Yeah i used my friend's cricket SIM card and those settings did pop up for me as well. It seems like you're gonna have to fiddle around in the settings until you find the sweet spot then. Unless you can find a app on the play store that can help you toggle VoLTE.
[Samsung Galaxy S8 Guides, News, & Discussion] t12icky0:
So what I'm trying to figure out. I flashed the unlocked firmware on my s8 but I have cricket wireless. Am I able to flash just the csc from at&t to get volte working again?
[Samsung Galaxy S8 Guides, News, & Discussion] HighOnLinux:
I wouldn't recommend AT&T's CSC, I would rather go for T-Mobiles since i hear more good things about it rather than AT&Ts
[Samsung Galaxy S8 Guides, News, & Discussion] t12icky0:
I saw this, I'm on aio so figured I would give this one a try. It's the AIO unlocked firmware.

[Samsung Galaxy S8 Guides, News, & Discussion] HighOnLinux:
Give it a shot, bud. Just keep it updated onto what's the result
[Samsung Galaxy S8 Guides, News, & Discussion] bricky23:
This is what I have. Shows that it's active, but still don't get volte. But I think it has something to do with my account, because I don't get volte with an iPhone either
[Samsung Galaxy S8 Guides, News, & Discussion] t12icky0:
What firmware did you use? I've tried every firmware and still don't see the enhanced services.
[Samsung Galaxy S8 Guides, News, & Discussion] bricky23:
I did it a couple different ways. Right now I have my csc set to ATT. I flashed U1 firmware, then flashed att user data. But I got the same results when csc was set to AIO.
[Samsung Galaxy S8 Guides, News, & Discussion] t12icky0:
So when flagging the ums(user data) will you need to wipe? Or did you just flash it in odin and restart? That's what I'm confused about.
[Samsung Galaxy S8 Guides, News, & Discussion] bricky23:
Yes flash in odin, in ums. It will wipe your phone when it is flashed.
[Samsung Galaxy S8 Guides, News, & Discussion] t12icky0:
Ok thanks for letting me know. Much appreciated.
[Samsung Galaxy S8 Guides, News, & Discussion] Sxmsung:
Well I'm late to the party but it seems jesec has TWRP for our SD variants already, we just need our BL unlocked to use it :(
[Samsung Galaxy S8 Guides, News, & Discussion] t12icky0:
Thanks man, finally got all the enhanced settings back up and running.
[Samsung Galaxy S8 Guides, News, & Discussion] bricky23:
So you actually get volte now? When you make a phone call, it stays on LTE? Not switching to 4g.
[Samsung Galaxy S8 Guides, News, & Discussion] t12icky0:
I used the unlocked aio firmware instead of the att firmware. Then used the ums file to get volte and all cricket features working again and also get the unlocked hotspot(the main reason I went to the unlocked firmware).
[Samsung Galaxy S8 Guides, News, & Discussion] HighOnLinux:
Could you activate it through a code through the dialer? I never had cricket before, just borrowed a friend's sim that was on cricket and i seen the same settings he had as well.
[Samsung Galaxy S8 Guides, News, & Discussion] bricky23:
Could you elaborate a little? Your csc is AIO? You flashed the AIO unlocked firmware? Then flashed the user data from ATT firmware? Correct?

---------- Post added at 05:42 PM ---------- Previous post was at 05:39 PM ----------

It is enabled in setting for me, but still not working. I think maybe I will have to switch to a cricket phone that gets volte, then switch back to this one? I don't know.
[Samsung Galaxy S8 Guides, News, & Discussion] t12icky0:
Exact process was exactly as you said.

1. Flashed the Aio unlocked firmware

2. Flashed the ums from att after flashing the aio unlocked firmware.

Then all features worked. It even has the cricket boot logo again. I would assume flashing the ums from att at the same time as the unlocked firmware would work also but that's the way I did it.

