Okay, I did some testing. I downloaded all three versions of AJK v4.9 from the dev host links. The NoSwap and AOSP versions install fine. The MicSwap version seems to be corrupt. I have a copy of the MicSwap version that I downloaded in October of 2013, which although it has exactly the same number of bytes at 8,144,957 bytes, has a different md5 sum, and installs fine. Here is the dev-host link to the working version of
AJK v4.9 MicSwap. I'll also make a link for it in the Download Repository. (md5 : 6478BEA9D4B3662C29E431946FC64415)
