I recently purchased an mp4/mp5 player from chinavasion, however it has since been taken down from their site. From checking the firmware which was supplied on the cd and from looking at the processor, i am guessing it is a varient of the Jren JR-866
The specs from the old chinavasion listing were:
Memory: 1GB, 2GB, 4GB, SD Card (Max 2GB)
Display: 3.0 Inch LTPS TFT
Movie formats: MPEG 4 AVI, MPEG1 standard DAT, MPEG2 standard VOB, MPG, Real Player3, RM, RMVB, FLV
Music Format: MP3, WMA, FLAC, APE
FM radio: 87.5~108.0MHz
Dimension: 60×97x12mm (LxWxD)
Manufacturer Ref.: U5MCX6PF6LGY
images of my player from chinavasion:
The player is generally good, although it tends to struggle with ensuring video and sound are in synch on some video files.
The firmware is 9.5.5 and is easy to update with the mguires firmware. I was also able to load and run the Gemei x750 (9.3.5) firmware although it seemed to mess up the colours.
The main issue with the player is it frequently has an error after about 15 mins of use (video or ebook) and appears to stick on the 'up' button. this generally requires a reset to solve it. Probablt the reason it no longer appears on the chinavasion website!
Any help, links to more up-to-date firmware etc. much appreciated. I shall also aim to upload my firmware somewhere incase it can help others.
