This software is free to use, feel free to modify.

Only thing i ask for is to link this git as a start point of your own modifications.

I am not responsible for any damage done! Use your brain and all will be fine!

Also i will not include any apk to this git! You have to do everything yourself, if you cannot you should not play with stuff like this!

App version 4.1.4 is still work in progress. I would personally recommend using 4.1.3, anyway if you want to use 4.1.4 you can but it has not all patches yet AND the CC check dialog is gone and will not come back (still the fcc patch code is present and working [Spark RC 300FW seems to cause problems but SparkRC 100FW works!])

If you get a message about different region etc. etc after using the FCC patch: YOU HAVE TO CLICK OK!

1. make sure you have dialog installed: sudo apt-get install dialog

2. Download needed tools manually or run the script provided.

   a) Download apktool, rename it to apktool.jar and save it to tools folder: https://bitbucket.org/iBotPeaches/apktool/downloads/

   b) Download sign.jar from https://github.com/appium/sign/raw/master/dist/sign.jar and put it in tools folder

3. Get the apk to modify (ver. 4.1.3), try 'Raccoon, the apk downloader' (Linux/OSX/Windows), you can get it here: http://raccoon.onyxbits.de/, or try a mirror such as http://www.apkmirror.com/, or if you don't trust anyone use this chrome extension (needs MANUAL install into chrome and cannot be found in the chrome-store): https://apps.evozi.com/apk-downloader/

4. RunMe.sh

1. Please copy 'sign.jar' into 'tools' folder, check above for link (if the 'tools' folder doesn't exist, simply create at the same level as the 'PutApkHere' folder)
2. Please copy apktool to 'tools' and rename it 'apktool.jar', check above for link
3. Please install gnuwin32 and copy 'patch.exe' into 'tools' folder, you can get it here: https://downloads.sourceforge.net/project/gnuwin32/patch/2.5.9-7/patch-2.5.9-7-setup.exe
4. Please copy 'bspatch.exe' into 'tools' folder, you can get it here: https://github.com/eleme/bspatch/blob/master/tools/windows/bspatch.exe
5. You may need to install Java Development Kit, you can get it here: http://www.oracle.com/technetwork/java/javase/downloads/index.html
6. Get the apk (ver. 4.1.3), check above for link
7. RunMe.bat (as Administrator)

1. Follow the instructions for installing java and gnuwin32 above.
2. Install .Net Framework 4.6.2 if you don't have it: https://www.microsoft.com/en-us/download/details.aspx?id=53344
3. Unzip PatchAPK.zip to a C:\
4. Add the tools path to your system PATH variable. So add C:\PatchAPK\tools
5. Rename the original apk you are going to decompile to something without any spaces like DJeyeGO-413.apk
6. Launch the app by double clicking PatchAPK.exe
7. Select file, and find your renamed apk
8. Select file, and choose the version of the apk you are patching
9. Click decompile, and wait until it finishes. apk will be decompiled to C:\PatchAPK\decompile directory
10. Select the patches to apply, and click the Patch button. (The dry run checkbox is for testing the patches without applying them)

1. I don't want people flying in NFZ
2. It did not work consistently

If you want to fly in a RED NFZ AND are allowed to AND have problems with them activating your account to do so you should fallback to the firmware parameter change. This was never meant to help people fly in RED NFZ!
