Unlocked s8+ to VZW

Sorry if this is dumb, I have an unlocked s8+ from bestbuy (g955u1) , I want to have all verizons features on my phone, should I install the firmware for a g955u? on updato there's one with the product code of LRA but on Sam's there's one with the VZW product code? what's the difference and which would be right to get all the verizon features? :confused: Thanks for any advice!
[Samsung Galaxy S8+ Guides, News, & Discussion] AxlxA:
I got my phone. I am gonna flash the AT&T rom onto the 955U1 unlocked phone. In odin, I am unable to select UMS for the userdata... is that okay? Can I Flash att rom without the UMS?

Update: Bit the bullet. It worked without the UMS. So like mike said, the phone when first powered on with AT&T sim automatically set CSC code to AT&T. So once I figured that out, I just went with flashing Standard Firmware instructions and it worked smoothly. Now i got all the AT&T bloat back but I ALSO GET WIFI CALLING! I work in zero reception some times and I need that wifi calling feature.
[Samsung Galaxy S8+ Guides, News, & Discussion] SemperSyd:
?

Did you install a 955U version then? I was unaware that there was any carrier specific versions for the 955U1? Was thinking this may answer my question, I need the use of VZW wifi calling too in my area. Thanks!
[Samsung Galaxy S8+ Guides, News, & Discussion] AxlxA:
The U1 phone came with 955U1 firmware(unlocked). It didn't work with any of the AT&T features like wifi calling, VoLTE, Video calling(i've never gotten this to work even on my legit S7edge AT&T variant).

So I installed the rom that mike linked to... which is 955U AT&T version.

For your VZW -

http://updato.com/firmware-archive-select-model?record=090F4262517211E7963AFA163EE8F90B (june update)

http://updato.com/firmware-archive-select-model?record=BFBEC928390911E7963AFA163EE8F90B (may update)

http://updato.com/firmware-archive-select-model?record=4AC3AD4726D511E7963AFA163EE8F90B (April initial release)

I think one of the update takes away bixby remapping function or something... just off top of my head.
[Samsung Galaxy S8+ Guides, News, & Discussion] Mike15678:
Thanks for your input, I'll shout you out.
[Samsung Galaxy S8+ Guides, News, & Discussion] Mike15678:
Use the one that is "VZW". Not the one that is "LRA".
[Samsung Galaxy S8+ Guides, News, & Discussion] Sheon849:
I went with the unlocked firmware and it's a hell of a lot better.

Is this the most recent unlocked software update? Will we still get OTA updates?

I did notice even after flashing the stock firmware my phone still try to download some Sprint crap even though I unlocked it and am using ATT now. But I blocked it with package disabled pro.

Even though it was trying to download something with Spint ODAM it failed.
[Samsung Galaxy S8+ Guides, News, & Discussion] Mike15678:
If you flashed the unlocked firmware that was released on June 12, you should be running the latest. And yes, you'll continue receiving OTA updates, until Samsung ends support for the S8 and S8+.
[Samsung Galaxy S8+ Guides, News, & Discussion] Mike15678:
Did you first change your CSC by following the "Changing Carriers" section? You could have changed the CSC to "ATT" or "XAA".
[Samsung Galaxy S8+ Guides, News, & Discussion] Sheon849:
I am on G955U1UEU1AQE3

Thanks for your awesome guide too.
[Samsung Galaxy S8+ Guides, News, & Discussion] Mike15678:
No problem.
[Samsung Galaxy S8+ Guides, News, & Discussion] Sheon849:
No I didn't do that at first I did try the att rom but I didn't like it so I flashed unlocked rom. It's working perfectly fine now. I think the carrier is still set to sprint though. I wonder if I'll have any benefit to getting ATT.

When I flashed your ATT rom it didn't seem to get all the ATT apps. I didn't even get a att boot logo. And it only gave me 1 ATT app.
[Samsung Galaxy S8+ Guides, News, & Discussion] Mike15678:
There is a "USERDATA" file in the AT&T firmware. You have to follow the "Prerequisites for Anything You Decide to do in this guide" section in order to make the "UMS" box appear. You flashed incorrectly if you didn't include the "USERDATA" file.
[Samsung Galaxy S8+ Guides, News, & Discussion] Mike15678:
Did you flash the "USERDATA" file in addition to the other ones that were required?

I'm curious how stuff works sorry I'm going off topic but how does the phone apply a csc code in recovery
[Samsung Galaxy S8+ Guides, News, & Discussion] BlueFox721:
The csc info in mps_code.dat is reflected to specified features, installing apps and settings from given folders and files from parameters specified in feature coded within buildprop and efs setting guidlines...I don't know specifics...I haven't really looked too deep into it...you got me thinking now...
[Samsung Galaxy S8+ Guides, News, & Discussion] xdanilva:
I've gone into cache.img.ext4 inside CSC and it unzips sec_omc.zip into a temp dir and it copies the folder corresponding to your csc code somewhere. I'm just wondering where the script that does that is...

Would you say i was lying if i said it lasted about a year till it finally gave out . This is includin runnin multiple apps/games/music/dls/n having it run close to 24 hours each day . It was unexpected that it had to go out so sudden. I just had music playin, nothin else n then the music just stopped. Thinking that it possibly died but there was no signs of power when i connected the charger so i knew, then n there its time has come. I'd say it did amazing for a year especially running a rom i found which i am regretting that i didnt know about the forums here at the time cause you guys are the greatest help when it comes down to it. Wish us luck cause we may be able to dump files from another s8+ to the dead s8+ this weekend

Help - after T-mobile software update, lost my wi-fi calling...

Help - after T-mobile software update, lost my wi-fi calling...

(I posted this in the Tmobile q&a section but maybe you guys can help since I used this thread to change my Verizon phone to Tmobile so I could use it on MetroPCS).

Hi all,

I got the notification to update this morning. Now, on the latest G955USQU2BQK5. Previously everything worked flawlessly. Now after the upate, I no longer have wi-fi calling. It's just completely disappeared as a setting/option.

background - bought this as an unlocked S8+ Verizon version from Swappa. I'm on metropcs so I flashed the Tmobile stock firmware and carrier switched about 3 weeks ago when I got the device. Like I said, everything has been working flawlessly until the update this morning.

Any helps or suggestions? What do I do - I work in a place where I get no data/texts/calls so wi-fi calling makes my device work/function.

Screenshots. I circled an area in the about phone after the update this morning. I've never noticed what it was before but maybe it shouldn't say XAA/VZW?? Confused on why anything says XAA - i never flashed unlocked firmware and entered TMB when at the step in carrier switching...

Thanks for any guidance friends!
[Samsung Galaxy S8+ Guides, News, & Discussion] xdanilva:
You should try to do the carrier switching and switch over to XAA
[Samsung Galaxy S8+ Guides, News, & Discussion] jt1998:
Just carrier switching again - no firmware change?

Would carrier switching then cause me to lose the Tmobile wi-fi calling? That's what I'm trying to fix...sorry I'm still learning and kind of confused. Appreciate your help! :highfive:
[Samsung Galaxy S8+ Guides, News, & Discussion] xdanilva:
You should try it anyway and if it doesn't work you could try again and change your csc to tmb
[Samsung Galaxy S8+ Guides, News, & Discussion] jt1998:
OK. I'll try that when I get home today. To clarify - just carrier switch, no firmware change, right??
[Samsung Galaxy S8+ Guides, News, & Discussion] xdanilva:
Yes carrier switching only.

I think the T-Mobile features only require hardware.
[Samsung Galaxy S8+ Guides, News, & Discussion] jt1998:
It doesn't work.

Odin fails. I guess now that the firmware is updated, the carrier switching using the COMBINATION file in the AP slot isn't the correct one. UGH. I've attached a screenshot of my problem. This completely blows. I guess I have to sell this device and get a true tmobile version or wait to see if and updated tools to deal with this new firmware will come out....:crying:
[Samsung Galaxy S8+ Guides, News, & Discussion] xdanilva:
There's a updated factory binary

Thanks again for your patience and help.

Give me a bit im currently downloading the canadian AQK7 firmware. Then I'm going to extract the HOME_CSC file from it.

