I gotta say major thanks to you [MENTION=Kalm_Traveler;74122190]..

Using your zip and adding my RWC folder into it I now have full volte and wifi calling working

Where did you pull these files from the N950F? or the N950U tmobile firmware?

Using the ones I was supposed to be using, the phone kept turning off the services and my carrier could see my new device, once I swapped your ImsService and other related system apps, my carrier is unable to see that I have switched phones! they still see that I am on my Note7, and allow the enhanced calling features to work.. kinda funny I put the wrong files in so they cant see the new device but it was provisioned on last device so it still works... heh

Keep at it, you will get it.. im sure.. now I am taking a nandroid of volte all working on DRKetan's rom and RWC csc... before I break it all again to get LTE+ working!

Where or what are you using to confirm/enable MIMO and aggregation?

ON my note7 using *#0011# I can easily see multiple LTE bands connecting when the + is there up to 4 of them, then as they drop off and only one remains the + is also gone. I am about to revert to stock LUC (LG uPlus) which is my SMN950NKOR CSC to take a look in that screen for multiple LTE connections.. might as well check where you are mentioning before I reflash stock
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
I grabbed what the F had that the N did not, and the CSC files from the U for tmobile matching the files that other packs use for F variant S8's.

This service menu is accessed via a shortcut app, secret code explorer, number 27663368378
[Samsung Galaxy Note 8 Questions and Answers] gundal:
tyvm for that I will download it now and play around.

so the /system/app/imservice/* and epdg and all that came from the F? not the U (to triple verify.. the ONLY files that came from the U were in omc/ ?
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
off the top of my head, the /omc/ files, as well as tmowfcpref, wfcservice, some framework .jar files, vowifi, and atfwd came from the U. I will double check in a minute when I can take a break (work is actually busy today for some reason).
[Samsung Galaxy Note 8 Questions and Answers] gundal:
I typed service code explorer in google play but couldnt find a specific one that looked like I match, about 5-6 came up, can you tell me the author or package name?

I have downloaded a few of these and see some promissing stuff.. like LTE band selection, and GSM band selection (which had USA/EUROPE etc.. but failed to change).

but I still want to see the one you are referring to.. there is also of course the *#197328640# which is a debug menu on most samsungs
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
The one I have is called Shortcut Master
[Samsung Galaxy Note 8 Questions and Answers] gundal:
IMS settings in this shortcut master is pretty interesting as well

code *#77467#

it can see all the hidden IMS settings for my carrier! interesting and useful to see it for once

well I found the menu you are referring to.. but did not find the setting you are referring too..

I just did a speed test with my single LTE band...

got 103.88 MBPS Down and 14.83 UP

thats not too bad.. lol
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
the menu options: Etc -> Common -> ANT Test Setting

That is very good for a single band. Before my usb/antenna board took a dive I was able to get between 100 and 200 down depending on server and time of day. In it's current state I can barely maintain cell tower connectivity in most areas so the speed tests often fail, especially on the upload part.
[Samsung Galaxy Note 8 Questions and Answers] gundal:
yikes that is very depressing!! I would think it has to do with the bands it prioritizes.. do you have an older tmobile branded samsung device you can pull the settings up on and compare..

thanks taking a look now at ANT stuff then will reflash stock

so if you dig deeper into PCIE info, you can see it says 4x4 MIMO: NOT SUPPORTED.

we will see what stock has shortly
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
Yes I still have my T-Mobile Note 5 with an active SIM card. It's not a software issue, as I found that applying pressure on one of the antenna connectors on the lower PCB made the signal strength shoot back up to normal. Both devices seem to favor the same bands in the same area, and if I press on that connector just properly it's signal strength is the same or greater than the Note 5 in the same spot. From looking around here it sounds like a few of us with Korean models have had issues with that board (the mic, speaker, USB port, and 2 of the antenna are on/in it).
[Samsung Galaxy Note 8 Questions and Answers] gundal:
omg thats soo terrible, sorry to hear that... my note5 exynos version had a faulty Bluetooth, luckily I noticed it within 15 days and was able to return it to the ebay vendor for a replacement

