Key Findings

• The ZIP password for the recovery archives is SMDCONSUMER, encoded in .SCP script files using a three-step scheme: length prefix in the low 5 bits of the first byte, XOR each payload byte with 0x03, then reverse.
• The serial number screen accepts any 12-character alphanumeric string -- the real access control is the UIA sector written at the factory, not the serial itself.
• All protection-relevant executables are compressed with either PKLITE (QR.EXE, CPQZ.EXE) or DIET (UIABOMWR.EXE) and must be unpacked before patching.
