I am trying unsuccessfully the method mentioned above without any success since yesterday night.
If followed carefuly the steps but when launching "LGDP2_V36_UMTS.exe", I can't enter Emergency Download mode.
Everything is well installed, my modem was located in port COM4, I have the correct DLL and .dz rom.
But when I press the "Start" button, and plug in with the USB the phone when LG logo appears at startup, nothing happens.
If I set the "USB Switching" to QC Composite, using MFG, when connecting the phone, ports COM5 and COM6 become active (still nothing on port COM4) in LGDP2_V36_UMTS.exe, I get "ErrNum502 EMERGENCY MODEL FAIL" after a few seconds.
Any idea on this? I am currently running an LG Optimus 7 under NoDo Orange-FR branded (would like to flash with the European rom).
Thanks in advance.
