[Sprint Samsung Galaxy S7 Edge Guides, News, & Disc] godpowerrr:
Switch apps, many of terminal emulators<< not called that but thats what they are. Search Terminal IDE or anything really. The problem relies at SuperSU's granting property you have; Grant/Default. In order for precision it is smart to Grant SuperSU's authority to accept applications asking its permission to be used, to be allowed at all times. There is a feature for this to be prompted for your security/device being taking over via hacked/stolen.. make sense? In all, make SuperSU access to be granted always because it can be hidden sometimes/removes the reason your keyboard is glitching. I know this because its happened to me. Termux is a really good app and what i use for android sending su commands, etc.

However, the only problem with that application is the exit feature not explained. If this is the app you want to use or try out... after applying in Termux:

su [enter]

govtuner [enter] *Can't be applied until 3 minutes after last boot of your device.. GovTuner will tell you this and will just need to wait.

//Display of your cores/threads will be showin in green + parenthesis.. usually 4

Then a prompt for GovTuner which displays all your CPU settings currently and settings willing to change will be there for your sake.

SINCE GOVTUNER's Developer [MENTION=5321318]Debuffer[/MENTION] rewrote his whole code for the Kernel Modification.. things will be different...BUT better!

-I use 1200 seconds for my PERFORMANCE profile( The screen I said would appear after govtuner ..Type 3 and then enter)..the 1200 is for injection per

seconds of the properties of this profile.. it is listed in things to change and NOW currently it is disabled. <<vv

^^You don't want performance strings/device enhancement being applied every 3 mins because this device can't handle the battery and cpu at the same time.

So change that factor and choose (4) as performance level in one of the modes you can change at Govtuner's default home page.

Back to the exiting

:

type exit followed by enter

exit

exit(may or not be true)...

prompt will appear saying something like press enter-which would be on your keyboard OBV- and thats it to exit.

A reboot would be good and settings/strings/cpu changes will stay as you changed them until removal via Termux/Terminal Emulator, etc...

exit, enter basically

WiFi CALLING for SM-G935U

*

May or May Not WORK (Worked for me-just READ-) Not for BEGINNERS

This is for Sprint ONLY! But may work if you have these files in /system/ and /system/csc folders

*

------------------------------------------------------​

I have some news to bring. Upon dismantling files, experimenting, with Trial & Error..I have discovered a way to receive WiFi Calling.

This has been tested only on my device so far-which worked... though I don't know for any other similiar carriers :

Boost/Metro, etc. I am sure it would work if on Boost mobile/Virgin Mobile if you change you r<NbCustomer></NbCustomer> value to:

2 (<CustomerData src="/Customer/BST/customer.xml" />)

(Boost)

3 (<CustomerData src="/Customer/VMU/customer.xml" />

(Virgin Mobile)

That being said I shall Inform you;

So what I did to conquer WiFi-Calling for the SM-G935 U MODEL of SPRINT's S7 EDGE category was:

[*]Applied root exactly as I've posted recently.

[*]Moved files from system/csc/spr/system over to main directory[system/csc] The reason I did this is because I did a lot of thinking and I realized if SM-G935U can be used totally on SPR Network or Sprint's SM-G935P Network*Basically any phone or service involved with Sprint will/would connect to this domain by default... then why not apply 310120 in build.prop and see if it stuck. It did... and being off of the XAS network string is a relief in regards to speed and connectivity bounching to/from the network....but applying /spr crom csc folder led me to...[*][Overwrote files and completed a reboot. Wiping Cache is always recommended but not always necessary. *Wise if deleting files/replacing files ;)]

[*]->When device reached home sceen, a prompt approached giving a message, I can't give verbatum because i skipped it though accepting by pressing 'OK'...will reboot every single time....[the message pertains to SIM CARD Properties being changed and it asking me to insert default SIM CARD that came with one and to reboot]

[*]So I changed SW_configuration.xml from XAS (Targeted to 4 in my xml file) was switched to SPR (Targeted to 1 string in my xml file)-Sent via adb+usb and rebooted but obviously can be done after previous step i just mentioned(where i messed up).

