K800 after SE Update Service locked again

Hi, stupid mistake. I had a vodafone branded phone which I unbranded to generic CID52 phone and applied unlock patch couple of months ago. For stupid reasons, yesterday I used the SE Update Service and now the phone is locked again and the CID is 53.

Can I still apply a CID 52 Main Firmware and then generate and apply new unlock patch or what are my options?

Here is a screenshoot from XS:

You can downgrade CID with D-Unlocker.
But CID 53 can be patched too.

you are saying that CID 53 can be patched too. can u please explain how.
can i flash the phone with xs and cid 52 main and fs. or should i use the cid 53 main and fs?
how can i apply the patch?

the first time i unbranded and patched my phone, i used xs and simox's patch generator.

can use this tools for cid 53 again? if not, please explain the process and the tools I need.

appreciate ur help, thanks again.

I am new at this, and currently looking at doing something simular. If you want to patch CID53, take a look at theese posts:
