If successful, this outputs a <project>.vxp file.
To use a conversion tool, simply follow these steps: Convert .jar To .vxp UPD

Set your target output deployment to the specific ARM architecture of your target phone. Build the project using the MRE compiler. A platform-independent package for Java class files and

Once you have a .vxp file, most modern feature phones (like Nokia S30+ models) will not run it unless it is to match your phone's SIM card. Build the project using the MRE compiler
Most MRE development and compilation tools are designed strictly for Windows environments.
This article explains what these file types are, why a simple conversion doesn't exist, and the methods developers use to achieve this goal.
