Abstract

This paper explains the operation, goals, and typical implementation of an "auto patch" firmware for devices using the Samsung J730F (Galaxy J7 Pro) U8 bootloader/firmware variant. It covers device background, firmware components, patching targets (bootloader, radio/modem, vendor files, and hidden partitions), techniques used (signature bypass, binary patching, boot image modifications, and OTA interception), risks, detection, and mitigation. The presentation is technical but non-actionable: it focuses on concepts and defensive considerations rather than providing step‑by‑step exploit instructions.
