高通8994平台的NV到底是储存在哪个分区？

网上有人说是Modemst1,modEMSt2,但是实际上这只是两个缓存分区，fsg是所谓的golden backup,我wipe掉这三个分区，开机用QPST依然能备份出来正常的NV，有没有真的做平台出来的给个准?业外人获取不到高通保密资料，有人知道的告诉下那就是事半功倍

修改NV06828 1877总是会还原说明机器里面还有一份很底层的NV备份

这问题困扰我很久了，有时候备份不了EFS操作起来都提心吊胆的

这个好像是每次modem reset的时候抓到的NV重载过程，也不知道具体流程是怎么样的

希望能有高通平台的工程师出来说个准，网上都是些民间说法，感觉都不靠谱

我最近也被这个麻头皮，修改了xqcn文件后，restore了。还没重启就发现还是原先的那个：重新down下来一看，就是原先的那个，而不是我修改过的。

我的机子是msm8976，你说的分区都处理了，包括厂商自己的两个和NV名字关联的分区
