somehow, I seem to be too dumb to install TWRP to my new dumpling. I did the following:
- run the official updates (9.0.3 Pie)
- unlock the bootloader using adb
- successfully flash the latest TWRP recovery (twrp-3.2.3-1 dumpling from their HP)
So far, no problems at all. Then I booted directly into recovery, so it won't be overwritten again: I tried unplug + Power/Volume Down, command "fastboot reboot recovery" and selecting recovery from the menu. But everytime I end up with the beautiful stock recovery, I never even saw the TWRP interface.
Any suggestions ? Any help would be much appreciated!!
My only idea: The latest TWRP is from 08/2018, maybe its not compatible to Pie ?!
