[TUTORIAL] How to factory reset and setup/How to fix all OS-related issues on a Blackberry Classic, Passport and Leap! (Includes instructions for how to setup playstore)

So I just bought a blackberry leap. It was a "for parts" device, and needed an OS reinstall. I noticed some people got stuck on this so let me explain how I did it. This does currently work as of the day this is posted.

First, you need an autoloader. Download the corresponding one for your device here: BB10 Autoloaders

Turn off your device, plug it into your computer and run the autoloader. It'll do its job and you should be at the setup screen!

Now I remember some people talking about having to bypass some setup thing, it didn't happen to me, I just set it up normally.

You should be on the homescreen at this point.

The first thing I recommend doing is downloading a version of Firefox. I DO NOT RECOMMEND USING FIREFOX AS YOUR DEFAULT BROWSER, however it can be useful for loading modern webpages. The included browser is perfect for normal browsing, firefox should only be used if a website can't run properly. You can find a compatible version of firefox here: Firefox 68.11.0 (Note: you will need the armeabi-v7a version)

Next up is Google Play Store. While the Google Play Store doesn't serve a super useful purpose, there are still apps that work that can be downloaded from Google Play. This guide here got me all set up (I did this 5 days ago). You may need to use a OTP (One-time passcode, learn more here about how to set up that) to enroll your device in Google Account Manager, Google Settings, and Blackberry Google ID. I recommend you play that as you go and see if you need one or not.

That's it! Play store may not work immediately, I found that restarting the device or waiting a few hours can help.

Hopefully this was able to help someone out! I will be postin an update here with apps from the Play Store that still work on Blackberry 10 (It will probably be a separate reddit post, I will post an update about it here)
