Hi,

first. thank so much from your suggestion...(Riolist,knob,DaremoS,...)
i have same problem (paul01609, dnul and ...)..flash wrong firmware.
...touchscreen and buttons not working...
i try from your suggestion
"knob"
1) Switch the player OFF using the main on/off switch.

2) Hold down the menu key and keep it held down.(may be a different key for you but there are only 5 to try anyway)

3) Connect the usb to the player.

4) Wait for about 10 seconds before releasing the menu key.

5) You are now in upgrade mode!

6) Then just start ConsumerUpdate and upload a working firmware

and "Riolist" i try step by step ...my computer can see USB Mass storage device. (1.RockChip Usb mp3 usb device.. Generic volume E: 2.RockChip Usb SD USB device.. Generic volume F
but touchscreen and buttons not working too..show as pics..(i understand u "paul01609" )

You are not in the correct mode. Those are the data partitions, you need to get into the upgrade partition, which is hidden and can only be accessed either 1) with the player 'OFF', holding a button down then plugging in to computer, or if that doesn't work 2) shorting pins on the memory chip inside the player, as Paul did. In addition, once the computer is connected to the upgrade partition you have to load the correct driver, which is in the install folder of the upgrade program on the computer, then you'll be able to flash the correct firmware. Read and re-read the other thread, all the information is there.

i tired all ways to try get my pc to see the device as a rockusb with no luck and spent about 12hrs trying to sort it.in the end i opend the back and used the shorting pins trick on the chip which in total took me about 3mins inc opening,at the end of the day i had a almost dead player so i had nothing to looose but it worked

ok i opend up my player again and taken some photo of the inside,just get a very thin screw driver to prize open the back of the player(you prolly will leave some marks on the plastic)then carfuly remove the battery but go steady as the battery it glued down,then leave the player tuened on and connect it to your pc with the usb,on my chip i have a large v shape looks live a pen mark at the bottom of the v and to the left of it thats where i made the connections with twizers,if you join me on msn i have a picture of the chip and area i did the connections on,i carnt say which ones i connected because i carnt remember it was more look on my behalf,msn is paul01609@hotmail.com

the correct way to make your computer connect is:
short circuit the flash's 29 and 30 pin. hold it and connect the USB cable. after hearing connect sound from ur PC, release the short circuit.

hi, paul01609 how about your player(onda vx858le) .i opened up my player and i don't know how to short circuit legsROCKCHIP RK2608A from interuptor0,Riolist ,knob,DaremoS supported. my chip(ROCKCHIP RK2608A) like this

There is more information on recovering this type of player here:-
http://www.mympxplayer.org/2-vt7807.html?postdays=0&postorder=asc&&start=15

Please make sure you only try to flash the CORRECT firmware.
VX858 and VX858LE are 2 different players and their firmwares are NOT the same!
The VX858 uses a separate audio chip, VX858LE doesn't.

Here is a photo showing which 2 pins you need to short (29 and 30).



Hope this works for you...

hi, knob
you meaning shot pin 29,30 rockchip rk2608a or sumsung 725(flash memory) .thanks you for your support.

NO, Not the Rockchip try the flash that's the same shape like the one in the picture above, might say "Hynix" or "Samsung" on it or another brand on it, must have the same shape as the chip in the picture.

Thank you to all for your kind support . Now i recover my ONDA VX858LE already...Here is datasheet sumsung 725 (K9LAG08U0M) for short pins 29,30 http://www.touchdev.net/wiki/Image:K9LAG08U0M_0.7.pdf .
you can do by "knob" guide at http://www.mympxplayer.org/rockchip-dead-player-recovery-guide-vt6686.html?highlight=dead+rockchip

Thank you very much again.

i hope usefullness...

I did the short circuit method too in my Onda VX858 emulator and it work fine as usual.
The only problem was that I spoiled a bit back cover... anyway I enjoy playing with my player not looking the nice manufacture

What I found inside was all of unknown manufacture... the only know chips beside Rockchip, were Samsung, a couple of them (flash and bios keeper) it took me some time to discover which Samsung I had to short circuit.

It get locked because I install VX858LE just to know if it can work... Geez... finally my player is VX858 V1 as V2 firmware works pretty bad in my device.

Recently I learned to play with my VX858 when is charging the battery via USB port.... anybody knows how this is called?. I mean to have the player USB plugged while the user is playing music or whatever.

How did you do it DaremoS???!!!!!!

What do you mean buy V1 and V2 firmwares, are they different? Does an VX858LE have V1 of 858LE and V2 of 858LE??? Please HElp!!! MY PLAYER'S DEAD!!! (works fine, touchscreen is non responsive)
