[Q] [P] Problem after upgrade - sim card not found

Hi there,
a friend of mine just got a used xperia p. He inserted his sim card and it worked.
After that he started the current software update. And here is the point. Right after the update no sim card is recognized any more - always says "please insert sim...".
Service menu says everything except sim is locked with 5 possible tries.
I just made a downgrade using flashtool which seemed to free the phone again according to service menu - but no sim card is detected.
An update using flashtool leads to the same problem (locked).
What can I do?
Thanks in advance.

When Sim is in: IMEI and baseband not recognized, also, no service.
with sim taken out: Emergency calls available, imei and baseband detected.
tried reflashing, downgrading, nothing helped.
did you find any fix?
please try with different sim and post if it works or not.
Tried with 3 different cards of different providers. No Solution yet - any idea?

Inserted sim card but no service or registered network

I bought a used galaxy s3 that seems fine except that i can't get it to work with my sim card. I always get the searching & not registered on network when trying to dial. The sim card works fine on other phones. the phone is running android 4.3... Any idea of what could be the problem and how to fixx it?
Are you sure that you phone isn't sim locked?
If it were sim locked you would get a request for the unlocking code at boot. Most likely the phone has been tampered or broken, either wrong modem or efs folder corrupt.
Search and read for the available fixes.

SGS3 Got "invalid sim card" message

Hello,
yesterday I flashed on my SGS 3 an S6 port. My Sim card works fine before the flash. I had an S5 port in there. So, I got an message that my Sim card is invalid. I should type my PUK. So I did it. I got an error message: "invalid puk. Opportunity to center 10/0". I flashed it back to Stock rom and I have the same error. I tested the sim card on the S6 from my Girlfriend and It gave me the same error. What can I do before I buy an new Sim card?

Help with Samsung Win i8558 IMEI clash!!!

Hello Win'ners
Please I have this Samsung Win i8558 I got from a friend and would like to use my both lines in it (Not actually as a smartphone as I already have a Note 4) Runs on 4.2.2 but here is the problem I have with the device!
If I insert one SIM card in either slots... It reads and gets signal for the Network SIM. (either Sim1 or Sim2)
But if I slot both SIMs in both slots... It would give a "No sim card" error even when it would shows the SIM Network names under "SIM Card Manager" in settings but would not detect signal.
So I put in one SIM in sim1 and checked the IMEI via *#06# and it came up. I put in one SIM in Sim2 and checked the IMEI and found out both slots uses the same IMEI number.
If I mount both SIMs at same time and check the IMEI , it would give "Null/Null"
Any help on how to solve this problem as I have 2 network SIMs I want to use on it.
Thanks.
SOLVED
I solved the issue by flashing a later build via Odin!
Now I need root!
