Philips GoGear SA52xx

I think this device deserves rockbox on  it.

its got alot of potential, seeing as ithas a nice LCD screen, can play video, radio, bluetooth, Rhapsody, Music, and much more, but it also is very limited in its sound features. but if rockbox is ported to it (if it is ever considered) i feel that the "fullSound" Feature, should be kept, simply because it is AMAZING in quality. but yeah... lets get this ported, ya?

UPDATE:
found the firmware files, the player file, and a helpful info file that can be modified to direct the bios to load up a different player/firmware, such as rockbox. as soon as i get the files uploaded, i will find someone interested that can help, as i am not very good with decrypting anything or messing with those kinds of files.

What device doesn't?

How would we "keep" something? Rockbox is not a modification of the existing firmware.  It is a complete replacement firmware that must be ported to the device and as such, we would have to implement whatever "fullsound" is into Rockbox.

Full Sound is Philips version of blueray's Video upscaling, but instead is an audio upscaler.

which makes your music sound "decrapified."
im working on finding a way to let it show me the firmware, because it isnt in any of the hidden folders, and there are no system files. just empty folders (which might be a .tar archive since it has doen that to me before EX: transfered a .gz or .tar linux file to my xbox, and it turned into an empty folder.)
so im still messing with the device to try and find the firmware and get it into an mi4 file if not done already by the manufacturers.

So I want to do some work on this one. I got the SA5285. Already read some wikis and stuff. I want to open it and scan the pcb but I don't know how to open the player without breaking it. I looked at it, I can lift the back up a bit but only on one side. and I don't want to use blunt force and break something. I looked on the internet and didn't find anything. then I saw the wiki page for the 9200 on here and it looks a bit similar to mine. maybe I can open it the same way that the person did who opened the 9200.
Anyone got any tips on how to open it safely? of course it's my responsibility...
thanks.

i got an 5285 (without bluetooth). You can open it with a little screwdriver in the hole at the right botton. ive done it, but you cant see much. sorry for my english.

[rottenzombie]

yeah I opened the case a bit at the top. trying to remove the back but when I tried to pull it apart it sounded like it was glued together and stuff so I didn't go further. I really don't want to break it.

[Laci]

it is glued in the bottom, but you can easily remove the cover and the glue will stay there.

PS: you can go into a production test mode. shut down the device, hold vol up and vol down and power it on.

[rottenzombie]

I'll try again tomorrow.
thanks man production test mode is cool...do you know any more things like that?

[Laci]

yes. turn it off, hold the menu key (the one with the turning arrow) and power the device on. now it is in a direct usb drive mode, not the strange default mode.

[rottenzombie]

thanks for your tips laci.
guys this is how far I am right now(couldn't scan so I made a pic but it's good enough):

do I need to open it further and get pics of the whole thing or is this enough? If I have to I'll do it...

some info about the cpu here:

I couldn't find anything about the other components yet, I'll probably have to remove that white sticker too right?

I've never done anything like this but I want to learn how to do it. I'm willing to read a lot too, just need some little help to get started.

Bottom right is an SDRAM chip, left side is a NAND flash memory chip. 

You should create a wiki page with this info on it.

[rottenzombie]

thanks saratoga. I did that:

anything more to add right now? I linked the page in the pre-development section. I'll try to open the player a bit more and get more data.

Try and figure out how firmware updates work.   Theres a lot of TCC chips that already have rockbox ports.  Maybe one of them has already figured out how to update the firmware to hacked binary on your player?  If not, try and figure out whats different about this one.

I dont know if this helps but on the Go Gear Vibe /17.Firmware updates work with the Device manager and if you go to were the app installed there should be all the files of the FW in the firmware folder at least with the Vibe /17 I have not tried this but you can tell the device manager to not check for updates and then if you click update I think it pulls the files from that folder and puts them on the device maybe.It seems to work for my player
