lg e445 can i flash with sp flash tool

hey guys I have a lg e445 somewhat soft brick
it stuck in boot loop no recovery no fastboot
only I can go into download mode
but I have tried to flash with lg support tool, lg software updater etc.
when flashing started it goes to 4% to 5% and then says phone not found
so I want to ask you people
since this phone has a mediate (mtk6575) processor can I flash it with spflash tool
if yes then where I go to download firmware files to be used in sp flash tool
if no then what I have to do to revive phone again
note:- in past I have successfully recover this phone from soft brick 2 times. but this times problem level is little bit high.
help me.....