It's working for me, I checked the setting and then made a call to confirm. My phone was originally a cricket phone I bought from cricket so maybe that might help?
[Samsung Galaxy S8 Guides, News, & Discussion] HighOnLinux:
Well switching towards another cricket phone isn't neccessary you can try another redirection. How about trying to flash the CSC with T-Mobile and just keep everything intact? Does that sound good to you?
[Samsung Galaxy S8 Guides, News, & Discussion] bricky23:
In order to change csc, it will wipe everything and change firmware. But I will try it.
[Samsung Galaxy S8 Guides, News, & Discussion] bricky23:
Did you flash home, or non home csc file, in AIO unlocked firmware?
[Samsung Galaxy S8 Guides, News, & Discussion] t12icky0:
Non home csc.
[Samsung Galaxy S8 Guides, News, & Discussion] HighOnLinux:
Well good luck to you and hope everything goes well at the end
[Samsung Galaxy S8 Guides, News, & Discussion] t12icky0:
Did you end up getting volte working?
[Samsung Galaxy S8 Guides, News, & Discussion] bricky23:
Not yet. Haven't had time to do anything yet. Maybe I will have time tonight or tomorrow.
[Samsung Galaxy S8 Guides, News, & Discussion] bricky23:
Reflashed but still no volte. Shows that it's enabled, but doesn't work. I think maybe I will have to put my sim into an actual cricket phone, to get it working. Then switch back to this. I had it working before with an iPhone 7 plus, an axon 7, and with this phone, when I 1st flashed it to cricket. Now it doesn't even work with an iPhone.
[Samsung Galaxy S8 Guides, News, & Discussion] t12icky0:
Kinda sucks, hope you get it working. By chance do you get the cricket logo when booting up?
[Samsung Galaxy S8 Guides, News, & Discussion] t12icky0:
Plus here is my csc and files.
[Samsung Galaxy S8 Guides, News, & Discussion] bricky23:
Yes
[Samsung Galaxy S8 Guides, News, & Discussion] t12icky0:
Do you have the same setup I do as in my photo above?
[Samsung Galaxy S8 Guides, News, & Discussion] t12icky0:
Maybe I just lucky and got the right configuration or something. Hope it works out for you.

Flashed the firmware on my galaxy t mobile G950U, ......worked fine, all bloatware gone also received OTA updates.

Thanks to all.:o
[Samsung Galaxy S8 Guides, News, & Discussion] jpcdeux:
I have an att S8 running the G950U1 XAA fw. When I flash the att UMS I get the features but can't make phone calls. When I try to call any # it ends the call instantly.
[Samsung Galaxy S8 Guides, News, & Discussion] HighOnLinux:
That happened to me twice. Just keep on calling the same person or your voicemail twice in a row. It should go away since i did that and it permanently went away. If it doesn't go away, i honestly don't have a different solution to help.
[Samsung Galaxy S8 Guides, News, & Discussion] bricky23:
Finally I have volte working. Not sure why. I have been using an iphone se for the last couple days, so that I could get it unlocked by cricket. Had to switch to the unlimited plan, long enough to get it unlocked. I then did a factory reset on the s8, flashed regular u software, put my sim card in. And now have volte. Not sure which part made it work. However, the new bixby won't work. Says that I need to update my software, but when I check, there is no update. I have downloaded the newest update from updato. But afraid to install. Maybe loose volte. But I want bixby voice more, so here goes.
[Samsung Galaxy S8 Guides, News, & Discussion] t12icky0:
Bixby sucked..ha. Maybe with a few more updates but the talk to text is just horrid. Congrats tho on getting volte finally.
[Samsung Galaxy S8 Guides, News, & Discussion] bricky23:
Thanks. Flashed the newest tmb update, and still have volte, whooh. Seems like it runs much better also. Thank goodness, done flashing..........for now.

AT&T S8+

I've tried this so many different ways and with different firmware files and odin versions, but each time it completes successfully and I still have the AT&T startup animation and setup screens. It will always say att/att/att as well. I'm stuck. Any ideas??
[Samsung Galaxy S8 Guides, News, & Discussion] HighOnLinux:
Did you used the modified princecomey's version of odin?
[Samsung Galaxy S8 Guides, News, & Discussion] billa:
Most likely your bands are messed up, somehow inadvertently selected LTE only, therefore data works but no calls.

First, remove the AT&T sim (because it's RAT locked), then dial *#2263#, click on reset bands, apply, and finally enable all bands, enable.

Try calling again, and let us know if it worked.
[Samsung Galaxy S8 Guides, News, & Discussion] jpcdeux:
Flash the u950w xac fw with non-home CSC. Setup like normal. Go into lock screen settings and setup secure startup. Then flash the g950u1 XAA with home CSC. You'll end up with straight no carrier unlocked fw if that's what you're going for.*

(That's what I did for S8. Use 955 versions as you're on an S8+)

You can use google's VR service. Unless you really prefer using gear VR. I don't really have an answer for the VR problem since i dont use VR myself so good luck finding a solution to that.

