I'm from the future(already bricked nokia x and x2), download nokia care suite and use
this tool to download firmware by enter product code on back of phone(like th model 059T983) and paste to care suite folder
like this, open nokia care suite > product support tool for store 5 > work offline > file > open product > search rm-98 and select 980 or 981 > programming > recovery > connect phone with 9008 > press start button and wait after done charge phone until see nokia logo(if phone still black screen and can't detect 9008).
I'm find how to fix brick more than 1 day and now mine nokia x and x2 unbick
, I tried qfil for more than 2 hrs but sahara fail.
