turn on the player, then hold down the center button, connect the charging cable, listen to the music (-;

If you can't upgrade benjie t6 to agptek rocker firmware you should download and install older version firmware agptek rocker and then make upgrade to last version. For upgrade  use combination of buttons on/off  and volume down.

None of the AGPtek firmware (1.01, 1.05b, 1.06b, 1.2) from the AGPtek website works with T6's that shipped with 1.08B (using update.upt through the device).

Unless I am mistaken, only underst0rm has managed to do this successfully by opening up the device, soldering access through serial console, and making a date fix.
Unfortunately, this is not something that regular users (including myself) are likely capable of.
I'd be willing to give it a shot (I do have soldering tools), but would pretty much need a detailed step-by-step guide for what to do.

My fingers are crossed that (sometime in the near future) something will be figured out that will allow flashing from the device.

Not true. In the end, the fix is only to change the version string in the image, not something on the player. No need to open up the device.

Under Linux, I can modify the AGPTEK image to flash on the T6 like this:


--- Code: ---# Download imagearchive and extract image
$ wget http://images.agptek.us/Download/AGPTEK_ROCKER\(20171101\).rar
$ unrar e AGPTEK_ROCKER\(20171101\).rar

# Extract the internal image files into the "iso" folder
xorriso -osirrox on -ecma119_map lowercase -indev ROCKER_update.upt -extract / iso

# Open iso/version.txt, Replace ver=1.0.0.0 with ver=2018-10-07T00:00:00+08:00

# Repack into an update image
xorriso -as mkisofs -volid 'CDROM' --norock -output uROCKER_update_1.8_beta.upt iso
--- End code ---

The same process works also on a rockbox enabled 1.2 firmware. I'm sure you can also use windows, as long as you find something which can unpack and pack an iso image.

shikotee:
Confirmed.

I changed the .upt extension to .iso, and extracted the contents to a folder.
I modified Version.txt as explained by underst0rm.
Using IMGBurn, I rebuilt the iso, and changed the extension back to .upt

I was then able to update my 1.08B FW to AGPtek 1.2.
The interface seems pretty much the same - just more colourful.

Will play around with 1.2 today, and will explore installing Rockbox this week-end.

Many thanks to underst0rm for figuring this out!
