First, sorry for write in english. I am using google translating to read the forum content.
DEFAULTx i have a mp3 player like one you posted, mine includes micro sd reader with support up to 8 GB.
I did the mistake of overwrite the original firmware before backup it, i was trying fix the fake memory/flash problem. This is a problem of memory size, my device recognize 4GB, but the samsumg memory chip (K9F4G08U0M) has only 512M bytes.
I spent a lot of hours to find the correct firmware to recognize the micro SD unsuccessfully so far. I tested the micro SD with the original firmware, and it works, I was capable of access the folder in the windows explorer. So, it isn't a hardware problem, remains a software/firmware problem.
I found some firmwares that work only with the internal memory, the sd card was not recognized.
If your device does not have micro sd or you don't mind about it does not work. You could try the following firmwares:
3188C-5KEY-WEBSONG-2011-TDA8309Cbig lcd
3188 128-64
M55 3188C
It seems to whatever firmware with "3188C" detail worked with me. I used the tool fusblink28_FAT32_20110517.exe (BR3188\BR-3188 FirmwareModifyTool7028).
All these files are in the compacted file provided by avalon: http://mp4file.ucoz.ru/forum/21-60-2&usg=ALkJrhhUDS9kdvZlbfQfH-rDHBlF9QxLPg
By the way, thanks avalon.
My device details:
Board: KW8520 V:2
Chipset: BR3188 PAWG8-010
Memory chip: Samsumg K9F4G08U0M

Hey guys, I found a compatible firmware to SD card here: bbs.mydigit.cn/read.php?tid=281174&fpage=24
The file is: 新版3188C_12864_Nand 带TF卡带FM=5807.rar
Use a translator and good luck.
I did a few tests, a micro sd card (2GB) was read by the MP3 player. However, when i connect the MP3 player to PC, the windows explorer could not open the sd card, complained that the sd card was not formatted. I don't know if it's a problem of kind of partition like FAT16, FAT32 or the firmware is not the perfect one to this mp3 model.
Need to conduct more tests to improve stability, anyway the most important is the fact that the MP3 can read the SD card now. The function autosearch FM does not work properly, you need to manually tune. I think it's a bug of the firmware, because the firmware WEBSONG autosearch worked. The function of playing mp3 works correctly.
