  1. I tried this now using your prepared image and what actually happened was I lost root after flashing the zip via twrp, and i lost twrp as well. bugger.

    • @mcfrog:disqus you can create your own file and flash that. The file linked above is taken from another source.. so I can’t really say anything about that.
