If they can its a closely guarded secret haha, ive been through everything bar a jtag but thats only because i wasnt interested in it.
Been through all the drives bar the ones that need trace cuts.
Uncrippled (not unbanning) a banned xbox which requires soldering wires to tiny holes on the motherboard of the xbox and to a connection to connect to your pc, then reading the nand chip about 15 times to get two matching pairs (which takes a long long time)
unbanned profiles and harddrives, lot of work, lot of reading.
Softmod, i wish lol
