Since I have connection issues (I live in China, where nothing will download properly except if provided a mirror inside China), I have downloaded the Clockworkmod Recovery image for mako, the installer.zip, and followed the instructions inside dualboot.sh manually: I had Cyanogenmod so SU was already there, etc. The situation now is, I have the Ubuntu Dual Boot apk installed on Android, and running fine.
But now I have a connection issue I cannot solve: the download is getting started, the small images like image-master.tar.xz and image-signing.tar.xz downloaded fine, but I haven't been able to download the big image ubuntu-[long-hashtag-i-wont-copy-here].tar.xz.
So my question is, is there another way to download this image (if there is only one, I don't know what comes next) and to flash it manually? Thanks in advance!
