my sister tried to root this phone with completely no recollection of how she got here.
the phone displays "the software update failed. make sure your phone is connected to a computer and try again" right after the "sony expria " screen.
i tried the yellow reset uptton but no vibrations came with that.
once connected it says "upgrading, do not disconnect device from pc" and the software status is official.
not sure how if the computer doesnt even recognize the phone.


every little bit of help is appreciated.

download original ftf file and flash it using flash tool


Would you be able to tell me or direct me to steps in doing so? Sorry I'm a little new to this. I called Verizon and was on the phone for 2 hours. Said they can't help since I'm a previous customer unless I come back to them. I called Sony and they just told me that those Verizon phones are not their problem. I would really appreciate all the help I can get

This should help you step by step. Make sure you have proper drivers installed... you can find them in the flashtool folder. If your phone is saying software update failed plugging it in the USB of a computer should automatically put it in download mode. If it doesn't press and hold volume down when you plug it in.
