I am actually lying now that I think of it: I did flash through recov menu but that did not work, would not boot as for some reason after the first initialization stages, which showed 1.5, it said switching to rootfs uruk 1.0 (?!).
I had to download full install pack and perform repair/reinstall of 1.5 through recovery menu. That worked fine. Apps and settings were still there & fine.
