Ya, pero al principio cuando intente el downgrade , creo que le cambie la radio en alguno de los pasos, por eso no me va el wifi.
o eso creo.

No lo creo, si lees en el foro/enlace para cambiar la RADIO tienes que usar unos comandos y renombrar las radios al formato que te especifica (no es tan sencillo)

Download the your choice of radio for the HTC Sensation.
Make sure the filename is PG58IMG.zip exactly or it will not work and copy it to the same folder as adb (the /platform-tools folder within the Android SDK folder).
Asegúrese de que el nombre de archivo es "PG58IMG.zip" exactamente o no va a funcionar, copielo en la misma carpeta que el ADB
Connect the HTC Sensation to the computer via USB.
On the computer, open terminal and run the following commands:

adb push PG58IMG.zip /sdcard/PG58IMG.zip

adb reboot bootloader

The HTC Sensation will reboot & usually boot into fastboot. Pressing the Power button will put the device into the bootloader.
