For now I put some info about the TV connect here. We can later make separate wiki entries for it.

How to boot into recovery on Archos TV connect

• Pull the powercord.
• Press the powerbutton and insert the power cord.
• Let go of the powerbutton and press it shortly once more.
• Now there should appear a white screen with the LUDO recovery on top.

NOTE:

• to navigate through the recovery menu you need a USB keyboard. Use the up and down arrows to highlight an entry. Return or enter with select that menu item.
• to enable SDE you need to install SDE gen10 which currently only list the "ARCHOS 101 XS" but also works for the TV connect. You will loose the ability to play DRM content.

All is now handled in gadget android which is build in the original kernel, so no separate modules anymore. Functions can be changed by writing to the sysfs.
Below is an example on how to get a console and kernel messages. Add it to your init script.
