Green and blue blinking after some weeks

Hello, i have the problem, that the toniebox is not working after some weeks. It works some weeks and than these leds are blinking:

I cant find these error code in the list, has anyone these error or can help me?

When i restart the power (also open box and disconnect the battery and reconnected it, it works again for some weeks)

Same error woth original or custom firmware.

The bootloader complains about something. Most likely it is a faulty microSD or a fault connection to it.
