Yes. However the AV300 firmware is actually two AJZ files concatenated and the committed code only extracts the first of those. You can split the file manually and descramble the second part separately (both files start with "ZCZC").
The only plaintext I've found in the second part is right at the beginning: g_pDSPCode_SEP_CAPTURE. Either it simply doesn't contain any more, or the descrambler is buggy. The XOR string looks good though.
