[Xperia Z Q&A, Help & Troubleshooting] Alxhn:
So I flashed the lollipop tft for the 6616 on my 6606 to have the lollipop goodies in my device since T-Mo forgot long ago

that went great, since I tried sim unlocking my device by code, for some reason the lollipop rom would not allow me to enter the digits in the unlocking screen, so I tried flashing the stock rom for my device... that went no where and my device is now saying update failed and trying to flash any rom goes to this message
