Root Soft Bricked when trying to Repartition Internal memory

Been busy for a while, but now I'm back... Thanks for asking :)
I'm in a dialog with crutchcorn right now, but now when this thread is opened, we should really share everything here for all to see... Maybe my problem will happen to someone else sooner or later???
 
So, after I messed up (soft bricked) my phone, by wrongly mounting/unmounting during repartitioning the system - this is what I've got
Userdata and cache is gone and the rpmb (whatever that is?) is wrong size?
I can reach adb (twrp) and fastboot (download mode) and I've already tried all possible methods to restore laf, aboot, boot and different recoverys, even the stock recovery? Restores alright, but I can't get to stock download mode with button combo (a ms323 thing I believe).
I believe my last resort would be to learn (if it's even possible) how to create/repartition/resize partitions in adb? Or if it's possible to flash userdata.img and cache.img (if someone can upload it)? But I assume I have to create those partitions first?

Grateful for any help ☺

Maybe it's possible to make a flashable script (in twrp) to stock partition sizes?

If it's not about USB cables or drivers (tried plenty) there's the problem I've heard that more ms323 users have: download mode won't work - even after properly restoring laf and all available recoverys? It always ends up with fastboot only
My next mission is adb / parted, to recreate those missing partitions (userdata and cache)...
 
Solved ☺
Couldn't have done this without all the brilliant help from: @Kamil Mazik, @DevMyAndroid, @Shahell Salvin Deo and @crutchcorn ☺

Thank you so much guys!!!

Even before this problem, I never solved the restoring of laf (download mode), but thanks to Kamil Mazik's recommendation to flash an older twrp:

it worked ☺ Well the actual flashing of the laf.img worked before, but now the download mode works ☺

I'm not sure if it matters, but crutchcorn shared the proper ms323 laf.img if needed:

laf.img (ms323)

And then the flashing of ms32310c works at last:

And please, straight after unlocking bootloader, restore laf, so you'll keep download mode - it makes everything so much easier (in case of brick)

And after rooting and unlocking bootloader (again, puh) the repartition worked flawlessly with PhilZ recovery thanks to Shahell Salvin Deo's post:

Have in mind that if you want to restore a ROM backup after repartition, make sure your backed up system aren't bigger than the repartition makes it and also, I think it's important that the ROM backup was made with the same recovery that you will restore it with.

I'm obviously not 100% sure I found the best ways here, I'm just a noob trying to follow advice ☺

Good luck ☺
