I have the N920I on AT&T and desperately want WiFi Calling to work because it's an essential feature for me. I bought the S7 Edge and hate it, but before I sell it I'm trying to get WiFi calling ported over. Here is what I've accomplished so far.
Copied over apks of all apps known to be related to wifi calling
Changed CSC to ATT
vsimservice crashes repeatedly, rendering the phone unusable
adb logcat reveals
Code:
Didn't find class "com.sec.internal.vsim.VSimServiceApp" on path: DexPathList[[zip file "/system/framework/imsmanager.jar", zip file "/system/framework/secimshttpclient.jar", zip file "/system/framework/vsimmanager.jar", zip file "/system/app/vsimservice/vsimservice.apk"],nativeLibraryDirectories=[/system/app/vsimservice/lib/arm64, /system/app/vsimservice/vsimservice.apk!/lib/arm64-v8a, /system/lib64, /vendor/lib64, /system/lib64, /vendor/lib64
Does anyone have a clue how I can solve this? It seems to be the last remaining piece of the puzzle.
Hi all, with this guide I will show you how I adapted yakapa40's CSC change guide to work for my dual SIM Note 9 to get it from Singtel CSC to T-Mobile USA
All credit goes to TEKHD
and yakapa40 and bober10113
if you want to go to T-Mobile just flash this. Confirmed this works on FD devices on o3 Dr. Ketan Rom
http://tekhd.com/detonator/#tmodetonator
I will be testing VoLTE and Wi-Fi calling and speeds shortly.
VoLTE and Wi-Fi calling confirmed worked on T-Mobile with my 512GB FD!!!!!! TEKHD Detonator
DO NOT FOLLOW BELOW GUIDE: I tried to do this on o3 Dr. Ketan rom it did not work. If you follow past this line you are at your own risk.
I accept no liability to what you do to your device, however this worked for me. Please backup your device in full (ALL PARTITIONS with TWRP)
You will need a rooted device!!!!
First you need to download this to convert your dual sim device to USA variants
USE ES file explorer (it retains the permissions of the files, I will also show all the permissions of the files too)
SM-N960U OYN multi CSC ( ATT BST CCT CHA GCF SPR TMB USC VMU VZW XAA XAS )
by default : XAA
CROWNQLTE_USA_SINGLE.pit
SM-N960UOYN1ARG6_odm:
https://drive.google.com/file/d/1cF4_l6aIGvGwtxg1O9cHonEFiCEzJaR8/view?usp=sharing
This was all done on Dr. Ketan rom, with ES File Explorer
So follow these instructions substituting TMB for ATT or whatever you desire if you don't want the TMB
DISCLAIMER: For some reason I haven't got wifi calling working, if you know why please share!!
Only add the CSC folders you need: if switching to USA CSC with above file copy the XAA folder, and the desired CSC I used TMB to /odm/omc/
(to modify this to a different carrier than TMB go to the CSC pack you downloaded and check that SW_configuration.xml file for ATT info or whatever you like)
with a file explorer open system/odm/omc/SW_Configuration.xml
line : <NbCustomer>83</NbCustomer> : change value+1 (84)
add or copy/paste line : <CustomerData src="/Customer/TMB/customer.xml" />
<OmcInfo> add or copy paste :
<OmcCode>
<CustomerCode>TMB</CustomerCode>

copy /paste folder TMB and XAA to /odm/omc/
open /odm/omc/sales_code_list.dat
add TMB to the CSC list
open /odm/omc/sales_code.dat
and edit to the desired CSC, I changed mine to TMB
edit the code file in /odm/omc with text editor to the desired CSC file
edit the CSCVersion.txt file in /odm/omc/ to the CSC pack system build # if you downloaded the above pack for TMB or USA carriers copy this : N960UOYN1ARG6
edit the build.prop in /odm/
in the first line you will have to change your build version to N960UOYN1ARG6 (if you are switching to the USA csc pack with the above link)
skip the second line
on the third line make sure its like the picture
on the fourth line just remove all text until the = sign and then just add your CSC
on the fifth line just make sure it says FALSE
I had to create this file with es file explorer (click the three dots, and create new file. Then name the file omc_region
inside the file you created just type the CSC group you downloaded (above link for USA csc pack is XAA group)
good job doing all that stuff to your CSC
now navigate to /efs/imei/
there are supposed to be four files and all need to be edited.
in /efs/imei/ the first file mps_code.dat needs to be changed to the desired CSC, I put mine to TMB
in efs/imei/ i had two omcnw_code.dat files I just deleted the second one and edited the first one to the desired CSC which was TMB for me.
edit prodcode.dat in /efs/imei to the new csc package, the USA build # N960UOYN1ARG6
the last file you need to edit is replace_code.dat in /efs/imei
change it to the desired CSC, again mine is TMB
booooom!!!!! if you have made it this far with my bad guide give yourself a pat on the back, and reboot your phone! Hopefully the new splash screen will show and you can use your FD device in the USA with the CSC you wish!!
Here are the permissions on all the files that were modified incase a different file explorer doesn't retain the original file permissions or you had to create files
Here enjoy this final picture showing the csc which was actually listed as MMI or something in settings now is TMB

