Has anybody been able to flash a Lumia 925? I've read four different tutorials for Lumia flashing, none of them agreeing in the sequence of buttons pressing; and with each of the tutorials, and after trying no less than twenty times, I always ended up with some error message, "wrong signal from the device", or something like that. And it gives me back the "retry" popup window, or simply exits with error code. The only log I get from the flashing software (Nokia Care Suit) is "recovery failed". I'm using Product Support Tool version 2013.49.3.30, one of the latest, supposedly supporting Lumia 925.
Someone else? Some success flashing this phone? Some hint about what the issue might be?
