@Keneda yes, because I would trade with my phone (which is much better). But you didn't answered my question.

Hello! When i first started to hear about Ubuntu on Lg g6, I imedietly jumped to my mom's phone to try it out. I'm just a begginner and know absolutely nothing about how to install this OS. Can somebody help me?
I already unlocked my phone, and managed to install twrp (idk if I did it okay). My phone model is h870, EU version. I'd want to experience the Ubuntu OS at the earliest possible moment. Thanks!
