sin usar una PC, existen varios métodos "manuales" que aprovechan vulnerabilidades en el proceso de configuración inicial. Métodos recomendados para Samsung A03 Método de desconexión de Wi-Fi (Hotspot)
This write-up details a "pinning" exploit method commonly used on Samsung devices running Android 11. Unlike older methods requiring a PC and specialized software (like Odin or FRP tools), this method exploits the native "Sim Pin Lock" feature to force the device into a race condition, allowing access to the Settings menu to bypass the verification screen.
If the "No PC" method fails, technicians typically use a "Repack Combination File." This is a modified engineering bootloader flashed via Odin that disables the FRP check permanently. However, since the prompt specifies "Without PC," this method is not applicable, but it is important to understand why users search for "repack"—it is the fallback solution for devices with updated security patches where the SIM Pin exploit described above has been patched by Samsung.
