executing the Kernel Patcher mannualy gives

looking at the script the issue seems to be the lack of ios 16 handling

    "$dir"/Kernel64Patcher work/kcache.raw work/kcache.patched `if [ "$ptraceDisabled" = "1" ]; then echo "-t"; fi` `if [ "$aslrDisabled" = "1" ]; then echo "-c"; fi` `if [[ "$version" = "15."* ]]; then echo "-e -o -r -b15"; fi` `if [[ "$version" = "14."* ]]; then echo "-b"; fi` `if [[ "$version" = "13."* ]]; then echo "-b13 -n"; fi` >/dev/null

i changed that 15 and -b15 to 16 and -b16 and now i am stuck here
