What to do if Galaxy S10 lock out after an update | won’t boot up or open up

If your Galaxy S10 lock you out after an update and you have no idea how to proceed, any of the solutions below might help. Learn what to do in this situation by following this guide.

S10 lock out after update fix #1: Unlock device using your Google account

Some Samsung Galaxy users reported that their Galaxy S10 acted weird after installing the latest update by asking for a password to unlock the screen. This occurred even if the users themselves were not using a password at all. The thing is, your Galaxy S10 do have passwords although you may not be actively using it at this time. This password can be for your Samsung account and/or Google account. In some cases, using either one can unlock the device. Make sure to try either one to see if this will allow you to unlock the device.

For security reasons, there are only a number of possible attempts allowed to unlock any Android device using a Samsung account or Google account credentials. Make sure that you are absolutely positive that you have the correct password for either account before unlocking the device. To do that, try to log out to your account first using a web browser in another device. To see if you have the correct Samsung account credentials, visit their sign in page: https://account.samsung.com/.

To see if you have the correct Google account credentials, visit https://accounts.google.com/servicelogin. Be sure that you are using the Google account added to your phone.

If none of the passwords from both accounts work, do the rest of the suggestions below.

S10 lock out after update fix #2: Restart device

Restarting your Galaxy S10 might work in this situation as well. You must do this troubleshooting steps if using your Samsung account or Google account won’t help. There’s a couple of ways to restart your device. Try restarting it normally first by pressing the Power button to access the boot menu. Then, select Restart option and see if that works.

Some users have reported that they are unable to even access the boot menu so what you want to do in this case is to perform a soft reset instead. Simply press and hold the Volume Down button and the Power key at the same time for 10 seconds or until the device’s screen turns on. This simulates the effect of having disconnected the battery from the device. If this works, this may unlock the device.

If doing the regular restart won’t help, then try this:

  1. Press and hold the Volume Down button first and don’t release it.
  2. While holding it down, press and hold the Power key.
  3. Keep both keys held down for 10 seconds or more. 

The second restart procedure tries to simulate the effects of removing the battery pack. On older devices, disconnecting the battery is often an effective way in fixing unresponsive devices. Hopefully, your wifi troubles will get fixed by this procedure. If nothing changed though, proceed to the next suggestions.

S10 lock out after update fix #5: Restart to Safe Mode

If your Galaxy S10 lock out after update issue remains at this stage, the most likely reason for the problem may be a system glitch, which unfortunately, may only be fixed by a factory reset. Instead of wiping the phone right away with a factory reset, we suggest that you try to see if you can let the phone run to safe mode first.

Smart Switch can be installed on a computer or to another phone. If you have a computer and want to save your files to that device, then you need to install Smart Switch to it first. 

These are the steps to install Smart Switch on your computer:
