⚙ī¸ Go Back to FydeOS or Standard Images​

caution

Ensure that you have backed up all your data.

BredOS images use UEFI boot instead of the original U-Boot. This means you can no longer enter MASKROM mode by pressing the Volume Up + Power keys. Instead, execute the following command in the terminal (THIS WILL COMPLETELY ERASE YOUR DATA):

sudo dd if=/dev/urandom of=/dev/mmcblk0 bs=10M count=2

Now the tablet should be in MASKROM mode, and you can flash the standard images. If needed, refer to the Unbrick section in the Fydetab wiki.