@jgoorn You are the the best:laugh::laugh::laugh: i will try this soon. can i ask why you have such a low signal ? i see you have only 2 bars
hey thanks for the write up.Did you get wifi calling to work by chance.I changed my SM-N960N csc to AT&T everything working but cant get wifi calling to work its not greyed out or anything.I get a message IMS service has stopped which I believe is something message related then just keep telling me to try again later,any fix yet,THANKS AGAIN

glad someone was able to make a cleaner version of my dodgy instructions.
also note that editing SW_Configuration.xml is meaningless because you can simply copy paste it from the region/carrier omc folder you want to change to. infact you can simply copy over whole contents of omc from new region tou want to change to and replace thise files on phone. then, go edit them to specific carrier codes since stock files point to region code instead of a specific csc. take the opportunity to delete all unneeded subfolders in omc since they are from other carriers. ( replacing files = lost oermissions so remember org permissions and set them back)
by replacing ALL omc files you end up really changing all files to that specific carrier/region and not use partial old original csc and part new csc. just a suggestion as to not end up with a franken-xsc but hey do what ever works for you...
in odm HWRDB are keyboard languages matching region. so it can also be a good thing to copy over if your are missing keyboards.
also people, stop quoting first post... takes 2 minutes to scroll.
OP maybe use the spoiler function to hide them pictures..
also for any one else wanting to get their own files.
grab stock fimware you want to change to from where ever,
extract odm.md5 with 7zip then use the utilities at the following link to unpack and then uncompress img( the bigger 300mb or so file in there is the one we want to work with) so use the 2 tools here to get access to the actual odm/omc/csc folders and files:
https://1drv.ms/f/s!AhXVLDDj8g3AgdJZvVHcXqqlKgy0dg
now you can change to any region/carrier. if they update then you can repeat OP procedure with the latest files. so you're not stuck using old out of date files.
This is great, but what if the benefit of doing so if voLTE AND wifi calling don't work after

I got volte, it says HD+ on my calls. Also I now have 4g LTE and not H+. Something has happened. I'll try bober's idea of copying all the stuff and see if WiFi calling gets enabled.
Still low signal and slow speed?

Inside my newly built house (10 years) the insulation is so strong I get poor cell service. At another family member's home I get no service. I'll try when I am outside to post speed test results.
Also FYI: my brothers S8 on T-Mobile (branded USA) gets the same reception as my Note 9 inside.
Damn you guys live in lead houses? [emoji3] I appreciated it, I don't wanna drop 900$ for slow LTE speeds and poor signal even outside.

It has come to my attention that you can just copy the folders "omc" "etc" and just reboot. I also missed the copying etc step in my above guide so please do that too!

Very odd. Something is definitely missing / not configured for yours. I need to get to an area with decent cell coverage to actually test my 3 different devices from the same location.

Try fast.com, you'll probably get different results
This internation note 9 has better bands support for tmobile usa than my pixel xl. So it will be an upgrade for me.
when using speedtest app, you might want to try and manualy select a server instead of letting the app do it. i have a preferred server that i know always yeilds the fastest and most consistent result for my region.
On a PC, test a few and figure out which is the best and then use that one to test on your phone
also, i believe csc only has apn settings and nothing more to help signal.In the new csc youd want to switch to there is a sipdb folder that might or might not have anything to with reception.In the IT field, SIP is related to VoIP so these files might be needed for Volte.
in phones original firmware, cp is the modem files so if a new version is out, you guys might want to flash CP in odin to get on the latest.( not CP from your desired csc but for your actual device.
on my part, had done my own procedure successfully a while ago.
Anyone else having issues with current guide should try to copy EVERYTHING(except lost and app folders) from odm. I had covered this in not so much details but with keeping in mind to copy over everything and looking at the example pictures and with logic and knowledge, confident anyone can get their csc up and running properly:
