BF3 "insert sim card"

[Kenas]

I am trying to do a reasearch on why does this appears in a BF3.

I´ve reached the conclusion that it could be for various reasons.
First of all I think that it could be the TEH file. But how can you recover the TEH file if the phone have been full flashed with a downgraded version ?
Secondly it could be because it is downgraded. So simplest solution would be to flash it again with the newest version but still same problem appears.
It could be also the TECH zone of the phone... but how can we recover this ?

Pls any advice or comment I would be glad to read it and help us mutually.
