I believe they would've been much better off if they abandoned their Meego and Maemo platforms and doubled down in Symbian. Symbian was still going strong and cutting off in favor of Windows phone was obviously bad for their customers. So customers left Nokia. If they'd stuck with Symbian they'd still have the low end of the market today. Who knows down the line some opportunity could've come up to take advantage of its characteristics as a tiny mature non-appstore centric embedded OS.
