The various Actions Semi SoCs found in most of these shovelware players contains only a couple hundred KB, for example.  Even the higher-end rockchip ones have less than half the RAM for rockbox to be minimally viable.

I got several Actions based players and they are different. They can't even browse files when they are playing music.

This player can. It's like a feature phone without phone. It's not related to actions based players.

Here is a more complete list of fdl files than that it come with uniflash soft: http://chomikuj.pl/hubertus/Serwis+GSM/boxy/GPG+Dragron+3.55/55/GPG+Dragon+v3.50c+Crack+Download+Link+*26+Enjoy+!!/system/spreadtrum

Note: To use those files with UniFlash you must rename correctly and put in fdls folder, because UniFlash take params from the fdl filename, like the memory address to load the file.

Another link to download all those files at once (see system\spreadtrum\ folder in archive):

the uniflash script takes commands for the address and type from the file name by default

ex. sc6600l_generic_0x34000000_single.bin


can be overridden on cmd line
'-sfdl','--single-fdl-file'
'-saddr','--single-fdl-addr'

maybe the address space could be scanned repeatedly and get lucky enough to find the proper offset

I got it!
Thank you very much to Bahus for the rar.

The file that works is 6531A_Write_Full_Flash_1.bin and the load address is 0x34000000

Here is my firmware.

Reading in a hex editor, the firmware contents some info from my device (my bluetooths devices scanned), so it's not "clean" from factory, it's modified with the scans and the current config of the device.
