Hello everyone,
First of all, sorry for my poor english. :)
I have a phablet which installed ubuntu touch 14.04(another person did this work 2 years ago, he modified the kerner, uboot, and so on, but he has left already, and I don't know what he actually did), and now I want to upgrade it to ubuntu touch 16.04, Does anyone know how to achieve this goal?
I flashed the original kernel, ramdisk.img, initrd.img and recovery.img to the device and the phablet can boot to recovery mode. and then , I download the new xenial-preinstalled-touch-armhf.tar.gz from cdimage.ubuntu.com, tpying: ./rootstock-touch-install xenial-preinstalled-touch-armhf.tar.gz system.img, but it doesn't work, Do I need to rebuild all the stuff ? Or just replace the Ubuntu root file system like rootstock-touch-install did?
Thank you in advance !
