Hello all. I have looked in many forums and tried so many times to unbrick my N9, but haven't been successful.
My problem started when I issued the "Clear Device" option (my phone was perfectly ok before this, I just wanted to clear personal information). I left the phone working and when i checked back after 30 mins or so, all I could see is "Nokia" on a black screen, nothing happened, so I turned off and on the phone several times, until I realized something was wrong, my phone wasn't working, and I needed to flash it. I had never flashed it before.
I used navifirm to get the firmware for my actual product code (059L698) and winflash to flash it. I have tried on 3 different computers (32bit and 64bit), and downloaded the firmware file twice on different computers. It didn't work.

I haven't found any solution or similar error anywhere. I have also tried several other firmwares (with higher variants, mine es 299) and in all those cases I got the downgrade error

This is the error sequence I get.
