ViDrop only worked once... and now never again?
 

I have a 16 GB "MP4 Player" Touchscreen With Camera from china. It has the Rockchip.

I've successfully used Vidrop... but only twice. For some reason it won't work anymore. The video played once, and then I deleted it from the player (but it was still on my hard drive). I then put the exact same video back on.. and I get the format error.

Any advice? I tried reconverting.

Did you ever unhack the memory? False capacity controller chips can cause a wide list of various unexplained errors and glitches.
