So does anyone know the steps to get my ATT S8+ onto the unlocked U1 firmware, and have all calls working without immediately ending?? also having VOLTE/WIFI calling and video calling working?? Also VVMail would be good as well but not needed. Calls work on Canadian firmware without immediately ending, but as mentioned earlier there are no settings for wifi calling
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] jaypr9:
Have you tried flashing the att user data on to the Canadian firmware? I've done u1 firmware then flashed att userdata but that doesnt work for me, volte calls just end.

yes i just tried Flashing the Canadian Firmware again and after skipping through setup, flashed the USERDATA_ACG_G955USQU1AQD9_CL11131491_QB13157333_REV00_user_low_ship_MULTI_CERT.tar file in odins UMS slot and have a constant Unfortunately the Process.com.android.phone Has Stopped even after factory reset and clearing cache it still happens. Also happens when I flash Canadian firmware, then flash the older USERDATA_ATT_G955USQU1AQC9_CL10895874_QB12856072_REV00_user_low_ship_MULTI_CERT.tar file in UMS

any idea what I am doing wrong?? Should I flash USERDATA in another slot after Flashing the Canadian Firmware, or is there another combination im missing or something else??

Does either full unlocked fw have mobile hotspot that lets you draw off your regular data plan instead of the Wi-Fi hotspot that requires you to have home Wi-Fi network?
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] Shuthefrontdoor:
I read somewhere that someone claimed to have grandfather's unlimited plan which doesnt include tethering, and after flashing to u1 they are now able to tether
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] Billy06010:
Since no one seems to have an answer here's where I am now. I flashed last night the U1 firmware but replaced the CSC with the one from the AT&T Firmware. Now my phones Service provider SW ver. is ATT/ATT/ATT When flashed in that configuration you get the usual Samsung bloat and the Google bloat but no AT&T bloat. Most of the bloat you can disable or uninstall which works out good. WIFI calling and VOLTE are working and so is video calling. only thing missing is VVMail which i can live without. Also I'm not sure if updates will work or not. will have to try again once the U1 firmware has an update. Worst case scenario, backup with Samsung cloud and flash the new U1 update once available with the AT&T CSC file. Anyone want to chime in with an easier or better solution be my guest.

Also in the settings is Mobile Hotspot and USB Tethering
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] jcrompton:
is there any noticeable benefit yet?
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] Billy06010:
None really that I can see. It looks and feels just like stock AT&T. You loose the AT&T bloat, but also loose VVMail. So your probably better off stock and just using BK package disabler or package disabler pro and disabling all the junk you don't want.
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] jcrompton:
That makes sense

Do you know if there is a list floating around for " safe to disable " ?
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] Billy06010:
Not off the top of my head, i usuall just disable whatever I want. I'm sure there's a complete list somewhere on here. If not in any S8+ or S8 thread then maybe in an S7 or S7 edge thread. Sorry to not be more help.

The unlocked firmware and the Tmobile firmware will both let you tether no problem with the old grandfather unlimited plan. Been using it since the Note 4 just for that reason.

---------- Post added at 01:18 PM ---------- Previous post was at 01:15 PM ----------

In the unified S8+ forum there is a thread about what is safe to disable.

The main ones are the IQServices and a Qualcomm one. But I also get rid of most the AT&T stuff.
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] saadi107:
I installed the Canadian version on my AT&T S8+. Everything worked fine but I noticed that Samsung pay isn't an option anywhere in the phone. When I try downloading from the play store I get the message that "your device isn't compatible with this version".

Is this because I changed my firmware from att stock?
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] raze5115:
What if you have the new att unlimited choice data plan will the unlocked fws still let you use the hotspot to draw off the unlimited data plan?

Not sure how this will be effects I have never had that plan and have not looked into it.

Nope, I've tried all the suggestions here even tried att twice to see if they needed to do anything but nothing. I just flashed the stock att firmware and used an disabler to disable the bloat.

Fix mismatch firmware?

Has anyone successfully got these to read the same in all 3 places? In software update I have the middle build # mismatched and in SW version in settings I'm missing the middle build and other two don't match.

I flashed US unlocked over AT&T S8+ with home CSC. I haven't flashed anything else after. Not to worried about wifi calling or VOLTE just hoping to get updates OTA and not have to sideload.

If anyone successfully got U1AQDC across the board please tell me your steps. Also if anyone has been successful in going back to att/att/att after flashing US unlocked.

My phone was sim unlocked with code and a T-Mobile sim before flashing US unlocked and I am on the cricket network currently if this makes any difference.

If anyone did this with an S7 before, was the process the same, did you receive OTAs , did firmware mismatch, could you return to stock?

ANSWERS PLEASE :eek: it's driving me insane cause I know the next update is around the corner and want to be able to get it and future updates painlessly while I sleep at night lol.

Thanks in advance
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] y2jdmbfan:
Are you trying to get back to AT&T stock? I was able to after trying to go to US Unlocked with VoLTE from full AT&T. I even got the OTA AT&T update after I flashed back.
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] AndroiderM:
I'd prefer to stay on US unlocked and receive OTAs ideally but I would like to be able to go back to full AT&T stock. Did you just download the factory firmware and flash all slots in Odin or is there more to it?
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] dtomlin:
Non related, but what theme/font is that?
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] AndroiderM:
Bauhaus flip font from galaxy app store, theme is Toxic Blue from theme depot. Search xda for theme depot you'll find a link to there site and a Telegraph support group. Good themers there and updates.
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] y2jdmbfan:
Yeah, just downloaded the factory firmware and flashed whatever packages came in the zip in Odin.
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] AndroiderM:
Thanks+1

Imma wait till the new update is pushed to US unlocked devices and see what happens, if no OTAs I'll flash back and disable all the Bs.

