Hi, I have a Defy and I am running MIUI 2.4.13 on it. I was trying to modify certain part of the V4 lockscreen and after i was done when i tried to import this modified lockscreen to the themes it simply wont show up anywhere. Here are the steps that i followed to do the required changes: 1. Renamed (changed extension) of the lockscreen file from .mtz to .zip 2. Extracted the contents to a folder. 3. Renamed the lockscreen file to lockscreen.zip 4. Extracted the contents of lockscreen file to a folder (folders name was lockscreen) 5. Deleted the lockscreen.zip file 6. Changed the images as required with appropriate ones (images were exactly the same except for the color of images) 7. Compressed the contents of lockscreen folder to a zip file and renamed it to "lockscreen" 8. Again compressed the contents of the parent folder to a file and renamed it to "xxxxxxx.mtz" And then finally when i tried to use this file, nothing showed up in the themes area. I dont see my lockscreen over there. I tried doing the above using winzip, winrar and even 7zip. Nothing works. I just want to know whats going wrong. Thank you.
