Alright I have tried everything in this thread and the others with zero success.
This is what I am trying to do.
I am trying to do a full refurb of my US Cellular US998 LG V30+ so I can relock the bootloader and sell it online. I have recently upgrade my phone due to the whole Verizon CDMA sunset thing and the LG models are going to suck later down the line.
Anyway I can see the phone in LGUP in every mode EXCEPT for download mode.
As soon as it goes into Download Mode, it does not appear in the device manager and subsequently does not proceed to flash because of that.
I have tried manually going into Download Mode (Vol up plus plugging in with cable) Tried different cables, different types of USB ports (USB 2.0, 3.1). Reinstalled the drivers after a full registry clean and device manager hidden devices clean. re-installed all the different versions of LGUP that are posted in this thread and the others...
All do the same thing. Cannot see the phone once its in download mode.
Does ANYONE have any suggestions at all on what to do next?
I mean I CAN just sell it as is, but I would rather it be fully back to factory before I did.
PS. Also not a newbie to this crap either. I was a service Tech at US Cellular for 9 years before they got rid of us all due to them starting to sell Apple devices (They'll tell you its not, but it IS because they didnt want ANYONE repairing those devices and we were all let go mere months after starting to carry it - NOT coincidence). Also still do phone repair on the side from time to time, but this issue has me stumped.
If you have TWRP, flash the US998 20e TWRP-flashable zip and that will restore LGUP Download mode. Then you can flash a full image KDZ (like US998 20h) and use ADB commands to re-lock the bootloader.
