I found this solution by  working around with my Samsung galaxy phone. Please follow this method precisely, and if it doesn’t work at the first attempt, try doing it again.

Turn off your phone by holding the Power Button and the Home in conjunction.
While the phone is off, wait for 2 minutes.
After 2 minutes, remove the battery and the SIM card from the phone
Press the Power button and the home button together for 10 consecutive times.
Afterwards, hold the power and home keys for 1-3 minutes.
Next, insert your SIM card and the battery
Turn on your Samsung galaxy.
While your phone is on, remove your SIM card, and then re-insert it. Repeat this five times.
A message will appear saying that you need to “Restart your Phone”- click it.
Finally, your Samsung galaxy should boot up with no errors.

Solution #5.

If the methods above  didn’t work, then the problem lies with your SIM Card. Trying a different SIM card might solve the problem. It worked for most people.
