Hello, first time poster long time lurker as they say. Greetings to all. I just purchased an AK100 MK2 (firmware 2.30) a couple weeks ago and have read most of the 539 pages of this thread. After trudging through getting artwork recognized (not always) most everything else has been good save for the same issues others are having with the microsd card locations and the intermittent freeze ups. The odd 500x500.jpg artwork embedded in ripped FLAC files just does not work no matter what I do. Like I said just in a couple, there must be something in the file makeup the device firmware just does not like. I wish there was a list somewhere of file criteria which is necessary for them to display properly (as in tag version info etc). I am using the recommended 32 gig SanDisk class 10 cards and slot-2 (SD2) definitely has issues if you plug the AK100 into your computer. The units Music folder is fine as is the SD1 slot card but the second SD2 card gets corrupted to the point of having to reformat it and reload the music. The only way I can do it is remove the card before attaching it to the computer. If I follow those rules things work fine, I tried a number of variations but that is the only thing that works. To add, I do not even have to access the SD2 card while it's plugged in for it to get corrupted. Hopefully they will address this in an updated firmware, it does make things very clumsy to add music. The one issue I have that one other person mentioned (that I noticed anyway) many pages back was the hard key 'Next Track/Fast Forward' only pauses it does not go to the next track or fast forward. The other keys work as they should, the top key 'Previous Track/Fast Reverse' works and the middle 'Pause' works fine. I can't imagine that I would be the only one that is having this issue. It has to be a firmware problem. Anyone else? Sorry if it was brought up before, if so I couldn't find anything regarding it. I have even re-did the 2.30 firmware but it still is the same. If knowone else has had this problem then the unit must be defective although I can't see that, the keys are software enabled. I wish that worked as I use it will walking and it would be much easier if it did what is was supposed to. Other than these issues I love the fit, finish and leather case all are top notch. Oh yeah and the sound is pretty decent as well Thanks for listening.
I haven't experienced these issues with my modded mk1. I have had some corrupted card issues, but I don't think it is the AK causing it so much as being sensitive to minor issues.
It does sound like there could be some more serious issues at play for yours, but I'll let others comment before I'd recommend returning it for repair.
