Can i flash my phone with this firmware?

[Indy]

Hi,
I just wanted to know if I can reflash my phone (Sony Ericsson W830i) to this firmware(these are the only firmware files I could find for my phone):

W830i_CXC1250705_Generic_R1KG001_Red52_sw_enc
W830_CXC1250714_S_ASIA_LEVAN_R1KG001_RED52_fs_enc

The current software specification on my phone( as seen from XS++) is as follows:
Profiling SEMC phone...
Platform: DB2020
OTP CID: 51
EROM CID: 52
EROM Color: Red
IMEI: 35457901xxxxxx
Phone ID: W830
Region: S_ASIA_LEVAN
CDA: CDA102568/110 R5A
Firmware Version: R1GB001
EROM: R3A016

One more thing. I downloaded these firmware files from a website shenliang or something, I found the link on another website. The exact link was ÉîÛÚÊ*ÉîÁÁͨѶÓ*ÏÞ¹«Ë¾.

When I try to upgrade the firmware through XS++3.1, it gives me an error message, saying that the file is Shenliang encrypted or some error message like that. I don't remember the exact message.

I read on the same website i found the link from that I will have to reflash the phone through the software SEKing 3.0.3.8. I downloaded this software, and I thinks it's developed by shenliang. I just wanted to know, will it be safe if I reflash these files from SEKings software?

I know I should not have opened a thread for this but, better safe than sorry! Thanks for your time though.
