I had the same problem with the vivacity/crescent. Power on green and logo only. Vol down + power went to FTM. Tried everything, nothing worked, then I tried yr recommendation for Dead Vivacity http://www.modaco.co...-dead-vivacity/. Worked a dream! Thanks!
not sure the key combination for TPT on vivacity.
Have you tried a TPT? that is: image.bin in image folder on sd card.
Just unsure of the key combination, try turning on the vol+ and vol- pressed all together.
make sure you have the right TPT file...
Failing that, you can boot ubuntu (linux) off a usb memory stick or hard drive (temporarily bypassing windows). Google it.
If you did that and copied the adb and fastboot programs to a folder on the usb drive (before bootup) plus the recovery.img you could do it that way.
(all else fails, bring the phone to me!)
Edit: normally different drivers are needed for the phone when in FTM mode as opposed to the normal running mode.
Edit 2: Have you looked at this guide: http://www.modaco.co...-dead-vivacity/
