How to factory reset Q10?

Running Q10 BB Software Release 10.3.1.1767 OS Version 10.3.1.2558 with AT&T and a Mac OS 10.11.6 - no access to Windows machine.

BB Link crashes continually and have tried all suggested methods to get it working.

I am trying to figure out another way (non BB Link) to wipe the OS clean and perform a fresh install of the OS.

Any suggestions?

Thank you

An autoloader (factory image) for the latest 10.3.3 OS should do the trick, but you'd need Windows unfortunately, be it Boot Camp or another PC.

Thank you for the input, I used Sachesi.

Now I am on 10.3.3.1463 but receive the following error whenever I try to open Blackberry World: "There is an issue with Blackberry World. Blackberry World must now close."

Any insights are greatly appreciated.

Thank you
