Alcatel OneTouch Fierce XL getting Windows 10 Mobile update to build 10586.545


If you’ve got an Alcatel OneTouch Fierce XL with Windows 10 Mobile, the time for you to update has come once again.

T-Mobile’s Fierce XL is now receiving an update, and as you can see in TmoNews reader Joe’s screenshots, the update bumps you to version 10586.545. As for what’s included, Microsoft’s changelog doesn’t mention any mobile-specific tweaks, so this cumulative update is a bit of a low-key one.

While this update may not sound like the most exciting thing ever, it’s still wise to grab it as soon as you can to ensure you’ve got the latest software and security patches. If your Fierce XL hasn’t yet updated to 10586.545, you can manually check by going into Settings > Update & security > Phone update > Check for updates.


Thanks, Joe!
