So we have a potential API endpoint, let's put it to the test. We're not going to recompile anything yet or do any byte-patching,
let's try a quick smoke-test. Ensure your phone is rooted and you have a variant of Xposed Framework installed (I used LSPosed).
We will need to unarm the SSL pinning present in most apps, including this one, I used [io.github.tehcneko.sslunpinning](https://github.com/Xposed-Modules-Repo/io.github.tehcneko.sslunpinning) module.
-(Note: I know it is possible to repackage the app to do SSL unpinning in most cases, but in many cases, you won't know if it's worth the effort yet)
+(NOTE: Users without root might want to skip to end of article where I showcase unpinning the app manually)
Next, install [AdAway app from F-Droid](https://f-droid.org/packages/org.adaway/) so we can setup a redirection on any network we are on.
Inside AdAway, add a redirection rule for the address we just found and point it to an IP address in your LAN that will run the API server.
Generate a self-signed certificate authority and a certificate signed by it and run a webserver with both HTTP and HTTPS on the API server machine.
```
# Create an ext file containing the Subject Alternative Name (SAN)
-# DNS.1 should correspond to the API endpoint of the app (more info near end of article if you plan on changing)
+# DNS.1 should correspond to the API endpoint of the app.
+# NOTE! If you are changing the API endpoint to a public domain, you can just use a public cert, no need for any of this.
cat > auxbrain.ext << EOF
authorityKeyIdentifier=keyid,issuer
basicConstraints=CA:FALSE
python3 apk-rebuild.py egginc.apk --pause
```
+**NOTE!** IF you do not intend to patch the API endpoint and just want to proceed with AdAway redirecting traffic, you can stop here and press ENTER!
+Proceed only if you own a domain in your control (that is equal or less in length to www.auxbrain.com) and want to use the app without a VPN/redirection.

Open a new terminal window, the script will wait for us to perform modifications, enter the created folder `egginc.apk-decompiled` and `lib`.
We have two folders here now, `arm64-v8a` and `armeabi-v7a`, just as we saw when we pulled the .so file out of the apk earlier. Let's tackle
