Reflashing -- the same as restoring factory settings, isn't it? -- should be fine with my device anyway, since I haven't really used it enough to lose much in terms of settings or data.

It's also sort of another last resort. If that doesn't work, I'd have to send it back to Nokia, I would imagine.

I'm not particularly keen on installing every app manually, either. So even if rootsh allows me to install apps, I'm not sure I'd want to do it that way every time.
