thing's very wierd. IMEI can be seen,everything is fine, when plugged in my orange sim card it just said "mobile network not available". The signal strength is fine and can be seen. I tried an O2 sim card, a talktalk (vodafone) sim card and they both worked fine. both of my 2 orange sim cards didn't work on this phone, but they worked fine on my other 2 phones.
latest update, just flashed orange stock rom KJ4, got the same problem.
tried manually connect to orange, got notice that "unable to connect, try later".
some more detail:
every time when I flashed a new rom, always a notice saying "can't access to "/system/csc/ORA/system/". Tried *#272*imei#, there was no optional CSC available.
does anyone know how to repair it? thanks!
