One of the most common modifications is integrating Google Apps directly into the ROM. Instead of flashing GApps separately, you can merge them into the system/ partition during repacking. This creates an all-in-one ROM ZIP that includes both the OS and Google services.

Because of the lack of source code, stable upstream releases (like official LineageOS) are incredibly difficult to build.
Why repack instead of building from source? For older devices like the T113, building a modern Android version from source requires extensive hardware-specific device trees, kernel sources, and considerable computational resources. Repack approaches allow enthusiasts to create functional custom ROMs more efficiently by leveraging existing builds as a foundation. Tap 7 times until a toast message says
A custom ROM is an alternative operating system built for your specific device. A typically refers to a modified version of an existing ROM (either official firmware or a community build like LineageOS) that a developer has optimized. For the SM-T113, repacks usually focus on:
Browse to the system/app/ and system/priv-app/ directories. Remove any applications you don’t need. For the stock T113 ROM, this includes many Samsung-specific apps that consume precious storage space. Removing them can free up hundreds of megabytes of internal storage and reduce background processes.
Because the device operates with only 1GB of physical RAM, virtual memory management is vital. Use kernel management applications (such as SmartPack Kernel Manager or Franco Kernel Manager) to configure a zRAM disk space allocation of approximately 256MB to 512MB. Adjust the Android Low Memory Killer (LMK) profiles to a "Aggressive" configuration to proactively terminate background processes before the system stutters.

Google Play Services is the heaviest background framework on legacy devices. Replacing standard GApps with MicroG (an open-source clone of Google frameworks) reduces background RAM consumption by up to 200MB.
