How To Guide T-mobile US VoLTE 5G mobile data instability fix with root - Asus Zenfone 9
I was having problems with mobile data through T-mobile in the US that I was have to disallow 5G or else the carrier connection would drop. Sometimes it would reach 4G+, but it would drop the mobile data connection all the time, especially when moving off wifi. I had never seen the VoLTE icon. After I followed the steps below, the VoLTE icon appeared, 4G calling became a settings option, and the mobile data has been working smoothly. Basically I followed this guide, although I wasn't able to use HomerSp's steps to connect to the qualcomm server, and I just used steps 2.1 and 2.2, which is juanappleseed's directions:

Connect to the phone to your computer, open up adb cmd prompt, use adb shell and type su to get admin access. Magisk superuser request will appear on phone to grant. Then send these commands in shell:

setprop persist.vendor.dbg.vt_avail_ovr 1
setprop persist.vendor.dbg.wfc_avail_ovr 1
4G Callling should be a new option in the mobile data settings. After mobile data off and on again, VoLTE and 5G should work and be stable all the time.
I think rebooting the phone might undo everything...

That would suck if it becomes undone after a reboot.
Over the past couple days, have you tested that out?
@Veiranx The VoLTE icon and 4G Calling settings option disappear after reboot, however the 5G mobile data stability remains.
Checking those persist properties with getprop show they are still 1.
After redialing the code, 4G Calling option appeared as enabled, but needed to be disabled and re-enabled to make the VoLTE appear again.
I figured out that *#*#3642623344#*#* is *#*#ENHANCED4G#*#*. Just a note that after entering the code it's fastest to long-press the wifi icon, then select SIM1, and turning off 4G Calling and back on again; VoLTE icon appears shortly after that.
I tried these other props but they didn't work:
How do I turn off VoLTE via adb?
The way to turn off VoLTE through the UI is Settings > Cellular Networks > and toggle "Enhanced 4G LTE Mode". How do I do this same action through adb?

I have been using the app vozapp from the play store, and I not have problems using VoLTE on my Zenfone 9
Customer service has this response: "ASUS unlocked carrier ZenFone devices sold in the USA do not support VoLTE (Voice over LTE) as this feature is currently not supported. We suggest purchasing the Smartphone for Snapdragon insiders if you wish to utilize VoLTE."

[Q] Enabling WIFI channel 14?
I have tried enabling WIFI channel 14 using the code below with no success. Channels 12-13 work fine though. I'm thinking country code JP might be wrong, any idea?
Code:

[GUIDE] USB reverse tethering - All apps working!!!
I've been looking for this for a while finally I got it, this is what I did: - Connect your android device to your linux PC - Enable USB tethering - On your linux box as root (I'm using Fedora 16) Code: iptables -A POSTROUTING -t nat -j MASQUERADE echo 1 > /proc/sys/net/ipv4/ip_forward ifconfig usb0 12.12.10.1 With this you will enabled internet sharing between network interfaces and assign an IP to the usb interface. - Enable mobile data access (3G) on your android - On your Android using adb or terminal emulator Code: ifconfig rmnet0 0.0.0.0 ifconfig usb0 12.12.10.2 route add default gw 12.12.10.1 dev usb0 setprop net.dns1 8.8.8.8 The first line will disable the data traffic through your 3G connection so all the traffic wiil go through the USB - Enjoy All apps works because they see a vaild 3G connection!!! WARNING: If during you are USB connected, the 3g connection is reset, the system will restore its IP and DNS so the traffic will go through this interface you must reset again the IP to 0.0.0.0 and the dns to 8.8.8.8. Maybe one of the devs here could help us to prevent this happened. You can always check the IP values of all interfaces by typing "netcfg" Press Thanks if I help you
everytime, bash: /proc/sys/net/ipv4/ip_forward: Permission denied yes i tried with sudo, same output. using ubuntu12.04 64 bit. all other commands are fine,

secondary problem Thank you very much for your post, this is what I was looking for. I have configured correctly, ubuntu 12.10 and android 2.3.7 (Huawei U8650) but there is a problem. Only works a few seconds, the first moments. In the browser takes more time, but when I open "play store" internet is disconnected. It seems they check applications and stop working, it's strange. Configuration is successful because it works, but only a few seconds ... Seems to prove that internet applications not from the 3g and crashes ... I have broken the wireless on my huawei U8650 and this is the only way I can access the internet Thanks in advance PS: I'm Spanish, sorry for my bad English.

