Yes!
I did it!!
Steps of recovery from hourglass stuck nano clone:
Step 1: download full FW 9.0.50 from
http://www.mympxplayer.org/full-vers...lcd-df430.html
Step 2: upload 9050 to dead player. This makes my player have a blue blank screen with a dark line at bottom of screen.
Step 3: disconnect the player & restart using on-off switch on top of nano clone. Then reconnect & wait for few seconds -now player is recognised by PC as removable disk. (If you turn on "MP3 Player product tool 4.19", it will recognise mp3 player with removable disk).
Step 4: Now upload original dump bin.
...That's it back in business. Now I am back to my original settings.
Here is my player's specs:
2GB Nano clone with brand name "Kudez"
CPU: ATJ2091H
Good luck to all...
