LG Aristo 3 & 4 Secure Startup Bypass – Metro lmx220 lmx320

While setting a screen lock on LG Aristo 3 (Plus) & Aristo 4 plus, we get an option to add an extra layer of protection.

 

 

This is similar to a screen lock but is more secure. To enable this, we need to select the option”Require password to turn on the phone” during setting up a screen lock password.

Until you enter your secure startup PIN/Pattern/Password you won’t be able to get calls, messages, notifications, and alarms.

You can see I’m stuck at the Secure start-up screen on my Aristo 3 (Plus) and Aristo 4.

We get 30 attempts to unlock the screen.

 

After every 10th attempt, we need to restart the phone and try again.

When all the attempts are exhausted, we get an option to factory reset the phone.

You don’t have to wait for 30 attempts to reset the phone. Follow the below guide to bypass the secure startup screen on LG Aristo 3 & Aristo 4 Plus –

 

How to bypass secure startup on LG Aristo 3 & Aristo 4

 

When stuck on the secure start-up screen, first of all, you should power off the phone.

Long-Press the power button and tap “Power off” to turn the phone off.

While the phone is off, press the volume down & power button to boot the phone.

As soon as the phone vibrates (or when the LG logo appears on the screen), release the power button, and hold it again.

Now, keep holding both the keys until your Aristo 3/4 is on the “Factory data reset” screen.

 

The above screen is known as the Recovery Mode.

In this mode, the touchscreen doesn’t work.

We need to move up and down with the volume rocker and select an option with the power button.

Move down from “No (Exit)” to “Yes” and press the power button.

Again move down from No (Exit) to Yes and hit the Power Key.

This will initiate the factory reset process.

The phone is being erased now.

Wait for a while until you’re on the “Welcome” screen.

Use the “Forward Arrow” to proceed further.

 

We need to connect to a Wifi network to move ahead.

Tap “DON’T COPY” on the “Copy apps & data” page.

This brings us to the pattern lock page. We get an alternate option “USE MY GOOGLE ACCOUNT INSTEAD”. Hit this option.

Now, we are on the google verification page. You need to enter the last-synced Google account (on this device) to get past this FRP lock screen.

If you don’t remember the Google account details, follow the below guide to bypass the LG Aristo 3/4 FRP lock –

How to Bypass Google Verification on LG Aristo 3 & 4

 

To bypass the Google lock on Aristo 3/4 we need another phone to set up a SIM card lock. 

I’m using my LG Aristo 2 to lock a SIM Card.

If using an LG android phone –

Go to Settings > General > Lock Screen & Security > Set up SIM card lock as shown above.

Toggle on the “Lock SIM card” option.

Enter the current PIN. I’m using a MetroPCS SIM Card. The default PIN for Metro/T-Mobile is 1234

A confirmation message flashes on the screen “SIM card lock enabled”.

Now, remove the SIM from LG Aristo 2 and insert it in your LG Aristo 3/4.

 

Use the SIM ejector tool to remove your Aristo 4 SIM tray.

Insert the locked SIM card and push the SIM tray in its slot.

On Aristo 3, the SIM tray is located under the battery door.

After inserting the locked SIM, it’ll ask for the PIN code.

Enter 1234 and hit the tick mark.

Now, swipe down the screen starting from the “Not signed in” notification towards the bottom of the screen. 

Follow the arrow as marked in the above screenshot.

If done correctly, you’ll see the notification panel shortcuts on the top.

Long-Press the “Bluetooth icon”.

This brings us to the Bluetooth page.

Turn on Bluetooth. We have to receive an image file from another device.

Use another device to send an image file. 

I’m sending the “LG Aristo 2 home screen screenshot”  file as shown above.

Open Gallery, and hit the “Share” option.

Choose the sharing medium as “Bluetooth” and send the file to Aristo 3(Plus)/4 plus as shown above.

 

Accept the image file on your Aristo 3(Plus)/4 and hit the “3 dots” icon on the top-right corner.

Tap “Received files” to view the received file.

Tap the image file to open it. By default, it’s set to open with the Gallery app.  We need to open the file using the “Photos” app.

Hit “Photos” and select “ALWAYS” or “JUST ONCE”.

“ALLOW” access to the “Photos” app and hit the “Share icon” to send this image file.

Use “Email” as the sharing medium.

 

Allow access to the Email app and choose the Email Provider as “Microsoft Exchange”.

On the Microsoft Exchange page, enter any email id in the “EMAIL ADDRESS” blank field.

The “MANUAL SETUP” option is enabled. Select this option.

This brings us to the “Server settings” page.

Scroll down to the last option on the page. Add a “Client certificate” by tapping “Add”.

An “Attention pop-up shows up on the screen. We need to add a secure screen lock to proceed further.

Hit “CHANGE” to accept this request.

Add a screen lock. It can be a Pattern, PIN, or Password.

This new screen lock will replace the old Secure Start-up lock. 

Choose “No, thanks” on the Secure start-up page and hit “NEXT”.

I’ve added a PIN lock 1234

Confirm the screen lock and hit “OK”.

A confirmation text flashes on the screen “Screen lock has been changed”.

We are all done. We have replaced the old screen lock with a new one. 

Now, we have to go all the way back to the “Welcome” screen.

Keep going back using the back button.

Now, we are on the Welcome page.

Use the forward arrow to move ahead.

Hit the “DON’T COPY” option and select “NEXT”.

Once again, we’re on the screen lock page, but this time we know the screen lock PIN.

Verify the Screen PIN we just added a few steps ago i.e. 1234

As we verified the screen lock PIN, we get an option to skip Google sign-in.  Hit Skip to proceed further.

Now, follow the on-screen prompts to keep moving further.

 

 

Accept Google services Terms and conditions.

Tick the respective checkboxes on the “Legal documents” page and hit “NEXT”.

Accept the T-Mobile terms and conditions.

 

Select the Home screen style and hit “DONE” to reach the LG Aristo 3 (Plus) /4 Plus home screen.

We have successfully bypassed the secure start-up screen on LG Aristo 3 (Plus) / Aristo 4 Plus.
