Speed up WIFI / LTE By enabling CRDA on Android aka wifi country code (root only) - LG V20 Themes, Apps, and Mods

STANDARD DISCLAIMER: I am not responsible for any damages caused to your phone. Use the mod at your own risk there is no warranty or guarantee.
I found out how to enable the CRDA the correct way on boot. That way the Kernel knows what country your using the phone in. And the Kernel need's to know what power level it can use for the wifi and what channels are okay to use per the FCC. This will speed up wifi a lot, also there was an unexpected side effect from this mod, The LTE on my Lgv20 is 16 MB Per second now as apposed to only 5 or 6 MB Per second. The speed will go up and down depending on how busy the network is.
All you have to do is flash my mod I made in twrp or do it yourself. Just edit your wpa_supplicant.conf file. It should be located in /data/misc/wifi/wpa_supplicant.conf
Find the line that says #country=US or it may say what ever country your in and just comment out that line, remove the # in front of the line. Make sure it's the correct country code like US or GB. Save restart it's that simple. Check with "iw reg get" command.
Country Code List
The twrp mod I made just looks in /data/misc/wifi/wpa_supplicant.conf and finds #country= and just comments out that line. It does not change the default setting. On my phone the Lgv20 H910 the default was set to US but it was commented out so the Kernel just skips over that line of code.
Before installing the mod, in termux type this command. If you get an output like this "#country=US" then you will benefit from this twrp mod. Or it may say "#country=UK" depending where you at.
command:
su
cat /data/misc/wifi/wpa_supplicant.conf | grep "country"
#country=US
The # is what we are removing.
But it if says like file not found, the mod will not work on your version of Android. Make sure to check for typo's maybe you could just copy this in a text file to your phone and copy and past.
then type
exit

To change the default US country code edit "/data/adb/modules/init_crda/service.sh"
Change US to GB country code in all caps then reboot.
That is a very good question and I have provided info on how to change the country code in the main guide.
Also I have made a Magisk Module just for Great Britain that includes the UK.

Your welcome

Hey everyone I just learned some new information on how to set the CRDA on boot. This way we don't need to use the Magisk Modules I made. It works a lot better because the CRDA is set on boot.

Good Question, I only run Oreo on my Lgv20.
Before installing the mod, in termux type this command. If you get an output like this "#country=US" then you will benefit from this twrp mod. Or it may say "#country=UK" depending where you at.
command:
su
cat /data/misc/wifi/wpa_supplicant.conf | grep "country"
#country=US
The # is what we are removing.
then type
exit
exit
But it if says like file not found, the mod will not work on your version of Android. Make sure to check for typo's maybe you could just copy this in a text file to your phone and copy and past.

Yeah I had a Magisk module at one point. But I don't think it will work in Android 12. They changed so many things in that version.

ok ok
In termux type
su
iw reg set US
it should be changed to us now. you can check with "iw reg get"
You need to disable wifi and enable wifi for it to take affect.
You will need to do this every time you reboot.

Yep you did it correct. Then type "iw reg get"
It should say like US-FCC or something like that. Then turn off wifi and back on again and you should be able to get your channel 149.
In the terminal if you don't get an error back that means it worked. So no news is good news haha.
Oh and you don't need to type "type'
Only
su
iw reg set US
iw reg get
exit
exit

That's so odd I don't see how this mod would affect you wifi. But anyway just uninstall it in Magisk and reboot your phone. That will completely remove the mod. It does not make any permanent changes to the os.
