After Soft Reset, the most useful forms of troubleshooting on LG K40 are Safe Mode, Recovery Mode & the Download Mode. Soft Reset is nothing but a normal restart. It’s a quick fix and works most of the time.
However, for bigger issues as soft brick, overheating, app crash or being locked out due to a forgotten pattern or pin, we need to use the advanced modes of troubleshooting which are safe mode, recovery mode & the download mode.
Let’s deal with them one by one.
1. LG K40 Recovery Mode
The recovery mode is useful when you’re locked out due to a forgotten pin, pattern or password. You should use recovery mode to Hard Reset your K40 only in case you’re unable to reset the phone using the “Settings” app.
Within the Phone Settings, we can do a Factory Data Reset by going to “Settings” < “Restart & Reset (General Tab)” < “Factory data reset”.
If locked out, then follow the below procedure to boot your K40 into Recovery Mode –
Let’s bypass the Google Account Verification on LG K40 LM-X420 using the latest and easiest method. With this method, we can bypass FRP on K40 without using an app or computer.
This tutorial would work for all the K40 variants including K40 MetroPCS lmx420mm, K40 T-Mobile lmx420tm, K40 AT&T lmx420as, Factory Unlocked K40 lmx420qn, K40 US Cellular lmx420qm, & K40 Spectrum Mobile with model number lmx420qm6.
On doing a hard reset via Hard Keys, i.e. Volume Down & Power Button on LG K40, we need to go through the Google verification screen to complete the factory reset process.
This is Google’s Factory Reset Protection also known as FRP.
To get past this screen we either need to enter the Screen Lock PIN, Pattern or password (In case the phone had a Screen Lock), or sign in with the last synced Google account on this particular device.
The good news is that it’s quite easy to bypass this verification screen on K40 using this latest hack.
Follow the below screenshots to bypass the Google Lock on LG K40 –
How to Bypass Google Verification on LG K40 LM-X420 2019-2020
As a first step, go back from the Google Verification screen to the first screen of the setup wizard.
Let’s divide the whole process into 4 steps –
STEP 1: Gettings Access to the Youtube app via the Accessibility Settings
We are back from the Google Sign-in page to the “Welcome” screen as shown above.
On the “Welcome page” look for “Accessibility” and open it.
A pop-up appears asking for confirmation. Tap “SETTINGS” to get access to Accessibility.
We are now on the “Accessibility” Page. We’ve to select the last option, “Switch Access” on this page.
To open “Switch Access Settings” tap “SETTINGS” located at the bottom-right corner.
On the “Switch Access Settings” page the first option is “Help & feedback”. Select this option to move ahead.
Again select the first option on the Help Page i.e. “About Switch Access for Android”.
The next page has a Youtube video on “How Switch Access Works”.
Tap on the video. A “3 dots” menu icon would appear. Select this icon.
This gives us 2 more options on the screen, Watch Later & Share. Select “Share” to proceed further.
We are using this share option to launch the Youtube app.
Now tap on the “Youtube video URL” or “3 dots” to gain access to the Youtube app.
On the youtube page, below the video, you’ll find the “Share” icon. Tap on it.
STEP 2: Adding a Secure Screen Lock using the Email app
We are given various options to share the video. Among the listed options, choose “Email”
Give the email app the necessary access by hitting “ALLOW”.
Once again we’ve to click “Share” and then “Email” as done before.
When you’ll choose “Email” for the 2nd time, it’ll ask you to select the email provider.
Among the listed email providers select the 3rd one i.e. “Other”
There are 2 options on the next page, Email Address & Password.
Just type any email id to highlight the “MANUAL SETUP” option.
Now “MANUAL SETUP” is enabled. Select this option.
Select the account type as “Microsoft Exchange” and tap “NEXT”.
We are now on the “Server Settings” page.
The last option on this page is “Client Certificate”.
Tap “ADD” to add a certificate.
An “Attention” pop-up appears on the screen. It says we’ve to change the Screen lock to a secure one. Tap “CHANGE” to accept the request.
The next page is the “Select Screen Lock” page.
There are 3 screen lock options which are Pattern, PIN, and Password.
Set either of them. Choose an easy to remember screen lock PIN, Pattern or Password and note it down.
I’m setting up a Screen PIN on my K40.
STEP 3: Reboot phone, finish the setup wizard and land on K40 Home Screen
After adding the screen lock it takes us to the “Fingerprints” page. We can skip this step.
Now, we’ve to reboot our K40.
Long-Press the Power Button & select “Power off and restart” to reboot your phone.
Once again the K40 is on the Welcome Screen.
Use the “forward arrow” to move ahead.
Select “DON’T COPY” on the “Copy apps & data” page.
When prompted, enter the screen lock PIN, Pattern or Password you added in the previous step.
We are again on the Google Sign-in page. However, it’s different from the Google Lock / Verification screen. Here we get the skip option.
If you wish, you can also add a Google account at this stage ( the last synced Google account is not needed).
When the “Skip account setup?” pop-up appears again tap “Skip” to proceed further.
Now we are on the “Google Services” page. Here we have to accept the Google services terms and conditions.
Follow the On-Screen prompts & keep moving ahead.
Tap “OK” on the “Review additional apps” page.
The next page is the “Legal Documents” page.
Tick the checkboxes as shown above and hit “DONE” to land on the K40 home screen.
STEP 4: Changing the Screen Lock
We have successfully bypassed the Google account / FRP on LG K40.
At this stage, if you wish you can change the screen lock.
Pull down the notification bar and select the “Settings Icon” as shown above.
Go to the “General Tab” and select “Lock screen & security”.
On the next page, choose “Select screen lock”
Enter your PIN, Pattern or Password we just added a few steps ago.
Choose a new Screen Lock among the listed options. You can also add a Fingerprint or Face Lock as your new screen lock.
