instead of using KDZ, i used lg R&D tools (or something like that) and there was an option to merge a model.dll file and a DZ file together, and then flash it.. i did that didnt know that they were mis matched and didnt belong together untill AFTER the test was done, it gave me this:

After this frightening log my phone shutdown and has been IMPOSSIBLE to boot on since then. its been a week and ive tried about 40 or 50 different methods to fix it and/or boot it on. after research JTAG is the only thing that can fix it.
