FYI: Pie OTA update from Oreo to Pie helps me fix 'Download mode' on my H932 with stock Pie.
Preconditions: H932 with stock Pie and unlocked bootloader(in my mind bootloader status doesn't matter), without TWRP and ROOT.
Steps:
1. Install LGUP Dualmode https://forum.xda-developers.com/attachment.php?attachmentid=4848229&d=1571410779
2. Start LGUP with connected phone and select 'FOTA Upgrade' process.
3. Add this OTA file https://ota.googlezip.net/packages/.../0323aec4bf7707855a5f58b85826ec951e3f6bf4.zip
4. Click 'Start' button and wait. If LGUP shows an error and ask you the wpdapi.exe file you can use this https://forum.xda-developers.com/attachment.php?attachmentid=5053209&d=1593797990
