I am working on creating Odysseus bundles for 4,1 on 933/4. Here's what I learned so far:

For ASR: I do a branch from beginning of failed signature instruction to beginning of passed signature instruction. I check in IDA for correctness, and afterwards I run ldid -S

For iBEC: I am using ih8sn0w patcher with new boot args, and it's patching the a) the shsh verification 2) debug-enabled branch 3) updating boot args to "rd=md0 cs_enforcement_disable=1 -progress"

For iBSS: just running patcher without any arguments will patch the shsh verification

Why is ASR making my life difficult?
