If, perhaps, you used an image for pinebook vrs pinebookPRO,
then this is expected (these devices have different cpus and different uboots)
Try a long press, press/hold pwr button +20 s, then regular 1s press
If uboot has been written to emmc you will have to remove/disable the emmc
This has happened to me, 2y ago or so

I am assuming that you get NO leds except charge?
