Then I did the update and it updated without problem.
The 2 first time boot, I got a message that Rockbox cannot boot. And the third time it worked.
So far it seems to work, except that I cannot use the power button to switch if off. It seems that the power button is behaving like a "Go Back" button.
So I have to hold it down to force shutdown.
Perhaps it is the way Rockbox is behaving ? Anyway I will then go over another topic to ask about Rockbox behavior.

I'm not sure how to edit the behavior of the power button, for me it unlocks/locks the buttons and yes if you press and hold the power button that's how it shuts off on mine as well.

I am even not sure it doesn't accept only Agptek updates or updates in general (Did Benjie ever published update image for T6?). Gaining access to serial console is pretty simple (soldering 3 wires to test points + 3.3V usb-to-serial converter) if they didn't removed support for this. From there it is pretty easy to extract recovery firmware. I can help if someone with 'faulty' T6 is willing to take the risk.

I have opened up my unupgradable T6 and got RS232 access.
Notes:
* Hardware is labeld K1-V4.0 2016-12-13. So hardware probablz did not change
* When flashing an older File, the recovery code complains with version too old:1.0.0.0. See https://pastebin.com/ZjrAHZXY
* The complaint only goes away when changing the version in the iso file to 2.0.0.0
* When changing the Rocker 1.2 firmware to this new format. The bootloader sas an additional compile:2018, 6, 30, version:2, 10, -2146731964. However on the screen it still complains with v_v failed . See https://pastebin.com/VyeD38Ks
* Layout of mdts did not change, see https://pastebin.com/cR3ka6Y5
* Standard boot looks like this https://pastebin.com/BnE6Vxbm
I did not get ADB over USB to work to get the recovery mdt and analyze what else it needs to be happy.
underst0rm:
Silly me... Why do I have sdcard in that system to copy data onto ;D Hint's on how to get ADB working would be helpful still though.
Anyways. I now have the whole set of mtd devices mirrored on SD card. I'll try to extract the recovery image and see where to go from there.
EDIT: I got so far as to getting the decompressed Image of the recovery file.
dd if=mtdblock3 of=Image.gz bs=64 skip=1
gunzip Image.gz
However I do not know how to get the initramfs from this..
EDIT2: I got to the initramfs by using binwalk. However, it looks like the actual bootloader (recoveryd, initated by /etc/init.d/S90user)is a binary file..
EDIT3: Got it! The version format changed from a simple version code to a date, as shown here: https://www.rockbox.org/wiki/ShanlingM2sPort
That's also why it did show a date when changing to version 2. - the year starts with 2 also :-D. Putting in todays date updates the player. I'm no being shown a chinese USB info. Will put it back together but I believe I'm on the rocker firmware 1.2 now:
--- Code: ---(GUI:D)lg_activity_usb: on_create
Device setup complete
Name: HibyPlayer-888888 -> AGPTEK ROCKER
Agent registered
--- End code ---
EDIT4: Applying the date fix to a rockbox enabled 1.2 AGTPEK image gave me working rockbox and a better AGTEK firmware. I do not believe these changes to be malicious. They just updated their kernels and bootloader. Unfortunately, this breaks firmware images since the boot loaders are not compatible anymore. But hey, we got it working again :-)

Joe Average here! I just bought the Rocker and am pretty happy with the original software.
However, I miss Rockbox (from the Cowon X5 and Sansa Clip+ days). I browsed the forums with regard to the Rocker but am still not 100% sure:
- Does Rockbox work on the Rocker already?
- Can Joe Average install it already? I'm not a developer but can usually follow power user instructions.
- My device came with firmware ver 1.2. Is that a problem (how do I tell if my device is upgradeable)?
Any help or pointers would be appreciated!

1) Yes rockbox works on Agptek Rocker
2) That depends. If your device is 'upgradable' (and so far only Benjie T6 appears to change update process) you can follow instructions in this thread and use prebuild update images linked there. Main binary can be taken from http://build.rockbox.org/data/rockbox-agptekrocker.zip
3) So far the only way to know is to try updating. If device refuses to update you have infamous unupgradeable device. The issue with this seems to be sorted out but none prepared ready to use images so far.
