I've installed ubuntu touch on my nexus 4 by flashing two zip(Armel + Mako and Touch armhf) files directly from the cwm recovery. I wanted to dual boot my phone with the existing rom(4.4.2 n5 port). I stared with the procedure given here. https://wiki.ubuntu.com/Touch/DualBootInstallation But then my carrier data speed was kinda low so i downloaded .zip files on my laptop and the flashed them. now the phone seems to only boot into ubuntu only. How can I dual boot the phone now without going through the procedure of downloading ubuntu through phone? Is there a way I can use the downloaded files in my phone in the ubuntu dual boot apk?
