Hello, I just recently purchased my new sim reader, and a SIM MAX 16 in 1 sim card.
I managed to crack the KI on old VoiceStream SIM (Pre T-Mobile days, haha) i had laying around.
heres that info, taken off woronscan (bits emitted for privacy)
Code:
KI : 7F ** C9 ** 1B ** 4D ** EB ** 1C ** 3B ** 02 **
IMSI: 08 ** 01 ** ** ** ** ** **
ICC : 89***************27
after cracking my Ki (which took about 30 minutes, not so bad.. apprently from what i've read it usually takes a good hour or so) i realized i needed to have done it using SimScan provided by Sim Max (sadly, mine was in chinese so i avoided it.) after a couple hours of fiddeling around, i managed to pull up MagicSim which allowed me to manually enter my IMSI, ICC, and KI information. after entering my KI i realized that it would change it. (no matter what KI i entered, magicsim would read it as something else [simmax has some protection on the sim so you cant use 3rd party software i found out later
])
so heres my question:
after trying to erase all enteries, and loading it up into SimScanner, when i try to read/write it says "Invalid Card"..
MagicSim still reads all my enteries properly, and when i pop the sim into a phone it sees all the enteries just fine.. but the KI is wrong so none of the options authenticate properly.
how can i fix this?!
if someone can instruct me as to how i can either use MagicSim, or format my sim to be able to use SimScanner again, please let me know!
EDIT:
i've made some progress i think..
i entered in 00000000000000000000000000000000 as KI and MagicSim outputs 8FD131136E510EA98FD131136E510EA9.
Code:
0000000000000000 00000000000000000
8FD131136E510EA9 8FD131136E510EA9
maybe it splits it into 8 bytes each, and XOR or something on the number?
heres output of 10000000000000000000000000000000:
Code:
1000000000000000 0000000000000000
28C41AB4B2EA2DF4 8FD131136E510EA9
no pattern.. =[
and FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF:
Code:
FFFFFFFFFFFFFFFF FFFFFFFFFFFFFFFF
4646249F559F15BA 4646249F559F15BA
8 byte pattern shows up again!
this is very confusing! =[
