ADFU mode, not able to load full FW
 

I modified original dump to fix minor radio glitch, but after loading it my 1.5 inch Nano clone MP4 (ATJ2091H, 2GB) the screen is stuck with hourglass. I realised that in modified DUMP, the FWIMAGE.FW is empty.
Atleast it connects with PC in ADFU mode, but while loading original full FW it moves bars upto about 20% & then stays stuck there. I tried many different full FW, no success. I tried shorting memory at differen states of uploading, but all it does is turning off the MP4 & loosing connection with PC.
Ice might be the answer, but making JD-ICE board will be too expensive for fixing $60 player. Is there any other trick?

kunal , there is a post from nickyblast, saying to try various versions of the MP3 Utilities Here. As different versions may or may not work with your player.

The other versions can be downloaded from the downloads section.

Is your firmware version 9.0.48, and if so can u upload it ? Thx

CaptainZap,
I have the dump file that was saved before I killed it. No luck with full FW. Sorry...

I have the same problem as you and we need the full 9.0.48 f/w file to fix it but I cant find it anywhere.

I also have the same problem with a 8gb samsung memory atj2091h player, I can't find the firmware anywhere...disperate =9 if someone can help me please email me rrriki@tin.it. thanks

Re: Recovered!!!!
 

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...

Now I will go back to research on how to fix my radio glitch!
But that will be in a different topic...

kunal,
I am glad you have been able to recover your player with the 9.0.50 firmware, this will give hope to other people with the same problem. Thankyou for taking the time to list the steps you took to recover your player.
Good work :)
