 Please connect your Toniebox to your Wi-Fi and update its firmware. Many boxes are shipped with a production firmware that needs to be updated. Otherwise the box won't work as it should.

+You'll have to manually extract it from the flash of the box with a SOP8 clamp directly from the memory or by desoldering it. Reading in-circuit can be tricky, but is possible. I recommend flashrom as tool for that.
+
+## Reading the flash with Pico
+As a probe you may use a raspberry pi pico with the serprog protocol firmware for it. It may be downloaded from the [libreboot project](https://rsync.libreboot.org/stable/26.01rev1/roms/libreboot-26.01rev1_serprog_pico.tar.xz)
+```
+flashrom -p serprog:dev=/dev/ttyACM0:921600 -r tb2-flash.bin --progress
+```
+You may do multiple reads and compare the result
+```
+flashrom -p serprog:dev=/dev/ttyACM0:921600 -r tb2-flash.2.bin --progress
+diff tb2-flash.bin tb2-flash.2.bin #no output = equal
+```
+
+## TBD
+The certificates in the flash are encrypted. We are working on a solution to decrypt them.