I just confirmed the N950F has a similar if not the same modem as the N950N and the modem.bin looks to be compatibile with either... one other intersting point is the stock N950F firmware insiide the CP_N950FXXU1AQHB_CP7250176_CL12007350_QB14652984_REV00_user_low_ship.tar.md5 tar file actually had a modem.bin and a modem_debug.bin ... I cant view the modem_debug.bin file with a text editor

I can confirm carrier aggregation is not working.. I only hit the same download speed with my note7 but upload hit 50 mpbs, more importantly in `LTE Discovery` I can see that while im connected to one PCI (physical cell identifier) tower, I can also see about 2-8 other towers, on my note 8 in LTE discovery I only can make out the one tower I am connected to. gonna flash N950N stock rom now and compare! will report back shortly
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
Sounds very interesting, thank you and I'm curious what you end up seeing!

As far as I can tell, everything in the 950F is exactly the same as the 950N hardware-wise so there should be zero issues using either modem (assuming one has better band support for your carrier or something). They both actually have 2 SIM card slots but without a 2nd IMEI for the 2nd slot I don't know of an ethical way to make use of it on a device not sold as dual SIM from the factory. I can say that on the N, if you switch your libsec-ril file to the F version, upon reboot you'll see a message indicating that the phone is switching to dual SIM mode.
[Samsung Galaxy Note 8 Questions and Answers] gundal:
Yes I have seen that popup asking me to reboot for a data wipe as it has switched to dual sim, after I flashed Dr.Ketans rom.. hmm are we sure it actually has a second slot? unless you plan on taking that aggressive confidence and cracking your device open to fix the antenna.. probably will never get to even reach it.. unless just a dual sim tray is needed and the gap still all lines up (I have one from my n9500..)

OK so I just reflashed my stock AP and CP via odin.. and I can confirm I am seeing both 4g and 4G+ during setup.. interestingly I am not showing my LUC csc so a bunch of stuff isn't working.. like any dialer codes..but 4g+ does... and a speed test hit 235 down and 35 up...

ok got some work to do now.. need to get aggregation and volte/wifi calling going together..
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
I pulled the back glass off last week to figure out why my LTE strength died - that's how I know it is something with the bottom PCB. You can very clearly see the 2nd slot below the first one (as well as the extra pins for reading the microSD card). You can buy the SIM trays but I believe you'd still need a 2nd IMEI for the other slot to be of use, unless somehow you can use the same one with both on 2 different carriers at the same time? I'm not really a good one to ask about the dual SIM stuff since I have never been in a situation where I would want to do that, honestly. See my thread about the signal issue: https://xdaforums.com/galaxy-note-8/help/n950n-owners-suddenly-terrible-cell-t3684902

Glad you can confirm the LTE+ stuff on factory CSC too, so I am not crazy. I bet you are not seeing the LUC CSC because your EFS partition still has the edited mps_code.dat and omcnw.dat files. As far as I know Odin doesn't touch the EFS partition.
[Samsung Galaxy Note 8 Questions and Answers] gundal:
odin doesnt touch it, but I also manually reset it back to LUC in terminal(echo "LUC" > /efs/imei/mps_code.dat), still shows //LUC (two nulls and LUC) in Software version. I also believe that a factory data wipe does something in /efs

So I just restored my /efs from the backup I had of my full volte working on RWC, and of course on stock system the RWC csc is missing... but that broke 4g+.. and then factory wipe brought 4g+ back.. just now..

more testing needed.. brb..

