OK, nothing happen.

So, restart all :
- remove batterie
- "holding in the small hole near the bottom and pushing in a USB cable" connected to my computer
- fast check with "rkflashtool p" to be sure that the computer detects the mars likebook
- running the "upgrade_tool" non-free software provided by rockship

Loading firmware...

Upgrade firmware ok.
root@my.computer:/tmp/Linux_Upgrade_Tool_v1.21#
then, the device reboot
- fast white screen
- fast old image about "likebook starting up..."
- black screen
- ~30 seconds of a black screen with a white border circle in the center with "ereasing" under the circle (not in the center of the circle like I said before)
- black screen
- nothing happen



Did I miss something?

A car battery can show 12v but not have enough juice (amps) to get things going. Saying that I've no idea how the different technology of these batteries holds up in an e-reader. All batteries fail sooner or later. The Mars is a few years old so you can't rule it out.
indeed, it's a 4.35 V battery (3100 mAh), maybe it was a bit low at my first try 4 days ago.
So just to be sure that it is fully charged, I plug it in a charger and the black screen turned into a white one with a usb cable, a lightning and a battery like icon with a diagonal line in it. Not really sure what does that says…
Why a diagonal line, does it says "I am connected to a charger but I can't charge the battery" ? o_O I guess not, but…
