Firmware Extraction for new Rockchip RK27xx series players.

[ROCKCHIP RK27SDK]

hello all,
I just got my mp4 player yesterday i put about 2000 songs on it and tried to add some lrc files on it and now my player only say I have one song on it like 2000 times with no artist or albums

I also tried removing the song and putting so other songs on there but the same thing keep happening

i need help

i copied the rkusb.tag to the root and i shutted off my player then reconnected it to the pc but i didn't find the invisible partition, also after renaming the file.

My player is Major version ID: 2.2
Hardware ID : 080722

Thnak you

My player looks like the one in the above post. I created files with all known tag-names finally adding a file with name "RKLDSET.FLW" made it. Also I had to rename that file later in order to switch the player back to normal operation.

Cheers

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 !

I have this same problem with the touch screen.What do you mean by hold function? If you mean the LOCK switch on the top of the player,then that's not the problem I have.No matter what firmware (original or otherwise) the touch screen does not respond.Its an RK27 2.2 080722

Thanks

yes, i mean the LOCK switch on the top of the player.
