I have been trying to get in to recovery-e. I flash it from Odin, then reboot my phone to enter recovery-e but I get an error screen that says: “One UI no command”. Then it immediately goes back to the stock samsung screen.
Any idea why and how to work around it so I can enter recovery-e?
I have also tried the twrp method, but the system partition does not appear in the wipe section, even when checked in the mount section. So if you know a workaround to that I’m all ears.

I’ve tried this. Odin says I am successful in flashing the phone with recovery-e, but then when I try to boot it up the error message appears and it jumps into the regular samsung recovery screen
please share a photo of the text on the top of the download mode screen.
I think it’s not installing properly.
It’s not downloading… I’ve just realised that my laptop is not recognising the com port of my phone. I’ve tried updating drivers and uninstalling the phone and rebooting… cable is fine, any ideas on how to get my laptop to recognise my phone?
Doesn’t mean you can just omit this step 
… appears to be associated in your screenshot.
It’s actually not recognising the com port if I plug my other phone in either… hmm…
Did you treble check that you are using the correct Odin version? New to me in your screenshot is a web link to Odin Community is that searchable for your error / situation?
I’ve tried 3 different Odins including 3.14.4 and none of them have worked 
Computer is just not recognising the com port.
even if Samsung don’t support Fastboot in bootloader mode, but Heimdall or Odin in download mode, can you find inspiration there → [Solved] Windows does not see my phone in Fastboot mode
Do you mean that the computer is not recognising Download mode or Odin is not recognising com port?
Do you already have Heimdall? Don’t use it for the job but is print pit successful?
