Not only that one click applications don't work on my phone, I want to DIY root my phone. Upon googling for quite some time, I couldn't find any updated guide. I am willing to write one myself, but please point me in the right direction. All I get when I google are either noob rooting guides or outdated information. What should I look for? How do I root the linux box?
If it matters, I have a Lenovo P780(Android Version : 4.4.2), and my PC runs both Ubuntu 14.014 and Arch Linux. I have adb and fastboot installed. I didnot manually install any phone drivers. Firstly I tried unlocking the bootloader by rebooting the phone into fastboot mode and trying a
sudo fastboot oem unlock. The program doesn't do anything. No output.
Since my phone is MTK based (MT6589), I've tried Framaroot, but it fails with error #9. I remember that in the past when it had stock jellybean, the app worked, but after subsequent updates and upgrade to KitKat, not only did I loose root, but also the exploits might have got patched.
