Hi everyone,

I am investigating a seemingly bricked PocketBook Basic 2 (614). The screen has only shown the Basic 2 logo since I unboxed it, power and navigation buttons are unresponsive, not even the power led lights up when connected to power. I tried various combinations of holding down buttons. I only got some clues by connecting via USB to Linux:

Code:

❯ lsusb
[...]
Bus 001 Device 007: ID 1f3a:efe8 Allwinner Technology sunxi SoC OTG connector in FEL/flashing mode

Code:

sudo sunxi-fel version
AWUSBFEX soc=00001625(A13) 00000001 ver=0001 44 08 scratchpad=00007e00 00000000 00000000

And information on the chip from sunxi wiki: https://linux-sunxi.org/A13

Ideally I'd like to restore the bricked device to a functional status if possible. I have an identical PocketBook that works and was hoping to somehow clone information from the functional device to the bricked one.

I also don't mind flashing some other image on the device, whatever works. I tried following some tutorials on the sunxi wiki, but this is way above my knowledge level. If someone has any tips or ideas where to look next, I'd be grateful.
