After using “flash-all.sh” to flash (including boot.img, super.img, userdata.img, fastboot reboot), adb devices came up fine, however, HDMI screen went black. Tried to flash the previous working image, could not bring back display.
Tried:
fastboot oem select-display-panel hdmi
fastboot reboot bootload
→ can bring back “FastBoot Mode” display
However, after “fastboot reboot” → the screen becomes black again, even though “adb devices” is fine.
