Ehh... why?
I don't have time this year because this is my last year in school and I have lots of exams with much theory (not very interesting) and I have to study a lot.
I do not even have time to develope for my own device. I started working more on Xperia T3 because that device has less support than T2 Ultra, but I have not finished. I have many remaining projects to continue and improve, but until second half of June it is probable that I will not be able to work much on this. I created basic support on device trees and added some things on kernel, but this process is not easy for one person and different devices.
As soon as possible I will continue working on it, but please do not say stupid things such us what I say is a lie.
If I give up, I will clearly say it.
By the way, I have created a group on Telegram for development. You can join in
