When i install these files (mcsgeek post) i have a nand flash with 0 B (it should be the ext sd card with 8 GB) and a sd card with 567 MB (the same space the nand flash was before the system modification) the external sd card seems to be not recognized (for information my anvova 10b g3 is a 4 GB and i have install the 4.1 with more space for apps of this site and the sd is a sandisk 8 GB classe 4)

I post here the VOLD.fstab (i have write in red the differences between my file and the line in the post in blue)

Do you know what is the probleme with my file. Must i "rename" sdcard to flash, must i insert the "?" or the "/mtdblock9". I am careful because when i first test i "bricked" my tablet and i reinstall everything.

Thank a lot for all these solution and your answer.

Hi I have tried to download the kasty f ile but it came as arctablet.php and not supported ! I have done the google play succeessfully last year. Sorry "download.php

Having read it again it does sound  a bit odd! I was in a rush and the keyboard was slow, it is now. I had downloaded the "kasty" file and "rockchip"  to my tablet but in the download file they were named "download.php" and when I tried to open them it showed "file not supported". So my post. However, later I "renamed" them with the correct names and were then OK.. Only then did I realise that I should have downloaded them to a separate computer, this was not immediately clear. I don't have another computer at the moment but when I do I'll give it another try. Hope this makes more sense.Sorry for the confusion. Cheers!
