Hello,
I just get second hand e-book reader with a good screen. I was very happy discovering, that there is possibility to use open source firmware on it.

There is a good news - it is still possible to flash it with KOReader and all the files are here. The bad, the documentation here is not clear for a nooby user.

Devs firmware guide
KOReader install instruction

I do have issues with the first instruction I posted.
1) How do you connect? You remove the cover, find the pads and what next? Is there any standard I should follow while connecting to Arduino? This is easy place to burn something in my experience.
2) The firmware for the Arduino or any other interface that should be used
3) As I understood you start the device and then send a signal ESC? What does it mean?
4) Then console in the device should appear and you input 'init=/bin/bash', then boot. By pressing power button again or other kind of signal?
5) etc

The more I read, the more I lost trust in my electronic and bash skills. The second guide is clear and files are still available in the webarchive. I will backup them and post here.

I believe that leaving this info for any other users still running stock may be good for all, as open source software should be spread. Especially when the producer does not support the device or the registration anymore.

For mods - mother thread is closed, I do not see a way to contact with author in PM either.
