Bq Aquaris E10 BRICKED?

Hi peeps, I have a Bq Aquaris E 10 tablet and everything went well until I tried to install a custom recovery with Flashfy. The installation went ok but when I reeboted the tablet to enter it.... I could never enter the system again (I just have stock recovery and boot logo). I am now installing android sdk tools, but I can not finf drievers and the only thing that I can do is enter recovery thrn adb mode where it says ad sideload <filename> only if I could find a signed recovery/system to install it with the stock recovery... I think that no one in this city could repair this... So I am asking fot help.
