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.

Many thanks in advance.

Sorry this is update to my original questions...


I am considering UPGRADING the SE K610I to higher model. I need some advice and answers.

Q1: Is W660 the only model or is there other higher models suitable ?

Q2: Will upgrading improves the K610i to Walkman sound quality ?

Q3: Will upgrading enable radio reception for the K610i ?

Q4: My K610i is CID53, suppose I use W660_R8BE001_MAIN_GENERIC_FY_RED53 and W660_R8BE001_FS_EUROPE_4_RED53, is upgrading simply OFLASHing these files into K610i with JDflasher ?

Q5: Is this Custpack file W660i_CDA102804_86_R2A_Singtel_Singapore compatible with the above 2 files ?

Side Issues:

I want to enable K610i or W660 to read MS Word files.

Q6: Can I use DOC VIEWER_1.0.9_SE or MOBY EXPLORER_3 to enable K610i or W660 to view MS Word, Excel files ? Any other recommendations ?

Q7: These are .JAR files, how do I install such files into phone ?

Many thanks in advance.

Problem solved. Thanks everyone. CLOSED THREAD.
