Am I correct that you are showing no fails on your terminal?
So the next instruction is
Manually reboot into recovery mode
The next workflow may look odd first time you see it.You are required to do button presses to boot to new recovery – without wiping your newly flashed “recovery” partition.
Any action to do a regular boot to recovery will result in “boot as standard” – this would be bound to fail.
I don’t know this device but check out the “hypothetical” as explained for a Samsung.
