    You change the COM port yourself. If it's 8, you change it to like 1 or 41, I don't remember, it's been a while since I've had to do

    Yeah, change the port number to 41 manually. The video will have to wait until tonight when there's less stuff going on.. Sorry for the delay.

    Does anyone have a backup to the Firmware or lg870-flashtools.zip? Both links are dead and my optimus f7 is currently unbootable due to an amateur error I did :/

    Why don't you use mega instead of these off-brand sites?

    Thank you nice people, as I have restored my F7 successfully several times with this guide after it would get into bootloops, but I am now stuck. When I plug it in to download mode, the LGE COM 1 thing does not show under Ports in Device Manager. Ports don't show in Device manager either.

    Just in case, I did read through other posts and I installed "the latest USB driver for this phone ... LGUnitedMobileDriver_S52MAN314AP22_ML_WHQL_Ver_3.14.1.exe " (post #179). As my phone is bricked I don't think I can do the "USB Debugging & Unknown Sources" step 2 that is asked for in that post. Not sure if any of that matters.

    I do not know what to do from here in order to get my phone working again. Thanks.

    You're either not doing a step or missing usb drivers. Using flash tool or uppercut etc. Is extremely easy. Post your exact personal steps. Not from a guide and we can see if we can do magic lol.

    I saw your p.m. I've been extremely busy today. XP is a 32 bit system so the drivers would conflict as I'm almost positive the device uses 64 bit drivers. These tools are made for a PC that does have the capability to run 64 bit.

    I love Windows XP i made a pile full of joy flashing phones to boost using XP as the tool required a 32 bit OS. Use a friend or family members PC. I'm more then willing to help you fix your device.

    Are you using the correct files? Laptop or desktop? And have you tried different cables and or usb ports?
