Samsung GS2 - assistance needed
I have a Samsung Galaxy S2, following are the details:
Model # - SGH-I727
Android Version: 4.1.2
Baseband Version: I727UCMC1
Kernel Version: 3.0.31-844945
The phone was bought last year (February) and is still under contract but out of warranty. 3 days back, it started showing "no sim error" without any apparent physical damage. Here are the steps I took to resolve the issue:
1. Restarted the phone
2. Removed the battery and the SIM and then restarted the phone
3. Shut down the phone for over an hour and did a restart
4. AT&T replaced the SIM
5. Did a factory reset and data wipe (after pressing the volume button + power in shutdown state)
None of the above helped and I am kind of losing hope. The phone is out of warranty and is not eligible for upgrade yet. So, before I shell out $$$ to buy a new phone , I wanted to come to you and see if there's anything else I can do?
I have heard that rooting might help? If yes, can you please show me how - I am not that technically inclined but I can follow steps pretty well and cohesively. If rooting fixes the issue will AT&T cause troubles (like block the SIM, etc.).
Eagerly awaiting some suggestion/advice.
