How to enter flash mode

Contrary to non-waterproof eBook readers, the Libra H2O does not have an internal replaceable µSD but an internal eMMC, so things have to be flashed on the device. On factory uboot fastboot mode can be entered using pagedown while powering on. Alternatively using the serial console and enter fastboot 0 on the uboot prompt. Note: if nothing which looks like a bootloader is found on startup, the following device

hid-generic 0003:1FC9:0128.001B: hiddev1,hidraw1: USB HID v1.10 Device [   NXP    SemiConductor Inc  SE Blank 6SLL] on usb-0000:00:14.0-6.1/input0
