Not sure if I should start a new post or add onto this long thread.
First off, thanks to those who’ve come before – there’s a lot of really helpful stuff in here.
I have an ER605 and likely will have quite a few more. I am really keen to get them all on OpenWRT. However, before I can, I need to prove that I can safely flash to OpenWRT and back to stock reliably. I understand there’s some complications with this and I wanted to confirm before I continued.
As per chill1penguin's guide, step 4 recommends a full MTD backup, which seems sensible.
I have root access.
From another Linux system (WSL) I am able to create and run the full backup script mentioned. However, there are problems:
$ ./mtdbk.sh
Opening master SSH connection

I have noticed other mentions of ubiformat to restore the backup and I hope to test that… but first I’m not sure how to actually get the backup (with the recommended script above failing).
Any pointers to assist me in getting the backup would be appreciated. I am not sure if this router needs modified instructions, or I'm missing something.
