[Asus Transformer TF700] Arsenick:
First of all thanks a lot for your contribution! I tough that device was good for the trash and now I have hope! I have a TF201, I'm not sure if I did unlock it back then so I'm trying to do it again but faced the same problem as you and found your post, woohoo!

Followed your step, got the right DMClient for the TF201, got the UnluckV7 included in the same zip as the original DMClient you made, there's no differences in the unlockV7 for different devices right ? Had to root with motochopper tho, but everything worked as you said except I never saw the "optimizing app" after copying DMClient.apk and your unlockV7 and the reboot, correct permissions, no error in the log, the unlock app install correctly but when I run it and try to unlock I get the "unknown error occur" using logcat I can see an SSL error, to me it looks like TLS v1.2 is not supported on my tablet so the DMClient is unable to reach the DMServer which have probably disabled old ssl version for security reason.. The url work when I do it on my desktop.. Any idea on how to fix this ?

I did a few restore to the latest build I've found on the asus support page so I run WW_epad-10.4.2.18-20121122. did the complet procedure few times just to be sure I haven't miss anything but I can't get it to work.. I'm out of Idea, anyone here want to throw any idea so I can try to fix it and install katkiss ? :p

Thanks again for your work, these initiative keep this community alive!

Here's the relevant part of my log when I try to unlock:
