Rockbox on X20???
Does anyone know how likely it is that rockbox will be ported to the X20? I know if it is being planned it won't be ready for a good six months or most likely much longer but is it being considered?

Someone mentioned something about it here.
Your best bet for information is almost certainly the RockBox site though.

Hi, very interesting post !
Unfortunatly, i couldn't find any informations (at least in english ...) on the TeleChip TCC8200 !
As far as i manage to see on google, it seems that this chipset is also used on iRiver Clix2 and Cowon D2, if it's true, that means it's a good quality chipset.
But, is it the audio chipset ?

I would also like to see the x20 rockboxed, however i definitely don't have enough skill to do it on my own. I could probably help if there was a more experienced programmer, but i am stuck on where to start.

Anyone else willing to contribute?

This page at rockbox DocsIndex < Main < TWiki would be a good place to start .

i would also like to know if there is any manual way of upgrading the firmware.. right now the updater automatically downloads the firmware file of the net and installs it. is there anyway by which we can manually install the firmware?

I'm F@#ING HAPPY RIGHT NOW! I managed to extract the firmware from the Insignia Updater v.1.105. With little modification and rehasing i managed to flash my X20. I think this is an important step. Here are some photos with the X20 with Insignia firmware.

That's quite impressive, well done ! I'm not familiar with the Insignia player, what does it have in common with the X20 ? Does the Insignia firmware have any working features that the X20 firmware does not ? I presume the bluetooth connectivity does not work !

the insignia NS-DV8G and the x20 are very similar. i've read that the x20 is a rebranded insignia or vice versa. anyway, the most important part is that they have the same brains (telechips tcc8200) and mp3 decoder (texas instruments TI TLV320AIC23B). the bad part is that there is no sound with the insignia firmware. more details here. check the rockbox forums as i'll post there if i succeed in anything. I've seen some new features on insignia, such as audiobooks (i guess it may have text support, but didn't test it) and some useful settings such as turning off the lcd completely while listening to music. now, i reflashed my x20 back to iriver 1.07

for reference go here. firstly, i downloaded the insignia firmware and used a hex editor to extract the raw file from the exe. it starts the same way as the x20 fw. read the size from the header (see the ref) and extract the firmware. then delete the last part of it so the end of the file will look like the x20's fw. then use the code here to write the two crcs and the filesize so that the x20 will accept it. NOTE: 1. Using th insignia fw you will have no sound! 2. You will have to use a procedure similar to the one described above to install the original x20 firmware, but you will have to make it look like insignia fw. 3. Be very careful! I tried to install another firmware using the same method and "bricked" my x20. It doesn't start now.

I'm NOT responsible for any damage resulted from using the method above.