[Samsung Galaxy S8+ Guides, News, & Discussion] jt1998:
Thank you. Downloading now. I'll try the new HOME_CSC 1st.

If that doesn't work, when you say flash the BQK5 ODIN files, does that mean factory reset aka flash new firmware - like in the original post but using the BQK5 files?
[Samsung Galaxy S8+ Guides, News, & Discussion] xdanilva:
You can use the HOME_CSC in odin to preserve all your data.

So is it working. I can't test to see if it works or not rn. because I don't want to wipe my data.
[Samsung Galaxy S8+ Guides, News, & Discussion] jt1998:
phone is back to operational - thank you. Successfully carrier switched but still no wi-fi calling or VOLTE. I'm using a tmobile MVNO metropcs, and wifi calling always worked on every device I've used (always have been tmobile original devices though, unlike this verizon s8+). so don't know if its an s8+ issue b/c its a verizon device or b/c I don't have a tmobile sim....

Regardless thank you so much for your patience, your help, and getting my phone at least up and running. Thank you very much. I am so grateful for all your time and help. Seriously. Thank you!
[Samsung Galaxy S8+ Guides, News, & Discussion] xdanilva:
The tmobile wifi calling and volte requires specialized modem bands not present on the verizon model.
[Samsung Galaxy S8+ Guides, News, & Discussion] jt1998:
stinks that it worked prior to the update. UGH
[Samsung Galaxy S8+ Guides, News, & Discussion] jt1998:
Good morning. Another quick question. After the tmobile update my about phone settings were TMB/XAA/VZW. Then after you helped me last night it stayed the same. This morning, I tried carrier switch to metropcs (a tmobile MVNO that I'm on) and tmobile stock firmware and now this is showing XAA/XAA/VZW. Weird b/c metropcs 3 letter CSC code was TMK.

I'm trying to see if I can somehow get TMB/TMB/VZW. Do you have a suggestion on how to get there?

Thank you.
[Samsung Galaxy S8+ Guides, News, & Discussion] xdanilva:
Try to only change the csc code to tmb maybe..
[Samsung Galaxy S8+ Guides, News, & Discussion] cam30era:
FWIW: the hardware on all US snapdragon S8 and S8+'s are identical. Only the radio/modem (firmware) differes between carrier's.
[Samsung Galaxy S8+ Guides, News, & Discussion] jt1998:
I tried that last night. Then it ended up TMB/XAA/VZW. I dont' understand why the middle one is always XAA when I'm not intentionally using any unlocked firmware, files, etc. ....

I'm having some issues

I have the VZW model s8+ and decided today to change to the unlocked firmware to get rid of the Verizon bootlogo.

Installing the AQK2 xaa firmware worked no problem. after setting it up I went to update to BQK5 so I could flash the latest oreo.

However, In ODIN I flashed BL,AP,CP but no csc for BQK5, To keep my data intact. The flash worked, but on bootup I had tmobile apps, and I was unable to get a signal. The phone was thinking it was a tmobile device.

How do I solve this where I dont get tmobile bloat, the phone stays unlocked firmware with the bqk5 update and oreo after?
[Samsung Galaxy S8+ Guides, News, & Discussion] cam30era:
If I look at "unlocked" downloads, there's one for each major carrier, and one that's just unlocked. Are you sure you got the right one?
[Samsung Galaxy S8+ Guides, News, & Discussion] Nitefire77:
I'm pretty sure. It's running fine, it's when I try to update to BQK5 via Odin that's giving me issues. I did not flash a fax when going to BQK5 which I'm thinking might be my problem?
[Samsung Galaxy S8+ Guides, News, & Discussion] jt1998:

Using Xfinity Mobile, a few questions.

1. Will Knox be tripped?

2. Any Firmware official firmware can be flashed, right? (like these ones http://updato.com/firmware-archive-select-model?exact=1&q=SM-G955U)

3. What would the reason be to flash unlocked firmware, or do the steps for carrier switching?

4. If I do flash Unlocked Firmware, will I be eligible for the oreo betas? (When they're open again)

Sorry if I seem uneducated, as this is my first experience with much of this. Thanks!
[Samsung Galaxy S8+ Guides, News, & Discussion] cam30era:
1) No.

