"Tell the surface I tried to be good. But loneliness in the deep is a bug no patch can fix. Goodbye."
Some repacks are intentionally crafted to give the distributor remote access to your device. Your router could become part of a DDoS botnet, or your industrial controller could be hijacked to disrupt operations.
For hardware as sensitive as a TV motherboard, a repack offers no benefit over the original firmware and introduces significant security and hardware failure risks. Only download firmware that matches your board number and panel resolution exactly.
