Sometime ago, I used Xperia Flashtool to flash a DE variant of Kitkat for our Xperia Z, but after that flash my phone don't recognize anymore the Sim Card!
It's possible that I've wiped something important? I tried Xperia Companionto restore the stock firmware but the SIM doesn't work anymore.
Have you any ideas of what may gone wrong?
Also the battery may be done, because when it reaches 0% level, when booted up requires to "optimize" apps and that takes about 5minutes/10minutes :(

Thankx you

It SIM-Locked, you'll need to unlock it over at your carrier. Flashing doesn't lock SIM, it just means it had a tripped firmware.
Previously it had the Central Europe firmware, or maybe Italy's one if it had that. I used my Sim on it before the flashing :/ Now if I put the SIM into it, it reboots because it detects, but when rebooted, no sign of life

    I just restore the firmware with Xperia Companion (10.7.A.228.R1E) but I plug into the Sim, it reboots and then it says no SIM inserted, it only reboots if you plug or unplug it :(
    Wifi and NFC works good.
    You should try and FLASH the original firmware
