Hi,
Amazon sell these really cheap and cheerful players - a new V5 version has just been released and I have just taken delivery of a V4 one. I suspect this could be a very capable player but it's let down by really basic firmware.
Out of the box it plays MP3s and MP4s has an FM radio, 4 games, a voice recorder, and can record from the radio. There is a micro SD card slot on the v4 (but not the v5 as far as I can tell)
It lacks any search or playlists though making it a pain to use.
It's apparently based on a Samsung chip (not sure which one).
Windows detects the player as a generic USB drive.
The 'maker' Klastor has no web presence, least I cannot find one, even though the manual mentions that you can download firmware.
Does anyone know how much of a pain it would be to convert Rockbox to work on this? Is anyone familiar with the players/manufacture?
How would I get more info on this players guts? Are there interrogation apps available?
In hope.
J.

Thanks for the replies. Opening the case shows 2 main IC's and a bunch of discrete stuff. Main IC/Nand is marked
Sumsung 204
K9GBG08U0A
SCB0
YBLA80GDN
The data sheet for this states its a 32gb A die nand flash (unless of course it's not made by Samsung....)
The smaller is
AK2117
SC90SBA A7A
This appears to be made by Actions, though I cannot find a data sheet for it at present. The actions website states that its a
'MP3, WMA, FM Radio, Voice Recording, SRS, Picture browse,AMV, AVI(MJPEG), LQFP64(7*7mm), 4wire-card, 24bit ECC flash'
Possibly not very helpful?
There is also a 10 pin IC(?) marked
R1019
S0688
122D
The other side of the board contains the screen and buttons, but no other circuitry that I can see - unless its under ths screen in which case I don't think i'll be able to find it without destroying the device due to the wy the screen and main pscb are connected.
I have 3200dpi scan of the board, small version attached, if this would help with initial identification.