---------- Post added at 03:30 AM ---------- Previous post was at 03:15 AM ----------

Ok so heres my reproduction steps to definitively say that ^

1.Factory odin AP and CP (boot/recovery/system modem) = 4G no +

2. Factory wipe = 4G+

3. Restore RWC /efs = 4G no +

4.Factory wipe = 4G+

5. take a twrp nandroid backup of /efs

6. restore my userdata and my efs = 4G no +

7. restore my factory wiped /efs I took in step 5 = 4G+

now.. I am going to reinstall rogers RWC csc and get volte calling and then factory wipe? or restore that wiped /efs.. with mps_code.dat changed to rwc.. we'll see
[Samsung Galaxy Note 8 Questions and Answers] Kamikaze_Ice:
Since we're on the subject of the EFS partition, here is some strange behavior I've got for informational purposes.

I've used the PIT file to rebuild partitions, and also tried the "Phone EFS Clear" option and when flashing original firmware (Korean) and going to stock recovery I see Multi-CSC enabled and switching to AT&T.

There also seems to be issues loading "CACHE:/recovery/sec_omc.zip" claiming it does not exist after a fresh wipe. Although I can mount /cache and /cache/recovery/sec_omc.zip is right there.

I manually flashed it with TWRP, which finally changed my csc back. No clue why it fails when it exists and is mountable.

If I don't flash TWRP, the blue android update screen loads up to 32% then erases itself and reboots and returns to the update screen only to show "no command" and proceeds to boot into the system with no problems (never see the android update screen until data wipe). I'm guessing it's looking for the same sec_omc.zip and fails for the same reason and it does a /data /cache wipe when "erasing", but it tries to load the update script yet fails because of no file (showing "no command").

After a full clean wipe the stock recovery says it's switching to AT&T yet OS shows SKC (and files are appropriate as per firmware's CSC).

I don't think any of that will be helpful, but just in case lol.
[Samsung Galaxy Note 8 Questions and Answers] gundal:
for your own sanity, I can confirm I have seen the 32% exactly everytime... before it quits with error or no command or whatever lol.. I have found, if you have twrp, it can run those stock recovery scripts and it handles them just fine, I always reflash twrp before rebooting

---------- Post added at 04:09 AM ---------- Previous post was at 03:43 AM ----------

OOOOOO YEAA!!

that was easier then I thought it would be!!

restored my /system from a stock backup that had RWC CSC..

boom volte, wifi calling, RWC/RWC/LUC csc, and LTE+ icon displaying

:D today is a gooood day.. I am actually assuming a factory wipe will reconfig whatever was needed for carrier aggregation to work, as it seems thats the only thing that has changed for me.

---------- Post added at 04:20 AM ---------- Previous post was at 04:09 AM ----------

spoke to soon!! wifi calling is no longer working! it just sits on forever and eventually turn itself off, volte icon never goes away.... this is the issue you guys are having right??

---------- Post added at 04:56 AM ---------- Previous post was at 04:20 AM ----------

Alright! I am now sitting here with everything working.

I highly recommend you either, look into the DrKetan rom for our device and see what other files are missing between a diff of that device and our N. As soon as I restored my system from DRK backup, everything is good. 210.64 MBPS down 32 UP

If you are just gonna try out the DRK rom first to see if wifi calling will work on your TMO device, make sure you download the zip, open it up, add your CSC to the omc folder and change the sales_code.dat to TMB and add TMB to the sales_code_list.dat and the SW_Configuration.xml and then flash that and it should confirm if that rom has the bits necessary to get your wifi calling going. give it a shot.. thanks for letting me rattle on in your thread and work out my issue, I didnt mean to take it over lol.. but I hope I helped a bit.. and I hope the DRKetan rom has some missing files you need
[Samsung Galaxy Note 8 Questions and Answers] gundal:
I just read your teardown post.. man are you sure.. you were getting better then -90 before?

I get -94 to -100 with my note 7 or note 5 or note 8, network branded devices display that as 5 bars, my unlocked devices display the same db signal as 2 bars... I get the 210MBps download on -96 ish db.. I hope you didnt rip it apart just because you saw 2 bars and it was actually unable to connect... you should flash back everything stock and confirm.. even on this phone I have seen it lower to 2 bars after changing systems around, but still always same average connection strength
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
yes quite sure. When i press at the correct angle on that antenna connector the signal strength jumps up to about -78 dBA in the same spot, which matches my Note 5. Bars mean almost nothing since they are adjustable. Remember that dBA is logarithmic so a 10 dBA reduction is 10x stronger signal.

