Older Armadillo App Does Not Break.

Hello,

I have an app that is about a year old I decided to take a look at. PEID reports Armadillo 1.xx - 2.xx. StubPE reports as 2.75a. I have read through Mephisto's information on 3.xx unpacking as well as some of Ricardo's tutorials which were in English that may have given me insight on this.

What I do know of the app is the following:

1. App uses Copymem (dual processes)
2. The ONLY thing I am able to break on is CreateThread and not WriteProcessMemory with which I can Ret F9 2 times and scroll down to CALL EDI to get the OEP.
3. If I clear all breakpoints hard/soft in Olly as well as uncheck ALL Exceptions I can run the app with just F9. There are no exceptions at all even through the enter key/continue evaluation screen all the way to the full app window.
4. Dumping process after copying parent PE Header and looking for Imports with IMPRec I can find almost all Imports in all modules with 14 reported invalid.

I guess at this point I don't know which way to go. The child process seems to be unencrypting itself and I am not completely versed in nanomites which I am guessing is the issue at this point. The dumped child process like I said has most Imports intact and deleting the 14 invalids as well as rebuilding with LordPE of course it will not run. Any help or direction would be greatly appreciated.
