I have successfully rooted my Xperia V 9.2.a.2.5 and tried to install recovery
After installing flash gordon, I selected the zip file, clicked to grant root access to flash gordon, and it showed "Extracting" for several minutes which kept appeared.
I tried to hit "back" on my phone, that "extracting" disappeared, so I hit the "flash now" button.
The app said successful and reboot required. I manually power off the phone, but the recovery is not installed.
Is the "Extracting" message normal??
I havn't put the recovery zip file into the root folder of internal storage
solution: Put it into root folder
