Someone please help me. Whenever I'm trying to get update my samsung s10 5g, it shows 'registration failed' prompt. And s10 5g has already gotten Android 12 but my phone is still Android 11. I want to update it. Please help me if anyone knows about it.
Solved! Go to Solution.
Hello, welcome to the Community, and thanks for reaching out. I can see how this is concerning when trying to update your phone to the latest Android version, and getting a "Registration failed" message. I'd first try to update it using Smart Switch:
Smart Switch for Windows https://www.samsung.com/global/download/smartswitchwin/
Smart Switch for Mac https://www.samsung.com/global/download/smartswitchmac/
Step 1. Connect your device to your computer using the USB cable provided with your device, and then open Smart Switch on your computer.
Step 2. If a software update is available, Smart Switch might automatically prompt you to update the software or will display an option to update.
Step 3. Click Update and use the on-screen prompts to download the necessary files.
Step 4. Click OK to proceed. Your device may turn off and on a few times during the update process. When the update is complete, the device returns to the Home screen.
Note: Don't disconnect the USB cable or use your device
If this does not help get the update through, you can also see if a third-party application is causing this behavior: https://www.samsung.com/us/support/answer/ANS00062983/
Make sure to check your Sim is inserted properly in the Sim tray as well, by simply removing and replacing the Sim tray. There is also a possibility there may be something with the Sim card, which your carrier can assist with replacing.
Lastly, I would try a factory reset, after backing up everything. Follow this guide carefully: https://www.samsung.com/us/support/answer/ANS00062029/
If the troubleshooting is not helpful, and you have contacted your carrier to no avail (who are the only ones who are responsible for updates to your end), the phone will need to be evaluated by a certified technician.
