Just right click on your player and create a NEW document (any say "New Microsoft Word Document.doc&quot and just rename it to rkusb.tag and it works just fine.

Btw, here are some typical Rockchip 27xx series players that this firmware extraction method will work on:-

Hello everyone.
Newbie with such player, I have this one above, with 16GB.
Backuping sofware from the hidden disk, there is another file called "HOLDON.BIN".
Anyway, I tried the I PHONE LOOK on it and... It crashed (screen went crazy, irreadable, messy).
I switched it off and never started again.
I had to format the main disk (15,3 gb, and "bye-bye" my mp3 and avi),although the screen stilled dark (I guess it needed the right program to start).
Hopefully, I could reinstall the original files I saved.
Now it seems to work...
Does anyone know what I did wrong ?
The guy on ebay told me it can't be upgradable.
Something else : mine can't play mp4 that I get thanks to keepvid.com.
And yours ?
Thanks for you help !

what did you do, did you just load on another fimrware - you cant do this, your player has yo use its own firmware, if you want a different look then you have to mod your firmware

it wont play MP4 files - convert them im afraid

Thanks for your interest !
I followed this process : http://www.mympxplayer.org/previous-...r=asc&&start=0.
I do confirm there is the same structure of folders, except an extra file called "HOLDON.BIN" in the root of the device...
I thought installing those files was safe, because it's Rockchip firmware: RK27SDK-080422.
Can anyone confirm I can change the look of mine, and how ?
