My MP4 was not dead, but doesn't work
 

I have a MP4 with Chipset Samsung it used to be dead but a friend had another one, we bought it together, i follow the dead recovery guide and it is alive again, but when i extract the firmware of the mp4 of my friend it said that have a problem, doesn't recognize some files, instead, i import the dump file and now the sand clock appeared but then when the programs should show, a white light is the only thing it display. Help me, if you know how can i extract all the dump file, or if i can fix it.

1. Upload that dump on the site for us pls...

3. Try to format your player...

4. Try another dump...
