定位到framework\com\android\internal\telephony\MMDataConnectionTracker.smali中
关键限制代码在isReadyForData()中
smali代码

if (flag && isDataConnPopupAllowed && !isDataConnDialogDisplayed){int i4 = CommandsInterface.RadioTechnology.RADIO_TECH_LTE;if (i == i4 || isRadioTechEvdo())synchronized (datalock){int j4 = Log.d("DATA", "[MMDataConnectionTracker] isReadyForData is True and isDataconnPopupAllowed is True ");StringBuilder stringbuilder14 = (new StringBuilder()).append("data conn popup showed, ");boolean flag14 = isDataConnDialogDisplayed;String s4 = stringbuilder14.append(flag14).toString();int k4 = Log.e("DATA", s4);createDataConnectionDialog();}elseflag = false;}可以看到
int i4 = CommandsInterface.RadioTechnology.RADIO_TECH_LTE;if (i == i4 || isRadioTechEvdo())这个是关键判断，若非LTE或Evdo则flag=false;也就是不能上网
那么我们只需要去掉这个判断就可以了
也就是去掉这段对应smali代码
sget-object v6, Lcom/android/internal/telephony/CommandsInterface$RadioTechnology;->RADIO_TECH_LTE:Lcom/android/internal/telephony/CommandsInterface$RadioTechnology;if-eq v4, v6, :cond_235invoke-virtual {p0}, Lcom/android/internal/telephony/MMDataConnectionTracker;->isRadioTechEvdo()Zmove-result v6if-eqz v6, :cond_262这样做之后，开机时便可看到弹出的是否使用数据的对话框了
7.13增加
启用设置中灰色的网络选项
修改Phone.apk\com\android\phone\Settings.smali
