Hello all,
Bit of background, I've been rooting phones since my old HTC Hero so I'm not a complete newb... but your help on this would be appreciated.
Got a Samsung Galaxy Note GT-N7000 some years ago, of course immediately rooted it and put on a ROM (non-stock, not CM). Anyhoo all things go well for several years. Late last year I put a new kernel and Asylum 4.4 ROM on it. Again all is pretty well, works as intended.

BUT

I tried to do something which required root the other day and things were not successful. Tried a few bits and pieces, fired up SuperSU app, informed me that root was out of date, flash a new one... tried that, but it failed.

Long story short, I've flashed new kernel/recovery (raw_kernel_r4_j43) and new ROM (4.4.2 SlimSaber), tried flashing SuperSU from recovery, tried FramaRoot... Flashing in recovery indicates success, but RootChecker still indicates that there is no root access. FramaRoot comes up with an error advising me to use the "build.prop" (maybe "local.prop"?) trick. Whatever I've tried is all to no avail. To be clear, the device works perfectly otherwise - boots up normally, runs apps without problem, etc. Developer menus and so on all available. Root access just doesn't stick, and whenever I try to do something that requires root access - change DPI for instance - the app just hangs.

Here's the log from RootChecker Pro:
