So yesterday I updated to the following:
After which I have no mobile service, I behan with the general culprit which is the SIM card and followed the following troubleshooting steps:
1. Reset network Settings
2. Reset APN
3. Restarted my phone
4. Re-insterted the SIM card
5. Purchased a new prepaid sim to check if SIM card is faulty
6. Replaced old SIM card for a new one as well
7. Factory reset my phone
Yet, I still don't have any service on my S21FE. It really frustrating and the fact that I can't downgrade a security update which seemed to be causing the issue.
Hope someone could help me out.
Update:
So, I managed to submit the error report for my phone and samsung technical team still hasnt gotten back.
Meanwhile, I decided to visit the service center. I requested for a downgrade but was informed that even authorized service centers cant downgrade the system. They said they would check the system and reflash the update and see if there are any problems. I agreed, ended up paying the amount. They told me that they checked the system with a SIM card and was working fine. Verified the same and left the service center. If this was all it would be great.
Unfortunately, as soon as I reached my office the issue repeated itself. Contacting the service center, they are stating that this might be a hardware problem, clearly when a software update caused the issue. One service center literally suggested to wait for the 6.1 update that will be available in 3-4 days.
Even after paying for their service no resolution. Will keep you guys updated if i find a solution
