Restore your device to its original state if it is corrupted, infected by malware, or bricked.
Remove bloatware or unwanted apps that consume storage space and battery life.
Customize your device according to your preferences and needs.
To do any of these things, you need to download and install a new stock rom on your device. However, not all stock roms are created equal. Some are official and some are unofficial.

Release the buttons when you see the Android logo and then press the Volume Up button to enter recovery mode. Use the Volume buttons to navigate and the Power button to select. Choose "wipe cache partition" and confirm. Wait for the process to complete and then reboot your device.
Factory reset: This will erase all the data and settings on your device and restore it to its factory state. To do this, follow the same steps as above to enter recovery mode and then choose "wipe data/factory reset" and confirm. Wait for the process to complete and then reboot your device.

If your device is unable to connect to the network, recognize the SIM card, or display the IMEI number after installing stock rom, you can try the following solutions:

Check IMEI number: Make sure that your IMEI number is valid and not blacklisted or blocked by your carrier. You can check your IMEI number by dialing *#06# on your device or by looking at the sticker behind the battery. If your IMEI number is missing or invalid, you can try restoring it using a tool like IMEI Repair Tool or Samsung Tool Pro.
