Firmware Extraction for new Rockchip RK27xx series players.

[travis90]

ATTENTION!!!

Here the solution at the problem of the two devices!!!
If we copy the file rkusb.tag into the root, restart and connect it to PC, we can see 2 devices,
but if you delete the file rkusb.tag, at the next restart the second devices (the hidden partition of the system files) doesn't disappear!...
This happens because we must replace some system file before deleting rkusb.tag!!!

Go to /Resource/BID of the hidden partition
I tried to copy BMP0.BIN on my PC, then I've deleted BMP0.BIN in the folder, then I've modified BMP0.BIN (changing some images with RK27UIEditor2) and recopied this BMP0.BIN from the PC to the folder of the hidden partition.
Then I've deleted the file rkusb.tag, disconnected the MP5, so a red screen appears, because it's changed some images, and finally I've restarted the MP5 ...
So with the next connections the hidden partition disappear!!!

OT:
I've uploaded this firmware at the link of the first post, but I don't find it...
The name is
Rockchip firmware: RK27SDK-080422-1.2 I-Phone Style
http://www.megaupload.com/it/?d=KR6U30SG

How I should do?

hi travis90

thanks, the admin will make the download active, we just need to wait a bit.

Thanks for tip to close the firmware partition! :-)

[travis90]

Oh, don't worry!! Thank YOU (to all the forum) for yours helpfulness!!!
For the download... I didn't know that I had to wait a bit... '^_^ sorry!...

However... putting the solution of the 2 devices at the end of the guide in the first post isn't a bad idea... no?

If this doesn't happens, you tried to modify the file BMP0.BIN changing some image before the "recopying" onto device!

DOES NOT WORK!!!!!!

[travis90]

Dingchow, have you tried to modify the file BMP0.BIN before replacing in the hidden device???
Because if you delete the file rkusb.tag, and then replace the modified file BMP0.BIN, at the disconnection and the updating of the library (before the restarting), you should see a red screen!!!
If you don't see this, you haven't correctly done the procedure...

[travis90]

I've rewrite better the procedure...

It was kinda hard to understand. I did not edit the BMPO.BIN file and did not see red screen. I cant find RK27UIEditor2 to download it. You have a link for it?

[travis90]

You can find it here
http://www.mympxplayer.org/rockchip-...7xx-df896.html

I prefer to use Imagesearcher, but I don't find it in the section of the download...
So I've upload it here
