stuck in emergency mode,can't use LG support tool

[connora]

I flashed this rom:
csmg.lgmobile.com:9002/swdata/WEBSW/LGKH5200/AKTFBQ/V10r_00/V10R_00.kdz

I changed some files of my system,installed busybox,now I can't boot.I tried to enter fastboot,but failed,maybe LG closed the fastboot keys.But I still can enter emergency mode,how can I reflash my phone with system.img again?

Thank you guys!

The commands I tried were:
su
busybox df -h

busybox cp -a /data/app /system/sd/
busybox cp -a /data/dalvik-cache /system/sd/ (optional)
busybox cp -a /data/data /system/sd/ (optional)

mount data
rm -rf /data/app
ln -s /system/sd/app /data/app
rm -rf /data/data (optional)
ln -s /system/sd/data /data/data (optional)
rm -rf /data/dalvik-cache (optional)
ln -s /system/sd/dalvik-cache /data/dalvik-cache (optional)
reboot

now I can still use ddms and adb,any way to recover?
I just want to enter fastboot and reflash system.

GO TO https://your.rogers.com/web_auth/techsupport.asp SELECT (LG) AS THE BRAND AND (LG EVE) AS THE MODEL. ONCE THE NEW PAGE LOADS, SCROLL TO THE BOTTOM AND CLICK (LG PCSynce Software for Windows) DOWNLOAD THE SOFTWARE AND IT WILL UPGRADE YOUR PHONE.

IF THAT FAILS

TURN YOUR PHONE ON UNTIL IT FULLY LOADS

THIS WILL RESET YOUR PHONE TO FACTORY SETTINGS!

HOLD DOWN THE POWER, VOLUME DOWN, CAMERA AND THE CENTER MAIN MENU BUTTON DOWN ALL TOGETHER. HOLD FOR ABOUT 5 6 SECONDS UNTIL THE OPTION POPS UP ASKING TO FACTORY RESET.
