Thanks admin,

in deed i read all the posts

if u mean this one: http://www.arctablet.com/blog/forum/arnova-7-g3/locked-arnova-7g3/

u can see that there was no answer but this "I actually sent my 7g3 into Arnova/Archos for a warranty issue"

or ur: "...without result"

or "..make their own firmware dump" which i tried but can't get it, bcs it was not clear for me how to do it... i think most of the posts (in dumping post) was not talking about locked devices, as they can open settings to use adb...

i tried "LiveSuitPack" with the images (nandX) but it says: "image file invalid"!!!

so, is there a post talking in details for beginners how to dump locked devices please?

and thanks again...

(i didn't read all the 13 pages in http://www.arctablet.com/blog/forum/arnova-7-g3/original-firmware-dump-anyone/, so if it's there please help me to locate)