2) Yes.

3) To get rid of carrier bloat (and there is nearly none on the XM phones...). And if you flash unlocked firmware you may loose your VoLTE capability with XM.

4) Official Oreo beta program is full, but there is another thread for flashing unofficial leaked beta's.

[MENTION=7820902]xdanilva[/MENTION]

I know you kind of gave me some links to threads and downloads but havent had a chance to try yet - want to make sure I am doing things right

* I originally carrer switched from VZW to ATT, worked fine, than did it again with AQJC to XAA.

1. When I initially booted, it tried to a hard reset when I inserted sim

2. I then inserted Sprint sim it ran preconfigured for Sprint

3. When I took sim out and put ATT sim back it worked but now it does not , it sort of seems locked to Sprint (this was originally VZW but I got the IMEI in Sprint DMD by checking through TING BYOD checker)

4. I'm now on ZQKO with Sprint

Questions

5. Ever since I have S8+, any restoration of data seems highly irritating , it seems like hardly anything gets restored via Helium or Smart Switch , which makes me fret resetting phone? Any recommendations?

6. So it is necessary to do carrier switch again and reset data ? I am going to Europe soon and want some stability and the ability to swap sims.

7. Will the Sprint lock go away when I flash ?

8. You had linked me to AQEJ Canadian HOME_CSC, does it matter which one I use, should I use K7?

9. Are any or the OREO betas stable ? Which one you recommend?

10. If I do change back to XAA, steps are to boot without sim, disable autopreconfig, insert Sprint sim , reboot, enter manual APN info ?

Sorry I know I have a lot of questions, just want to get this right....
[Samsung Galaxy S8+ Guides, News, & Discussion] jt1998:
regarding 10, after carrier switch and firmware without SIM in, when i put the sim finally in, it got my APN info automatically. I guess if yours doesn't, yes manually enter it but it may find it correctly. Sorry don't know the other answers. Good luck.
[Samsung Galaxy S8+ Guides, News, & Discussion] xdanilva:
5.) If you want to update your phone to the latest oreo without losing data you can just flash BQK5 only with BL, AP, and CP then download the latest oreo ota

6.) I don't really know sorry

7.) What sprint lock? I think so.

8.) Yes you should use K7 because it has BL2 which is the current bootloader you're on.

9.) I would recommend at the moment ZQKS

10.) Take out your sim before doing anything and put it back in after you switch your CSC or if you want you can do that after going to oreo

Meinbach is on there
[Samsung Galaxy S8+ Guides, News, & Discussion] BlueFox721:
The binary file is for all carriers...there is not a separate one for T-Mobile...the most likely reason for your device showing XAA is that during the adb process, you entered XAA instead of TMB, else you may have flashed XAA csc files with the TMB files...for example, some users flash XAA complete and after boot to setup, they flash the TMB USERDATA and CSC files...to get carrier functions and some unlocked features...others mix the files during initial flash...Did you change CSC code to TMB or XAA at the adb step?

---------- Post added at 06:46 AM ---------- Previous post was at 06:13 AM ----------

If it worked prior, it should work now...the devices are all identical and the firmware turns on bands that are not on, for instance, if Verizon reports that a T-Mobile band is not available...the T-Mobile firmware enables it...it is not missing...in many cases, a bad firmware download can cause your issues...technically as long as you follow the guide and change the code to TMB you can flash any carrier, same version mind you, firmware (except the USERDATA file) due to the device being multi-CSC...If you want TMB, TMB,VZW...redownload the T-Mobile firmware, and follow the guide again...a few have had similar experiences on my thread:

You may need to perform a factory reset after flashing binary...

Well, definitely never typed in XAA in adb during any of the steps. After joining the telegram group, i received some advice. The key difference when I got the issue resolved was removing my Metropcs MVNO sim from my device. Then when I flashed the carrier switch and tmobile stock firmware, everything loaded up correctly. Then inserted my SIM back after the phone was setup and voila, all tmobile features were back and working. I was so stressed out not having tmobile wifi calling as I get zero signal at work otherwise. Thank you for your detailed reply and providing the above links! Much appreciated!! :good: :highfive:
