Hint, hint, hint.....

Not for me - I am on TMB, but for others who are suffering enough being AT&T customers.

PS - some beer money on the way TEKHD -thanks for this mod - its going to let my S9+ become my daily.
[Samsung Galaxy S9 & S9+ Cross Device Development] tiskewlio:
So just so I am understanding you correctly, coming from stock, I have to first flash TWRP, then flash a custom rom, and lastly flash this detonator? So then there will not be any jail?
[Samsung Galaxy S9 & S9+ Cross Device Development] TEKHD:
Thank You!

gaww, got donation. Wanted to say Thank You. Yesterday, I added a "Donators" section. Sorry for the ultra late reply. (I am currently working on the page) Again, thank you! By the way, TMO Detonator v2.3 coming soon and also a AT&T Detonator v1 is coming soon.

Exactly my friend.... Detonator is the last thing you flash.

AT&T S9/S9+ users that want to test the AT&T Detonator... please go to the DETONATOR section on my webpage and click the support sub-section.
[Samsung Galaxy S9 & S9+ Cross Device Development] gaww:
Looks like it was within the realm of possiblity!
[Samsung Galaxy S9 & S9+ Cross Device Development] Alarand:
v2.3 flashed fine for me and it appears all the features are enabled. Currently on S9+ dual sim using soldier9312's rom. I did notice that the call settings > more settings menu gives me a failed to read data error. I can still use the menu after dismissing the error so I don't know if it matters.

I checked my mps_code.dat and it's set to TMB. omncw_code.dat file is still set to BRI though. I actually have an omncw_code2.dat file that is also set to BRI. I'm assuming this is because of dual sim? Should I bother changing them and reflashing or is that unnecessary? Service provider code in settings is TMB/TMB/BRI

Thanks a ton for making this.
[Samsung Galaxy S9 & S9+ Cross Device Development] gaww:
2.3 - don't see it on the OP ?

I am on same rom with 2.2 - any need or benefit in upgrading?

PS - get same error notice in call settings also ignore it.
[Samsung Galaxy S9 & S9+ Cross Device Development] Sunnyschlecht:
Appreciate all the work you put in this mod. I had some troubles actually with my phone being network locked until I restored everything to stock. Now I'm just playing with the ims settings without having flahsed your zip. I did get the volte settings to stay on but for some reason the rcs settings don't seem to stick and keep turning off. How did you manage to make them stay on? I'm just trying to get volte and rcs (if possible) to work without the annoying wifi calling and all the tmb bullsh*t. Video calling and everything else works great. You really are amazing sir!

[MENTION=4107827]TEKHD[/MENTION]

You are the man!!!

Just wanted to say thank you! I currently have the SD version of S9+. Want root but need wifi calling due to service issues in my house. So I am going to sell it and get the Exynos version.

Donation will be coming soon.

Thanks again.
[Samsung Galaxy S9 & S9+ Cross Device Development] gaww:
If you have TMo with lousy reception, you should be able to get them to "loan" you a cellspot, which piggy backs on your WiFI., so you do not need WiFi calling at home..

I use WiFi calling elsewhere, so was really glad to see this mod so soon.
[Samsung Galaxy S9 & S9+ Cross Device Development] bighit101:
[MENTION=1871826]gaw[/MENTION]

Hi, yes I have that aswell but even though the reception bars obv my phone show full reception with it (without it I get maybe 1-2), the service is still not good. My voice calls are not clear at the other end.

I have always had root on my phones, but Samsung and snapdragon haven't been the best when it comes to root from my experience anyways. So this mod would kill 2 birds at once.
[Samsung Galaxy S9 & S9+ Cross Device Development] gaww:
What is your Baseband Version ?
[Samsung Galaxy S9 & S9+ Cross Device Development] metal450:
So I just installed this on top of Alexandr's ROM. The installation seems to have worked: Phone Info shows TMB for both Original CSC Code & Active CSC Code, and TMB is also shown under About Phone→Software information→Service provider SW ver. I was able to enable & use Wi-Fi- Calling.

However, call recording in the stock dialer is not working. The "Record" button is there, but pressing it does nothing. Note that I did actually test this on Alexandr's ROM prior to installing the Detonator, and it worked - so it appears to have been explicitly broken by installing this.

Any idea?

Edit: My device is SM-G960F (dual-sim, with one sim inserted)

Edit2: Solved. It's because call recording doesn't work on WiFi Calling. Turn off WiFi calling, and the Record button will become functional once again :)
[Samsung Galaxy S9 & S9+ Cross Device Development] gaww:
I am on 965F DS and on Soldier ROM (1.9). Selected this setting here (2.3) and working fine - just tested it.
[Samsung Galaxy S9 & S9+ Cross Device Development] flamingcat:
Just wanted to ask if anyone that's installed it can confirm or deny that it will install T-Mobile's "bloatware" - the "Device Security" and the ugly as h*** boot logo/sound.
[Samsung Galaxy S9 & S9+ Cross Device Development] gaww:
I have not noticed any bloat and I have no boot sound.
[Samsung Galaxy S9 & S9+ Cross Device Development] flamingcat:
Could you check Device Maintenance and tell me if the "Security" scanner is active in it?
[Samsung Galaxy S9 & S9+ Cross Device Development] gaww:
The only security thing I see in Device Maintenance is Device security, which is deactivated.
[Samsung Galaxy S9 & S9+ Cross Device Development] metal450:
From researching in another thread, I figured out the issue: it apparently just doesn't work with WiFi calling. Since Detonator fixed WiFi calling, call recording appeared to die - if I turn off WiFi calling, I can get call recording to work once again :)
[Samsung Galaxy S9 & S9+ Cross Device Development] metal450:
I'm also having difficulty sending MMS, though after some experimentation, I realized that it's actually only *large* images that fail. If I go to messages->Settings->Chat settings->Image size=Small (10%), it works - but anything larger than that and I it fails, showing "Network error occurred."

I'm on SM-G960F (dual sim).
[Samsung Galaxy S9 & S9+ Cross Device Development] Android_858:
lm also seeing the same issue sending MMS larger than the small size within settings. I'm on T-Mobile in the US with a G965FD
[Samsung Galaxy S9 & S9+ Cross Device Development] gaww:
It works on mine on WiFi calling, but only if I select it before the call is answered. Then I can turn it off and on - odd.
[Samsung Galaxy S9 & S9+ Cross Device Development] metal450:
Not me. Even if I try to enable it while the call is ringing, the button is non-responsive.
[Samsung Galaxy S9 & S9+ Cross Device Development] StormTrooper0307:
I'm using LineageOS (Oreo 8.1) on my S9+ N965FD. Bought the device in Spain and currently using it fine on T-Mobile (sans Wifi calling) in the US. Can I use this partition with LineageOS or does this only work with stock/modified Samsung ROMs?

I have noticed a small improvement on TMo where I live.
[Samsung Galaxy S9 & S9+ Cross Device Development] shouren04:
[MENTION=4107827]TEKHD[/MENTION]

FYI, I noticed none of the detonator zips install with correct permissions. Looks like the zip was made with Windows & there is nothing in the script that sets permissions for all the files & folders that get installed. Xml files still load but apks may have issues. This could be why some people are having issues?

With your S8 TMO zip, the permissions are saved in the zip so everything gets installed with the correct permissions.

Hi!

First, thank you for your hard work. Everything working fine, I have only two problems.

1 I'm using handcent sms, and delivery report always show me pending, the stock sms app working fine.

2 When I try to open in the phone settings, more setting, I got a message " something went wrong, Check your sim card or network connection "

Any solution on those problem?
[Samsung Galaxy S9 & S9+ Cross Device Development] drbawb:
This seems to be working well on my SM-960F/DS but I'm having trouble getting visual voicemail working:

1) Phone > Settings > More Settings returns an error "Failed to read data"

2) Visual Voicemail doesn't work - clicking the icon just dials my voicemail number. The voicemail related settings have also disappeared from my Phone > Settings menu.

3) If I manually launch the TmoVVM apk included in the T-Mobile CSC, it launches but has an empty inbox. I can get to the voicemail settings from here, however all the settings menus are empty, asking me to "select a line." (Maybe an unfinished menu for the dual-SIM variant?)

Any thoughts? It'd be great to have VVM in the dialer.
[Samsung Galaxy S9 & S9+ Cross Device Development] gaww:
Yeah VVM doesn't seem to work.

I'm getting this error now every time . I asked tmobile and they gave me 2 different numbers and is not working. Also I did factory reset and nothing works. Any help please
[Samsung Galaxy S9 & S9+ Cross Device Development] sabresfan:
I had the same problem happen to me. I have a 965f duel sim. The only fix I found was to flash the devbase rom. It seems some phones get picky for whatever reason. Hopefully you still have twrp installed if not you gotta wait 7 days until you can flash it again. Good luck
[Samsung Galaxy S9 & S9+ Cross Device Development] Bestplayer55:
Did you remember which version did u flashed and any option in particular?
[Samsung Galaxy S9 & S9+ Cross Device Development] sabresfan:
Latest version. There are no options to choose.
[Samsung Galaxy S9 & S9+ Cross Device Development] Amd4life:
Your SiM lost the data info...it happens sometimes, hence the need for a FULL working backup, that contains your EFS, and modem info.

Easy fix, well works for me;

Reboot to recovery

Format, click yes

Reboot recovery

Wipe everything , EXCEPT microsd card.

Install renovate 1.2, choose CSC USA, CODE 310

That should recovery your data connection on first reboot.
[Samsung Galaxy S9 & S9+ Cross Device Development] vponomarev:
Does it actually save the recording? I'm getting "Failed to save recording" at the and of the call when I press record button just before the call is answered, so that it appears that the call is being recorded the whole time. Automatic recording does not kick in.

With Wi-Fi calling turned off, everything works.
[Samsung Galaxy S9 & S9+ Cross Device Development] tiskewlio:
Everythinf works great after flashing this but I have a Data Usage text in my notification area under the QS icons. Canr find a way to get rid of it any help is appreciated
[Samsung Galaxy S9 & S9+ Cross Device Development] Alarand:
I just did a fresh install of soldier9312's bre5 stock rom from his ard4 rom and I seem to have run into the sim lock issue. I flashed the detonator after the rom and FW update without rebooting inbetween and got the lock message on boot. I tried reverting the region codes back to BRI then reflashing the rom without the detonator but the lock's still there. Going to try a full wipe with a different rom

Edit: Fresh flash with devbase and no more sim lock

Thanks.

[Samsung Galaxy S9 & S9+ Cross Device Development] gaww:
He hasn't been heard from here for a while, so I will take a shot - I believe it will work on stock as well as a few other ROMs I have used it on.

Hey [MENTION=4107827]TEKHD[/MENTION], great work on getting this on our unlocked devices! Question is it possible for you to port this for the Canadian XAC CSC particularly the RWC for Rogers carrier? I have the g960f as wanted it unlocked and to flash AOSP but so far found no CSC that voLTE and WiFi calling works on. Since the g960w is the Canadian equivalent of the s9, the CSC files are available so hope it is a similar process you did for TMO. Thanks again!

Root device and do this:

Here

Done... Problem solved. Now you can flash any stock firmware and everything will be back to normal. The problem is that you have TMB on that file with no T-Mobile CSC installed. Basically, you went to stock or another ROM that doesn't have TMB CSC, but since your phone is set for TMB (and there is no TMB CSC...) then you get that screen.

and... you did not follow instructions and have no nandroid...

4G LTE ?

So after installing this i shouldn't have problems connecting to 4g LTE ?

Does it help with the Tmobile signal ?

I have the international Duas wit Serve provider XME XME XME 126Gb but my signal suck i get 1 to 2 bars in the house.

My wife has the tmobile Vertion and she had full bars with 4G LTE .

Flashing this will resolve also the signal problem ? If not how can i convert it to a full Tmobile S9 plus Im new here and im totally done with HTC after 9 years. lol

Hi, I have a few questions to those who have successfully performed this update. After installing this, do you get better reception with Tmo? I'm currently using a GS9+ from Singarpore and my reception is always around 1-2 bars and only on 4G. I don't think I've ever seen LTE on the status bar. Also, does this break KNOX? Thanks.
[Samsung Galaxy S9 & S9+ Cross Device Development] gaww:
If you install recovery (TWRP) - that breaks KNOX. I used with TMo in the US, which this was developed for. The CSC mods out there may handle yours - so search and find out.

Breaks MMS

Anyone having issues sending MMS with Samsung messaging?. Installed the latest 7.3 Soldier9312 ROM and all was well. Then flashed Detonator and get Network fails to send MMS attachments. WIFI calling works no issues which is why I really would like to get this figured ou, simce Tmob service where I live is poor, in my home. Also had same issue with the latest BRH1 Developer 5.9 ROM.

This failed every time I attempted to install. Not to take away from the work of this Dev, but I downloaded and installed Shortcut Manager and activated VoLTE there. I still dont have RCS related features, but at least for now I have VoLTE. VoWiFi may also be working, but with no indicator present in the status bar, its hard to tell.
[Samsung Galaxy S9 & S9+ Cross Device Development] gaww:
I am having problems with MMS and Samsung messaging and didn't know this might be responsible.

Work-around for me is to send MMS on Goggle messaging and then switch back to Samsung. It then appears there also.
[Samsung Galaxy S9 & S9+ Cross Device Development] Docmjldds:
Trying an app called Pulse from Playstore. Remarkably close to Samsung message app and no issues. But for sure Detonator is the issue. But love WiFi calling. Also, not that it is a concern, but with Detonator the OEM unlock actually shows up as ON in developer options.
[Samsung Galaxy S9 & S9+ Cross Device Development] gaww:
This is still the only option for US carriers - just wish someone would com up with a normal CSC for TMo and AT&T over here. This was a good piece of work, but it wasn't finished, and the OP just disappeared.

So sharing info by uses is the only help we get - and it is appreciated.
[Samsung Galaxy S9 & S9+ Cross Device Development] Docmjldds:
Yeah...would be nice for OP to chime in here. I was so thrilled I sent him a donation when I first used this. Never heard back but still is a valuable add on for us Tmobile users here with the Exynos S9. Even the thread should have been renamed to the current version T-Mobile EFS/CSC Detonator

Detonator v3 for Oreo (Samsung Galaxy Note 8 F/FD, Samsung Galaxy S8/S8+ F/FD & Samsung Galaxy S9/S9+ F/DS).

Absolutely knowing how to edit the EFS/IEMI files too so that you do NOT get PUK locked SIM message when installing any other ROM is critical too.

It always has been users here that take the time to state issues and get feedback from others is what makes XDA worth it's weight in gold :)
[Samsung Galaxy S9 & S9+ Cross Device Development] gaww:

EDIT: Seems I just now read a post from OP on his web site to NOT post direct links on XDA. I guess I'm guilty as charged but since I don't see any posts here from the developer as well as I did donate to OP, I am only trying to help out users here. If I get a message from OP I will delete the links

Found a fix that NOW allows stock messaging to send MMS with no issues. Install the Alexander CSC changer to TMB. From what I see, it edits the prodcode.dat file to also end in TMB. OP instructions were to rename the file using CSC as the first three letters in name of file. Anyways I renamed the file using TMB, flashed with TWRP. What's funny is the Tmobile jingle also played with the Tmobile splash screen on booting up. Have not tested this on any other Rom but the 5.9 Alexander Developer ROM.

PS....he just uploaded a new version of ROM. But here is link to the CSC changer for USA.
