It could work... Or it could throw you into a boot loop again. Its kind of a trial and error thing. If you got out of the boot loop using the LG Flash Tool, then you are probably in good shape to try again with Cyanogenmod. If it gets stuck again, just use the flash tool to restore to stock. Make sure any personal data is backed up before you try it, but that should be a step you take anyway. If you are familiar with the flash tool, then I would suggest you download one of the older stock ROMs that you know is compatible with Cyanogenmod and flash it using the tool. There are some good tutorials on here explaining each step thoroughly.
Sent from some kind of EVO with some kind of custom ROM.

I do basic tutorials on stupid and simple hacks and mods for phones and tablets and all kinds of things.
