wanting your cake and eating it too eh?
then the above thread and prog. is the best option.

but you should know this if you have an n900...

and before posting
"But I have no access to the applications in the first place to download them..."
as rebuttal.

download the prog onto your pc...
including any dependencies needed..
transfer them from pc to phone ...or pc to sd card and put it in your phone...
install the dependencies...
install the program..

run it.
back up what you wish to.
reflash.


of course ...
the big big BIG issue you may have is you should have utilized backupmenu a long time ago...
Before you ever began having the 1st issue with your n900...
since...
backupmenu cannot repair damage done...
But for you...right now...
it will make a perfect os snapshot of your fcuked up system.....
so you can reinstall it at a later date...
Backupmenu snapshots should have been done when the system was functioning nominally ...

your issues won't get solved by backing it up.

and your issues... ...
I must admit ...are quite impressive...
they are like a lovely pretty-pretty cascading waterfall....
of accumulating things left unaddressed...
Leave it awhile longer ...
and tell us what happens next ...

film it if you can....
I have never seen an n900 handling so many issues as yours implode and suck itself into another dimension before

or take the sane approach and manually copy the non-systemic files you need to.
reflash.
reinstall your apps.
copy said files back.
and then use backupmenu to make a snapshot of an os that is actually functional.
before you go down the same road again....

personally ...
I want to see film of your n900 going where no n900 has gone before...
