two S7 Edges to use. I'll try it again on the first.
[Samsung Galaxy S8 Guides, News, & Discussion] umairaslam25:
Non-US Carrier

I have a carrier locked G955U TMB. Haven't tried flashing anything so TMB/TMB/TMB.

Is it possible to switch to a non-US carrier by using a particular CSC Value or do I need to get it sim unlocked?

Actually I am overseas and I did't get it temporary unlocked before leaving. I thought I can do it from anywhere but the t-mobile unlock app needs a data connection for temporary unlock and I don't have data roaming. The permanent unlock can be done using wifi but that needs the phone to be paid off which I dont wanna do right now as it will kill the BOGO $750 prepaid card deal.

Really appreciate the support.

I have a Sprint S8, with a domestic SIM unlock provided by Sprint, and flashing the device using the modified ODIN and the G950U1 firmware linked on the first post allows me to use a Verizon SIM without any issue. SMS works, VoLTE works, and now I have a carrier unlocked S8 which recognizes any SIM and updates accordingly.

I flashed the att user data just to see what options it would reveal but I plan on flashing back to pure XAA as it seems to have better signal and is quite a bit faster it seems than after flashing the user. I don't use all the fancy feature anyways.