And I did flash back to stock, the only thing that changed were the bars, as on stock the values they represent are different, and it uses a 5 bar icon instead of 4 bar icon. Again, bars basically mean nothing. Actual signal strength is the only apples to apples comparison.
[Samsung Galaxy Note 8 Questions and Answers] DJC_SP:
If you don't care about root, than must try Batman Custom Rom. You will flash with it, the TMB CSC and will get all T-Mobile stuff. I did it and it worked like a charm.

PS-: I know, Batman Rom is made for the Galaxy S8. What I mean is there must be a Note8 compatible like Batman Rom.
[Samsung Galaxy Note 8 Questions and Answers] iraqgsm:
will it work with NOTE 8?
[Samsung Galaxy Note 8 Questions and Answers] DJC_SP:
Not the Batman for S8... It was just a comparative and you must look for a N8 specific Rom.
[Samsung Galaxy Note 8 Questions and Answers] iraqgsm:
oh ok thank you
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
So after trying to debug some other issues I was having (mainly with xposed and some other tools) and flashing a bunch of stuff here and there, I seem to be where you are. Every reboot so far has reconnected me to wifi calling. but if I disable it, it can't be enabled again until the reboot.
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
Do you still have the status bar icon when it is connected? I haven't been able to get it to show up. I'm starting to understand a little bit of what logcat is telling me, and if I'm correct it seems like there is some kind of permissions issue, I am thinking related to the SELinux rules. I am going to compare the N file with the F file to see if perhaps the F one is allowing something/somethings that the N file does not, as I'm fairly confident that all the software components are in place with this current patch version.
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
Nope, I've lost that entirely.
[Samsung Galaxy Note 8 Questions and Answers] gundal:
Did you see the post I made about DR.Ketan rom..

I experienced the same issue as you guys (wifi calling wouldnt enable) with the stock rom,

restoring my DRKetan /system backup seems to have fixed it

I highly recommend you either, look into the DrKetan rom for our device and see what other files are missing between a diff of that device and our N.

If you are just gonna try out the DRK rom first to see if wifi calling will work on your TMO device, make sure you download the zip, open it up, add your CSC to the omc folder and change the sales_code.dat to TMB and add TMB to the sales_code_list.dat and the SW_Configuration.xml and then flash that and it should confirm if that rom has the bits necessary to get your wifi calling going..
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
I did, and the point of this thread is to get the wifi calling working with the N variant so we can just add a patch on top of our stock ROM, rather than needing to flash a full 950F ROM

The current status of my zip adds what I believe are all the missing components from the F variant ROM that the N lacks, but adding those files alone does not seem to completely make the difference up. On an F-based ROM you can just add the typical OMC and T-Mobile wfc-related apps and libraries and everything works just like it was a T-Mobile phone. Several pages back I explained that I ran a compare utility between my N /system/ folder and an F /system/ folder and have updated the patch to add the few files that were 'missing'.

Adding the 'missing' files to an N base is allowing the wifi calling to connect on a fresh reboot, but the status bar icon isn't showing after an initial flash, and if the wifi disconnects for any reason, wifi calling will not reconnect until the device is rebooted so there is still some piece to the puzzle that I have not yet figured out.
[Samsung Galaxy Note 8 Questions and Answers] gundal:
I was only suggesting that as a test to verify that the files you need are in the difference between the roms.. not as a final solution to getting wifi working on stock, if that worked you could then run a diff between drk rom and stock N.
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
Yes I understand, that's what I am saying. I did that and we know that everything works if you use an F-based ROM. I already added the 'missing' files which are present on the F based ROMS, but not on our N variants.

