Was going to edit my first post, as I just realized that (what coderus mentioned above).
recovery mode: just read the article to the end and remembered about using putty/telnet (forgot that on-Jolla-screen is only logo)
nemo is the user to connect with ssh (checked: working)

Going to fix soon...

Was there not a post of you (coderus) where you explained how to disable all patches from command line?
Do you know which packages by name I should try. In which order?
TIA
