Here is the dump from when I try to flash ubports:

Can't boot recovery image
Each time I have wiped the cache folder using TWRP, so for me it is a mystery why other people like you can successfully flash an android meizu pro 5 but not me.
My problem was that I flashed canonical image on a stock chinese android meizu Pro 5, after changing the firmware to international, etc... Then at some point I broke my screen and it took me a few months for getting a new one. When I came back, canonical had discontinued ubuntu touch and ubports was just starting. When I couldn't flash my phone two months ago I figured I would wait for the community to have improved tools, but it seems I'm not yet there, so I think I migth have something strange going on over my partition structure although I never did touch them (so this should be the same stock android partition system.
The only thing I found out about the scatter file is that it is supposed to be the mediatek MT 6795 scatter file, but the only thing I found on the web was this link for flashing android: http://flashromandroid.top/2017/03/4767-simple_step_flash_android-meizu-pro-5.html
Again, I am simply not familiar at all with the concept of scatter files, which is why I thought about asking for help here. Unfortunately it seems I have a very specific issue with my phone though, so it's a bit frustrating on my end :).