[*]Everything was fine. I turned on my Location allowing me to enable the WiFi Calling. Everything seemed just like Sprints main firmware-SM-G935P.

[*]Being that I was done verifying the accuracy of my hyptohesis*at the time, I tried to reset back to XAS (Chameleon). << vv

^^ THIS IS WHERE I MESSED UP BIG TIME ^^; files I changed were system/csc/

Customer.xml

,

others.xml

,

default_code

, and

sales_code.dat

..

WHEN ALL I SHOUL'D've done was,

[*]I should've changed my build.prop's string entitled, "ro.cdma.default_numeric=

310120

" to "ro.cdma.default_numeric

310000

" changing it from SPRINT's [SPR]

Default

[*]Network to [XAS]

Chameleons

[SPRINT's

SM-G935U

Default

Network].

[*]Does this make sense and expand your ability to grasp the knowledge of two but most importantly same equal Networks..However SPR being faster/more adequate to sticking?

Basically to receive WiFi calling for SM-G935U you will need to root, apply files from system/csc/spr to system/csc and overwrite these files.

Change

SW_configuration.xml to 1

[

SPR

] in /system/ folder by using ES Note Editor inside app or by opening

Notepad ++ on [PC]

*Use

Notepad++

, it is the best computer program and most accurate for xml/any file texts files for oganizing code/text. On android-different and can produce errors in the file leaving it corrupted.

Then reboot. If you're willing to try and trust me then it is on you .. but you will have WiFi Calling *Leave Location on and WiFi Calling Enabled before final reboot.

*Change Strings below

(Only to be done if beginning step didn't work):

<PublicName>

SM-G935U

</PublicName> to: <PublicName>SM-G935P</PublicName>

---

<CSCName>G935UOYM</CSCName> to:

<CSCName>G935PSPT</CSCName>

...

But leaving this string alone

: <NbCustomer>1</NbCustomer> *

SPR

*

[COLOR="RoyalBlue"][B][SIZE="5"][U][U]SW_Configuration.xml[/U]'s default setting to SPR Network ([U]XAS would be[/U] G935UOYM4BQF3[4])[/U]:

<?xml version="1.0" encoding="UTF-8" ?>
<SW-Configuration>
<MobileData>
<PublicName>SM-G935U</PublicName>
</MobileData>
<CustomerDataSet>
<CSCName>G935UOYM</CSCName>
<CSCVersion>4BQF3</CSCVersion>
<NbCustomer>1</NbCustomer>
<CustomerData src="/Customer/SPR/customer.xml" />
<CustomerData src="/Customer/BST/customer.xml" />
<CustomerData src="/Customer/VMU/customer.xml" />
<CustomerData src="/Customer/XAS/customer.xml" />
</CustomerDataSet>
</SW-Configuration>[/SIZE][/B][/COLOR]

--------------------

See how SPR is

1

, XAS is

4

.

You can change system/build.prop's numeric value to 310000 if you want but I didn't and don't know the outcome.

The string <NbCustomer>1></NbCustomer> determines your selection between the 2 (4 total-Sprint/Boost/Virgin/Chameleon)

^-String coorelates with system/csc/folder(s)<< but may sometimes only work by copying the files located from that direct/actual folder back into main csc folder.

---------------------

Hope this makes sense and PM or mention me if you need any help...also if anyone wants to try the WiFi Calling and be the second verification it would be much appreciated so I can create or [MENTION=5825961]jtash01[/MENTION] can add to his thread.

The reason I said I messed up ^ like above is being Sprint locked my SIM Card making me have to go in and have it added via their end. Little do they know i have another SIM Card. If you read this post properly and wanting to try then since I've warned you and this shouldn't be a problem

If you have the time to go into a coorporate store or maybe even retail then they can give you a new SIM Card for WiFi calling to be added to SIM Card and I am guessing added via Update Profile in System Update for SM-G935U firmware to have that feature without a possibility of your card being locked. I know this because I am not a good story teller :P But yea thats what I was told by Sprint live chat. 2 options.
