(adsbygoogle = window.adsbygoogle || []).push({}); Hey guys, I need help with my Xperia Z1. I tried to flash it, and everything went fine, but when I turned on my phone, it said "Invalid Card. - Emergency calls only." I tried doing an update, but it wont work, it just says "Could not install." Has this happened to anyone else? If so, how did you fix it?

WHAT did u flashed? Did you rooted the device? Stock Rom or Costum Rom? ^^

I recently found out I did something completely different... I realized I had actually downgraded my Z1 to 14.1.G.1.518 using Flashtool, I still can't find a fix though.

I don't think you can downgrade...
I also wanted to downgrade my Z but yeah it failed.
