Nope you can't flash any kdz since Sprint doesn't share them

    Hi dear driend, can u find the .dll archive for lg g8s? Sorry x my bad english

    Enviado desde mi LM-G810 mediante Tapatalk

    no i thought maybe can customize it from g8 to g8s dll. respectively from V40

    The attached DLL MSI - 1.0.40 - worked for my G8S.

    You need:

    LGUP 1.15 - LGup_cmd.exe
    LGUP DLL for G8
    LG USB Drivers
    LG G8 ThinQ latest firmware

    You don't need to disable anything. Just disconnect battery, then plug in battery and you can connect in download like normal. You need to remove demo mode if you want to turn off device with buttons but if you disconnect battery, just reconnect battery and plug in with volume up and flash it.

    Also this video for remove demo mode with passcode is only to remove demo mode from normal carrier devices (if your device has AT&T icons use this method and device will be good as new, only use my method if model number ends in V - G820V, G710V, etc...).

    I did use Octopus to convert and flash it. I never tried with LGUP. If you have octopus I could share the converted file (*.oct format) but easy enough to do yourself.

    On that G820V , did you have to disable retail mode before flashing G820UM310d_00_USC_US_OP_0731.kdz?

    I prefer armed robbery. Just put on a mask, 2 minutes you are in , you are out. But truck/cargo hijacking is a good source too. Can pay a crackhead to just run out of the store with demo models. There are many ways to obtain them. Definitely not on $80 on eBay. These LG G8 demo models are too precious.

    You have a demo mode device? Where did you get it from?

    I was able to flash G820UM310d_00_USC_US_OP_0731.kdz firmware with Octopus. I flashed a demo model G820V and an AT&T G820UM. The G820UM completed flash successfully but now screen says "OPID Mismatched". The G820V flashed and actually boots into the home screen and changed model to G820UM (but of course no signal because demo model)

    The AT&T G820UM, I still have download mode but no stock AT&T firmware to flash.

    Can I cross flash with this process?
    I've a LG G8 AT&T and I want to crossflash the Korean firmware.

    As far as i know, there is no way to convert AT&T G8 model into Korean variants now.
