So roms packed with brotli and ext4 (files system.new.dat, system.new.dat.br, etc.) currently not supported.

The main features of jbart tool include, but not limited to the following list:



In this section you’ll be able to deodex all apk and jar files in selected rom. It supports system, vendor, framework directories

Translation parser

Parse your current translation and compare it to the selected language resources (xml) to get the difference - untranslated resources, obsolete translation, etc.


OTA creator

You can create incremental update packages based on two roms by comparing the difference in files in both of them and create a flashable zip


Single file

In this section you can decompile, compile, translate, patch and sign single apk, jar, or even zip files


HEX patcher

Inject translation and resources directly into resources.arsc file, no need to decompile apk files
