Hi, I’m trying to install TWRP on a Galaxy S9 GM-960F with Heimdall to eventually install /e/OS, but I can’t seem to find the right key combination.
While in download mode I type this (as root on Linux) and it doesn’t give any error:
heimdall flash --RECOVERY twrp-3.6.0_9-1-starlte.img --no-reboot
The problem is finding the right key combination to boot into TWRP.
Then pressing VolDown and Power powers it off, and I immediately switch my finger to VolUp, but with no avail. Sometimes it boots into the default recovery after erasing TWRP, sometimes I wait for the fabled blue text on the top of the screen to release them according to this Howto and this one, but instead it gets stuck in a boot loop (with logo and short vibration several times) until I release them and it then boots into system, and when I boot into recovery it’s still the default one.
Can somebody give precise details on how to do this? I only find vague contradictory descriptions and I’m tired of playing piano with the keys. I can’t understand why there’s such an awful deal of discrepancy and disinformation all around. Even the Easy Installer gets it wrong, telling me to press the Bixby, VolDown and Power key at the same time to get out of Download mode, whereas the device itself clearly tells you to press only VolDown and Power:
