Hi there friends.

I fixed my previous problem. I used the USB+POWER adapter cables and connected my dead (IR port RED light blinking) SE K810i to SeTool (the current version). I followed the guide on reflashing my mobile phone's FS, MAIN and CUSTOMISATION. All went well becuase, and I assume this, of the USB+POWER cable combo: the phone did not disconnect anymore.

Now listen up you Noobs out there (this is coming from a Noob myself);
Curiosity killed the cat, or in my case, curiosity relocked my perfectly normal and working SE K810i.

Here is what I, ever so curiously, did:
1. After doing my victory dance and at the same time screaming "Who is your daddy!" to my previously dead SE K810i, I went ahead and downloaded SUSE (SE Update thingo).
2. I then connected my mobile and the program upgraded its firmware to CID53.
3. My SE K810i is locked again - at least it's not dead anymore.

Now I did do some research, and I found:
1. No current program can unlock or patch CID53 (DB2020) phones.
2. There are Pay options for this I assume.

I just want to be 100% sure on this, and that is why I need expert advice as to my latest predicament.
1. Are any programs currently being made to handle CID53 (DB2020) in terms of unlocking or patching?

Any assistance would be greatly appreciated.
