1、修改路徑：frameworks/av/media/mtp/MtpServer.cpp

2、修改方法：

MtpResponseCode MtpServer::doGetDeviceInfo() {
     mData.putString(string);   // Manufacturer
 
     property_get("ro.product.model", prop_value, "MTP Device");
-    string.set(prop_value);
+    string.set("你要修改成的名稱<span style="font-family: Arial, Helvetica, sans-serif;">");</span>
 

     mData.putString(string);   // Model
     string.set("1.0");
     mData.putString(string);   // Device Version
