The first problem was —ARM processors speak a different byte-order language than x86 chips. Then came the memory constraints ; chdman assumed a PC’s virtual memory, but Android killed processes that ate more than 1.5GB of RAM. She rewrote the block hashing algorithm to stream data instead of loading entire discs into RAM. She plugged her OTG cable into her phone,
