1st being 1st, check the dl file. If not possible, re dl again. and post your system info. I think you are doing N810 and tried to install MMC boot into internal SD, right? I do not know which one you are using, here are the byte size on a winPC install-tools.deb 3,743 install-tools.ad.tar 5,774 install-tools-N810e.deb 3,744 And sure, you have only ONE EXTERNAL.txt or INTERNAL.txt on your system, right? I think this is not important, though bun
