It has all those separate imgs and A parameter file in that one file. It should also be signed I believe.

Nice, thx!

This PDF is the Windows instructions but does say how to get into boot loader mode which I assumed you already did if your talking to the device at all with anything vs ADB. Holding in the small hole near the bottom and pushing in a USB cable.

OK, I've tried the the holding part, but still no device with adb. But it is not important I guess.

No, the battery was ok I've checked it before posting (it was 3.9 V)

OK, so, I've seen that from a radxa tuto ( https://wiki.radxa.com/Rock/flash_th...Recommended.29 ) that we have to use a non-free tool called "upgrade_tool" to use the update.img provided by rvcjew, because rkflashtool can only "flash" and do not update.

So I try to update it with the uf option like that :

root@my.computer:/tmp/Linux_Upgrade_Tool_v1.21# ./upgrade_tool uf /tmp/update-10225.img

And I had an error at the end (sorry, I don't have the log anymore ^^').
Then my mars screen was all black o_O
So I retried, same error, and retried again, and this time it was good (a OK).
The mars rebooted, I've seen a black screen with a circle in the centre with "ereasing" in the center of the circle, then the screen changed with a ¼ left border black and the rest is dark grey. And now, I'm not so sure what to do...
I'll wait a bit then try to reboot it again to see if it will be ok ^^'
