My Samsung phone is locked, need to reset it

Short summary:

  1. Ensure the device is powered off completely.
  2. Press and hold the Volume Up button and the Power button simultaneously.
  3. Continue holding the Volume Up and Power buttons until the Android Recovery screen appears, then release both buttons.
  4. From the Android Recovery screen, use the volume keys to navigate and select the "Wipe data/factory reset" option.
  5. Confirm your selection by selecting "Yes" when prompted.
  6. Wait for the reset process to complete. This may take a few minutes.
  7. Once the reset is finished, the phone will restart.
  8. Set up your phone as you would when using it for the first time, including language selection, Wi-Fi setup, and Google account login.
  9. If the phone asks for a PIN, try entering "0000" as the default PIN.

Customer Replay

the pin request just stays on

It seems that CE0168 is not a phone model but a tablet one. Are you sure it is correct?

Customer Replay

It is an oyster slider mobile

Noted, thanks!
Do you have the Home button at the bottom of the phone?

Customer Replay

If I take the battery out it clearly shows as CE0168

Customer Replay

No it is on the side

Customer Replay

Sorry the Volume button is on the side
I do not know the home button

It is an oval or circle button at the bottom. Do you see it?

Customer Replay

I have just taken the sim card out

Customer Replay

Yes there is an oval button on the other side

Not in the center of the bottom edge?

Customer Replay

Centre of the bottom ia the C button

Noted, thank you!
Please follow these steps:

  1. Hold down the Power button to power off your device.
  2. Press and hold the Volume up button, the Power button and the Home button
Customer Replay

Does the sim card need to be in?

No. If the SIM card is inserted, it may lead to contact deletion on the card.
Let me know if you get the menu screen and what you see here

Customer Replay

Still trying to boot as requested

After step 2, right?

Customer Replay

Yes, just not starting at all now, did start earlier but requested sim Card

Ok, got it. Please try to power on it back by holding the power button.

Customer Replay

just started now, I am recharging at the same time, I think batter is low it is asking for sim card

Do you use the PC or laptop now?

Customer Replay


Do you have a camera on your laptop? If yes, may I ask you to send me a photo of your phone screen?

Customer Replay

I don't use a camera, it is the standard Screen of a sim card stating inset SIM

Got it
I see. Please put the sim card in and dial *2767*3855#
It is a command for the reset.
Try *2767*3855# or *2767*2878#.

Customer Replay

I have put the sim in but the phone is not starting, give me a moment

Customer Replay

getting there, now asking for pin!

Were you able to enter *2767*3855# or *2767*2878#?

Customer Replay

can't call the number without the pin

Try entering the code by just using the keyboard, not trying to dial it.

Customer Replay

I cannot try it as the pin box is on the screen and it will first complete the pen and fail for a third time!

I see. Did you try the 0000 PIN?

Customer Replay

Are you talking about the oyster phone?

Customer Replay

0000 worked! I am certain the phone never had a pin

It is a default code. So is it unlocked now?

Customer Replay

Thanks for your help. It seems fine at the moment yes

That's so good to hear! Is there anything else I can do for you today?

Customer Replay

Why would it suddenly ask for a pin?

Did you restart it before it asked for the code? It may ask for a security code for the SIM card after restarting it.

Customer Replay

I will start it now again, thanks

I’m glad I was able to get that sorted out for you :)
