hmm... I guess I'll have to look beyond form factor then xD. I don't know whether ZTE makes any other Android flip phones, or any other manufacturer, really (except Samsung, I guess).
Lollipop doesn't look too promising for perm root... Anything for kernel version 3.10.49 (November 2016)?
Man, ZTE did well on their part... I've read about people somehow being able to flash TWRP + CM11 on their ZTE phones and then disable write protection, and others who did it the other way around. I just got an unlucky combination, ehh? Lollipop and write protection.
I have the kernel source, but I'm not quite sure what to do with it... If I were to mod the kernel, wouldn't I need a special key to sign its .zip in order to flash, given that the stock recovery actually works?
