Bear in mind that I haven’t done it but, as I’ll be getting a friend’s expert help with soldering, I’m not concerned. Reading the documentation, they appear pretty confident that the rooting will work seamlessly and, from reading other people’s experiences, it doesn’t sound like there are a lot of issues. It’s really assembling the kit to do the work that is the fiddly bit (but there may be pre-made versions around - worth jumping on their Telegram channel) and after that it should be plain sailing.
