Several questions @ K810i

Hello,
Bought my k810i recently, and I started to look for some stuff for modding.
I had k550i once, with this phone modding was easy, but now, as I own this with CID53 inside (doh), its getting really problematic.

My Phone Info:
11:58:48| Profiling SEMC phone...
11:58:48| Platform: DB2020
11:58:48| OTP CID: 51
11:58:48| EROM CID: 53
11:58:48| EROM Color: Red
11:58:48| Phone ID: K810
11:58:48| Region: BALTIC
11:58:48| CDA: CDA102779/53 R4A
11:58:48| Firmware Version: R8BA024
11:58:48| EROM: R3A022
11:58:48| Ready for operation!



So I want to ask several questions:
1.As far I know, k550i and k810i both have DB2020, So FAR + JDflasher is so far so good, right? Or better Se2Toollite, or maybe New XS++ has been realeased? (Got both tutorials for JDflasher and Se2Toollite, dunno what's better to use).
2. DB2020 Can be moddable really much (experienced with k550), So can my k810i have flash menu's & etc.?
3. As K-series model, it can be flashed to w series (closest brother is w810i), but in other forums I heard that it would make k810i camera dissapear, or etc(or its only myths), So I wanna find out how about flashing to W-series?
4. How to put those .vkp patches to phone? (Is akshay http://forums.se-nse.net/index.php?showtopic=20984
Suitable for this (Well its db2020 too, just wanna make sure that its correct.)

Please answer those questions if you can, It would be really appreciated.

Thanks.

1 jd flasher is the only free tool that works with cid 53 phones at the moement
2 u carnt have flash menus on k800.k810
3u carnt mod and thing from a w series phone to a k810i really

Thanks philzfog.

But then, how about .vkp patches, is there any tut. how to put those patches through JDflasher? What I Found was through Se2toollite, which doesnt support CID53.

u carnt patch with jd flasher why not use the dclient and change ur cid back to 52
