I have extrated cryp32.dll from my cooked rom 29315 AKU 126.96.36.199.37 (enable/fix SHA2) using ROM Extractor. Maybe files can be copied to windows folder with total comander.
The good News: total comander can copy/replace the files. But (Bad News) then the HD2 would not start. I tried your files and I extracted the crypt32.dll & crypt32.dll.0407.mui files from my modyfied stock-rom. Both the same result. Only hardreset or new flashing could help.
Other option could be recmod the crypt32.dll & crypt32.dll.0409.mui folders with this tool: http://forum.xda-developers.com/showthread.php?t=576027
What is recmod for?
Do you, or anyone else have an idea?
