 The firmware though on this device is primative in that in order to sort anything you had to use a program to reorganize the device since it sorts files by when you put them on the device so if you put an S folder before C it was like that until you used an external program that changes the attributes on the folders/files by file name by changing their transfer time. CEC didn't supply this program of course.  Stopping a song sent the device to the main window instead of stopping at the folder where you were playing. Mp4 playback was always out of synch. Photo viewing painfully slow.

BTW, the OS is made by Telechips and Telechips refuse to provide any source code for us to work on. Hence, there is nothing much we can do about the OS unless some RockBox developer can help reverse engineer the mp4 player to make Rockbox work on it. (In short, we should be able to find any info you need except the telechips source code)

This was not the case...at least with the two hi-x6 that I owned. The only way I could get them to play in synch was to convert them 1/2 the size resolution at 15 frames and audio at 48k. Basically something that the Zvue players were  using worked.  However this is moot.

I was told by CEC several times that at first that the processor wasn't strong enough to arrange files in alphabetical order...this is not the case.

Anyway I didn't like the firmware and confirmation that rockbox couldn't be ported due to the processor specs not being available I gave it away. However my brother doesn't like this player either and bought something  else. I'll see if I can get that one if someone from the rockbox team wants to look at it.

Try the software on my site (the old one), I have tested it on X6 and I am sure the picture and sound are in syn at 280x220 15fps. (if not, maybe a firmware upgrade will fix it)

Look at my site's FAQ, there is a "fix" you can use to sort the folders. The way the player sort the folders is by the date you put in the files. Nothing to do with processor, just the OS.

For your information or anyone else's interest.

There is at least one Rockbox developer trying to reverse engineer the X8 firmware.

However, do not expect Rockbox to work on it anytime soon because we have no idea how long it might take or if the reverse engineering will be successful or whether Rockbox developer working on it might decide not to work on it.................

(If you want it faster, come and help work on it as a Rockbox developer)

Yes I know all of this I spoke with you many times on CEC's forum and emails.

Well maybe those cute animations cec puts on the players will play at that rate, I was using music videos/movies.

I told you about the software that will alphabetize the files since everyone from CEC said to "defrag" it :-p

Cheers if Hi-x8 gets ported I will order one from you the next day if I see progress.

I will then order one and start learning to contribute, at present I'm not capable of doing it from scratch myself.

First of all, thanks for that trick.

I believe by the time Rockbox works on X8, we might have other new models you might want to consider. (No concrete plan on new hdd based m4 yet.......at the moment.)

To aid/encourage efforts to reverse engineer this mp4 player, here are photos of the opened X8.
(Higher resolution photos available from me.)

Bagder should have made X8 PCB diagrams and OTG datasheets available to Rockbox developers. Or request it from me.

So far, I am not aware of any significant progress on this port.


X8 with its front cover opened.


X8 with its front cover and LCD flipped


X8 with its LCD removed. Note that the connector next to the battery is used to connect to the keypad on the front of the X8.


X8 with its battery flipped


X8 with its back cover opened. This is where the hard disk is installed.
