How I disabled amber alert on LG G8X(or any LG) phones

Since CRTC shoved a massive penis down everyone's throat by broadcasting amber alerts at presidential level, thus normal cellphones has no way to disable this alert other than turning off the phone or turn off LTE which is not feasible IMHO.

Thus after months of researching and trials, with the aids from xda-developers, I had successfully disabled the emergency alerts on my LG G8X phone which is a very popular budget flagship phone on RFD and thus felt it's imperative to share the method with you fellow redflagdealers.

BASIC concept:
Since CRTC is broadcasting missing children 1000 kilometers away through presidential level, thus a normal user on Android cannot disable it. One would need ROOT privilege to be able to editing system CMAS broadcasting preference file by putting a "false" flag in that particular xml in order to disable presidential alert level.
However, in order to root your phone, you would need an unlocked bootloader, and in order to unlock the bootloader, you would need to access fastboot in your phone which is very easy for other phones(Samsung, Xiaomi, etc) but LG..... LG fastboot is disabled from manufacturer and in order to be able to enable LG fastboot, one will have to flash a stolen LG engineering adb file to your LG phone in order to access the fastboot. I will now showcase the procedures which is extremely difficult and long for LG phones and please bear with me.

CAUTION BEFORE YOU DOING ANYTHING: this flashing procedure is extremely dangerous as it uses an engineering adb file for which unexperienced user will very like brick the phone. Make sure you read this procedure 100 times and understand the concept fully before processing, I AM NOT RESPONSIBLE FOR YOUR LG PHONE BECOMING A BRICK!

Windows 10 x64 is what I used.

1. I use the reference guide from xda-developer as a way to gain bootloader unlocking and root by the following link:

https://forum.xda-developers.com/t/guid ... e.4221793/

2. before doing anything, turn off your screen lock such as fingerprint scan, swipe, keycode or anything form of security measure as this will cause an infinite looping once you had flashed the engineering LG adb file, and will brick your phone, don't say that I haven't warned you! ALSO ALL YOUR PHONE DATA WILL BE WIPED BY BOOTLOADER UNLOCKING


3. once you had successful bootloader unlocked and rooted your phone with Magisk through above xda-developers procedure, now it comes to the fun part, Use any terminal app (I use Termux), and type su, and Magisk will prompt you to grant root access to Termux, click allow:

4. copy /data/user_de/0/com.lge.cmas/shared_prefs/com.lge.cmas_preferences.xml to /storage/emulated/0/Download/ folder :

5. plug your phone to a computer and copy that com.lge.cmas_preferences.xml file to your computer, open any editor and modify, the presidential xml field to be false, or any alerts that you hated to blare at 2am in t he morning:

6. now copy this modified xml back to /storage/emulated/0/Download/ on your phone, and use Termux with root access to copy and overwrite back this modified file back to /data/user_de/0/com.lge.cmas/shared_prefs/com.lge.cmas_preferences.xml

7. reboot your phone, and go to emergency alert app to verify that presidential (or any alerts) has been disabled:

8. Enjoy your peace nightly sleep forever! :)

CONS:
1.bootloader unlocked LG G8X will no longer has finger print scanner working, only pin, swipe will work.
2. bootloader unlocked LG G8X will require extra steps in Magisk to make google pay (or any secure payment app to work), the following is what need to have google pay to work on bootloader unlocked phone:

Using Universal Safety Fix (download Universal safetyNet fix from github)

No additional Magisk module required

Install Zygisk (that will allow denylist):

I enforced DenyList on:

Google Pay

Afterwards, in this order, I cleared the data of

Google Play Store

Google Play Services

Enjoy your google pay!

3. OTA update no longer works, thus disable software update, and in developers option, disable auto-reboot for system update. For bootloader unlocked phone, upgrading requires side loading firmware through fastboot.

Depending on Android version, certain firmware will allow Presidential Alert to override your silence option since Android presumes Presidential Alerts are serious for things such as Nuclear blasting, or mega earthquake, and never fathomed dickhead CRTC would use it to broadcast amber alerts.

btw, now I can leave my phone on without going into silent mode so that my family members friends can reach me in real emergency.

I grew up in a communist country(yep by judging my name you had guessed which country it is) that invasion to people's privacy life was norm back in the 80s, but couldn't believe that such totalitarians controlling, deplorable method is even executed here in Canada by CRTC yet you sheeps don't even revolt against it.

I've only received a few amber alerts ever. They are not enough to be annoying.

Lol. Imagine thinking that being subjected to an alert *maybe* 3 or 4 times a year when a child gets abducted is the same thing as a totalitarian communist regime.

Then why don't you go and live in a commie country? It was always the small pet-peeves would get on your nerves back in the 60's during my parents childhood, the GOV would stuck up a loud-arse speaker in your home that will broadcast useless propaganda news every morning, or announcing certain criminal at large, or emergency crap such as flood, fire with blaring loud announcer's voice at 2am in the morning woke your whole family up, the exactly same way as CRTC's amber alert system. Nope you couldn't unplug or destroy the speaker, as you would be prosecuted for infringing to the "safety of common people and the communist party".

I found it odd that in Canada, the media always biasly found excuses to blame anything that's taking place in commie countries, but being oblivious to the exactly practice when it was executed by CRTC, and folks sheepily bite the bullet and carry on with CRTC's invasive amber alert bully.

TBH, sometimes the commie country has a lot more freedom of speech than Canada as you can talk whatever shxt (racist, misanthropist, misogynst, you name it) as long as it's not against commie party you would be fine, unlike Canada, you gotta be careful with whatever you said OR femi-nazi would give you a hell when you didn't pay attention to gender neutral terms when delivering speeches.

DEATH to totalitarian control of CRTC!!!!!

I have to agree these alerts are annoying, wish they could be disabled on iOS.

For IOS, you got screwed up by Steve Jobs once at purchasing, and another arse-hole raping from CRTC during normal use...... Jailbreaking was no longer possible and you gotta live up with the amber alert crap.

For Android phones, the procedure is mostly easy as phones such as Samsung, Xiaomi are extremely easy to get bootloader unlocked, but not LG, I had tried for over 3 months and once got my phone to an endless booting loop due to a small issue with Magisk incorrectly patched the boot, never never again will buy another LG due to their practice of closing up Fastboot access by default and thus made the whole process 100times more painful...

Again: "this child has been abducted in your area and we believe they are in danger, please keep an eye out" messages coming a handful of times per year is very different from "all hail the great leader, we must obey his every command" every single day. You're combining a false equivalency *and* a slippery slope fallacy here.