Marshmallow broke tasker function to toggle mobile data?
On Lollipop I could switch data on or off with Tasker using this command: svc data enable svc data disable On Marshmallow 6.0.1 when the command runs in Tasker it stops and hangs. The output is: 09.56.45 /Shell runBackground svc data enable root: true timeout: -1 where on the left of 09.56.45 there is a red dot. The command does not move to the next line. Same with svc wifi enable, svc wifi disable. Any suggestions on what my causes the problem? It used to work flawlessly
Well after googling I have found a solution but I'm not good with scripts so I don't know if the code may cause any damage or unexpected function. The solution is this: Instead of creating a shell script in tasker as this: PHP: svc data enable or PHP: svc data disable make a script as this: PHP: setenforce permissive; svc data enable; setenforce enforcing And change to "disable" for disabling mobile data. Don't forget to "Use root" option. I owe the answer to this post I would appreciate it, if someone with knowledge of scripting could explain the difference on the code above Thanks
[Guide][17-5-2017]Hide Navigation Bar, Status Bar or both(Immersive Mode)-No App
Hi guys, i was searching for a way to hide the navigation bar without any app that will require you buying it or it consuming battery and after finding a couple of threads on the topic i thought of sharing my findings and also as a reference to go back to in case i forget how to. This is also good for eliminating or reducing screen burn caused by the bars on Amoled screens.
Credits go to @jplempka @cabegol @SmartPhoneLover
Type the following commands in adb/fastboot environment (adb shell) on your PC after connecting the phone in file transfer mode and usb debugging is on:
· Hide Status Bar only type:
adb shell settings put global policy_control immersive.status=*
· Hide Navigation Bar only type:
adb shell settings put global policy_control immersive.navigation=*
· Hide Both Bars type:
adb shell settings put global policy_control immersive.full=*
· Back to normal/default state:
adb shell settings put global policy_control null*
--------------------------------------------
Updates: (15/5/2017):
+ Immersive in all apps except certain apps
adb shell settings put global policy_control immersive.full=apps,-"app location",-"another app location"
Notes:
1. You can get the app location by going to "system/data/data" using any file browser with root, the location should start with the app folder name "com.appname"
Ex: com.whatsapp
2. Remove quotation marks(" ")when adding the location of the app also add an apostrophe(,) if you are adding more than one app and when typing the code there is no space after the apostrophe.

By the way this method works on all rom versions i have tested it on Nougat and all commands work. Good
luck:highfive:
-------------------------------------------------------------------
Updates: (17/5/2017):
Apps Identified to not play well with navigation and status bar hidden and how to exclude them(To be updated accordingly):
Apps List:
*Whatsapp(When typing the status bar needs to be there to see what others wrote at the same time)
*Wechat(When typing the status bar needs to be there to see what others wrote at the same time)
*Youtube(When typing the status bar and navigation bar need to be there)
*Hangouts(When typing the status bar needs to be there to see what others wrote at the same time)
---------------
Code: adb shell settings put global policy_control immersive.navigation=apps,-com.google.android.youtube,:immersive.status=apps,-com.whatsapp,-com.tencent.mm,-com.google.android.youtube,-com.google.android.talk
---------------
P.S: If you want to use these commands directly on your phone without a PC you need first to be rooted, next use any shell terminal to insert the code but remove the "adb shell" part.
So in the terminal app for example if you wanted to hide both bars you type the following:
>su
>settings put global policy_control immersive.full=*
Thank you for this info, also I just tested it using Android terminal and it works well. I don't always have PC nearby to test things, very nice.

Click to collapse Hi isaak, to remove the navigation bar without root you need to take the build.prop file from the System folder using adb commands "Pull" and "Push" (If you search online you will find alot of threads on how to use the command) edit the file by adding the code: " qemu.hw....." to it on your PC and then returning the file to it's place on the phone. I am sorry i can't give you a step by step on how to do this because i am travelling, if i have time i might right a tutorial on how to do this. Good Luck

What's the benefit of on nav bar? If no nav bar how do you guys navigate around the OS?
hinds90 said: What's the benefit of on nav bar? If no nav bar how do you guys navigate around the OS? Click to expand... Click to collapse Good question, we use apps like LMT launcher or GMD gesture control instead of the navigation bar which wastes a good portion of the screen. I used both and i love both of them but i think gesture navigation is the future. Now since Nougat update i stopped using both of these apps because it's a headache to simply root and change the build.prop to simply use both apps, instead i opted to hide the status and navigation bar. You should try both apps you will enjoy your phones' screen more. :good:
[Q] change DNS for mobile connection through ADB [7.1.1]
Hi, I'd like to be able to change the DNS for mobile connection via ADB in Android 7.1.1 (OMNIRom). I tried by using setprop but the 'dig' command always gives 8.8.8.8 as the server. I'd like to change that, as I'd rather not use google dns for privacy reasons. I have to say that the 'dig' command is issued in termux. Maybe this terminal emulator uses hardcoded DNSs? Thanks a lot for any insight you can give me. E.
