Yes! → In TWRP Recovery this command is provided.
The /e/ documentation would be clearer with a few some additional terms (added by me in bold font).
- Manually reboot into recovery:
- With the device powered off, hold Volume Up + Bixby + Power. When the blue text appears, release the buttons.
On some devices, installation can fail if vendors are not up-to-date. In this case, please:
- Download those vendors
- Install them
- On the device, go into TWRP Recovery
Advanced>ADB Sideload, then swipe to begin sideload- From the computer ADB¹, please run
adb sideload <vendors file>
Note: Be sure to reboot into TWRP recovery immediately after having installed the TWRP custom recovery. Otherwise the custom recovery will be overwritten and the device will reboot (appearing as though your custom recovery failed to install) - usually the stockrom Android recovery mode is then displayed again.
