Patch irobot apk using apk-mitm

1. Enable USB debugging on the phone

2. Enable adb on PC

3. Connect phone to PC via USB

4. Pull roomba apks from the phone

   $ adb devices
   List of devices attached

   $ adb shell pm list packages
   ...
   
   $ adb shell pm path com.irobot.home

   $ adb pull /data/app/.../base.apk com.irobot.home.apk
   $ adb pull /data/app/.../split_config.arm64_v8a.apk config.arm64_v8a.apk
   $ adb pull /data/app/.../split_config.xxhdpi.apk config.xxhdpi.apk

5. Download xapk from https://apkpure.com/irobot-home/com.irobot.home, extract files into irobot-xapk folder

6. Copy manifest.json

   $ cp irobot-xapk/manifest.json manifest.json

7. Create new xapk

   $ apack irobot.zip com.irobot.home.apk config.arm64_v8a.apk config.xxhdpi.apk manifest.json

8. Patch irobot.xapk with apk-mitm

    adb uninstall com.irobot.home

11. Install apks with install-multiple

    $ adb install-multiple com.irobot.home.apk config.arm64_v8a.apk config.xxhdpi.apk

Use mitmproxy to get BLID and password

1. Install and run mitmproxy

   $ mitmproxy

2. Open port 8080

   $ sudo iptables -I INPUT 1 -p tcp --dport 8080 -j ACCEPT

3. Follow instuctions to configure proxy on the phone with installed CA: https://medium.com/testvagrant/intercept-ios-android-network-calls-using-mitmproxy-4d3c94831f62

4. Run irobot application, login

5. Select request to /v2/login in mitmproxy: check robots dict in response, BLID is entry's key and password is in the password field

I am stuck on step 7. Also where do you get apk-mitm from?

@Danny2100 apack is just a linux tool to create archives. You can use any other tool that can create irobot.zip archive with 4 files in it: com.irobot.home.apk, config.arm64_v8a.apk, config.xxhdpi.apk and manifest.json

apk-mitm is a tool from here: https://github.com/shroudedcode/apk-mitm. Not sure how to install it on Windows though.
