Problems with Tolino Shine 4

[krahiner]

Hi Waldy / everyone,

I'm trying to revive a soft-bricked Tolino Shine 4. The original internal SD card had bad sectors and completely died. I tried to clone and nothing. The screen is totally blank.

The label on the motherboard near the battery says +6A1.

When I plug the e-reader into my Linux laptop via USB, lsusb detects it as 1f3a:efe8 Allwinner Technology sunxi SoC OTG connector in FEL/flashing mode. So the hardware seems alive, but it's stuck waiting for a working bootloader/image.

Does anyone happen to have a working factory dump for the Tolino Shine 4 (+6A1 board) that I can flash to a new SD card using dd? Or is there any low-level recovery method I could try?

I want to try also a 32gb sd card.

Thanks in advance for any help
