  I'm having problems with uninstalling the Sound Unlocked Rockbox. I put the image file of stock Mango 1.6 in the root of the card, recovery mode and install from SD came up with no update or faulty update. Have tried different cards, downloading the image file again, factory reset from recovery.
Factory reset wiped the ".rockbox" file and left the player in iBasso audio start up screen, adding the RB file allows the player to boot into RB, but I can't seem to install any other firmware.

 
I also have a problem with the install (I touched where I should not). And I had the same problem trying to install 1.6 but it was without problem with 1.5, after I installed 1.6.

Did I get this right, you were able to install 1.5? I will give that a go.

Yes.

Still comes up as can not find update image. I placed it in the root of the sd card, boot into recovery and update from sd card.

So if someone give you something and said it's improved do you just believe it and not verify if the claim is correct?

Ok, you repeated another claim like a mantra

Like I said rockbox directly access the DAC natively not by Android platform.

Just be consistent and please point to this part of rockbox code where rockbox directly access the DAC. (maybe rockchip aSoC layer is wider? where were implemented such things like `fir_rolloff_speed`/`irr_bandwidth`/etc?)
 
 

   
I'm interested in what this modification is that makes what you call hi-fi sound.

No more any mystic. It was an abracadabra not a hi-fi sound, sorry

I repeated this on my device using 1.6.0 FW. Seems like 1.2.2 `updater` bug try to re-run "apply update from SD card" several times.. works for me.

BTW, I wanna share some information to rb developers I found recently. I think it would be helpful.
 
here is Mango 1.5.0 source code - https://github.com/liuwenlong/my-linux-gui
 
Pretty sure it can be used to fix some issues, like battery level, https://github.com/liuwenlong/my-linux-gui/blob/work/apps/player/playingView.cpp#L598-L612 or improve usb dac implemenration/etc

Look here, Rockbox directly access the kernel level ALSA drivers not the Android Audio stack. Although the code branch is under the Android sub-branch, the DX50 port do not have dependency on Android's stack.
 
http://git.rockbox.org/?p=rockbox.git;a=tree;f=firmware/target/hosted/android/dx50;hb=HEAD
 
That is why I am asking where you exactly added your enhancement that affects Rockbox.

that's it, no any direct access the DAC/etc, just some implementation for PCM interface of platform driver(using tinyalsa or whatever). So read my comments above I'm talked about rk2928 platform in general, I didn't change any line of code in rockbox, it was  ArgelErx's & cholero version. Just added some abracadabra, sorry for using "hi-fi"/etc. 
 
Cheers!

No worries, I thought you made a fix or mod at the ALSA drivers that is why I'm curious. Funny thing is people may have already believed "Rockbox" sound has improved.

Thats just the source code for the dx50 music player app, which is what rockbox would replace.

Interesting, thanks!

But you still did not give us the recipe of your abracadabra. You don't have to, but it would be nice.

I tried running it 10-20 times with both 1.5 and 1.6 but still no joy, "can not found firmware image or invalid image, update aborted".

Yep, no worries, I thought a rockbox directly access the DAC is why I'm curious. But no luck.

As I said above.. It would be helpful for someone.

sorry for this( try  RKbatchtool

I already tried the RKBatchtool as well, but as I have windows 8.1 it doesn't recognize the DX50 when it's switched off, or at least I can't find a version that does. Trying to install the RK USB drivers manually will not work either. Does the iBasso RKBT work on win 8.1? The link seems dead and I can't find it anywhere on the iBasso site either.

I haven't used mine for long, so i might be confused a bit,
 
but seeing you have dual boot, then i guess you have cwm, i think that won't update original stock image update.img ? i think you have to be on stock recovery to do this ?
