Hey guys. Sid, you have the same player as knob has. Do you also have audio problem? (mono signal on headphones). I am interested in buying 27XX player but I want to expand the firmware (RTF reader and subtitles on videos). But if something major (like audio) is bugged then it's pointless.

Has anyone a working player with compiled SDK, without any problems? If so, please give me link to some shop or something.

So I used your post here : Rockchip DEAD Player Recovery Guide

The hardware tweezers method makes sense to me.

The idea is to short some data lines together of the MLC NAND Flash so the RK270x ROM CODE will always read wrong data from the flash and will never find a valid bootloader. Then, it goes into this RockUSB mode automatically to give a chance to reprogram the whole flash.

This is very cool !!!! ( although i would prefer the soft mode haha )

I never had to open this player yet!

sid6581 I hope you carried out this procedure in case your firmware is different!
Firmware Extraction for new Rockchip RK27xx series players.

This repair tool will get you into rockusb mode:-

The space on the pcb might be for the wolfson audio chip.
the red screen usually indicates something wrong with the BMP0.bin file or it's missing, strange.
Does the player operate blind?, can you navigate and play music?

Unfortunately, I'm not very experienced with c or assembler. So, I'm just putting the idea out there.

Yes I fully agree. It's crying out for a tool to extract the screen, button and audio settings to apply to the firmware build. In fact I think it's a must if we are to get maximum users involved.

for screen issues we could create some wizard in which all the known lcd drivers are loaded one by one, e.x. in every 15 seconds. And if screen works, you would hit any button to set current driver. This way we wouldn't need to compile everything to make it run on other players. The wizard would be initialized at first run only.

Ahem no I haven't :-/

But it does not matter too much if i never go back to my original firmware.
My goal is really to upload my own recompiled firmware anyways, but so far it is red :-P

Thanks, could you point me on the tool I should use to upgrade this firmware ?

Also, I have seen online that there are firmwares that come as a big .rkw file (like 30MB ?)
While yours come as a directory structure.
What is the difference between those two ways, is the big .rkw just a packed version ?

I was able to use the repair tool and just put the ramos970 firmware in it and it works.
It's funny now the audio has this problem of not having the voice (left channel and right channel are substracted from each other), so that's something to do with the firmware and it will be correctable.

just put a file called rkusb.tag on the main drive then reboot and the firmware partition will open up, then just copy the 4 folders across and reboot - no need to flash with RK27xx rockchips

You can upgrade with .rkw using the Repair Tool if your brick your player, just rename the file to SETUP.RKW and put it in the firmware folder below the tool.

Hi Knob,

I used rkusb.tag and saw the hidden partition.
I then copied the files from our original firmware : Download Rockchip Firmware: Rk2706 Player from Tinydeal - MyMPx

The player still goes RED

The player I bought from tinydeal is exactly the one you have (btw it is a RK2705 inside, not a RK2706).

I have no clue what i am doing wrong.

When the screen is RED, two drives still show up.
One is empty and has 60MB free
One is full with the hidden partition stuff but there are no files in SYSTEM and no files in SYSTEM00 directories !
