[SOLVED] HELP find hidden partition RockChip RK2706

[mac_gyver]

Hello

I have a problem with my MP5 player, this model:
It has a RockChip RK2706 and 16Gb memory.

It suddenly died and showed only black screen
Unfortunately I hadn't done any firmware backup.
I was able to find the hidden partition by using
"RK27DM.exe" and "Rockchip RK27 Upgrade v2.5. RK27xx flash tool"

I put these firmware files on that partition:
http://www.s1fw.com/RK2706-Firmware/...FGD240FLW.html

They seems to be wrong, now the player only shows white screen.
I'm able to only access the main partition (16Gb)

I think I have found the correct firmware files now,

The problem is that i'm not able to find the hidden partition any more.

I have tried the same method as I used before, but "RK27DM.exe" only give me an error message.

I have also tried to put "rkusb.tag" on the main partition but without luck.

I'm stuck

Someone plese help me, what can I do to find the hidden partition ? to upload the correct firmware files ?

Try this procedure:-

You must see the Rockusb icon, the player has to be in Rockusb mode for the upgrade to work..

[mac_gyver]

I'm not able to get it in RockUSB Mode any more.
First time I tried it succeed, then I uploaded wrong firmware to the 60Mb partition.
And now when I try RK27DM.exe I get this error message:



What to do now ? :roll:
Is there any hardware reset or something I can do ?


By the way Happy New Year Everyone!

I'm sorry I'm a little bit late.

But here is my guide how I did to hardware recover my player:

Hope it help you.

If you have any questions, feel free to ask me.

thanks for the guide but for all those that can still see the hardware partiton try this before opening the player, its a way to get to the hidden partiton without opening it

now with your player mac_gyver, i have the same one and it loses the firmware partition randomly , what i do now is in the rkupdate tool folder you will see a small file called setup.rkw, i have now copied this to the root of the main memory of the player, now when the player dies (as it does often) i plug the player in and it instantly gets recognized now and windows sees the hidden partition but its dead and it asks me to format it, i do and the partition is then alive for me to copy back up files on, also i have the rkusb,tag ffile on the player also

this no means i can be up and running in no time at all if the firmware dies again (and again), take alll of 2 mins

so, copy that little file over to the player and leave it there, it wont mess with things, only when the player partiton is dead

cheers

Ok, thank you for the tip makd511.
My player has only died two times.

But I will try your method it looks easy
