It's possible with iRoot... There is also a recovery with a better disk partitioning just in case in "needrom" website. If you do, please share the original rom with us on needrom, there are no info or custom roms for this phone yet.
Hello !!!! Can someone help me out? I have the z550 and I can not do my updates. It displays an error that does not have enough space. And in storing phone I have 4.98 gb. and 28.5 gb sd memory. I can not do is install and configure not all in the internal memory, it is the fault that I have.
I hope someone can help.

It's a good phone, worth the price, but not the best thing ever. If you like the freedom android offers (root) then you will not be happy, I haven't rooted mine but I read it's complicated. You cannot update to lolipop, plum will never release the update really, and there is no room from the community, I haven't tried with cyanogenmod but I don't think that will work. If you have the bucks go buy an LG G2 or G3.
