But the other REPACK—the one that offers "all channels unlocked"—is a wolf in sheep's clothing. It trades your bandwidth and electricity for a few dozen scrambled TV stations.
These $15 DVB-T2 boxes (brands like "MXQ," "Vontar," "Amlogic S905W clones") are sold at a loss. The manufacturers make money via backdoors. The stock firmware is locked down: No telnet, no SSH, no ability to install IPTV apps.
