OS 10.3.1.2480 in the form of upgrade BARs have appeared on the Internet for the BlackBerry Passport. This particular OS is supposedly meant to fix the screen flicker bug that many Passport users have come across. Thanks to Bla1ze on the CB forums, these upgrade BARs should be sideloaded in whichever preferred method you like. Read the instructions carefully.
These are the OS .2480 upgrade files for the BlackBerry Passport only. It is suggested that this release has the Passport screen flicker fix in it. In order to load it onto your device, download Sachesi, plug in your device, go to the install tab, hit the install folder box, choose the presumably extracted folder and let it install the files until it installs all 70, unless there is files you specifically decided to leave out.
If you get warnings, they’re safe to ignore assuming you actually read the fact these are for the Passport only and you’re not loading them on some other device. At this point, there is no autoloaders, there is no files for other devices and the possible issues/additions aren’t fully known plus, you need to already have 2243 or 2267 installed as you’ll be overwriting it with these. You dig? Alright then. Get to it.

PS: You should probably reboot or some shiznit like that after its all done.. or don’t. I don’t care either way lulz!
Hat tip @jmznvs
There you have it. The instructions could not be any clearer and for those that have the Passport, let us know if the issue has been resolved!