I know I asked before but no details...

Hope did you replace the ATT CSC in the U1 firmware?

Do you now have the QE firmware update and still have ATT WiFi Calling and VoLTE? I don't use visual voicemail .... I use youmail
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] cnote74:
My phone says it's up to date though I'm on the May security release. Has anyone who got the update have AT&T in 2 slots of the service provider info? Mine has AT&T in all 3 slots but still the u1 firmware.
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] ShrekOpher:
Do we have the clean unlocked firmware to download anywhere?

Also I have a few questions. Does this completely wipe your phone?

Is there a way to do this without having to reset the phone up?

Can you enable the video calling and caller ID and still get the U1 updates via OTA?

Thanks

[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] AndroiderM:
Yes, I can confirm if you flash the US unlocked firmware with home CSC you will receive 955U1 updates via OTA. Idk If you flash the AT&T user data if you will get OTAs or not.

How did you get back on Stock AT&T? Help me!! I can flash AT&T firmware AQC9 but it won`t change anything still its XAA/XAA/ATT. I have unlock code but can`t use it. How to make ATT/ATT/ATT
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] Billy06010:
try flashing AT&T Userdata in AP Slot by itself and then let it reboot. Should have you on ATT/ATT/ATT. If that works then odin flash all 4 AT&T files
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] cnote74:

Well it looks like Samsung is keeping its promise. A full month ahead of carriers on there updates. That's crazy. I'll give it one more month, but come end if July is the Unlocked version gets the July security patch super fast definitely will jump ship to that firmware.
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] vg001:
Tried flashing at&t userdata in AP slot. Nothing changed, still XAA/XAA/ATT. I tried flashing CSC (not home csc) . After odin completed flashing and phone reboots and it will show me 'Installing system update' then in 32% It will get an error then it goes on recovery. In recovery "failed to mount data" rc = -1 omc binary download. something like this error
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] Billy06010:
2 more options for you

1. Try Flashing Userdata by itself in CSC slot

2. Flash the new G955U1 Firmware linked above, then try to go back to ATT from there
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] AndroiderM:
1)factory reset phone

2)remove sim and SD

3)use adb reboot bootloader

4)open Odin and load XAA firmware with home CSC

5)let phone boot and setup over wifi

6)power down

7)insert sim and boot

These are the steps I used to flash the XAA firmware in the OP and I received the unlocked OTA yesterday to the newest build and security patch. If this helps get anyone back to XAA or ATT. I haven't tried to go back to ATT but I am getting OTAs for XAA
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] dtomlin:
I flashed and set up. Then did the OTA to the new firmware. I just noticed I don't show Service Provider SW Version under about phone.
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] ShrekOpher:
Is it possible to go to the Unlocked firmware without having to re-setup your phone or does switching firmware versions require a complete wipe?
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] dtomlin:
That one I don't know. I always do a full wipe and restore with my samsung account.
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] Saythis:

[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] jason1332:
My experience.... I downloaded the full file from updato and used prince's Odin to flash all the files with home CSC and for some reason I still had all user data. Never wiped the phone at all. I can't say why but I was very happy to not have to restore! Can't really offer any more info but that was my experience. Now on XAA with June patch.

I did mine without SIM. Set up over Wi-Fi. Powered off, inserted SIM. Powered back on, then took the OTA. I think it had the service provider stuff before the OTA though. I've got strong data and texts and calls.
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] jaypr9:
If you flash u1 and nothing else you'll get no service provider info, thats what happened with me but I didn't have volte. I also flashed att userdata got att/att/att but also couldn't get volte to work. Calls would just end immediately.
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] dtomlin:

You need to fool them with giving them an imei of a S7 or s8 att branded phone. Then they will allow you to get volte, wifi calling, video calling and visual voicemail. That is after you flashed their csc.
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] blkghost22:
I tried that and none of them works.the phone call doesnt go out and just hangs up immediately.

Has anyone been able to get any USSD codes to work on US unlocked firmware?
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] dtomlin:
If you flash their userdata that will work anyway. Im saying that a non-at&t phone won't have the software to support it. But by flashing their userdata with unlocked firmware, you won't receive updates OTA.

---------- Post added at 12:58 PM ---------- Previous post was at 12:54 PM ----------

I flashed the AT&T userdata in the ums slot in odin, and everything worked fine for me. I just wanted to receive the update OTA so i reflashed to full U1 firmware. I guess when your files are "frankenphoned" then you wont get OTA updates.

[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] nugzo:
is the white pages integration in 955U1 (caller ID for unknown numbers and Spam detection) the same as the canadian 955W? some of the early posts in this thread are confusing concerning this feature. Also for the ATT Users what is your favorite configuration? 955U1, 955W, 955U or a combination of these. I really want the caller ID and Spam detection. Would also like wi-fi calling and VoltLE if possible. Mainly caller ID and WIFI calling.. dont care about video calling. Will any combination of the available firmware get me what i want? Dont mind manually updating as i know OTA will be broken. TIA
[AT&T Samsung Galaxy S8+ Guides, News, & Discussion] dtomlin:
On 955U caller ID doesn't work. On 955U1 Wi-Fi calling doesn't work. I personally like the 955U1 but that's because I never used wifi calling or video calling. Only thing I miss is VOLTE, but I can live with out it as in still get good signals and clear calls.
