Does it really have to be a .BIN file?
Would it work to use the UpTestEX_mod2_marwin.exe tool from
here to convert this .CAB into a .KDZ file and then flash that .KDZ file using KDZ_FW_UPD.exe (from the same post)?
Or would it work if you took it a step further and converted the .KDZ file obtained using the above method into a .TOT file using the LGExtract tool from
here and then flashing the .TOT file with LGFlashTool using the .DLL for the F3 from
here? I know LGFlashTool works with .TOT files because I used it to downgrade my LG Volt (LS740) so I could root after accepting an OTA update.
Was just curious because I couldn't seem to find out how to convert the .CAB file posted here into a .BIN file.
I'm too afraid to try this suggestion myself, but I thought I'd throw my idea out there in case anyone else wants to try to utilize this .CAB file. I plan to use the unbrick guide to return to stock V7, accept the OTA update, and then re-root using StumpRoot and reinstall CWM Touch.