The two bases are about 95% identical, but the F variant has a few apks and libraries that are not on the N, and a bunch of apks are "different" data-wise but as far as I've seen so far the only thing that is functionally different is the libsec_ril since the F one is for a dual-sim device.
[Samsung Galaxy Note 8 Questions and Answers] gundal:
ohhh my apologies! I read most of your thread but not all of it.

I was under the impression you never got WiFi calling to consistently work through boots, even with the full F rom.

If you already know a full F rom will do it, then its just probably one or two more librarys.. keep at it, you will find it!

I am very happy to have it all working.. now I am gonna be devoting my time to possibly modifying samsung pass to still work without knox.. would be nice..

HAH! renaming samsung pass from /data/app/com.samsung.android.samsungpass-1/base.apk to base.apj

removed the need for samsung pass to use biometrics for

web login and samsung account... so its back to working how it used to work for the Note5 and 7 where samsung pass was not required and you could login to websites with fingerprints!

thats a win for me..
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
No worries, I almost never keep up on threads that pass about 3 or 4 pages :)

It's a bit odd because if we use an F-based ROM and add the T-Mobile CSC stuff literally everything works exactly as it would on a real T-Mobile phone. You can toggle wifi calling on and off, disconnect and reconnect wifi, etc and it has no issues.

Right now the only leads I have with getting it working correctly and reliably on the N base is that there may be some differences in the SELinux config between the two, as I am seeing logcat errors stating that the the tmowfc app and I think epdg are trying to call a system process without a qualified user, which doesn't make sense to me since they are system apps and any system app is/should be running AS system.
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
I thought the FD was a dual sim and the F is not?
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
could be, my F comparison has been with Nemesis ROM since it is technically stripped-down from full stock but still works perfectly with the small T-Mobile CSC patches.

The libsec_ril there switches my phone to dual SIM mode if I swap it out (even on an otherwise 950N ROM)
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
Sidenote: when on the stock korean rom, bixby vision allows you to pull shopping results (albeit from a useless korean site). Once I flash your patch, unlike other regional things (like the weather service), the shopping aspect of bixby vision disappears entirely. AFAIK in the US it's supposed to work with Amazon. any ideas?
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
Might be a regional thing with the app. You could try replacing it with an American version and see if the behavior is any different.
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
Haven't been able to track one down (if there is one). Not sure if it's just the bixby vision app too as part of it's functionality is accessed directly from the camera app :/
[Samsung Galaxy Note 8 Questions and Answers] Comp1demon:
I am using the NEMESIS ROM on my N950N and Bixby Vision works fine with Amazon Shopping.
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
so I've been comparing logcats of my Note 5 and this Note 8, the only big standout so far is that the 8 is using IPv6 addresses for the wifi calling connection attempt, where the 5 is using IPv4 which I wonder if this may be part of the problem. I'm not sure where that is set though.

Is the "F based roms on N devices cripple LTE" rumor dead now? I know several people were saying this happened but I haven't heard anything since. At this point I'm seriously considering flashing nemesis.
[Samsung Galaxy Note 8 Questions and Answers] shouren04:
I was going to ask earlier when KT first started having the LTE issues. Think the missing 1700mhz AWS band on the N has anything to do with it? Tmobile does use this band but I'm not sure what the purpose of the AWS band actually is.
[Samsung Galaxy Note 8 Questions and Answers] Comp1demon:
I am going to assume it came from the nemesis rom or the ATT CSC I flashed. Not 100%. When I was on stock rom, everything was Korean like yours.
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
if the missing band was involved, why would LTE work fine on it until an F based rom was installed, then permanently be crippled?
[Xiaomi Mi 5 Questions & Answers] Oyongx:
Hi, i've got a question here. Im currently own the xiaomi mi 5 while my friend owns the Mi 5s. That friend of mine wants to get his device flashed to Lineage OS 14.1. But when i go to there, i saw the status of the ROM marked as "testing". While mi 5 lineage os 14.1 marked as "nightly".

What's the difference between these two? I know the difference between Alpha, Beta, Nightly, and Release Candidate, but i never heard of "Testing".
