While holding the key, connect the phone to your PC via USB cable.
The downloaded PAC file might be corrupted. Re-download the firmware package from a reputable high-quality source and verify the file size matches the host description.

High-Quality E1207Y PAC File: Use a tested version (e.g., E1207YDXMG1 or E1207YJPNA1) to avoid dead boot issues.
A PAC file is a container that includes all the necessary components to make the phone functional. A "high-quality" file is typically an official stock ROM that hasn't been corrupted or modified by third parties. It contains: The Bootloader: Instructions for starting the hardware. The Operating System: The core software interface. NV (Non-Volatile) Data: Critical network configuration and IMEI information. Why Quality Matters

An NV data file contains only the Non‑Volatile RAM partition, which holds IMEI, network settings, and calibration data. It is much smaller than a full PAC file. A PAC file contains the entire firmware—bootloader, kernel, system, user data, and NV data together. For severe problems like “service not available” or dead boot, the recommended procedure is to first flash an NV data file to restore network settings, and then flash the full PAC file to ensure the entire system is clean.
The feature transforms standard proxy routing into a performance-oriented network solution. By combining failover redundancy , intelligent bypassing , and **traffic optimization
Inferior firmware often causes the infamous Samsung white screen issue.
