I bought the device from ebay. Device to create a new folder outside of the standard folders that I copied into the folder of image files. After the file has been corrupted files, I noticed when I want to watch. The other half of the image is properly part of the picture was distorted. Turned to a very strange character filenames. File names changed automatically on the device itself. I think I turned off the device improves. That did not work then the device again. I want to run the device at the screen I see the WELCOME text. I reset a few times. But the problem was not solved. I think I delete the files from the device installed in such devices will not work. Computers do not perceive it. So I can not connect to the device with the computer. How can I solve this problem? Many thanks in advance for your help.
