常见问题解答
JMF612的Xor值是多少？
根据文章内容，JMF612的Xor值为6771_1，这是数据恢复过程中用于解码NAND闪存数据的关键参数。该值在配置Flash Extractor或Oracle Extractor时需准确输入，否则可能导致数据读取错误或恢复失败。建议在软件中直接选择或手动输入此Xor值。
JMF612的块对和页大小如何设置？
文章显示JMF612的块对（Block Pair）大小为0x100000或0x200000，页（Page）大小为0x1000或0x2000。具体设置需根据芯片型号（如2c 68 04 4a或2c 88 04 4b）和实际布局（Layout JMF616 1070）来确定。在工具中应选择对应的块对和页参数，以确保数据提取的完整性。
JMF612的输入顺序和混合参数有何作用？
输入顺序（Mix Input Order）如4/2/6/0/3/1/5/7/10/12/8/14/13/15/11/9，以及混合参数（Mix）如8/0x1000 2/0x10000，用于定义NAND闪存中数据交错读取的规则。这些参数直接影响数据重组和恢复的准确性，必须根据文章中的具体数值进行配置，否则可能产生错误的数据偏移。
