you cannot use a tm30 registration as you are not in Thailand.
The tm30 is registered when arriving in Thailand and you don't have a Visa/extension to continue it. Even when I return I update my Tm30. In fact just registered in the new system tonight.
If you provide the Tm30 at the same place they can make the argument you are trying to live here on tourist entries.
What I have heard that works is an invitation letter from your G/F, with her ID and house book.
Stating how long you will be with staying with her.
Given your history not sure I'd go that route.
Short of that just book cancelable accommodation do a couple weeks.
If your thinking of retirement, I would get the 90 day non-o and enter on that, no issues.
You are guaranteed 90 days even if you don't do the extension.
There is even a multiple entry non-o based on retirement, good for 1 year. You have to exit every 90 days and can extend to 1 year on any of the entries.
IF another office is willing to look it up in the system and IF the entry information is recorded correctly BUT the stamp is just wrong, they may correct the stamp.
If they recorded you as a Tourist entry could be problematic.
Most times they will want you to go back to the entry point and fix it there.
Nobody wants to take ownership/responsibility for another's mistake.
It will up to the individual office/officer discretion.