I would have to buy the Google VR set up because with the samsung one Google VR doen't work. Thanks mate, let's see.
[Samsung Galaxy S8 Guides, News, & Discussion] HighOnLinux:
This might sound extremely noob-ish but, do you still have the user manual for the gear VR? Meaning a little QR Code for the headset alone where you can scan with your camera and register it to your phone? That method may work.
[Samsung Galaxy S8 Guides, News, & Discussion] jongcruz:
I might have it, will try that.

update: no bar code to scan in the box.
[Samsung Galaxy S8 Guides, News, & Discussion] HighOnLinux:
That's unfortunate. I'll try to find a solution for your problem and update my reply if possible.

"advanced calling" not available in setup on G950U1

I bought an unlocked 950U1 from Best Buy on sale, I thought it would be better than having verizon bloatware. in the phones settings, I don't have "advanced calling" option, which is required for data during calls. this resulst in WAZE not having any connection if I'm in a call, which is most of the time I'm using WAZE. Also, while on phone with a customer, and they send me a picture by email or text, I have to disconnect the call to get the message. as soon as you initiate a call, the data bars go blank, they don't come back until you end the call.

I have VoLTE calling, but that changes nothing. at the verizon store, we swapped some sim cards with verizon phones that had the "advanced calling" option available, in my phone, it removed VoLTE calling option, and changed a couple others, but no "advanced calling" option, or any option which enables data during calls.

the phone is currently on Page Plus, but i'd like to switch to verizon pre pay. that also didn't work. after i paid the non refundable $50, the phone would not activate on Verizon.

Oh, just as a side note, a verizon galaxy S5 worked for several years on page plus with data during calls, but the charge port went bad and was "not repairable" according to the shops I took it to.

is this the right place to possible get help?
[Samsung Galaxy S8 Guides, News, & Discussion] Thor2j:
U need to flash Verizon firmware
[Samsung Galaxy S8 Guides, News, & Discussion] HighOnLinux:
This thread is for those whom wish to switch from a carrier-branded firmware (U) to the unlocked firmware (U1), which is what you have. The instructions prompted from the OP isn't for you, but i'm here to help.

Since you're having issues with verizon's data, i have one question to ask. When the network switched during a call, would it go from LTE+ to H(+)? Other than that, i'll see what i can do. Let's do the basics. Reset your APN back to default. If that doesn't work, try going down to the network operators, and choose "Select Automatically." If the basics don't work for you, There's an app on the Play Store known as "4G Only Network Mode" download that, open the app up, select the "open secret settings" and change the preferred network type to "LTE only" your data should turn off for a second then restore itself to LTE again. After you're done with that, give someone a test call. If that doesn't work, we're going to have to do some more advanced things here. If neither options worked for you, go to your system settings>General Management>Reset>Reset network settings that's one of the last 2 options you could have for yourself. If none of the other options worked for you, this is the last resort you're going to come to. You're gonna have to flash the CSC file from the unlocked firmware file you can download from the OP. After that's done and over with, extract the unlocked firmware file and multiple files should pop up. I'd recommend to put that file onto your desktop for easier accessibility. After you've done that, open the modified Odin. You're going to place the CSC file in the "CSC" section in odin. Plug in your phone, boot it into download mode and press the start button on odin after the phone has booted into download mode properly. Be warned, if you do the last option, consider having a backup of your items on a PC/Laptop, since it will (possibly) reset your phone to factory settings. If none worked, I'm sorry but you're gonna have to talk to samsung support about that issue.

---------- Post added at 06:13 PM ---------- Previous post was at 06:11 PM ----------

That's a possible solution, but he'd rather stay unbloated.
[Samsung Galaxy S8 Guides, News, & Discussion] MrLeon:
So i have a T-Mobile S8+ that i would like to use on Verizon. What is the easiest way for me to do this? Do i have to go from TMOB -> XAA -> VZW or can i just use it on the XAA?
[Samsung Galaxy S8 Guides, News, & Discussion] Thor2j:
Is it SIM unlocked
[Samsung Galaxy S8 Guides, News, & Discussion] MrLeon:
Yes, it is sim unlocked.
[Samsung Galaxy S8 Guides, News, & Discussion] HighOnLinux:
You can use odin and flash the unlocked CSC file from unlocked firmware (U1).
[Samsung Galaxy S8 Guides, News, & Discussion] MrLeon:
Thanks. That's it? I don't have to do all the steps listed out in these other posts? Does that have to be done with the regular or modified Odin?
[Samsung Galaxy S8 Guides, News, & Discussion] HighOnLinux:
Modified odin
[Samsung Galaxy S8 Guides, News, & Discussion] MrLeon:
HOME or Non Home?
[Samsung Galaxy S8 Guides, News, & Discussion] HighOnLinux:
From what i did, i'd say home. Just have the modified odin and you'll be set
[Samsung Galaxy S8 Guides, News, & Discussion] MrLeon:
Alright, i swear this is the last question before i try it.

Just to be clear, I use the modified Odin to only flash the Home_CSC. I don't have to worry about the AP, BL or CP?
[Samsung Galaxy S8 Guides, News, & Discussion] HighOnLinux:
Well if you want to still be unbranded (which u brought up) just flash the home CSC
[Samsung Galaxy S8 Guides, News, & Discussion] billa:
But wait, he guy said that has the S8 (950U1) which is already on the unlocked/unbranded firmware "U1", and you've instructed him to flash the CSC part only of the unbranded "U1".

I don't think that would work, unless you've meant the CSC part only of the branded "U" firmware in order to activate the advanced features backed into that.

Now, if he had the "U" already on the phone then perhaps the CSC part only of the "U1" might work, or vice versa.

Correct me if I'm wrong. ;)
[Samsung Galaxy S8 Guides, News, & Discussion] MrLeon:
Thanks. That was easy.
[Samsung Galaxy S8 Guides, News, & Discussion] HighOnLinux:
From what i know, it works vice versa
[Samsung Galaxy S8 Guides, News, & Discussion] billa:
So, just to clarify...

If he has the unbranded "U1" on the phone then flash the branded "U"s CSC only?

Does the UserData part needs to be flashed along with the branded "U"s CSC?

OR

If he has the branded "U" on the phone then flash the unbranded "U1"s CSC only?

Which combo will give an un-bloated yet full advanced call feature carrier experience?

I'm just asking to learn something :)
[Samsung Galaxy S8 Guides, News, & Discussion] HighOnLinux:
I'll be copy-pasting the exact thing you just said

"If he has the unbranded "U1" on the phone then flash the branded "U"s CSC only"

That's the right thing to do if you want specific features like wifi-calling and VoLTE. but for me, i flashed to U1 firmware from t-mobile's and flashed the home-csc file as well and it works great with all the features included. but it all depends on the carrier as well. Since something like AT&T and verizon blocking a certain feature, you can always flash a different CSC file to acquire those features anytime, despite you being on the U or U1 firmware. But for the unbloated experience, flash U1 firmware and like i said earlier, if you're looking for a specific feature not present due to the carrier limiting it, flash another carrier's CSC file.
[Samsung Galaxy S8 Guides, News, & Discussion] billa:
Got ya, that's what I was thinking too just wanted to hear it from others as well, but besides the CSC part what about UserData part, is that necessary for just ATT VoLTE, or not really? Don't care for their bloat either....
[Samsung Galaxy S8 Guides, News, & Discussion] HighOnLinux:
If you would want enhanced features, i'd say go ahead and flash it. If it's not fancy for you and you don't care, you can still flash it, but is optional to use the features. But it will come in handy if you ever need them.
[Samsung Galaxy S8 Guides, News, & Discussion] billa:
Do you know what specific features are in the UserData if VoLTE is already in the CSC (or is it)?

It's good to know... :)
[Samsung Galaxy S8 Guides, News, & Discussion] HighOnLinux:
Well userdata from what i know doesnt contain any secret features, but from what i mean by enhanced features, i mean how if you flash the userdata and you ever switched to a carrier that limited a certain feature, you'll still have it no matter what you do.

not sure it makes a difference but I'm not getting sprint logo at startup. I'm getting Samsung, In download mode it shows XAA and the actual CSC is showing XAS and not SPR.

any insight would be greatly appreciated.
