Everythings is here https://github.com/tchantchan/Ubports-Onclite-redmi7 for the files to flash.
Unfortunately the Mashkoukras vendor v2 is listed but offline.
I bought a Redmi 7 (not a Note 7) to install Ubuntu touch. You mentioned it is an Onclite, where did you get this information? There seem to be different versions. I'm not sure if mine is compatible.
I'm a total noob in flashing a smartphone. The instruction on github is for users who have experience. You wrote that you followed this website you mentioned but what to do from there? I don't know where to start.
The first step on the github page is to 'Full wipe and format data'. What is meant, personal data, format to some filesystem (how should this work) ? Oh yeah and the link to the second step is broken.
As you see, I have a lot of problems with the installation. I regret that I haven't bought a Note7 which has an installer. But hey, I didn't know how to handle Linux on a computer few years ago but I learned.
I hope you or someone else in this thread is able to help me. That would be awesome!
