Upgrade SE K610I (CID53) to SE W660 or higher?

I want to upgrade my SE K610I to W660 (or higher if there is any). But I need some advice and answers.

Q1: Besides W660, are there any higher model I can consider upgrading to.
Q1: Will upgrading improves on the sound quality and camera quality.
Q2: Can I enable radio reception with the upgrading.

I am very new to this stuff. My K610I has been upgraded with CID53 from SEUS and I have JD Flasher (V30.6.08), SEtool2Lite (V1.11), XS++ (V3.1), USB Flash driver for PC. Can someone kindly post me the STEP BY STEP procedure, and where, what files (main, fs, etc) I must get for the upgrading.

Q4: I learnt that certain .jar files (like Doc Viewer 1.0.9 SE or Moby Explorer 3) can enable my K610I to view MS Word files. How to install such files, do I install them as if they are FS files?
Many thanks in advance.

Pls. message me if anyone can do it

Hi
Q1: Not that I know of but i just flashed a K610 to W660 so im not fully up to date.

Q2: I really can't tell yet, but then i don't use SE's own Cam and Acoustic files but custom files that hard working people have released for us.

Q3:Well i can tell you as much as radio won't work, that is if you convert K610 to W660 because K610 doesn't support radio at all. It's in the hardware you know.

Q4: I don't know if Moby Explorer can view word files, haven't tried. But you install moby explorer as any other .jar file.
Just upload it to your phone, somewhere, doesn't matter and then just click the file in the phone and it installs.

As far as flashing your phone to W660 firmware... you have CID53 you write.. im not familiar with that CID and its procedures so sorry i can't help you on that one.
Best of luck though!

Problem solved. Thanks everyone.
