Tried @edp17 guide but phone stuck at Google logo.
Started fresh with step 0 and stock 6.1(latest official ROM)
Then step 1 and 2 went smooth
Then I think in step 3 something is not clear.
I installed the APK file by double clicking it.
Then followed step 4.
Then 5 and finally 6.
No way to boot.
I think step 3 should more clear and please upload the files in one place where everyone can get them.
Also for now I don't wanna use Ubuntu so in step 3 what files do we need?
Again thanks @edp17 for your time!
