Result: Generates key files (e.g., AESbootKey, RSAboot_priv.txt) needed for the next steps. 2. Decrypting Images
If your recovery.img or boot.img is encrypted, use the secure_partition.py script or the aescrypt2 binary.
Usage: python secure_partition.py .
Alternative: Use aescrypt2 directly to toggle between encryption (0) and decryption (1). 3. Unpacking and Repacking Once decrypted, you can modify the internal files.
Unpack: Run the unpack.py script against your .bin or .img file to see individual partitions.
Modify: Edit the files within the extracted folders (e.g., changing the build.prop or adding root binaries).
Pack: Use pack.py to reassemble the modified files into a flashable format. 4. Flashing the Firmware
Move the final modified .img back into your main upgrade script or use the MstarUpgrade.bin creation tool to generate a single file for USB flashing. 💡 Pro Tips for the Updated Version
Performance: Recent updates often focus on performance optimization for larger 4K firmware files.
File Extensions: When decrypting, some users add a .dec extension (e.g., recovery.img.dec) to avoid overwriting original files until they are ready to swap them.
Verification: Always verify signatures after repacking to ensure the TV's bootloader won't reject the modified image.
